It includes domestic sewage, industrial wastewater and other useless water such as the first rain runoff into the drainage pipe network. In order to reduce the impact of wastewater on the environment, wastewater needs to be treated before being discharged. In the previous process of wastewater treatment, wastewater filtering equipment is required to pre-filter solid debris in the wastewater.

[0003] However, in the process of using the existing wastewater filtering equipment, when it is necessary to clean the debris on the filter mesh plate, the filter mesh plate usually needs to be removed to complete the cleaning, which is rather troublesome, and the wastewater filtering needs to be stopped during the cleaning process, affecting the wastewater filtering efficiency.

[0004] Therefore, it is necessary to provide a new wastewater filter to solve the above technical problems. Summary of the Utility Model

[0005] The technical problem solved by the utility model is to provide a wastewater filter that is convenient for cleaning debris on the filter mesh plate and does not need to stop wastewater filtering during the cleaning process.

A connecting cylinder is fixedly installed at the top of the water receiving tank, and a filtering cylinder is fixedly installed at the top of the connecting cylinder. Rotating shafts are rotatably installed on the inner walls of both sides of the filtering cylinder, and both ends of the rotating shafts extend outside the filtering cylinder. Two first filter mesh plates are fixedly installed on the outer walls of the rotating shafts, and the included angle between the two first filter mesh plates is 90 degrees. A partition plate is fixedly installed on the inner wall of the filtering cylinder, and the top of the partition plate is in contact with the rotating shaft.

Two slot blocks are fixedly installed on the outer wall of the filtering cylinder close to the hand rod, and the end of the plug pin away from the end plate extends into one of the slot blocks. A wastewater inlet hopper is fixedly installed on the outer wall of the filtering cylinder.

[0007] Preferably, a maintenance opening is provided on the inner wall of the filter cylinder, and a maintenance cover for sealing the maintenance opening is rotatably installed on the outer wall of the filter cylinder. A fixing rod is fixedly installed on the outer wall of the filter cylinder, a rotating arm is rotatably sleeved on the fixing rod, a resisting screw rod is penetrated and threadedly installed on the rotating arm, and the bottom end of the resisting screw rod contacts the maintenance cover.

[0013] The present utility model provides a wastewater filter. Through the arrangement of components such as a filter cylinder, a rotating shaft, two first filter screen plates, a partition plate, a hand rod, a plug pin, an end plate, a tension spring, etc., the upper first filter screen plate serves as a commonly used filter screen plate, and the lower first filter screen plate serves as a spare filter screen plate. When general impurity cleaning of the commonly used filter screen plate is required, only by rotating the hand rod by 90 degrees, the commonly used filter screen plate can be rotated to a state where the filtering surface is inclined downward, so that the attached solid sundries fall downward.

DETAILED DESCRIPTION

[0023] The utility model is further described below in conjunction with the accompanying drawings and implementation modes.

