[0003] Patent CN103597306B discloses a pulverizing and drying device. This device pulverizes materials by rotating hammers and includes a heated air supply port within the pulverizing section, allowing the pulverized material to circulate and dry in a grading section, thus integrating pulverizing and drying operations. This design can improve material handling efficiency and simplify the process to a certain extent.

[0004] However, during the implementation of the relevant technology, the above-mentioned pulverizing and drying device was found to have the following problems: the heating air flow path of the device is relatively simple, resulting in insufficient drying uniformity and a tendency for localized overheating or incomplete drying of the material. Furthermore, the device lacks an effective dust recovery system, leading to significant dust emission during operation, which may affect the working environment and pose a potential threat to the health of operators. Therefore, we propose an improved drying device with pulverizing function. Utility Model Content

Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0024] Example 1:

[0025] like Figures 1 to 4As shown, the drying device with pulverizing function provided in this embodiment mainly includes: a support structure 1, which adopts a metal frame structure to provide structural support for internal components; a pulverizing component 2, which includes a cylindrical shell 201, which is fixed by bolts through the support structure 1, and has a feed inlet 5 at the top; a heating component 3, which is a double-layer shell structure composed of an integrated air guide channel and multiple sets of heating columns 301, and undertakes the material drying function; and a collection component 4, which is equipped with a cubic filter chamber 401 and is connected to the lower part of the shell 201 by bolts, and has a built-in dust recovery system.

[0026] In this embodiment, efficient processing is achieved through the synergistic effect of functional components: after the material enters the crushing component 2 through the feed inlet 5 and is crushed, it is dried in the spiral guiding drying airflow formed by the heating component 3, and then falls into the filter chamber 401; after being graded by a multi-layer filter screen, qualified material is discharged through the outlet, while the crushing dust is intercepted and recycled. This integrated system optimizes airflow distribution through air guide channels, ensures material transmission through hinged linkage guiding components, and achieves environmentally friendly recycling through multi-layer filtration, significantly improving the uniformity of material processing, energy efficiency ratio, and environmental friendliness.

[0027] Example 2:

[0028] Based on Example 1, in order to improve the cutting efficiency and blade durability of the crushing component, a rotating shaft 204 with a serrated blade assembly 205 and an annular air guide groove 203 are added inside the housing 201 to achieve simultaneous operation of multi-stage crushing and airflow drying.

[0029] Specifically, the crushing component 2 includes: a crushing chamber 202, which is located inside the housing 201, and an air guide groove 203 is formed between the crushing chamber 202 and the hollow area of ​​the housing 201; a rotating shaft 204, whose top end vertically penetrates the housing 201 and is rigidly connected to the output shaft of the drive motor 206, and a plurality of blade groups 205 are evenly distributed along the circumference of the rotating shaft 204.

[0030] In this embodiment, the crushing chamber 202 adopts a cylindrical structure, and the air guide groove 203 is an annular groove disposed in the annular gap between the housing 201 and the crushing chamber 202; the blade assembly 205 is composed of multiple cutting units, arranged at equal intervals along the axial direction of the rotating shaft 204. The drive motor 206 drives the rotating shaft 204 and the blade assembly 205 to rotate at high speed through the output shaft, thereby performing multi-stage crushing of the material in the crushing chamber 202; the air guide groove 203 serves as the airflow channel of the heating component 3, realizing the simultaneous operation of the material crushing and drying processes.

[0031] Specifically, the blade assembly 205 is made of high-hardness alloy steel, and its surface is uniformly coated with a wear-resistant coating, with the edges carefully designed as a serrated structure.

[0032] This design, with its high-hardness alloy steel material and wear-resistant coating forming a dual protection system, comprehensively enhances the wear and corrosion resistance of the blade assembly 205 from the material substrate to the surface protective layer, significantly improving its durability. The serrated structure at the edges optimizes the geometry of the cutting contact surface, generating a more concentrated stress distribution during the cutting process, effectively improving the cutting and crushing efficiency of various materials. At the same time, by reducing performance degradation caused by excessive wear, it further extends the actual service life of the blade assembly.

[0033] Example 3:

[0034] Based on Example 1, in order to enhance the thermal stability and safety of the drying process, a ceramic PTC heating column 301 and an intelligent temperature control system are integrated in the air guide duct 203, which, together with the air inlet 302 and the exhaust fan 303, form a dynamic thermal balance adjustment mechanism.

[0035] Specifically, the heating component 3 includes: a plurality of heating columns 301 evenly distributed around the air guide groove 203; an air inlet 302 located on one side of the housing 201 for introducing cold air; and an exhaust fan 303 located on the other side of the housing 201 for discharging hot air.

[0036] In this embodiment, when the internal temperature of the housing 201 is detected to exceed the preset threshold, the heating column 301 automatically cuts off the heat source and stops working. At this time, the air inlet 302 starts the physical air cooling mechanism to introduce external cold air. At the same time, under the action of negative pressure, the exhaust fan 303 starts the forced convection circulation to realize the rapid cooling process of heat exchange inside the housing.

