Description

Technical Field

[0001] The utility model relates to the technical field of water treatment, in particular to an automatic pressure reducing device for a chemical dosing device. Background Technique

[0002] In order to avoid pollution to the surrounding environment caused by direct discharge of sewage, it is necessary to treat the discharged sewage. Usually, when treating sewage, drugs need to be added to the sewage. The drugs include polyaluminum chloride, polyaluminum ferric chloride, basic aluminum chloride, polyacrylamide, activated carbon and various filter materials, etc.

[0003] When dosing in the chemical dosing device, most of them pressurize the inside of the chemical dosing device to press the drug into the water treatment tank. However, in order to prevent the gas emitted during sewage treatment from overflowing, both the chemical dosing device and the water treatment tank need to be sealed, which also causes the internal pressure of the chemical dosing device to increase easily when the chemical dosing device conveys the drug. If the pressure cannot be discharged in time, it is easy to cause damage to the chemical dosing device. Content of the Utility Model

[0004] The purpose of the utility model is to solve the above-mentioned disadvantages existing in the prior art, and to propose an automatic pressure reducing device for a chemical dosing device.

[0005] In order to achieve the above purpose, the utility model adopts the following technical scheme: design an automatic pressure reducing device for a chemical dosing device, including a mounting base.

Specific embodiments

[0024] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments.

[0025] Refer to Figures 1-6 , an automatic pressure reducing device for a dosing device, including a mounting seat 1, and mounting holes are respectively opened at the corners of the mounting seat 1. As Figure 6 shown, it is used to take bolts through the mounting holes to mount the mounting seat 1 on the dosing device.

[0026] At one end of the top of the mounting seat 1, there is a buffer box 2 with an open bottom. The buffer box 2 penetrates through the mounting seat 1. After the buffer box 2 is mounted on the dosing device, the buffer box 2 can be communicated with the dosing device;

[0027] As Figure 3 and Figure 4 shown, a lifting seat 3 is arranged in the buffer box 2. The lifting seat 3 is arranged in the first frame 4, and a rubber ring 5 is installed along the edge of the first frame 4. The rubber ring 5 is in close contact with the inner wall of the buffer box 2. A plurality of guide shafts 6 are vertically installed on the top of the lifting seat 3. The top of the guide shaft 6 is placed in the guide sleeve 7, and the top of the guide sleeve 7 is fixed to the top inside the buffer box 2. A compression spring 8 is also sleeved on the guide shaft 6. One end of the compression spring 8 is fixed on the lifting seat 3 and the other end is fixed on the guide sleeve 7; and an air outlet 13 is opened on one side of the buffer box 2, and the air outlet 13 is located above the lifting seat 3. When the pressure inside the dosing device increases, the increased-pressure gas at this time will pass through the bottom of the buffer box 2 and act on the bottom of the lifting seat 3. When the acting impact force is greater than the gravity of the lifting seat 3 and the elastic force of the compression spring 8, it will push the lifting seat 3 to slide upward along the inner wall of the buffer box 2. As the pressure inside the dosing device continues to increase, the lifting seat 3 will continuously rise and cross the air outlet 13, so that the air outlet 13 can be communicated with the dosing device, thereby discharging the excess gas, and thus realizing the operation of automatic pressure reduction;

[0028] It should be noted that in the actual use process, the lifting seat 3 is a straight plate. An opening 10 is provided on the side of the buffer box 2 away from the air outlet 13, and a sealing door 11 is hinged on one side of the opening 10. The other side of the sealing door 11 is connected to the buffer box 2 through a lock. The sealing door 11 can be opened to add counterweight blocks on the lifting seat 3 to increase the weight of the lifting seat 3. In this way, the critical pressure value for lifting the lifting seat 3 can be adjusted according to the usage conditions and surrounding environment of the dosing device, so as to improve the adaptability of the automatic pressure relief device. A rectangular limiting plate 9 is installed on the top of the lifting seat 3, and the guide shaft 6 is arranged outside the limiting plate 9 to limit the placement position of the counterweight block to prevent the added counterweight block from affecting the telescopic movement of the guide shaft 6 in the guide sleeve 7.

[0029] Furthermore, when the mounting seat 1 is fixed on the dosing device, a sealing gasket 12 is provided along the outer side of the bottom of the buffer box 2. The sealing gasket 12 is fixed on the bottom of the mounting seat 1. After the buffer box 2 extends into the dosing device, the connection between the buffer box 2 and the dosing device is sealed to ensure the normal use of the automatic pressure relief device.

[0030] As Figure 4 and Figure 5 shown, an exhaust gas treatment box 15 is provided on the side of the buffer box 2. The exhaust gas treatment box 15 is fixed on the mounting seat 1, and an air inlet 16 is provided at one end of the exhaust gas treatment box 15. The air inlet 16 is connected to the air outlet 13 through a connecting pipe 14. The gas discharged during pressure relief will enter the exhaust gas treatment box 15 through the connecting pipe 14. An exhaust pipe 23 is provided at the end of the exhaust gas treatment box 15 away from the air inlet 16, and several activated carbon plates 19 are provided inside the exhaust gas treatment box 15. The activated carbon plates 19 are arranged in the second frame 18, and the second frame 18 is in intermittent fit with the inner wall of the exhaust gas treatment box 15. The gas entering the exhaust gas treatment box 15 will pass through multiple layers of activated carbon plates 19 and be discharged from the exhaust pipe 23. In this way, the activated carbon plates 19 can purify the gas to ensure the safe discharge of the gas. Several slots 21 are provided on the top of the exhaust gas treatment box 15. The slots 21 correspond to the second frame 18 one by one, and the top of the second frame 18 passes through the slots 21 and is installed with a cover plate 20. The cover plate 20 is fixed to the exhaust gas treatment box 15 through fasteners. During the use process, the fasteners are one of bolts and screws. A handle 22 is installed on the top of the cover plate 20. When the activated carbon plates 19 are saturated and need to be replaced, the fasteners on the cover plate 20 can be unscrewed, and then the handle 22 is held to lift and remove the activated carbon plates 19 from the exhaust gas treatment box 15 to facilitate the replacement of the activated carbon plates 19 and ensure the gas treatment effect of the activated carbon plates 19.

[0031] It should be noted that on both sides of the second frame 18, there are limit seats 17 arranged along the edge of the second frame 18. The limit seats 17 are fixed on the inner wall of the waste gas treatment box 15 to limit the second frame 18, so as to ensure the stability of the activated carbon plate 19 in the waste gas treatment box 15.

[0032] The above is only the preferred specific implementation manner of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution and the inventive concept of the present utility model, makes equivalent replacements or changes, and should be covered by the protection scope of the present utility model.
