An inlet garbage filtering device for sewage treatment

Abstract

This utility model discloses an inlet garbage filtration device for sewage treatment, belonging to the field of sewage treatment technology. It addresses the problems of filter screens easily becoming clogged during garbage interception and the filtered garbage still containing a large amount of sewage requiring secondary treatment. The device includes a housing with an inlet trough fixedly connected to the top. A filtration mechanism is installed inside the housing. Through this filtration mechanism, sewage is poured into the housing from the inlet trough and falls onto the surface of a conveyor belt. Solid garbage is filtered by the conveyor belt and remains on the surface. Multiple baffles cooperate with the conveyor belt to transport the solid garbage obliquely upwards. Liquid in the sewage flows directly from the through-holes on the surface of the conveyor belt to the bottom of the housing. Solid garbage, after moving to the top of the conveyor belt, falls into a squeezing groove. Multiple scraper rods further push the garbage hanging on the baffles into the squeezing groove, preventing garbage accumulation on the surface of the conveyor belt, thereby preventing clogging and affecting filtration efficiency.

Description

Technical Field

[0001] This utility model belongs to the field of wastewater treatment technology, and specifically relates to an influent garbage filtration device for wastewater treatment. Background Technology

[0002] Wastewater treatment is the process of purifying wastewater to meet the water quality requirements for discharge into a water body or for reuse. Wastewater treatment is widely used in various fields such as construction, agriculture, transportation, energy, petrochemicals, environmental protection, urban landscaping, medical care, and catering, and is increasingly entering the daily lives of ordinary people. In the wastewater treatment process, the first step is to filter out solid waste from the wastewater, and then further recycle and reuse it.

[0003] The prior art, patent publication number CN211025347U, describes an inlet garbage filtration device for a wastewater treatment plant. This patent includes an outlet and a filter screen. The filter screen is bolted to the left side of the outlet. Hinges are rotatably connected to both sides of the outlet's inner wall via hinges. A straight toothed rack is bolted to the outside of the outlet, and a support is movably connected to the outside of the outlet. A screen plate is bolted to the left side of the support, a roller is bolted to the right inner end of the support, and a protective cover is bolted to the left inner end of the support. This device can solve the unified collection and filtration of garbage and wastewater, enabling garbage treatment to be performed more frequently and reducing manpower input. However, in practical use, it still has the following shortcomings: From a practical standpoint, this device only intercepts garbage on the wastewater, which can easily cause filter screen clogging over time. Furthermore, personnel need to regularly clean the intercepted garbage. The intercepted garbage still contains a large amount of wastewater, and cleaning this garbage may cause secondary pollution, increasing the difficulty of cleaning and the risk of environmental pollution.

[0004] Therefore, there is a need for an influent garbage filtration device for sewage treatment to solve the problems in the existing technology where the filter screen is easily clogged when intercepting garbage and the filtered garbage still contains a large amount of sewage that needs to be treated again. Utility Model Content

[0005] The purpose of this invention is to provide an influent garbage filtration device for sewage treatment, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an inlet garbage filtration device for sewage treatment, comprising a box, an inlet trough fixedly connected to the top of the box, a filtration mechanism provided inside the box, a squeezing groove fixedly connected to one side of the inner wall of the box, a hydraulic cylinder fixedly connected to one side of the box, a pressure plate fixedly connected to the output end of the hydraulic cylinder through the box, an outlet fixedly connected to the bottom of the box, a door rotatably connected to one side of the box, and a handle fixedly connected to the outside of the door.

[0007] It should be noted in the solution that a tank cover is rotatably installed on the top of the water inlet tank.

[0008] It is further worth noting that the filtration mechanism includes a drive roller rotatably connected to the inner walls of the front and rear ends of the housing and multiple driven rollers rotatably connected to the inner walls of the front and rear ends of the housing. A conveyor belt is installed on the outer wall of the drive roller and the outer walls of the multiple driven rollers. Multiple sets of stop teeth are fixedly connected to the outer wall of the conveyor belt. A rotating shaft is rotatably connected between the inner walls of the front and rear ends of the housing. A first synchronous pulley is fixedly connected through the housing on one side of the drive roller, and a second synchronous pulley is fixedly connected through the housing on one side of the rotating shaft. A synchronous belt is installed on the outer wall of the first synchronous pulley and the outer wall of the second synchronous pulley. A convex frame is fixedly connected to the outer side of the housing, and a servo motor is fixedly connected to the outer side of the convex frame. Multiple tube sleeves are fixedly connected to the outer wall of the rotating shaft, and multiple dirt-dispensing rods are fixedly connected to the outer walls of each of the multiple tube sleeves.