[0037] Specifically, the heating column 301 adopts a ceramic PTC heating element with positive temperature coefficient characteristics. The heating column 301 is cylindrical and is axially symmetrically distributed radially along the annular flow channel of the air guide groove 203.

[0038] With this configuration, the heating column 301 of the ceramic PTC heating element heats up after being energized, and the heat is evenly transferred to the crushing chamber 202 through the air guide groove 203 to achieve material drying. It has the characteristics of rapid heating and stable temperature.

[0039] Example 4:

[0040] Based on Example 1, in order to optimize the efficiency of material classification and dust recovery, a dust removal system that is linked with a hinged baffle plate 402 and an exhaust fan 405 is configured in the filter chamber 401, and a detachable dust removal box 407 is added to achieve convenient cleaning and maintenance.

[0041] Specifically, the collection assembly 4 includes: a filter chamber 401, which is fixedly connected to the housing 201 by bolts; two guide plates 402, which are connected by hinges and distributed vertically inside the filter chamber 401; a discharge port 403 located at the end of the filter chamber 401; a dust discharge port 404, located at the bottom of the housing 201 and the top of the filter chamber 401, for discharging large particles; and a fan 405, one end of which is connected to the dust discharge port 404 and the other end of which is connected to the dust collection box 406.

[0042] In this embodiment, the pulverized and dried material falls into the filter chamber 401 and moves towards the discharge port 403 under the guidance of the guide plate 402; at the same time, the negative pressure generated by the exhaust fan 405 draws large particulate impurities into the dust discharge box 406 through the dust discharge port 404, thereby achieving efficient separation of material and impurities.

[0043] Specifically, the top of the dust collection box 406 is provided with several exhaust filter holes, and the bottom is connected to the dust collection box 407 by a buckle for discharging accumulated dust.

[0044] This design allows dust in the dust collection box 406 to be concentrated and deposited in the dust collection box 407, while the exhaust filter effectively intercepts and filters fine dust in the exhaust gas. Regularly disassembling and cleaning the dust collection box 407 ensures the entire device remains in good cleanliness and maintains high efficiency.

[0045] Working principle: In actual use, the material to be processed is fed into the top of the support structure 1 through the feed inlet 5 and falls directly into the crushing chamber 202 inside the housing 201 of the crushing component 2. After the material is in place, the drive motor 206 starts, driving the rotating shaft 204 to rotate at high speed, and the blade assembly 205 mounted on the rotating shaft 204 rotates at high speed accordingly. The wear-resistant coating on the surface of the blades and the serrated structure on the edges work together to apply force to the material from multiple directions, achieving efficient cutting and crushing.

[0046] During the crushing operation, the heating component 3 begins to operate. The heating column 301 is precisely controlled to the preset temperature by the temperature control system, and the generated hot air is evenly distributed through the air guide grooves 203 surrounding the crushing chamber 202 and the hollow part of the housing 201. The hot air forms a spiral airflow along the rotation direction of the blade assembly 205, fully covering the crushing chamber 202 and acting evenly on the surface of the material to achieve efficient drying. When the internal temperature of the housing 201 exceeds the set threshold, the heating column 301 automatically stops heating, the air inlet 302 introduces cold air, and the exhaust fan 303 discharges the hot air, cooling and ventilating the inside of the housing 201 to maintain stable operation of the equipment.

[0047] If the particle size of the crushed and dried material meets the requirements, it will pass through the filter chamber 401 and fall from the crushing chamber 202 into the collection component 4 below. The filter chamber 401 is bolted to the housing 201. Two guide plates 402 arranged vertically inside guide the material to slide down in a stepped manner, and finally discharge it from the discharge port 403 at the end. During this process, the exhaust fan 405 runs continuously. One end of the fan is connected to the dust discharge port 404 at the bottom of the housing 201 and the top of the filter chamber 401 through a pipe, which sucks the dust and large particulate impurities generated during the operation into the dust collection box 406. The exhaust filter hole at the top of the dust collection box 406 intercepts the dust in the gas, causing the dust to settle at the bottom of the box. The user can clean it regularly through the dust collection box 407 connected by a snap fastener.

[0048] The various components of the equipment work in close coordination: the support structure 1 and the feed inlet 5 are responsible for material introduction; the crushing component 2 relies on the drive motor 206, the rotating shaft 204, and the blade assembly 205 to complete efficient crushing; the heating component 3 uses the air guide duct 203 and the heating column 301 to achieve uniform drying and precise temperature control; the collection component 4 completes material collection and dust treatment through the guide plate 402, the exhaust fan 405, and the dust collection box 406. The entire equipment is bolted together to ensure structural stability; the wear-resistant coating and serrated design of the blades improve service life; the spiral airflow optimizes drying uniformity; and the dust recovery mechanism improves the working environment, demonstrating high efficiency and environmental friendliness in the material handling process.

[0049] It should be noted that all electrical components mentioned in this article are connected to an external main controller and 220V AC mains power. The main controller can be a conventional known device that can be controlled by a computer or other means. The detailed description of known functions and known components is omitted in the specific implementation of this disclosure. In order to ensure the compatibility of the device, the operating methods used are consistent with the parameters of commercially available instruments.
