Description

Technical Field

[0001] This utility model relates to the field of filter aid processing technology, and in particular to a dehydration filter aid calcination device. Background Technology

[0002] Dehydrating filter aids are auxiliary substances used to improve filtration efficiency and promote material dehydration. In industrial production, when processing suspensions or slurries containing a large amount of water, dehydrating filter aids are often used to reduce the moisture content of the filter cake and improve production efficiency. Their working principle is mainly through adsorption on the surface of material particles, changing the surface properties of the particles, making the material change from hydrophilic to hydrophobic, thus facilitating the smooth flow of water out of the material pores, thereby achieving the effect of dehydration and filtration. Common dehydrating filter aids include diatomaceous earth and perlite, which are widely used in mining, chemical, and environmental protection fields. The production process of dehydrating filter aids requires the use of a calcination device.

[0003] However, during the calcination process of dehydration filter aids, raw materials containing high viscosity components or water of crystallization are prone to softening, melting, or chemical reactions at high temperatures, producing viscous substances. This causes the materials to clump together, stick to the walls, and block the furnace tubes and discharge ports, leading to frequent shutdowns for cleaning, reduced production efficiency, increased maintenance costs, and even potential safety accidents due to localized overheating. Furthermore, equipment components are prone to corrosion and wear under high-temperature conditions, affecting the service life of the equipment. Utility Model Content

[0004] The purpose of this invention is to solve the problems in the existing technology where raw materials containing high viscosity components or water of crystallization are prone to softening, melting, or chemical reactions at high temperatures during the roasting process of dehydrating filter aids, resulting in the formation of viscous substances, causing material agglomeration, sticking to the walls, clogging furnace tubes and discharge ports, leading to frequent shutdowns for cleaning, reduced production efficiency, increased maintenance costs, and even the possibility of safety accidents due to local overheating. Furthermore, equipment components are prone to corrosion and wear under high-temperature environments, affecting the service life of the device. Therefore, this invention proposes a roasting device for dehydrating filter aids.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: a dehydration filter aid calcination device, comprising a base, a support, a furnace body, a servo motor, a feed pipe, and a discharge device. The support is fixed to the upper surface of the base, the servo motor is fixed to one end of the support, the drive end of the servo motor is fixedly connected to the furnace body, and the end of the furnace body away from the servo motor is rotatably connected to the support. The feed pipe is fixed to the upper surface of the furnace body, and the discharge device is disposed on one side of the furnace body. The discharge device includes a discharge pipe, which is fixedly connected to the furnace body. The inner surface of the discharge pipe... A filter plate is fixedly connected to the wall. A cylinder is fixedly connected to one end of the discharge pipe. The drive end of the cylinder passes through the discharge pipe and is fixedly connected to a push plate. A pipe body is fixedly connected to one side of the discharge pipe. A rotating rod is rotatably connected to the inner wall of the pipe body. A blade is fixedly connected to the surface of the rotating rod. By setting up a discharge device, efficient discharge and automatic processing of materials can be achieved. It can separate qualified particles from agglomerated materials. Mechanical extrusion and crushing operations break up agglomerated materials and discharge them, reducing the accumulation of agglomerated materials and affecting subsequent production, ensuring smooth discharge, reducing manual intervention, and improving production efficiency.

[0006] Preferably, the pipe is inclined and connected to the discharge pipe. By setting the pipe, it receives the agglomerated material accumulated on the filter plate, provides space for crushing the agglomerated material, and crushes the agglomerated material through the internal rotating blades. The crushed material is then discharged through the discharge port, thereby achieving effective treatment of the agglomerated material, reducing the blockage of the discharge channel by the agglomerated material, and ensuring the smooth progress of the discharge process.

[0007] Preferably, a DC motor is fixedly connected to one side of the tube body, and the drive end of the DC motor is fixedly connected to the rotating rod. By setting the DC motor, the rotating rod is driven to rotate the blades, which crushes the agglomerated material accumulated on the filter plate, so that it can be discharged through the discharge port, reducing the blockage of the filter plate and discharge channel by the agglomerated material, ensuring the smooth discharge process, and improving the efficiency of material processing and the practicality of the device.

[0008] Preferably, a discharge port is provided on one side of the pipe body, and there are multiple blades arranged in a linear array. By setting the blades, the sticky agglomerated materials generated by high temperature softening, melting or chemical reaction are crushed during the discharge process, so that they are turned into qualified particles and discharged through the discharge port, reducing the blockage of the pipeline by agglomerated materials and ensuring the smooth operation of the discharge device.

