Shaftless drum type slag cleaning device

Abstract

This utility model proposes a shaftless drum-type slag cleaning device, relating to the field of slag treatment technology. It includes a base plate, on the upper surface of which a cleaning water tank is fixed. A fine screen cylinder is installed inside the cleaning water tank. This shaftless drum-type slag cleaning device, when started, drives a rotating rod to rotate. Through a transmission belt and transmission pulley, the fine and coarse screen cylinders rotate simultaneously, performing slag cleaning and screening operations at the same time. Larger slag particles screened by the coarse screen cylinder fall into the second discharge chute, while smaller slag particles screened by the fine screen cylinder fall into the first discharge chute. Ash, after being washed and mixed with water, falls into the cleaning water tank and is discharged through a water outlet pipe. This allows for step-by-step slag screening, improving the efficiency of subsequent slag utilization. Furthermore, a cleaning rod can be used to clean the outer surface of the fine screen cylinder, preventing long-term contact between the outer surface of the fine screen cylinder and the wastewater inside the cleaning water tank, thus preventing clogging of the fine filter pores.

Description

Technical Field

[0001] This utility model relates to a slag cleaning device, specifically a shaftless drum-type slag cleaning device, belonging to the field of slag treatment technology. Background Technology

[0002] Household waste is often reduced in size and its internal toxic and harmful substances are eliminated through incineration. Household waste that has been incinerated at high temperatures often leaves behind a lot of solid waste. After processing, this solid waste can be used to make floor tiles and other products. However, the solid waste after high-temperature incineration contains solids of different particle sizes, and the slag needs to be cleaned before use.

[0003] Chinese patent application publication number CN217314501U discloses a fully automatic drum screen cleaning device for slag. This utility model reduces the manual labor required for turning the drum screen. The cleaning mechanism uses a cleaning brush that moves back and forth to clean the drum, eliminating the need for manual brushing. This saves time and effort, and provides a more uniform and effective cleaning result.

[0004] Although the above-mentioned patented solution can clean the drum screen, the cleaning device in the above-mentioned patent is not convenient for separating the slag during use. After the slag is cleaned, it still piles up together after being poured out. The use of incineration slag of different particle sizes as a mixed body will make it difficult to meet the corresponding requirements.

[0005] Therefore, a shaftless drum-type slag cleaning device is proposed here. Utility Model Content

[0006] This utility model proposes a shaftless drum-type slag cleaning device, which uses a fine screen cylinder and a coarse screen cylinder to screen the slag step by step, thereby improving the efficiency of subsequent slag utilization. At the same time, a cleaning rod can be used to clean the outer surface of the fine screen cylinder to avoid clogging the fine filter holes.

[0007] This utility model is achieved through the following technical solution: a shaftless drum-type slag cleaning device, including a base plate, a cleaning water tank fixed on the upper surface of the base plate, a fine screen cylinder inside the cleaning water tank, a coarse screen cylinder inside the fine screen cylinder, a set of connecting rods evenly fixed between the fine screen cylinder and the coarse screen cylinder, two sets of transmission components for driving the fine screen cylinder to rotate inside the cleaning water tank, the transmission components including a set of limiting blocks fixed to the inner side wall of the cleaning water tank, a rotating rod rotatably sleeved inside the limiting blocks, a transmission belt drivingly connecting multiple rotating rods, and a second transmission collar sleeved on the outer surface of the second transmission collar drivingly connecting the surface of the transmission belt.

[0008] Furthermore, a transmission sleeve is fixedly sleeved around the outer periphery of the rotating rod, and a first transmission collar is fixedly sleeved on the outer surface of the transmission sleeve.

[0009] Furthermore, a motor is fixed to one side of the cleaning pool, and the output end of the motor is fixed to one end of the rotating rod located above.

[0010] Furthermore, a set of fine filter holes are uniformly formed on the surface of the fine sieve cylinder, and a set of coarse filter holes are uniformly formed on the surface of the coarse sieve cylinder, with the inner diameter of the coarse filter holes being larger than the inner diameter of the fine filter holes.

