Description

Technical Field

[0001] This utility model relates to the field of filtration device technology, specifically to a power laboratory fume hood with a filtration system. Background Technology

[0002] The power laboratory involves many aspects of work, including the research and development, testing, and performance evaluation of power equipment. In these experiments, various chemical reagents, insulating materials, and special auxiliary equipment are often used. For example, when studying the aging characteristics of insulating materials for power equipment, specific chemical solvents are needed to simulate chemical corrosion in the actual environment. In high-voltage tests, in order to ensure the safety of experimental equipment and operators, it is necessary to effectively control various gases and dust during the experimental process.

[0003] When using fume hoods with filtration systems in power laboratories, traditional filtration equipment is generally used to filter larger particles such as dust in the air inside the power laboratory. As dust continuously adheres to the filtration device, it affects the effectiveness of the equipment. Utility Model Content

[0004] The purpose of this invention is to provide a power laboratory fume hood with a filtration system to solve the problem mentioned in the background art that traditional filtration equipment is generally used to filter larger particulate matter such as dust in the air inside the power laboratory. As dust is constantly adsorbed on the filtration device, the effect of the equipment is affected.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a power laboratory fume hood with a filtration system, comprising a main body, wherein a driven gear is rotatably connected to the center of the inner top surface of the main body via a fixed short rod, a reciprocating screw is fixedly connected to the center of the bottom of the driven gear, a limit block is fixedly connected to the bottom of the reciprocating screw, a fixed rod is fixedly connected to the bottom of the limit block, and a dust collection scraper is fixedly sleeved on the outer surface of the fixed rod near the bottom edge.

[0006] In a preferred embodiment, a dust collection chamber is fixedly installed at the bottom center of the main body of the device, and the dust collection chamber is rotatably connected to the fixed rod. A dust discharge port is opened at the bottom of the dust collection chamber near one side edge.

[0007] In a preferred embodiment, the top of the dust collection chamber is rotatably connected to a filter cover, and the inner surface of the filter cover is provided with a sloping ramp near the bottom edge.

[0008] In a preferred embodiment, an annular transmission frame is fixedly provided on the inner surface wall of the filter cover near the top edge, and three limiting grooves are equidistantly provided on the inner surface wall of the filter cover near the center along the circumferential direction.

[0009] In a preferred embodiment, the outer surface of the reciprocating lead screw is connected to an annular scraper by a crescent-shaped pin thread. The outer surface of the annular scraper is provided with three limiting sliders at equal intervals along the circumferential direction, and the limiting sliders slide and fit into the limiting groove.

[0010] In a preferred embodiment, a motor is fixedly mounted on the top of the main body of the device, and the output shaft of the motor extends into the interior of the main body of the device. The output shaft of the motor is rotatably connected to a drive gear through a fixed short rod, and the drive gear meshes with the driven gear and the ring transmission frame respectively.

[0011] In a preferred embodiment, fan connection ports are provided on the outer surfaces of both the front and rear sides of the main body of the device near the center.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] This invention, firstly, utilizes a fan connection port to connect to fans and other equipment, facilitating the extraction of air from the power laboratory into the equipment for adsorption by a filter cover. When the filter cover adsorbs excessive dust particles, starting the motor causes the output shaft to drive the drive gear to rotate. Through their meshing relationship, the rotation of the drive gear drives the filter cover to rotate in the same direction via a ring transmission frame, and under the constraint of the limiting slider and limiting groove, it drives the ring scraper to rotate in the same direction. Simultaneously, the rotation of the drive gear drives the driven gear and the reciprocating screw to rotate in opposite directions. The filter is threadedly connected to an annular scraper, and the reciprocating motion of the annular scraper is achieved through a crescent pin and a reciprocating screw. This allows the annular scraper to scrape away the dust particles adsorbed inside the filter cover, which are quickly collected inside the dust collection bin by the inclined slide. As the reciprocating screw rotates in the opposite direction, it can drive the limit block and the fixing rod to rotate synchronously, thereby driving the dust collection scraper to rotate circumferentially. The dust particles collected inside the dust collection bin are continuously scraped towards the dust discharge port, and then discharged uniformly through the dust discharge port. A collection container can be placed below the dust discharge port in advance. This provides an effective solution for the repeated use of the filter cover and improves the performance of the equipment. Attached Figure Description

[0019] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0020] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0021] Please see Figures 1-4 This utility model provides a technical solution: a power laboratory fume hood with a filtration system, including a main body 1. A driven gear 2 is rotatably connected to the center of the top surface of the main body 1 via a fixed short rod. A reciprocating screw 3 is fixedly connected to the center of the bottom of the driven gear 2. A limit block 4 is fixedly connected to the bottom of the reciprocating screw 3. A fixed rod 5 is fixedly connected to the bottom of the limit block 4. A dust collection scraper 6 is fixedly sleeved on the outer surface of the fixed rod 5 near the bottom edge. When the driven gear 2 rotates, it can drive the reciprocating screw 3 and the fixed rod 5 to rotate. The rotation of the fixed rod 5 can synchronously drive the dust collection scraper 6 to rotate circumferentially inside the dust collection chamber 7. The circumferential rotation of the dust collection scraper 6 can scrape the dust collected inside the dust collection chamber 7 towards the dust discharge port 8.

