Description

[0002] In the current sewage treatment process, as a key pretreatment device, the grille is widely used at the inlet of sewage lift pump stations or regulating ponds to intercept and remove larger suspended solids, floating objects, and particulate matters in sewage, such as branches, plastic bags, stones, etc., to prevent these impurities from entering the subsequent treatment units and causing blockages or equipment damage.

[0003] However, in actual applications, over time, the impurities intercepted by the grille will gradually accumulate in front of or on one side of the grille. If not cleaned in time, it will seriously affect the sewage flow efficiency, and even cause the grille to be completely blocked, thereby affecting the normal operation of the entire sewage treatment system.

[0004] Generally, the impurities on the grille rely mainly on manual fishing and cleaning. This method not only has a large labor intensity and low efficiency. Frequent manual cleaning and the low-efficiency operation of the equipment not only increase the labor cost, but also may cause increased equipment wear, shorten the service life, and thus increase the overall maintenance cost.

[0005] In view of the above problems, an interception device for sewage treatment is now designed. Utility Model Content

[0038] To make the objectives, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application. Apparently, the described embodiments are some but not all of the embodiments of the present application. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present application without creative efforts shall fall within the scope of protection of the present application.

[0039] The embodiments of the present application provide an interception device for sewage treatment, which can solve the problem that in the related art, impurities will gradually accumulate in front of or on one side of the existing grille during long-term use, affecting the sewage flow efficiency.

[0040] Please refer to Figures 1-3 , an interception device for sewage treatment includes: an inlet 1 of the sewage tank, a material turning mechanism 3, a recovery net 4 and a lifting mechanism 5. A grille 2 for blocking impurities is arranged inside the inlet 1 of the sewage tank; the material turning mechanism 3 is arranged on one side of the grille 2, and the material turning mechanism 3 is used for turning the impurities blocked in front of the grille 2; the material turning mechanism 3 includes: two groups of oppositely arranged mounting members 31, a driving motor 32 arranged on one of the mounting members 31, and a material turning drum 33 connected to the output shaft of the driving motor 32; the recovery net 4 is arranged at the bottom of the mounting member 31 and is used for collecting the impurities blocked in front of the grille 2; the lifting mechanism 5 is arranged on the inlet 1 of the sewage tank and is used for controlling the lifting of the material turning mechanism 3; the lifting mechanism 5 includes a gantry 51 arranged on the inlet 1 of the sewage tank and a lifting member 52 arranged on the gantry 51. The lifting member 52 is connected to the mounting member 31 and is used for controlling the lifting of the mounting member 31.

[0041] Impurity interception: When sewage enters through the inlet 1 of the sewage tank, it is first intercepted by the internal grille 2. The design of the grille effectively prevents larger solid impurities such as garbage and leaves from entering the inside of the sewage tank, protecting the normal operation of subsequent treatment equipment.

[0042] Impurity turning: When the impurities accumulated in front of the grille 2 reach a certain level, the material turning mechanism 3 starts to work. The driving motor 32 is started to drive the turning drum 33 to rotate. The rotational movement of the drum causes the impurities in front of the grille 2 to be turned, which helps prevent the impurities from accumulating too densely and causing blockages, and promotes the impurities to fall better into the recovery net 4.

[0043] Impurity recovery: The turned impurities fall into the recovery net 4 installed at the bottom of the mounting member 31 under the dual action of gravity and the pushing of the drum. The design of the recovery net 4 facilitates the centralized collection of impurities, which is convenient for subsequent cleaning and treatment.

[0044] Lifting: To maintain or adjust the position of the material turning mechanism 3, the lifting mechanism 5 controls the overall lifting of the mounting member 31 and the material turning mechanism 3 thereon, so as to maintain the turning drum 33 and, at the same time, conduct subsequent recovery treatment on the impurities collected by the recovery net 4.

[0045] Through the effective interception of the grille 2 and the turning action of the material turning mechanism 3, the large impurities entering the inside of the sewage tank are significantly reduced, the burden on the subsequent treatment equipment is alleviated, and the efficiency of the entire sewage treatment system is improved.

[0046] The regular turning of the material turning mechanism 3 can prevent the excessive accumulation of impurities in front of the grille 2, avoid the problem of poor sewage flow caused by blockages, and ensure the continuity and stability of sewage treatment.

