Description

Technical Field

[0001] This utility model relates to the technical field of dichlorobenzyl production equipment, specifically a feed auger for dichlorobenzyl production raw materials. Background Technology

[0002] p-Dichlorobenzyl is an important chemical raw material, and its production process requires the accurate and stable delivery of various raw materials to the reaction equipment. Currently, the commonly used feeding device is the screw conveyor, however, existing feeding screws have some problems in actual use.

[0003] On the one hand, due to differences in particle size, moisture content, and other characteristics of the raw materials used in the production of benzyl dichlorobenzyl, some raw materials tend to stick to the auger blades, resulting in poor material feeding and affecting production efficiency. On the other hand, existing feeding augers are difficult to precisely control the amount of material fed during the conveying process and cannot be flexibly adjusted according to the requirements of the production process, which in turn affects the production quality of benzyl dichlorobenzyl.

[0004] Therefore, it is necessary to provide a screw conveyor for feeding raw materials in the production of benzyl dichloroethylene to solve the above-mentioned technical problems. Utility Model Content

[0005] The purpose of this invention is to provide a feed auger for the production of benzyl dichloroethylene, so as to solve the problems mentioned in the background art.

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

[0007] A feed auger for the production of benzyl dichloroethylene, comprising:

[0008] The auger housing has a feed pipe fixedly installed on one side of its outer surface and a discharge pipe fixedly installed on one side of its outer surface. A flow sensor is installed inside the discharge pipe. An auger shaft is rotatably installed inside the auger housing. Spiral blades are fixedly installed on the outer wall of the auger shaft. A drive motor is fixedly installed at one end of the auger housing, and the drive end of the drive motor passes through the auger housing and extends into the interior of the auger housing, where it is fixedly connected to one end of the auger shaft.

[0009] The inner wall of the auger housing and the outer surface of the spiral blades are both provided with an anti-stick coating, and the anti-stick coating is made of polytetrafluoroethylene material.

[0010] Preferably, a feeding hopper is fixedly installed at the top of the feeding pipe, and a guide cover is fixedly installed at the top of the feeding hopper by bolts. A stirring shaft is rotatably installed inside the feeding hopper, and several stirring rollers are fixedly installed on the outer wall of the stirring shaft. A stirring motor is fixedly installed on the outer surface of the feeding hopper, and the drive end of the stirring motor passes through the feeding hopper and extends into the interior of the feeding hopper and is fixedly connected to one end of the stirring shaft.

[0011] Preferably, symmetrically distributed support columns are fixedly installed between the lower side of the outer surface of the hopper and the outer wall of the auger shell.

[0012] Preferably, a support plate is provided below the auger shell, a fixed column is fixedly installed on one side of the top of the support plate, a groove is provided on the top of the fixed column, a rotating shaft is rotatably installed inside the groove, a movable column is fixedly installed on the outer wall of the rotating shaft, and the top of the movable column is fixedly connected to the lower side of the outer surface of the auger shell, and an angle adjustment mechanism is provided on the other side of the top of the support plate.

[0013] Preferably, symmetrically distributed casters are fixedly installed on both sides of the bottom of the support plate.

[0014] Preferably, the angle adjustment mechanism includes a hydraulic telescopic rod, which is rotatably mounted on the other side of the top of the support plate, and the drive end of the hydraulic telescopic rod is hinged to the lower side of the outer wall of the auger housing.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] 1. This utility model utilizes the combined use of an auger housing, discharge pipe, feed pipe, drive motor, spiral blades, auger shaft, and flow sensor. By coating the inner wall of the auger housing and the surface of the spiral blades with an anti-stick coating, the adhesion between the raw material and the auger components is significantly reduced, effectively preventing material sticking and ensuring smooth material feeding, thereby improving production efficiency. Simultaneously, the drive motor is a variable frequency motor, allowing the rotational speed to be changed by adjusting the motor's operating frequency. Combined with real-time monitoring and feedback of the raw material flow rate from the flow sensor, the feeding amount can be precisely controlled according to the specific requirements of the dichlorobenzyl production process, thereby improving the production quality of dichlorobenzyl.

[0017] 2. This utility model utilizes the combined use of a feeding hopper, a stirring motor, a guide cover, a stirring shaft, and a stirring roller. The rotating stirring roller applies mechanical force to the raw materials entering the feeding hopper, thoroughly stirring and dispersing any potentially lumpy materials. This stirring and dispersing operation effectively breaks down the agglomeration structure formed between raw materials due to moisture, compression, and other factors, preventing clumping and ensuring the raw materials remain in a loose state. This allows them to smoothly pass through the feed pipe into the auger shell, further improving the stability and reliability of the entire feeding process.

[0018] 3. This utility model utilizes a combination of a support plate, a hydraulic telescopic rod, a fixed column, a movable column, a rotating shaft, and a groove. By precisely controlling the extension and retraction of the hydraulic telescopic rod, it enables accurate adjustment of the tilt angle of the auger shell. This device can be flexibly adapted to different discharge angle requirements in actual production, significantly improving its flexibility and applicability in practical applications.

[0028] Please see Figures 1-4 One embodiment provided by this utility model:

[0029] A feed auger for the production of benzyl dichloroethylene, comprising:

[0030] The auger housing 1 has a feed pipe 3 fixedly installed on one side above the outer surface of the auger housing 1, and a discharge pipe 2 fixedly installed on one side below the outer surface of the auger housing 1. A flow sensor 20 is installed inside the discharge pipe 2. An auger shaft 13 is rotatably installed inside the auger housing 1. Spiral blades 12 are fixedly installed on the outer wall of the auger shaft 13. A drive motor 7 is fixedly installed at one end of the auger housing 1, and the drive end of the drive motor 7 passes through the auger housing 1 and extends into the interior of the auger housing 1, and is fixedly connected to one end of the auger shaft 13.

