Description

Technical Field

[0001] This utility model relates to the field of carbonized rice husk screening technology, and more specifically, to a screening device for carbonized rice husk processing. Background Technology

[0002] Carbonized rice husks refer to the charred material formed by heating rice husks to below their ignition point, causing incomplete combustion. They are lightweight and have low thermal conductivity, making them suitable for use as thermal insulation materials in industrial production, such as steel and iron production. In agriculture, they can be used for cultivating vegetables, flowers, seedlings, fruit trees, and other crops, as well as for soil improvement. In daily life, they can be used as a clean energy source for starting fires and heating. However, during carbonization, rice husks easily clump together, forming husk blocks. Existing screening devices for carbonized rice husk processing can only screen the carbonized husks, making it difficult to break up the clumps. This requires manual selection and further crushing by workers, increasing labor costs. Therefore, we propose a screening device for carbonized rice husk processing.

[0003] To address the above issues, application number 202320433071.5, entitled "A Screening Device for Carbonized Rice Husk Processing," describes a device comprising a base plate with a receiving frame at the center of its upper surface. A screening device is mounted on the top of the base plate, and a motor is mounted on top of the screening device. The screening device includes two support plates, with two sliders at the center of the two support plates. A long column is positioned at the center of the two sliders, and a vibrating cylinder is mounted outside the long column. When the motor is turned on, its shaft rotates via a short plate, causing the short column to rotate. The short column moves the long plate downwards, which in turn causes the long plate to move a connecting column vertically up and down. The connecting column then moves the long column up and down, causing the vibrating cylinder to move up and down. The vibrating cylinder rotates the long column, and the long column, while rotating the vibrating cylinder, also moves up and down. This causes the rice husk pieces adhering inside the vibrating cylinder to collide with the protective shell and the vibrating cylinder, breaking the rice husk pieces. This eliminates the need for manual sorting and further crushing by workers, saving costs.

[0004] Although the device has many beneficial effects, the following problems still exist: The device has significant advantages in rice husk processing. It can effectively crush rice husk blocks, thereby avoiding the tedious process of manual selection and re-crushing by workers, which greatly saves operating costs. However, in the process of using the vibrating cylinder for screening, there is a problem that cannot be ignored. The small holes on the outer wall of the vibrating cylinder are often blocked by rice husks or their debris. The device lacks an effective automatic cleaning device. If this situation continues for a long time, it will have an extremely adverse effect on the screening effect, and may even lead to a decrease in the efficiency and quality of the entire screening process.

[0005] Secondly, during the vibratory screening of carbonized rice husks, the carbonized rice husks often generate a lot of dust due to the vibrating screen. This dust not only easily affects the working environment of personnel, but also makes the subsequent collection and cleaning quite cumbersome, thus bringing many inconveniences to actual use.

[0006] In view of this, we propose a screening device for carbonized rice husk processing. Utility Model Content

[0007] 1. Technical problems to be solved

[0008] The purpose of this invention is to provide a screening device for carbonized rice husk processing, so as to solve the problems mentioned in the background art of easy clogging of the screening barrel and the easy generation of a large amount of dust during screening.

[0009] 2. Technical Solution

[0010] A screening device for carbonized rice husk processing includes a fixed base, a spring and a vibration motor at the bottom of the fixed base, a support column at the end of a plurality of springs, a fixed box at the top of the fixed base, a screening assembly rotatably connected inside the fixed box, the screening assembly including a screening bucket, a gear motor and an ultrasonic generator at the side wall of the fixed box, a gear connected to the output end of the gear motor, a cleaning assembly at the inner wall of the fixed box including a mounting frame, a fan and a dust collection box at the top of the fixed box, and a dust collection box at the outer wall of the fixed box.

[0011] Preferably, the bottom of the inner cavity of the fixed box is inclined, and a discharge port is provided on the rear outer wall of the fixed box.

