Description

Technical Field

[0001] The utility model belongs to the technical field of dust suppression devices, in particular to a dust suppression device for calcium oxide production. Background Art

[0002] In the production process of calcium oxide, crusher is one of the commonly used equipment to crush the raw materials into particles of the required size. However, a large amount of dust will be generated during the crushing process, which will not only pollute the environment but also pose a threat to the health of operators. Therefore, it is particularly important to effectively control and manage the dust in the production process of calcium oxide.

[0003] At present, there are some dust suppression devices on the market, but most of them have problems such as poor dust collection effect, inconvenient cleaning, and high maintenance cost. Especially for some production scenes with large amounts of dust, existing dust suppression devices often cannot meet actual needs. Therefore, the development of an efficient, convenient, and low-cost dust suppression device for calcium oxide production has important practical significance and application value. Utility Model Content

[0004] In view of the above deficiencies in the prior art, the purpose of the utility model is to provide a dust suppression device for calcium oxide production, which has a simple structure and is easy to operate. It can effectively absorb and filter the dust generated by the crusher, significantly reduce the dust concentration at the production site, and improve the working environment.

[0005] The utility model is realized by adopting the following technical solutions:

[0006] The dust suppression device for calcium oxide production comprises a dust suction pipe, one end of which is connected to a crusher, and the other end is connected to a dust collecting box, and a filter screen and a fan are arranged on the dust suction pipe; a motor, a scraper, a dust collecting box and a slide rail are arranged in sequence from top to bottom inside the dust collecting box, and both the dust collecting box and the dust collecting box are cylindrical structures, the scraper is located inside the dust collecting box, and the scraper is connected to the motor through a telescopic rod, and the motor is fixed to the inside of the dust collecting box through a support rod; a slider is fixedly connected to the bottom of the dust collecting box, and the dust collecting box is slidably connected to the slide rail through the slider; a discharge port is arranged at the bottom of the dust collecting box, and a sealing baffle is arranged at the discharge port.

[0007] The number of the sliding blocks is more than three groups, and the sliding blocks are connected to both sides of the slide rail.

[0008] The outer side of the motor is provided with a dust cover, which is fixed on the support rod.

[0009] The top of the dust cover is a cone structure, which can effectively prevent dust from entering the motor and protect the normal operation of the motor. At the same time, the cone structure can prevent dust from accumulating on the top of the dust cover.

[0010] A blocking door is provided on the side wall of the dust collecting box, and the blocking door is hingedly connected to the side wall of the dust collecting box, so that the dust collecting box can be opened conveniently for cleaning and maintenance.

[0011] A connecting rod is fixedly connected to the bottom side wall of the dust collecting box. The connecting rod is located below the blocking door, and the other end of the connecting rod is connected to a handle.

[0012] It also includes a sealing strip, which is located between the connecting rod and the slide rail. The sealing strip plays a sealing role to prevent dust from leaking from the gap between the dust collecting box and the slide rail.

[0013] The device described works as follows:

[0014] When a crusher is used for crushing in the calcium oxide production process, the fan is started to provide power for the dust collection pipe. By generating negative pressure, airflow is formed in the dust collection pipe, and the dust generated by the crusher is sucked in through the dust collection pipe and directed to the dust collection box. The sucked dust is filtered through the filter to prevent large particles of impurities from entering the dust collection box, thereby protecting subsequent equipment and fans from damage. The dust introduced from the dust collection pipe is received by the dust collection box, the height of the scraper is controlled by the telescopic rod, and the dust entering the dust collection box is collected by the dust collection box. At the same time, the motor is started, and the scraper rotates in the dust collection box under the drive of the motor to prevent dust accumulation. When the dust in the dust box accumulates to a certain height, turn off the fan and the motor, adjust the height of the scraper to the upper outside of the dust box through the telescopic rod, pull the dust box along the slide rail through the handle, and pull the dust box out of the dust box. At this time, there are at least two sets of sliders connected to the slide rail to support the dust box. Open the sealing baffle at the bottom of the dust box to unload the dust. After unloading, push the dust box back to its original position, adjust the height of the scraper again, and continue to collect dust.

