Description

Technical Field

[0001] This utility model belongs to the field of attapulgite powder production technology, specifically relating to a drying mechanism for an attapulgite powder production line. Background Technology

[0002] Attapulgite powder is a powdered product made from high-quality attapulgite through mineral processing, drying, grinding and other processes. In the current technology, placing attapulgite powder on the conveyor belt of the production line will cause residual dust to dirty the conveyor belt, and some large particles of impurities will fall directly to the ground during the conveying process, requiring workers to clean them up, which increases the workload of the workers.

[0003] Therefore, a drying device for an attapulgite powder production line, with announcement number "CN221630310U", includes a shell, a drying chamber fixedly installed on the top of the shell, two rotating shafts rotatably mounted on the inner wall of the shell, conveyor belts mounted on the two rotating shafts, a rotating column rotatably mounted on the inner wall of the shell parallel to one of the rotating shafts, a transmission mechanism between the rotating column and the rotating shaft, a roller fixedly mounted on the rotating column, and brushes evenly arranged on the rollers. A scraper is fixedly mounted on the side of the shell. By installing the scraper, during the conveyor belt conveying process, the scraper can scrape off particulate impurities adhering to the conveyor belt, which then fall into the dust collection box along the inclined scraper. The installation of brushes facilitates cleaning of the conveyor belt, ensuring that the dust on the conveyor belt is cleaned and kept clean.

[0004] However, for the drying device used in the above-mentioned attapulgite powder production line, although the attapulgite powder is placed on the conveyor belt, the motor drives the rotating shaft to rotate, and the rotating shaft drives the conveyor belt to rotate, so that the attapulgite powder on the conveyor belt passes through the drying box for drying, there are still the following obvious defects in the use of the above-mentioned drying device: In the process of conveying and drying attapulgite powder using the conveyor belt, the attapulgite powder is spread flat on the conveyor belt and kept static for drying. Because the attapulgite powder is in a static state and has a certain thickness when it is spread flat for drying, the drying hot air cannot penetrate the spread attapulgite powder to completely dry it. Utility Model Content

[0005] The purpose of this invention is to provide a drying mechanism for an attapulgite powder production line to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a drying mechanism for an attapulgite powder production line, comprising:

[0007] A drying conveyor frame is provided at the end of which a conveyor line for conveying and drying attapulgite powder is provided. At the bottom end of the conveyor line and in a groove provided at the end of the drying conveyor frame, a cleaning box is provided for scraping and cleaning the surface residue of the conveyor belt in the conveyor line. The discharge end of the drying conveyor frame is covered with a splash-proof discharge cover.

[0008] A conveyor frame is mounted on top of a drying conveyor frame and through which a conveyor line passes to convey and dry attapulgite powder. Inside the conveyor frame is an insulated drying box through which the conveyor belt of the conveyor line passes to dry the attapulgite powder. Inside the insulated drying box are elliptical rollers that rotate evenly and intermittently vibrate the attapulgite powder conveyed on the conveyor line.

[0009] Preferably, tension rollers are provided at both ends of the groove at the end of the drying conveyor frame, and the tension rollers tension the conveyor belt at the lower end of the conveyor line, so that the tensioned conveyor belt is conducive to residual scraping and cleaning operations, and prevents attapulgite powder residue from remaining on the surface of the conveyor line, thus avoiding waste.

[0010] Preferably, a feeding hopper is provided through the bottom inner side of the anti-splash feeding cover on one side of the drying conveyor frame, and a receiving frame is provided at the vertically corresponding position of the feeding hopper's discharge end. The anti-splash feeding cover is attached to the outside of the discharge end of the conveyor line, so that the attapulgite powder is prevented from splashing in all directions during vertical feeding, thus reducing waste.

[0011] Preferably, the lower end of the conveyor belt in the conveyor line passes through the cleaning box, and a scraper roller is rotatably provided on one side of the inside of the heat-insulating drying box, which is attached to the surface of the conveyor belt after the conveyor belt is fed. One end of the rotating shaft of the scraper roller is connected to a motor A installed outside the cleaning box, so that the scraper roller scrapes and cleans the residual attapulgite powder on the surface of the conveyor line.

[0012] Preferably, a brush cleaning roller is rotatably provided on one side inside the heat-insulating drying box to clean the surface of the conveyor line, and one end of the brush cleaning roller has a shaft that extends to the outside of the cleaning box and is connected to a motor B, so that the brush cleaning roller cleans the surface of the conveyor line where the scraping material is cleaned.

