Abstract
Description
Technical Field
[0001] This utility model relates to the field of slag washing technology, specifically to a waste incineration slag washing treatment device. Background Technology
[0002] The slag from municipal solid waste incineration power plants is mainly a heterogeneous mixture composed of stones, sand, glass, ceramics, ash, and a small amount of unburned waste. After crushing and sorting, the slag has stable chemical properties, good durability, and high strength. Slag is a non-toxic general waste that can be directly landfilled or processed for utilization. After technical processing, the slag is suitable for making non-fired bricks or other building materials and has a certain recycling value.
[0003] Waste incineration slag washing is an important pretreatment process aimed at removing impurities, soluble salts, and harmful substances from the slag, thereby improving its utilization value and reducing its environmental impact. Traditional washing devices typically employ fixed screens and simple spray systems, resulting in low screening accuracy and difficulty in effectively separating fine particles and impurities from the slag. Furthermore, the large number of fine particles and impurities in the slag easily adheres to the screens and filter holes during washing, causing blockages. Traditional washing devices lack effective anti-clogging and cleaning functions; once the screens or filter holes become clogged, manual cleaning is required, a cumbersome and inefficient process. Utility Model Content
[0004] The purpose of this invention is to provide a waste incineration slag washing treatment device to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a waste incineration slag washing treatment device, comprising:
[0006] The outer cover has a water collection tank inside;

[0011] Preferably, the filter cylinder is nested inside the water collection tank, and the feed cylinder and discharge cylinder rotate through the left and right side walls of the water collection tank respectively, which enhances the structural stability of the conveying and filtering assembly. The two ends of the spiral blades extend into the feed cylinder and discharge cylinder respectively, realizing the continuous conveying and processing of slag.
[0012] Preferably, the feed head has a feed channel to ensure that the slag enters the conveying and filtering assembly smoothly;
[0013] A limiting plate is connected between the outer wall of the feed head and the left side wall of the outer cover, which restricts the position of the feed head, enhances the stability of the feed head, and prevents the feed head from rotating with the feed cylinder.
[0014] Preferably, a second support plate is fixed to the right end of the feeding channel, and a first support plate is fixed to the right side of the outer cover;
[0015] The left end of the water spray pipe is connected to the second support plate, and the end of the water spray pipe away from the second support plate passes through the first support plate and is connected to a water supply pipe.
[0016] The nozzle is nested inside the water filter cylinder;

[0018] Preferably, the air blowing assembly includes an arc-shaped hollow plate, with multiple nozzles evenly spaced at the bottom of the arc-shaped hollow plate. An air supply pipe is connected to the upper side of the arc-shaped hollow plate and is connected to an air source. The air source blows air into the arc-shaped hollow plate through the air supply pipe, and the air is ejected from the nozzles to blow air onto the top of the water filter cylinder, cleaning the mesh at the top of the water filter cylinder and preventing clogging.
[0019] Preferably, each of the four upper corners of the arc-shaped hollow plate is fixed with a connecting support, which is connected to the outer cover. The four connecting supports ensure that the arc-shaped hollow plate is firmly fixed to the outer cover, thereby enhancing the stability of the air blowing assembly.
[0020] Preferably, the bottom of the outer cover is fixed with a support leg, and the bottom of the outer cover is provided with multiple sewage pipes, each equipped with a sewage valve. The multiple sewage pipes enable timely discharge of sewage from the collection tank.

[0022] The drive motor drives the transmission gear to rotate, and the transmission gear meshes with the external gear ring to drive the feed cylinder to rotate, thereby driving the filter cylinder and the discharge cylinder to rotate synchronously.
[0023] The technical effects and advantages provided by this utility model in the above technical solution are as follows:
[0024] 1. The conveying and filtration assembly, through the combination of a feed cylinder, a filter cylinder, and a discharge cylinder with spiral blades, achieves continuous conveying and processing of slag, and the slag is in a state of constant tumbling. The water spray pipe is nested inside the spiral blades but does not contact the spiral blades. Multiple nozzles are installed at equal intervals on its lower side wall, which can uniformly spray water to wash the slag in the filter cylinder. The conveying and filtration assembly, together with the water spray pipe, improves the washing effect, effectively removes impurities and harmful substances from the surface of the slag, and improves the cleanliness of the slag.
[0025] 2. By using the air blowing component, when the filter cylinder rotates, the air blowing component sprays air through the nozzles. The airflow, with its impact force and continuous action, can effectively clean the particles and impurities on the mesh at the top of the filter cylinder, preventing the mesh from clogging. During the slag treatment process, the continuous action of the airflow can clean the mesh in a timely manner, ensuring that the mesh of the filter cylinder always maintains good water permeability. This ensures that the wastewater generated during cleaning can be smoothly discharged through the mesh, thereby improving the filtration efficiency. Attached Figure Description

