Description

Technical Field

[0001] This utility model relates to the field of wastewater system dosing blockage technology, specifically a device for preventing wastewater system dosing blockage. Background Technology

[0002] A wastewater treatment system is an integrated system composed of several unit processes for treating wastewater. Treatment targets are typically determined based on the size and properties of the particles to be removed (referred to as particle size distribution).

[0003] The original wastewater dosing system used a rubber conveyor belt to transport the chemicals to the top of the triplet tank. The chemicals fell directly into the triplet tank from the tail end of the belt. During the process of transporting the chemicals, the hot air inside the triplet tank at the tail end of the conveyor belt would back up, causing the belt to become damp. The chemicals would then stick to the belt when they came into contact with the moisture, causing spillage and frequent belt deviation. Moreover, the hot air back up from the triplet tank at the tail end of the belt would cause frequent blockages at the dispensing port, affecting the continuous operation of the wastewater dosing system and posing certain environmental risks. Utility Model Content

[0004] The purpose of this invention is to provide a device to prevent blockage in wastewater dosing systems, addressing the aforementioned issues in the original wastewater dosing system. This device uses a rubber conveyor belt to transport chemicals to the top of a three-compartment tank, with the chemicals falling directly from the belt's tail end into the tank. During this process, the conveyor belt becomes damp due to the backflow of hot air from the tank's tail end, causing the chemicals to stick and spill, and resulting in frequent belt misalignment. Furthermore, the backflow of hot air from the tank causes frequent blockages at the chemical inlet at the belt's tail end, affecting the continuous operation of the wastewater dosing system and posing certain environmental risks.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a device for preventing blockage of chemical dosing in a wastewater system, comprising a three-compartment tank, wherein a clamping assembly for fixing a chemical dosing feed pipe is provided at the upper end of the inlet of the three-compartment tank, a dosing assembly for dosing chemicals in the wastewater system is provided on the clamping assembly, an air supply assembly for preventing hot air backflow in the three-compartment tank is provided on the dosing assembly, a purification assembly for absorbing and purifying the hot air in the three-compartment tank is provided on one side of the three-compartment tank, the purification assembly is located at the lower end of the dosing assembly and around the dosing assembly, and a spraying assembly for recovering heat from the hot air is provided on the purification assembly.

[0006] Preferably, the clamping assembly includes a base disposed on one side of the triple box, a support rod fixedly installed on the upper end of the base, two connecting rods fixedly installed on one end of the support rod, a first arc-shaped clamp fixedly installed on one end of each of the two connecting rods, a second arc-shaped clamp being inserted and connected to one end of the first arc-shaped clamp by a screw, and a nut being threaded on the axial sidewall of the screw.

[0007] Preferably, the dosing assembly includes a discharge pipe between a first arc-shaped clamp and a second arc-shaped clamp. A flared mouth is fixedly installed at the upper end of the discharge pipe. A first chamber is opened on the discharge pipe. A threaded rail is fixedly installed in the first chamber. A reducing head is welded to the lower end of the discharge pipe.

[0008] Preferably, the air supply assembly includes three aeration air ducts fixedly installed on the side wall of the material discharge pipe. The three aeration air ducts are evenly distributed at 120 degrees on the axial side wall of the material discharge pipe. Each of the three aeration air ducts is provided with a valve on its axial side wall and a ball valve on its ball valve.

[0009] Preferably, the purification assembly includes two fixed rods fixedly installed on both sides of the three-unit box, an air intake box fixedly installed between the two fixed rods, two limiting rods provided on one side of the three-unit box, a purification box fixedly installed between the two limiting rods, an air intake pipe fixedly installed between the purification box and the air intake box, a second chamber opened on the purification box, an activated carbon plate provided on the second chamber, and an exhaust pipe fixedly installed on one side of the purification box.

[0010] Preferably, the spraying assembly includes a water tank fixedly installed on the purification box, a third chamber opened in the water tank, a piston inserted through the water tank, a water pump installed in the third chamber, a drain pipe fixedly installed at the drain end of the water pump, the drain pipe passing through the purification box, two arc-shaped baffles fixedly installed on the third chamber, and a heat recovery pipe fixedly installed at the lower end of the purification box.

[0011] Preferably, the heat recovery pipe is located between two arc-shaped baffles.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. With the cooperation of screws, nuts, drop tube, first arc clamp and second arc clamp, the influence of hot air on the drop tube is reduced by adjusting the distance between the drop tube and the triple box. The use of threaded rail can also reduce the influence of hot air on the upper end of the drop tube. Then, the valve on the aeration air pipe is opened to allow airflow to enter the drop tube through the aeration air pipe. This not only increases the feeding rate but also pushes the hot air back. The air volume of the aeration air pipe can be adjusted by the ball valve to meet the requirements.

[0014] 2. Hot air is drawn into the purification chamber through the suction box and suction pipe. The activated carbon plate adsorbs harmful substances in the hot air. The purified hot air is then discharged into the atmosphere through the exhaust pipe to avoid air pollution and reduce the amount of hot air entering the discharge pipe, which could cause blockage. At this time, the water pump is started to discharge water in the water tank into the second chamber through the drain pipe. The water then comes into contact with the hot air and heats the water through heat transfer. The heat is then recovered through the heat recovery pipe to avoid heat waste.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Example 1: Please refer to Figures 1-3A device for preventing blockage of chemical dosing in a wastewater system includes a triplet 1. A clamping assembly 2 for fixing a chemical dosing feed pipe is provided at the upper end of the inlet of the triplet 1. A dosing assembly 3 for dosing chemicals in the wastewater system is provided on the clamping assembly 2. An air supply assembly 4 for preventing hot air from flowing back into the triplet 1 is provided on the dosing assembly 3. A purification assembly 5 for absorbing and purifying the hot air in the triplet 1 is provided on one side of the triplet 1. The purification assembly 5 is located at the lower end of the dosing assembly 3 and around the dosing assembly 3. A spraying assembly 6 for recovering heat from the hot air is provided on the purification assembly 5.

