Description

Technical Field

[0001] This utility model belongs to the field of environmental protection equipment technology, specifically relating to a ventilation device for a leachate collection tank. Background Technology

[0002] As a core facility for urban solid waste treatment, waste-to-energy plants generate a large amount of leachate during operation. This leachate has a complex composition, containing high concentrations of organic matter, heavy metals, and ammonia nitrogen, which have strong biological toxicity and environmental hazards. The anaerobic decomposition of organic matter in the leachate produces a large amount of flammable, explosive, and toxic gases. If not properly treated, it can cause serious environmental pollution. Leachate collection ponds must be equipped with ventilation equipment to control gas concentrations and prevent explosions or poisoning accidents.

[0003] However, traditional ventilation equipment typically uses simple exhaust fans for ventilation, and filters toxic and harmful substances in the air through filter components in the exhaust system. However, when the filter components reach saturation, the system needs to be shut down for replacement. During the replacement, it is impossible to filter harmful gases emitted from the leachate collection tank, which causes considerable inconvenience to users. Therefore, the applicant proposes a ventilation device for leachate collection tanks to solve the above problems. Utility Model Content

[0004] The purpose of this utility model is to provide a ventilation device for a leachate collection tank, which can easily switch the air circulation channel with one click when the filter plate needs to be replaced, and can continuously filter harmful gases emitted by the collection tank body. No shutdown operation is required during filter plate replacement, which brings more convenience to the user.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A ventilation device for a leachate collection tank, comprising:

[0007] The collection pool body and the suction mechanism mounted on the top of the collection pool body, the filter mechanism mounted on the top of the suction mechanism and the switching mechanism mounted between the suction mechanism and the filter mechanism;

[0008] The suction mechanism includes a suction hood fixedly installed on the top of the collection pool body, a housing fixedly installed on the top of the suction hood, and a first air outlet and a second air outlet respectively opened on the top of the housing.

[0009] The filtration mechanism includes a filter box fixedly installed on the top of the chassis. The filter box has a first filter chamber and a second filter chamber respectively. The bottom of the first filter chamber has a first pair of interfaces corresponding to the first air outlet, and the bottom of the second filter chamber has a second pair of interfaces corresponding to the second air outlet.

[0010] The switching mechanism includes a rotating rod rotatably installed between the filter box and the housing. A connecting pipe is fixedly installed on one side of the rotating rod, and a sealing cover is fixedly installed on the other side of the rotating rod.

[0011] Preferably, a fan wheel is rotatably installed inside the casing, and the casing and the air intake hood are interconnected.

[0012] Preferably, a motor is fixedly installed at the rear end of the chassis, and the output shaft of the motor is fixedly connected to the impeller.

[0013] Preferably, a second track frame for sliding the connecting pipe and the sealing cover is fixedly installed on the top of the chassis, and a first track frame for sliding the connecting pipe and the sealing cover is fixedly installed on the bottom of the filter box.

[0014] Preferably, filter plates are slidably installed inside both the first and second filter chambers, and a handle is fixedly installed on one side of each filter plate.

[0015] Preferably, the top of the filter box is connected to an air collecting hood, and the top of the air collecting hood is connected to an exhaust pipe.

[0016] Preferably, the filter box is fixedly installed to the chassis via a fixing bracket, and an operating handle is fixedly installed on one side of the rotating rod.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] (1) This utility model is equipped with a filter mechanism and a switching mechanism that work together. When the connecting pipe is connected to the first filter chamber, the harmful gas emitted from the collection tank body can be introduced into the first filter chamber for filtration and exhaust. When the filter plate in the first filter chamber is saturated, the connecting pipe can be rotated to the second filter chamber with one key by operating the rotating rod. This allows the harmful gas to be switched to the second filter chamber for continued exhaust and filtration. This allows personnel to replace the filter plate in the first filter chamber and switch between them easily. There is no need to stop the machine during the replacement of the filter plate, which brings more convenience to the user.

[0019] (2) This utility model is equipped with a sealing cover, which can be switched so that the sealing cover can move in the opposite direction and cover the first air outlet or the second air outlet to seal it. This allows the harmful air drawn into the casing to be introduced to the position of the connecting pipe, which is convenient for introducing the harmful air into the filter chamber corresponding to the connecting pipe for filtration, thus improving the performance.

[0030] Example 1:

[0031] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, a ventilation device for a leachate collection tank includes:

[0032] The collection pool body 4 and the suction mechanism 3 mounted on the top of the collection pool body 4, the filter mechanism 1 mounted on the top of the suction mechanism 3 and the switching mechanism 2 mounted between the suction mechanism 3 and the filter mechanism 1.

[0033] The suction mechanism 3 includes a suction hood 36 fixedly installed on the top of the collection tank body 4. A housing 31 is fixedly installed on the top of the suction hood 36. A first air outlet 32 ​​and a second air outlet 33 are respectively opened on the top of the housing 31.

