Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, and in particular to a wastewater removal machine. Background Technology

[0002] As a solid-liquid separation machine, bar screens are increasingly used in industries such as sewage treatment, tap water supply, power plant cooling, and water conservancy and irrigation due to their reliable operation and strong cleaning ability. They are gradually replacing manual bar screens and have become one of the most important pieces of equipment in the pretreatment stage of the water treatment industry.

[0003] The working principle of the bar screen is based on a unique rake chain structure. Driven by a motor reducer, the rake chain rotates against the direction of water flow. When the rake chain reaches the top of the equipment, the guide wheel and curved rail cause a relative self-cleaning motion between each set of rake teeth. Most of the solid matter falls off due to gravity, while the other part is cleaned by the reverse motion of the sweeper. This continuous automatic interception and removal of debris ensures smooth water flow and effectively removes pollutants from the water.

[0004] Prolonged use of existing bar screen cleaning machines can lead to clogging of the bar screen, reducing its normal water intake efficiency and even preventing sewage from passing through. It also increases the difficulty of cleaning debris from the bar screen and hinders the discharge of sewage from the machine. A bar screen cleaning machine mainly consists of a bar screen, drive unit, frame, and sludge hopper. When sewage flows through the bar screen, large solid particles and suspended matter are trapped, forming a sludge layer. The drive unit then activates, moving the sludge hopper along the bar screen to shovel the trapped solid waste into the sludge hopper. The sludge hopper then transports the collected solid waste to a designated treatment area for further processing. However, excessive moisture and weight in the sludge hopper can affect the passage efficiency of the bar screen, reducing the overall efficiency of the bar screen cleaning machine. Utility Model Content

[0005] In view of the fact that the existing bar screen cleaning machines do not have a cleaning function and are prone to clogging of the bar screen, this utility model is proposed.

[0006] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a sewage treatment machine, including a frame, a cleaning box installed on the upper surface of the frame, and a cleaning component for cleaning the bar screen installed at the bottom of the cleaning box;

[0007] The cleaning assembly includes a first fixing plate installed at the bottom of the cleaning box. Two moving rods reciprocate linearly on the surface of the first fixing plate. Both ends of each moving rod are rotatably connected to a first rotating rod. A second rotating rod is rotatably connected to the middle of the first rotating rod. The bottom of the second rotating rod is rotatably connected to the surface of the first fixing plate. The top ends of the first and second rotating rods are rotatably connected to a second fixing plate. A sliding hole is provided on one side of the second fixing plate to facilitate the insertion of the second rotating rod. A cleaning roller is rotatably connected to the inner wall of the second fixing plate.

[0008] As a preferred embodiment of the wastewater cleaning machine of this utility model, a No. 1 motor is fixedly connected to the upper surface of the cleaning box, a No. 1 transmission rod is splined to the output end of the No. 1 motor, a No. 1 turntable is fixedly connected to one end of the No. 1 transmission rod, and a No. 2 turntable is rotatably connected to the surface of the frame.

[0009] In a preferred embodiment of the wastewater treatment machine of this utility model, belts are wrapped around the surfaces of the first and second turntables, two transmission rollers are rotatably installed between the two opposite inner sidewalls of the frame, wherein one transmission roller is fixedly connected to one side of the second turntable, and a conveyor belt is fitted between the two transmission rollers.

[0010] As a preferred embodiment of the wastewater treatment machine of this utility model, a filter hole is provided on one side of the surface of the conveyor belt, and a grid filter screen is fixedly connected to the inner surface of the filter hole. A toothed rake that can catch garbage is installed on the side of the conveyor belt away from the filter hole. A threaded fixing plate is provided on one side of the surface of the first fixing plate, and a threaded rotating rod is threadedly connected to the surface of the threaded fixing plate.

[0011] As a preferred embodiment of the wastewater cleaning machine of this utility model, wherein: a second motor with its output end splinedly connected to one end of a threaded rotating rod is installed on the surface of the first fixed plate, and a third motor with its output end splinedly connected to one end of a cleaning roller is installed on the surface of the second fixed plate.

[0012] In a preferred embodiment of the wastewater cleaning machine of this utility model, wastewater plates are installed on both sides of the second fixing plate away from the cleaning roller, and the surface of the cleaning roller is provided with rubber cleaning strips.

[0013] The beneficial effects of this utility model are:

[0014] This utility model is equipped with a cleaning component. The rotation of the threaded rod drives two rotating rods to rotate in a cross shape. The second rotating rod moves in the sliding hole, thereby driving the second fixing plate to move up and down on the first fixing plate. This serves to store and assist in raising and lowering the height of the cleaning grid filter. At the same time, the cleaning roller, the sewage plate and the rubber cleaning strip work together. The rubber cleaning strip on the cleaning roller can quickly rotate and sweep the garbage on the grid filter. The sewage plate can block the wastewater splashed out when the rubber cleaning strip sweeps the grid filter, avoiding excessive garbage on the grid filter and preventing blockage. Also, excessive moisture on the surface of the grid filter can easily affect the working efficiency of the cleaning machine. Attached Figure Description

Detailed Implementation

[0022] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. Example 1

[0023] Reference Figure 1-3This is the first embodiment of the present utility model, which provides a sewage cleaning machine, including a frame 1, a cleaning box 2 installed on the upper surface of the frame 1, and a cleaning component for cleaning the bar screen installed at the bottom of the cleaning box 2.

