Description

Technical Field

[0001] This utility model relates to the technical field of impurity removal devices, specifically to a slag removal and purification device for composite carbon source production. Background Technology

[0002] Composite carbon sources are used for denitrification in wastewater treatment. During the production process, impurity particles may be present in the composite carbon source liquid. This is mainly due to the presence of impurity particles in the raw materials themselves, or due to incomplete reactions during enzymatic hydrolysis, fermentation, or chemical synthesis, resulting in insoluble precipitates. If these impurity particles enter the wastewater treatment system along with the carbon source, they can clog the dosing pumps, pipes, or aeration devices, leading to equipment malfunctions. Impurities can also dilute the effective carbon source concentration, reducing the denitrification capacity per unit volume of carbon source and thus decreasing the wastewater treatment capacity. Therefore, purification and impurity removal are necessary. The composite carbon source liquid is purified by using filtration equipment. The filter cartridge or filter screen filters out impurity particles. However, when using the filtration equipment, there are problems as mentioned in the authorization announcement number CN221333087U. Because the filter material (filter cartridge or filter screen) is difficult to disassemble, the filtered impurities are difficult to clean out of the filter material. If the impurity particles retained in the filter material are not cleaned in time, a large amount of filter residue will accumulate, affecting the subsequent slag removal and purification of the composite carbon source liquid. Utility Model Content

[0003] This invention addresses the problem of difficult-to-remove impurity particles retained in the filter material during the purification of composite carbon source liquids. It provides a slag removal and purification device for composite carbon source production, which can easily remove impurities and prevent a large amount of filter residue from accumulating in the filter cylinder, thus affecting the subsequent purification of the composite carbon source.

[0004] To solve the above problems, the technical solution of this utility model is: A slag removal and purification device for composite carbon source production includes a shell, the lower left and right ends of which are supported by support plates. It also includes a filter cylinder and a spiral plate. The shell is positioned with the left side higher than the right. The filter cylinder is coaxial with the shell, with its open end located inside the shell and connected to the closed end on the right side. The closed end of the filter cylinder penetrates the closed end on the left side of the shell. Filter holes are evenly distributed on the lower part of the peripheral wall of the filter cylinder inside the shell, and a slag outlet is provided on the lower part of the peripheral wall of the filter cylinder outside the shell. A liquid outlet end is fixed to the upper left end of the shell, connecting to the liquid inlet pipe of the filter cylinder. A drain pipe is fixed to the lower part of the closed end on the right side of the shell, with one end of the drain pipe connected to the shell and located between the filter cylinder and the peripheral wall of the shell. A rotating shaft is coaxially mounted inside the filter cylinder, and a motor is mounted on the shell to drive the rotating shaft. A spiral plate is fixedly mounted on the outer sleeve of the rotating shaft.

[0005] Furthermore, there is a gap between the outer wall of the filter cylinder and the inner wall of the housing, and the left closed end of the housing is provided with a connecting hole for the filter cylinder to pass through, and the outer wall of the filter cylinder is fixedly connected to the connecting hole.

[0006] Furthermore, the left end of the rotating shaft is rotatably connected to the closed end of the filter cylinder via a first sealed bearing, and the right end of the rotating shaft is rotatably connected to the right closed end of the housing via a second sealed bearing. A motor is fixed on the outer right side of the housing, and the output end of the motor is connected to the right end of the rotating shaft.

[0007] Furthermore, the outer edge of the spiral plate slides in contact with the inner wall of the filter cylinder, the spiral direction of the spiral plate is left-handed, and the rotation direction of the shaft is clockwise.

[0008] Furthermore, the distance between the left and right ends of the spiral plate corresponds to the distance from the left inner surface of the filter cylinder to the right end opening; the spiral plate is evenly distributed with through holes along the spiral direction of the spiral plate.

[0009] Furthermore, the angle between the shell and the horizontal plane is α, and the range of the angle α is 5°-15°.

[0010] The beneficial effects of this utility model through the above technical solution are as follows: In this invention, during the filtration process, the motor is not operating, and the composite carbon source liquid enters the filter cylinder and the housing. Impurity particles are trapped inside the filter cylinder, and the purified composite carbon source liquid is discharged through the drain pipe. During slag discharge, the composite carbon source liquid inside the housing is emptied, the motor drives the spiral plate to rotate, and the spiral plate drives the impurity particles to be discharged through the slag outlet. This invention can easily clean the impurity particles inside the filter cylinder, preventing a large amount of filter residue from remaining inside the filter cylinder, which is beneficial for subsequent filtration processes.

