Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, and in particular to a wastewater treatment device for chemical dosing. Background Technology

[0002] With the current pace of development, the amount of wastewater generated is also increasing. Wastewater is mainly divided into two categories: natural pollution and man-made pollution. The amount of man-made pollution is increasing, mainly due to the increase in industrial wastewater and domestic sewage. Therefore, in recent years, filtration and purification methods have been used to treat man-made wastewater in order to save some water resources. At the same time, most wastewater contains many chemical components, and chemicals need to be added during treatment before further filtration and purification can be carried out.

[0003] When using a chemical dosing wastewater treatment device to treat wastewater, the wastewater enters the device and mixes with the flocculant. Then, through sedimentation, the solid particles in the wastewater gather and fall to the bottom of the device. The wastewater entering the treatment device may also contain debris such as shredded paper that has not been filtered by the preliminary filtration equipment. After the debris enters the treatment device, it can easily cause blockages in the inlet pipe, outlet pipe, and sludge pumping pipe, affecting the normal use of the treatment device. In addition, the inlet pipe connected to the treatment device is relatively heavy, making it inconvenient to disassemble and clean. Utility Model Content

[0004] The purpose of this utility model is to solve the problem that the sewage entering the treatment device may contain debris such as shredded paper that has not been filtered by the preliminary filtration equipment. After the debris enters the treatment device, it can easily cause blockage of the inlet pipe, outlet pipe and sludge pumping pipe of the device, affecting the normal use of the treatment device. In addition, the inlet pipe connected to the treatment device is relatively heavy and inconvenient to disassemble and clean. Therefore, a chemical dosing sewage treatment device for sewage treatment is proposed.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a wastewater treatment device for chemical dosing, comprising a tank, an inlet pipe and an outlet pipe respectively provided on both sides of the tank, a drain pipe provided on one side of the bottom of the tank, a control valve provided at the top of the drain pipe, a dosing port for easy chemical dosing provided at the top of the tank, a convenient device provided at one end of the inlet pipe, the convenient device comprising a round pipe and a telescopic pipe, the telescopic pipe being fixed to one side of the round pipe, a flange provided at one end of the telescopic pipe and the round pipe respectively, the end of the telescopic pipe away from the round pipe being connected to the inlet pipe through the flange, and the bottom end of the round pipe being fixedly connected to one side of the tank through a connecting rod.

[0006] Preferably, the convenient device further includes a filter plate with a filter screen on its outer surface. The filter plate is installed on one end of the inner wall of the water inlet pipe via an auxiliary device. Grooved rods are fixedly connected to both sides of the round pipe. A sliding rod is slidably connected to the inner wall of the grooved rod. The end of the sliding rod away from the grooved rod is fixedly connected to the end of the telescopic pipe away from the round pipe. A screw is fixedly connected to one side of the sliding rod. A threaded ring is threadedly connected to the outer surface of the screw. A pressure block is rotatably connected to one side of the threaded ring. The pressure block slides on the outer surface of the screw, and the screw slides on one side of the inner wall of the grooved rod.

[0007] The effect achieved by the above components is as follows: By setting up a telescopic pipe, when using the sewage treatment device, the filter screen is installed on one end of the inner wall of the inlet pipe with the help of an auxiliary device. One end of the telescopic pipe is moved so that it fits against one side of the inlet pipe. One end of the telescopic pipe is connected to the inlet pipe through a flange. The threaded ring on the outer surface of the screw is rotated so that the threaded ring moves towards the grooved rod on the outer surface of the screw, pushing the pressure block to move. One side of the pressure block is pressed against the outer surface of the grooved rod and fixed at the position of the sliding rod and the telescopic pipe. Then, the end of the round pipe away from the telescopic pipe is connected to the sewage conveying pipe through a flange. Subsequently, the sewage is conveyed through the conveying pipe, passing through the round pipe, the telescopic pipe, and the inlet pipe. Enter the tank and add flocculants and other chemicals at the dosing port at the top of the tank to improve the treatment effect of sewage. When sewage passes through the filter screen, the filter screen on the outer surface of the filter screen can block paper scraps and other debris in the sewage. When it is necessary to clean the filter screen, rotate the threaded ring on both sides of the round pipe to make the threaded ring drive the pressure block away from the outer surface of the groove rod to release the position fixation of the sliding rod. Then disconnect the connection between the telescopic pipe and the inlet pipe, push the telescopic pipe to retract and make the sliding rod slide in the direction of the round pipe on the inner wall of the groove rod. This allows you to clean the inlet pipe and the filter screen without disconnecting the sewage delivery pipe connected to one end of the round pipe.

