Description

Technical Field

[0001] This utility model relates to the field of material crushing equipment technology, specifically to a self-cleaning, anti-clogging crusher. Background Technology

[0002] Traditional crushers are prone to screen clogging during the screening process due to material adhesion or particle jamming, requiring frequent shutdowns for cleaning and resulting in low production efficiency. Existing anti-clogging solutions mainly include mechanical vibration (such as cam-driven screen shaking), scraper friction against the screen, and airflow backflushing. While these can provide some anti-clogging effect, the vibration structure is simple, relying solely on the screen's own vibration, resulting in limited cleaning effectiveness and poor adaptability to sticky materials. Furthermore, the direct friction between the scraper and the screen easily causes wear, requiring frequent component replacement. Additionally, the lack of intelligent control prevents dynamic adjustment of the cleaning mode based on the degree of clogging, leading to energy waste or incomplete cleaning. Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model provides a self-cleaning anti-clogging crusher that integrates multiple anti-clogging mechanisms and can detect clogging conditions in real time. Based on the clogging situation, it can take corresponding anti-clogging measures to reduce the clogging rate and energy consumption.

[0004] This utility model is achieved through the following technical solution:

[0005] This utility model provides a self-cleaning, anti-clogging crusher, comprising: a crushing chamber with a crushing cavity; a crushing blade assembly installed in the crushing chamber for crushing materials input into the crushing cavity; a screen installed in the crushing chamber and located between the lower end of the crushing blade assembly and the discharge end of the crushing cavity; a vibration mechanism connected to the screen for driving vibration; a scraping mechanism installed on one side of the screen for reciprocating movement relative to the screen; a blowing mechanism installed on the lower side of the screen for blowing compressed gas toward the screen; a detection component installed in the crushing chamber for detecting the clogging status of the screen; and a controller connected to the vibration mechanism, the scraping mechanism, the blowing mechanism, and the detection component for controlling at least one of the vibration mechanism, the scraping mechanism, and the blowing mechanism based on feedback information from the detection component.

[0006] The self-cleaning anti-clogging crusher provided by this utility model includes a crushing chamber, a screen, a vibration mechanism, a scraping mechanism, a blowing mechanism, a detection component, and a controller. The vibration mechanism can drive the screen to vibrate, the scraping mechanism can reciprocate relative to the screen, the blowing mechanism can blow compressed gas toward the screen, and the detection component can detect the clogging status of the screen. At the same time, the controller is connected to the vibration mechanism, the scraping mechanism, the blowing mechanism, and the detection component. Thus, the controller controls at least one of the corresponding vibration mechanism, scraping mechanism, and blowing mechanism to operate according to the feedback information from the detection component, so as to clean the screen and reduce the clogging rate of the crusher.

[0007] The controller controls at least one of the vibration, scraping, and blowing mechanisms based on feedback from the detection components, integrating vibration, scraping, and airflow backflushing into a single device. This solves the limitations of a single cleaning mode and enables adaptive switching of cleaning modes, making it more energy-efficient than timed cleaning solutions.

[0008] In summary, this utility model integrates multiple anti-clogging mechanisms and can detect clogging in real time. Based on the clogging situation, corresponding anti-clogging measures can be taken to reduce the clogging rate and energy consumption.

[0009] In an optional embodiment of this application, the crushing box is provided with a feeding hopper, and the discharge end of the feeding hopper is connected to the working space of the crushing blade assembly.

[0011] In an optional embodiment of this application, the sieve mesh has an hourglass-shaped structure.

[0012] In an optional embodiment of this application, the surface of the screen is covered with a polyurethane layer.

[0013] In an optional embodiment of this application, the vibration mechanism includes: a polarization component, which is connected to the screen and can drive the screen to move along its own width direction; and a reset spring, which has a force between the crushing box and the screen and can push the screen against the polarization component.

[0014] In an optional embodiment of this application, the scraping mechanism includes a plurality of scrapers, which are capable of reciprocating along the surface of the screen.

[0015] In an optional embodiment of this application, the scraper is made of an elastic material, and the angle of the scraper relative to the screen is adjustable.

[0031] Example

[0032] Combination Figures 1-3This embodiment provides a self-cleaning, anti-clogging crusher, comprising: a crushing chamber 1 with a crushing cavity 2; a crushing blade assembly installed inside the crushing chamber 1, capable of crushing materials input into the crushing cavity 2; a screen 3 installed inside the crushing chamber 1, located between the lower end of the crushing blade assembly and the discharge end of the crushing cavity 2; a vibration mechanism connected to the screen 3, capable of driving the screen 3 to vibrate; a scraping mechanism installed on one side of the screen 3, capable of reciprocating relative to the screen 3; a blowing mechanism 4 installed on the lower side of the screen 3, capable of blowing compressed gas toward the screen 3; a detection component installed inside the crushing chamber 1, capable of detecting the clogging status of the screen 3; and a controller connected to the vibration mechanism, the scraping mechanism, the blowing mechanism 4, and the detection component, capable of controlling the operation of at least one of the vibration mechanism, the scraping mechanism, and the blowing mechanism 4 according to the feedback information from the detection component.

[0033] Continue to combine Figure 1 and Figure 2 The crushing box 1 is provided with a feeding hopper 5. The discharge end of the feeding hopper 5 is connected to the working space of the crushing blade assembly, so that the material can be fed into the working space of the crushing blade assembly through the feeding hopper 5 and crushed by the crushing blade assembly.

