Description

Technical Field

[0001] The utility model belongs to the technical field of rectangular pool body shields, and more specifically relates to an odor sealing structure for a rectangular pool body. Background Art

[0002] In the design of sewage treatment plants, rectangular hydraulic structures are commonly used structural forms, such as rectangular aerated grit chambers and sedimentation tanks. In the sewage treatment process, odor is easily generated and dissipated to the outside of the tank and the surrounding environment, causing large-scale air pollution and seriously affecting the quality of the surrounding environment. Odor control has received more and more attention. The primary task of odor control is to control the dissipation of odor from the collection level.

[0003] Because a bridge car that can reciprocate along the length of the tank body is usually installed on the top of the traditional aerated grit tank or rectangular sedimentation tank, and the sand discharge pipe or mud discharge pipe (hereinafter referred to as: bridge car accessory) installed on the bridge car connects the inside and outside of the tank body and moves synchronously with the bridge car, it is difficult to close the tank body independently. The usual practice is to close the structure as a whole and then collect and treat the odor.

[0004] However, the overall closed solution has many disadvantages:

[0005] 1. Due to the corrosiveness of the gas, it is very easy to cause corrosion of the equipment enclosed inside, thus affecting the operating stability of the entire sewage treatment equipment and control system.

[0006] 2. The overall enclosed structure has a large span and a heavy structure, requiring the original sewage treatment facility to have a large structural bearing capacity, resulting in high costs for the overall enclosed structure, large floor space, and possible impact on the structural safety of the original sewage treatment facility, and high investment in structural construction.

[0007] 3. The overall enclosed method forms a confined space after closure, which increases the difficulty of safety management of maintenance and operation management operations.

[0008] 4. The concentration of harmful gases in the overall enclosed space is high. When the operators of the sewage treatment plant enter the enclosed space, there is a great risk to their personal safety, so it is usually necessary to install gas detection equipment, which also increases the cost of closure. The operation and maintenance of the gas detection equipment also increases the operating cost of the overall deodorization system.

[0009] 5. The enclosed space of the overall enclosed method is large. According to the requirements of the ventilation ratio of general workshops, the ventilation volume is 6-8 times the space volume. The ventilation volume is large. All the odors discharged must be treated, which greatly increases the design scale of the subsequent deodorization system and the investment in the deodorization system. Moreover, due to the dilution effect caused by ventilation, the concentration of odor collected by the subsequent deodorization system is very low, which greatly reduces the operation effect of the odor treatment system.

[0010] 6. The lifting of large equipment in a closed space is difficult due to the overall closed structure, resulting in increased costs for equipment maintenance and lifting.

[0011] Therefore, it is necessary to design a new pool body sealing solution to replace the overall sealing. Utility Model Content

[0012] The utility model aims to provide an odor sealing structure for a rectangular pool body in view of the deficiencies in the prior art, so as to solve the problems of the existing fully sealed solution, such as high cost, large occupied area, corrosion to the original facility structure and threat to the safety of the staff.

[0013] In order to achieve the above object, the utility model provides an odor sealing structure for a rectangular pool body, comprising:

[0014] A cover plate, the cover plate is used to cover the rectangular pool body;

[0015] A movable seam is provided on the cover plate, and an elastic seal and a movable block are provided in the movable seam. The elastic seal can seal the movable seam or cooperate with the movable block to seal the movable seam. The bridge vehicle accessory parts vertically pass through the movable block, and can drive the movable block to move axially along the movable seam.

[0016] Optionally, a protrusion for supporting the elastic sealing member is provided at the lower end of the movable seam.

[0017] Optionally, the elastic sealing member comprises:

[0018] A first elastic block and a second elastic block, wherein the first elastic block and the second elastic block can jointly block the movable gap, and the movable block is movably arranged in the gap between the first elastic block and the second elastic block.

[0019] Optionally, the first elastic block is a capsule filled with compressible gas or liquid.