[0024] Please refer to Figures 1 - 7 ,in, Figure 1 A schematic structural diagram of a preferred embodiment of the wastewater filter provided by the utility model; Figure 2 for Figure 1 An enlarged schematic diagram of part A is shown; Figure 3 for Figure 1 An enlarged schematic diagram of part B is shown; Figure 4 for Figure 1 The front cross-sectional view shown; Figure 5 for Figure 1 The cross-sectional structural schematic diagram of the filter cartridge shown; Figure 6 2 is a schematic diagram of the structure of the hand lever; Figure 7 for Figure 1Schematic structural diagram of the described garbage receiving bin. The wastewater filter includes: a water receiving tank 1 and a garbage receiving bin 2 arranged on one side of the water receiving tank 1. A connecting cylinder 3 is fixedly installed at the top of the water receiving tank 1, and a filtering cylinder 4 is fixedly installed at the top of the connecting cylinder 3. The connecting cylinder 3 communicates the water receiving tank 1 and the filtering cylinder 4. The filtered wastewater enters the water receiving tank 1 through the connecting cylinder 3. A water outlet pipe is fixedly installed on the outer wall of one side of the water receiving tank 1. Rotating shafts 6 are rotatably installed on the inner walls of both sides of the filtering cylinder 4. Both ends of the rotating shaft 6 extend outside the filtering cylinder 4. Two first filter plates 7 are fixedly installed on the outer wall of the rotating shaft 6. The included angle between the two first filter plates 7 is ninety degrees. Refer to Figure 4 , the first filter plate 7 located above is the commonly used filter plate, and the first filter plate 7 located below is the spare filter plate. When there are relatively many solid impurities attached to the first filter plate 7, rotate the rotating shaft 6 counterclockwise by ninety degrees. The rotating shaft 6 drives the two first filter plates 7 to rotate. The first filter plate 7 (spare filter plate) originally located below then reaches the position of the first filter plate 7 (commonly used filter plate) originally located above, and continues to filter the wastewater. After the commonly used filter plate rotates ninety degrees, its filtering surface becomes inclined downward, and the solid impurities attached to it can fall. A partition plate 8 is fixedly installed on the inner wall of the filtering cylinder 4. The top of the partition plate 8 is in contact with the rotating shaft 6. The solid impurities filtered out slide down along the partition plate 8 into the garbage discharge cylinder 9, and finally fall into the garbage receiving bin 2. A garbage discharge cylinder 9 is fixedly installed on the outer wall of the filtering cylinder 4. One end of the garbage discharge cylinder 9 away from the filtering cylinder 4 extends into the garbage receiving bin 2. One end of the rotating shaft 6 is fixedly installed with a hand rod 10. A bolt 11 is inserted through and slidably installed on the hand rod 10. One end of the bolt 11 away from the filtering cylinder 4 is fixedly installed with an end plate 12. A tension spring 13 is sleeved on the bolt 11. One end of the tension spring 13 is fixedly connected to the hand rod 10, and the other end is fixedly connected to the end plate 12. Two slot blocks 14 are fixedly installed on the outer wall of the filtering cylinder 4 close to the hand rod 10. One end of the bolt 11 away from the end plate 12 extends into one of the slot blocks 14. The bolt 11 is located in the slot block 14 under the holding force of the tension spring 13, which can prevent the hand rod 10 from rotating. When the hand rod 10 is restricted, the rotating shaft 6 cannot rotate either, so that the two first filter plates 7 are kept in the current position. A wastewater inlet hopper 5 is fixedly installed on the outer wall of the filtering cylinder 4.

[0025] In this embodiment, in order to facilitate relevant personnel to manually clean impurities on the two first filter plates 7, an inspection port is opened on the inner wall of the filter cartridge 4, and an inspection cover 15 for sealing the inspection port is rotatably installed on the outer wall of the filter cartridge 4. A fixing rod 16 is fixedly installed on the outer wall of the filter cartridge 4, and a rotating arm 17 is rotatably sleeved on the fixing rod 16. A resistance screw 18 passes through and is threadedly installed on the rotating arm 17. The bottom end of the resistance screw 18 contacts the inspection cover 15. The resistance screw 18 is rotated counterclockwise to move it upward and separate from the inspection cover 15. Then the rotating arm 17 can be rotated to dislocate the resistance screw 18 and the inspection cover 15. After that, the inspection cover 15 can be opened. After the inspection cover 15 is opened, the impurities of the two first filter plates 7 can be cleaned through the inspection port.

[0026] In this embodiment, in order to reduce the amount of waste water entering the garbage receiving box 2 as much as possible, two water baffles are fixedly installed on the outer wall of the rotating shaft 6.

[0027] In this embodiment, in order to block the smell in the garbage receiving box 2, a cover plate 20 is slidably installed on the top of the garbage receiving box 2, and a handle is fixedly installed on the top of the cover plate 20, through which the cover plate 20 can be pulled away.

[0028] In the present embodiment, in order to automatically return the waste water flowing into the garbage receiving box 2 to the water receiving box 1, a water seepage chamber 21 is provided in the garbage receiving box 2, and a second filter screen plate 22 is fixedly installed at the bottom of the water seepage chamber 21. The mesh diameter of the second filter screen plate 22 is smaller than that of the first filter screen plate 7. The waste water passes through the second filter screen plate 22 and enters the water seepage chamber 21. A connecting pipe 19 connected to the water seepage chamber 21 is fixedly installed on the outer wall of the garbage receiving box 2. One end of the connecting pipe 19 away from the garbage receiving box 2 is fixedly connected to the connecting tube 3. When the liquid level of the waste water is higher than the connecting pipe 19, it will enter the connecting tube 3 through the connecting pipe 19 and finally flow into the water receiving box 1.

[0029] In this embodiment, in order to limit the rotatable range of the hand lever 10, two limit blocks are fixedly installed on the outer wall of the filter cylinder 4 on one side close to the hand lever 10. The hand lever 10 is located between the two limit blocks, and the two limit blocks limit the range of the hand lever 10 to ninety degrees.

