Description

Technical Field

[0001] The present invention relates to the field of dust collectors, and particularly to a dust collector for sand and gravel aggregate processing and its usage method. Background Art

[0002] During the operation process before aggregate screening in sand and gravel factories, a large amount of dust is generated, mainly including the primary crushing workshop, the medium and fine crushing workshops of the weathered material processing system, and the medium and fine crushing workshops of the micro-fine weathered material processing system. In the prior art, a spraying system is usually installed in the above workshops for spraying to reduce dust and lower the temperature.

[0003] For example, the patent with application number 202222684549.X discloses a dust reduction spraying device, including a coal transportation workshop shed. At the top inside the coal transportation workshop shed, there is a spraying and dust reduction component for dust reduction spraying, and at the bottom of the coal transportation workshop shed, there is a dust reduction and recovery component for collecting dust particles. In this utility model, by setting a spraying and dust reduction component and a dust reduction and recovery component inside the coal transportation workshop shed, the spraying and dust reduction component can perform dust reduction treatment on the dust in the coal transportation workshop shed, and the dust reduction and recovery component can recover the coal particles after dust reduction, avoiding waste of resources. Through filtration and collection by the particle filter screen inside the particle collection box, the coal particles after dust reduction can be quickly and effectively recycled. The anti-slip cross plates evenly spaced at the top of the working support base can play a certain anti-slip role, preventing the workers walking back and forth on the top of the working support base from slipping, thus improving the work efficiency of the workers.

[0004] The patent with application number 202022171480.1 discloses a workshop dust reduction and suppression system, including a workshop body. Inside the workshop body, a dust reduction and suppression system is installed. The dust reduction and suppression system is composed of a spraying mechanism, a negative pressure dust suction mechanism, and a pulse dust removal mechanism. A shunt pipe is installed inside the spraying mechanism. In this utility model, a dust removal and suppression system is installed inside the workshop body. The dust removal and suppression system is composed of a spraying mechanism, a negative pressure dust suction mechanism, and a pulse dust removal mechanism. The spraying mechanism reduces the dust in the workshop by spraying, the negative pressure dust suction mechanism removes the dust in the workshop by negative pressure, and the pulse dust removal mechanism removes the dust in the workshop by pulse. Through the combined use of multiple dust removal mechanisms, it is convenient to improve the dust removal and suppression effect of the workshop, thus changing the traditional method of only relying on one mechanism for treatment, and greatly reducing the dust content inside the workshop, providing a good and safe working place for the staff.

[0005] However, when the above spraying equipment and similar equipment are in use, they cannot adjust the spraying water volume according to the dust concentration in the workshop, resulting in poor dust removal effect or waste of water source, and improvement is needed. Summary of the Invention

[0033] External water sources enter the spray pipe 4 through the water supply hose 6 and the water supply connecting pipe 5, so that the spray pipe 4 can continuously spray water for dust reduction.

[0034] Embodiment 3

[0035] As Figures 1-4 shown, in the case where other parts are the same as those in Embodiment 2, the difference between this embodiment and Embodiment 2 is that: the water supply mechanism further includes a blower 9. The air outlet end 8 of the blower 9 is fixedly connected to the left end of the ventilation pipe 11, and the air outlet end 8 of the blower 9 is communicated with the left end of the ventilation pipe 11. The right end of the ventilation pipe 11 is fixedly connected to the side of the water supply connecting pipe 5.