[0022] A dust collection chamber 7 is fixedly installed at the bottom center of the main body 1 of the device, and the dust collection chamber 7 is rotatably connected to the fixed rod 5. The dust collection chamber 7 can collect the dust particles that are scraped off. A dust discharge port 8 is opened at the bottom of the dust collection chamber 7 near one side edge. The dust particles collected inside the dust collection chamber 7 can be discharged uniformly through the dust discharge port 8. The top of the dust collection chamber 7 is rotatably connected to a filter cover 9. The filter cover 9 can adsorb dust particles in the air. A sloping ramp 10 is provided on the inner surface wall of the filter cover 9 near the bottom edge. The sloping ramp 10 can more conveniently collect the dust particles scraped off inside the filter cover 9 inside the dust collection chamber 7.

[0023] A ring-shaped transmission frame 11 is fixedly installed on the inner wall of the filter cover 9 near the top edge. The ring-shaped transmission frame 11 can mesh with the drive gear 16 for transmission. Three equidistant limiting grooves 12 are circumferentially spaced on the inner wall of the filter cover 9 near the center. These grooves provide space for the sliding limit sliders 14. A ring-shaped scraper 13 is threaded onto the outer surface of the reciprocating screw 3 via a crescent-shaped pin. Three equidistant limiting sliders 14 are circumferentially spaced on the outer surface of the ring-shaped scraper 13, and these sliders 14 slide and engage with the limiting grooves 12. A motor 15 is fixedly installed on the top of the main body 1, and the output shaft of the motor 15 extends into the interior of the main body 1. The output shaft of the motor 15 is rotatably connected to the drive gear 16 via a fixed short rod. The drive gear 16 meshes with the driven gear 2 and the ring-shaped transmission frame 11. When the motor 15 is started, the motor 15… The output shaft drives the drive gear 16 to rotate. Through the meshing relationship, when the drive gear 16 rotates, it drives the filter cover 9 to rotate in the same direction through the ring transmission frame 11. Under the restriction of the limit slider 14 and the limit groove 12, it drives the ring scraper 13 to rotate in the same direction. At the same time, the rotation of the drive gear 16 can drive the driven gear 2 and the reciprocating screw 3 to rotate in opposite directions. The reciprocating screw 3 and the ring scraper 13 are connected by threads, and the ring scraper 13 moves up and down through the crescent pin and the reciprocating screw 3. This allows the ring scraper 13 to scrape off the dust particles adsorbed inside the filter cover 9. Fan connection ports 17 are provided on the outer surfaces of the front and rear sides of the main body 1 near the center. The fan connection ports 17 can be used to connect fans and other equipment, so that the air inside the power laboratory can be discharged into the equipment and adsorbed by the filter cover 9.

[0024] Working Principle: When the equipment is in use, the fan connection port 17 can be used to connect to a fan or other equipment, facilitating the exhaust of air from the power laboratory into the equipment for adsorption treatment by the filter cover 9. When the filter cover 9 adsorbs excessive dust particles, the motor 15 is started. Under the action of the output shaft of the motor 15, the drive gear 16 is driven to rotate. Through the meshing relationship, as the drive gear 16 rotates, it drives the filter cover 9 to rotate in the same direction through the annular transmission frame 11. Under the restriction of the limit slider 14 and the limit groove 12, it drives the annular scraper 13 to rotate in the same direction. At the same time, the rotation of the drive gear 16 can drive the driven gear 2 and the reciprocating screw 3 to rotate in opposite directions. The reciprocating screw 3 is threadedly connected to the annular scraper 13, and the annular scraper 13 moves up and down through the crescent pin and the reciprocating screw 3. This allows the annular scraper 13 to scrape off the dust particles adsorbed inside the filter cover 9. With the inclined slide 10, the dust particles are quickly collected inside the dust collection chamber 7. As the reciprocating screw 3 rotates in the opposite direction, it can drive the limit block 4 and the fixing rod 5 to rotate synchronously, thereby driving the dust collection scraper 6 to rotate in a circle. This continuously scrapes the dust particles collected inside the dust collection chamber 7 towards the dust discharge port 8, where the dust particles are discharged uniformly. A collection container can be placed below the dust discharge port 8 in advance. This provides an effective solution for the repeated use of the filter cover 9 and improves the performance of the equipment.

[0025] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