[0013] Preferably, one end of the cleaning box extends through to the bottom outer side of the drying conveyor frame, and a cleaning receiving frame is provided on the bottom side of the insulated drying box perpendicular to the bottom, which can collect the attapulgite powder from scraping and rotating cleaning.

[0014] Preferably, the elliptical rollers are evenly arranged on the upper inner side of the conveyor line. The rotating shafts of the elliptical rollers are driven to the outside of the heat-insulating drying box and are connected to a motor C. A hot air hood is provided through the end of the heat-insulating drying box, and an air outlet plate is provided inside the hot air hood. The air outlet plate is evenly provided with hot air outlet holes, so that the elliptical rollers intermittently lift the conveyor belt and shake the attapulgite powder, thereby achieving thorough drying of the attapulgite powder as it is turned over on the conveyor line.

[0015] Preferably, a fan is provided on one side of the upper end face of the conveying frame, and a gas heater is provided on the output insulation pipe of the fan. The gas heater is connected to the hot air hood through a gas pipe, so that the external gas is processed and enters the gas heater for heating.

[0016] Compared with the prior art, the technical effects and advantages of this utility model are as follows: The drying mechanism of this attapulgite powder production line uses an elliptical roller set by a motor C inside an insulated drying box. The elliptical roller is evenly arranged on the upper end of the inner side of the conveyor belt in the conveyor line. When the attapulgite powder is conveyed to the insulated drying box for drying, the motor C drives the elliptical roller to rotate, which intermittently vibrates the conveyor belt of the conveyor line. This causes the attapulgite powder to vibrate and turn over on the conveyor line. In this way, the attapulgite powder can be thoroughly penetrated and dried by hot air during the intermittent vibration during conveying, further ensuring the drying quality of the produced attapulgite powder.

[0017] A splash guard is attached to the discharge end of the conveyor line, and a hopper is installed on the drying conveyor frame inside the splash guard. During the vertical feeding of attapulgite powder, the splash guard blocks the attapulgite powder that splashes in all directions, allowing the powder to be collected in the receiving frame through the hopper. Furthermore, the scraper roller and brush cleaning roller in the cleaning box can scrape and clean the surface of the conveyor line after feeding. The scraper roller scrapes and cleans the surface of the conveyor line after feeding, and the brush cleaning roller rotates and sweeps the surface to collect the powder in the cleaning receiving frame. This reduces the amount of attapulgite powder residue on the conveyor line, keeps the conveyor line clean and tidy, and reduces attapulgite powder waste. Attached Figure Description

[0023] 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.

[0024] Please see Figure 1-4 This utility model provides a technical solution: a drying mechanism for an attapulgite powder production line, comprising:

[0025] The drying conveyor frame 1 has a conveyor line 2 at one end for conveying and drying attapulgite powder. The conveyor line 2 is driven by a conveyor belt through conveyor rollers at both ends of the drying conveyor frame 1 to convey the attapulgite powder. The conveyor rollers are driven by an external servo motor. The two sides of the conveyor line 2 are provided with upward-protruding material-blocking rubber strips to prevent the attapulgite powder from splashing outwards during small-amplitude shaking. At the bottom of the conveyor line 2 and in a groove at the end of the drying conveyor frame 1, there is a cleaning box 3 for scraping and cleaning the surface residue of the conveyor belt in the conveyor line 2. The cleaning box 3 allows the conveyor line 2 to pass through to scrape and clean the residual attapulgite powder and prevent the cleaned attapulgite powder from spreading outwards. The discharge end of the drying conveyor frame 1 is covered with a splash-proof discharge cover 4. The splash-proof discharge cover 4 is set on the conveyor roller at one end of the conveyor line 2 to block and prevent splashing during discharge.

[0026] The conveyor frame 5 is mounted on the upper end of the drying conveyor frame 1 and allows the conveyor line 2 to pass through it for conveying and drying attapulgite powder. The conveyor line 2 is partially covered to reduce the diffusion of hot air to the outside. Inside the conveyor frame 5, there is an insulated drying box 6 for the conveyor belt of the conveyor line 2 to pass through for drying attapulgite powder. The insulated drying box 6 is equipped with elliptical rollers 7 that rotate evenly and intermittently vibrate the attapulgite powder conveyed on the conveyor line 2, so that the conveyor line 2 vibrates during the conveying of attapulgite powder, which is beneficial for the hot air drying treatment of attapulgite powder.

