Description

Technical Field

[0001] This utility model relates to a magnetic impurity removal device for removing metallic impurities, belonging to the field of magnetic impurity removal technology. Background Technology

[0002] The processing of tea involves multiple stages, including picking, withering, rolling, fermentation (for some types of tea), drying, and sorting and packaging. Each stage requires strict control of conditions and operational skills to ensure the high quality of the processed tea.

[0003] During tea processing, tea leaves typically come into contact with various mechanical equipment, such as twisting machines, drying machines, and mixing machines. When these machines are not properly maintained or are worn, metal parts may break off or produce debris, which can then get into the tea leaves. If these impurities cannot be removed in time, they will not only affect subsequent processing but also significantly reduce the purity and quality of the tea. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a magnetic impurity removal device for removing metal impurities. It solves the problem in the prior art that when the tea processing equipment is not properly maintained or is worn, the metal parts in the equipment will fall off or generate debris, which will mix into the tea. When the impurities in the tea cannot be removed in time, it will not only affect the subsequent tea processing process, but also greatly reduce the purity and quality of the tea.

[0005] The technical problem to be solved by this utility model is achieved by the following technical solution: a magnetic impurity removal device for removing metal impurities, including a conveyor frame and a conveyor belt for conveying tea leaves. An electromagnet plate is provided above the conveyor belt. An inverted L-shaped fixing block is fixed to the top of one side of the conveyor frame. The fixing block and the electromagnet plate are connected by a connecting block. The connecting block is vertically arranged above the conveyor belt. One end of the connecting block is integrally formed on the fixing block, and the other end has two integrally formed locking blocks on both sides. A U-shaped groove for the electromagnet plate to be inserted is opened on the side of the locking block near the electromagnet plate. A cleaning mechanism for removing impurities from the surface of the electromagnet plate is detachably provided on the surface of the conveyor belt.

[0006] One side of the conveyor frame is provided with a support plate, and a drive source for driving the conveyor belt to rotate is fixed on the support plate. In this embodiment, the drive source is a motor.

[0007] By adopting the above technical solution, when metal impurities are mixed into tea leaves and need to be removed, workers only need to energize the electromagnet plate and then transport the tea leaves to the surface of the conveyor belt. As the conveyor belt moves, the tea leaves are transported to a position below the electromagnet plate. At this point, the electromagnet plate adsorbs the metal impurities mixed into the tea leaves, causing them to adhere to its surface, thus completing the removal of metal impurities from the tea leaves. With this structure, impurities in tea leaves can be removed promptly simply by energizing the electromagnet plate, without affecting subsequent processing, and significantly improving the purity and quality of the tea leaves, making it extremely convenient.

[0008] The present invention is further configured such that: the cleaning mechanism includes fixed rods fixed to both sides of the surface of the conveyor belt, and a brush for scraping off impurities from the surface of the electromagnet plate is fixed between the two fixed rods. Both ends of the brush are integrally formed with cylinders for engaging with the outer wall of the fixed rods. Both sides of the brush are integrally formed with L-shaped strips along the length direction, and a storage cavity for impurities is formed between the strips and the brush.

[0009] By adopting the above technical solution, when residual metal impurities adhere to the surface of the electromagnet plate, simply start the motor to rotate the conveyor belt, causing the fixed rod to move along the surface of the conveyor belt towards the electromagnet plate. When the fixed rod moves to the bottom of the electromagnet plate, the brush comes into contact with the surface of the electromagnet plate. As the conveyor belt continues to rotate, the fixed rod continues to move away from the electromagnet plate, so that the brush moves against the surface of the electromagnet plate while scraping off the metal impurities. At the same time, the scraped metal impurities fall into the storage chambers on both sides, thus removing the metal impurities adhering to the surface of the electromagnet plate. The operation process is simple and very convenient.

[0010] The present invention is further configured such that: a fixed seat is integrally formed on the surface of the conveyor belt, the fixed seat and the fixed rod are detachably connected, the fixed seat is provided with a fixing groove for the fixed rod to be inserted, the outer wall of the fixed rod is provided with a number of protrusions, the fixing groove is provided with a groove for the number of protrusions to be inserted, and the fixing groove is provided with a rotating groove connected to the groove along the circumferential direction inside the fixing groove.

