Description

Technical Field

[0001] The embodiments disclosed herein relate to the field of clay sand processing technology, and more specifically, to a dust collector for a clay sand return belt conveyor transfer point. Background Technology

[0002] In the foundry industry, clay sand is a commonly used molding material. During the recycling of clay sand, a large amount of dust is generated at the sand return conveyor belt transfer point. If this dust is not treated, it will cause serious harm to the working environment and workers' health.

[0003] On the one hand, dust will permeate the air in the workshop, reduce visibility, affect workers' vision, increase the risk of operational errors, and may lead to production accidents. On the other hand, long-term inhalation of this dust will damage workers' respiratory system, causing occupational diseases such as pneumoconiosis, which seriously affects workers' health.

[0004] Furthermore, with increasingly stringent environmental protection requirements, foundry enterprises need to take effective dust removal measures to reduce dust emissions in order to meet environmental standards. Traditional dust removal equipment has some limitations in its application at the clay sand return conveyor belt transfer point, such as low dust removal efficiency, poor equipment stability, and difficulty in adapting to complex working environments. Therefore, it is necessary to develop a high-efficiency dust collector specifically for the clay sand return conveyor belt transfer point to solve the dust pollution problem and protect workers' health and the environment. Utility Model Content

[0005] To overcome the above-mentioned defects, the embodiments of this disclosure provide a dust collector for the clay sand return conveyor belt transfer point, which solves the technical problem that in the prior art, dust will diffuse in the workshop air, reduce the visibility of the workshop, affect the operator's line of sight, increase the risk of operational errors, and may lead to production accidents. Long-term inhalation of this dust will damage the worker's respiratory system and cause occupational diseases such as pneumoconiosis, seriously affecting the worker's health.

[0006] According to one aspect, at least one embodiment of this disclosure provides a dust collector for a clay sand return conveyor belt transfer point, comprising:

[0007] A support frame, on which a dust collection box is provided;

[0008] A dust collection and exhaust system is installed inside the dust collection box;

[0009] A support adjustment assembly is disposed on the support frame;

[0010] The dust removal and ventilation assembly includes an exhaust hood disposed on the lower end face of the dust collection box. An air inlet is provided between the exhaust hood and the dust collection box. An air outlet is provided on the side wall of the dust collection box. An exhaust fan is provided on the air outlet. A drive motor is provided on the side wall of the dust collection box. A drive rod is provided at the output end of the drive motor. The drive rod is disposed inside the dust collection box. A drive bevel gear is provided on the drive rod. A driven rod is provided on the exhaust fan. A driven bevel gear is provided at one end of the driven rod. The drive bevel gear and the driven bevel gear mesh with each other.

[0011] As a further technical solution, a limiting sleeve is fitted on the drive rod, and a limiting frame is provided on the side wall of the limiting sleeve. The limiting frame is fixedly connected to the inner side wall of the dust collector, and the limiting sleeve and the drive rod are fitted together by a bearing.

[0012] As a further technical solution, the support adjustment assembly includes a support frame, the upper end face of which is provided with an insertion groove, the bottom of which is provided with an insertion strip, the insertion strip being inserted into the insertion groove, and the side wall of the support frame being provided with a drive bolt, one end of which is inserted into the insertion groove and contacts the insertion strip.

[0013] As a further technical solution, the width of the support frame matches that of the support stand, and the lower end face of the support stand is provided with a force-bearing area increasing plate.

[0014] As a further technical solution, the dust collection box is equipped with an isolation plate inside, which separates the drive rod to form an independent space.

[0015] As a further technical solution, one end of the drive rod passes through the isolation plate, the isolation plate and the driven rod are connected by a bearing, and the isolation plate and the driven rod are sealed together.

[0016] As a further technical solution, the number of air inlets is several, and the multiple air inlets are arranged in a straight line on the lower end face of the dust collector, and the number of air inlets is the same as the number of air outlets.

[0017] As a further technical solution, a filter bag is installed on the side wall of the dust collection box at the air outlet.

[0018] The beneficial effects of the embodiments disclosed herein are as follows:

[0019] 1. In this disclosure, a drive motor drives a drive rod, which in turn drives the exhaust fan through the meshing transmission of a drive bevel gear and a driven bevel gear. This creates a negative pressure inside the dust collector, effectively collecting dust generated at the clay sand return belt transfer point. The numerous air inlets, arranged in a straight line, can evenly draw in dust-laden air. Combined with the filter bag at the air outlet, this achieves efficient dust filtration and purification, ensuring that the discharged air meets environmental protection standards and reducing dust pollution to the environment.

[0020] 2. In this disclosure, the support adjustment assembly can adjust the height of the support frame through the drive bolts, so that the dust collector can adapt to different working scenarios and equipment layouts. At the same time, the isolation plate in the dust collection box separates the drive rod to form an independent space, preventing dust-laden air from entering and affecting the drive components, ensuring the stable operation of the equipment, extending the service life of the equipment, and reducing maintenance costs.

