Detailed Implementation

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] The purpose of this invention is to provide a correction switch for belt filter equipment to solve the problems existing in the prior art, reduce the corrosion of components, and ensure the long-term stable operation of components.

[0021] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0022] Example 1 This embodiment provides a correction switch for a belt filter device, such as... Figures 1-4 As shown, the system includes a transmission assembly 2, a guide assembly 3, and at least one sensing assembly 4. The transmission assembly 2 has a first contact rod 22, a second contact rod, and at least one output end. The first contact rod 22 and the second contact rod are respectively disposed on both sides of the filter cloth belt 12 and are used to contact the corresponding side of the filter cloth belt 12. The output end is disposed on the side of the filter cloth belt 12 and can be separated from the space above the filter cloth belt 12. Under the constraint of the guide assembly 3, the output end can reciprocate in the width direction of the filter cloth belt 12, and in the width direction of the filter cloth belt 12, the output end, the first contact rod 22, and the second contact rod can move synchronously. The sensing assembly 4 corresponds one-to-one with the output end and is used to communicate with the protective correction assembly (the protective correction assembly corrects the already misaligned filter cloth belt 12). The sensing assembly 4 can send a signal indicating that the filter cloth belt 12 is misaligned.

[0023] By configuring a transmission assembly 2, a guide assembly 3, and a sensing assembly 4, the first contact rod 22 and the second contact rod of the transmission assembly 2 are respectively positioned on both sides of the filter cloth belt 12 and in contact with the filter cloth belt 12, undertaking the force transmission function when the filter cloth belt 12 is misaligned. The output end of the transmission assembly 2 is located on the side of the filter cloth belt 12 and separated from the space above the filter cloth belt 12, avoiding direct exposure to the area around the filter cloth belt 12 where moisture concentration and corrosive substance concentration are high. At the same time, under the constraint of the guide assembly 3, the output end can move synchronously back and forth with the first contact rod 22 and the second contact rod in the width direction of the filter cloth belt 12, ensuring that the displacement of the filter cloth belt 12 when misaligned can be controlled. The signal is accurately transmitted to the output end, and the sensing component 4 corresponds one-to-one with the output end and is communicatively connected to the protective correction component. The movement of the output end can generate a deviation signal of the filter cloth belt 12. This design uses the first contact rod 22 and the second contact rod as force transmission components that directly contact the filter cloth belt 12, so that the core sensing component 4 is separated from the corrosive environment above the filter cloth belt 12 through the output end, avoiding direct corrosion of the sensing component 4 by water vapor and corrosive substances. Ultimately, this achieves the technical effect of preventing corrosion and rust of the sensing component 4, ensuring its reliable operation, and extending its service life. At the same time, it ensures that the deviation signal of the filter cloth belt 12 can be accurately transmitted to the protective correction component, ensuring the normal implementation of the correction action.

[0024] Specifically, when the filter cloth belt 12 deviates from its designated path, it drives the transmission assembly 2 to move. Then, the sensing assembly 4, which is connected to the transmission assembly 2, senses the signal of the filter cloth belt 12 deviating from its designated path and sends the signal to the protective correction assembly (this part of the structure is the existing equipment structure and will not be described in detail here). The protective correction assembly corrects the filter cloth belt 12. Because the filter cloth belt 12 treats domestic sewage, water vapor is generated during the process, which can easily corrode the sensing assembly 4. By setting the transmission assembly 2, the sensing assembly 4 is separated from the filter cloth belt 12, so that the two do not come into direct contact, reducing the corrosion of the sensing assembly 4 (i.e., the component) and extending the service life of the sensing assembly 4. The transmission assembly 2 has a simple structure, is less affected by water vapor, and can operate for a longer period of time.