[0008] Preferably, a plurality of protruding strips are fixedly connected to one side of the pressure block, and the protruding strips are made of rubber.

[0009] The effect achieved by the above components is that when the side of the pressure block with the rubber protrusion is pressed against the outer surface of the groove rod to fix the position of the sliding rod and the telescopic tube, it is more stable and less prone to accidental slippage.

[0010] Preferably, a plurality of protrusions are fixedly connected to the outer surface of the threaded ring, and the protrusions are circumferentially distributed on the outer surface of the threaded ring.

[0011] The effect achieved by the above components is that by pressing the protrusion on the outer surface of the threaded ring with your hand, it is easier to push the threaded ring to rotate and it is less likely to slip.

[0012] Preferably, a sealing ring is fixedly connected to the outside of the flange at one end of the telescopic tube, and the sealing ring is made of rubber.

[0013] The effect achieved by the above components is that when the flange at one end of the telescopic pipe is connected to the flange on one side of the inlet pipe, the rubber sealing ring will be placed on the outside of the connection between the two flanges to further seal the outside of the connection and minimize sewage leakage.

[0014] Preferably, a stop is fixedly connected to the end of the screw away from the sliding rod, and the length of the stop is greater than the diameter of the screw.

[0015] The effect achieved by the above components is that by setting the stop, the movement range of the threaded ring on the outer surface of the screw can be limited, so as to avoid the threaded ring from falling off the screw surface and being lost when it moves outward.

[0016] Preferably, the auxiliary device includes two slots, which are fixed on both sides of the filter plate. A slider is slidably connected to the inner wall of the slot, and a spring is provided inside the slot. The slider is installed on one end of the inner wall of the slot by the spring. Two rectangular slots are opened on one side of the water inlet pipe, and a slot is opened at one end of the inner wall of the rectangular slot.

[0017] The effect achieved by the above components is as follows: When installing the filter plate, align the grooves on both sides of the filter plate with the two rectangular grooves on one side of the water inlet pipe, control the slider inside the two grooves to adhere to the outer surface of the water inlet pipe, push the filter plate to squeeze the slider, causing the slider to slide into the groove and compress the spring. After the filter plate is located on the inner wall of the water inlet pipe, the spring returns to its original state and pushes the slider outward to insert one end of the slider into the slot, and fix the threaded ring to one side of the water inlet pipe to complete the installation.

[0018] Preferably, a through groove is formed on one side of the slot block, and a groove is formed on one side of the slider.

[0019] The effect achieved by the above components is that when the filter screen needs to be removed, the slider can be pushed by hand at the groove on one side of the slot to move the slider into the slot, and then the filter screen can be pulled out.

[0020] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0021] In this invention, a convenient device is provided. By installing a filter screen plate on one end of the inner wall of the inlet pipe, the filter screen on the surface of the filter screen plate blocks impurities in the sewage, minimizing the risk of impurities entering the tank and causing blockage of the internal pipes. By controlling the contraction of the telescopic tube to expose one end of the inlet pipe, it is easy to clean the inlet pipe and filter screen plate without disconnecting the sewage conveying pipe connected to one end of the round pipe, thus improving the convenience of using the sewage treatment device.

[0030] Example 1, such as Figure 1-2 As shown, a wastewater treatment device for chemical dosing includes a housing 1. An inlet pipe 4 and an outlet pipe 6 are respectively provided on both sides of the housing 1. A drain pipe 7 is provided on one side of the bottom of the housing 1. A control valve is provided at the top of the drain pipe 7. A dosing port 5 for easy chemical dosing is provided at the top of the housing 1. A convenient device 2 is provided at one end of the inlet pipe 4. The convenient device 2 includes a round pipe 21 and a telescopic pipe 22. The telescopic pipe 22 is fixed to one side of the round pipe 21. A flange is provided at one end of the telescopic pipe 22 and the round pipe 21 respectively. The end of the telescopic pipe 22 away from the round pipe 21 is connected to the inlet pipe 4 through the flange. The round pipe 21 is fixed to one side of the housing 1 by a connecting rod.

