Description

Technical Field

[0001] The invention relates to the technical field of sludge drying equipment, and in particular to sludge drying equipment with a dust removal device. Background Art

[0002] When the sludge drying equipment is working, high-temperature gas is generally introduced to heat and dry the sludge. When the high-temperature gas passes through the sludge, it will drive some of the dried dust into the airflow, so that the airflow carries dust after discharging the sludge drying device, so the discharged mixed gas needs to be dust-removed.

[0003] One of the existing ways of dust removal for sludge drying equipment is to spray atomized liquid into the mixed gas to capture and settle the dust in the gas for dust removal, and at the same time cool the high-temperature gas. It requires continuous spraying of clean water, which consumes a lot of water. Therefore, a sludge drying equipment with a dust removal device that consumes less water is needed. Summary of the invention

[0004] In order to overcome the above-mentioned technical problems, the object of the present invention is to provide a sludge drying equipment with a dust removal device. Through the arrangement of a screen plate, a partition plate and a sedimentation channel, the mixed gas is divided into fine small bubbles when passing through the screen plate during the floating process in the water tank, thereby increasing the contact area between the mixed gas and the water body. The dust in the bubbles is captured by the water body after contacting the water body, thereby achieving dust removal for the mixed gas. While preventing the mixed gas from entering the sedimentation channel through the partition plate, it facilitates the movement of dust in the water body to the sedimentation channel, thereby achieving the capture of the dust in the mixed gas and the sedimentation of the dust, thereby slowing down or avoiding the continuous increase of dust concentration in the water body, facilitating the reuse of the water body, and eliminating the need for frequent replacement of the water body, thereby reducing the consumption of water resources.

[0005] The purpose of the present invention can be achieved through the following technical solutions:

[0006] A sludge drying equipment with a dust removal device comprises a dryer body, a dust removal assembly is arranged on one side outer wall of the dryer body, the dust removal assembly comprises a water tank, the water tank comprises two panels, a partition plate is fixedly connected between both sides of the inner side walls of the two panels, a plurality of inclined sieve plates are fixedly connected from top to bottom between the inner side walls of the two panels, a guide plate is arranged above the sieve plate, a plurality of guide plates correspond to a plurality of sieve plates one by one, the panels are fixedly connected to the guide plates, an outer side wall of one of the panels is fixedly connected to an air inlet at a position below one end of a lowermost sieve plate, and an air outlet is fixedly connected to the top of the water tank A pipe is provided at the bottom end of the water tank, and a water inlet is connected to one side of the top end of the water tank for replenishing liquid in the water tank. The mixed gas enters the water tank through the air inlet. When the mixed gas passes through the mesh plate during the floating process, it is divided into fine small bubbles, thereby increasing the contact area between the mixed gas and the water body. The dust in the bubbles is captured by the water body after contacting the water body, thereby realizing dust removal for the mixed gas. Through the arrangement of multiple sieve plates and guide plates, the mixed gas moves in a zigzag shape in the water tank, thereby increasing the residence time of the gas in the water body. At the same time, the dust entering the water will continue to sink under the action of gravity, and finally gather in the sedimentation chamber.

[0007] Furthermore, the plurality of sieve plates are placed in a zigzag shape, and the two ends of two adjacent sieve plates are inverted with each other, and a V-shape is formed between two adjacent sieve plates, so that the mixed gas moves in a zigzag shape in the water tank, increasing the residence time of the gas in the water body and facilitating dust settling.

[0008] Furthermore, the screen plate includes a mesh plate, one end of which is fixedly connected to the inner wall of the adjacent partition plate, the other end of which is fixedly connected to a shielding plate, one end of which is fixedly connected to the inner wall of the adjacent partition plate, the inner wall of the panel is fixedly connected to the mesh plate and the shielding plate, and the shielding plate is used to guide dust to settle and to shield the slot one at the same time.