[0025] The following is an explanation of belt filter equipment: Reference Figure 1A belt filter device includes a frame 1, a filter cloth belt 12, and multiple idlers 11. Both ends of the idlers 11 are rotatably connected to the frame 1. The idlers 11 are arranged along the width of the frame 1, and the filter cloth belt 12 is arranged along the length of the frame 1. The idlers 11 support the filter cloth belt 12. The rotation of the idlers 11 can drive the filter cloth belt 12 to move. However, the filter cloth belt 12 may deviate during the movement. Therefore, the device is also equipped with a protective correction component (this component is an existing component and will not be described in detail here). This component can pull the deviated filter cloth belt 12 back in the opposite direction, so that the filter cloth belt 12 returns to the middle position of the idlers 11, thereby improving the wastewater filtration effect.

[0026] The following are the relevant settings for transmission component 2: Among the optional solutions in this embodiment, the more preferred one is as follows: Figure 1 , Figure 2 and Figure 4 As shown, a first rolling sleeve 23 is rotatably disposed on the first contact rod 22 about the axis of the first contact rod 22; a second rolling sleeve is rotatably disposed on the second contact rod about the axis of the second contact rod; the outer side walls of the first rolling sleeve 23 and the second rolling sleeve are used to contact the corresponding side walls of the filter cloth belt 12.

[0027] Among the optional solutions in this embodiment, the more preferred one is as follows: Figure 1 , Figure 2 and Figure 4 As shown, the transmission assembly 2 includes a crossbar 21; the crossbar 21 is positioned across the top of the filter cloth belt 12; the upper ends of the first contact rod 22 and the second contact rod are both fixedly connected to the crossbar 21; the guide assembly 3 includes two oppositely arranged guide blocks 31, which are respectively fixedly arranged on both sides of the filter cloth belt 12; the guide blocks 31 have through guide holes in the width direction of the filter cloth belt 12; the two ends of the crossbar 21 are respectively slidably arranged in the corresponding guide holes, and the part of the crossbar 21 that protrudes from the guide hole can form an output end.

[0028] Specifically, the guide hole is used to restrict the crossbar 21 to reciprocate only along the width direction of the filter cloth belt 12, thereby driving the sensing block 41 (when the sensing component 4 is as follows). Figure 1 and Figure 4 When the setting mode is used, the position is moved to transmit a signal that the filter cloth belt 12 is off-center.

[0029] Specifically, both the first contact rod 22 and the second contact rod are perpendicular to the crossbar 21. When the filter cloth belt 12 deviates, the side of the filter cloth belt 12 that deviates will first push the corresponding first contact rod 22 or second contact rod (the actual contact push is the first rolling sleeve 23 on the first contact rod 22 or the second rolling sleeve on the second contact rod), and then drive the crossbar 21 to move.

[0030] Specifically, when the filter cloth belt 12 deviates and pushes the corresponding first rolling sleeve 23 or second rolling sleeve to move, the first rolling sleeve 23 or second rolling sleeve rotates, converting the static friction between it and the filter cloth belt 12 into rolling friction, reducing the friction between the first rolling sleeve 23 or second rolling sleeve and the filter cloth belt 12, thereby reducing the wear of the filter cloth belt 12.

[0031] Among the optional solutions in this embodiment, the more preferred one is as follows: Figure 1 , Figure 2 and Figure 4 As shown, a first short rod 24 is fixedly mounted on the first contact rod 22. The axis of the first short rod 24 is parallel to the axis of the cross rod 21, and there is a gap between the outer wall of the first short rod 24 and the outer wall of the cross rod 21. A second short rod is fixedly mounted on the second contact rod. The axis of the second short rod is parallel to the axis of the cross rod 21, and there is a gap between the outer wall of the second short rod and the outer wall of the cross rod 21. The first short rod 24 and the second short rod are slidably mounted in the corresponding guide holes of the corresponding parts of the cross rod 21.

[0032] Specifically, a first short rod 24 and a second short rod are set parallel to the crossbar 21, and the crossbar 21, the first short rod 24 and the second short rod are all placed in the corresponding guide holes. When the filter cloth belt 12 pushes the first rolling sleeve 23 or the second rolling sleeve, a force is generated that causes the crossbar 21 to rotate. By setting the first short rod 24 and the second short rod, the probability of the crossbar 21 rotating is reduced, and the correction efficiency of the filter cloth belt 12 is improved.

