Description

Technical Field

[0001] This utility model relates to the technical field of flash drying pulverizers, and in particular to a flash drying pulverizer. Background Technology

[0002] Flash dryers are a new type of continuous drying equipment that integrates drying, pulverizing, and sieving. They are particularly suitable for drying filter cake, paste, and slurry-like materials, and are commonly used in pharmaceutical production processes for pulverizing, drying, and sieving raw materials.

[0003] In the processing of pesticide suspensions, pesticide raw materials are usually placed on the grinding disc inside a flash dryer. Hot air is then blown through the holes in the grinding disc to make contact with the filter screen above for sieving and filtration. At the same time, the hot air dries the pesticide raw materials, while larger particles in the pesticide raw materials fall back down and collide with the impact blades on the grinding disc for further pulverization.

[0004] When hot air blows pesticide raw materials up, the distance between the pulverizing disc and the top filter screen cannot be adjusted. When the flash dryer pulverizer processes a small amount of pesticide raw materials, the distance between the pulverizing disc and the filter screen is too long, and the time required for the pesticide raw materials to fall back down after moving to the top of the flash dryer pulverizer is too long, which is not conducive to improving the pulverizing efficiency of pesticide raw materials. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a flash drying pulverizer, which aims to improve the problem in the prior art that the distance between the pulverizer and the top filter screen cannot be adjusted when the pesticide raw materials on the pulverizer are moved by hot air, which makes it difficult to improve the pulverization efficiency of pesticide raw materials.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a flash drying pulverizer, comprising:

[0007] The outer casing has slots on both sides of its inner sidewall.

[0008] The frame has two ends that are slidably connected to the slots. A second motor is fixedly connected to the bottom of the frame. A turntable is fixedly connected to the drive end of the second motor through the frame.

[0009] Motor 1 is fixedly connected to the bottom of the housing. A lead screw is fixedly connected to the drive end of Motor 1. The other end of the lead screw passes through the slotted sidewall and is threaded into the inside of the frame for driving the frame to move.

[0010] A feeder, fixedly connected to one side of the outer casing, is used to transport pesticide raw materials into the interior of the outer casing;

[0011] A heater, installed on the bottom outer side of the housing, is used to heat air.

[0012] As a further description of the above technical solution:

[0013] A filter screen is fixedly connected to the top wall of the outer shell for screening pesticide raw material particles.

[0014] As a further description of the above technical solution:

[0015] It also includes a cyclone separator, the bottom of which is fixedly connected to a bag filter, and the top side of the cyclone separator is connected to the top of the outer shell through a pipe for collecting pesticide raw material particles.

[0016] As a further description of the above technical solution:

[0017] A blower is fixedly connected to the top of the cyclone separator to allow air to circulate inside the casing.

[0018] As a further description of the above technical solution:

[0019] Multiple impact blades are fixedly connected to the outer top of the turntable to crush pesticide raw material particles. The turntable has through holes.

[0020] As a further description of the above technical solution:

[0021] The frame is configured as a cross-shaped structure, with the two end sidewalls of the frame fitting against the inner sidewall of the slot.

[0022] This utility model has the following beneficial effects:

[0023] In this invention, the starting motor drives the lead screw to rotate, causing the frame to move upward inside the outer shell and moving the turntable together. When the turntable moves to the top, the distance between the turntable and the filter screen at the top of the outer shell is the shortest. When the hot air blows the pesticide raw material upward, the path is smaller, and the frequency of the pesticide raw material moving between the turntable and the filter screen is more frequent. This increases the number of collisions between the pesticide raw material and the impact blades on the turntable, thereby improving the pulverization efficiency of the pesticide raw material.

[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] Reference Figure 1-3 This utility model provides an embodiment of a flash drying pulverizer, including a shell 3. A feeder 2 is fixedly connected to one side of the shell 3. The specific working principle of the feeder 2 can be referred to the feeder 2 inside the XSG-10 flash drying pulverizer. A heater 1 is installed at the bottom of the outer side of the shell 3. The specific installation structure is as follows: a hot air pipe is connected to the bottom of the outer side of the shell 3, and the other end of the hot air pipe is connected to the heater 1. When the feeder 2 is started, the pesticide raw materials are transported into the shell 3 and fall into the top of the turntable 11. At the same time, the heater 1 is started to heat the air and transport the heated gas to the bottom of the shell 3 to dry the pesticide raw materials inside the shell 3.

[0031] The inner front and rear sides of the outer shell 3 are provided with slots 7. The frame 8 is installed inside the outer shell 3. The frame 8 is set with a cross-shaped structure. The specific installation structure is as follows: both ends of the frame 8 are slidably connected inside the slots 7. The side walls of both ends of the frame 8 are in contact with the inner side walls of the slots 7 to prevent the frame 8 from rotating with the rotation of the lead screw 9. The bottom end of the frame 8 is fixedly connected to the motor 12. The drive end of the motor 12 passes through the frame 8 and is fixedly connected to the turntable 11. The outer side of the top of the turntable 11 is fixedly connected to the impact knife. The turntable 11 is provided with a through hole.

[0032] The start motor 12 drives the turntable 11 to rotate. When the turntable 11 rotates, it will throw the pesticide raw material onto the impact blade on the outside of the turntable 11 to cause collision and crush the pesticide raw material. When the turntable 11 rotates, a small amount of pesticide raw material will be thrown into the slot 7. The pesticide raw material inside the slot 7 will not affect the sliding of the two ends of the frame 8 inside the slot 7.