[0009] Furthermore, it should be noted that the front and rear ends of the outer wall of the conveyor belt are fixedly connected with retaining edges.

[0010] In a preferred embodiment, the output end of the servo motor is fixedly connected to the rotating shaft.

[0011] In a preferred embodiment, the multiple sets of the dirt-dispensing rods and the multiple sets of baffles are distributed alternately.

[0012] In a preferred embodiment, the bottom of the extrusion groove is provided with multiple through holes.

[0013] As a preferred embodiment, an observation window is provided inside the box door.

[0014] Compared with the prior art, the influent garbage filtration device for sewage treatment provided by this utility model has at least the following beneficial effects:

[0015] (1) By setting up a filtration mechanism, sewage is poured into the tank from the inlet tank and falls onto the surface of the conveyor belt. Solid waste is filtered by the conveyor belt and remains on the surface. Multiple baffles cooperate with the conveyor belt to transport the solid waste obliquely upward. The liquid in the sewage flows directly from the through holes on the surface of the conveyor belt to the bottom of the tank. The solid waste falls into the squeezing groove after moving to the top of the conveyor belt. Multiple scraper bars further push the waste hanging on the baffles into the squeezing groove to prevent the waste from accumulating on the surface of the conveyor belt, thereby preventing blockage and affecting the filtration efficiency.

[0016] (2) By setting up a squeezing tank, when solid waste enters the squeezing tank, the hydraulic cylinder is opened to drive the pressure plate to move inward, squeezing out water from the solid waste on the squeezing tank. The sewage flows from the bottom of the squeezing tank to the bottom of the box, further realizing solid-liquid separation, reducing the residual sewage in the solid waste, making it cleaner during treatment, and effectively avoiding secondary pollution.

[0022] The present invention will be further described below with reference to the embodiments.

[0023] Please see Figures 1-4 This utility model provides an inlet garbage filtration device for sewage treatment, including a box body 1, an inlet tank 2 fixedly connected to the top of the box body 1, a filtration mechanism 3 installed inside the box body 1, a squeezing groove 4 fixedly connected to one side of the inner wall of the box body 1, a hydraulic cylinder 5 fixedly connected to one side of the box body 1, a pressure plate 6 fixedly connected to the output end of the hydraulic cylinder 5 through the box body 1, a water outlet 7 fixedly connected to the bottom of the box body 1, a box door 8 rotatably connected to one side of the box body 1, and a handle 9 fixedly connected to the outside of the box door 8.

[0024] Further as Figure 1 , Figure 2 and Figure 3As shown, it is worth noting that a cover is rotatably installed on the top of the inlet tank 2. The cover can prevent external debris, pollutants, or other unwanted substances from entering the inlet tank 2, thereby ensuring the purity of the incoming water and preventing the garbage inside the inlet tank 2 from coming into contact with the external environment. At the same time, odors are generated during the sewage treatment process. Installing the cover can effectively reduce the spread of odors and maintain the cleanliness and comfort of the surrounding environment. The cover can also prevent water from overflowing in the inlet tank due to operation or external factors, thus avoiding environmental pollution or equipment damage.

[0025] Further as Figure 3 As shown, it is worth noting that the bottom of the extrusion tank 4 has multiple through holes. These through holes ensure that the wastewater generated after the solid waste is extruded can be quickly discharged, further realizing solid-liquid separation.

[0026] Further as Figure 1 , Figure 2 and Figure 3 As shown, it is worth noting that an observation window is provided inside the door 8. The observation window allows the operator to directly observe the working status inside the box 1, such as the filtration effect, the garbage accumulation, and whether there are any abnormalities. This facilitates timely detection of problems. The operator can check the internal situation without opening the door 8, avoiding the trouble and time waste caused by having to open the door 8 every time for inspection, thus improving work efficiency.

[0027] As can be seen from the above working process: by setting up the squeezing tank 4, when solid waste enters the squeezing tank 4, the hydraulic cylinder 5 is opened to drive the pressure plate 6 to move inward, squeezing the solid waste on the squeezing tank 4 to squeeze out water. The sewage flows from the bottom of the squeezing tank 4 into the bottom of the box 1, further realizing solid-liquid separation, reducing the residual sewage in the solid waste, making it cleaner during treatment, and effectively avoiding secondary pollution.