[0012] Preferably, one end of the screening barrel has a feed inlet, and the other end of the screening barrel is connected to a toothed ring that meshes with a gear. The outer wall of the toothed ring is connected to a sealing door by a pin.

[0013] Preferably, the inner wall of the mounting frame is provided with an ultrasonic vibrating rod electrically connected to the ultrasonic generator, and the outer wall of the mounting frame is provided with an air blowing box.

[0014] Preferably, the top of the air-blowing box is provided with an air supply pipe, and the ends of the plurality of air supply pipes are connected to the output end of the blower.

[0015] Preferably, a vacuum pump is provided on the top of the vacuum box, the output end of the vacuum pump is connected to a vacuum pipe, and the end of the vacuum pipe is connected to the side wall of the dust collection box.

[0016] Preferably, a sliding door is connected to the front of the dust collection box by a pin, and an intercepting net is snapped onto the outer wall of the sliding door. An electric push rod is provided on the top of the dust collection box, and a pressure plate is connected to the output end of the electric push rod.

[0017] 3. Beneficial effects

[0018] Compared with the prior art, the advantages of this utility model are as follows: In actual use, carbonized rice husks can be put into the screening barrel through the feed inlet. Then, the rotation of the gear motor drives the screening barrel to rotate. At this time, the screening barrel can slowly rotate and screen the material inside. During screening, since the screening barrel is in a slow rotation state, the ultrasonic vibrator inside the mounting frame can be activated. The force generated by the ultrasonic vibration is applied to the outer circumference of the screening barrel. At the same time, the fan is activated to generate a certain airflow. The airflow is released through the air blowing box to blow the screening holes on the outer wall of the screening barrel. Through this composite cleaning method, the screening barrel can be thoroughly cleaned while screening, effectively reducing the clogging of the screening holes and thus affecting the subsequent screening.

[0019] Secondly, the dust generated during the screening process can be sucked up by a dust pump and then transferred to the dust collection box through a dust suction pipe. This can greatly reduce dust pollution. After the dust is sucked into the dust collection box, the pressure plate can be lowered by an electric push rod to compress the collected dust. This not only makes it easier to collect later, but also avoids dust from being stirred up during the collection process. Furthermore, the compressed dust blocks are more convenient for personnel to store and transport later, significantly improving its practicality. Attached Figure Description

[0028] Please see Figure 1-4 This utility model provides a technical solution:

[0029] A screening device for processing carbonized rice husks includes a fixed base 100, and a spring 111 and a vibration motor 120 are provided at the bottom of the fixed base 100.

[0030] In some embodiments, the vibration motor 120 can facilitate the vibration crushing and screening of carbonized rice husks. When the vibration screen is in use, the gear motor 230 stops rotating, and when the gear motor 230 drives the screen bucket 220 to rotate, the vibration motor 120 stops to avoid conflict between the two and affect their normal operation. Alternatively, the vibration motor 120 can be used without the need for the required configuration.

[0031] Multiple springs 111 are connected to support columns 110 at their ends. A fixed box 200 is provided on the top of the fixed base 100. A screening assembly is rotatably connected inside the fixed box 200. The screening assembly includes a screening bucket 220. A gear motor 230 and an ultrasonic generator 240 are provided on the side wall of the fixed box 200.

[0032] In some embodiments, the ultrasonic generator 240 converts mains power into a high-frequency AC signal that matches the ultrasonic transducer. It mainly consists of a power supply, an inverter circuit, a control circuit, and a display circuit. The power supply provides energy, the inverter circuit converts DC power into high-frequency AC power, the control circuit adjusts the frequency, power, and other parameters of the output signal to meet different application requirements, and the display circuit displays the generator's operating status and parameters. The ultrasonic vibrator 251 mainly consists of a transducer, an amplitude transformer, and a tool head. The transducer is the core component that converts electrical energy into mechanical vibration energy and is typically made of piezoelectric ceramic material. When high-frequency AC power is applied to the transducer, the piezoelectric ceramic vibrates at high frequency. The amplitude transformer amplifies the vibration amplitude generated by the transducer to obtain a stronger vibration effect. The tool head directly contacts the object being processed, transferring vibration energy to the object to achieve various processing or handling operations. It facilitates the vibration cleaning of impurities in the screen holes, reducing clogging.

