Description

Technical Field

[0001] This utility model belongs to the technical field of sewage treatment equipment, specifically relating to a fully buried manual bar screen cleaning machine. Background Technology

[0002] Wastewater treatment screens are specialized water treatment devices that can continuously and automatically intercept and remove debris of various shapes from fluids. They are typically placed at an angle in wastewater tanks to block and retain large suspended or floating solids in wastewater and are widely used in urban wastewater treatment.

[0003] Currently, wastewater treatment plants commonly use two types of bar screens: mechanical bar screens and manual bar screens. Mechanical bar screens are suitable for large-scale wastewater treatment plants with no investment restrictions and simple surrounding environments, while manual bar screens are suitable for smaller wastewater treatment plants in special locations, such as hospitals. Small wastewater treatment plants typically use underground wastewater tanks, which have deep bar screens. Manual cleaning of the bar screens is troublesome, and the screen residue has a strong odor. Placing the screen residue bins on the ground can easily impact the surrounding environment. Utility Model Content

[0004] The purpose of this utility model is to provide a fully buried manual bar screen cleaning machine to solve the problems of cumbersome manual bar cleaning operation and the environmental impact of placing the bar screen bucket on the ground.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0006] A fully buried manual bar screen cleaning machine includes a screenings bucket and a bar screen assembly. The screenings bucket can be detachably installed in a sewage tank. The bar screen assembly includes a bar screen, a manual rotating wheel, and a first chain. The bar screen is provided with several rake teeth. The lower end of the bar screen is placed at the bottom of the sewage tank, and the upper end of the bar screen is located above the screenings bucket. The first chain is engaged with the manual rotating wheel and the upper end of the bar screen. Rotating the manual rotating wheel can drive the rake teeth on the bar screen to rotate through the first chain.

[0007] Furthermore, the lower end and the upper end of the grid are respectively provided with a first transmission wheel and a second transmission wheel, and a second chain is meshed on the first transmission wheel and the second transmission wheel. Rake teeth are arranged on the second chain, and the first chain meshes with the second transmission wheel.

[0008] Furthermore, the bottom of the screenings bucket is provided with several drainage holes.

[0009] Furthermore, the top of the screenings bucket is provided with a lifting ring.

[0010] Furthermore, the bottom of the screenings bucket is provided with a channel steel support, and the two sides of the screenings bucket are provided with limiting rods. The channel steel support and the limiting rods are all fixed to the wall of the sewage tank.

[0011] Furthermore, the screenings bin is made of stainless steel, PVC, or PE corrosion-resistant material.

[0012] Compared with the prior art, the present invention has the following beneficial technical effects:

[0013] 1. This utility model places the screenings bucket below the slag outlet of the screen assembly. During the cleaning process, the manual rotating wheel is turned to drive the rake teeth on the screen to rotate, which conveys the screenings intercepted in the screen to the screenings bucket. Then, the lifting ring is pulled to lift the screenings bucket to the ground, completing the screenings dumping and transfer. The cleaning operation is simple, fast and efficient. The screenings bucket is placed in the sewage tank and will not affect the ground environment.

[0014] 2. This utility model has a simple structure and low construction cost. The manual screen does not consume electricity, thus saving energy and reducing consumption. By setting a drain hole at the bottom of the screen bucket, the water in the screen can be drained, eliminating the need for a separate screen dewatering device and further saving investment. It is suitable for small sewage treatment plants. Attached Figure Description

[0016] The following detailed description illustrates the specific implementation method:

[0017] The reference numerals in the accompanying drawings include:

[0019] Example

[0020] like Figure 1 As shown, a fully buried manual bar screen cleaning machine includes a screenings bucket 2 and a bar screen 5 assembly installed in a sewage tank 1.

[0021] The sewage tank 1 has an openable cover 11 installed on its top. A channel steel support 3 and two limiting rods 4 are fixed on the wall of the sewage tank 1. The screenings bucket 2 is placed between the channel steel support 3 and the two limiting rods 4. Multiple drainage holes are evenly opened at the bottom of the screenings bucket 2. Two lifting rings 21 are welded and fixed to the top of the screenings bucket 2. The screenings bucket 2 is made of stainless steel, PVC or PE material. By setting drainage holes at the bottom of the screenings bucket 2, the moisture of the screenings can be drained, eliminating the need for separate screenings dewatering equipment, saving costs. Stainless steel, PVC and PE materials have good corrosion resistance and can extend the service life of the screenings bucket 2.

[0022] The grating 5 assembly includes a grating 5, a manual rotating wheel 6, and a first chain 7. The lower end of the grating 5 is placed at the bottom of the sewage tank 1, and the upper end of the grating 5 is located above the screenings bucket 2. The lower end and the upper end of the grating 5 are respectively provided with a first drive wheel 51 and a second drive wheel 52. A second chain 53 is meshed on the first drive wheel 51 and the second drive wheel 52. Multiple rake teeth are evenly arranged on the second chain 53. The manual rotating wheel 6 can be set inside the sewage tank 1 or on the ground according to the actual situation. In this embodiment, the manual rotating wheel 6 is set inside the sewage tank 1, and the first chain 7 is meshed on the manual rotating wheel 6 and the second drive wheel 52.

[0023] During the cleaning process, manually rotating the manual wheel 6 drives the second chain 53 to rotate via the first chain 7 and the second transmission wheel 52. This causes the target teeth on the second chain 53 to transport the screenings on the grid 5 to the upper end of the grid 5, where they fall into the screenings bin 2. Once the screenings bin 2 is full, the lifting ring 21 lifts the screenings bin 2 to the ground, allowing the screenings inside to be dumped and transferred. The manual cleaning operation is simple, quick, and efficient. The screenings bin 2 is placed in the sewage tank 1. After the cleaning is completed, the cover plate 11 of the sewage tank 1 is placed on top to isolate the odor generated by the sewage tank 1, thus preventing any impact on the ground environment.

[0024] The manual bar screen provided in this embodiment has a simple structure and low construction cost. Furthermore, the manual bar screen 5 does not consume electricity, thus saving energy and reducing consumption, and further reducing the capital investment in the construction of the sewage tank 1.