[0027] Tensioning rollers 8 are provided at both ends of the groove at the end of the drying conveyor frame 1 to tension the conveyor line 2 of the cleaning section for scraping and cleaning, preventing the conveyor line 2 from concave. The tensioning rollers 8 also tension the conveyor belt at the lower end of the conveyor line 2. A hopper 9 is provided through the bottom of the inner side of the anti-splash discharge cover 4 on one side of the drying conveyor frame 1, allowing the dried attapulgite powder to fall into the receiving frame 10 through the hopper 9. The receiving frame 10 is located vertically corresponding to the discharge end of the hopper 9 to collect the dried attapulgite powder. The anti-splash discharge cover 4 covers the hopper 1. On the outside of the discharge end of the conveyor line 2, the lower end of the conveyor belt in the conveyor line 2 passes through the cleaning box 3 to facilitate scraping and cleaning of the conveyor line 2 after material discharge. Inside the heat preservation drying box 6, a scraper roller 11 is rotatably provided on one side, which is attached to the surface of the conveyor belt after material discharge from the conveyor line 2 to scrape off the residual attapulgite powder on the surface of the conveyor line 2, reducing waste. One end of the rotating shaft of the scraper roller 11 is connected to a motor A12 installed outside the cleaning box 3, which drives the scraper roller 11 to rotate. Scraper strips are evenly provided on the scraper roller 11.

[0028] Inside the insulated drying box 6, a brush cleaning roller 13 is rotatably installed on one side to clean the surface of the conveyor line 2. The surface of the brush cleaning roller 13 is equipped with a brush made of hard rubber to facilitate the cleaning of attapulgite powder. One end of the brush cleaning roller 13 has a rotating shaft that extends to the outside of the cleaning box 3 and is connected to a motor B14 to drive the brush cleaning roller 13 to rotate. One end of the cleaning box 3 extends to the bottom outer side of the drying conveyor frame 1, and a cleaning receiving frame 15 is provided on the bottom side of the insulated drying box 6 to collect the cleaned attapulgite powder.

[0029] Elliptical rollers 7 are evenly arranged on the upper inner side of the conveyor line 2 so that the rotation of the elliptical rollers 7 drives the attapulgite powder on the conveyor line 2 to shake and flip slightly. The rotating shaft of the elliptical rollers 7 extends through to the outside of the heat-insulating drying box 6 and is connected to a motor C16 to drive the elliptical rollers 7 to rotate. A hot air hood 17 is provided through the end of the heat-insulating drying box 6, and an air outlet plate 18 is provided inside the hot air hood 17. The air outlet plate 18 is evenly provided with hot air outlet holes 19 so that the hot air is evenly discharged to penetrate and thoroughly dry the shaking attapulgite powder, and can reduce the intensity of the hot air output. A fan 20 is provided on one side of the upper end face of the conveyor frame 5, and a gas heater 21 is provided on the output heat-insulating pipe of the fan 20. The gas heater 21 is connected through the gas pipe to the hot air hood 17 so that the external gas is heated to dry the attapulgite powder.

[0030] Specifically, during use, the conveyor line 2 is started, and the attapulgite powder to be dried is spread evenly on its surface. An external servo motor drives the conveyor line 2 to transport the attapulgite powder into the insulated drying chamber 6 of the conveyor frame 5. At this time, motor C16 drives the elliptical roller 7 to rotate on the upper inner side of the conveyor line 2. The rotation of the elliptical roller 7 causes its protruding ends to intermittently push against the conveyor line 2, causing the attapulgite powder to shake and turn slightly on the surface of the conveyor line 2. Before this, the blower 20 is started to process external gas and deliver it to the gas heater 21, converting the gas into hot gas. The hot gas is then transported through pipes to the hot air hood 17. Utilizing the large space inside the hot air hood 17, the force of the hot gas blowing is reduced, and it is discharged from the evenly distributed hot air outlets 19 on the outlet plate 18, blowing onto the shaking and turning attapulgite powder. The system allows hot air to penetrate and thoroughly dry the attapulgite powder. The insulation effect of the insulated drying box 6 accelerates the drying process. After drying, the powder is conveyed to the end of conveyor line 2 for vertical discharge. During vertical discharge, a splash guard 4 prevents the powder from spreading outwards. The falling powder then passes through the hopper 9 and lands in the receiving frame 10. After discharge from conveyor line 2, the powder passes through the tension roller 8 and enters the cleaning box 3. Motor A12 drives the scraper roller 11 to scrape and clean the residual attapulgite powder on the surface of conveyor line 2. After cleaning, motor B14 drives the brush cleaning roller 13 to clean the surface of conveyor line 2, reducing residual powder. Finally, the cleaned powder is collected inside the cleaning receiving frame 15, thus completing the conveying and drying of the attapulgite powder.

[0031] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