[0033] The output end of the gear motor 230 is connected to a gear, and the inner wall of the fixed box 200 is also provided with a cleaning component, which includes a mounting bracket 250. The top of the fixed box 200 is provided with a fan 260 and a dust collection box 270, and the outer wall of the fixed box 200 is provided with a dust collection box 300.

[0034] Specifically, the bottom of the inner cavity of the fixed box 200 is inclined, and the outer wall at the rear of the fixed box 200 is provided with a discharge port 210 to facilitate the discharge of the dried carbonized rice husks.

[0035] Furthermore, the screening barrel 220 has a feed inlet 221 at one end and a toothed ring 222 that meshes with a gear at the other end. The outer wall of the toothed ring 222 is connected to a sealing door 223 by a pin.

[0036] In some embodiments, the feed inlet 221 is also provided with a sealing door 223 to facilitate sealing both ends of the screening bucket 220 and prevent dust from scattering during screening. The screening bucket 220 is slightly tilted.

[0037] Furthermore, the inner wall of the mounting frame 250 is provided with an ultrasonic vibrating rod 251 electrically connected to the ultrasonic generator 240, and the outer wall of the mounting frame 250 is provided with an air blowing box 252, which facilitates cleaning of the screen bucket 220 by using airflow in conjunction with vibration.

[0038] Furthermore, the top of the air box 252 is equipped with an air supply pipe, and the ends of multiple air supply pipes are connected to the output end of the blower 260.

[0039] It is worth noting that a dust pump 280 is installed on the top of the dust collection box 270. The output end of the dust pump 280 is connected to a dust suction pipe, and the end of the dust suction pipe is connected to the side wall of the dust collection box 300, which facilitates the collection of dust during material screening.

[0040] It is worth noting that a sliding door 310 is connected to the front of the dust collection box 300 by a pin, and an intercepting net 320 is snapped onto the outer wall of the sliding door 310. An electric push rod 330 is installed on the top of the dust collection box 300, and a pressure plate 340 is connected to the output end of the electric push rod 330 to facilitate the compaction of the collected dust, which is convenient for later transportation or storage.

[0041] In some embodiments, the device can be powered by an external conventional power source. The device can be controlled by an external controller; all of the above are prior art.

[0042] In addition, the circuits, electronic components and modules involved in this utility model are all existing technologies, which can be fully implemented by those skilled in the art, and need not be elaborated upon. The content protected by this utility model does not involve any improvement to the internal structure and method.

[0043] Working Principle: In actual use, carbonized rice husks can be fed into the screening barrel 220 through the feed inlet 221. Then, the rotation of the gear motor 230 drives the screening barrel 220 to rotate, allowing it to slowly rotate and screen the material. During screening, because the screening barrel 220 is rotating slowly, the ultrasonic vibrator 251 inside the mounting frame 250 can be activated. The force generated by the ultrasonic vibration is applied to the outer circumference of the screening barrel 220. Simultaneously, the blower 260 is activated to generate airflow, which is released through the air blowing box to blow air through the screening holes on the outer wall of the screening barrel 220. Through this combined cleaning method, the material can be effectively cleaned. While screening materials, the screening hopper is thoroughly cleaned, effectively reducing the risk of clogging the screening holes and affecting subsequent screening. Dust generated during screening can be collected by the dust pump 280 and transferred to the dust collection box 300 via the suction pipe, further reducing dust pollution. Once the dust is sucked into the dust collection box 300, the electric push rod 330 lowers the pressure plate 340 to compress the collected dust. This not only facilitates subsequent collection but also prevents dust from being stirred up during collection. Furthermore, the compressed dust blocks are easier for personnel to store and transport later, significantly improving its practicality.

[0044] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