[0009] Furthermore, one end of the mesh plate is higher than the other end of the mesh plate, and the inclination angle of the shielding plate is greater than the inclination angle of the mesh plate, so that dust can move toward the top of the shielding plate.

[0010] Furthermore, one side wall of the partition plate is provided with a slot one at a position above the baffle plate, and one side wall of the partition plate is provided with a slot two at a position above one end of the guide plate. An inclined bottom plate is fixedly connected between the bottom ends of the two partition plates, and the height of one end of the bottom plate is higher than the height of the other end. A side wall of the bottom end of the partition plate adjacent to the other end of the bottom plate is provided with a slot three above the other end of the bottom plate. A sedimentation channel is formed between the partition plate and the inner side wall of the adjacent side of the water tank. The height of the baffle plate is greater than the height of the corresponding slot one, so that the baffle plate shields the slot one and prevents the mixed gas from directly entering the slot one.

[0011] Furthermore, the bottom end of the water tank is fixedly connected with a sewage pipe, the bottom end of the sewage pipe is installed with a sludge pump, and the output end of the sludge pump is connected with a mud pipe, so as to facilitate the cleaning of dust in the sedimentation chamber.

[0012] Furthermore, a feed port is provided at one end of the dryer body, a discharge port and an air outlet are installed at the other end of the dryer body, an air duct is connected between the air outlet and the air inlet, and one end of the mud pipe is located above the feed port, so that the dust collected in the sedimentation chamber can be directly added into the dryer body for drying.

[0013] Furthermore, the auxiliary cleaning component includes a motor, an axis rod is rotatably connected between the two ends of the inner top surface and the inner bottom surface of the water tank, the output end of the motor is fixedly connected to the top end of an adjacent axis rod, the motor is fixedly connected to the outer top surface of the water tank, slide rails are fixedly connected to both sides of the top surface of the guide plate, and a scraper is slidably connected between the two slide rails, a pull rope is fixedly connected to the middle position of the scraper, the two ends of the pull rope respectively pass through the partition plate on the adjacent side and extend to the sedimentation channel on the adjacent side, a plurality of winding wheels are fixedly sleeved on the outer side wall of the axis rod, and the plurality of winding wheels correspond to the plurality of pull ropes one by one, the two ends of the pull rope are respectively wound and fixed with the corresponding winding wheels, and the top of the two axis rods is fixedly connected to the top of the two axis rods. The motor is a servo motor that can control the number of revolutions and the direction of rotation of the output shaft. The motor output shaft drives the two shafts to rotate synchronously. When one shaft rotates, it drives the winding wheel on it to reel in one end of the pull rope. The pull rope pulls the scraper to move along the slide rail, so that the scraper scrapes the settled dust on the surface of the corresponding guide plate, pushes the dust to the slot two, and assists the dust to enter the sedimentation channel. Then the motor reverses, so that the other shaft reels in the other end of the pull rope, so that the scraper is reset and returns to the end of the guide plate away from the slot two, thereby assisting in accelerating the dust on the surface of the guide plate to enter the sedimentation channel, thereby accelerating the dust settling in the water body and reducing the rate of increase of the dust concentration in the water body.

[0014] Furthermore, a pulley is fixedly sleeved on the top end of the shaft rod, and a belt is connected between the two pulleys for transmission, so as to facilitate the synchronous rotation of the two shaft rods.

[0015] Furthermore, a dredging plate is fixedly connected to one side wall of the scraper. Through the arrangement of the dredging plate, when the scraper approaches the second slot, the dredging plate is inserted into the second slot, thereby preventing the second slot from being blocked.