[0011] By adopting the above technical solution, when it is necessary to fix the fixing rod to the surface of the conveyor belt, simply insert the fixing rod into the fixing groove. During the process of the fixing rod being inserted into the fixing groove, the protrusion is aligned and inserted into the groove. When the protrusion moves to the connection between the groove and the rotating groove, the fixing rod causes the protrusion to be inserted into the rotating groove. The rotating groove limits the protrusion, preventing the fixing rod from detaching from the fixing seat, thereby making the fixing rod stably fixed to the surface of the conveyor belt.

[0012] The present invention is further configured such that: an impurity collection box is placed on one side of the conveyor frame, and one side of the impurity collection box extends to the bottom of the conveyor frame.

[0013] By adopting the above technical solution, when the fixed rod moves to the edge of the impurity collection box near the conveyor belt, the fixed rod tilts towards the impurity collection box, so that the metal impurities in the storage chamber fall into the impurity collection box, avoiding the pollution of the working environment by the metal impurities, which is very convenient.

[0014] The beneficial effects of this invention are as follows: When metallic impurities are mixed into tea leaves and need to be removed, workers only need to energize the electromagnet plate and then transport the tea leaves to the surface of the conveyor belt. As the conveyor belt moves, the tea leaves are transported to the area below the electromagnet plate. At this point, the electromagnet plate adsorbs the metallic impurities mixed into the tea leaves, causing them to adhere to its surface, thus completing the removal of metallic impurities from the tea leaves. With this structure, impurities in tea leaves can be removed promptly simply by energizing the electromagnet plate, without affecting subsequent processing, and significantly improving the purity and quality of the tea leaves, making it extremely convenient.

[0019] To facilitate a clear understanding of the technical means, creative features, objectives, and effects of this utility model, the following description, in conjunction with specific illustrations, further elaborates on this utility model.

[0020] like Figure 1As shown, a magnetic impurity removal device for removing metal impurities includes a conveyor frame 1 and a conveyor belt 2 for conveying tea leaves. An electromagnet plate 3 is arranged above the conveyor belt 2. An inverted L-shaped fixing block 4 is fixed to the top of one side of the conveyor frame 1. The fixing block 4 and the electromagnet plate 3 are connected by a connecting block 5. The connecting block 5 is vertically arranged above the conveyor belt 2. One end of the connecting block 5 is integrally formed on the fixing block 4, and the other end has two integrally formed locking blocks 6 on both sides. The locking block 6 has a U-shaped groove 7 for the electromagnet plate 3 to be inserted on the side near the electromagnet plate 3. A cleaning mechanism for removing impurities from the surface of the electromagnet plate 3 is detachably provided on the surface of the conveyor belt 2.

[0021] In this embodiment, a support plate 8 is provided on one side of the conveyor frame 1, and a drive source 9 for driving the conveyor belt 2 to rotate is fixed on the support plate 8. In this embodiment, the drive source 9 is a motor.

[0022] When metallic impurities are mixed into tea leaves and need to be removed, workers simply energize the electromagnet plate 3 and then transport the tea leaves to the surface of the conveyor belt 2. As the conveyor belt 2 moves, the tea leaves are transported to below the electromagnet plate 3. At this point, the electromagnet plate 3 adsorbs the metallic impurities mixed into the tea leaves, causing them to adhere to its surface, thus completing the removal of metallic impurities from the tea leaves. With this structure, impurities in tea leaves can be removed promptly simply by energizing the electromagnet plate 3, without affecting subsequent processing, and significantly improving the purity and quality of the tea leaves, making it extremely convenient.

[0023] When too much metal impurity accumulates on the surface of the electromagnet plate 3 and needs to be removed, the staff first removes the tea leaves from the surface of the conveyor belt 2, then disconnects the power supply to the electromagnet plate 3, thereby releasing the electromagnet plate 3's attraction to the metal impurities. This causes the metal impurities to fall from the surface of the electromagnet plate 3 onto the surface of the conveyor belt 2, whereby cleaning tools such as brushes and vacuum cleaners are used to clean the metal impurities from the surface of the conveyor belt 2.