[0033] Among the optional solutions in this embodiment, the more preferred one is as follows: Figure 1 , Figure 3 and Figure 4 As shown, it also includes a crossbeam 15; the crossbeam 15 is used to span across and be fixedly installed above the filter cloth belt 12; in the vertical direction, the crossbeam 15 is located above the crossbar 21; and the crossbeam 15 is connected to the crossbar 21 by at least one suspension rope 6 (the upper end of the suspension rope 6 is fixedly connected to the crossbeam 15, and the lower end of the suspension rope 6 is fixedly connected to the crossbar 21).

[0034] Specifically, a vertical rod 14 is fixed at each end of the crossbeam 15, and the lower end of each vertical rod 14 is fixedly connected to the equipment frame 1.

[0035] Specifically, several suspension ropes 6 are installed on the crossbar 21 to generate an upward pulling force on the crossbar 21, reduce the friction between the crossbar 21 and the guide hole, and make the crossbar 21 slide more smoothly when sliding left and right.

[0036] Among the optional solutions in this embodiment, the more preferred one is as follows: Figure 1 , Figure 2and Figure 4 As shown, a lifting ring 211 for fixing the lifting rope 6 is fixedly installed on the crossbar 21; the lifting ring 211 corresponds to the lifting rope 6 one by one.

[0037] Specifically, a lifting ring 211 is installed on the crossbar 21 to facilitate the installation and replacement of the lifting rope 6.

[0038] In the optional solutions of this embodiment, the preferred option is that the suspension rope 6 is a corrosion-resistant soft nylon rope. Because the equipment treats domestic sewage, where there is a high humidity level in the treatment room, using a corrosion-resistant soft nylon rope for the suspension rope 6 allows for longer use in humid environments, reducing the frequency of rope replacement.

[0039] In the optional embodiments of this example, a preferred arrangement is that the first rolling sleeve 23 is rotatably mounted on the first contact rod 22 via a first bearing; and the second rolling sleeve is rotatably mounted on the second contact rod via a second bearing. The bearings enable relative rotation while also reducing friction between the two components.

[0040] The following are the settings instructions for guide component 3: Specifically, the guide block 31 is fixed to the equipment frame 1 by the limiting rod 32 (that is, the lower end of the limiting rod 32 is fixedly connected to the equipment frame 1, and the upper end of the limiting rod 32 is fixedly connected to the guide block 31).

[0041] The following are the settings instructions for sensor component 4: Specifically, when there is only one output terminal, there is also only one sensing component 4. The specific configuration methods are as follows: Among the optional solutions in this embodiment, the more preferred one is as follows: Figure 1 and Figure 4 As shown, the number of output terminals is one; the sensing component 4 includes a sensing block 41 and two proximity switches 42 (e.g., ...). Figure 1 and Figure 4 (Settings in the middle); the sensing block 41 is fixedly set on the output end; the positions of the two proximity switches 42 are fixed; the sensing block 41 is located between the two proximity switches 42, and the sensing block 41 and one of the proximity switches 42 correspond to trigger the left offset signal of the filter cloth belt 12, and the sensing block 41 and the other proximity switch 42 correspond to trigger the right offset signal of the filter cloth belt 12; each proximity switch 42 is used to communicate with the protective correction component; Alternatively, the sensing component 4 includes two sensing blocks 41 and two proximity switches 42; both sensing blocks 41 are fixedly mounted on the output end; the positions of the two proximity switches 42 are fixed, and there is a one-to-one correspondence between the sensing blocks 41 and the proximity switches 42 (in two forms: both sensing blocks 41 are located between the two proximity switches 42, or the two proximity switches 42 are located between the two sensing blocks 41); one proximity switch 42 corresponds to one sensing block 41 to trigger a left offset signal of the filter cloth belt 12, and the other proximity switch 42 corresponds to the other sensing block 41 to trigger a right offset signal of the filter cloth belt 12; each proximity switch 42 is used for communication connection with the protective correction component; Alternatively, the sensing component 4 includes two sensing blocks 41 and a proximity switch 42; the proximity switch 42 is fixedly mounted on the output end; the two sensing blocks 41 are fixed in position, and the proximity switch 42 is located between the two sensing blocks 41. The proximity switch 42 triggers a left offset signal of the filter cloth belt 12 corresponding to one of the sensing blocks 41, and the proximity switch 42 triggers a right offset signal of the filter cloth belt 12 corresponding to the other sensing block 41; the proximity switch 42 is used for communication connection with the protective correction component. Alternatively, the sensing component 4 includes two sensing blocks 41 and two proximity switches 42; both proximity switches 42 are fixedly mounted on the output end; the positions of the two sensing blocks 41 are fixed, and the proximity switches 42 correspond one-to-one with the sensing blocks 41 (the method is the same as described above for corresponding positions, and will not be repeated here); one proximity switch 42 corresponds to one sensing block 41 to trigger the left offset signal of the filter cloth belt 12, and the other proximity switch 42 corresponds to the other sensing block 41 to trigger the right offset signal of the filter cloth belt 12; each proximity switch 42 is used to communicate with the protective correction component.

