Description

Technical Field

[0001] This utility model belongs to the field of sewage treatment technology, and in particular to a new type of bar screen for sewage treatment. Background Technology

[0002] A bar screen is a solid-liquid separation device that continuously removes impurities from fluids. It is an indispensable piece of equipment in production processes in industries such as urban sewage treatment, waterworks, power plant intakes, textiles, food processing, papermaking, and leather. It is a widely used solid-liquid screening device in China. Its working principle involves a rake chain rotating against the direction of the water flow, driven by a motor reducer. When the rake chain reaches the upper part of the equipment, the guide wheels and curved rails cause a relative self-cleaning motion between each set of rake teeth, allowing most of the solid material to fall off due to gravity. The remaining material is then swept away by the reverse motion of a sweeper.

[0003] Currently, when wastewater treatment bar screens remove debris from fluids, some debris gets tangled on the rake teeth. To avoid affecting the cleaning effect of the wastewater treatment bar screen, the debris tangled on the rake teeth needs to be cleaned. However, in existing technologies, most of these cleanings are done manually after the bar screen is stopped. This not only increases the workload of the staff but also reduces the cleaning efficiency of the wastewater treatment bar screen, thus affecting its performance. Utility Model Content

[0004] The purpose of this utility model is to provide a new type of bar screen for sewage treatment to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a novel bar screen for sewage treatment, comprising a bar screen body, a cleaning component, a fixing component, and a sliding component; the cleaning component is arranged on the bar screen body; wherein, the cleaning component includes a fixing plate, a fixing rod, a blade holder, and a cleaning blade; two fixing plates are symmetrically fixed to the material discharge end of the bar screen body; the fixing rod is disposed between the two fixing plates, and the fixing rod is connected to the fixing plate through the fixing component; a plurality of blade holders are linearly arrayed and fixed on the circumferential surface of the fixing rod; the cleaning blade is connected to the blade holder through the sliding component; wherein, the cleaning blade contacts the rake teeth of the bar screen body.

[0006] In a preferred embodiment, the blade holder has an inclined structure, with the high end of the blade holder positioned away from the fixing rod and the low end positioned close to the fixing rod.

[0007] In a preferred embodiment, the cleaning blade has a V-shaped surface on the side away from the blade holder.

[0008] In a preferred embodiment, the fixing component includes a guide plate, a guide groove, a threaded groove, and a screw; two guide plates are symmetrically fixed at both ends of the fixing rod; guide grooves are formed on the opposite surfaces of the two fixing plates; wherein the guide plates slide in conjunction with the guide grooves; two threaded grooves are symmetrically formed at both ends of the fixing rod; the screw passes through the fixing plate, and the end of the screw passes through the guide plate and is threadedly connected to the threaded groove.

[0009] In a preferred embodiment, the sliding assembly includes a sliding groove and a sliding block; the blade holder has a sliding groove on the side near the cleaning blade; the sliding block is fixed to the cleaning blade on the side near the blade holder.

[0010] In a preferred embodiment, the sliding block and the sliding groove are in sliding engagement.

[0011] In a preferred embodiment, the sliding block has a T-shaped structure, and the T-shaped surface of the sliding block is positioned away from the direction of the cleaning blade.

[0012] Compared with the prior art, the technical effects and advantages of this utility model are:

[0013] This new type of bar screen for sewage treatment, through its cleaning components, allows for easy operation. First, the bar screen body is fixed in a suitable position. Then, the bar screen body is activated, causing the rake teeth on the body to clean debris from the water. As the rake teeth move, debris entangled on them is squeezed and cut by the cleaning blades, enabling the cleaning blades to effectively remove the debris. This not only reduces the workload for workers but also significantly improves the cleaning efficiency of the bar screen body.