[0020] Optionally, the bladder is connected to a pressure gauge, a pressure relief valve and a one-way valve.

[0021] Optionally, the cross-section of the capsule is circular or elliptical, the horizontal cross-section of the moving block is shuttle-shaped, and the vertical cross-section is hourglass-shaped that gradually expands toward the upper and lower ends.

[0022] Optionally, a roller cooperating with the capsule is arranged on the side wall of the moving block.

[0023] Optionally, one end of the moving block is exposed at the movable seam.

[0024] Optionally, when the balloon is filled with gas, the input end of the one-way valve is further provided with a gas source triplet.

[0025] Optionally, when the bladder is filled with liquid, the liquid is antifreeze liquid.

[0026] The utility model provides an odor sealing structure for a rectangular pool body, and its beneficial effects are:

[0027] The closed structure reduces odor emission by covering the pool with a cover plate, which is conducive to the centralized collection and treatment of odor. The movable seam is adapted to the mobile use of the bridge vehicle. When in use, the bridge vehicle's bridge vehicle accessories pass through the movable seam, and the part interlaced with the movable seam is connected to the moving block, and then the movable seam part is blocked by an elastic seal, and a part of the elastic seal cooperates with the movable seam to block the movable seam. The elastic deformation of the elastic seal is used to ensure the sealing effect during the movement of the moving block, and avoid the odor emission caused by the movement of the bridge vehicle. By closing the pool separately, the shortcomings of the overall closure can be overcome, so that the odor generated by the sewage in the pool can be collected at a lower cost, which greatly reduces the design scale of the subsequent odor treatment system, reduces investment, and reduces operation and management costs. Compared with the overall closure method, it is greatly reduced. At the same time, the management and safety management of personnel safety, facilities, equipment, and safety management are almost the same as before the installation of the separate closed equipment.

[0036] The preferred embodiments of the present invention will be described in more detail below. Although the preferred embodiments of the present invention are described below, it should be understood that the present invention can be implemented in various forms and should not be limited by the embodiments described herein. On the contrary, these embodiments are provided to make the present invention more thorough and complete, and to fully convey the scope of the present invention to those skilled in the art.

[0037] like Figure 1-4 As shown, an odor sealing structure for a rectangular pool body comprises:

[0038] Cover plate 1, cover plate 1 is used to cover the rectangular pool body;

[0039] The movable seam is arranged on the cover plate 1, and an elastic seal and a movable block 2 are arranged in the movable seam. The elastic seal can seal the movable seam or cooperate with the movable block 2 to seal the movable seam. The bridge vehicle accessories vertically pass through the movable block 2, and can drive the movable block 2 to move axially along the seam.

[0040] Specifically, the pool is sealed by the cover plate 1 to reduce the odor emission, which is conducive to the centralized collection and treatment of odor. The movable seam is adapted to the mobile use of the bridge vehicle. When in use, the bridge vehicle accessory 9 of the bridge vehicle passes through the movable seam, and the part interlaced with the movable seam is connected to the moving block 2, and then a part of the movable seam is sealed by the elastic seal, and a part of the elastic seal cooperates with the movable seam to seal. The elastic deformation of the elastic seal is used to ensure the sealing effect during the movement of the moving block 2, and avoid the odor emission caused by the movement of the bridge vehicle. By using the method of separate sealing in the pool, the shortcomings of the overall sealing can be overcome, so that the odor generated by the sewage in the pool can be collected at a lower cost, which greatly reduces the design scale of the subsequent odor treatment system, reduces investment, and greatly reduces the operation and management costs compared to the overall sealing method. At the same time, the management and safety management of personnel safety, facilities, equipment, and safety management are almost the same as before the installation of the separate sealing equipment.

[0041] Furthermore, an odor collecting device is connected to the cover plate 1. The cover plate 1 can be in one piece or in a spliced ​​form, and in the case of the spliced ​​form, the splicing seam can be a movable seam.

[0042] In this embodiment, a protrusion for supporting the elastic sealing member is provided at the lower end of the movable seam.

