Description

Technical Field

[0001] This utility model relates to the technical field of drying kiln cleaning devices, specifically a drying kiln anti-material accumulation cleaning device. Background Technology

[0002] A drying kiln is a large-scale drying equipment used in industrial production. Its main body is a clockwise rotating cylinder slightly inclined to the horizontal. Material is fed in from the higher end, comes into contact with hot air, and as the cylinder rotates clockwise, the material flows to the lower end under gravity and is dried and discharged. Based on the direction of the drying medium and the material flow, it is divided into two types: co-current and counter-current. In a co-current kiln, the combustion chamber and the wet material feed are at the same end, and the hot airflow is in the same direction as the material movement. In a counter-current kiln, the wet material is fed in from the feed end, the combustion chamber is at the discharge end, and the material and the drying medium move in opposite directions.

[0003] Zinc smelting waste slag contains about 35% water. When it is disposed of in a harmless manner, the high moisture content will lead to problems such as increased energy consumption of the melting furnace, reduced processing efficiency, and a large amount of acid produced from flue gas, which will affect the overall operation of the system. Therefore, before entering the melting furnace, the waste slag needs to be pre-dried to about 15% water content in a drying kiln to meet the process operation requirements. Traditional natural gas drying kilns are designed with lifting plates inside, which makes the movement trajectory of the material in the kiln more complex, increases the contact area between the material and the hot air, and thus improves the heat exchange efficiency.

[0004] However, because the waste residue contains a large amount of complex components such as iron, calcium, and silicon, the inner wall of the kiln is prone to caking during the drying process, covering the lifting plate and continuously reducing the effective space inside the kiln. This leads to a series of problems such as a continuous decrease in output, increased energy consumption, poor heat exchange, and inability to retain moisture in the dried residue. Ultimately, the kiln cannot operate normally. In actual production, it can no longer meet the process requirements after about a week of operation, and the kiln needs to be shut down for maintenance. This increases the labor intensity and seriously affects the production efficiency. Therefore, a drying kiln anti-accumulation cleaning device is proposed to solve the problems mentioned above. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a drying kiln anti-accumulation cleaning device, which solves the problem that in existing drying kilns, slag clumps onto the inner wall of the kiln during operation, covering the lifting plate, causing the effective space inside the kiln to continuously shrink, heat exchange to deteriorate, and failing to meet process requirements.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A drying kiln anti-accumulation cleaning device includes a kiln body, wherein a chain cleaning structure for cleaning slag from the kiln wall is provided inside the kiln body.

[0008] The chain cleaning structure includes a fixed base fixedly connected to the inner wall of the kiln body, a cleaning chain fixedly connected to the outer side of the fixed base, a counterweight fixedly connected to the tail end of the cleaning chain, and a vibrating assembly for striking the outer wall of the kiln body.

[0009] Furthermore, the rapping assembly includes four mounting bases fixedly connected to the outer wall of the kiln, arranged in a ring at equal intervals. The outer side of each mounting base is provided with a rapping hammer plate, and the inner side of each mounting base is provided with a movable pin.

[0010] Furthermore, the vibrating hammer plate is rotatably mounted on the outside of the mounting base via a movable pin, and the cross-section of the vibrating hammer plate is T-shaped.

[0011] Furthermore, a protective plate, which is made of steel, is fixedly connected to the falling position of the vibrating hammer plate to prevent deformation and damage to the outer wall of the kiln.

[0012] Furthermore, the number of fixed bases is six, and the six fixed bases are distributed in a ring at equal intervals.

[0013] Furthermore, the cleaning chain is a stainless steel chain, and the cleaning chain is in close contact with the inner wall of the kiln.

[0014] Furthermore, the counterweight is a solid iron block, and the counterweight is square in shape.

[0015] Compared with the prior art, this utility model provides a cleaning device for preventing material accumulation in a drying kiln, which has the following beneficial effects:

[0016] 1. The drying kiln anti-accumulation cleaning device, through the setting of a chain cleaning structure, can effectively lift up the slag during the clockwise rotation of the kiln body, and drive the slag into the middle and rear areas of the kiln body, effectively preventing the slag from caking inside the kiln body, thus significantly reducing the caking rate of the kiln body and effectively extending the operating cycle of the drying kiln.