[0009] Preferably, the inner wall of the furnace body is provided with a scraping assembly. The scraping assembly includes a connecting frame, which is fixedly connected to a bracket. A main shaft is fixedly connected to the surface of the connecting frame. By setting up the scraping assembly, the relative static state of the main shaft and the scraper is utilized. The rotation of the furnace body causes the scraper to continuously scrape off the material adhering to the inside of the furnace body, reducing material adhesion to the wall, ensuring uniform heating and normal flow of the material inside the furnace, reducing problems such as agglomeration and blockage caused by wall adhesion, and improving roasting efficiency and equipment operation stability.

[0010] Preferably, a through hole is provided at one end of the furnace body near the main shaft, and the main shaft is inserted into the through hole on one side of the furnace body. By setting the main shaft, the main shaft serves as the fixed shaft of the scraper and is connected to the furnace body through a bearing or sealing structure to ensure that the scraper is stably located in a specific position inside the furnace.

[0011] Preferably, a scraper is fixedly connected to the surface of the main shaft. The scraper contacts the inner wall of the furnace body. By setting the scraper, it remains stationary when the furnace body is driven to rotate by the servo motor. The relative motion generated by the rotation of the furnace body scrapes off the material adhering to the inside of the furnace body, preventing the material from sticking to the wall. This solves the problems of agglomeration caused by material adhesion, affecting the roasting effect and subsequent material discharge, and ensures the normal flow of materials inside the furnace body and processing efficiency.

[0012] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0013] 1. In this utility model, by setting up a discharge device, during the processing of filter aid, the material is poured into the furnace body through the feed pipe, and then the furnace body is heated and the servo motor is started simultaneously. The servo motor drives the furnace body to rotate, which in turn stirs the material inside the furnace body. After heating is completed, the material is discharged through the discharge pipe. The qualified granules of the material pass through the filter plate and are discharged, while the agglomerated material accumulates on the filter plate. The cylinder is started, and the cylinder drives the push plate to squeeze the agglomerated material into the tube body. Then, the DC motor is started and drives the rotating rod to drive the blade to rotate and crush the agglomerated material. Then it is discharged through the discharge port. By setting up a discharge device, the efficient discharge and automatic processing of materials are achieved. It can separate qualified granules from agglomerated materials. The mechanical squeezing and crushing operations break the agglomerated material and discharge it, reducing the impact of agglomerated material accumulation on subsequent production, ensuring smooth discharge, reducing manual intervention, and improving production efficiency.

[0014] 2. In this utility model, by setting a scraping component, the main shaft and scraper remain stationary while the furnace body rotates driven by the servo motor. However, due to the rotation of the furnace body, the scraper scrapes off the material adhering to the inside of the furnace body, preventing the material from sticking to the furnace wall. By setting a scraping component, the material adhering to the inside of the furnace body can be automatically scraped off by the principle of relative motion when the furnace body rotates, preventing the material from sticking to the wall. This effectively reduces problems such as reduced internal space of the furnace body, uneven heat transfer, and difficulty in cleaning caused by material sticking to the wall, maintaining the cleanliness of the inside of the furnace body and ensuring the stable operation of the roasting process.

[0022] Please see Figures 1-6 This utility model provides a technical solution: a dehydration filter aid calcination device, including a base 1, a support 2, a furnace body 3, a servo motor 4, a feed pipe 5, and a discharge device 6. The support 2 is fixed on the upper surface of the base 1, the servo motor 4 is fixed on one end of the support 2, the drive end of the servo motor 4 is fixedly connected to the furnace body 3, the end of the furnace body 3 away from the servo motor 4 is rotatably connected to the support 2, the feed pipe 5 is fixed on the upper surface of the furnace body 3, and the discharge device 6 is set on one side of the furnace body 3.

[0023] In this implementation scheme: the discharge device 6 includes a discharge pipe 61, which is fixedly connected to the furnace body 3. A filter plate 64 is fixedly connected to the inner wall of the discharge pipe 61. A cylinder 62 is fixedly connected to one end of the discharge pipe 61. The drive end of the cylinder 62 passes through the discharge pipe 61 and is fixedly connected to a push plate 63. A pipe body 65 is fixedly connected to one side of the discharge pipe 61. A rotating rod 68 is rotatably connected to the inner wall of the pipe body 65. A blade 67 is fixedly connected to the surface of the rotating rod 68. By setting up the discharge device 6, efficient discharge and automatic processing of materials can be achieved. It can separate qualified particles from agglomerated materials. Through mechanical extrusion and crushing operations, agglomerated materials are crushed and discharged, reducing the accumulation of agglomerated materials that affect subsequent production, ensuring smooth discharge, reducing manual intervention, and improving production efficiency.