[0030] The working principle of the wastewater filter provided by the utility model is as follows:

[0031] During use, the wastewater enters the filter cartridge 4 through the wastewater inlet hopper 5. Under the action of gravity, the wastewater passes through the two first filter plates 7 downward and flows into the connecting cylinder 3, and finally enters the water receiving tank 1. The solid debris in the wastewater will be intercepted by the upper first filter plate 7. Under the action of gravity and the impact of water, the intercepted solid debris will roll downward and enter the garbage discharge cylinder 9 under the guiding action of the partition plate 8. Finally, the solid debris will fall into the garbage receiving box 2 through the garbage discharge cylinder 9;

[0032] In addition to the solid debris entering the garbage receiving box 2, some wastewater will also enter the garbage receiving box 2. As the wastewater accumulates continuously, it will enter the water seepage chamber 21. The second filter plate 22 can intercept the solid debris to prevent it from entering the water seepage chamber 21. When the liquid level of the wastewater is higher than the connecting pipe 19, the excess part will automatically drain into the water receiving tank 1 through the connecting pipe 19, which can prevent the wastewater in the garbage receiving box 2 from accumulating and overflowing;

[0033] During the filtration process of the first filter plate 7, some solid debris will adhere to the filter plate or get stuck in the mesh holes. Therefore, these impurities need to be cleaned regularly, otherwise it will affect the permeability of the first filter plate 7. During regular cleaning, hold the hand rod 10 with one hand and pull the end plate 12 backward with the other hand. The end plate 12 drives the bolt 11 to move backward, causing the bolt 11 to withdraw from the upper slot block 14. During this process, the tension spring 13 will be stretched. Then rotate the hand rod 10 counterclockwise by 90 degrees, causing the hand rod 10 to collide slightly with the lower limit block. The hand rod 10 drives the rotating shaft 6 to rotate counterclockwise, and the rotating shaft 6 drives the two first filter plates 7 to rotate counterclockwise. The first filter plate 7 that was originally at the lower position will reach the position of the first filter plate 7 that was originally at the upper position and continue to filter the wastewater. At this time, the filter surface of the first filter plate 7 that was originally at the upper position becomes inclined downward, and the debris attached to it can fall. When the hand rod 10 collides slightly with the lower limit block, the first filter plate 7 will be vibrated, and the debris stuck in the first filter plate 7 can be shaken off. Then rotate the hand rod 10 clockwise to the initial position (in contact with the upper limit block), and then release the end plate 12. Under the pulling force of the tension spring 13, the bolt 11 will automatically insert into the upper slot block 14. Since the upper first filter plate 7 has been cleaned, it can continue to filter the wastewater within a certain time range;

[0034] After the wastewater filter has been used for a long period of time, the inspection cover 15 can be opened to carefully manually clean the two first filter screens 7. When opening, the abutting screw 18 is turned counterclockwise to separate it from the inspection cover 15, and then the rotating arm 17 is rotated to misalign the abutting screw 18 and the inspection cover 15. In this way, the inspection cover 15 loses its restriction and can be opened afterwards. After opening the inspection cover 15, the first filter screen 7 located on the top can be cleaned of debris through the inspection port first. Afterwards, the hand lever 10 is turned counterclockwise by ninety degrees and restricted by the latch 11. The first filter screen 7 originally located at the bottom can be rotated to the position of the first filter screen 7 originally located at the top and is in a restricted state. Subsequently, relevant personnel can clean impurities from the first filter screen 7 at the bottom.

[0035] Compared with the related art, the wastewater filter provided by the utility model has the following beneficial effects:

[0036] The utility model provides a wastewater filter, through the arrangement of components such as a filter cartridge 4, a rotating shaft 6, two first filter screen plates 7, a partition plate 8, a hand lever 10, a latch 11, an end plate 12, and a tension spring 13, the first filter screen plate 7 located at the top is used as a common filter screen plate, and the first filter screen plate 7 located at the bottom is used as a spare filter screen plate. When it is necessary to clean the common filter screen plates for general impurities, it is only necessary to rotate the hand lever 10 90 degrees to rotate the common filter screen plates to a state where the filter surface is tilted downward, so that the attached debris falls downward, and then the hand lever 10 is slightly collided with the limit block several times, After the handle 10 is rotated ninety degrees, the spare filter screen plate will be in the position of the common filter screen plate, and the impurities can continue to be filtered. The whole operation is convenient and there is no need to stop the wastewater filtration. Through the arrangement of the seepage chamber 21, the second filter screen plate 22 and the connecting pipe 19, when the wastewater level in the garbage receiving box 2 exceeds the height of the connecting pipe 19, the excess part will automatically enter the water receiving box 1 through the connecting pipe 19, thereby avoiding the situation where the wastewater in the garbage receiving box 2 accumulates too much and overflows, and the use is reliable.
