Abstract
Description
Technical Field
[0001] The utility model relates to a sealing device, in particular to a sealing device used for sealing between a grille dirt remover and a water channel. Background Art
[0002] In the production and operation of sewage treatment plants, in order to protect the environment and prevent air pollution, it is necessary to seal all process links where odor is generated, and extract the odor under negative pressure and deodorize it before discharging it into the atmosphere. Among them, the process links that need to be deodorized include the screen deodorizer and the water channel where it is located.
[0003] Because the screen cleaner needs to pick up garbage from the sewage in the canal, its slag bucket or rake teeth need to reciprocate in the canal and above the ground. Therefore, the sealing of the screen cleaner and the canal needs to take into account that the moving parts are not restricted by the sealing device. At present, most sewage treatment plants seal the screen cleaner by covering the equipment and the canal as a whole. Although this sealing method solves the problem of odor sealing, it also brings the following problems: the sealed space is too large, which brings a greater workload to the negative pressure extraction of the deodorizing device; after the screen cleaner is sealed, it is equivalent to creating a limited space environment, which brings safety hazards and work inconvenience to equipment maintenance and overhaul; the construction workload is large and the cost is high. Utility Model Content
[0004] In order to solve the above-mentioned problems, the present application provides a sealing device for sealing between a screen cleaner and a water channel, which directly seals the water channel and the screen cleaner at the top of the water channel. The smaller sealing space not only solves the water channel sealing problem, but also does not affect the operation of the moving parts of the screen cleaner, and has wide promotion and use value.
[0005] The purpose of the utility model is achieved through the following technical solution: a sealing device for sealing between a grille dirt remover and a water channel, comprising:
[0006] Rotating mechanism;
[0007] A sealing plate, mounted on the rotating mechanism, which can be turned over with the rotating mechanism as a fulcrum to be in an open state or a sealed state;
[0008] The traction mechanism is connected to the sealing plate and is used for traction of the sealing plate from an open state to a sealed state.
[0009] The present application arranges the sealing plate to be flippable so that the sealing plate can cover the water channel opening near the screen dirt remover without affecting the normal movement of the slag bucket on the screen dirt remover.
[0010] Wherein, a bend is formed on the sealing plate so that the sealing plate is divided into a first sealing section and a second sealing section from the bend; when the sealing plate is in a sealed state, the first sealing section is perpendicular to the track of the grille cleaner, and the second sealing section covers the opening of the canal.
[0011] The bent sealing plate can better match the distribution direction of the grille dirt remover and the water channel, thereby improving the sealing performance.
[0012] The first sealing section of the sealing plate is provided with a notch for avoiding the track of the grille dirt remover. In addition, the first sealing section of the sealing plate is provided with a steel rope groove for avoiding the steel wire rope of the grille dirt remover. Thus, the sealing plate can better cooperate with the grille dirt remover.
[0013] The entrance of the steel rope groove is provided with a chamfer, and the setting of the chamfer enables the steel wire rope on the grille dirt remover to be better inserted into the steel rope groove when the sealing plate is turned over.
[0014] The sealing plate is provided with a counterweight block, and the provision of the counterweight block can make the sealing plate be in a sealing state more stably.
[0015] Preferably, the rotating mechanism comprises:
[0016] Two supports;
[0017] The rotating shaft is rotatably arranged between the two supports; the sealing plate is fixed on the rotating shaft.
[0018] The traction mechanism comprises:
[0019] The traction rope of the automatic telescopic take-up device is connected with the second sealing section of the sealing plate.
[0020] The sealing plate is pulled by the automatic wire-retracting function of the automatic retractable wire-retractor, so that the sealing plate is restored from the open state to the sealed state.
[0021] Preferably, the traction mechanism further comprises:
[0022] The pulley block is composed of two pulleys arranged upper and lower; the traction rope of the automatic telescopic take-up device passes between the upper and lower pulleys.
[0023] The present application can ensure that the traction rope of the automatic retractable wire take-up device can be easily retracted and retracted by setting a pulley block.
[0024] Sealing strips are arranged around the sealing plate to improve the sealing performance between the sealing plate and surrounding components.
[0025] Compared with the prior art, the present application has the following beneficial effects: the utility model can seal the water channel and the screen dirt remover directly at the top of the water channel, and the smaller sealing space solves the water channel sealing problem while not affecting the operation of the moving parts of the screen dirt remover, and has wide promotion and use value.

DETAILED DESCRIPTION
[0034] In order to enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments.
[0035] Example
[0036] In the actual production process, the opening of the water channel 8 in the factory area will be covered with the water channel sealing plate 7 to prevent the odor in the water channel 8 from overflowing. Due to the need to cooperate with the slag bucket 62 of the grid dirt remover 6 to move up and down, the opening of the water channel 8 near the grid dirt remover 6 cannot be sealed using the traditional water channel sealing plate 7. This embodiment discloses a sealing device for sealing between the grid dirt remover and the water channel, which can seal the opening of the water channel 8 near the grid dirt remover 6 without affecting the normal operation of the slag bucket 62 of the grid dirt remover 6.
[0037] like Figure 1 , 2 As shown, the sealing device for sealing between the screen dirt remover and the water channel of this embodiment includes three parts: a rotating mechanism 2, a sealing plate 1 and a traction mechanism.
[0038] The rotating mechanism 2 includes two supports 21 and a rotating shaft 23. The two supports 21 are respectively installed on both sides of the water channel 8; the rotating shaft 23 can be made of a stainless steel pipe, and its two ends are rotatably installed between the two supports 21 through a stamped bearing seat and a bearing 22.