[0034] The filter mechanism 1 includes a filter box 11 fixedly installed on the top of the chassis 31. The filter box 11 has a first filter chamber 110 and a second filter chamber 111 respectively. The bottom of the first filter chamber 110 has a first interface 17 corresponding to the first air outlet 32, and the bottom of the second filter chamber 111 has a second interface 18 corresponding to the second air outlet 33.

[0035] The switching mechanism 2 includes a rotating rod 22 rotatably installed between the filter box 11 and the housing 31. A connecting pipe 21 is fixedly installed on one side of the rotating rod 22, and a sealing cover 24 is fixedly installed on the other side of the rotating rod 22.

[0036] As can be seen from the above, the leachate generated during the operation of the waste incineration power plant is introduced into the collection tank body 4 for collection and storage. The suction force generated by the casing 31 can be used to easily draw the harmful air emitted from the collection tank body 4 into the casing 31 through the suction hood 36. When the connecting pipe 21 corresponds with the first connecting port 17 and the first air outlet 32, the first filter chamber 110 can be connected to the casing 31, so that the harmful air in the casing 31 can be introduced into the first filter chamber 110 through the connecting pipe 21, which can facilitate the filtration and purification of harmful substances in the harmful air.

[0037] By rotating the rotating rod 22, the connecting pipe 21 can be easily rotated 180°, allowing it to align with the second connecting port 18 and the second air outlet 33. Simultaneously, the sealing cover 24 can be rotated 180° in the opposite direction, covering and sealing the first air outlet 32. This allows harmful air from the casing 31 to be introduced into the connecting pipe 21 through the second air outlet 33, facilitating its entry into the second filter chamber 111 for filtration. This enables continuous exhaust filtration of harmful air, allowing personnel to maintain and replace the filter media in the first filter chamber 110 without stopping the machine, thus providing greater convenience for users.

[0038] Depend on Figure 5 It can be seen that the fan wheel 35 is rotatably installed inside the casing 31, and the casing 31 and the air intake hood 36 are interconnected.

[0039] As can be seen from the above, the rotation of the impeller 35 can easily draw air into the casing 31, and the suction hood 36 can cover the top of the collection pool body 4, so that the emitted harmful air can be drawn into the casing 31.

[0040] For details, please refer to Figure 2 and Figure 5 As shown, the motor 5 is fixedly installed at the rear end of the casing 31, and the output shaft of the motor 5 is fixedly connected to the impeller 35.

[0041] As can be seen from the above, the motor 5 can provide power to the wind turbine 35, which can easily drive the wind turbine 35 to rotate.

[0042] For details, please refer to Figure 2 , Figure 5 and Figure 6 As shown, a second track frame 34 for sliding the connecting pipe 21 and the sealing cover 24 is fixedly installed on the top of the casing 31, and a first track frame 16 for sliding the connecting pipe 21 and the sealing cover 24 is fixedly installed on the bottom of the filter box 11.

[0043] As can be seen from the above, the first track frame 16 and the second track frame 34 can conveniently limit the sealing cover 24 and the connecting pipe 21, so that the sealing cover 24 and the connecting pipe 21 can slide and rotate along the first track frame 16 and the second track frame 34, avoiding shaking.

[0044] Example 2:

[0045] refer to Figure 4 As shown, filter plates 12 are slidably installed inside the first filter chamber 110 and the second filter chamber 111, and a handle 13 is fixedly installed on one side of the filter plate 12.

[0046] As can be seen from the above, by inserting the filter plate 12 into the first filter chamber 110 and the second filter chamber 111, the multi-layer arrangement can facilitate multiple filtration and purification of harmful air, effectively removing harmful substances in the air and avoiding pollution of the external air environment. The filter plate 12 can be easily pulled out by using the handle 13, which is convenient for maintenance and replacement.

[0047] refer to Figure 4 As shown, the top of the filter box 11 is connected to an air collecting hood 19, and the top of the air collecting hood 19 is connected to an exhaust pipe 15.

[0048] As can be seen from the above, the air filtered by the first filter chamber 110 and the second filter chamber 111 is introduced into the air collection hood 19 for collection, and the filtered and purified air can be discharged through the exhaust pipe 15.

[0049] refer to Figure 1 , Figure 3 and Figure 6 As shown, the filter box 11 is fixedly installed to the housing 31 by a fixing bracket 14, and an operating handle 23 is fixedly installed on one side of the rotating rod 22.

[0050] As can be seen from the above, the filter box 11 can be easily supported by the fixing frame 14, and the rotating rod 22 can be easily rotated by holding the operating handle 23, which can easily operate the connecting pipe 21 to rotate 180°, and can easily switch the connecting pipe 21 with one button, bringing more convenience to the user.
