Description

Technical Field

[0001] The invention belongs to the technical field of sewage treatment, and in particular relates to a pool opening sealing device and a sewage pool using the same. Background Art

[0002] Sewage treatment plant tanks are generally classified as either open, uncovered (the entire tank is exposed) or partially open (partially covered, with the unobstructed portion used for the movement of sewage treatment equipment). With increasingly stringent environmental protection requirements and rapid urbanization, residents are demanding higher standards for air quality in their surroundings. Sewage treatment tanks often release volatile odors, seriously polluting the air. To prevent these odors from escaping, the tank openings must be sealed.

[0003] For open uncovered sewage pools, the existing technology generally builds a sealed room outside the sewage treatment pool to prevent the escape of odor. This treatment method takes up space and is costly. For partially open sewage pools, the existing technology generally adopts the following two sealing methods:

[0004] 1) Use a cover cloth to cover the open part of the sewage pool, one end of the cover cloth is connected to the end of the sewage pool, and the other end is connected to the slag cleaning equipment;

[0005] 2) Further seal the open part of the sewage pool so that only a gap for the slag cleaning equipment to move forward is retained in the sewage pool.

[0006] The first sealing method often causes the cover cloth to get stuck or fail to completely cover the pool opening as the slag cleaning equipment moves, resulting in an unsatisfactory sealing effect. The second sealing method still has a gap for the slag cleaning equipment to move, and the gap cannot be completely sealed, so that the odor in the sewage pool can still escape through the gap, and the sealing effect is also unsatisfactory.

[0007] In view of the problems existing in the existing partially open sewage pool mouth sealing device, technicians in this field hope to propose a pool mouth sealing device with good sealing effect. Summary of the Invention

[0008] In order to solve all or part of the above problems, the present invention aims to provide a pool opening sealing device to effectively seal the pool opening.

[0009] According to a first aspect of the present invention, a pool mouth sealing device is proposed, comprising a plurality of support plates arranged in parallel in sequence for sliding connection with the edge of the pool mouth, and a sealing cloth with a sealing cover provided on the outer edge of each support plate. The pool mouth sealing device is constructed to have an initial position and an open position, and can reciprocate between the initial position and the open position, wherein, in the initial position, the sealing cloth between any adjacent support plates is folded and clamped between the adjacent support plates; in the open position, a spacing is formed between any adjacent support plates, and the sealing cloth between any adjacent support plates is stretched between the adjacent support plates.

[0010] Furthermore, the support plate includes a horizontal section and vertical sections connected to both ends of the horizontal section, and the sealing cloth and sealing cover are arranged on the top wall of the horizontal section and the outer side wall of the vertical section.

[0011] Furthermore, the pool mouth sealing device also includes a track fixed on the edge of the pool mouth, a first sliding component arranged at the bottom of the horizontal section near the vertical section and / or a second sliding component arranged at the bottom of the vertical section near the horizontal section, the first sliding component is slidably connected to the top wall of the track, and the second sliding component is slidably connected to the side wall of the track.

[0012] Furthermore, the first sliding component includes a first fixed plate for fixedly connecting to the horizontal section and a first roller formed on one end of the first fixed plate close to the track; the second sliding component includes a second fixed plate for fixedly connecting to the vertical section and a second roller formed on one end of the second fixed plate close to the track.

[0013] Furthermore, the second sliding component includes a fixing piece for fixing the second fixing plate on the vertical section, and a fixing hole for passing the fixing piece is formed on the second fixing plate; and a slot for engaging with the horizontal section is formed on the first fixing plate.

[0014] Furthermore, the first fixing plate and / or the second fixing plate are made of stainless steel or resin, and the first roller and / or the second roller are made of stainless steel or resin.

[0015] Furthermore, the horizontal section of the support plate further includes a transition section formed at the connection between the horizontal section and the vertical section, and the first sliding component is provided on an end of the transition section opposite to the track.