[0039] Bolt connection holes are provided on the rotating shaft 23 and the sealing plate 1. The sealing plate 1 is fixedly connected to the rotating shaft 23 by bolts. When the rotating shaft 23 rotates, the sealing plate 1 can be flipped up and down with the rotating shaft 23 as a fulcrum, so that the sealing plate 1 can switch between an open state and a sealed state.
[0040] In addition, a pulling mechanism is connected to the sealing plate 1 , and is used to pull the sealing plate 1 from the open state to the sealed state.
[0041] The sealing plate 1 of the present embodiment is reversible so that it can seal the opening of the water channel without affecting the normal operation of the slag bucket 62 of the grid dirt remover 6.
[0042] The sealing plate 1 in the present embodiment is made of a stainless steel plate with a thickness of about 2 mm, and a bend is formed thereon. It can be understood that the sealing plate 1 in the present embodiment is divided into a first sealing section and a second sealing section from the bend, and an appropriate angle is formed between the first sealing section and the second sealing section, so that the sealing plate 1 is configured so that when in a sealed state, the first sealing section is perpendicular to the track of the grille cleaner 6 to better dock the grille cleaner 6, and the second sealing section forms an angle matching the canal sealing plate 7 on the canal 8, so that the second sealing section can be connected to the canal sealing plate 7 to continue to seal the opening of the canal 8 near the grille cleaner 6, such as Figure 3 shown.
[0043] In order to facilitate the rotation of the sealing plate 1, the width of the sealing plate 1 can be slightly smaller than the width of the water channel 8 to ensure that the sealing plate 1 will not scratch the wall of the water channel 8 when it is turned over. In addition, the sealing strips can be fixed around the sealing plate 1 with self-tapping screws. The sealing strips are preferably made of soft rubber materials and are used to cover the gaps between the sealing plate 1 and the grille dirt remover 6, the water channel, and the water channel sealing plate 7 on the water channel.
[0044] In this embodiment, the first sealing section of the sealing plate 1 is provided with a notch 11 for avoiding the track of the grille dirt remover 6 and a steel rope groove 12 for avoiding the steel wire rope 61 of the grille dirt remover 6. The positions of the notch 11 and the steel rope groove 12 correspond to the positions of the track of the grille dirt remover 6 and the steel wire rope 61.
[0045] The entrance of the steel rope groove 12 may be provided with a chamfer 13 , and the setting of the chamfer 13 enables the steel wire rope 61 on the grille dirt remover to be better inserted into the steel rope groove 12 when the sealing plate 1 is turned over.
[0046] In another implementation of this embodiment, a counterweight 3 may be provided on the sealing plate 1, and the number and weight of the counterweight 3 are only required to ensure that the parts of the sealing plate 1 located on both sides of the rotating shaft remain balanced when in the sealed state.
[0047] Specifically, the traction mechanism includes an automatic telescopic take-up device 5 and a pulley block 4, and the pulley block 4 is composed of two pulleys arranged upper and lower; the automatic telescopic take-up device 5 is installed on the canal sealing plate 7, and the pulley block 4 is fixed by a bracket. The traction rope 51 of the automatic telescopic take-up device 5 passes between the upper and lower pulleys and is connected to the second sealing section of the sealing plate 1.
[0048] like Figure 4 As shown, when the slag bucket 62 of the grille dirt remover 6 moves upward, the slag bucket 62 pushes open the sealing plate 1, causing the sealing plate 1 to rotate clockwise around the rotating shaft, and the sealing plate 1 is in an open state; when the slag bucket 62 is separated from the sealing plate 1, the sealing plate 1 is restored to a sealed state under the action of the automatic telescopic take-up device 5 and its traction rope 51. Figure 5 As shown, when the slag bucket 62 moves downward, the slag bucket 62 pushes away the sealing plate 1, causing the sealing plate 1 to rotate counterclockwise around the rotating shaft, and the sealing plate 1 is in an open state; when the slag bucket 62 is separated from the sealing plate 1, the sealing plate 1 is restored to a sealed state under the action of the automatic telescopic take-up device 5 and its traction rope 51.
[0049] It should be noted that the sealing plate 1 of the present embodiment is in a canal sealing state most of the time, and is opened only for a very short time when the slag bucket 62 passes through the sealing plate 1 (about 10 seconds each time, and the cumulative opening time is about 8 minutes per day); on the other hand, since there is always negative pressure suction in the canal, even if the sealing plate 1 is opened, it is usually difficult for the odor to escape. Therefore, the present embodiment can achieve the expected sealing effect.
[0050] The present embodiment has a simple structure and good airtightness. It does not affect the operation of the equipment and can also be opened and closed automatically without consuming electricity. It has good promotion and use value for the sealing of coarse screen dirt removers in sewage treatment plants, such as slag bucket type or rake tooth type coarse screen dirt removers. Of course, the sealing device of the present embodiment is also applicable to another common rotary coarse screen dirt remover; because the rotary coarse screen of the rotary coarse screen dirt remover does not have a steel wire rope, and the rake teeth used for slag scooping are much smaller than the slag bucket, so there is no need to set a corresponding steel rope groove on the sealing plate of the corresponding sealing device, and the contour structure of the sealing plate is simpler, which will not be repeated here.
[0051] It should be noted that all features disclosed in this specification, or steps in all methods or processes disclosed, except for mutually exclusive features and / or steps, can be combined in any manner.
[0052] In addition, the above specific embodiments are exemplary, and those skilled in the art can come up with various solutions inspired by the disclosure of the utility model, and these solutions also belong to the disclosure scope of the utility model and fall within the protection scope of the utility model. Those skilled in the art should understand that the utility model specification and its drawings are illustrative and do not constitute a limitation of the claims. The protection scope of the utility model is defined by the claims and their equivalents.