[0034] Specifically, the crushing blade assembly includes: a fixed disk 6 with a feeding channel in the middle, the feeding channel being connected to the discharge end of the feeding hopper 5; a crushing turntable 7, adapted to the fixed disk 6 and positioned directly opposite the fixed disk 6; and a crushing motor 8, which is connected to the crushing turntable 7 and can drive the crushing turntable 7 to rotate around its own axis. Both the fixed disk 6 and the crushing turntable 7 are provided with multiple crushing blades arranged alternately, and the crushing blades on the fixed disk 6 are located between the crushing blades on the crushing assembly to ensure that the crushing blade assembly can crush various materials.

[0035] Combination Figure 4 The screen mesh 3 has an hourglass-shaped aperture 9, meaning the aperture 9 is narrow in the middle and wide at both ends. This allows the aperture 9 to screen out materials while ensuring sufficient space for material movement at both ends of the aperture 9, reducing the probability of particle jamming. Generally, the surface of the screen mesh 3 is covered with a polyurethane layer to ensure sufficient wear resistance, thereby extending the service life of the screen mesh 3.

[0036] Combined again Figure 2 and Figure 3The vibration mechanism includes: a polarization component 10, which is connected to the screen 3 and can drive the screen 3 to move along its own width direction; and a reset spring 11, whose force is between the crushing box 1 and the screen 3 and can push the screen 3 against the polarization component 10.

[0037] Generally, the polarization component 10 includes a polarization motor and a cam structure. The cam mechanism is mounted on the output shaft of the polarization motor and rotates around the output shaft axis driven by the polarization motor. A lever is provided on one side of the cam. The lever is vertically positioned, with its lower end fixedly connected to the cam and its upper end abutting against one side of the screen 3. During the rotation of the cam, the lever alternately pushes the screen 3 horizontally. The screen 3 is pressed against the lever under the action of the return spring 11. As the lever rotates, the return spring 11 drives the screen 3 to reset or store energy, thereby making the screen 3 rotate at a set frequency and preventing material from accumulating on the screen 3.

[0038] It is understood that the scraping mechanism includes multiple scraper blades 12, which are capable of reciprocating along the surface of the screen 3. Typically, the scraper blades 12 are driven to move linearly by a linear drive assembly, such as an electric actuator, a cylinder, or a reciprocating mechanism such as a rack and pinion mechanism or a crank-rocker mechanism, so that the scraper blades 12 can scrape off the material adhering to the screen 3 and can adapt to materials of different properties.

[0039] In this embodiment, the scraper 12 is made of an elastic material, such as elastic plastic, and the angle of the scraper 12 relative to the screen 3 is adjustable, for example, by being mounted on the moving part of the linear drive assembly via a screw, thereby enabling the scraper 12 to be tightly attached to the screen 3.

[0040] Based on this, the detection component includes a camera 14, the lens of which is positioned facing the screen 3 to capture an image of the surface of the screen 3, and to identify whether the screen 3 is clogged through the image (existing technology).

[0041] It should be noted that the purging mechanism 4 should include a nozzle, which is connected to a compressed air source line during use and is capable of pulse-type air jetting to periodically spray compressed air through the screen holes 9 to remove stuck particles. In this embodiment, the nozzle is installed pointing towards the lower end face of the screen 3, and its jetting angle is adjustable.

[0042] In summary, the self-cleaning anti-clogging crusher provided in this embodiment includes a crushing chamber 1, a screen 3, a vibration mechanism, a scraping mechanism, a blowing mechanism 4, a detection component, and a controller. The vibration mechanism can drive the screen 3 to vibrate, the scraping mechanism can reciprocate relative to the screen 3, the blowing mechanism 4 can blow compressed gas toward the screen 3, and the detection component can detect the clogging status of the screen 3. At the same time, the controller is connected to the vibration mechanism, the scraping mechanism, the blowing mechanism 4, and the detection component. Thus, based on the feedback information from the detection component, the controller controls at least one of the corresponding vibration mechanism, scraping mechanism, and blowing mechanism 4 to clean the screen 3, thereby reducing the clogging rate of the crusher.

[0043] Specifically, during material crushing, the material enters the crushing chamber through the feed hopper 5, and the crushing motor 8 drives the crushing disc 7 to rotate and crush the material. After crushing, the material falls onto the screen 3, where larger particles are removed and allowed to continue crushing. Under normal conditions, the deflection component works continuously to ensure that the material passes through the screen 3. When the detection component detects that the screen 3 is blocked, the control module controls the scraping mechanism to work for directional cleaning. If the blockage is severe, the blowing mechanism 4 is simultaneously controlled to pulse and spray at a pressure of 0.5-1 MPa, which, in conjunction with the scraping, removes stubborn adhering materials and powerfully cleans the screen 3.

[0044] The controller controls at least one of the vibration mechanism, scraping mechanism and blowing mechanism 4 according to the feedback information of the detection component, so as to integrate vibration, scraping and airflow backflow into a single device, thereby solving the limitation of a single cleaning mode. Furthermore, it achieves adaptive switching of cleaning modes, which is more energy-efficient than timed cleaning solutions (saving more than 30% of energy).

[0045] In summary, this embodiment integrates multiple anti-clogging mechanisms and can detect clogging in real time. Based on the clogging status, appropriate anti-clogging measures are implemented to reduce the clogging rate and energy consumption. Comparative testing shows that this device reduces the clogging rate of screen 3 by 80% and cleaning energy consumption by 40% when crushing high-moisture materials. It is suitable for pharmaceutical raw materials, chemical powders, and other applications, and has broad market prospects.

[0046] The specific embodiments described above further illustrate the purpose, technical solution, and beneficial effects of this utility model. It should be understood that the above description is only a specific embodiment of this utility model and is not intended to limit the scope of protection of this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the scope of protection of this utility model.