[0015] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0016] (1) The dust suppression device for calcium oxide production described in the utility model effectively absorbs and filters the dust generated by the crusher through the combined use of the dust suction pipe, the filter screen and the fan, significantly reduces the dust concentration at the production site, and improves the working environment;

[0021] In order to make the purpose and technical solution of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings.

[0022] Example 1

[0023] like Figure 1 As shown, the dust suppression device for calcium oxide production comprises a dust suction pipe 1, one end of which is connected to a crusher 2, and the other end is connected to a dust collecting box 3, and a filter screen 4 and a fan 5 are arranged on the dust suction pipe 1; a motor 6, a scraper 7, a dust collecting box 8 and a slide rail 18 are arranged in sequence from top to bottom inside the dust collecting box 3, and the dust collecting box 3 and the dust collecting box 8 are both cylindrical structures, the scraper 7 is located inside the dust collecting box 8, the scraper 7 is connected to the motor 6 through a telescopic rod 9, and the motor 6 is fixed to the inside of the dust collecting box 3 through a support rod 10; a slider 11 is fixedly connected to the bottom of the dust collecting box 8, and the dust collecting box 8 is slidably connected to the slide rail through the slider 11; a discharge port is arranged at the bottom of the dust collecting box 8, and a sealing baffle 12 is arranged at the discharge port.

[0024] The number of the sliding blocks 11 is more than three groups, and the sliding blocks 11 are connected to both sides of the slide rail.

[0025] A dust cover 13 is provided on the outer side of the motor 6 , and the dust cover 13 is fixed on the support rod 10 .

[0026] The top of the dust cover 13 is a cone structure.

[0027] A blocking door 14 is provided on the side wall of the dust box 3 , and the blocking door 14 is hingedly connected to the side wall of the dust box 3 .

[0028] A connecting rod 15 is fixedly connected to the bottom side wall of the dust collecting box 8 . The connecting rod 15 is located below the blocking door 14 . A handle 16 is connected to the other end of the connecting rod 15 .

[0029] The device further comprises a sealing strip 17 , which is located between the connecting rod 15 and the slide rail 18 .

[0030] When working, the specific steps are as follows:

[0031] When the crusher 2 starts working, the fan 5 is started. After the fan 5 is running, an airflow is formed in the dust collection pipe 1, and the dust generated by the crusher 2 is sucked in through one end of the dust collection pipe 1. The sucked dust is filtered by the filter 4 on the dust collection pipe 1, and the filtered dust is guided to the dust box 3. When the dust enters the dust box 3, the height of the scraper 7 is controlled by the telescopic rod 9 so that it is located at an appropriate position inside the dust box 8. At this time, the motor 6 is started, and the scraper 7 rotates in the dust box 8 under the drive of the motor 6, so that the dust entering the dust box 8 is evenly distributed and the dust is prevented from accumulating in the dust box 8.

[0032] As the crusher 2 continues to work, the dust in the dust box 8 will gradually accumulate. When the dust accumulates to a certain height, it needs to be cleaned. At this time, turn off the fan 5 and the motor 6, and adjust the height of the scraper 7 to the upper outside of the dust box 8 through the telescopic rod 9 to avoid interference with the operation caused by the scraper 7 during the cleaning process. Next, the operator pulls the dust box 8 through the handle 16. Since the bottom of the dust box 8 is fixedly connected with a slider 11, and the slider 11 is slidably connected to the slide rail 18, the dust box 8 can slide out of the dust box 3 smoothly along the slide rail 18. During the sliding process, at least two sets of sliders 11 are connected to the slide rail 18 to support the dust box 8 and ensure the stability and safety of the dust box 8. After the dust box 8 slides out of the dust box 3, the operator can open the sealing baffle 12 at the bottom of the dust box 8 to perform the dust unloading operation. After unloading, the sealing baffle 12 is closed, and the dust box 8 is pushed back to its original position along the slide rail 18. Finally, the height of the scraper 7 is adjusted to a proper position by the telescopic rod 9 again, the fan 5 and the motor 6 are restarted, and the dust suppression device continues to collect and clean the dust.