[0014] This new type of bar screen for sewage treatment uses a guide plate, guide groove, threaded groove, and screw. By rotating the screw with a tool, the screw is no longer connected to the threaded groove. Then, the fixed rod is moved, causing the guide plate to slide in the guide groove until the guide plate disengages from the guide groove. This allows the fixed rod to be disassembled, facilitating the replacement of the fixed rod, blade holder, and cleaning blade. This ensures the cleaning blade's efficiency in removing debris entangled on the rake teeth of the bar screen body.

[0015] This new type of bar screen for sewage treatment, by setting up a sliding groove and a sliding block, utilizes the sliding engagement between the sliding block and the sliding groove. The sliding block is set in a T-shape, and the T-shaped surface of the sliding block is set away from the direction of the cleaning blade. This not only allows the cleaning blade to be replaced separately after the fixing rod is removed, greatly reducing the cost of cleaning blade replacement, but also increases the contact area between the sliding block and the sliding groove, improves the friction between the sliding block and the sliding groove, and makes the connection between the sliding block and the sliding groove more stable, thereby ensuring the stability of the cleaning blade installation.

[0029] Unless otherwise defined, the directions of up, down, left, right, front, back, inside and outside involved in this document are based on the directions of up, down, left, right, front, back, inside and outside shown in the figures of the present invention, and are explained here together.

[0030] The connection method can be bonding, welding, bolt connection, etc., which shall be based on actual needs.

[0031] Please see Figures 1 to 5 As shown, this embodiment includes a bar screen body 1, a cleaning component 2, a fixing component 3, and a sliding component 4. The cleaning component 2 is arranged on the bar screen body 1. The cleaning component 2 includes a fixing plate 201, a fixing rod 202, a blade holder 203, and a cleaning blade 204. Two fixing plates 201 are symmetrically fixed at the material discharge end of the bar screen body 1. The fixing rod 202 is located between the two fixing plates 201 and is connected to the fixing plate 201 through the fixing component 3. A plurality of blade holders 203 are linearly arrayed and fixed on the circumferential surface of the fixing rod 202. The cleaning blade 204 is connected to the blade holder 203 through the sliding component 4. The cleaning blade 204 contacts the rake teeth of the bar screen body 1.

[0032] This utility model, through the cleaning component 2, allows the bar screen body 1 to be fixed in a suitable position during use. Then, the bar screen body 1 is started, causing the rake teeth on the bar screen body 1 to clean debris in the water. When the rake teeth of the bar screen body 1 are driven, the debris wrapped around the rake teeth of the bar screen body 1 is squeezed and cut off by the cleaning blade 204, so that the cleaning blade 204 can clean the debris wrapped around the rake teeth of the bar screen body 1. This not only reduces the workload of the workers, but also greatly improves the cleaning efficiency of the bar screen body 1.

[0033] In a preferred embodiment, the blade holder 203 has an inclined structure, with its high end positioned away from the fixing rod 202 and its low end positioned close to the fixing rod 202. This allows the cleaning blade 204 to gradually come into contact with the debris wrapped around the rake teeth of the bar screen body 1, squeezing and cutting off the debris to achieve a cleaning effect.

[0034] As a preferred embodiment, the cleaning blade 204 has a V-shaped surface on the side away from the blade holder 203. This facilitates the cleaning blade 204 in cleaning debris from the rake teeth of the bar screen body 1 on both sides.

[0035] As a preferred embodiment, the fixing component 3 includes a guide plate 301, a guide groove 302, a threaded groove 303, and a screw 304; two guide plates 301 are symmetrically fixed at both ends of the fixing rod 202; guide grooves 302 are provided on the opposite surfaces of the two fixing plates 201; wherein, the guide plates 301 and the guide grooves 302 are slidably engaged; two threaded grooves 303 are symmetrically provided at both ends of the fixing rod 202; the screw 304 passes through the fixing plate 201, and the end of the screw 304 passes through the guide plate 301 and is threadedly connected to the threaded groove 303. This utility model, by setting a guide plate 301, a guide groove 302, a threaded groove 303, and a screw 304, allows the screw 304 to be rotated with a tool, thus disengaging it from the threaded groove 303. Subsequently, the fixed rod 202 is moved, causing the guide plate 301 to slide within the guide groove 302 until the guide plate 301 disengages from the guide groove 302. This allows the fixed rod 202 to be disassembled, facilitating the replacement of the fixed rod 202, the blade holder 203, and the cleaning blade 204. This ensures the cleaning efficiency of the cleaning blade 204 in removing debris entangled on the rake teeth of the bar screen body 1.