[0047] The setting of the recovery net 4 facilitates the centralized collection and treatment of impurities. At the same time, the lifting mechanism 5 enables the material turning mechanism 3 and the recovery net 4 to be lifted conveniently, which is convenient for daily maintenance and also convenient for cleaning and recycling the blocked impurities.

[0048] This device aims to reduce manual intervention, lower energy consumption, and at the same time, by effectively intercepting and treating impurities, reduce secondary pollution to the environment, which conforms to the environmental protection concept.

[0049] Specifically, as Figure 3 and Figure 4 shown, in this implementation, the mounting member 31 described includes: slide rails 311 oppositely arranged on the gantry 51; a support disk 312 slidably arranged on the slide rails 311; a fixed block 313 arranged on the support disk 312. The driving motor 32 is arranged on one side of the fixed block 313 away from the support disk 312

[0050] The slide rails 311 are oppositely arranged on the gantry 51, providing a stable track for the lifting and horizontal movement of the mounting member 31. The design of the slide rails ensures the smoothness and accuracy of the mounting member 31 during movement.

[0051] The support plate 312 is slidably arranged on the slide rail 311. As the main load-bearing component of the mounting member 31, it is responsible for supporting the fixed block 313 and the driving motor 32 and the material turning drum 33 thereon. The sliding fit between the support plate 312 and the slide rail 311 enables the mounting member 31 to move vertically along the slide rail.

[0052] The fixed block 313 is arranged on the support plate 312 and is used to connect the lifting mechanism 5 and the recovery net 4.

[0053] During the installation process, first fix the slide rail 311 on the gantry 51, then slidably install the support plate 312 on the slide rail 311, and install the fixed block 313 on the support plate 312. The position and angle of the fixed block 313 should be adjusted according to actual needs to ensure the normal operation of the driving motor 32 and the material turning drum 33.

[0054] In one embodiment, as Figure 3 shown, the material turning drum 33 includes: a drum 331 connected to the output shaft of the driving motor 32; a plurality of material turning plates 332 arranged in a ring on the drum 331; and cutting knives 333 arranged on the material turning plates 332. The other end of the drum 331 is provided with a rotating shaft, and the rotating shaft is rotatably connected to the fixed block 313 opposite to the driving motor 32.

[0055] The material turning plate 332 is arc-shaped, hollow inside, and has an open end, and a plurality of through holes are provided on the material turning plate 332.

[0056] The material turning plate 332 is usually designed to be arc-shaped to better fit the surface of the drum 331 and produce a greater turning effect when rotating. The material turning plate 332 is hollow inside, which helps to reduce the weight of the material turning plate 332. The opening and the plurality of through holes on the drum 331 allow water flow and impurities to pass through when turning the impurities, reducing the resistance encountered by the material turning plate 332 during rotation.

[0057] The cutting knives 333 are arranged on the material turning plates 332. These cutting knives are usually designed to be sharp or have a cutting ability shape so that when the drum 331 rotates, they can cut larger impurities, making it easier for them to be processed by subsequent processing equipment or fall into the recovery net 4.

[0058] When the driving motor 32 is started, the drum 331 begins to rotate, driving the material turning plates 332 and the cutting knives 333 to move together. The arc-shaped design and rotational movement of the material turning plates 332 enable them to effectively turn the impurities in front of the grille 2, while the cutting knives 333 are responsible for cutting or crushing larger impurities. Through the action of gravity, the impurities fall into the recovery net 4 for collection and processing.

[0059] In one embodiment, as Figure 2 and Figure 5As shown, the lifting member 52 includes a mounting seat 521 provided on the gantry 51. A wire reel 522 is rotatably provided inside the mounting seat 521. A power source 523 is provided on the mounting seat 521. The power source 523 is connected to one end of the wire reel 522 and is used to drive the wire reel 522 to rotate. A cable 524 is wound around the wire reel 522. One end of the cable 524 is connected to the fixed block 313. The power source 523 includes a speed reducer and a second driving motor. The output end of the speed reducer is connected to one end of the wire reel. The second driving motor is provided on the speed reducer, and the output shaft of the driving motor is connected to the input shaft of the speed reducer.

[0060] The wire reel 522 is rotatably provided inside the mounting seat 521 and is the winding center of the cable 524.

[0061] When it is necessary to control the lifting of the tipping mechanism 3, the second driving motor in the power source 523 is started, and its power is transmitted to the wire reel 522 through the speed reducer to drive it to rotate. As the wire reel 522 rotates, the cable 524 will be wound or released, thereby driving the connected tipping mechanism 3 to lift and lower. By adjusting the rotation speed and direction of the second driving motor, precise control of the lifting speed and height of the tipping mechanism 3 can be achieved.

