Abstract
Description
Technical Field
[0001] This utility model belongs to the technical field of sand making equipment, and in particular relates to an effective sand making station for dust prevention and removal. Background Technology
[0002] The function of sand making equipment is to process large stone particles into sand particles of the required size. The stone materials mainly consist of mine rocks such as granite and limestone, as well as tailings crushed stone.
[0003] Sand making machines are fine material crushing equipment, generating a large amount of dust during the crushing process. They are the dust-generating equipment among all crushing equipment. Current equipment mainly uses spraying or mist cannons for dust suppression. This causes stone powder to adhere to the manufactured sand product. For manufactured sand with strict control over powder content, the crushed material needs to be further processed by an air classifier for dust removal. However, the stone powder in the finished product is still attached due to its high moisture content and cannot be removed, resulting in substandard finished products. At the same time, using mist cannons as a dust suppression method increases the humidity of the dust in the environment. This causes the dust with high humidity to easily adhere to the exhaust fans of the heat dissipation equipment, easily causing blockage of the exhaust fan grilles and reducing the efficiency of exhaust heat dissipation. In addition, the increased humidity in the high-dust environment will also cause the air classifier's fan to have increased dust moisture adhering to its inside due to the increased humidity of the dust it draws in, resulting in a significant reduction in the air classifier's efficiency. Utility Model Content
[0004] The purpose of this utility model is to provide an effective dust prevention and removal sand making station to solve the technical problems mentioned in the background art.
[0005] To achieve the above objectives, the present invention adopts the following technical solution:
[0006] An effective dust control and dust removal sand making station includes a main unit. A feeding conveyor is installed at the left end of the main unit, and the right end of the feeding conveyor is connected to the feed inlet of the main unit. A screening machine is fixedly installed at the discharge port of the main unit. A return conveyor is arranged at the front of the main unit, and the right side of the return conveyor is connected to the lower right end of the screening machine. A purifier is arranged on the right side of the main unit. A dust suction pipe is fixedly installed at the front of the purifier, and a powder discharge pipe is fixedly installed at the lower end of the purifier. The lower end of the dust suction pipe is located at the connection between the discharge port of the main unit and the screening machine. The purifier is equipped with a dust removal and purification component.
[0007] Furthermore, a first fully sealed dust cover is fixedly installed at the right end of the feeding conveyor and at the feed inlet of the main unit.
[0008] Furthermore, a second fully sealed dust cover is fixedly installed at the connection between the feed port of the main unit and the screening machine, and the lower end of the dust suction pipe is fixedly connected to the right side of the second fully sealed dust cover.
[0009] Furthermore, the purification component includes a purification chamber disposed at the upper end of the purifier. The purification chamber is connected to a suction pipe. A lift valve is fixedly installed at the upper end of the purification chamber. An exhaust pipe and an air inlet pipe are disposed inside the purifier. The air inlet pipe is located below the exhaust pipe. Two sets of connecting pipes are fixedly installed at the lower end of the air inlet pipe. A filter chamber and a dust removal chamber are respectively disposed at the front and rear ends of the purifier. The filter chamber and the dust removal chamber are connected to the two sets of connecting pipes. A flap valve is disposed in each of the two sets of connecting pipes. A blower pipe is disposed on the upper side of the dust removal chamber.
[0010] Furthermore, a dust cover is fixedly installed on the upper side of the screening machine.
[0011] Furthermore, dust curtains are fixedly installed on both the front and rear sides of the screening machine, and the lower end of the dust curtains is connected to the right end of the return conveyor.
[0012] The advantages of this utility model compared to the prior art are as follows:
[0013] 1. This utility model uses a first fully sealed dust cover and a second fully sealed dust cover on the feeding port and discharging port of the feeding conveyor and screening machine and the main machine to prevent dust from being scattered into the air due to gravity during feeding and discharging.
[0014] 2. This utility model uses a purification component within the purifier to reduce and remove dust from the particles drawn into it, achieving effective dust collection and purification, greatly reducing dust pollution to the environment. The purifier captures the negative pressure formed by dust at the second fully sealed dust cover through a suction pipe, which simultaneously carries the dust from the upper feed inlet of the main unit downwards, thus achieving the effect of absorbing dust from two locations with one dust removal port. Furthermore, it avoids the problem of dust adhering to the finished material in traditional dust removal methods, ensuring the quality of the manufactured sand. This not only improves dust removal efficiency but also prevents dust from clogging and damaging the equipment, extending the service life of the equipment. Attached Figure Description

Detailed Implementation
[0021] To make the objectives, technical solutions, and advantages of this utility model clearer, the following detailed description is provided with reference to the accompanying drawings and preferred embodiments. However, it should be noted that many details listed in the specification are merely to provide the reader with a thorough understanding of one or more aspects of this utility model, and these aspects can be achieved even without these specific details.