[0011] Furthermore, two support plates are fixed to the inner wall of the cleaning pool. A set of rollers supporting the fine screen cylinder is installed on the side of the support plate near the fine screen cylinder, and the rollers are installed at a position slightly below the center of the fine screen cylinder.

[0012] Furthermore, a first discharge chute and a second discharge chute are respectively installed on both sides of the cleaning pool, and the first discharge chute and the second discharge chute are fixed to the upper surface of the base plate. A column is fixed to the side of the base plate near the first discharge chute, and a feeding rack is fixed to the top surface of the column.

[0013] A water outlet pipe is installed on one side of the cleaning pool. A cleaning assembly is installed above the cleaning pool to clean the surfaces of the fine sieve cylinder and the coarse sieve cylinder respectively. The cleaning assembly includes a cleaning rod installed above the cleaning pool, and the cleaning rod is in contact with the surface of the fine sieve cylinder. A support block is fixed between the cleaning rod and the support plate.

[0014] Furthermore, a connecting water pipe is fixed to the upper surface of the cleaning water tank, and a set of water spraying rings are installed on one side of the connecting water pipes, with the water spraying rings located outside the fine screen cylinder.

[0015] This utility model provides a shaftless drum-type slag cleaning device, which has the following beneficial effects:

[0016] 1. This shaftless drum-type slag cleaning device starts with a motor that drives the rotating rod to rotate. Through the transmission belt and transmission pulley, the fine screen cylinder and the coarse screen cylinder can rotate simultaneously, performing screening operations while cleaning the slag. Larger slag particles screened by the coarse screen cylinder fall into the second discharge chute, while smaller slag particles screened by the fine screen cylinder fall into the first discharge chute. The ash is washed, mixed with water, and falls into the cleaning water tank, and is discharged through the water outlet pipe. This device can perform step-by-step screening of slag, improving the efficiency of subsequent slag utilization.

[0017] 2. This shaftless drum-type slag cleaning device can clean the outer surface of the fine screen cylinder by using a cleaning rod when the fine screen cylinder and the coarse screen cylinder are rotating, so as to prevent the outer surface of the fine screen cylinder from being in long-term contact with the sewage inside the cleaning pool and clogging the fine filter pores.

[0028] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of this application.

[0029] Please see Figures 1-4The present invention proposes the following implementation scheme: a shaftless drum-type slag cleaning device, including a base plate 1, a cleaning water tank 2 fixed on the upper surface of the base plate 1, a fine screen cylinder 3 inside the cleaning water tank 2, a coarse screen cylinder 4 inside the fine screen cylinder 3, a set of connecting rods 32 evenly fixed between the fine screen cylinder 3 and the coarse screen cylinder 4, and two sets of transmission components 5 for driving the fine screen cylinder 3 to rotate inside the cleaning water tank 2. The transmission components 5 include a set of limiting blocks 51 fixed on the inner side wall of the cleaning water tank 2, a rotating rod 52 rotatably sleeved inside the limiting block 51, a transmission belt 53 drivingly connecting multiple rotating rods 52, and a second transmission collar 57 sleeved on the outer surface of the second transmission collar 57 drivingly connecting the surface of the transmission belt 53.

[0030] Please refer to this carefully. Figure 2 and Figure 3 A transmission sleeve 54 is fixedly sleeved around the outer periphery of the rotating rod 52, and a first transmission sleeve 56 is fixedly sleeved on the outer surface of the transmission sleeve 54.

[0031] A motor 55 is fixed to one side of the cleaning pool 2, and the output end of the motor 55 is fixed to one end of the rotating rod 52 located above.

[0032] In the above scheme, the motor 55 drives the rotating rod 52 to rotate, and the transmission belt 53 can drive multiple rotating rods 52 to rotate at the same time. The friction between the transmission belt 53 and the second transmission sleeve 57 drives the fine screen cylinder 3 to rotate.