[0016] Furthermore, the pool opening sealing device further comprises a sealing plate located at either end of the pool opening sealing device, and the shape of the sealing plate is configured to have a shape capable of completely closing the pool opening.

[0017] Furthermore, a limiting belt is provided on the sealing cloth between adjacent support plates in a direction perpendicular to the adjacent support plates. When the pool mouth sealing device is in the open position, the length of the limiting belt is less than or equal to the spacing between adjacent support plates.

[0018] According to another first aspect of the present invention, a sewage pool is proposed, comprising at least two of the above-mentioned pool mouth sealing devices, wherein one end of each pool mouth sealing device having a sealing plate is used to be sealed and connected to the two ends of the pool mouth respectively, and the other end of each pool mouth sealing device is simultaneously sealed and connected to a slag cleaning device for cleaning slag from the sewage pool, so that when the slag cleaning device moves in the sewage pool, one of the two pool mouth sealing devices moves toward an open position and the other moves toward an initial position.

[0019] Compared with the prior art, the pool mouth sealing device of the present invention has a simple structure and can achieve complete closure of the pool mouth when the slag cleaning equipment is running in the pool. At the same time, when the pool mouth sealing device is pulled by the slag cleaning equipment, the pool mouth sealing device can keep pace with the movement of the slag cleaning equipment without any jamming.

[0025] In order to better understand the purpose, structure and function of the present invention, a pool opening sealing device of the present invention is further described in detail below with reference to the accompanying drawings.

[0026] Figure 1-3 FIG. 1 shows the structure of the pool opening sealing device 100 according to an embodiment of the present invention. Figure 1-3As shown, the pool mouth sealing device 100 includes a plurality of support plates 1 arranged in sequence and used for sliding connection with the edge of the pool mouth, and a sealing cloth 2 with a sealing cover arranged on the outer edge of each support plate 1. The pool mouth sealing device 100 is constructed to have an initial position and an open position, and can move back and forth between the initial position and the open position, wherein, in the initial position, the sealing cloth between any adjacent support plates 1 is folded and clamped between the adjacent support plates 1; in the open position, a spacing is formed between any adjacent support plates 1, and the sealing cloth between any adjacent support plates 1 is stretched between the adjacent support plates 1.

[0027] It should be noted that the pool opening sealing device 100 of the present invention can be used to seal various pool openings, and a semi-open sewage treatment pool is used as an example for explanation.

