Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a frame type filter press, and more specifically, a cloth is suspended and supported on both sides of the frame,
A stock solution is introduced into the chamber formed between the frames through a stock solution hole provided in the center of the fabric, and the filtered solution is taken out through a hole drilled in the frame, and the residue is discharged by opening the frame.

Prior Art The frames used in this type of filter press are generally quite heavy and inconvenient to handle, and require a relatively large driving force to move the frame, resulting in high costs. There's a problem. Also,
It is necessary to have a means to maintain the distance between the cloths and to vibrate the cloths to prevent them from sticking together, but if this means is provided integrally with the frame by laminating wire mesh, the shape of the frame will change. It gets complicated. Furthermore, it is generally necessary to also assemble a stock solution supply plate to the stock solution hole in the fabric, making assembly difficult.

Purpose of the Invention The present invention was made in view of the above-mentioned problems, and aims to reduce the weight by simplifying the shape of the frame.
A member with a simple shape that is easy to vibrate is provided separately from the frame to maintain the distance between the cloths, and the member, cloth, and stock solution supply plate are assembled together to improve assembly workability. This reliably prevents coalescence and also prevents excessive performance degradation due to the member.

The frame has a simple shape roughly in the shape of a "R" shape to reduce its weight, and separately from the frame, there is a cloth spacing holding part made of a thick plate, a stock solution hole connecting part, and a space holding part and stock solution hole coupling part made of a thick plate. A distance maintaining and vibrating device is provided which is made up of connected thin plates, and a central solution hole is provided in the distance maintaining and vibrating device, a center solution hole is provided on both sides of a bag-like cloth that covers the frame, and left and right holes are provided on the outside of the cloth. The periphery of the central stock solution hole of a pair of stock solution supply plates is fixed together, and the frames to which this cloth and the spacing holding and vibrating device are attached are movably arranged side by side, and the frames are brought into contact with each other so that they face each other. A frame type characterized in that the entire circumference of the cloth is closed to form a chamber, the concentrated solution is supplied to the chamber through the concentrated solution hole, and the residue is discharged by moving and opening the frame. It is provided with a filter press.

The cloth 2 has a long shape in the front and back direction, and has stock solution holes 10A and 10B approximately in the center of both sides 2a and 2b.
has been established. The cloth 2 is hung so as to cover the outer periphery of the frame 1 with its upper end surface 2d straddling the upper surface of the upper frame portion 1a of the frame 1, and is suspended and supported.
0A and 10B are positioned approximately at the center of the gap within the frame 1.

The above-mentioned spacing holding and vibrating device 3 is shown in FIGS. 2 and 3.
The one shown in the figure consists of a square-shaped spacer 11 made of a thick plate, and a thin plate with spring properties connected to the center of the upper and lower frames so as to pass through the center of the gap surrounded by the spacer 11. A diaphragm section 12 and an annular stock solution hole connecting section 1 provided at the center of the diaphragm section 12.
3 are integrally formed. That is, the spacing section 11 of the outer frame and the stock solution hole connecting section 13 at the center are connected by a diaphragm section 12 consisting of a pair of leaf springs.

The spacing holding and vibrating device 3 is inserted into the cloth 2 suspended and supported by the frame 1, and installed in parallel between both sides 2a and 2b. 10B, annular stock solution supply plates 4A and 4B are abutted on the outside of each plate, and these are fastened and fixed with fasteners 15. In this way, the spacing holding and vibrating tool 3 and the stock solution supply plate 4A,
4B is assembled to the frame 1 by integrally fixing it to the cloth 2.

As shown in FIG. 1, the single filter press is constructed by assembling the frame 1, the cloth 2, the spacing/vibrating device 3, and the stock solution supply plates 4A and 4B, and is arranged between a fixed plate 20 and a movable plate 21, as shown in FIG. They are arranged side by side so that they can be moved. When the movable plate 21 is moved to the fixed plate 20 side and the frames 1 are brought into contact with each other to form a continuous state, the entire circumference of the side surfaces 2a and 2b of the cloth 2 suspended from the opposing sides of the adjacent frames 1 is frame 1,1
The chamber 25 is sandwiched between the chambers 25 and 25 and closed tightly. Each chamber 25 communicates through a stock solution distribution part such as the stock solution supply plate 4A, and the upstream end communicates with a stock solution press-in tube 26 provided through the fixed plate 20.

The liquid flowing out from the chamber 25 through the cloths 2a and 2b into the gap in the frame 1 is drained through liquid extraction holes 8A and 8B opened at the lower corners of the inner circumferential surface of the frame 1 through holes bored in the lower ears 5C and 5D. It is taken out through through holes 7C and 7D.

By having the above configuration, in the event of an
When a stock solution supply pump (not shown) is connected to the stock solution injection pipe 26 and the stock solution is pumped, the stock solution supply plate 4
The stock solution is filled at high pressure into each chamber 25 through a stock solution distribution section such as A. For this reason, the cloth 2 sandwiching the frame 1

and the stock solution hole connecting portion 13.

After this, the frames 1 are moved to widen the spaces between adjacent frames 1 to open the frames and discharge the residue. Since the diaphragm part 12 of the spacing holding and vibrating tool 3 is formed of a thin plate with spring properties, it vibrates easily when the frame moves or the residue is peeled off, giving vibration to the cloth 2 on both sides, and causing the cloth 2a to vibrate. , 2b from clogging with residue. To wash the cloth, apply cleaning liquid from either the upper or lower ear through-hole as necessary to the cloth 2a in the frame,
This is done by supplying between 2b and 2b.

The present invention is not limited to the above-mentioned embodiments, but as shown in FIG. 4, the outer frame of the spacer and vibrator may be formed so that the cross section of the outer frame is inclined so that the width becomes thinner toward the inner circumference. Further, as shown in FIGS. 5 and 6, the spacing holding and vibrating device is made of synthetic resin, and the undiluted solution hole connecting portion 13' is formed in a roughly inverted U shape, while the vibrating plate portion 12' is On the outer periphery of the stock solution hole connecting portion 13', a ring is formed in a roughly inverted U shape from the connecting portion 13' through an arm, so that the flow of the stock solution downward from the stock solution hole connecting portion 13' is formed in an inverted U shape. At the same time, the distance between the cloths facing each other can be sufficiently maintained in the outer circumferential portion except for the lower part of the liquid solution hole connection part 13', and the diaphragm part 12 It may be possible to make the cloth vibrate with the vibration of '.

Effects of the Invention As is clear from the above description, according to the frame type filter press according to the present invention, since the frame has a simple, roughly square shape, it is possible to reduce the weight and manufacture it at low cost. Also,
Since the distance between the cloths is maintained by a distance maintaining and vibrating device, it is possible to reliably prevent the cloths from sticking together, and since the distance maintaining and vibrating device is provided with a leaf spring section, it can be easily vibrated. , it is possible to prevent clogging of the cloth by applying vibration to the cloth. Moreover, the spacing holding and vibrating tool can be assembled integrally with the stock solution supply plate to the cloth, and has the advantage that the assembly work is extremely simple.