[0022] The clamping assembly 2 includes a base 21 disposed on one side of the triple box 1. A support rod 22 is fixedly installed on the upper end of the base 21. Two connecting rods 23 are fixedly installed on one end of the support rod 22. A first arc-shaped clamp 24 is fixedly installed on one end of each of the two connecting rods 23. A second arc-shaped clamp 26 is inserted and connected to one end of the first arc-shaped clamp 24 by a screw 25. A nut 27 is threaded on the axial side wall of the screw 25.

[0023] The dosing assembly 3 includes a discharge pipe 31 between a first arc-shaped clamp 24 and a second arc-shaped clamp 26. The discharge pipe 31 has a diameter of 89 mm. A flared mouth 32 is fixedly installed at the upper end of the discharge pipe 31. The flared mouth 32 can prevent the drug from being spilled everywhere during dispensing. A first chamber 33 is opened on the discharge pipe 31. A threaded track 34 is fixedly installed in the first chamber 33. The threaded track 34 can prevent heat from heating the inner wall of the discharge pipe 31, so that the drug adheres to the inner wall of the discharge pipe 31. A reducing head 35 is welded to the lower end of the discharge pipe 31. The reducing head 35 increases the diameter from 89 mm to 159 mm, thereby increasing the dispensing speed.

[0024] The air supply assembly 4 includes three aeration air ducts 41 fixedly installed on the side wall of the discharge pipe 31. The three aeration air ducts 41 are evenly distributed at 120 degrees on the axial side wall of the discharge pipe 31. The diameter of the aeration air ducts 41 is 25 mm. Each of the three aeration air ducts 41 is provided with a valve 42 and a ball valve 43. The air volume of the aeration air ducts 41 can be adjusted by the valves 42 and the ball valves 43.

[0025] In this embodiment: During the processing of the triple box 1, a lot of hot air is generated. The hot air enters the discharge pipe 31, thereby heating the powder and causing it to adhere to the inner wall of the discharge pipe 31, which can easily cause blockage. Therefore, the discharge pipe 31 is first fixed between the first arc-shaped clamp 24 and the second arc-shaped clamp 26 by screws 25 and nuts 27, thereby adjusting the distance between the discharge pipe 31 and the triple box 1 to reduce the impact of hot air on the discharge pipe 31. The use of threaded rails 34 can also reduce the impact of hot air on the upper end of the discharge pipe 31. Then, the valve 42 on the aeration air pipe 41 is opened to allow airflow to enter the discharge pipe 31 through the aeration air pipe 41. This not only increases the discharge rate but also pushes the hot air back. The air volume of the aeration air pipe 41 can be adjusted by ball valve 43 to meet the requirements.

[0026] Example 2: This example is an improvement on Example 1. For details, please refer to [link / reference]. Figure 4 The purification component 5 includes two fixed rods 51 fixedly installed on both sides of the triple box 1, an air intake box 52 fixedly installed between the two fixed rods 51, two limiting rods 53 provided on one side of the triple box 1, a purification box 54 fixedly installed between the two limiting rods 53, an air intake pipe 55 fixedly installed between the purification box 54 and the air intake box 52, the air intake pipe 55 and the purification box 54 are connected, the air intake pipe 55 and the air intake box 52 are connected, a second chamber 56 is opened on the purification box 54, an activated carbon plate 57 is provided on the second chamber 56, and an exhaust pipe 58 is fixedly installed on one side of the purification box 54.

[0027] The spraying assembly 6 includes a water tank 61 fixedly installed on the purification box 54. A third chamber 62 is opened on the water tank 61. A piston 63 is inserted and connected to the water tank 61. A water pump 64 is installed on the third chamber 62. A drain pipe 65 is fixedly installed at the drain end of the water pump 64. The drain pipe 65 passes into the purification box 54. Two arc-shaped baffles 66 are fixedly installed on the third chamber 62. A heat recovery pipe 67 is fixedly installed at the lower end of the purification box 54.

[0028] The heat recovery pipe 67 is located between two arc-shaped baffles 66, which can block the water that has absorbed heat and prevent the water from flowing onto the activated carbon plate 57, thereby affecting the adsorption efficiency of the activated carbon plate 57.

[0029] In this embodiment: If the hot gas generated during processing in the triple-compartment box 1 is directly discharged into the atmosphere, it will cause air pollution. At this time, the hot gas is drawn into the purification box 54 through the suction box 52 and the suction pipe 55. The activated carbon plate 57 can adsorb the harmful substances in the hot gas. Then, the purified hot gas is discharged into the atmosphere through the exhaust pipe 58 to avoid air pollution. It can also reduce the amount of hot gas entering the discharge pipe 31, which would cause the discharge pipe 31 to become blocked. At this time, the water pump 64 is started to discharge the water in the water tank 61 into the second chamber 56 through the drain pipe 65. Then, the water comes into contact with the hot gas and heats the water through heat transfer. Then, the water is recovered through the heat recovery pipe 67, thereby recovering the heat and avoiding heat waste.