[0028] When the slag cleaning device 7 such as a bridge-type sand suction machine is running back and forth in the sewage treatment pool, two pool mouth sealing devices 100 of this embodiment can be set, one end of the two pool mouth sealing devices 100 is respectively sealed and connected to the front and rear ends of the slag cleaning device 7 in the direction of travel, and the other end of the two pool mouth sealing devices 100 is respectively sealed and connected to the two ends of the pool mouth in the length direction. Figure 4 As shown, the operation of the slag cleaning equipment 7 from the left end to the right end of the pool mouth is taken as an example: when the slag cleaning equipment 7 is located at the left end of the pool mouth, a pool mouth sealing device 100 connected to the left end of the pool mouth and simultaneously connected to the left end of the slag cleaning equipment 7 is in a compressed initial position A; another pool mouth sealing device 100 connected to the right end of the pool mouth and simultaneously connected to the right end of the slag cleaning equipment 7 is in a stretched open position B. At this time, the pool mouth of the sewage treatment pool located at the left end of the slag cleaning equipment 7 is covered by one pool mouth sealing device 100, the pool mouth of the sewage treatment pool located at the right end of the slag cleaning equipment 7 is covered by another pool mouth sealing device 100, and the pool mouth located at the lower end of the slag cleaning equipment 7 is covered by the slag cleaning equipment 7. That is, at this time, the pool mouth of the sewage treatment pool is jointly covered and sealed by the slag cleaning equipment 7 and the two pool mouth sealing devices 100; when the slag cleaning equipment 7 moves from the left end of the pool mouth to the right end of the pool mouth (that is, Figure 4When the slag cleaning equipment 7 moves in the direction indicated by the middle arrow), any adjacent support plates 1 of a pool mouth sealing device 100 arranged at the left end of the slag cleaning equipment 7 are pulled by the slag cleaning equipment 7 to gradually move away from each other until the maximum distance between any adjacent support plates 1 is reached, and the pool mouth sealing device 100 is in the open position B. At the same time, any adjacent support plates 1 of another pool mouth sealing device 100 arranged at the right end of the slag cleaning equipment 7 are pushed by the slag cleaning equipment 7 to gradually move closer to each other until any adjacent support plates 1 fold the sealing cloth therein and abut against the two, and the pool mouth sealing device 100 is in the initial position A. During the reciprocating movement of the slag cleaning equipment 7 in the pool mouth, the pool mouth of the sewage treatment pool is always covered and sealed by the slag cleaning equipment 7 and the two pool mouth sealing devices 100, which effectively ensures a good sealing effect on the pool mouth of the sewage pool. It should be noted that the "initial position A" mentioned here refers to the position of any two adjacent support plates 1 of the pool opening sealing device 100 when they are in a compressed state, and the "open position B" refers to the position of any two adjacent support plates 1 of the pool opening sealing device 100 when they are in a compressed state. Figure 4 The figure illustrates the movement of the slag cleaning equipment 7 from the left end to the right end of the pool mouth. Therefore, the "initial position A" and "open position B" shown in the figure are limited to indicating the position state of the pool mouth sealing device 100 when the slag cleaning equipment 7 moves from the left end to the right end of the pool mouth.

[0029] The pool mouth sealing device 100 of the embodiment of the present invention is provided with a plurality of support plates 1 that are slidably connected to the edge of the pool mouth and a sealing cloth 2 whose sealing cover is provided on the outer edge of each support plate 1, and the pool mouth sealing device 100 can reciprocate between the initial position A and the open position B, so that when the slag cleaning equipment 7 or other treatment equipment drives the pool mouth sealing device 100 to reciprocate in the sewage treatment pool, it can always maintain a seal with the pool mouth. It has a simple structure and is easy to operate, which greatly improves the good sealing effect of the sewage pool mouth.

[0030] According to the pool mouth sealing device 100 of this embodiment, the support plate 1 may include a horizontal section 11 and a vertical section 12 connected to both ends of the horizontal section 11, and the sealing cloth 2 can be simultaneously sealed and covered on the top wall of the horizontal section 11 and the outer wall of the vertical section 12. By arranging the horizontal section 11 and the vertical section 12, the support plate 1 can also be erected on the pool mouth with a protruding edge, so that the support plate 1 can be limited on the pool mouth with a protruding edge. At the same time, this arrangement also helps to improve the sealing effect between the support plate 1 and the pool mouth. It is worth noting that the specific shape of the support plate 1 can be specifically designed according to the structure of different sewage treatment tanks, as long as its structure can achieve good coordination with the pool mouth and a good sealing effect.

[0031] Combine Figure 1-3The pool mouth sealing device 100 may also include a track 3 fixed on the edge of the pool mouth (the structure of the track can be understood to be similar to the structure of the protruding edge of the pool mouth mentioned above. If the pool mouth itself has a protruding edge, there is no need to additionally set the track 3), a first sliding component 4 provided at the bottom of the horizontal section 11 near the vertical section 12 and / or a second sliding component 5 provided at the bottom of the vertical section 12 near the horizontal section 11, the first sliding component 1 is slidably connected to the top wall of the track 3, and the second sliding component 5 is slidably connected to the side wall of the track 3. The track 3 can be provided to guide the support plate 1 on the one hand, and to prevent the support plate 1 from falling into the inside of the pool mouth on the other hand; the provision of the first sliding component 4 and / or the second sliding component 5 can make the sliding connection of the support plate 1 relative to the track smoother, and avoid the phenomenon of the support plate 1 being stuck when moving on the track 3.