[0042] Specifically, when there are two output terminals, there are also two sensing components 4. In this case, the two output terminals are located on both sides of the filter cloth belt 12, and the sensing components 4 correspond one-to-one with the output terminals. In this case, the sensing component 4 only needs to include one sensing block 41 and one proximity switch 42. The sensing block 41 is fixed on the output terminal, and the proximity switch 42 is fixed in position. Alternatively, the sensing block 41 is fixed in position, and the proximity switch 42 is fixed on the output terminal. The sensing block 41 and proximity switch 42 of the sensing component 4 located on the left side of the filter cloth belt 12 are used to trigger the left offset signal of the filter cloth belt 12. The sensing block 41 and proximity switch 42 of the sensing component 4 located on the right side of the filter cloth belt 12 are used to trigger the right offset signal of the filter cloth belt 12.

[0043] Regarding other related settings: Among the optional solutions in this embodiment, the more preferred one is as follows: Figure 1As shown, it also includes a vertical partition 5; the vertical partition 5 is used to fix it between the output end and the filter cloth belt 12; the sensing component 4 includes a sensing block 41 and two proximity switches 42; the vertical partition 5 has a through hole, and one end of the crossbar 21 passes through the guide hole and the through hole in sequence and is fixedly connected to the sensing block 41; a side plate 13 is fixedly installed on the vertical partition 5, and the two proximity switches 42 are fixedly installed on the side plate 13.

[0044] Specifically, the vertical baffle 5 can block the water vapor generated when the filter cloth belt 12 is running, reduce the corrosion of the sensing component 4 by the water vapor, extend the service life of the sensing component 4, improve the stability of the sensing component 4 during operation, and thus improve the correction effect of the filter cloth belt 12.

[0045] Specifically, the implementation principle of this embodiment is explained as follows: During the operation of the belt filter equipment, the filter cloth belt 12 may deviate from its normal position. When the filter cloth belt 12 deviates to the right, it pushes the second rolling sleeve located on the right side. While being pushed to the right, the second rolling sleeve rotates itself, reducing the friction between itself and the filter cloth belt 12, thereby reducing the wear of the filter cloth belt 12. While being pushed to the right, the second rolling sleeve also drives the crossbar 21 to move to the right. The crossbar 21 drives the sensing block 41 to move to the right. The proximity switches 42 located on the left and right sides of the sensing block 41 receive the signal of the sensing block 41 moving to the right and send a signal to the protective correction component that the filter cloth belt 12 has deviated to the right. The protective correction component performs corresponding actions to correct the deviated filter cloth belt 12, so that the filter cloth belt 12 returns to the normal position. The same principle applies when the filter cloth belt 12 deviates to the left.

[0046] This utility model uses specific examples to illustrate its principles and implementation methods. The above description of the embodiments is only for the purpose of helping to understand the method and core idea of ​​this utility model. At the same time, for those skilled in the art, there will be changes in the specific implementation methods and application scope based on the idea of ​​this utility model. In summary, the content of this specification should not be construed as a limitation of this utility model.
