Description

[Detailed Description of the Invention] This invention applies vibration to a furnace cloth hanging rod installed horizontally in a direction perpendicular to the hanging furnace cloth pressing/tasseling direction. This invention relates to a furnace cloth vibrating device for a filter press that shakes off the furnace cloth attached to the furnace cloth by shaking the furnace cloth.

As a conventional example of a furnace cloth vibrating device for this type of filter press, the vibrating head is lowered to a position where it comes into pressure contact with the furnace cloth hanging rod, and then the vibrating head is driven forward and backward to vibrate the furnace cloth by the action of the corrugated portion at the lower end of the vibrating head. The rotating motion of the oscillating object (Special Publication No. 54-19622) or crank is transmitted to the vibrating head, which gives circular motion to the vibrating head that is in pressure contact with the furnace cloth hanging rod.
This swings the hearth cloth (Tsubaki Kimishō 54-247)
No. 47) are known. However, the configuration in which the oven cloth hanging rod is oscillated by the corrugated portion at the lower end of the vibrating head has a problem in that the oven cloth is easily damaged because the oven cloth is rubbed by the sliding action of the vibrating head.

In addition, in a configuration that gives medium motion to the vibrating head, the direction change operation is slow in the reciprocating cycle of the vibrating head.
The disadvantage is that the impact applied to the furnace cloth hanging rod is weak and the swinging effect of the furnace cloth is not sufficient.

The present invention aims to solve the above-mentioned drawbacks of the conventional furnace cloth vibrating device for a filter press, and to provide a source cloth vibrating device for a filter press that can sufficiently vibrate the furnace cloth without damaging the furnace cloth. This is the purpose. Hereinafter, one embodiment of the filter press furnace cloth vibrating device of the present invention will be described based on the drawings. As shown in Figure 2, a furnace cloth hanging rod 3 is hung between the arms 1, 1 protruding from both ends of the upper part of each furnace plate through coil springs 2, 2, and the furnace cloth hanging rod 3 is suspended from the furnace cloth hanging rod 3. In a filter press in which a cloth 4 is sandwiched between each furnace plate, a furnace cloth vibrating device is configured to vibrate the furnace cloth suspension 3 and swing the furnace cloth 4.

It consists of a crank 8 that is installed on the head mount 6 to reciprocate the head mount 6, and an elevator 9 that is installed on the head mount 6 and reciprocates the vibrating head 7. The action causes the vibrating head to move up and down in a zigzag pattern.

The movable base 5 is in the shape of a rectangular parallelepiped frame, and has a pair of left and right base guide rails 10, 10 made of channel steel arranged above the furnace cloth hanging rod 3 and parallel to the source plate guide rail of the filter press.
The upper and lower surfaces of the movable base 5 are sandwiched by guide rollers 11, 11, . At the same time, a pair of chain conveyors 12, 12 are installed along the base guide rails 10, 10, and the movable base 5 is connected to the chain conveyor via connecting pieces 13, 13 protruding from both sides of the movable base 5. 12.12, and by reciprocating the chain conveyors 12, 12 by a motor (not shown), the movable base 5 is moved forward and backward in the direction of compressing and tufting the furnace cloth 4.

As shown in FIG. 3, the head mounting base 6 consists of a pair of front and rear horizontal frames 14a, 14b and an elevating rhombus mounting seat 15 that connects the horizontal frames 14a, 14b. For the left and right guide keys 16, 16 constructed toward the
While freely sliding the outside drum, the movable base 5
The front end of the head mounting base 6 is connected via a connecting rod 18 to a crank 8 provided on the front side of the head mounting base 6, and the head mounting base 6 is moved forward and backward by the rotational drive of the crank 8 using a motor 19 as a drive source. I have to. The elevating drive device 9 consists of a air cylinder, and is mounted on the elevating bag calendar mounting seat 15 of the head mounting base 6 with its piston rod 20 facing downward, and the vibrating head 7 connected to the piston rod 20 is directed downward. It is designed to move up and down toward the furnace cloth hanging rod 3 arranged therein.

A pair of guide shafts 21 are further provided at the upper end of the vibrating head 7.
, 21 are installed vertically, and the guide shafts 21, 21 are installed in the front and rear horizontal frames 14a, 14b of the head mounting base 6.
, 22 so that the vibrating head 7 can be smoothly raised and lowered relative to the head mounting base 6. The pressurized air supply pipe connected to the cylinder part of the lifting drive rhombus 9 is arranged above the base guide rails 10, 10 with sufficient slack to allow movement of the movable base 5. ing.

In this embodiment, the crank 8 is set to move the head mounting base 6 forward and backward in multiple cycles for one lifting/lowering cycle of the vibrating head 7.
A zigzag motion is performed in the front and back direction multiple times during the descending process.

The operation of this oven cloth vibrator will be described in detail below with reference to FIGS. 5A and 5B.

When the filter press has been compressed and the furnace plate and furnace cloth 4 are in a retracted state, the chain conveyor 12
12 is driven to move the movable base 5 onto the furnace cloth 4.

Next, pressurized air supply V supply control means and motor 1 (not shown) are connected.
9 starts driving, and the vertical reciprocating drive by the elevating drive device 98 and the forward and backward reciprocating drive of the head mount 6 by the crank 8 combine to move the vibrating head 7 within a predetermined vertical plane perpendicular to the furnace cloth suspension 3. It moves up and down in a zigzag pattern. That is, in the lowering process of the vibrating head 7 by the elevating drive device 9 (indicated by the arrow P in FIG. 5A), the movement of the head mounting base 6 by the crank 8 (indicated by the arrows P2 and P2 in FIG. 5A) ) is performed for multiple cycles, and the vibrating head 7 is
5B, perform a zigzag downward movement as shown by the arrow P3, and move the furnace cloth hanging twill 3, which is in pressure contact during the descent, backwards from the coil'spring 2, as shown by the arrow P3' in Fig. 5B. The furnace cloth 4 is alternately pushed downward and rearward downward, and as a result of this action, a downward dusting motion is applied to the furnace cloth 4, and at the same time, it swings back and forth, and the furnace cloth 4 adhering to the furnace cloth 4 is effectively brushed off. Ru. In addition, in the case of the ascending process of the vibrating head 7, the vibrating head 7 similarly follows a zigzag-like stroke, and the furnace cloth 4
A fluttering action and shaking occur, and the furnace port is removed. According to the furnace cloth vibrating device of the present invention, the head mounting table 6, which is provided on the movable base 5 and is movable in either the direction of compressing/pulling the furnace cloth 4 or the vertical direction, is attached to the movable base 5. While reciprocatingly driven by the first reciprocating means (crank 8) provided in the