[0036] In a preferred embodiment, the sliding assembly 4 includes a sliding groove 401 and a sliding block 402; the blade holder 203 has a sliding groove 401 on the side near the cleaning blade 204; the sliding block 402 is fixed on the side of the cleaning blade 204 near the blade holder 203; wherein the sliding block 402 is slidably engaged with the sliding groove 401; wherein the sliding block 402 has a T-shaped structure, and the T-shaped surface of the sliding block 402 is set away from the direction of the cleaning blade 204; when the end face of the guide plate 301 contacts the inner wall of the guide groove 302, the screw 304 can be threadedly connected to the threaded groove 303. This invention, by setting a sliding groove 401 and a sliding block 402, utilizes the sliding engagement between the sliding block 402 and the sliding groove 401. The sliding block 402 is configured with a T-shaped structure, and the T-shaped surface of the sliding block 402 is positioned away from the cleaning blade 204. This not only allows the cleaning blade 204 to be replaced separately after the fixing rod 202 is removed, greatly reducing the cost of replacing the cleaning blade 204, but also increases the contact area between the sliding block 402 and the sliding groove 401, improving the friction between them and making the connection between the sliding block 402 and the sliding groove 401 more stable, thereby ensuring the stability of the cleaning blade 204 installation.

[0037] The bar screen body 1 is a conventional instrument. Its working principle, size and model are not related to the problem solved by this application, so they will not be described in detail. The control method of this utility model is through a controller. The control circuit of the controller can be implemented by a person skilled in the art through simple programming. The power supply is also common knowledge in the art. Furthermore, this utility model is mainly used to protect mechanical devices, so the control method and circuit connection will not be explained in detail.

[0038] Working principle:

[0039] When using this new type of bar screen for sewage treatment, firstly, the bar screen body 1 is fixed in a suitable position. Then, the bar screen body 1 is started, so that the rake teeth on the bar screen body 1 can clean the debris in the water. When the rake teeth of the bar screen body 1 are driven, the debris wrapped around the rake teeth of the bar screen body 1 will first come into contact with the cleaning blade 204 from the high end to the low end of the cleaning blade 204. The debris wrapped around the rake teeth of the bar screen body 1 is squeezed and cut by the cleaning blade 204, so that the cleaning blade 204 can clean the debris wrapped around the rake teeth of the bar screen body 1.

[0040] When replacing the cleaning blade 204, rotate the screw 304 with a tool to disengage it from the threaded groove 303. Then, move the fixing rod 202 to slide the guide plate 301 within the guide groove 302 until the guide plate 301 disengages from the guide groove 302. Next, move the cleaning blade 204 upwards to slide the sliding block 402 upwards within the sliding groove 401 until the sliding block 402 disengages from the sliding groove 401. At this point, the disassembly of the cleaning blade 204 is complete. When installing the cleaning blade 204, insert the sliding block 402 into the sliding groove 401. Within the groove 401, slide the sliding block 402 in the opposite direction until the end face of the sliding block 402 contacts the inner wall of the groove 401. Then, insert the guide plate 301 into the guide groove 302 and slide the guide plate 301 in the opposite direction until the end face of the guide plate 301 contacts the inner wall of the guide groove 302. Subsequently, rotate the screw 304 in the opposite direction using a tool to thread the screw 304 into the threaded groove 303 until the end face of the screw 304 contacts the inner wall of the threaded groove 303. At this point, the replacement of the cleaning blade 204 is completed.