[0032] like Figure 2 As shown, the first sliding member 4 may include a first fixing plate 41 for fixedly connecting to the horizontal section 11 and a first roller 42 formed at one end of the first fixing plate 41 close to the track 3; Figure 3 As shown, the second sliding component 5 may include a second fixing plate 51 for fixedly connecting to the vertical section 12 and a second roller 52 formed on one end of the second fixing plate 51 near the track 3. By providing the first fixing plate 41 and the second fixing plate 52 fixedly connected to the support plate 1, the support plate 1 is fixedly connected to the first sliding component 4 and the second sliding component 5, respectively, so that when the first roller 42 and the second roller 52 roll on the track 3, the support plate 1 is driven to move synchronously.

[0033] In a preferred embodiment, the second sliding member 5 may include a fixing member (not shown) for fixing the second fixing plate 51 to the vertical section 12. The second fixing plate 51 may be formed with a fixing hole 511 for passing the fixing member. The first fixing plate 41 may be formed with a slot 43 for engaging with the horizontal section 11. The fixing member may be a bolt or a screw. In this embodiment, the second sliding component 5 fixes the second fixing plate 51 to the support plate 1 by passing the fixing piece through the fixing hole 511, and the first sliding component 4 clamps the first fixing plate 41 to the support plate through the clamping groove 43. This arrangement makes the fixing method of the first sliding component 4 and the second sliding component 5 more flexible, and helps to improve the installation efficiency while ensuring the fixing effect. Since the pool mouth sealing device 100 generally does not have directional deviation in the vertical direction when being pulled by the slag cleaning equipment 7, the first sliding component 4 in the vertical direction can ensure that the first sliding component 4 is stably connected to the support plate 1 by setting the clamping groove 43; while the pool mouth sealing device 100 may have left and right deviations in the horizontal direction, the second sliding component 5 in the horizontal direction can ensure that the second sliding component 5 is stably connected to the support plate 1 by setting the fixing piece and the fixing hole 511 in a more secure fixing manner. It is worth noting that the structures of the first sliding component 4 and the second sliding component 5 can also be exactly the same, and the operator can specifically select the structural form of the first sliding component 4 and the second sliding component 5 according to the specific use environment.

[0034] According to the pool inlet sealing device 100 of this embodiment, the first fixing plate 41 and / or the second fixing plate 51 can be made of stainless steel or a resin material, and the first roller 42 and / or the second roller 52 can be made of stainless steel or a resin material. Since both stainless steel and resin materials are corrosion-resistant and wear-resistant, the use of stainless steel or resin materials makes the first fixing plate 41 and / or the second fixing plate 51, the first roller 42 and / or the second roller 52 all have corrosion-resistant and wear-resistant properties, allowing them to be used in the harsh environment of the sewage treatment pool inlet and having a long service life.

[0035] In a preferred embodiment, the horizontal section 11 of the support plate 1 may further include a transition section 13 (e.g., Figure 1 As shown in FIG. 1 , the first sliding member 4 can be disposed on the end of the transition section 13 opposite the track 3. The provision of the transition section 13 can help save material for the horizontal section and also increase the maximum distance of the horizontal section 11 relative to the tank opening to adapt to the operating characteristics of the slag cleaning device in the sewage tank.

[0036] According to the pool mouth sealing device 100 of this embodiment, the pool mouth sealing device 100 may further include a sealing plate 6 (such as Figure 5 As shown, the sealing plate 6 is shaped to completely seal the pool opening. The provision of the sealing plate 6 allows the pool opening sealing device to fully seal both ends of the pool opening, preventing odors within the sewage treatment tank from escaping through the corresponding end of the pool opening sealing device 100 and polluting the environment.