[0036] The water supply mechanism further includes a water volume control component. The water volume control component includes an inner pipe 16. A upper fixing ring 22 is sleeved on the upper end of the inner pipe 16. The inner wall of the upper fixing ring 22 is fixedly connected to the inner pipe 16, and the outer wall of the upper fixing ring 22 is fixedly connected to the inner wall of the water supply connecting pipe 5. A lower fixing ring 24 is sleeved on the lower end of the inner pipe 16. The inner wall of the lower fixing ring 24 is fixedly connected to the inner pipe 16, and the outer wall of the lower fixing ring 24 is fixedly connected to the inner wall of the water supply connecting pipe 5. A water volume adjustment hose 15 is arranged inside the inner pipe 16. The outer wall of the water volume adjustment hose 15 is fixedly connected to the inner wall of the inner pipe 16. A notch 17 is formed at the bottom of the side of the inner pipe 16. A pressing block 28 is arranged on the left side of the notch 17. The pressing block 28 is fixedly connected to the lower end of a pressing plate 27. The middle of the pressing plate 27 is connected to the inner pipe 16 through a hinge 26. The top of the pressing plate 27 is fixedly connected to one end of a third spring 25, and the other end of the third spring 25 is fixedly connected to the inner pipe 16.

[0037] The water supply mechanism further includes a water volume adjustment component. The water volume adjustment component includes a pressing rod 18. The pressing rod 18 penetrates through the side of the water supply connecting pipe 5. The right end of the pressing rod 18 abuts against the upper end of the pressing plate 27. The pressing rod 18 is slidably matched with the water supply connecting pipe 5. The pressing rod 18 is located inside the ventilation pipe 11. A rubber ring 20 is sleeved on the outer side of the pressing rod 18. The rubber ring 20 is fixedly connected to the pressing rod 18, and the outer ring of the rubber ring 20 is fixedly connected to the inner wall of the ventilation pipe 11. A first spring 19 is arranged inside the ventilation pipe 11. The diameter of the left side surface of the first spring 19 is larger than that of the right side surface. The right side of the first spring 19 is fixedly connected to the left end of the pressing rod 18, and the left end of the first spring 19 is fixedly connected to the inner wall of the ventilation pipe 11. A plurality of ventilation holes 7 are formed on the outer side of the ventilation pipe 11. The ventilation holes 7 are located in the middle of the first spring 19. A second spring 21 is sleeved on the right side of the pressing rod 18. The left end of the second spring 21 is fixedly connected to the pressing rod 18, and the right end of the second spring 21 is fixedly connected to the water supply connecting pipe 5.

[0038] The water flow circulates through the water volume adjustment hose inside the water supply connecting pipe 5.

[0039] Start the blower 9. The air inlet end 10 of the blower 9 absorbs the dust-containing air in the workshop, and then blows it into the ventilation pipe 11 through the air outlet end 8. The gaps between the coils of the first spring 19 are relatively small. The air flow blown into the ventilation pipe 11 is discharged through the gaps between the coils of the first spring 19 through the ventilation holes 7. If there is more dust in the air, the dust will partially block the gaps between the coils of the first spring 19, which will cause the air pressure inside the first spring 19 to increase. Under the action of the air pressure, the pressing rod 18 is pushed to move rightward, so that the pressing rod 18 drives the upper end of the pressing plate 27 to move rightward to compress the third spring 25. Thus, the lower end of the pressing plate 27 moves leftward, and the pressing block 28 moves leftward synchronously to relieve the pressure on the water volume adjustment hose 15, so that the water flow through the water volume adjustment hose 15 increases. Thus, more water flows into the spray pipe 4, and further more water is sprayed out from the spray head 13 for dust reduction.

[0040] When the pressure rod 18 moves to the right, it synchronously pulls the first spring 19 to the right, increasing the gap between the coils of the first spring 19, thereby reducing the dust blockage between the coils of the first spring 19, stabilizing the air pressure, and causing the pressure rod 18 to stop moving.

[0041] If the dust in the air decreases, the dust blockage between the coils of the first spring 19 is further reduced, the air pressure inside the first spring 19 decreases, and under the elastic force of the second spring 21 and the third spring 25, the pressure rod 18 moves to the left, the upper end of the pressure plate 27 moves to the left synchronously, the lower end of the pressure plate 27 moves to the right, and the pressing block 28 moves to the right synchronously to press the water volume adjustment hose 15, reducing the water flow through the water volume adjustment hose 15, thereby reducing the water flowing into the spray pipe 4 and further reducing the water sprayed out of the spray head 13.

[0042] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments.