[0017] 2. The drying kiln anti-accumulation cleaning device, by setting up a vibrating component, when the kiln body continues to rotate, the potential energy accumulated at the highest point of the vibrating hammer plate is converted into kinetic energy, which is used to knock off the slag material on the inner wall of the kiln, thereby effectively reducing the slag material that is caked on the inner wall of the kiln.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figures 1 to 3 The drying kiln anti-accumulation cleaning device in this embodiment includes a kiln body 1, and a chain cleaning structure for cleaning slag on the kiln wall is provided inside the kiln body 1.

[0024] The chain cleaning structure includes a fixed base 2 fixedly connected to the inner wall of the kiln body 1, a cleaning chain 3 fixedly connected to the outer side of the fixed base 2, a counterweight 4 fixedly connected to the tail end of the cleaning chain 3, and a vibrating component for striking the outer wall of the kiln body 1. Utilizing the centripetal force of the kiln body 1's own rotation, the chain cleaning structure is driven to rotate clockwise synchronously inside the kiln body 1, thereby cleaning the slag on the inner wall of the kiln body 1 over a wide area without dead angles. This effectively lifts up the slag during the clockwise rotation of the kiln body 1, allowing it to better enter the middle and rear areas of the kiln body 1, effectively preventing the slag from caking inside the kiln body 1, significantly reducing the caking rate of the kiln body 1, and effectively extending the operating cycle of the drying kiln.

[0025] In this embodiment, the rapping assembly includes four mounting bases 5 fixedly connected to the outer wall of the kiln body 1, arranged in a ring at equal intervals. A rapping hammer plate 6 is provided on the outside of the mounting base 5, and a movable pin 7 is provided on the inside of the mounting base 5. During the clockwise rotation of the kiln body 1, the mounting base 5, through the movable pin 7, causes the rapping hammer plate 6 outside the kiln body 1 to move from the lowest point to the highest point during clockwise rotation. As the rotation continues, the potential energy accumulated by the rapping hammer plate 6 at the highest point is converted into kinetic energy, which is used to strike the outer wall of the kiln body 1 to knock off the slag material on the inner wall of the kiln body 1, thereby effectively reducing the slag material that has hardened on the inner wall of the kiln body 1.

[0026] It should be noted that the vibrating hammer plate 6 is rotatably mounted on the outside of the mounting base 5 via the movable pin 7, and the cross-section of the vibrating hammer plate 6 is T-shaped.

[0027] Specifically, a protective plate 8 is fixedly connected to the falling position of the vibrating hammer plate 6 to prevent deformation and damage to the outer wall of the kiln. The protective plate 8 is made of steel plate. By setting the protective plate 8, the vibrating hammer plate 6 can be prevented from directly contacting the outer wall of the kiln body 1, thereby preventing damage to the outer wall of the kiln body 1 due to long-term knocking.

[0028] Specifically, there are six fixed bases 2, which are distributed in a ring at equal intervals.

[0029] It should be noted that the cleaning chain 3 is a stainless steel chain. The cleaning chain 3 is attached to the inner wall of the kiln body 1. The stainless steel chain has good corrosion resistance and a long service life.

[0030] Specifically, counterweight 4 is a solid iron block, and its shape is square.

[0031] The working principle of the above embodiments is as follows:

[0032] During operation, as the kiln body 1 rotates clockwise, the centripetal force of the kiln body 1 drives the chain cleaning structure to rotate clockwise synchronously inside the kiln body 1. This allows for a wide-range, thorough cleaning of the slag on the inner wall of the kiln body 1, effectively lifting the slag during the clockwise rotation and guiding it into the middle and rear areas of the kiln body 1. This effectively prevents the slag from caking inside the kiln body 1. Simultaneously, the mounting base 5, via the movable pin 7, allows the vibrating hammer 6 to rotate from the lowest point to the highest point outside the kiln body 1 during clockwise rotation. As the rotation continues, the potential energy accumulated at the highest point is converted into kinetic energy, striking the outer wall of the kiln body 1 to knock off the slag from the inner wall.

[0033] The installation, connection, or setting methods disclosed in this embodiment are all common mechanical connection methods, and any method that can achieve its beneficial effects can be implemented.