[0031] Reference Figure 1-4As shown, in this embodiment: the convenient device 2 also includes a filter plate 26, the outer surface of which is provided with a filter screen. The filter plate 26 is installed on one end of the inner wall of the water inlet pipe 4 via an auxiliary device 3. Grooved rods 23 are fixedly connected to both sides of the round pipe 21. A sliding rod 24 is slidably connected to the inner wall of the grooved rod 23. The end of the sliding rod 24 away from the grooved rod 23 is fixedly connected to the end of the telescopic pipe 22 away from the round pipe 21. A screw 25 is fixedly connected to one side of the sliding rod 24. A threaded ring 27 is threadedly connected to the outer surface of the screw 25. A pressure block 28 is rotatably connected to one side of the threaded ring 27. The pressure block 28 slides on the outer surface of the screw 25, and the screw 25 slides on one side of the inner wall of the grooved rod 23. When using the sewage treatment device, the filter screen 26 is installed on one end of the inner wall of the inlet pipe 4 with the help of the auxiliary device 3, and one end of the telescopic pipe 22 is moved to fit against one side of the inlet pipe 4. The telescopic pipe 22 is connected to the inlet pipe 4 through the flange, and the threaded ring 27 on the outer surface of the screw 25 is rotated to move the threaded ring 27 in the direction of the groove rod 23 on the outer surface of the screw 25, pushing the pressure block 28 to move. One side of the pressure block 28 is pressed against the outer surface of the groove rod 23 to fix the position of the sliding rod 24 and the telescopic pipe 22. Then, the end of the round pipe 21 away from the telescopic pipe 22 is connected to the sewage conveying pipeline through the flange, and then... Wastewater is transported through a pipeline, passing through a circular pipe 21, a telescopic pipe 22, and an inlet pipe 4, into the tank 1. Flocculants and other chemicals are added to the tank 1 through the dosing port 5 at the top of the tank 1 to improve wastewater treatment. When the wastewater passes through the filter screen 26, the filter screen on its outer surface blocks debris such as paper scraps. To clean the filter screen on the surface of the filter screen 26, the threaded rings 27 are rotated on both sides of the circular pipe 21, causing the threaded rings 27 to move the pressure block 28 away from the outer surface of the grooved rod 23, thus releasing the position fixation of the sliding rod 24. Then, the connection between the telescopic pipe 22 and the inlet pipe 4 is released, pushing the telescopic pipe 22 to retract and causing the sliding rod 24 to... The inner wall of the groove rod 23 slides towards the circular tube 21, allowing for cleaning of the inlet pipe 4 and the filter plate 26 without disconnecting the sewage conveying pipe connected to one end of the circular tube 21. By setting up the convenient device 2, a filter plate 26 is installed on one end of the inner wall of the inlet pipe 4. The filter screen on the surface of the filter plate 26 blocks impurities in the sewage, minimizing the risk of impurities entering the tank 1 and causing blockage of the internal pipes. By controlling the retraction of the telescopic tube 22, one end of the inlet pipe 4 is exposed, facilitating cleaning of the inlet pipe 4 and the filter plate 26 without disconnecting the sewage conveying pipe connected to one end of the circular tube 21, thus improving the convenience of using the sewage treatment device.

[0032] Reference Figure 2-4As shown in this embodiment: a plurality of protrusions 29 are fixedly connected to one side of the pressure block 28. The protrusions 29 are made of rubber. When the side of the pressure block 28 with the rubber protrusions 29 is pressed against the outer surface of the groove rod 23 to fix the position of the sliding rod 24 and the telescopic tube 22, it is more stable and less prone to accidental slippage. A plurality of protrusions 210 are fixedly connected to the outer surface of the threaded ring 27. The protrusions 210 are circumferentially distributed on the outer surface of the threaded ring 27. By pressing the protrusions 210 on the outer surface of the threaded ring 27 with your hand, it is easier to push the threaded ring 27 to rotate and it is less likely to slip.

[0033] Reference Figure 2-4 As shown in this embodiment: a sealing ring 211 is fixedly connected to the outside of the flange at one end of the telescopic pipe 22. The sealing ring 211 is made of rubber. When the flange at one end of the telescopic pipe 22 is connected to the flange on one side of the water inlet pipe 4, the rubber sealing ring 211 will be fitted on the outside of the connection between the two flanges to further seal the outside of the connection and avoid sewage leakage as much as possible. A stop block 212 is fixedly connected to the end of the screw 25 away from the sliding rod 24. The length of the stop block 212 is greater than the diameter of the screw 25. By setting the stop block 212, the movement range of the threaded ring 27 on the outer surface of the screw 25 can be limited, and the threaded ring 27 can be prevented from falling off the surface of the screw 25 and being lost when it moves outward.

