Description

Technical Field

[0002] According to the patent document with the authorization announcement number of "CN116272070B" and the invention name of "A high-salt wastewater treatment process", it is recorded in its specification that the filter plate is inclined in the main body, and the wastewater entering the main body in the liquid inlet pipe is filtered by the filter plate, and the wastewater will also flow downward along the inclined surface of the filter plate, thereby driving the impurities filtered out on the surface of the filter plate toward the lower part of the inclined direction of the filter plate, and then the impurities filtered out on the filter plate are concentrated on the filter plate near the outlet. After that, the staff regularly opens the blockage at the outlet to clean up the impurities gathered near the outlet to avoid the accumulation of impurities and cause the filter holes on the filter plate to be blocked. At the same time, because the impurities filtered out on the filter plate are gathered near the outlet under the inclination angle of the filter plate itself and driven by the water flow, the impurities retained on other parts of the filter plate surface are relatively small, which can reduce the possibility of filter plate blockage to a certain extent and extend the maintenance cycle of the filter equipment. However, the following defects still exist: During filtration, impurities will adhere to the surface of the filter plate or in the filter holes and may not accumulate easily in low places, making it difficult for the impurities to self-clean. The filter plate is still more likely to be blocked, resulting in a low filtration efficiency for high-salt wastewater. Furthermore, the filtration effect of high-salt wastewater is poor when it is filtered through the filter plate once. Summary of the invention

[0014] Compared with the prior art, the present invention has the following beneficial effects: 1) During operation, an inclined filter belt is arranged inside the treatment chamber.

The active roller 605 rotates and drives the half gear 808 to rotate at the same time; When the half gear 808 is meshed with the tooth plate 807, the lifting piston plate 805 moves upward to push the wastewater to flow back from the reflux pipe body 804. After the half gear 808 is disengaged from the tooth plate 807, the lifting piston plate 805 moves back to take water again, so that the wastewater can be circulated for filtration, thereby improving the filtration effect of high-salt wastewater.

The tank switch unit 812 includes a connecting water tank 802 opened at the bottom end of the lifting chamber 801 near the treatment chamber 5, and a receiving tank 8121 is opened on the inner bottom wall of the connecting water tank 802.

An inlet pipe 3 is installed at the top of the reflux pipe body 804, and a drain pipe 4 is installed at the bottom of the treatment box 1. The drain pipe 4 is located below the wastewater storage chamber. Valves are installed on the inlet pipe 3 and the drain pipe 4, and a base 2 is symmetrically installed at the bottom of the treatment box 1.

[0023] Working principle: When working, firstly, the driving motor 606 is turned on, and the active roller 605 is started to rotate clockwise, thereby driving the filter belt 602 to move, and the top wall of the filter belt 602 moves upward, and then the valve on the liquid inlet pipe 3 is opened, and the high-salt wastewater is passed from the return pipe body 804 into the wastewater storage chamber, so that the high-salt wastewater is continuously filtered through the filter holes 603 on the filter belt 602, so that the impurities in the high-salt wastewater are at the top of the filter belt 602, and the filtered high-salt wastewater is stored in the wastewater storage chamber; As the filter belt 602 moves, the top of the scraper head 703 is in close contact with the middle of the bottom wall of the filter belt 602 due to the elastic force of the compression spring 704, so that the impurities attached to the surface of the filter belt 602 are scraped into the impurity storage chamber, avoiding the impurities from being brought back into the high-salinity wastewater; During the rotation of the active roller 605, the cam 7051 is driven to rotate by the first driven sprocket 7052, the first active sprocket 7053 and the first chain 7054. During the rotation of the cam 7051, intermittent pressure is applied to the top wall of the pressing plate 7057. When the pressure is applied, the flapping plate 7056 is pushed downward. When the pressure disappears, the flapping plate 7056 moves back upward, so that the flapping plate 7056 continuously flaps the inner bottom wall of the filter belt 602, thereby removing the particles attached to the filter holes 603 and the filter belt 602. 02, the impurities on the bottom wall are knocked down into the impurity storage chamber, which further facilitates the removal of the filtered impurities and facilitates subsequent filtration. During the rotation of the cam 7051, the air inlet pipe 7063 drives the outside air to enter the air below the pressure plate 702 in the plate slot 701 through the fan blades 7062 and the air inlet groove 7061, thereby generating pressure on the bottom wall of the pressure plate 702, so that the top of the scraper head 703 is pressed against the lower surface of the filter belt 602, thereby improving the scraping effect of the impurities on the filter belt 602; At the same time, part of the wastewater entering the wastewater storage chamber enters the lifting chamber 801 through the connecting water tank 802. According to the distance between the connecting vessels, the liquid level in the wastewater storage chamber is flush with the liquid level inside the lifting chamber 801. When the active roller 605 rotates, the second active sprocket 810, the second driven sprocket 809 and the second chain 811 drive the half gear 808 to rotate clockwise. When the half gear 808 is in meshing state with the tooth plate 807, the lifting piston plate 805 is driven to move upward, so that the wastewater above the lifting piston plate 805 is lifted up and pressed out from the reflux pipe body 804, so that the high The salt wastewater flows back from the return pipe body 804 to the wastewater storage chamber, and circulates and filters the impurities in the high-salt wastewater through the filter holes 603 on the filter belt 602, thereby improving the filtering effect and preventing some impurities from being squeezed into the wastewater storage chamber from the filter holes 603 on the elastic filter belt 602 under pressure and being difficult to be filtered. When the half gear 808 is disengaged from the tooth plate 807, the lifting piston plate 805 moves downward back to the original position under the action of gravity, and then after the half gear 808 is re-engaged with the tooth plate 807, it drives the lifting piston plate 805 to move upward again; When the lifting piston plate 805 moves upward, the baffle plate 8122 moves upward under the elastic force of the bottom spring 8124 until the top wall of the sealing plate 8123 is in close contact with the inner top wall of the connecting water tank 802, isolating the lifting chamber 801 from the processing chamber 5, preventing the wastewater in the lifting chamber 801 from directly flowing back, and preventing the wastewater from entering the space below the lifting piston plate 805. When the lifting piston plate 805 moves downward, pressure is generated on the side plate 8126, pushing the baffle plate 8122 to move downward, so that the wastewater can flow to the top of the lifting piston plate 805 again; After multiple cycles of filtration, the valve on the drain pipe 4 is opened to discharge the filtered waste water in the waste gas storage chamber, and then the cleaning door 608 is opened to clean the impurity storage chamber.