[0062] Preferably, as Figure 6 shown, the lifting member 52 in this embodiment further includes a connection head 525. The connection head 525 includes: a fixed disk 5251 connected to the cable 524; two split connection rods 5252 oppositely provided at the bottom of the fixed disk 5251. The two split connection rods 5252 are in a V shape. The other end of the split connection rod 5252 is connected to the top of the fixed block 313.

[0063] The fixed disk 5251, as the main load-bearing component of the connection head 525, is responsible for transmitting the tension of the cable 524 to the split connection rods 5252 and further to the fixed block 313.

[0064] The two split connection rods 5252 are oppositely provided at the bottom of the fixed disk 5251 and are in a V shape. This design helps to disperse the tension transmitted by the cable 524 and reduces the risk of single-point stress. The other end of the split connection rod 5252 is connected to the top of the fixed block 313. It not only transmits the tension of the cable 524 to the fixed block 313 but also enhances the connection stability and torsional resistance through its V-shaped structure.

[0065] The tension of the cable 524 is transmitted to the split connection rods 5252 through the fixed disk 5251 of the connection head 525, and then the split connection rods 5252 disperse the tension and transmit it to the fixed block 313. Since the split connection rods 5252 are in a V shape, they can effectively disperse the tension and enhance the connection stability. In this way, the tipping mechanism 3 can maintain stability and reliability during the lifting and lowering process.

[0066] As Figure 2 shown, in this embodiment, the recovery net 4 includes a bracket 41 disposed at the bottom of the fixed block 313, and a net box 42 disposed at the bottom of the two brackets 41. The net box 42 is used to collect the blocked impurities. The bracket 41 is triangular, and the upper part of the net box 42 is open for receiving the settled impurities.

[0067] The main function of the bracket 41 is to support the net box 42 and ensure that it can be stably placed in the required position to collect the dropped impurities.

[0068] The net box 42 is disposed at the bottom of the two brackets 41 to form a semi-closed space. The main function of the net box 42 is to collect the impurities blocked and dropped by the turning mechanism 3. These impurities may include various solid wastes, floating objects, etc. After being intercepted by the turning mechanism 3, they fall into the net box 42 by gravity.

[0069] The net box 42 is usually made of corrosion-resistant and wear-resistant materials to ensure that it can be used in a harsh water quality environment for a long time without being damaged. At the same time, the mesh size of the net box also needs to be designed according to actual needs to ensure that the target impurities can be effectively intercepted and collected.

[0070] Furthermore, as Figure 4 shown, in this embodiment, a chute is provided on the slide rail 311, and a slider adapted to the chute is provided on the side of the support plate 312 away from the fixed block 313; a pick-up slot 6 communicating with the chute is provided on the slide rail 311, and the pick-up slot 6 is used to take out the slider from the inside of the chute.

[0071] The chute provided on the slide rail 311 and the slider provided on the support plate 312 are closely matched to ensure that the support plate 312 can slide smoothly and steadily on the slide rail 311. This design reduces the friction and wear during the movement, improving the durability and stability of the entire structure.

[0072] The chute takes into account the lateral force that the support plate 312 may encounter during the sliding process. Therefore, the shape and size of the chute should be able to provide good anti-rollover ability to prevent the support plate 312 from shifting or tilting during the sliding.

[0073] The pick-up slot 6 communicates with the chute. When the lifting mechanism 5 works, the cable 524 will pull the slider to move along the chute to the position of the pick-up slot 6. At this time, the slider can be taken out from the inside of the chute, so that the support plate 312 is no longer restricted by the slide rail 311.

[0074] After the slider is taken out, the staff can easily move the fixed disk 5251 and the tapping rod 5252, and then pour out the impurities inside the recovery net 4, greatly simplifying the operation process of impurity recovery and improving work efficiency.

[0075] After the impurity recovery is completed, the staff only needs to restore the fixed disk 5251 and the tapping rod 5252 to their original positions and put the slider back into the chute, so that the support disk 312 is restricted by the slide rail 311 again, preparing for the next work cycle.

[0076] In the description of the present application, it should be noted that the orientation or positional relationship indicated by terms such as "upper" and "lower" is based on the orientation or positional relationship shown in the drawings.