[0024] In addition, the cleaning mechanism can remove impurities adhering to the surface of the electromagnet plate 3, so as to remove metal impurities from the tea leaves in the next batch. This prevents excessive accumulation of impurities on the surface of the electromagnet plate 3, thus not reducing the magnet's adsorption capacity, and making the impurity removal effect of the tea leaves that are subsequently transported more obvious.

[0025] like Figure 2 and Figure 3 As shown, the cleaning mechanism includes fixed rods 10 fixed to both sides of the surface of the conveyor belt 2. A brush 11 for scraping impurities from the surface of the electromagnet plate 3 is fixed between the two fixed rods 10. Both ends of the brush 11 are integrally formed with cylinders 12 for engaging with the outer wall of the fixed rods 10. Both sides of the brush 11 are integrally formed with L-shaped strips 13 along the length direction. A waste storage cavity 14 is formed between the strips 13 and the brush 11.

[0026] When residual metal impurities adhere to the surface of the electromagnet plate 3, simply start the motor to rotate the conveyor belt 2, causing the fixed rod 10 to move along the surface of the conveyor belt 2 toward the electromagnet plate 3. When the fixed rod 10 moves to below the electromagnet plate 3, the brush 11 comes into contact with the surface of the electromagnet plate 3. As the conveyor belt 2 continues to rotate, the fixed rod 10 continues to move away from the electromagnet plate 3, so that the brush 11 moves while abutting against the surface of the electromagnet plate 3, scraping off the metal impurities from the surface of the electromagnet plate 3. At the same time, the scraped metal impurities fall into the impurity storage cavities 14 on both sides, thus removing the metal impurities adhering to the surface of the electromagnet plate 3. The operation process is simple and very convenient.

[0027] like Figure 2 As shown, a fixed seat 16 is integrally formed on the surface of the conveyor belt 2. The fixed seat 16 is detachably connected to the fixed rod 10. A fixing groove 17 for the fixed rod 10 to be inserted is provided on the fixed seat 16. Several protrusions 18 are provided on the outer wall of the fixed rod 10. A groove 19 for the several protrusions 18 to be inserted is provided in the fixing groove 17. A rotating groove 20 communicating with the groove 19 is provided in the fixing groove 17 along the circumferential direction.

[0028] When it is necessary to fix the fixing rod 10 to the surface of the conveyor belt 2, simply insert the fixing rod 10 into the fixing groove 17. During the process of inserting the fixing rod 10 into the fixing groove 17, the protrusion 18 is aligned and inserted into the groove 19. When the protrusion 18 moves to the connection between the groove 19 and the rotating groove 20, the fixing rod 10 causes the protrusion 18 to be inserted into the rotating groove 20. The rotating groove 20 limits the protrusion 18, preventing the fixing rod 10 from detaching from the fixing seat 16, thereby making the fixing rod 10 stably fixed to the surface of the conveyor belt 2.

[0029] When it is necessary to remove the fixing rod 10 from the surface of the conveyor belt 2, simply rotate the fixing rod 10 so that the protrusion 18 rotates out of the rotating groove 20. When the protrusion 18 moves to the connection between the groove 19 and the rotating groove 20, pull the fixing rod 10 out of the fixing groove 17. The fixing rod 10 can then be easily removed from the surface of the conveyor belt 2. The operation is very convenient.

[0030] like Figure 1 As shown, a waste collection box 15 is placed on one side of the conveyor frame 1, and one side of the waste collection box 15 extends to the bottom of the conveyor frame 1.

[0031] When the fixed rod 10 moves to the edge of the conveyor belt 2 near the impurity collection box 15, the fixed rod 10 tilts towards the impurity collection box 15, so that the metal impurities in the storage cavity fall into the impurity collection box 15, avoiding the pollution of the working environment by the metal impurities, which is very convenient.

Those skilled in the art should understand that this utility model is not limited to the above embodiments, and various changes and modifications can be made without departing from the spirit and scope of this utility model.