[0013] The present invention will be further described below with reference to the accompanying drawings and specific embodiments: like Figures 1-3As shown, a slag removal and purification device for composite carbon source production includes a shell 1, which is a cylindrical body with openings at both ends sealed by sealing plates. The lower left and right ends of the shell 1 are supported by support plates 2, with the lower ends of the two support plates being flush. The device also includes a filter cylinder 3 and a spiral plate 4. The shell 1 is positioned with the left side higher than the right. The filter cylinder 3 is a cylindrical body with one end open and the other end closed. The filter cylinder 3 is coaxial with the shell 1. The open end of the filter cylinder 3 is located inside the shell 1 and connected to the closed end on the right side of the shell 1. The closed end of the filter cylinder 3 penetrates the closed end on the left side of the shell 1 and is located inside the shell 1. The filter cylinder 3 has filter holes 5 evenly distributed on the lower part of its peripheral wall. The filter cylinder 3 outside the shell 1 has a slag outlet hole 6 on the lower part of its peripheral wall. The slag outlet hole 6 is a rectangular hole. The upper left end of the shell 1 is fixed with a liquid outlet pipe 7 that connects to the filter cylinder 3. The lower right closed end of the shell 1 is fixed with a drain pipe 8. One end of the drain pipe 8 is connected to the shell 1 and is located between the filter cylinder 3 and the peripheral wall of the shell 1. The filter cylinder 3 has a rotating shaft 9 that rotates coaxially. The rotating shaft 9 is a round rod. The shell 1 has a motor 10 for driving the rotating shaft 9 to rotate. The rotating shaft 9 is fitted with a spiral plate 4.

[0014] There is a gap between the outer wall of the filter cylinder 3 and the inner wall of the housing 1. The left closed end of the housing 1 is provided with a connecting hole 11 for the filter cylinder 3 to pass through. The outer wall of the filter cylinder 3 is fixedly connected to the connecting hole 11.

[0015] The left end of the rotating shaft 9 is rotatably connected to the closed end of the filter cylinder 3 via a sealed bearing 12, and the right end of the rotating shaft 9 is rotatably connected to the right closed end of the housing 1 via a sealed bearing 13. A motor 10 is fixed on the outer right side of the housing 1, and the output end of the motor 10 is connected to the right end of the rotating shaft 9. The motor model selected in this utility model is Y2-200L1-2Y.

[0016] The outer edge of the spiral plate 4 slides in contact with the inner wall of the filter cylinder 3. The spiral direction of the spiral plate 4 is left-handed, and the rotation direction of the rotating shaft 9 is clockwise (the clockwise rotation of the rotating shaft 9 is...). Figure 2 (Right-view perspective).

[0017] The distance between the left and right ends of the spiral plate 4 corresponds to the distance from the inner left side of the filter cylinder 3 to the opening at the right end; through holes 14 are evenly distributed along the spiral direction of the spiral plate 4, and the through holes 14 are circular holes to facilitate the flow of composite carbon source liquid.

[0018] The angle between the shell 1 and the horizontal plane is α, and the range of the angle α is 5°-15°. The purpose is to ensure the speed of the liquid flowing to the right, avoid the angle being too small, which would result in a slow flow rate and cause the filter residue to stagnate, and avoid the angle being too large, which would make it difficult to ensure that the filter residue is stably pushed by gravity when the spiral plate 4 pushes it.

[0019] When in use, the motor 10 does not work at first. The composite carbon source solution to be filtered is injected into the filter cylinder 3 through the liquid inlet pipe 7. The composite carbon source solution flows to the right in the housing 1 and the filter cylinder 3. Impurity particles in the composite carbon source liquid are intercepted by the filter holes 5 on the filter cylinder 3. The liquid after impurity removal is discharged through the liquid outlet pipe 8. When it is necessary to clean the impurity particles in the filter cartridge 3, stop feeding liquid into the housing 1. After the composite carbon source liquid in the housing 1 has been completely discharged, the motor 10 drives the rotating shaft 9 to rotate clockwise (the clockwise rotation of the rotating shaft 9 is...). Figure 2 (From the right-hand view), the left-hand spiral plate 4 rotates clockwise with the rotating shaft 9. The clockwise rotating spiral plate 4 pushes the impurity particles in the filter cylinder 3 to the left. After the impurity shell 1 is pushed into the filter cylinder 3 outside the shell 1, the impurity particles are discharged through the slag outlet 6. A slag receiving device can be set under the slag outlet 6. After the slag discharge hole 6 stops discharging filter residue, most of the filter residue in the filter cylinder 3 is discharged (there may be a small amount of filter residue adhering to the spiral plate 4, but it will no longer affect the subsequent filter residue work). The operation of the motor 10 is stopped, and the subsequent purification work of the composite carbon source liquid can be carried out.

[0020] The preferred embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Any equivalent or equivalent modifications or substitutions to the technical solutions of the present utility model without departing from the spirit of the present utility model or the scope of disclosure shall fall within the protection scope of the present utility model.