[0022] like Figure 1-4 As shown, an effective dust prevention and dust removal sand making station includes a main unit 1. A feeding conveyor 2 is installed at the left end of the main unit 1, and the right end of the feeding conveyor 2 is connected to the feed inlet of the main unit 1. A screening machine 3 is fixedly installed at the discharge port of the main unit 1. A return conveyor 19 is set at the front side of the main unit 1, and the right side of the return conveyor 19 is connected to the lower right side of the screening machine 3. A purifier 6 is set at the right side of the main unit 1. A dust suction pipe 7 is fixedly installed at the front side of the purifier 6, and a powder discharge pipe 8 is fixedly installed at the lower end of the purifier 6. The lower end of the dust suction pipe 7 is located at the connection between the discharge port of the main unit 1 and the screening machine 3. A purification component for dust removal is installed inside the purifier 6.
[0023] During operation, raw materials are fed into the main unit 1 via the feeding conveyor 2 for sand making. The finished sand material falls from the discharge port of the main unit 1 onto the screening machine 3. At the same time, the dust generated during the sand making process of the main unit 1 is sucked into the purifier 6 through the dust suction pipe 7. The dust is then removed by the purification components in the purifier 6, separating large particles from the dust to prevent damage to subsequent equipment. The purified air is discharged through the dust discharge pipe 8, achieving effective dust collection and purification. It can effectively capture and separate large particles from the dust, ensuring that the quality of the discharged air meets environmental protection standards. Its robust and durable design allows it to operate stably for a long time in harsh industrial environments, greatly extending the service life of the equipment.
[0024] The right end of the feeding conveyor 2 is fixedly installed with a first fully sealed dust cover 4 at the feed inlet of the main unit 1.
[0025] During use, when the raw materials are fed into the feeding port of the main unit 1 via the feeding conveyor 2, the first fully sealed dust cover 4 ensures that the feeding process is stable and that dust does not escape everywhere. The design of the first fully sealed dust cover 4 not only enhances the sealing performance of the device, but also effectively reduces the leakage of dust during the feeding process, further improving the dust prevention effect.
[0026] A second fully sealed dust cover 5 is fixedly installed at the connection between the feed port of the main unit 1 and the screening machine 3, and the lower end of the dust suction pipe 7 is fixedly connected to the right side of the second fully sealed dust cover 5.
[0027] During use, when the finished material after sand making falls from the discharge port of the main unit 1 onto the screening machine 3, the sealing of the connection is further enhanced by the second fully sealed dust cover 5, preventing the dust from escaping during the discharge process. At the same time, the dust suction pipe 7 is stably fixed near the discharge port of the main unit 1 by the second fully sealed dust cover 5, ensuring that the dust can be effectively sucked into the purifier 6 for purification.
[0028] The purification assembly includes a purification chamber 11, which is located at the upper end of the purifier 6 and connected to a suction pipe 7. A lift valve 12 is fixedly installed at the upper end of the purification chamber 11. An exhaust pipe 13 and an air inlet pipe 14 are installed inside the purifier 6. The air inlet pipe 14 is located below the exhaust pipe 13. Two sets of connecting pipes 15 are fixedly installed at the lower end of the air inlet pipe 14. A filter chamber 16 and a dust removal chamber 17 are respectively installed at the front and rear ends of the purifier 6. The filter chamber 16 and the dust removal chamber 17 are connected to the two sets of connecting pipes 15. A flap valve is installed in each of the two sets of connecting pipes 15. A blowpipe 18 is installed on the upper side of the dust removal chamber 17.
[0029] During use, dust enters the purifier 6 through the suction pipe 7. The dust then passes through the exhaust pipe 13, the intake pipe 14, the connecting pipe 15, the filter chamber 16, and the dust removal chamber 17 to purify and clean the intake air, providing a necessary channel for the smooth flow of dust and further improving the dust removal efficiency.
[0030] A dust cover 9 is fixedly installed on the upper side of the screening machine 3.
[0031] During use, the sand and gravel conveyed on the screening machine 3 are protected by the dust cover 9, and the dust contained in the sand and gravel on the screening machine 3 is dispersed in the air, further reducing the pollution of dust to the environment.
[0032] Dust curtains 10 are fixedly installed on both the front and rear sides of the screening machine 3, and the lower end of the dust curtains 10 is connected to the right end of the return conveyor 19.
[0033] During use, the dust curtain 10 further enhances the sealing of the screening machine 3 during sand and gravel screening, preventing dust from flying everywhere when the return conveyor 19 is used for secondary crushing after screening.
[0034] Working principle: Raw materials enter the main unit 1 through the feeding conveyor 2 for sand making. When the feeding conveyor 2 feeds the raw materials into the upper feeding port of the main unit 1, it is sealed by the first fully sealed dust cover 4 to prevent dust from scattering during feeding. After the main unit 1 crushes the raw materials, they fall onto the screening machine 3 through the lower feeding port, and are then sealed by the second fully sealed dust cover 5. The dust extraction motor on the purifier 6 uses the dust extraction pipe 7 to suck up the sand and gravel. Dust generated during the material feeding process is drawn into the purifier 6. Sand and gravel are screened by the screening machine 3 and protected by the dust cover 9 and the dust curtain 10 to prevent dust from scattering during the screening process. When the dust enters the purifier 6, it is sent into the filter chamber 16 through the purification chamber 11, the exhaust pipe 13 and the connecting pipe 15. The dust is filtered in the filter chamber 16. The filtered air is purified through the dust removal chamber 17 and the blow pipe 18. The dust filtered through the filter chamber 16 is discharged through the dust discharge pipe 8.
[0035] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