[0033] There is a certain gap between the outer side of the turntable 11 and the inner side wall of the outer shell 3. When the hot air at the bottom of the outer shell 3 blows upward from the gap between the turntable 11 and the inner side wall of the outer shell 3, it can blow up the pesticide raw materials on the outer side of the turntable 11 and let them fall to the middle of the turntable 11 so that the pesticide raw materials can be crushed again by the rotation of the turntable 11 and the collision of the impact blade.

[0034] A filter screen 10 is fixedly connected to the inner top wall of the outer shell 3. The specific working principle of the filter screen 10 can be referred to the filter screen 10 of the XSG-10 flash dryer pulverizer. A pipe is connected to the top of the outer shell 3, and a cyclone separator 4 is connected to the other end of the pipe. An induced draft fan is fixedly connected to the top of the cyclone separator 4. A ventilation pipe is connected to one side of the induced draft fan, and the other end of the ventilation pipe is connected to the top of the cyclone dust collector. A bag filter 5 is fixedly connected to the bottom of the cyclone separator 4. The specific working principles of the induced draft fan, cyclone separator 4 and bag filter 5 can be referred to the induced draft fan, cyclone separator 4 and bag filter 5 of the XSG-10 flash dryer pulverizer.

[0035] When the hot air inside the outer casing 3 blows the pesticide raw materials on the turntable 11 upward, the pesticide raw material particles will pass through the holes of the filter screen 10 and enter the cyclone separator 4 through the pipe. At this time, the cyclone separator 4 will separate the pesticide raw material particles attached to the hot air, and the separated pesticide raw material particles will fall into the bag dust collector 5 for collection.

[0036] A motor 6 is fixedly connected to one side of the bottom of the outer casing 3. A lead screw 9 is fixedly connected to the drive end of the motor 6. The top of the lead screw 9 extends into the slot 7. One end of the frame 8 is threaded to the outside of the lead screw 9.

[0037] Start motor 6 to rotate lead screw 9. When lead screw 9 rotates, the external thread will push frame 8 to move upward inside shell 3 and drive turntable 11 to move. When turntable 11 is at the top of shell 3, the distance between turntable 11 and filter screen 10 is the smallest. The hot air has the shortest path when blowing pesticide raw materials upward. The frequency of pesticide raw materials taking off and falling between turntable 11 and filter screen 10 is more concentrated, thereby increasing the number of collisions between pesticide raw materials and impact blades on turntable 11, thus improving the crushing efficiency of pesticide raw materials.

[0038] The reverse rotation motor 6 causes the lead screw 9 to rotate in the opposite direction, thereby pushing the frame 8 to move downward inside the outer shell 3, and driving the turntable 11 to move downward inside the outer shell 3. When the turntable 11 moves to the bottom of the outer shell 3, the distance between the turntable 11 and the filter screen 10 is the largest, so that the hot air blows the crushed and uncrushed pesticide raw materials to the top of the outer shell 3 with the longest path, increasing the drying time of the pesticide raw materials by the hot air, and making the pesticide raw materials passing through the filter screen 10 drier.

[0039] The pesticide raw materials to be crushed are poured into the feeder 2. The feeder 2 is then activated to transport the pesticide raw materials into the outer shell 3 and onto the top of the turntable 11. The motor 12 is then activated to drive the turntable 11 to rotate, throwing the pesticide raw materials on the turntable 11 to the outside of the turntable 11 to collide with the impact blades. Simultaneously, the heater 1 is activated to heat the air, and the induced draft fan is activated to circulate the air inside the outer shell 3. The hot air inside the heater 1 enters the bottom of the outer shell 3, passes through the side wall and through the holes of the turntable 11, and flows towards the top of the outer shell 3. When the air flows, it will move the pesticide raw materials on the turntable 11 together. When the pesticide raw materials move to the bottom of the filter screen 10, the particles with a diameter smaller than the holes of the filter screen 10 will pass through the holes and be transported to the cyclone separator 4 through the pipe. The cyclone separator 4 is activated to separate the pesticide raw materials from the air, and the bag dust collector 5 is used to collect the separated pesticide raw materials. Meanwhile, the larger particles on the top of the outer shell 3 will fall back onto the surface of the turntable 11 and be crushed by the impact blades on the turntable 11.

[0040] The start motor 6 drives the lead screw 9 to rotate, causing the frame 8 to move upward inside the outer shell 3, and moving the turntable 11 along with it. When the turntable 11 moves to the top of the outer shell 3, the distance between the turntable 11 and the filter screen 10 at the top of the outer shell 3 is the shortest. The hot air travels the shortest path when blowing the pesticide raw material upward, and the frequency of the pesticide raw material taking off and falling between the turntable 11 and the filter screen 10 is more concentrated, thereby increasing the number of collisions between the pesticide raw material and the impact blades on the turntable 11, thus improving the pulverization efficiency of the pesticide raw material. The reverse motor 6 drives the lead screw 9 to rotate in the opposite direction, causing the frame 8 to move downward inside the outer shell 3, and moving the turntable 11 along with it. When the turntable 11 moves to the bottom of the outer shell 3, the distance between the turntable 11 and the filter screen 10 is the largest. The hot air travels the longest path when blowing the pulverized and uncrushed pesticide raw material to the top of the outer shell 3, increasing the drying time of the pesticide raw material by the hot air, and making the pesticide raw material passing through the filter screen 10 drier.

[0041] 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.
