Cement tank for dust removal

Abstract

This utility model provides a dust-reducing cement silo, including a cement silo with a telescopic sleeve at the discharge port and a moving device at the end of the sleeve. The moving device can adjust the height of the discharge port of the sleeve to match the height of the inlet of the loading equipment, thereby reducing the dust generated when the height difference between the discharge point and the receiving point is too large during the discharge of cement silo. By providing a telescopic sleeve at the discharge port of the cement silo, the drop difference between the discharge point and the receiving point is reduced, which can effectively reduce the splashing of cement when it falls during the unloading process, thereby reducing the purpose of dust reduction. It can also provide wind protection and shielding, reducing the dust run-out caused by wind when unloading without the sleeve.

Description

Technical Field

[0001] This utility model relates to the field of building construction technology, and in particular to a dust removal and dust reduction cement tank. Background Technology

[0002] During the construction of cement-soil mixing piles at the construction site, excessive dust was generated from the cement silos, which did not meet the existing construction requirements. The dust raised by the cement silos polluted the atmosphere and harmed human health. Dust floating in the atmosphere is also an important cause of smog. When people inhale dust, it can lead to occupational diseases such as pneumoconiosis and silicosis.

[0003] Currently, cement silos at construction sites are generally fed directly into the equipment through the discharge port, which generates a lot of dust during the feeding process. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a dust-reducing cement silo to solve the problem of excessive dust generation during cement silo discharge.

[0005] To solve the above-mentioned technical problems, this utility model provides a dust-reducing cement silo, including a cement silo, a telescopic sleeve provided at the cement silo discharge port, and a moving device provided at the end of the sleeve. The moving device can adjust the height of the sleeve discharge port, thereby reducing the dust generated when the height difference between the discharge point and the receiving point is too large when the cement silo is discharging.

[0006] In a preferred embodiment, the moving device includes an electric actuator, a clamp disposed at the end of the sleeve, and an extension rod of the electric actuator connected to the clamp.

[0007] In the preferred embodiment, the clamp includes a left clamp with an arc and a right clamp with an arc, a sleeve is set between the left clamp and the right clamp, the left clamp and the right clamp are connected by screws, a connecting handle is provided on the left clamp, and an electric actuator is connected to the connecting handle.

[0008] In the preferred embodiment, a vent is provided on the cement silo, and a sedimentation tank is connected to the vent via a pipe.

[0009] In a preferred embodiment, a closed chamber with a switchable door is provided between the cement silo discharge port and the sleeve. The discharge port is connected to the top of the closed chamber via a feeding pipe, and the sleeve is connected to the end of the feeding pipe. The bottom of the electric actuator is located inside the lower part of the closed chamber. The sedimentation tank is located inside the closed chamber, and a dust collection device is also provided inside the closed chamber.

[0010] In a preferred embodiment, the dust collection device includes a dust collection hood fixedly installed on the top of the enclosed room, an axial flow exhaust fan is installed inside the dust collection hood, and the outlet of the axial flow exhaust fan is connected to the sedimentation tank through a pipe.

[0011] In the preferred embodiment, a roller shutter door is provided at the opening of the enclosed room.

[0012] The beneficial effects of this utility model are as follows: Because this utility model is equipped with a dust-reducing cement silo, and by providing a retractable sleeve at the cement silo discharge port, the drop difference between the discharge point and the receiving point is reduced, which can effectively reduce the splashing of cement when it falls during the unloading process, thereby reducing dust. It can also provide wind protection and reduce the dust run-off caused by wind when unloading without the sleeve. Attached Figure Description

Detailed Implementation

[0018] Please see Figure 1-3 As shown, this application provides a technical solution: a dust-reducing cement silo, including a cement silo 11, a telescopic sleeve 12 is provided at the discharge port 111 of the cement silo 11, and a moving device 2 is provided at the end of the sleeve 12. The moving device 2 can adjust the height of the discharge port of the sleeve 12 to match the height of the inlet of the loading equipment, thereby reducing the dust generated when the height difference between the discharge point and the receiving point is too large when the cement silo 11 is discharging.

[0019] The sleeve 12 can be a corrugated telescopic sleeve. When the hopper of the receiving equipment at the cement silo discharge port 111 is low, the moving device 2 lowers the sleeve 12, thereby reducing the drop between the discharge point and the receiving point. This can effectively reduce the splashing of cement during unloading, thus reducing dust. It can also act as a windproof shield, reducing dust run-off caused by wind when unloading without a sleeve.

[0020] In a preferred embodiment, the moving device 2 includes an electric actuator 21 and a clamp 22 disposed at the end of the sleeve 12, with the extension rod of the electric actuator 21 connected to the clamp 22.

[0025] Setting up an enclosed room 14 provides a large space, allowing equipment that easily generates dust to work within the enclosed room 14. The dust generated is then treated by a dust collection device 3, achieving the purpose of centralized dust disposal.

[0026] In a preferred embodiment, the dust collection device 3 includes a dust collection hood 31 fixedly installed on the top of the enclosed room 14, and an axial flow exhaust fan 32 is provided inside the dust collection hood 31. The air outlet of the axial flow exhaust fan 32 is connected to the sedimentation tank 13 through a pipe.

[0027] In the preferred embodiment, the enclosed room 14 is constructed using steel pipes and covered with tarpaulins on the outside of the steel pipes; it can also be a steel plate house or the like.