[0038] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.
[0039] This utility model provides, for example Figures 1 to 4 The waste incinerator slag washing treatment device shown includes:
[0040] Outer cover 10, with a water collection tank 11 inside the outer cover 10;
[0041] The water conveying and filtration assembly 20 is rotatably nested inside the outer cover 10. The water conveying and filtration assembly 20 includes a feed cylinder 21, a filter cylinder 22 and a discharge cylinder 23 connected in sequence. A spiral blade 24 is fixed inside the filter cylinder 22. A feed head 25 is rotatably connected to the end of the feed cylinder 21 away from the filter cylinder 22. An external toothed ring 26 is fixedly sleeved on the outside of the feed cylinder 21.
[0042] The water spray pipe 30 is nested inside the spiral blade 24 and does not contact the spiral blade 24. Multiple nozzles 31 are installed at equal intervals on the lower side wall of the water spray pipe 30.
[0043] Drive assembly 50 is engaged with external gear ring 26.
[0044] The filter cylinder 22 is nested inside the water collection tank 11. The feed cylinder 21 and discharge cylinder 23 rotate through the left and right side walls of the water collection tank 11, respectively, which enhances the structural stability of the conveying and filtering assembly 20. The two ends of the spiral blade 24 extend into the feed cylinder 21 and discharge cylinder 23, respectively, realizing the continuous conveying and processing of slag.
[0045] The feed head 25 has a feed channel 251 inside, which can ensure that the slag enters the conveying and filtering assembly 20 smoothly;
[0046] A limiting plate 12 is connected between the outer wall of the feed head 25 and the left side wall of the outer cover 10, which restricts the position of the feed head 25, enhances the stability of the feed head 25, and prevents the feed head 25 from rotating with the feed cylinder 21.
[0047] A second support plate 252 is fixed at the right end of the feed channel 251, and a first support plate 13 is fixed at the right side of the outer cover 10.
[0048] The left end of the water spray pipe 30 is connected to the second support plate 252, and the end of the water spray pipe 30 away from the second support plate 252 passes through the first support plate 13 and is connected to the water supply pipe 32.
[0049] The nozzle 31 is nested inside the filter cylinder 22;
[0050] The end of the water supply pipe 32 away from the water spray pipe 30 is connected to the water source. Water from the water source enters the water spray pipe 30 through the water supply pipe 32 and is then sprayed out through the nozzle 31 to spray water to wash the slag in the filter cylinder 22, thereby improving the washing effect.
[0051] The bottom of the outer cover 10 is fixed with a support leg 14, and the bottom of the outer cover 10 is provided with multiple sewage pipes 15. Sewage valves are installed on the sewage pipes 15. The multiple sewage pipes 15 can discharge the sewage in the water collection tank 11 in a timely manner.
[0052] The external gear ring 26 is located to the left of the outer cover 10. The drive assembly 50 includes a drive motor 51. The output end of the drive motor 51 is connected to a transmission gear 52. The transmission gear 52 is located on the lower side of the external gear ring 26 and meshes with the external gear ring 26.
[0053] In this invention, the drive motor 51 drives the transmission gear 52 to rotate. The transmission gear 52 meshes with the external gear ring 26, driving the feed cylinder 21 to rotate. This, in turn, drives the water filter cylinder 22, the discharge cylinder 23, and the spiral blades 24 to rotate synchronously. The slag to be washed is added into the feed cylinder 21 through the feed channel 251. The rotating spiral blades 24 transport the slag, allowing it to pass through the feed cylinder 21, the water filter cylinder 22, and the discharge cylinder 23 in sequence. Simultaneously, water from the water source enters the spray pipe 30 through the water supply pipe 32 and is then sprayed out through the nozzle 31 to rinse the slag in the water filter cylinder 22. Because the water filter cylinder 22 and the spiral blades 24 rotate synchronously, the slag is constantly agitated. The water sprayed from the nozzle 31 can effectively rinse the constantly agitated slag, improving the rinsing effect, effectively removing impurities and harmful substances from the slag surface, and enhancing the cleanliness of the slag.
[0054] like Figure 1 and Figure 5 As shown, the air blowing assembly 40 is located above the water filter cylinder 22;
[0055] The air blowing assembly 40 includes an arc-shaped hollow plate 41. Multiple nozzles 42 are installed at equal intervals on the bottom of the arc-shaped hollow plate 41. An air supply pipe 43 is connected to the upper side of the arc-shaped hollow plate 41. The air supply pipe 43 is connected to an air source. The air source blows air into the arc-shaped hollow plate 41 through the air supply pipe 43. The air is sprayed out from the nozzles 42 to blow air onto the top of the water filter cylinder 22, cleaning the mesh at the top of the water filter cylinder 22 and preventing clogging.
[0056] The upper four corners of the arc-shaped hollow plate 41 are all fixed with connecting supports 44, which are connected to the outer cover 10. The setting of the four connecting supports 44 makes the arc-shaped hollow plate 41 firmly fixed on the outer cover 10, thereby enhancing the stability of the air blowing assembly 40.
[0057] In this invention, the air blowing assembly 40 includes an arc-shaped hollow plate 41 with multiple nozzles 42 evenly spaced at its bottom. An air supply pipe 43 is connected to the upper side of the arc-shaped hollow plate 41 and is connected to an air source. The air source blows air into the arc-shaped hollow plate 41 through the air supply pipe 43, and the air is ejected from the nozzles 42, forming a strong airflow. The airflow direction of the nozzles 42 is directed towards the mesh area at the top of the filter cylinder 22. During the operation of the filter cylinder 22, fine particles and impurities in the slag may adhere to the mesh, causing the mesh to become clogged. The air blowing assembly 40 ejects airflow from the nozzles 42 to the top of the filter cylinder 22. The airflow ejected from the nozzles 42 has a certain pressure and speed, which can strongly impact the mesh at the top of the filter cylinder 22. This impact force can effectively loosen and blow away particles and impurities attached to the mesh, preventing them from accumulating and clogging. This ensures that the mesh of the filter cylinder 22 can always maintain good water permeability, ensuring that wastewater can be discharged smoothly through the mesh during the washing process, thereby improving the filtration efficiency. At the same time, it works in conjunction with other components to further enhance the performance and reliability of the entire waste incinerator slag washing treatment device.
[0058] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