[0024] The cleaning assembly includes a first fixing plate 3 installed at the bottom of the cleaning box 2. Two moving rods 6 reciprocate linearly on the surface of the first fixing plate 3. The two ends of the moving rods 6 are rotatably connected to a first rotating rod 7. The middle of the first rotating rod 7 is rotatably connected to a second rotating rod 8. The bottom of the second rotating rod 8 is rotatably connected to the surface of the first fixing plate 3. The top of the first rotating rod 7 and the second rotating rod 8 are rotatably connected to a second fixing plate 9. A sliding hole 10 is provided on one side of the second fixing plate 9 to facilitate the insertion of the second rotating rod 8. A cleaning roller 11 is rotatably connected to the inner wall of the second fixing plate 9. The cleaning roller 11 rotates under the drive of a third motor and sweeps away excess debris on the grid filter screen 14. Example 2

[0025] Reference Figure 1-4This is the second embodiment of the present invention, which differs from the first embodiment in that: a No. 1 motor 12 is fixedly connected to the upper surface of the cleaning box 2; a No. 1 transmission rod is splinedly connected to the output end of the No. 1 motor 12; a No. 1 turntable is fixedly connected to one end of the No. 1 transmission rod; a No. 2 turntable is rotatably connected to the surface of the frame 1; a belt is wrapped around the surfaces of the No. 1 and No. 2 turntables; two transmission rollers are rotatably installed between two opposite inner sidewalls of the frame 1; one of the transmission rollers is fixedly connected to one side of the No. 2 turntable; a conveyor belt 13 is wrapped between the two transmission rollers; a filter hole is opened on one side of the surface of the conveyor belt 13; a grid filter screen 14 is fixedly connected to the inner surface of the filter hole; the grid filter screen 14 is made of soft metal material, so it can easily rotate around the conveyor belt 13; a toothed rake 15 that can catch garbage is installed on the side of the conveyor belt 13 away from the filter hole. The system includes a No. 1 motor 12, a No. 1 turntable, a No. 2 turntable, a belt, and transmission rollers. When the operator starts the No. 1 motor 12, the No. 1 turntable rotates in conjunction with the belt. The second turntable rotates, driving the transmission roller to rotate, causing the conveyor belt 13 to rotate. The bar screen 14 is used to intercept large suspended and floating objects in the sewage, preventing them from entering subsequent treatment equipment and causing blockage or damage. The toothed rake 15 is used to efficiently separate pollutants in the water without frequent manual intervention, greatly improving work efficiency. A threaded fixing plate 4 is provided on one side of the surface of the first fixing plate 3. A threaded rotating rod 5 is threadedly connected to the surface of the threaded fixing plate 4. A second motor 16 is installed on the surface of the first fixing plate 3, with its output end splinedly connected to one end of the threaded rotating rod 5. A third motor is installed on the surface of the second fixing plate 9, with its output end splinedly connected to one end of the cleaning roller 11. Sewage plates 17 are installed on both sides of the second fixing plate 9, away from the cleaning roller 11. The sewage plates 17 are used to block sewage and sludge splashed during cleaning. Rubber cleaning strips 18 are provided on the surface of the cleaning roller 11. There are several rubber cleaning strips 18, which are used to clean the garbage on the bar screen 14 more efficiently.

[0026] The working process of this utility model is as follows:

[0027] The staff starts motor 12, which drives turntable 1 and belt to rotate, and simultaneously drives turntable 2 to rotate, causing conveyor belt 13 to move. As conveyor belt 13 moves, rake 15 can hook garbage in the water, which can move the garbage in the water and finally dump it. When rake 15 moves the garbage, the wastewater in the garbage will flow out from the grid filter screen 14. Not only water but also fallen garbage will flow out. As the machine works for a long time, the garbage on the grid filter screen 14 will accumulate more and more.

[0028] The operator can start the second motor, and the threaded rotating rod 5 rotates on the threaded fixed plate 4, causing the moving rod 6 to move and drive the first rotating rod 7 to rotate. At the same time, one end of the second rotating rod 8 moves in the sliding hole 10 on the second fixed plate 8, causing the first rotating rod 7 to rotate and drive the second rotating rod 8 to rotate in a cross shape, which makes it easy for the operator to adjust the height. The operator can then start the third motor again, and the cleaning roller 11 drives the rubber cleaning strip 17 to roll, which can clean the garbage on the grid filter screen 14. The sewage plate 17 can block the wastewater or sludge splashed during cleaning.

[0029] The remaining structure is the same as that in Example 1.

[0030] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