[0043] Specifically, the elastic sealing member is supported by the raised portion to prevent the elastic sealing member from sagging and deforming due to gravity, thereby affecting the sealing effect.

[0044] In this embodiment, the elastic sealing member comprises:

[0045] The first elastic block 3 and the second elastic block 4 can jointly block the movable gap, and the moving block 2 is movably arranged in the gap between the first elastic block 3 and the second elastic block 4 .

[0046] Specifically, the first elastic block 3 and the second elastic block 4 jointly squeeze the moving block 2 from both sides, thereby ensuring a sealing effect during the movement of the moving block 2 .

[0047] In this embodiment, the first elastic block 3 is a capsule filled with compressible gas or liquid.

[0048] Specifically, elasticity is provided by compressible gas or liquid. Compared with a solid elastic body, not only is the fluidity of the liquid and gas better, but also the track gap of the moving block 2 cannot be closed in time due to the movement of the moving block 2.

[0049] Furthermore, the second elastic block 4 is also a capsule, which can be a single-layer structure or a multi-layer structure, but must meet the requirements of gas corrosion resistance and ultraviolet resistance, and a flexible material with a certain structural strength is selected so that the shape of the capsule will not produce uneven deformation and affect the sealing effect. The part in contact with the shuttle device is reinforced with wear-resistant flexible materials, such as corrosion-resistant rubber, to avoid damage to the capsule during long-term operation.

[0050] In this embodiment, the bladder is connected to a pressure gauge 7 , a pressure relief valve 6 and a one-way valve 5 .

[0051] Specifically, gas or liquid is added through the one-way valve 5, and the pressure of the bladder is monitored through the pressure gauge 7. It can be used in conjunction with a pressure limiting device, and safe pressure relief is performed through the pressure relief valve 6 or other pressure relief devices.

[0052] In this embodiment, the cross section of the capsule is circular or elliptical, the horizontal cross section of the moving block 2 is shuttle-shaped, and the vertical cross section is hourglass-shaped that gradually expands toward the upper and lower ends.

[0053] Specifically, the hourglass-shaped side surface and the circular or elliptical capsule body cooperate to form at least one contact sealing surface / line to ensure the sealing effect.

[0054] In this embodiment, a roller 8 cooperating with the capsule is arranged on the side wall of the moving block 2 .

[0055] Specifically, the moving resistance of the moving block 2 is reduced by the roller 8 .

[0056] In this embodiment, one end of the moving block 2 is exposed at the movable seam.

[0057] Specifically, the movable block 2 is exposed to facilitate confirmation of the position of the movable block 2 and facilitate maintenance and positioning.

[0058] In this embodiment, when the balloon is filled with gas, the input end of the one-way valve 5 is further provided with a gas source triplet.

[0059] Specifically, the gas is filtered through the gas source triplex.

[0060] In this embodiment, when the bladder is filled with liquid, the liquid is antifreeze liquid.

[0061] Specifically, it is filled with antifreeze liquid to avoid freezing in winter.

[0062] In this embodiment, a rectangular sewage pool is used as an example of an odor sealing structure for a rectangular pool body;

[0063] The cover plate 1 is horizontally arranged on the sewage pool, and the movable seam is also horizontally arranged. The first elastic block 3 and the second elastic block 4 are cylindrical, respectively, and the shuttle-shaped movable block 2 is movably connected in the gap between the first elastic block 3 and the second elastic block 4. By utilizing the shuttle-shaped shape to adapt to the deformation curve of the first elastic block 3 and the second elastic block 4 after being squeezed, it is ensured that it can be tightly closed during the movement process, meeting the movement of the bridge vehicle while preventing the escape of odor.

[0064] The various embodiments of the utility model have been described above, and the above description is exemplary, not exhaustive, and is not limited to the disclosed embodiments. Many modifications and changes are obvious to those of ordinary skill in the art without departing from the scope and spirit of the described embodiments.