[0024] Specifically, the pipe body 65 is inclined and connected to the discharge pipe 61. By setting the pipe body 65, it receives the agglomerated material accumulated on the filter plate 64, provides space for the crushing of the agglomerated material, and crushes the agglomerated material through the internal rotating blades 67. The crushed material is then discharged through the discharge port 610, thereby achieving effective treatment of the agglomerated material, reducing the blockage of the discharge channel by the agglomerated material, and ensuring the smooth progress of the discharge process.

[0025] Specifically, a DC motor 66 is fixedly connected to one side of the tube 65. The drive end of the DC motor 66 is fixedly connected to the rotating rod 68. By setting the DC motor 66, the rotating rod 68 is driven to rotate the blade 67, which crushes the agglomerated material accumulated on the filter plate 64, so that it can be discharged through the discharge port 610. This reduces the blockage of the filter plate 64 and the discharge channel by the agglomerated material, ensures the smooth discharge process, and improves the efficiency of material processing and the practicality of the device.

[0026] Specifically, a discharge port 610 is provided on one side of the pipe body 65, and there are multiple blades 67 arranged in a linear array. By setting the blades 67, the sticky agglomerated materials generated by high temperature softening, melting or chemical reaction are crushed during the discharge process, so that they are turned into qualified particles and discharged through the discharge port 610, reducing the blockage of the pipeline by agglomerated materials and ensuring the smooth operation of the discharge device 6.

[0027] Specifically, the inner wall of the furnace body 3 is provided with a scraping component 69. The scraping component 69 includes a connecting frame 691, which is fixedly connected to the support 2. A main shaft 692 is fixedly connected to the surface of the connecting frame 691. By setting up the scraping component 69, the main shaft 692 and the scraper 693 are relatively stationary. The furnace body 3 rotates to make the scraper 693 continuously scrape off the material adhering to the inside of the furnace body 3, thereby reducing the material sticking to the wall, ensuring that the material inside the furnace is heated evenly and flows normally, reducing problems such as agglomeration and blockage caused by sticking to the wall, and improving the roasting efficiency and equipment operation stability.

[0028] Specifically, a through hole is provided at one end of the furnace body 3 near the main shaft 692, and the main shaft 692 is inserted into the through hole on one side of the furnace body 3.

[0029] In this embodiment: by setting a main shaft 692, which serves as the fixed shaft of the scraper 693, and connecting it to the furnace body 3 through bearings or a sealing structure, the scraper 693 is ensured to be stably positioned in a specific position inside the furnace.

[0030] Specifically, a scraper 693 is fixedly connected to the surface of the main shaft 692, and the scraper 693 contacts the inner wall of the furnace body 3.

[0031] In this embodiment: by setting a scraper 693, which remains stationary when the servo motor 4 drives the furnace body 3 to rotate, the relative motion generated by the rotation of the furnace body 3 is used to scrape off the material adhering to the inside of the furnace body 3, thereby preventing the material from sticking to the wall and solving the problems of agglomeration caused by material adhesion, affecting the roasting effect and subsequent material discharge, and ensuring the normal flow of material inside the furnace body 3 and processing efficiency.

[0032] Working principle: By setting up the discharge device 6, when processing the filter aid, the material is poured into the furnace body 3 through the feed pipe 5. Then, the furnace body 3 is heated and the servo motor 4 is started at the same time. The servo motor 4 drives the furnace body 3 to rotate, which drives the material inside the furnace body 3 to stir. After heating is completed, the material is discharged through the discharge pipe 61. The qualified granules pass through the filter plate 64 and are fed out, while the agglomerated material accumulates on the filter plate 64. The cylinder 62 is started and drives the push plate 63 to squeeze the agglomerated material into the pipe body 65. Then, the DC motor 66 is started and drives the rotating rod 68 to drive the blade 67 to rotate and crush the agglomerated material. Then it is discharged through the discharge port 610. By setting up the discharge device 6, the material is efficiently discharged and automatically processed. It can separate qualified granules and agglomerated material. The mechanical extrusion and crushing operation breaks the agglomerated material and discharges it, reducing the impact of agglomerated material accumulation on subsequent production, ensuring smooth discharge, reducing manual intervention, and improving production efficiency.

[0033] By setting up the scraping component 69, while the furnace body 3 is rotated by the servo motor 4, the main shaft 692 and the scraper 693 remain stationary. However, due to the rotation of the furnace body 3, the scraper 693 scrapes off the material adhering to the inside of the furnace body 3, preventing the material from sticking to the furnace wall. By setting up the scraping component 69, the material adhering to the inside of the furnace body 3 can be automatically scraped off by the principle of relative motion when the furnace body 3 is rotating, preventing the material from sticking to the wall. This effectively reduces problems such as reduced internal space of the furnace body 3, uneven heat transfer, and difficulty in cleaning caused by material sticking to the wall, maintaining the cleanliness of the inside of the furnace body 3 and ensuring the stable operation of the roasting process.
