Description

Technical Field

[0001] This utility model belongs to the field of slag treatment technology, specifically relating to a continuous slag washing mechanism. Background Technology

[0002] During the incineration of combustibles (such as coal and household waste), slag is produced. Since the slag contains a certain amount of heavy metals, it is usually sorted by washing with water.

[0003] According to the authorized announcement number CN220072624U, a device for circulating water washing treatment of municipal solid waste incinerator slag is known prior art. Although this patent has the advantage of circulating and filtering the water inside the slag washing tank, the technical solution of this patent still has the following defects in actual use: In this patent, the slag is transported to the inside of the slag washing tank through the slag conveying component, but it is not convenient to remove the washed slag from the inside of the slag washing tank. It is still necessary to manually remove the washed slag from the inside of the slag washing tank, which is labor-intensive, has low slag washing efficiency, and is not conducive to continuous slag washing treatment. Utility Model Content

[0004] The purpose of this invention is to provide a continuous slag washing mechanism to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a continuous slag washing mechanism, including a frame, a washing tank is provided above the frame, the washing tank is used for washing the slag, and a filter water tank is provided on one side of the top of the frame in close contact with the washing tank. Two symmetrically distributed elevators are provided on the other side of the top of the frame. A circulating conveyor is provided below the frame, with one end located directly below the washing tank. A diversion component is provided at one end of the frame on the ground. The diversion component is used to transfer the slag conveyed by the circulating conveyor to the inside of the elevator for conveying.

[0006] In a preferred embodiment, the frame is welded from square steel, and several support rods are provided below the frame.

[0007] In a preferred embodiment, the top of the washing tank is fixedly provided with a flared opening; Ear plates are fixedly installed on both outer walls of the washing tank; The bottom of the washing tank is provided with discharge ports on both sides, and a sealing plate is slidably inserted into the discharge port; A drain mesh cover is fixedly installed at the bottom center of the washing tank, and mesh plates are provided on both sides of the top of the drain mesh cover.

[0008] In a preferred embodiment, a water inlet pipe is provided at the bottom of the filter tank, and a water outlet pipe is provided at the top of the filter tank.

[0009] In a preferred embodiment, a material box is provided at the lower end of the elevator, and a column is fixedly installed on the outer wall of the bottom of the material box, while an elbow is provided at the upper end of the elevator.

[0010] In a preferred embodiment, the circulating conveyor is composed of a horizontal section located below the frame and an inclined section located at the end of the frame, with support legs provided on the outer sides of both the horizontal and inclined sections.

[0011] In a preferred embodiment, the diversion assembly includes a guide frame fixed to the top of the hopper, with an end plate fixedly installed at one end of the guide frame. An arch slope is slidably provided above the guide frame, with a lower baffle fixedly installed on one outer wall of the arch slope and a baffle plate fixedly installed on the other outer wall of the arch slope.

[0012] Compared with the prior art, the beneficial effects of this utility model are: This continuous slag washing mechanism, through the set elevator, can lift and transport the slag to the top of the washing tank, where the slag is washed inside the washing tank.

[0015] The present invention will be further described below with reference to the embodiments.

[0016] The following embodiments are used to illustrate the present invention, but should not be used to limit the scope of protection of the present invention. The conditions in the embodiments can be further adjusted according to specific conditions, and simple improvements to the method of the present invention under the concept of the present invention are all within the scope of protection claimed by the present invention.

[0017] Please see Figure 1 and Figure 2 This utility model provides a continuous slag washing mechanism, including a frame 1, which is welded from square steel, and several support rods are provided below the frame 1.

[0018] In this embodiment, the frame 1 serves as the basic support structure of the mechanism.

[0019] Please see Figure 3 and Figure 4 A washing tank 2 is installed above the frame 1. The washing tank 2 is used to wash the slag. A flared opening 21 is fixedly installed on the top of the washing tank 2. Ear plates 22 are fixedly installed on both outer walls of the washing tank 2. A discharge port is provided on both sides of the bottom of the washing tank 2, and a sealing plate 23 is slidably inserted into the discharge port. A drain screen 24 is fixedly installed in the middle of the bottom of the washing tank 2. A mesh plate 25 is provided on both sides of the top of the drain screen 24.

[0020] In this embodiment, the bottom of the washing tank 2 is sealed by the sealing plate 23, which can ensure the integrity of the internal space of the washing tank 2 and realize the washing effect of slag. At the same time, a stirring mechanism (not shown) can also be inserted at the top of the washing tank 2, thereby improving the washing effect of slag. The draining mesh cover 24 and mesh plate 25 used can drain the water inside the washing tank 2 and retain the slag. The mesh plates 25 on both sides are inclined to avoid the slag from blocking the draining mesh cover 24.

[0021] Please see Figure 1A filter water tank 3 is installed on one side of the top of the frame 1, which is close to the washing tank 2. The filter water tank 3 is used to draw water from the washing tank 2 for circulating filtration. A water inlet pipe 31 is installed below the filter water tank 3, and a water outlet pipe 32 is installed on the top of the filter water tank 3.

