Description

Technical Field

[0001] The utility model belongs to the technical field of gas dust removal, and in particular relates to an inertial collision pre-dust removal device. Background Art

[0002] A large amount of dust is generated when the factory workshop is in operation. This dust not only pollutes the environment, but also affects the health of workers when inhaled. When the dust reaches a certain concentration, it will cause a dust explosion. In actual production, it is essential to collect and treat the dust through a dust collector.

[0003] Before the dust collector performs dust removal, a device is usually used to pre-dust the gas to screen out larger dust in the gas. In this way, the dust removal effect will be better when the dust collector performs dust removal. During the pre-dust removal, dust may stick to the sieve plate, which will affect the rate of pre-dust removal. In addition, the dust generation environment is different, and different sieve plates need to be replaced to pre-dust the gas. The process of replacing the sieve plate is cumbersome and the rate is low. In view of this, the present utility model is specially proposed. Utility Model Content

[0006] In order to facilitate the dust to enter the collection box for collection better, further, the slot in the dust removal pipe is arranged at an angle.

[0007] In order to facilitate the regulation of the collection space in the collection box, further, an electric telescopic rod is fixedly connected to the lower end of the collection box, and a movable plate is fixedly connected to the telescopic end of the electric telescopic rod, and the movable plate slides against the inner wall of the collection box.

[0008] In order to provide convenience for the staff, further, the cleaning plate is hingedly connected to the collection box.

[0010] In order to prevent dust from accumulating on the upper end of the sieve plate, further, a handle is provided on the upper end of the sieve plate.

[0011] After adopting the above technical scheme, the utility model has the following beneficial effects compared with the prior art: Compared with the existing gas pre-dust removal technology, the utility model removes the dust stuck on the screen plate through the coordinated use of scrapers, latches and limit blocks, and effectively improves the efficiency of replacing the screen plate.

DETAILED DESCRIPTION

[0018] In order to make the purpose, technical solutions and advantages of the embodiments of the utility model clearer, the technical solutions in the embodiments will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. The following embodiments are used to illustrate the utility model but are not used to limit the scope of the utility model.

[0019] Embodiment 1:

[0020] Reference Figure 1-Figure 3, an inertial collision pre-dust removal device, comprising a dust removal pipe 1, a slot is opened in the dust removal pipe 1, a sieve plate 3 is slidably connected in the slot, a motor 6 is arranged in the sieve plate 3, a scraper strip 301 is fixedly connected to the output end of the motor 6, the scraper strip 301 is located on the side of the sieve plate 3 close to the dust inlet of the dust removal pipe 1, a collecting box 2 is connected to the side of the inner lower end of the dust removal pipe 1 close to the scraper strip 301, a cleaning plate 201 is rotatably connected to one side of the collecting box 2, a rotating plate 101 is rotatably connected to the opening of the slot, a support block 5 is fixedly connected to the side of the upper end of the dust removal pipe 1 close to the rotating plate 101, a latch 501 is plugged into the support block 5, a limit block 102 used in conjunction with the latch 501 is fixedly connected to the rotating plate 101, a contraction spring 502 is sleeved on the latch 501, and the two ends of the contraction spring 502 are respectively connected to the latch 501 and the support block 5.

[0021] When it is necessary to pre-dust the gas, the gas is introduced into the dust removal pipe 1, and the gas flow collides with the sieve plate 3 to screen out the larger dust particles in the gas, thereby realizing pre-dust removal of the gas. During the pre-dust removal of the gas, the dust will stick to the sieve plate 3, affecting the dust screening and making it inconvenient to collect the dust. The motor 6 works to drive the scraper bar 301 to rotate, and the dust stuck to the sieve plate 3 is scraped off. When the scraper bar 301 rotates, some dust particles can be thrown into the collection box 2 under the action of centrifugal force. Due to the different dust removal gases, the sieve plate 3 used for pre-dust removal also needs to be replaced. When replacing the sieve plate 3, pull the latch 501, and the latch 501 leaves the limit block 102 and rotates. By rotating the plate 101, the dust removal pipe 1 can be opened to take out the sieve plate 3 from the dust removal pipe 1 for replacement. After placing the replaced sieve plate 3 into the dust removal pipe 1, the rotating plate 101 is rotated to fit the dust removal pipe 1, and then the latch 501 is loosened. Under the action of the contraction spring 502, the latch 501 enters the limit block 102 for limit fixation, thereby realizing the replacement of the sieve plate 3. After the pre-dust removal of the gas is completed, the dust particles roll down with the inclined sieve plate 3 into the collection box 2 for collection. Compared with the existing gas pre-dust removal technology, the dust stuck on the sieve plate 3 is removed by the coordinated use of the scraper strip 301, the latch 501 and the limit block 102, and the efficiency of replacing the sieve plate 3 is effectively improved.

[0022] Embodiment 2:

[0023] Reference Figure 1-Figure 3 , an inertial collision pre-dust removal device, is basically the same as Example 1. Furthermore, the slot in the dust removal pipe 1 is arranged at an angle, and the fallen dust rolls with the screen plate 3, which better guides the dust into the collection box 2 for collection.

[0024] An electric telescopic rod 4 is fixedly connected to the lower end of the collecting box 2, and a movable plate 401 is fixedly connected to the telescopic end of the electric telescopic rod 4. The movable plate 401 slides against the inner wall of the collecting box 2. As the amount of collected dust changes, the electric telescopic rod 4 drives the movable plate 401 to move downward, thereby expanding the collecting space in the collecting box 2. The collecting space is regulated according to the amount of dust, thereby reducing the time that some gas flows through the collecting box 2 and improving work efficiency.

[0025] The cleaning plate 201 is hingedly connected to the collecting box 2. When the staff needs to open the cleaning plate 201 to clean the dust, through the setting of the hinge, after the cleaning plate 201 is opened, the staff no longer needs to hold the cleaning plate 201 all the time, which not only reduces the workload of the staff, but also facilitates the quick cleaning of the dust.

[0026] The upper end of the sieve plate 3 located on one side of the scraper strip 301 is connected to a baffle 302 through a torsion spring. The baffle 302 abuts against the inner wall of the slot of the dust removal pipe 1. The baffle 302 abuts against the dust removal pipe 1 to block dust and prevent dust from accumulating on the upper end of the sieve plate 3.

[0027] A handle is provided at the upper end of the sieve plate 3 to facilitate taking and placing the sieve plate 3.

[0028] The above are only preferred embodiments of the present invention, and are not intended to limit the present invention in any form. Although the present invention has been disclosed as above with preferred embodiments, they are not intended to limit the present invention.