[0016] Beneficial effects of the present invention:

[0017] 1. Through the arrangement of the sieve plate, the partition plate and the sedimentation channel, the mixed gas enters the water tank through the air inlet. When the mixed gas passes through the mesh plate during the floating process, it is divided into fine small bubbles, thereby increasing the contact area between the mixed gas and the water body. The dust in the bubbles is captured by the water body after contacting the water body, thereby realizing the dust removal of the mixed gas. Through the arrangement of multiple sieve plates and guide plates, the mixed gas moves in a broken line in the water tank, increasing the residence time of the gas in the water body. At the same time, the dust entering the water will continue to sink under the action of gravity, and finally enter the sedimentation channel and settle in the sedimentation chamber. While the partition plate prevents the mixed gas from entering the sedimentation channel, it facilitates the dust in the water body to move to the sedimentation channel, thereby realizing the capture of the dust in the mixed gas and the sedimentation of the dust, thereby reducing the dust concentration in the water body and realizing the reuse of the water body, thereby saving costs and water resources, and facilitating the dust removal of the mixed gas.

[0018] 2. Through the setting of the auxiliary cleaning component, the motor drives the two shafts to rotate synchronously. When one shaft rotates, it drives the winding wheel on it to reel in one end of the pull rope, and the pull rope pulls the scraper to move along the slide rail, so that the scraper scrapes the settled dust on the surface of the corresponding guide plate, and pushes the dust to the slot two, and assists the dust to enter the sedimentation channel. The dredging plate dredges the slot two, and then the motor reverses, so that the other shaft reels in the other end of the pull rope, so that the scraper is reset and returns to the end of the guide plate away from the slot two, so as to assist in accelerating the dust on the surface of the guide plate to enter the sedimentation channel, thereby accelerating the dust settling in the water body and reducing the rate of increase of the dust concentration in the water body.

[0036] Working principle: When in use, the high-temperature gas in the dryer body 100 is mixed with the powder dust dried in the sludge and discharged from the air outlet 130, and the mixed gas enters the water tank 210 through the air pipe and the air inlet 212. When the mixed gas passes through the mesh plate 241 during the floating process, it is divided into fine small bubbles, thereby increasing the contact area between the mixed gas and the water body. The dust in the bubbles is captured by the water body after contacting the water body, thereby achieving dust removal for the mixed gas. Through the arrangement of multiple sieve plates 240 and guide plates 250, the mixed gas moves in a zigzag shape in the water tank 210, increasing the residence time of the gas in the water body. At the same time, the dust entering the water will continue to sink under the action of gravity, and part of the dust falls to the guide plate 250, with the inclined setting of the guide plate 250, this part of the dust passes through the slot two 222 and enters the sedimentation channel 260, and part of the dust falls on the screen plate 240, but because the mixed gas passes through the mesh plate 241 from bottom to top, the dust is constantly lifted up and falls again. When it moves to above the shielding plate 242, the dust falls again and is guided by the shielding plate 242 to pass through the slot one 221 and enter the sedimentation channel 260. Part of the dust that falls on the bottom plate 230 is guided through the slot three 223 to enter the sedimentation channel 260. The dust in the sedimentation channel 260 enters the sedimentation chamber 270, and the sludge pump 280 is started to pump the dust in the sedimentation chamber 270 into the feed port 110 for drying to avoid silting in the sedimentation chamber 270.

[0037] Through the setting of the auxiliary cleaning component 300, the output shaft of the motor 350 rotates forward and reversely, driving one shaft rod 310 to rotate. Through the setting of the belt 340, the two shaft rods 310 rotate synchronously. When one shaft rod 310 rotates, it drives the winding wheel 320 on it to reel in one end of the pull rope 380. The pull rope 380 pulls the scraper 370 to move along the slide rail 360, so that the scraper 370 scrapes the settled dust on the surface of the corresponding guide plate 250, pushing the dust to the slot 222, and assisting the dust to enter the sedimentation channel 260. Then the motor 350 reverses, so that the other shaft rod 310 reels the other end of the pull rope 380, so that the scraper 370 is reset and returns to the end of the guide plate 250 away from the slot 222, so as to assist in accelerating the dust on the surface of the guide plate 250 to enter the sedimentation channel 260, thereby accelerating the dust sedimentation in the water body and reducing the increase rate of the dust concentration in the water body.