[0022] In this embodiment, the filter tank 3 is also a commonly used structure in the prior art, which can filter and purify the water inside the washing tank 2, making it clean. The volume of the filter tank 3 is larger than that of the washing tank 2, so as to ensure that the water inside the washing tank 2 completely enters the filter tank 3. The filtered water is pumped back into the washing tank 2 using the water pumping pipe 32, and the water supply pipe 31 can completely pump the water inside the washing tank 2 into the filter tank 3 for processing and temporary storage.

[0023] Please see Figure 1 and Figure 2 Two symmetrically distributed elevators 4 are provided on the other side of the top of the frame 1. A material box 41 is provided at the lower end of the elevator 4. A column 42 is fixedly installed on the outer wall of the bottom of the material box 41. An elbow 43 is provided at the upper end of the elevator 4. The elbow 43 is designed to prevent slag from splashing when it enters the washing tank 2.

[0024] In this embodiment, the internal structure of the elevator 4 is the existing spiral conveying method (not shown in the figure), which can achieve the lifting effect of conveying slag, transporting the slag located at a low position to the top of the water washing tank 2 at a high position, and entering the interior of the water washing tank 2 for water washing.

[0025] Please see Figure 1 and Figure 2 Below the frame 1, there is a circulating conveyor 5 with one end located directly below the washing tank 2. The circulating conveyor 5 is composed of a horizontal part 51 located below the frame 1 and an inclined part 53 located at the end of the frame 1. Support legs 52 are provided on the outer side of both the horizontal part 51 and the inclined part 53. The support legs 52 enable the circulating conveyor 5 to be stably placed on the ground. As for the specific structure of the circulating conveyor 5, it is an existing conveyor belt conveying structure, which is also a commonly used material conveying structure in the prior art, and will not be described in detail.

[0026] In this embodiment, after the slag inside the washing tank 2 is discharged, it falls onto the horizontal part 51 for conveying, and the height of the slag is raised by the inclined part 53, so that the slag can enter the diversion component 6 and the inside of the material box 41 in a better way.

[0027] Please see Figure 1 and Figure 5One end of the frame 1 is provided with a diversion component 6 located on the ground. The diversion component 6 is used to transfer the slag conveyed by the circulating conveyor 5 to the internal conveying of the elevator 4. The diversion component 6 includes a guide frame 61 fixed to the top of the material box 41, and an end plate 62 is fixedly installed at one end of the guide frame 61. The end plate 62 is used to limit the sliding of the arch slope 64. The arch slope 64 is slidably arranged above the guide frame 61. A lower baffle 63 is fixedly installed on one side of the outer wall of the arch slope 64, which also serves to block the slag. A baffle plate 65 is fixedly installed on the other side of the outer wall of the arch slope 64 to block the material on the upper side of the arch slope 64 and prevent the slag from splashing.

[0028] In this embodiment, the arch slope 64 can be set to 45°. After the slag is conveyed to the top of the arch slope 64 by the circulating conveyor 5, it is diverted by the slopes on both sides, so that the slag can enter the interior of the hopper 41. The arch slope 64 can slide on the guide frame 61, thereby changing the position of the arch slope 64 and realizing two paths of slag conveying: entering the hopper 41 and not entering the hopper 41.

[0029] The working principle and usage process of this utility model are as follows: First, the operator puts the slag into the inside of the material box 41. The working of the elevator 4 can transport the slag to the top of the washing box 2 and allow the slag to enter the inside of the washing box 2. The washing operation of the slag is carried out inside the washing box 2. After the slag has been washed for a period of time, the water pump inside the filter tank 3 is started to draw the water inside the washing tank 2 from the bottom and process it inside the filter tank 3. Finally, the filtered clean water is added back from the top of the washing tank 2. After the water inside the washing tank 2 is completely drained, the operator opens the sealing plate 23 and can transfer the slag to the circulating conveyor 5. The circulating conveyor 5 is started to transport the slag after one wash to the diversion component 6. The diversion component 6 is used to transport the slag to both sides, so that the slag falls into the inside of the material box 41, and finally the slag enters the washing tank 2 again for multiple washes. After the final slag wash, the operator slides the arch slope 64 on the guide frame 61 to prevent the slag conveyed by the circulating conveyor 5 from entering the hopper 41. The operator can then use other containers or trolleys to collect the washed slag.

[0030] In the above scheme, it should be noted that: the elevator 4 is an existing spiral conveyor structure with built-in auger, and the circulating conveyor 5 is an existing conveyor belt conveyor structure. Since both the elevator 4 and the circulating conveyor 5 are mature products of existing technology, and the specific structure, electrical connection method, installation method and working principle of the elevator 4 and the circulating conveyor 5 are all existing publicly available technologies, they will not be described in detail here.

[0031] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles of the present invention, the scope of which is defined by the appended claims and their equivalents.