[0031] The inner wall of the auger housing 1 and the outer surface of the spiral blades 12 are both provided with an anti-stick coating, which is made of polytetrafluoroethylene material. This coating can significantly reduce the adhesion between the raw material and the surface of the auger components, effectively prevent the raw material from sticking together, and ensure the smoothness of the feeding process.

[0032] A feeding hopper 4 is fixedly installed at the top of the feeding pipe 3. A guide cover 6 is fixedly installed at the top of the feeding hopper 4 by bolts. A stirring shaft 14 is rotatably installed inside the feeding hopper 4. Several stirring rollers 15 are fixedly installed on the outer wall of the stirring shaft 14. A stirring motor 5 is fixedly installed on the outer surface of the feeding hopper 4. The drive end of the stirring motor 5 passes through the feeding hopper 4 and extends into the interior of the feeding hopper 4 and is fixedly connected to one end of the stirring shaft 14. The guide cover 6 is detachable, which makes it convenient to replace the guide cover 6 of different specifications during the feeding process of the reaction equipment at different angles to ensure that the raw materials enter the interior of the feeding hopper 4 stably.

[0033] In one embodiment, symmetrically distributed support columns 8 are fixedly installed between the lower side of the outer surface of the hopper 4 and the outer wall of the auger housing 1, which improves the stability of the hopper 4.

[0034] In one preferred embodiment, a support plate 9 is provided below the auger housing 1. A fixing column 11 is fixedly installed on one side of the top of the support plate 9. A groove 19 is provided on the top of the fixing column 11. A rotating shaft 18 is rotatably installed inside the groove 19. A movable column 17 is fixedly installed on the outer wall of the rotating shaft 18. The top of the movable column 17 is fixedly connected to the lower side of the outer surface of the auger housing 1. An angle adjustment mechanism is provided on the other side of the top of the support plate 9.

[0035] In one embodiment, symmetrically distributed casters 16 are fixedly installed on both sides of the bottom of the support plate 9, which facilitates the movement and adjustment of the device and enhances its flexibility and operability.

[0036] In one preferred embodiment, the angle adjustment mechanism includes a hydraulic telescopic rod 10, which is rotatably mounted on the other side of the top of the support plate 9. The drive end of the hydraulic telescopic rod 10 is hinged to the lower side of the outer wall of the auger housing 1, which can flexibly adjust the tilt angle of the auger housing 1 to adapt to different discharge requirements and improve the flexibility of the device.

[0037] The working principle of this utility model is as follows: The entire device is controlled by a main control button. Since the equipment matched with the control button is common equipment and belongs to existing common knowledge technology, its electrical connection relationship and specific circuit structure will not be described in detail here. The parts of this device not mentioned are the same as or can be implemented using existing technology. During use, the raw material for producing benzyl dichloroisocyanurate enters the auger shell 1 through the feed pipe 3. At this time, the drive motor 7 is started. The drive end of the drive motor 7 drives the auger shaft 13 to rotate, and the rotation of the auger shaft 13 in turn drives the spiral blades 12 to rotate synchronously. With the help of the rotation of the spiral blades 12, the raw material entering the auger shell 1 is conveyed axially towards the discharge pipe 2, and finally the raw material is output through the discharge pipe 2. When the raw material flows through the discharge pipe 2, the flow sensor 20 set inside the discharge pipe 2 will monitor the flow rate of the raw material through the discharge pipe 2 in real time and accurately, thereby realizing the material discharge operation. By coating the inner wall of the auger housing 1 and the surface of the spiral blades 12 with an anti-stick coating, the adhesion between the raw material and the auger components can be significantly reduced, effectively preventing material sticking and ensuring smooth material feeding, thereby improving production efficiency. Simultaneously, the drive motor 7 is a variable frequency motor, allowing the rotational speed to be changed by adjusting the motor's operating frequency. Combined with real-time monitoring and feedback of the raw material flow rate from the flow sensor 20, the feeding amount can be precisely controlled according to the specific requirements of the dichlorobenzyl production process, thereby improving the production quality of dichlorobenzyl.

[0038] When the device is put into operation, the raw material for the production of benzyl dichloroisocyanurate is orderly discharged into the hopper 4 through the guide cover 6. As the raw material begins to enter the hopper 4, the stirring motor 5 starts simultaneously. The drive end of the stirring motor 5 drives the stirring shaft 14 to rotate in a circular motion. The rotation of the stirring shaft 14, in turn, drives the connected stirring roller 15 to rotate synchronously. The rotating stirring roller 15 applies mechanical force to the raw material entering the hopper 4, thoroughly stirring and dispersing any potentially agglomerated material. This stirring and dispersing operation effectively breaks down the agglomerated structure formed between raw materials due to moisture, compression, and other factors, preventing agglomeration and ensuring that the raw material remains in a loose state. This allows it to smoothly pass through the feed pipe 3 into the auger shell 1, further improving the stability and reliability of the entire feeding process.

[0039] When the device is activated, the hydraulic telescopic rod 10 can be operated. The drive end of the hydraulic telescopic rod 10 extends and retracts, using the movable column 17 as a transmission component, allowing the auger housing 1 to rotate around the rotating shaft 18. By precisely controlling the extension and retraction of the hydraulic telescopic rod 10, the tilt angle of the auger housing 1 can be accurately adjusted. This device can be flexibly adapted to different discharge angle requirements in actual production, significantly improving the flexibility and applicability of the device in practical applications.

[0040] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