[0034] like Figures 1-5 As shown, it illustrates a dust collector for a clay sand return conveyor belt transfer point according to this disclosure, comprising:

[0035] Support frame 1, on which a dust collection box 2 is installed;

[0036] Dust removal and exhaust assembly 3 is installed inside the dust collection box 2;

[0037] Support adjustment component 4 is mounted on support frame 1;

[0038] The dust collection and ventilation assembly 3 includes an exhaust hood 3-1, which is located on the lower end face of the dust collection box 2. An air inlet 3-2 is provided between the exhaust hood 3-1 and the dust collection box 2. An air outlet 3-3 is provided on the side wall of the dust collection box 2. An exhaust fan 3-4 is provided on the air outlet 3-3. A drive motor 3-5 is provided on the side wall of the dust collection box 2. A drive rod 3-6 is provided at the output end of the drive motor 3-5. The drive rod 3-6 is located inside the dust collection box 2. A drive bevel gear 3-7 is provided on the drive rod 3-6. A driven rod 3-8 is provided on the exhaust fan 3-4. A driven bevel gear 3-9 is provided at one end of the driven rod 3-8. The drive bevel gear 3-7 and the driven bevel gear 3-9 mesh with each other.

[0039] The support adjustment assembly 4 includes a support frame 4-1, with an insertion slot 4-2 on the upper surface of the support frame 4-1 and an insertion strip 4-3 on the bottom of the support frame 4-1. The insertion strip 4-3 is inserted into the insertion slot 4-2. A drive bolt 4-4 is provided on the side wall of the support frame 4-1, with one end of the drive bolt 4-4 inserted into the insertion slot 4-2 and in contact with the insertion strip 4-3.

[0040] In some examples, a support frame 1 is first constructed. The support frame 1 must have sufficient strength and stability to support the dust collector 2 and other related components. The dust collector 2 is then securely installed on the support frame 1, ensuring that the connections are firm and reliable to prevent shaking or displacement during operation. The exhaust hood 3-1 is then precisely installed on the lower end face of the dust collector 2, ensuring a good seal between the exhaust hood 3-1 and the air inlet 3-2 of the dust collector 2 to prevent dust leakage. An air outlet 3-3 is installed on the side wall of the dust collector 2, and an exhaust fan 3-4 is installed at the air outlet 3-3. Simultaneously, on the side of the dust collector 2... A drive motor 3-5 is mounted on the wall. The output end of the drive motor 3-5 is securely connected to the drive rod 3-6. The drive rod 3-6 is located inside the dust collector 2. A drive bevel gear 3-7 is mounted on the drive rod 3-6. A driven bevel gear 3-9 is mounted on one end of the driven rod 3-8 of the exhaust fan 3-4. The positions of the drive bevel gear 3-7 and the driven bevel gear 3-9 are adjusted to ensure good meshing. When the drive motor 3-5 is running, it drives the drive bevel gear 3-7 to rotate through the drive rod 3-6, which in turn drives the driven bevel gear 3-9, causing the exhaust fan 3-4 to operate and produce a ventilation effect.

[0041] Install the support frame 4-1 in a suitable position. The upper end face of the support frame 4-1 is provided with an insertion slot 4-2. Install the insertion strip 4-3 at the bottom of the support frame 1, ensuring that the insertion strip 4-3 can be accurately inserted into the insertion slot 4-2. If it is necessary to adjust the height of the dust removal equipment, it can be achieved by rotating the drive bolt 4-4 on the side wall of the support frame 4-1. One end of the drive bolt 4-4 is inserted into the insertion slot 4-2. When the drive bolt 4-4 is rotated, its end will exert a force on the insertion strip 4-3, thereby pushing the support frame 1 to rise or fall, so as to achieve the purpose of adjusting the height.

[0042] like Figures 1-5 As shown, in this embodiment, a limiting sleeve 3-10 is fitted on the drive rod 3-6, and a limiting frame 3-11 is provided on the side wall of the limiting sleeve 3-10. The limiting frame 3-11 is fixedly connected to the inner side wall of the dust collection box 2, and the limiting sleeve 3-10 and the drive rod 3-6 are fitted together by a bearing.

[0043] In some examples, to ensure the stable operation of the drive rod 3-6, a limiting sleeve 3-10 is fitted onto the drive rod 3-6, and a limiting frame 3-11 is installed on the side wall of the limiting sleeve 3-10. The limiting frame 3-11 is fixedly connected to the inner side wall of the dust collector 2. The limiting sleeve 3-10 and the drive rod 3-6 are fitted together by a bearing to reduce friction and ensure the axial position of the drive rod 3-6 is fixed.

[0044] For example, such as Figure 1 As shown, the width of the support frame 1 matches that of the support stand 4-1, and the lower end face of the support stand 4-1 is provided with a force-bearing area increasing plate 5.

[0045] In some examples, the width of the support frame 4-1 needs to match that of the support frame 1 to ensure good support effect. In order to increase the load-bearing area of ​​the lower end face of the support frame 4-1 and prevent it from settling or tilting on the ground, a load-bearing area increasing plate 5 is installed on the lower end face of the support frame 4-1.

