Description

[Detailed Description of the Invention] [Industrial Application Field] This invention relates to an automatic cleaning device for cloth used in a filter machine.

[Conventional technology]

Pressurized filter presses called filter presses are often used in over-processing and wastewater treatment processes in various manufacturing plants such as the food industry and textile industry.
It is usually built into this machine.

This automatic cleaning type filter machine is designed so that by simply turning on the start switch, the cycle of over-squeezing and cake discharge is performed a certain number of times, then the cloth is washed, and the filter starts again.

[Problem that the invention attempts to solve]

However, in this automatic cleaning filter machine,
Since over-squeezing, squeezing, cake discharge and cloth washing are carried out on the same rack, washing water is applied directly to the cake, making it difficult to treat the cake.Since an automatic washing device is built into the over-pressing machine, the machine itself becomes larger and more complex. There were other problems, such as the complicated electrical circuit, which caused many malfunctions and breakdowns, and the impossibility of pickling cloth.

In addition, in the cloth cleaning process of this automatic cleaning type filter machine, as shown in FIG.
moves here, and the pipe 44 stands up between the cloth 45 and sprays jet water for cleaning, but because the cloth 45 is slanted, the distance from the spray nozzle is different between the top and bottom, which causes cleaning spots. In addition, there were drawbacks such as the fact that only one side could be cleaned.

[Means for solving problems]

In order to solve the above-mentioned problems, this idea is to separate the cloth from the machine, remove the cloth, and hang it on the standby section of the machine. A waiting section, a cleaning section, and a drying section are arranged in succession, and the waiting section and the drying section are moved by a chain in a direction perpendicular to the direction of the washing section. It consists of a pair of standpipes with injection nozzles arranged in the same direction at a required interval, a drive device that reciprocates the standpipes in the transverse direction, and a wastewater treatment section at the bottom. It is designed to be cleaned with jet water.

[Effect]

According to this idea, the cloth to be washed is removed from the washing machine one by one, folded in half on a rod, hung, and arranged in a waiting section, and then moved one by one to the washing section, where each section is uniformly sprayed with water from both sides. The waste water is then treated in the treatment section, and after washing, the cloth is dried in the drying section. Also, depending on how dirty the cloth is, a pair of standpipes,
That is, the optimum cleaning effect can be produced by moving the spray nozzles closer together or farther apart.

〔Example〕

1 to 3 show an embodiment of this invention. The automatic cloth cleaning device of this embodiment suspends the cloth 1 folded in half at the fold, so that the rod 2 placed in the transverse direction is moved by a pair of endless annular chains perpendicular to the rod 2. It consists of a standby section 3, a washing section 4, and a drying section 5 which are arranged in series and have approximately the same height.

In the standby section 3, a rotary shaft 8 driven by a deceleration motor 7 is attached to the upper end of a frame 6 of a required height, and a rotating shaft 8 is installed between the rotating shaft 8 and the idle chain gear 10 at the front upper end of the frame 9 of the cleaning section 4. A pair of endless annular chains 12 are installed via chain gears 11, and the chains 12
It has a rectangular parallelepiped shape with a plurality of rod hooks 13 attached at required pitches, and a required amount of cloth 1 removed from the washing machine is suspended in the washing section 4.
This is where the cloth 1 is automatically fed one by one.

The cleaning section 4 includes a pair of vertical upright pipes 17 standing upright on a nozzle stand 16 that rides on a pair of transverse rails 14 and is movable via rollers 15;
Screw shaft 1 that reciprocates this nozzle stand 16
It consists of a drive device consisting of a drive unit 8, etc., and a concave wastewater treatment section 19 at the bottom, and the cloth 1 hanging from a rod 2 that stops at the center is washed with water sprayed from both sides.

In both standpipe 17, spray nozzles 20 are arranged in a line corresponding to the cloth 1 from top to bottom in facing directions, and are connected to each other by a washing water pump 21 installed close to the stand. (The tube is not shown) Jet water can be evenly applied to the cloth 1.

The screw shaft 18 of the drive device is rotated by a directly connected deceleration forward/reverse motor 22, and
The entire surface of the cloth 1 can be completely cleaned by reciprocating the nozzle stand 16 in the transverse direction at a required speed through a female thread 23 fixed to the center of the lower surface of the cloth 1 and meshing with the screw shaft 18.

A pair of left and right short rotating shafts 25 having chain gears 24 at the front and rear ends are attached to the upper surface of the frame 9, and an endless annular chain 26 is installed between both chain gears 24 and is driven by a deceleration motor 27. Ru. A bar hook 13 is attached to the chain 26.

The drying section 5 is symmetrical to the standby section 3, and a rotary shaft 30 driven by a deceleration motor 29 is attached to a frame 28 standing up at the rear end, and a chain 31 is equipped with bar hooks at equal pitches. 13 is installed. This drying section 5 may also be equipped with a heater or a hot air fan for forced drying.

The standby section 3, washing section 4, and drying section 5 send the cloths 1 from the standby section 3 one by one to the washing section 4 one by one by simply turning on the start switch, and the washing section 4 stops the cloths 1 at a predetermined position. Jet water is ejected from the injection nozzle, the nozzle stand moves back and forth, and when cleaning is completed, it is sequentially transferred to the drying section 5, and the waste water flows into the waste water treatment section 19.

Note that the attachment of the cloth 1 to the standby section 3 and the removal of the cloth 1 from the drying section 5 can be performed not only manually but also by an automatic device.

Further, the pair of upright pipes 17 can be moved in the direction of proximity thereof through elongated holes 37 provided in the nozzle stand 16. For this reason, if the cloth is heavily soiled, loosen the tightening nut (not shown) and move the standpipe 17, that is, the nozzle, closer to the cloth, so that proper cleaning can be achieved even if the nozzle moves at the same lateral movement speed. It will be done. In this way, the optimum cleaning effect can be produced by adjusting the distance between the cloth and the nozzle as appropriate depending on how dirty the cloth is.

FIGS. 4 and 5 show other embodiments of this invention. In this embodiment, a pickling section mainly consisting of a pickling tank 31 is provided in front of a standby section 3. In this pickling section, an endless annular chain 34 driven by a deceleration motor 33 is attached to the upper surface of a frame 32, and a pair of upright cylinders 35 are installed on the sides of the tank at the rear of the tank to pull up the cloth 1 immersed in the tank.
A pair of horizontal cylinders 36 for transporting the pulled cloth 1 to the waiting section 3 are attached.

It goes without saying that this pickling section is omitted for fabrics that do not require pickling.
