Technical Field

[0001] The utility model belongs to the field of granulator smoke treatment, and in particular relates to a granulator dust removal device. Background Art

[0002] A granulator is a molding machine that can make materials into specific shapes. During the production process, a large amount of smoke and dust will be generated. The smoke and dust contain a large number of dust particles, which can cause harm when inhaled by the human body. Therefore, a dust removal device needs to be installed at the exhaust of the granulator to reduce dust.

[0003] In the prior art, the concentration of smoke and dust is often reduced by spraying water with a nozzle. The dust particles in the smoke and dust will fall under the action of gravity when in contact with water, thereby achieving the dust removal effect. In order to ensure that water can be recycled, a filter is usually set to filter the water mixed with dust particles, thereby intercepting the dust particles; however, long-term use will cause the filter to be blocked, thereby affecting the filtering effect.

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] like Figures 1 to 3 As shown, the granulator dust removal device includes a water tank 1, a mixing box 2 is arranged at the upper end of the water tank 1, the lower end of the mixing box 2 is connected to the water tank 1, the upper end of the mixing box 2 is open, and an upper cover assembly 3 is arranged at the upper end of the mixing box 2, the upper cover assembly 3 includes an upper cover 31 fixedly connected to the mixing box 2, and the upper cover 31 can block its upper end; a water pipe 32 is installed on the upper cover 31, and a plurality of nozzles 33 are arranged at the lower end of the water pipe 32, and the nozzles 33 spray water in atomization to mix with the smoke and dust entering the mixing box 2; the smoke and the sprayed water are mixed in the mixing box 2, so that the water falls toward the water tank 2 with the dust particles; and a filter plate 6 is arranged at the lower end of the mixing box 2 to intercept the solid particles, and the water enters the water tank 2 for convenient recycling;

[0028] In this embodiment, an air inlet pipe 21 and an air outlet pipe 22 are respectively provided on both sides of the upper end of the mixing box 2, a fixing plate 4 is provided on one side of the mixing box 2, an air suction pump 5 is provided on the fixing plate 4, and an air inlet of the air suction pump 5 is connected to the air outlet pipe 22. Under the action of the air suction pump 5, smoke enters the mixing box 2 from the air inlet pipe 21, and after mixing with water to reduce the concentration, the remaining smoke can be discharged from the air outlet pipe 22;

[0029] In this embodiment, the upper cover 31 and the mixing box 2 are fixed by bolt connection to facilitate the removal of the upper cover 31 and the maintenance and replacement of the nozzle 33; in addition, in order to improve the sealing between the upper cover 31 and the mixing box 2, a sealing gasket is provided at the lower end of the upper cover 31.

[0030] A clearance groove 23 is provided on one side of the lower end of the mixing box 2. The clearance groove 23 passes through the side wall of the mixing box 2. The filter plate 6 is installed in the clearance groove 23. Figure 4As shown, a baffle 61 is provided on one side of the filter plate 6. By applying pressure to the baffle 61 to make it close to the side wall of the mixing box 2, the filter plate 6 can be completely inserted into the mixing box 2 and the cross section of the mixing box 2 is blocked, so that the filter plate 6 plays a filtering role; and by providing a rubber pad 62 on the side of the baffle 61 facing the mixing box 2, when the filter plate 6 blocks the cross section of the mixing box 2, the rubber pad 62 can be close to the side wall of the mixing box 2 to achieve sealing and prevent water leakage and air leakage;

[0031] It is worth mentioning that, in this embodiment, the height of the clearance groove 23 in the vertical direction is greater than the thickness of the filter plate 6, so as to prevent the particles on the filter plate 6 from being scraped into the mixing box 2 when the filter plate 6 slides toward the outside of the mixing box 2;

[0032] In this embodiment, a fixing frame 7 is provided on one side of the water tank 1, and a first cylinder 8 is fixed on the fixing frame 7. The end of the driving shaft of the first cylinder 8 is fixed to the baffle 61 and can drive the filter plate 6 to slide (in and out of the mixing box 2).

[0033] A scraper assembly 9 is provided at the upper end of the water tank 1. When the filter plate 6 slides to the scraper assembly 9, the scraper assembly 9 can act on the upper end of the filter plate 6, and as the filter plate 6 continues to slide outward, the scraper assembly 9 can scrape off the particles on the filter plate 6.

[0034] like Figure 5 As shown, the scraper assembly 9 includes a support frame 91 fixed to the upper end of the water tank 1, and a second cylinder 92 is arranged on the support frame 91. A connecting plate 93 is fixed to the end of the driving shaft of the second cylinder 92 and drives it to rise and fall. A scraper 94 is arranged below the connecting plate 93; when the filter plate 6 moves to below the scraper 94, the scraper 94 is controlled to descend and contact the filter plate 6. As the filter plate 6 continues to slide outward until the filter plate 6 completely leaves the mixing box 2 and completely passes over the scraper 94, the particles on the filter plate 6 can be scraped off, so that the upper end of the filter plate 6 can be cleaned, and the filter plate 6 can be prevented from being blocked due to long-term use, which affects the filtering effect.

[0035] After the particles on the upper end of the filter plate 6 are scraped out, the second cylinder 92 is controlled to make the connecting plate 93 rise to the highest point, and then the first cylinder 8 is controlled to make the filter plate 6 pass through the make way groove and enter the mixing box 2 until the baffle 61 presses the rubber pad 62 against the side wall of the mixing box 2, thereby achieving the filtering effect and ensuring the sealing performance at the make way groove.

[0036] In this embodiment, the connection plate 93 and the scraper plate 94 are elastically connected by a spring 95, so as to realize elastic extrusion between the scraper plate 94 and the filter plate 6;

[0037] like Figure 6As shown, two guide rods 941 are provided at the upper end of the scraper 94, and the guide rods 941 penetrate the connecting plate 93 along the vertical direction and are slidably connected thereto, and the spring 95 is sleeved on the guide rods 941, and the two ends of the spring 95 are fixedly connected to the connecting plate 93 and the scraper 94 respectively;

[0038] In addition, a frustum 942 is provided at the upper end of the guide rod 941, and the diameter of the frustum 942 is larger than the diameter of the guide rod 941. Under the elastic force of the spring 95, the frustum 942 can be tightly attached to the upper end surface of the connecting plate 93 to prevent the guide rod 941 from detaching from the connecting plate 93 and losing its guiding function.

[0039] In this embodiment, a storage box 10 is provided at the upper end of the water tank 1. The storage box 10 is located below the scraper 94 and can store the scraped particles.

[0040] Working principle:

[0041] By arranging a mixing box 2 at the upper end of the water tank 1, and arranging a water pipe 32 and a nozzle 33 on the upper cover 31, the nozzle 33 sprays atomized water to mix with the flue gas and fall with the particles; and by arranging a filter plate 6 on the mixing box 2, the particles are intercepted, and the water can enter the water tank 1 for recycling; in addition, a first cylinder 8 is arranged on the fixing frame 7 to drive the filter plate 6 to enter and exit the mixing box 2, and a scraper assembly 9 is arranged on the outer side of the mixing box 2 to act on the filter plate 6, so as to scrape off the particles on the upper end of the filter plate 6, so as to avoid clogging of the filter plate 6 due to long-term use, thereby affecting the filtering effect.
