Abstract
Description
Technical Field
[0001] This utility model relates to the field of pellet mill equipment technology, and in particular to a swing-type pellet mill. Background Technology
[0002] In the pharmaceutical, food processing, and chemical industries, pellet mills are commonly used equipment to convert powdery materials into uniform granules. The gyratory pellet mill, as one type, is widely used due to its simple structure and ease of operation.
[0003] However, in actual production, the moisture content of the material from the previous process is often not optimal, resulting in inconsistent particle size and irregular shape when granulated by the rotating drum and screen. Therefore, after the material enters the pellet mill, the rotating drum inside the mill is used to agitate the material and adjust its moisture content. When the material moisture content is too high or too low to granulate, manual adjustment of the moisture content is necessary, leading to low production efficiency. Utility Model Content
[0004] To address the shortcomings of existing technologies, this utility model provides a swing pellet mill, aiming to solve the problem that existing swing pellet mills cannot granulate materials with excessively high or low moisture content, resulting in low production efficiency.
[0005] To solve the above problems, the technical solution adopted by this utility model is as follows: a gyratory pellet mill, including a hopper, a stirring drum fixedly installed in the hopper, the hopper having an inlet and an outlet, a sieve plate fixedly installed at the outlet, a controller fixedly installed on the outer wall of the hopper, the stirring drum including stirring blades and a stirring shaft, a humidification chamber opened in the stirring shaft, a humidification hole opened on the side wall of the stirring shaft, the humidification chamber being connected to the humidification hole, a one-way valve fixedly installed in the humidification hole, the one-way valve being electrically connected to the controller, a heating chamber opened in the stirring blades, a heating wire fixedly installed in the heating chamber, the heating wire being electrically connected to the controller, and a humidity sensor fixedly installed on the outer wall of the stirring shaft, the humidity sensor being electrically connected to the controller.
[0006] The principle of this scheme is as follows:
[0007] A humidification and heating device is installed on the stirring drum in the hopper. Specifically, a humidification chamber is opened in the stirring shaft, and a humidification hole is opened on the side wall of the stirring shaft. The humidification hole is connected to the humidification chamber, and a one-way valve is fixedly installed in the humidification hole. The one-way valve ensures one-way transmission between the humidification chamber and the material in the hopper, preventing the material from entering the humidification chamber. A heating chamber is opened in the stirring blade, and a heating wire is fixedly installed in the heating chamber. A humidity sensor is fixedly installed on the outer wall of the stirring shaft. The humidity sensor detects the humidity of the material in the hopper, and the controller controls the heating wire and the one-way valve to operate, thereby adjusting the humidity of the material in the hopper.
[0008] The beneficial effects of this plan are:
[0009] By installing humidification and heating in the mixing drum, when the material humidity in the hopper is detected to be too high, the material can be heated by heating wire to reduce the humidity. When the material humidity in the hopper is detected to be too low, the material can be humidified by heating wire to increase the humidity. In addition, the humidity of the material is detected in real time by a humidity sensor to ensure that the humidity of the material is at the optimal granulation humidity.
[0010] Furthermore, a sealing cavity parallel to the sieve plate is formed on the inner wall of each sieve hole of the sieve plate. A spring is fixedly installed at the bottom of the sealing cavity, and a baffle is fixedly installed at the top of the spring. An electromagnet is fixedly installed at the bottom of the sealing cavity, and the electromagnet is electrically connected to the controller. When the material humidity in the hopper is not the optimal granulation humidity, the sieve holes of the sieve plate are sealed by the baffle, thereby preventing the material from being discharged from the sieve plate when the humidity is unsuitable.
[0011] Furthermore, the size of each baffle is greater than or equal to the size of the sieve aperture corresponding to that baffle. The size of the baffle being greater than or equal to the size of the sieve aperture ensures that the baffle can seal the sieve aperture.
[0012] Furthermore, a discharge trough is fixedly installed below the discharge port of the hopper, and a discharge plate is fixedly installed at the bottom of the discharge trough. The discharge plate is set in an inclined state. The discharge trough below the discharge port prevents materials from falling outside the collection tank, and the inclined state of the discharge plate can prevent materials falling from the hopper from falling directly into the collection tank and causing damage, and can also prevent materials from accumulating in the discharge trough.
[0013] Furthermore, it also includes a drive motor, the output shaft of which is fixedly connected to the stirring shaft of the drum, and the drive motor is electrically connected to a controller. The controller controls the rotation of the drive motor to drive the stirring shaft, thereby mixing and stirring the material in the hopper, thus improving the production efficiency of the pellet mill.