[0034] Reference Figure 1 , Figure 2 , Figure 3 , Figure 6 and Figure 7 As shown in this embodiment: the auxiliary device 3 includes two slot blocks 33, which are respectively fixed on both sides of the filter plate 26. A slider 35 is slidably connected to the inner wall of the slot block 33. A spring 34 is provided inside the slot block 33, and the slider 35 is installed on one end of the inner wall of the slot block 33 by the spring 34. Two rectangular slots 31 are opened on one side of the water inlet pipe 4. A slot 32 is opened on one end of the inner wall of the rectangular slot 31. When installing the filter plate 26, the slot blocks 33 on both sides of the filter plate 26 are aligned with the two rectangular slots 31 on one side of the water inlet pipe 4, and the slider 35 inside the two slot blocks 33 is controlled to fit against the outer surface of the water inlet pipe 4, thus pushing the filter. Plate 26 presses against slider 35, causing slider 35 to slide into the groove 33 and compress spring 34. After filter plate 26 is located on the inner wall of water inlet pipe 4, spring 34 returns to its original state and pushes slider 35 outward to insert one end of slider 35 into slot 32. Threaded ring 27 is then fixed to one side of water inlet pipe 4 to complete the installation. One side of groove 33 has a through groove, and one side of slider 35 has a groove 36. When filter plate 26 needs to be removed, push the groove 36 on the surface of slider 35 at the through groove on one side of groove 33 to more easily push slider 35 to move into groove 33. Then, pull filter plate 26 outward.

[0035] Working principle: When using the sewage treatment device, align the grooves 33 on both sides of the filter plate 26 with the two rectangular grooves 31 on one side of the inlet pipe 4. Control the sliders 35 inside the two grooves 33 to adhere to one side of the outer surface of the inlet pipe 4, push the filter plate 26 to squeeze the sliders 35, causing the sliders 35 to slide into the grooves 33 and compress the spring 34. After the filter plate 26 is located on the inner wall of the inlet pipe 4, the spring 34 returns to its original state and pushes the sliders 35 outward, inserting one end of the sliders 35 into the slot 32. Fix the threaded ring 27 to one side of the inlet pipe 4 to complete the installation. Move one end of the telescopic tube 22 so that one end of the telescopic tube 22... The expansion joint 22 is attached to one side of the inlet pipe 4. A flange connects one end of the expansion joint 22 to the inlet pipe 4. The threaded ring 27 on the outer surface of the screw 25 is rotated, causing the threaded ring 27 to move towards the grooved rod 23 on the outer surface of the screw 25, pushing the pressure block 28 to move. One side of the pressure block 28 is pressed against the outer surface of the grooved rod 23, fixing it in place against the sliding rod 24 and the expansion joint 22. The end of the round pipe 21 furthest from the expansion joint 22 is then connected to the sewage conveying pipeline via a flange. Sewage is then conveyed through the pipeline, passing through the round pipe 21, the expansion joint 22, and the inlet pipe 4, into the tank 1. Chemicals are added into the tank 1 through the dosing port 5 at the top of the tank 1. Adding flocculants and other agents enhances the treatment effect of sewage. When sewage passes through the filter screen 26, the filter screen on the outer surface of the filter screen 26 can block paper scraps and other debris in the sewage. The sewage undergoes sedimentation inside the tank (1), causing the solid particles inside the sewage to settle to the bottom of the tank (1), and then be discharged through the outlet pipe (6) on one side of the tank (1). Connect the pipe of the sludge pumping equipment to one end of the sewage pipe (7), and then open the control valve at the top of the sewage pipe (7) to pump out the sludge inside the tank (1). When it is necessary to clean the filter screen on the surface of the filter screen 26, rotate the thread on both sides of the round pipe 21 respectively. Ring 27 causes the threaded ring 27 to move the pressure block 28 away from the outer surface of the groove rod 23, thus releasing the position fixation of the sliding rod 24. Then, the connection between the telescopic tube 22 and the water inlet pipe 4 is released, pushing the telescopic tube 22 to retract and causing the sliding rod 24 to slide on the inner wall of the groove rod 23 toward the round tube 21. This allows the water inlet pipe 4 and the filter plate 26 to be cleaned without removing the sewage conveying pipe connected to one end of the round tube 21. Pushing the groove 36 on the surface of the slider 35 at the through groove on one side of the groove block 33 makes it easier to push the slider 35 to move into the groove block 33. Then, the filter plate 26 can be removed and cleaned by pulling it outward.