[0046] For example, such as Figure 5 As shown, the dust collector 2 is equipped with an isolation plate 6 inside. The isolation plate 6 separates the drive rod 3-6 to form an independent space. One end of the drive rod 3-6 passes through the isolation plate 6. The isolation plate 6 and the driven rod 3-8 are connected by a bearing. The isolation plate 6 and the driven rod 3-8 are sealed and inserted together.

[0047] In some examples, an isolation plate 6 is installed inside the dust collection box 2. The isolation plate 6 separates the drive rod 3-6 to form an independent space. One end of the drive rod 3-6 needs to pass through the isolation plate 6. The isolation plate 6 and the driven rod 3-8 are connected by a bearing. It is necessary to ensure that the isolation plate 6 and the driven rod 3-8 are sealed and plugged in to prevent dust from entering the independent space where the drive rod 3-6 is located and affecting the normal operation of the drive components.

[0048] For example, such as Figure 2 As shown, there are several air inlets 3-2, and multiple air inlets 3-2 are arranged in a straight line on the lower end face of the dust collector 2. The number of air inlets 3-2 is the same as the number of air outlets 3-3.

[0049] In some examples, there are several air inlets 3-2, which are arranged in a straight line on the lower end face of the dust collection box 2, so as to collect dust evenly.

[0050] For example, such as Figure 1 As shown, a filter bag is installed on the side wall of the dust collection box 2 at the air outlet 3-3.

[0051] In some examples, a filter bag is installed on the side wall of the dust collector 2 at the air outlet 3-3. The filter bag can effectively filter out the fine dust particles in the exhaust gas and prevent them from being emitted into the atmosphere and causing pollution.

[0052] In use, the drive motor 3-5 serves as the power source for the entire dust removal and exhaust assembly 3. When the drive motor 3-5 starts, its output end rotates at high speed, and the drive rod 3-6 connected to the output end rotates accordingly. Since the drive rod 3-6 is equipped with a drive bevel gear 3-7, the drive bevel gear 3-7 rotates together with the drive rod 3-6. At the same time, a driven bevel gear 3-9 is installed at one end of the driven rod 3-8 of the exhaust fan 3-4, and the drive bevel gear 3-7 and the driven bevel gear 3-9 mesh with each other. According to the transmission characteristics of bevel gears, the rotation of the drive bevel gear 3-7 will drive the driven bevel gear 3-9 to rotate, thereby causing the driven rod 3-8 to rotate and driving the exhaust fan 3-4 to operate. After the exhaust fan 3-4 starts working, a negative pressure will be formed at the air outlet 3-3, generating a strong suction force.

[0053] Under the powerful suction of the exhaust fan 3-4, the air pressure inside the dust collector 2 drops rapidly, creating a negative pressure environment. At this time, the exhaust hood 3-1 located on the lower end face of the dust collector 2 begins to function. Since the air inlet 3-2 is connected to the outside, under the action of pressure difference, the dust-laden air from the outside will quickly rush into the exhaust hood 3-1 from the air inlet 3-2. There are many air inlets 3-2 arranged in a straight line on the lower end face of the dust collector 2, which allows the clay sand dust raised at the belt transfer point to be collected evenly and effectively. A large amount of dust-laden air enters the interior of the dust collector 2 through the air inlets 3-2.

[0054] After dust-laden air enters the dust collector 2, it first passes through a series of internal structures. A filter bag is installed on the side wall of the dust collector 2 at the air outlet 3-3. When the air is discharged from the air outlet 3-3, it must pass through the filter bag. The filter bag has an extremely fine filter structure, and tiny dust particles cannot pass through the filter and are blocked inside the filter bag. The filtered clean air can pass through the filter smoothly and be discharged into the atmosphere from the air outlet 3-3, thereby purifying the exhaust gas and effectively avoiding dust pollution to the environment.

[0055] The support adjustment assembly 4 provides support and height adjustment for the entire dust collector. The support frame 4-1 engages with the insert strip 4-3 at the bottom of the support frame 1 via the insert slot 4-2, which can stably support the support frame 1 and the dust collector box 2 and other components on it. When the height of the equipment needs to be adjusted, the operator only needs to rotate the drive bolt 4-4 on the side wall of the support frame 4-1. One end of the drive bolt 4-4 is inserted into the insert slot 4-2 and contacts the insert strip 4-3. As the drive bolt 4-4 rotates, its end will apply an upward or downward force to the insert strip 4-3, thereby pushing the support frame 1 and the entire equipment to rise or fall, achieving the purpose of height adjustment to adapt to different working scenario requirements.

[0056] An isolation plate 6 installed inside the dust collector 2 separates the drive rod 3-6 into an independent space. One end of the drive rod 3-6 passes through the isolation plate 6, and the isolation plate 6 is connected to the driven rod 3-8 by a bearing and sealed. This design can effectively prevent dusty air from entering the independent space where the drive rod 3-6 is located. Once dust enters this space, it may adhere to the drive rod 3-6, bevel gears and other transmission components, aggravating component wear, affecting transmission efficiency, and even causing equipment failure. The protection of the isolation plate 6 ensures that the drive components operate stably in a relatively clean environment and extends the service life of the equipment.