[0014] Furthermore, a flow detection sensor is fixedly installed at the feed inlet of the hopper, and the flow detection sensor is electrically connected to the controller. The flow sensor measures the amount of material entering the hopper, and the amount of material in the hopper is ensured based on the flow sensor's detection, thereby preventing the material from overflowing or accumulating in the hopper.

Detailed Implementation
[0019] The following detailed description illustrates the specific implementation method:
[0020] like Figure 1-3As shown, the structure of a swing-type pellet mill is as follows: It includes a hopper 101 with an inlet 1011 and an outlet 1012. A controller 401 is fixedly installed on the outer wall of the hopper 101. A mixing drum is fixedly installed inside the hopper 101. The mixing drum includes mixing blades and a mixing shaft. A humidification chamber 203 is provided in the mixing shaft, and a humidification hole 204 is provided on the side wall of the mixing shaft. The humidification chamber 203 is connected to the humidification hole 204. A one-way valve 2041 is fixedly installed in the humidification hole 204. The input end of the one-way valve 2041 is electrically connected to the output end of the controller 401. A mixing blade has a... A heating chamber 205 is provided, in which a heating wire 206 is fixedly installed. The input end of the heating wire 206 is electrically connected to the output end of the controller 401. A humidity sensor is fixedly installed on the outer wall of the stirring shaft, and the output end of the humidity sensor is electrically connected to the input end of the controller 401. A drive motor 207 is fixedly installed on one side of the hopper 101. The output shaft of the drive motor 207 is fixedly connected to the stirring shaft of the stirring drum, and the input end of the drive motor 207 is electrically connected to the output end of the controller 401. The rotation of the drive motor 207 drives the stirring drum to rotate, thereby stirring the material in the hopper 101 and mixing the material.
[0021] A screen plate 102 is fixedly installed at the discharge port 1012 of the hopper 101. A sealing cavity 104 parallel to the screen plate 102 is opened on the inner side wall of each screen hole 103 of the screen plate 102. A spring 196 is fixedly installed at the bottom of the sealing cavity 104. A baffle 107 is fixedly installed at the top of the spring 196. An electromagnet 105 is fixedly installed at the bottom of the sealing cavity 104. The input end of the electromagnet 105 is electrically connected to the output end of the controller 401. The size of each baffle 107 installed in each screen hole 103 is greater than or equal to the size of the corresponding screen hole 103, so as to ensure that the baffle 107 extends out of the sealing cavity 104 and can block the corresponding screen hole 103, so that the material in the hopper 101 cannot fall down through the screen hole 103.
[0022] Furthermore, a discharge trough 301 is fixedly installed below the hopper 101, and a discharge plate 302 is fixedly installed at the bottom of the discharge trough 301. The discharge plate 302 is inclined in the discharge trough 301 to ensure that the material falling from the hopper 101 can continue to fall under the inclination of the discharge plate 302, thereby avoiding the accumulation of material in the discharge trough 301.
[0023] Meanwhile, a flow detection sensor 208 is fixedly installed at the feed inlet 1011 of the feed port. The output end of the flow detection sensor 208 is electrically connected to the input end of the controller 401. The flow detection sensor 208 detects the amount of material entering the hopper 101, thereby controlling the amount of material fed into the hopper 101 through the controller 401, so as to avoid the increase in production power consumption due to insufficient material in the hopper 101 or the overflow due to excessive material.
[0024] Specific implementation process:
[0025] During the production process, the initial state of the baffle 107 is to seal the screen plate 102. When the material is fed into the pellet mill, the humidity of the material in the hopper 101 is detected by a humidity sensor. If the humidity of the material in the hopper 101 is too high, the material can be heated by the heating wire 206 to reduce the humidity. If the humidity of the material in the hopper 101 is too low, the material can be humidified by the heating wire 206 to increase the humidity. The humidity of the material is also detected in real time by the humidity sensor to ensure that the humidity of the material is the optimal granulation humidity. When the humidity sensor detects that the humidity of the material is the optimal granulation humidity, the controller 401 controls the electromagnet 105 in the sealed cavity 104 of the screen plate 102 to be energized, so that the baffle 107 sealed in the screen hole 103 of the screen plate 102 is retracted into the sealed cavity 104, so that the material can fall from the screen plate 102 to complete the granulation of the material.
[0026] Meanwhile, during the granulation process, the material entering the hopper 101 is detected by the flow detection sensor 208, thereby preventing the material from overflowing from the hopper 101 due to excessive material being fed into it.
