[0001] This utility model relates to the technical field of dextrin feeding, specifically a dust suppression device for dextrin feeding based on forced negative pressure adsorption. Background Technology

[0002] Dextrin is a polysaccharide obtained by partial hydrolysis of starch. It is often used as a thickener, stabilizer or filler to improve the taste and shelf life of food. Caramelized dextrin is dextrin that has been roasted. During the feeding process of caramelized dextrin, dust will be generated, so it is necessary to use appropriate dust suppression devices to remove the dust.

[0003] As disclosed in announcement number CN215353248U, a dust suppression device for the feeding process of coke dextrin includes a slurry tank. Dust suppression nozzles are installed inside the slurry tank. The dust suppression nozzles are connected in sequence to a flow regulating valve, a flow meter, and a centrifugal pump via a water inlet pipe. The flow regulating valve and flow meter work together to control the water flow rate. This utility model has a simple overall structure and good dust removal effect.

[0004] However, in the prior art, the angle of the dust hood is mostly fixed, which is inconvenient to rotate and adjust the angle of the dust hood according to the actual dust suppression position. Moreover, the dust is adsorbed and collected on the dust screen, and the disassembly and cleaning of the dust screen is inconvenient. The dust screen is prone to clogging during long-term use, as is the case in the comparative patents listed above.

[0005] To address this issue, we propose a dust suppression device for feeding dextrin based on forced negative pressure adsorption. Utility Model Content

Moreover, the dust is adsorbed and collected on the dustproof net, making the disassembly and cleaning of the dustproof net inconvenient, and the dustproof net is prone to clogging during long-term use.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a dust suppression device for feeding dextrin based on forced negative pressure adsorption, comprising a fixed bracket, a dust collection hood hinged to the upper end of the fixed bracket, and a negative pressure fan installed at the bottom of the dust collection hood;

[0029] 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.

[0030] Please see Figures 1-6 The present invention provides the following technical solution.

[0031] Example 1: To address the problem in existing technologies where the angle of the dust hood 2 is mostly fixed, making it inconvenient to adjust the angle of the dust hood 2 according to the actual dust suppression position, this example provides a dust suppression device for dextrin feeding based on forced negative pressure adsorption. The device includes a fixed support 1, a dust hood 2, and a movable column 6. The fixed support 1 is bolted to the feeding assembly of the equipment used for processing dextrin. The dust hood 2 is rotatably connected to the upper end of the fixed support 1. Simultaneously, the movable column 6 is fixedly connected to the front side of the dust hood 2, and the movable column 6 is rotatably connected to the front side of the upper end of the fixed support 1. Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, firstly, based on the dust location of the coke dextrin feeding, the dust hood 2 is rotated. The dust hood 2 rotates at the upper end of the fixed bracket 1, and the dust hood 2 drives the movable column 6 to rotate between the fixed bracket 1, so that the dust hood 2 is directly facing the dust location, thereby achieving a better dust control effect.

[0032] Example 2: To address the problems existing in the prior art, this example provides a dust suppression device for dextrin feeding based on forced negative pressure adsorption. The device includes a connecting mechanism 3, a fixing block 8, a connecting rod 9, a spring 10, and a baffle 11. The connecting mechanism 3 is located at the front end of the fixed support 1 and is used to limit the movement between the dust collection hood 2 and the fixed support 1. The connecting mechanism 3 consists of an auxiliary block 4, a fixing rod 5, a movable column 6, and a fixing groove 7. The movable column 6 is fixedly connected to the front side of the dust collection hood 2 and rotatably connected to the front side of the upper end of the fixed support 1. Multiple fixing grooves 7 are formed in the middle of the movable column 6. An auxiliary block 4 is provided below and is fixedly connected to the front side of the upper end of the fixed bracket 1. A fixed rod 5 for limiting is hinged to the middle of the auxiliary block 4. The fixed rod 5 is engaged in the fixed groove 7 at the corresponding position, and the upper end of the fixed rod 5 is engaged in the fixed block 8. The fixed block 8 is located at the upper end of the movable column 6 and is fixedly connected to the fixed bracket 1. A connecting rod 9 is fixedly connected to the right end of the fixed block 8, and a spring 10 is sleeved on the outer surface of the connecting rod 9. A baffle 11 is fixedly connected to the movable end of the spring 10, and the baffle 11 and the connecting rod 9 form a left-right sliding structure. The baffle 11 is fitted against the upper end of the fixed rod 5. Figure 1 , Figure 2 , Figure 4 and Figure 5As shown, after the position of the dust hood 2 is adjusted, by pulling the baffle 11, the baffle 11 slides between the baffle 11 and the connecting rod 9, and the baffle 11 compresses the spring 10, causing the spring 10 to undergo elastic deformation. Then, the fixing rod 5 is flipped upward, and the fixing rod 5 slides between the fixing rod 5 and the auxiliary block 4. At this time, the fixing rod 5 is engaged in the fixing groove 7 at the corresponding position, limiting the movement between the movable column 6 and the fixed bracket 1, thereby facilitating the limitation between the dust hood 2 and the fixed bracket 1. At the same time, the upper end of the fixing rod 5 is engaged in the fixing block 8. Then, the baffle 11 is released directly. At this time, the spring 10 returns to its elastic deformation, pushing the baffle 11 to slide between the connecting rod 9, so that the baffle 11 is fitted against the front side of the upper end of the fixing rod 5, limiting the limitation between the fixing rod 5 and the fixing block 8, and preventing the fixing rod 5 from falling out of the fixing groove 7.

[0033] Example 3: To address the problems in the prior art where dust is adsorbed and collected on the dustproof net 14, making disassembly and cleaning of the dustproof net 14 inconvenient, and the dustproof net 14 is prone to clogging during long-term use, this example provides a dust suppression device for dextrin feeding based on forced negative pressure adsorption. The device includes a negative pressure fan 12, a fan hood 13, a dustproof net 14, an auxiliary pull rod 15, a movable rod 16, and a stop block 17. The negative pressure fan 12 is fixedly installed at the bottom of the dust collection hood 2. The suction end of the negative pressure fan 12 is connected to the fan hood 13, and the fan hood 13 is connected to the left end of the dust collection hood 2. The stop block 17 is fixedly connected to the left end of the movable rod 16, and the movable rod 16 is rotatably connected to the front and rear sides of the upper end of the dust collection hood 2. A torsion spring is provided at the connection between the movable rod 16 and the dust collection hood 2. Figure 1 , Figure 2 and Figure 6 As shown, a negative pressure is created by the negative pressure fan 12 to adsorb the dust during the feeding process of the coke dextrin. The dust is adsorbed and collected on the dust screen 14. When it is necessary to clean the dust on the dust screen 14, the movable rod 16 is rotated. The movable rod 16 rotates at the upper end of the dust suction hood 2. The torsion spring at the connection between the movable rod 16 and the dust suction hood 2 undergoes elastic deformation. The movable rod 16 drives the stop block 17 to rotate and disengage from the dust screen 14, thereby releasing the limit between the dust screen 14 and the dust suction hood 2. Then, the auxiliary pull rod 15 is pulled upward to move the dust screen 14 out of the dust suction hood 2, which facilitates the disassembly and cleaning of the dust screen 14.
