Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of cyclone mill equipment, specifically an anti-clogging device for hammer cyclone mills. Background Technology
[0002] The hammer mill is a high-efficiency, small-scale pulverizing device that integrates impact crushing and pneumatic separation. Its core principle is to crush materials through the impact of high-speed rotating hammers, and to achieve integrated crushing and separation operations using a built-in airflow system and grading screens. Characterized by its compact structure and strong adaptability, this equipment is an ideal choice for processing various brittle and medium-hard materials in small-scale production.
[0003] In actual operation, excessive material moisture can cause serious equipment blockage. Moisture causes powder to adhere to the surface of the hammers, the pores of the screen, and the airflow channels, forming cumulative adhesion, which ultimately disrupts the gas-solid two-phase flow balance, resulting in a sharp drop in crushing efficiency or even shutdown.
[0004] There is an urgent need to develop specialized anti-clogging devices to address the bottlenecks caused by humidity. Utility Model Content
[0005] To address the existing problems, this utility model provides an anti-clogging device for hammer cyclone mills, which solves the problem mentioned in the background art that current hammer cyclone mills are prone to clogging due to excessive material moisture.
[0006] To address the existing problems, this utility model provides a hammer cyclone mill anti-clogging device, including a hammer cyclone mill body, a support frame provided on one side of the hammer cyclone mill body, a drying conveying assembly fixedly connected to the support frame, a discharge pipe connected to the discharge end of the drying conveying assembly, the other end of the discharge pipe extending above the feed inlet of the hammer cyclone mill body, a hopper fixedly connected to the upper rear end of the drying conveying assembly, and a humidity sensor provided on the inner wall of the hopper;
[0007] The drying and conveying assembly includes a housing fixedly connected to the upper end of a support frame. The housing is hollow and contains a fixed cylinder. Ventilation holes are provided on the wall of the fixed cylinder. A spiral conveying auger is rotatably installed inside the fixed cylinder. The rear end shaft of the spiral conveying auger passes through the rear end of the fixed cylinder and is fixedly connected to the output shaft of a drive motor. The front end shaft of the spiral conveying auger is rotatably connected to a limiting member fixedly connected to the front end of the fixed cylinder. Several exhaust holes are provided on the upper wall of the housing. A hot air blower is fixedly connected to the bottom rear end of the housing.
[0008] Furthermore, a baffle plate is slidably connected to the lower side wall of the hopper, the rear end of the baffle plate is fixedly connected to the telescopic rod of the electric cylinder, and the fixed end of the electric cylinder is fixedly connected to the machine housing through a fixing component.
[0009] Furthermore, the drive motor, hot air blower, humidity sensor, and electric cylinder are all connected to a PLC controller.
[0010] Furthermore, the front and rear ends of the housing are provided with mounting ports that are adapted to the outer diameter of the fixed cylinder, and the outer walls of the front and rear ends of the fixed cylinder are fixedly connected to the mounting ports.
[0011] Furthermore, the bottom outlet of the hopper is connected to the interior of the fixed cylinder.
[0012] Compared with the prior art, the beneficial effects of this utility model are:
[0013] 1. This utility model is equipped with a feeding hopper, a humidity sensor, a baffle plate, an electric cylinder, a fixing component, and a discharge pipe. The humidity sensor detects the humidity of the material in the feeding hopper and transmits the data to the PLC controller. When the humidity of the material exceeds the threshold, the PLC controller controls the electric cylinder to pull the baffle plate outward from the outside of the feeding hopper, causing the material to fall into the drying and conveying assembly. After being dried and conveyed to the discharge pipe, the material enters the hammer cyclone mill body for crushing and grinding. Since the humidity of the material is reduced after drying, it will not cause blockage of the hammer cyclone mill. Attached Figure Description

[0020] 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.