[0028] Further as Figure 4As shown, it is worth noting that the filter mechanism 3 includes a drive roller 301 rotatably connected to the inner walls of the front and rear ends of the housing 1, and multiple driven rollers 302 rotatably connected to the inner walls of the front and rear ends of the housing 1. A conveyor belt 303 is installed on the outer wall of the drive roller 301 and the outer walls of the multiple driven rollers 302. Multiple sets of stop teeth 304 are fixedly connected to the outer wall of the conveyor belt 303. A rotating shaft 305 is rotatably connected between the inner walls of the front and rear ends of the housing 1. A first synchronous pulley 306 is fixedly connected to one side of the drive roller 301 through the housing 1, and a second synchronous pulley 307 is fixedly connected to one side of the rotating shaft 305 through the housing 1. A synchronous belt 308 is installed on the outer wall of the first synchronous pulley 306 and the outer wall of the second synchronous pulley 307. A convex frame 309 is fixedly connected to the outer side of the housing 1, and a servo motor 3 is fixedly connected to the outer side of the convex frame 309. 10. Multiple sleeves 311 are fixedly connected to the outer wall of the rotating shaft 305. Multiple sludge-dispensing rods 312 are fixedly connected to the outer wall of each sleeve 311. Through the filter mechanism 3, sewage is poured into the box 1 from the inlet tank 2 and falls onto the surface of the conveyor belt 303. Solid waste is filtered by the conveyor belt 303 and remains on the surface. Multiple baffles 304 cooperate with the conveyor belt 303 to transport the solid waste obliquely upward. The liquid in the sewage flows directly from the through holes on the surface of the conveyor belt 303 to the bottom of the box 1. The solid waste falls into the squeezing groove 4 after moving to the top of the conveyor belt 303. The multiple sludge-dispensing rods 312 further push the waste hanging on the baffles 304 into the squeezing groove 4 to prevent the waste from accumulating on the surface of the conveyor belt 303, thereby preventing blockage and affecting the filtration efficiency.

[0029] Further as Figure 4 As shown, it is worth noting that the conveyor belt 303 has fixed side guards at both the front and rear ends of its outer wall. These side guards effectively prevent solids from accidentally slipping during the conveying process, ensuring the cleanliness and effectiveness of the filtration process. Simultaneously, the side guards help ensure that solid waste on the conveyor belt 303 does not deviate from the predetermined trajectory during transmission, maintaining stable material flow and preventing instability caused by deviation. The side guards also provide additional physical support, helping the conveyor belt 303 to carry more waste, reducing the risk of deformation or damage due to excessive load, and extending the service life of the equipment.

[0030] Further as Figure 4 As shown, it is worth noting that the output end of the servo motor 310 is fixedly connected to the rotating shaft 305, ensuring that the servo motor 310 can drive the rotating shaft 305 to rotate stably. At the same time, it provides driving force for the movement of the conveyor belt 303 and the rotation of the dirt-dispelling rod 312 to dispel dirt, thus avoiding the accumulation of garbage, ensuring the continuous operation of the equipment and preventing blockage.

[0031] Further as Figure 4As shown, it is worth noting that the multiple sets of dirt-removing rods 312 and multiple sets of baffle teeth 304 are staggered, which allows the dirt-removing rods 312 to come into contact with the dirt on the conveyor belt 303 more effectively, thereby removing the dirt more thoroughly from the conveyor belt 303 and the baffle teeth 304, preventing dirt accumulation, and ensuring the smooth operation of the filtration device.

[0032] This solution has the following working process: In actual use, sewage is poured into the tank 1 from the inlet tank 2 and falls onto the surface of the conveyor belt 303. Solid waste is filtered by the conveyor belt 303 and remains on the surface. The servo motor 310 is turned on to drive the rotating shaft 305 to rotate. Under the action of the synchronous belt 308, the drive roller 301 starts to rotate. Multiple baffles 304 cooperate with the conveyor belt 303 to transport the solid waste diagonally upward. The liquid in the sewage flows directly from the through holes on the surface of the conveyor belt 303 to the bottom of the tank 1. As the solid waste moves to the top of the conveyor belt 303, it falls into the squeezing trough 4. At the same time, the rotating shaft 305 drives multiple sets of pipe sleeves 311 to rotate, and multiple dirt-pushing rods 312 further push the waste hanging on the stop teeth 304 into the squeezing trough 4. After the solid waste enters the squeezing trough 4, the hydraulic cylinder 5 is opened to drive the pressure plate 6 to move inward, squeezing the solid waste on the squeezing trough 4 to squeeze out water. The sewage flows from the bottom of the squeezing trough 4 into the bottom of the box 1. After the filtration is completed, the box door 8 is opened to take out the squeezed solid waste.

[0033] In summary: By setting up the filtration mechanism 3, waste is prevented from accumulating on the surface of the conveyor belt 303, thus preventing blockage and affecting filtration efficiency; by setting up the squeezing tank 4, solid-liquid separation is further achieved, reducing residual wastewater in solid waste, making it cleaner during treatment, and effectively avoiding secondary pollution.