[0037] Preferably, the sealing plate 6 is in the shape of a rectangle that can completely cover the pool opening.

[0038] In another preferred embodiment, the sealing cloth 2 located between adjacent support plates 1 may be provided with a limiting belt (not shown in the figure) in a direction perpendicular to the adjacent support plates 1, and when the pool mouth sealing device is in the open position, the length of the limiting belt is less than or equal to the spacing between adjacent support plates. Preferably, when the pool mouth sealing device is in the open position, the length of the limiting belt is less than the spacing between adjacent support plates. This arrangement enables the sealing cloth 2 on the two support plates 1 to be in a partially folded state, i.e., not completely stretched flat, when the spacing between any two adjacent support plates 1 increases to a point where it can no longer increase. By providing the limiting belt, it is possible to avoid the sealing cloth on the two support plates 1 being pulled when the spacing between any two adjacent support plates 1 reaches the maximum, thereby affecting the service life of the sealing cloth.

[0039] In a preferred embodiment, the sealing cloth 2 and the limiting belt can both be made of corrosion-resistant fiber materials, such as polyvinylidene fluoride, polyvinyl chloride, etc.

[0040] According to the pool opening sealing device 100 of this embodiment, the support plates at both ends of the pool opening sealing device 100 can be made of metal material, and the support plate 1 located between the support plates at both ends of the pool opening sealing device 100 is made of polypropylene material. Preferably, the metal material is stainless steel metal material.

[0041] Because metal has a greater gravitational pull than polyethylene, the support plates at both ends of the pool opening sealing device 100 are constructed of metal, allowing for efficient fixing to both ends of the pool opening, ensuring effective closure. Furthermore, the polyethylene support plate 1 between the two support plates of the pool opening sealing device 100 offers superior wear and corrosion resistance, enabling it to withstand the harsh environment of a sewage treatment pool opening and resulting in a long service life.

[0042] The present invention also proposes a sewage pool 200, such as Figure 5As shown, it includes at least two of the above-mentioned pool mouth sealing devices 100, and one end of each pool mouth sealing device 100 with a sealing plate 6 is used to be sealed and connected to the two ends of the pool mouth respectively, and the other end of each pool mouth sealing device 100 is simultaneously sealed and connected to the slag cleaning equipment 7 for cleaning the sewage pool 200, so that when the slag cleaning equipment 7 moves in the sewage pool, one of the two pool mouth sealing devices 100 moves toward the open position and the other moves toward the initial position.

[0043] It should be noted that in some special cases, such as when two or more treatment devices moving in the same direction are installed in the sewage tank 200 or other tank, the above-mentioned tank opening sealing device 100 is connected between the two or more treatment devices and at both ends of the treatment device and the tank opening to ensure that the tank opening is completely covered and sealed. The operation of each treatment device and the tank opening sealing device 100 is similar to the principles described above and will not be repeated here.

[0044] Compared with the prior art, the pool opening sealing device 100 of the embodiment of the present invention has the following advantages:

[0045] 1) The structure is simple, and the pool opening can be completely covered when the treatment equipment is running in the pool, achieving a good sealing effect.

[0046] 2) When the pool mouth sealing device 100 is pulled by the processing equipment, the pool mouth sealing device 100 can keep consistent with the movement of the processing equipment without getting stuck; at the same time, the wear of the support plate 1 and the sealing cloth 2 is reduced.

[0047] 3) The pool mouth sealing device 100 is applicable to pool mouths of various structures and working environments of various treatment equipments and can be widely used.

[0048] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit them. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some or all of the technical features therein. These modifications or replacements do not deviate the essence of the corresponding technical solutions from the scope of the technical solutions of the embodiments of the present invention, and they should all be included in the scope of the claims and description of the present invention. In particular, as long as there is no structural conflict, the various technical features mentioned in the various embodiments can be combined in any way.
