Description

Technical Field

[0001] This application relates to the technical field of pickling, and in particular to a pickling device for a filter press. Background Art

[0002] In the process of industrial production, as an important separation device, the filter press is widely used in the separation operation of liquid and solid particles. However, after long-term use, impurities, dirt, and oxides are likely to accumulate on the filter screen and internal pipes of the filter press, which will not only reduce the filtering effect, affect product quality, but also have an adverse impact on the normal operation of the filter press, and even shorten the service life of the equipment.

[0003] To solve this problem, the industrial community usually uses pickling to clean and maintain the filter press. Pickling utilizes the corrosive effect of acidic solutions to effectively remove dirt and oxides on the filter screen and pipes, and restore the performance of the filter press.

A driving component for driving the mounting ring frame 9 to rotate is installed at one end of the base 1. A discharging mechanism is installed at one end of the base 1;

[0035] Among them, the driving component includes a driving rod 12 rotatably connected inside the hollow main rod 8. A driving motor 13 is fixedly connected to one end of the base 1.

[0038] During use, first, the acid pump 3 is externally connected to an acid pickling solution storage tank, and the acid pickling solution is input into the mixing tank 25. Then, the PH monitoring sensor 28 monitors the PH value of the acid pickling solution input into the mixing tank 25 by the acid pump 3. When the PH value of the acid pickling solution does not reach the predetermined value, the acid-resistant valve 27 is opened to pour the acidic raw material inside the acid storage tank 26 into the mixing tank 25 to be mixed with the acidic solution to adjust the PH value. Then, by starting the jet pump 5, the acidic solution inside the mixing tank 25 is pumped into the inside of the spray head pipe 6 through the acid guide pipe 4, and then sprayed onto the surface of the main filter screen 10 through the spray head pipe 6, and the surface of the main filter screen 10 is rinsed, so that the dirt on the surface of the main filter screen 10 is separated under the rinsing of the acidic solution;

[0039] At the same time, by starting the driving motor 13, the driving rod 12 is driven to drive the driving gear 14 to mesh with the driven gear 16.

[0040] Refer to Figure 1 and Figure 2 、 Figure 4 As shown in, the discharging mechanism includes a plurality of material guiding inclined grooves 19 uniformly opened at one end of the base 1. A plurality of sewage discharge grooves 20 adapted to the material guiding inclined grooves 19 are opened at one end of the base 1. The bottom of the hollow main rod 8 is uniformly rotatably connected with a plurality of sewage discharge filter screens 21.

One end of the mounting ring frame 9 is provided with a transmission component for driving the sewage discharge filter screen 21 to deflect;

[0041] Among them, the transmission component includes arc-shaped racks 22 uniformly fixedly connected to one side of the mounting ring frame 9.

[0044] During use, when the driving motor 13 is started to drive the mounting ring frame 9 to drive the main filter screen 10 to rotate, the mounting ring frame 9 drives a plurality of arc-shaped racks 22 to be engaged with the transmission gear 23 in sequence, and drives the transmission gear 23 to reciprocally deflect under the action of gravity, so that the transmission gear 23 drives the sewage filter screen 21 to reciprocally deflect around the hinge shaft. At the same time, the sewage filter screen 21 moves along the inner wall of the filter tank 7 to a position aligned with the material guiding chute 19, and the dirt inside the filter tank 7 is filtered and intercepted by the sewage filter screen 21, and then is obliquely pushed to a position aligned with the material guiding chute 19. Then, the dirt slides along the surface of the sewage filter screen 21 by gravity and falls into the sewage tank 20 through the material guiding chute 19 for collection, so as to facilitate the discharge and collection of the dirt falling into the filter tank 7. At the same time, the top of the sewage tank 20 is covered and protected by the protective cover 24, thereby reducing the situation of acid solution splashing outwards and effectively improving the safety of the device.

Then, the PH monitoring sensor 28 monitors the PH value of the acid pickling solution input into the mixing tank 25 by the acid pump 3. When the PH value of the acid pickling solution does not reach the predetermined value, the acid raw material in the acid storage tank 26 is poured into the mixing tank 25 through the anti-corrosion valve 27 to be mixed with the acid solution to adjust the PH value. Then, the acid solution in the mixing tank 25 is pumped into the inside of the spray head pipe 6 through the acid guiding pipe 4 by starting the jet pump 5, and then sprayed onto the surface of the main filter screen 10 through the spray head pipe 6 to form a flushing on the surface of the main filter screen 10;

At the same time, the driven gear 16 is engaged with the driving gear 18, and the mounting ring frame 9 is driven to drive the main filter screen 10 to rotate, so that the scraper 11 fits on the surface of the main filter screen 10 to scrape off dirt;

[0047] Next, the mounting ring frame 9 drives a plurality of arc-shaped racks 22 to be engaged with the transmission gear 23 in sequence, and drives the transmission gear 23 to reciprocally deflect under the action of gravity, so that the transmission gear 23 drives the sewage filter screen 21 to reciprocally deflect around the hinge shaft. At the same time, the sewage filter screen 21 moves along the inner wall of the filter tank 7 to a position aligned with the material guiding chute 19, and the dirt inside the filter tank 7 is filtered and intercepted by the sewage filter screen 21, and then is obliquely pushed to a position aligned with the material guiding chute 19. Then, the dirt slides along the surface of the sewage filter screen 21 by gravity and falls into the sewage tank 20 through the material guiding chute 19 for collection.