[0021] Please see Figure 1-5 The anti-clogging device for the hammer cyclone mill includes a hammer cyclone mill body 1. A support frame 2 is provided on one side of the hammer cyclone mill body 1. A drying conveying assembly 3 is fixedly connected to the support frame 2. One end of the discharge pipe 4 is connected to the discharge end of the drying conveying assembly 3. The other end of the discharge pipe 4 extends to the upper part of the feed inlet 101 of the hammer cyclone mill body 1. A hopper 5 is fixedly connected to the upper rear end of the drying conveying assembly 3. A humidity sensor 6 is provided on the inner wall of the hopper 5.
[0022] The drying and conveying assembly 3 includes a housing 301 fixedly connected to the upper end of the support frame 2. The housing 301 is hollow inside and has a fixed cylinder 302. The fixed cylinder 302 has ventilation holes 303 on its wall. A spiral conveying auger 304 is rotatably installed inside the fixed cylinder 302. The rear end shaft of the spiral conveying auger 304 passes through the rear end of the fixed cylinder 302 and is fixedly connected to the output shaft of the drive motor 305. The front end shaft of the spiral conveying auger 304 is rotatably connected to a limiting member 306 fixedly connected to the front end of the fixed cylinder 302. Several exhaust holes 307 are provided on the upper wall of the housing 301. A hot air blower 308 is fixedly connected to the bottom of the rear end of the housing 301.
[0023] Furthermore, a baffle plate 7 is slidably connected to the lower side wall of the hopper 5. The rear end of the baffle plate 7 is fixedly connected to the telescopic rod of the electric cylinder 8. The fixed end of the electric cylinder 8 is fixedly connected to the housing 301 through a fastener 9.
[0024] Furthermore, the drive motor 305, the hot air blower 308, the humidity sensor 6, and the electric cylinder 8 are all connected to a PLC controller.
[0025] Furthermore, the front and rear ends of the housing 301 are provided with mounting ports 3021 that are adapted to the outer diameter of the fixed cylinder 302, and the outer walls of the front and rear ends of the fixed cylinder 302 are fixedly connected to the mounting ports 3021.
[0026] Furthermore, the bottom outlet of the hopper 5 is connected to the interior of the fixed cylinder 302.
[0027] Working principle: In the initial state, the hopper 5 contains material to be ground. A humidity sensor 6 installed on the inner wall of the hopper 5 detects the humidity of the material and transmits the humidity data to the PLC controller. When the humidity of the material exceeds the threshold set in the PLC controller, the PLC controller controls the electric cylinder 8 to pull the baffle plate 7 towards the outside of the hopper 5, causing the material in the hopper 5 to fall into the fixed cylinder 302. Simultaneously, the hot air blower 308 and the drive motor 305 are started. The output shaft of the drive motor 305 drives the screw conveyor 304 to slowly move the material in the fixed cylinder 302 towards the discharge pipe 4. 04 When rotating, its blades push the material forward and also cause the material to tumble. At the same time, the PLC controller controls the hot air blown out by the hot air blower 308 to enter the housing 301 from the bottom of the rear end. The hot air enters through the vent 303 on the lower wall of the fixed cylinder 302 and passes through the material at the bottom of the fixed cylinder 302. The hot air dries the material and discharges the moisture in the material through the vent 303 and exhaust port 307 on the upper wall of the fixed cylinder 302. The dried material gradually approaches the discharge pipe 4 as the screw conveyor 304 rotates, and finally exits from the discharge pipe 4 and enters the feed inlet 101, where it is crushed and ground by the hammer cyclone mill body 1. Since the humidity of the material is detected before entering the hammer cyclone mill body 1, the material exceeding the humidity threshold is dried and conveyed by the drying and conveying component 3. Therefore, the humidity of the material entering the hammer cyclone mill body 1 is greatly reduced, thus preventing the hammer cyclone mill from clogging.
[0028] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model in any way. Those skilled in the art can readily implement this utility model based on the accompanying drawings and the above description. However, any modifications, alterations, or equivalent variations made by those skilled in the art without departing from the scope of the utility model's technical solution, utilizing the disclosed technical content, are considered equivalent embodiments of this utility model. Furthermore, any equivalent changes, alterations, or variations made to the above embodiments based on the essential technology of this utility model are still within the protection scope of this utility model's technical solution.