[0033] Please refer to this carefully. Figure 3 The surface of the fine sieve cylinder 3 is uniformly provided with a set of fine filter holes 31, and the surface of the coarse sieve cylinder 4 is uniformly provided with a set of coarse filter holes 41, and the inner diameter of the coarse filter holes 41 is larger than the inner diameter of the fine filter holes 31.

[0034] Please refer to this carefully. Figure 4 Two support plates 21 are fixed to the inner wall of the cleaning pool 2. A set of rollers 22 supporting the fine screen cylinder 3 are installed on the side of the support plate 21 near the fine screen cylinder 3, and the rollers 22 are installed at a position slightly below the center of the fine screen cylinder 3.

[0035] Please refer to this carefully. Figure 1 The first discharge trough 33 and the second discharge trough 42 are respectively installed on both sides of the cleaning pool 2, and the first discharge trough 33 and the second discharge trough 42 are fixed on the upper surface of the base plate 1. A column 6 is fixed on the side of the base plate 1 near the first discharge trough 33, and a feeding rack 7 is fixed on the top surface of the column 6.

[0036] In the above scheme, the larger slag particles screened by the coarse screen cylinder 4 fall into the second discharge chute 42, and the smaller slag particles screened by the fine screen cylinder 3 fall into the first discharge chute 33.

[0037] Please refer to this carefully. Figure 1 and Figure 4 A water outlet pipe 23 is installed on one side of the cleaning pool 2. A cleaning component 9 is installed above the cleaning pool 2 to clean the surfaces of the fine screen cylinder 3 and the coarse screen cylinder 4 respectively. The cleaning component 9 includes a cleaning rod 91 installed above the cleaning pool 2, and the cleaning rod 91 is in contact with the surface of the fine screen cylinder 3. A support block 92 is fixed between the cleaning rod 91 and the support plate 21.

[0038] In the above scheme, when the fine screen cylinder 3 and the coarse screen cylinder 4 rotate, the outer surface of the fine screen cylinder 3 can be cleaned by the cleaning rod 91.

[0039] Please refer to this carefully. Figure 1 A connecting water pipe 8 is fixed on the upper surface of the cleaning water tank 2. A set of water spraying rings 81 are installed on one side of the connecting water pipe 8, and the water spraying rings 81 are set outside the fine screen cylinder 3.

[0040] In the above scheme, the water pipe 8 is connected to an external water source and the slag is cleaned through the water spray ring 81.

[0041] In use, the slag is poured into the coarse screen cylinder 4 through the feed rack 7. The motor 55 is started to drive the rotating rod 52 to rotate. The transmission belt 53 can drive multiple rotating rods 52 to rotate simultaneously. The friction between the transmission belt 53 and the second transmission sleeve 57 drives the fine screen cylinder 3 to rotate between the two sets of support plates 21. The cooperation between the transmission wheel 54 and the first transmission sleeve 56 also drives the fine screen cylinder 3 to rotate simultaneously. This allows the fine screen cylinder 3 and the coarse screen cylinder 4 to rotate simultaneously, performing screening operations while cleaning the slag. The slag passes through the coarse screen cylinder. Larger slag particles are screened out and fall into the second discharge trough 42. Smaller slag particles are screened out by the fine screen cylinder 3 and fall into the first discharge trough 33. The ash is washed and mixed with water and falls into the cleaning water tank 2, and is discharged through the water outlet pipe 23. This process can screen the slag step by step and improve the efficiency of subsequent slag use. When the fine screen cylinder 3 and the coarse screen cylinder 4 rotate, the cleaning rod 91 can be used to clean the outer surface of the fine screen cylinder 3, so as to prevent the outer surface of the fine screen cylinder 3 from being in long-term contact with the sewage inside the cleaning water tank 2 and the stains from clogging the fine filter holes 31.
