Description

Technical Field

[0001] The invention relates to the technical field of recycling waste ceramic paper, and in particular to a device for recycling waste ceramic paper in a waste honeycomb denitration catalyst. Background Art

[0002] The honeycomb denitrification catalyst module consists of several catalyst monomers and an external packaging iron frame. Aluminum silicate ceramic paper is used as a seal and buffer between the honeycomb denitrification catalyst monomers to allow the flue gas in the reactor to enter the catalyst monomer pores, ensuring that the flue gas nitrogen oxide emissions after combustion meet the standards. In the regeneration process of the waste honeycomb denitrification catalyst, in order to ensure that each monomer meets the regeneration standard, it is necessary to dismantle the entire waste denitrification honeycomb catalyst monomer and dismantle the monomer that does not meet the regeneration standard.

[0029] The working principle and beneficial effects of the above technical solution are as follows: the monomers that do not meet the regeneration standards in the honeycomb denitration catalyst module are removed, the aluminum silicate ceramic papers used as seals and buffers between the honeycomb denitration catalyst monomers are collected together, and then the ceramic papers are sent to the first cleaning chamber for preliminary cleaning. The purpose of the preliminary cleaning is to remove some particles and fly ash attached to the surface of the ceramic paper. The ceramic paper after the preliminary cleaning is sent to the second cleaning chamber through the first conveying device, and the ceramic paper is foamed in the second cleaning chamber. The foamed ceramic paper fragments are sent to the extrusion chamber through the second conveying device, and then extruded and formed by the hydraulic press according to the mold. The formed ceramic paper enters the cutting chamber through the third conveying device, and then the cutting blade cuts the ceramic paper to a certain specification. The cut ceramic paper is reused in the assembly process of the unit body prepared by the denitration honeycomb catalyst, so as to realize the recycling of waste ceramic paper and greatly reduce the operating cost of processing waste ceramic paper. By washing the waste ceramic paper twice, most of the pollutants are cleaned in the first cleaning chamber, which reduces the contaminated proportion of the equipment water, reduces the difficulty of treating the contaminated wastewater, and reduces the risk of environmental pollution.

[0030] See also Figure 2 In one embodiment of the present invention, a cleaning pool 101 is provided in the first cleaning chamber 1, and a plurality of ultrasonic transmitters 102 are provided on the inner wall of the cleaning pool 101.

A drain outlet 106 is provided near the side wall of the bottom of the cleaning pool 101.

[0031] The working principle and beneficial effects of the above technical solution are as follows: waste ceramic paper is placed in a cleaning basket manually or by automated machinery, the cleaning basket is connected to a driving trolley through a connecting rod, the driving trolley is slidably connected to the basket slide rail, the driving trolley drives the cleaning basket to move along the basket slide rail, and the waste ceramic paper is placed in a cleaning tank, and ultrasonic vibration is used to cause cavitation, acceleration and straight-forward flow of water in the cleaning tank to directly and indirectly act on the liquid and the waste ceramic paper, so that some particles and fly ash attached to the surface of the waste ceramic paper are dispersed, emulsified and peeled off to achieve the purpose of cleaning. After cleaning is completed, the cleaning basket continues to slide along the basket slide rail and leaves the cleaning tank. When the cleaning basket moves to a position above the first conveying device, the cleaning basket is flipped manually or by automated machinery, and the cleaned waste ceramic paper in the cleaning basket is poured out, and the waste ceramic paper falls onto the conveyor belt of the first conveying device. The drain outlet is used to discharge the cleaning liquid in the cleaning tank, which is convenient for replacing new cleaning liquid.

[0032] See also Figure 3 In one embodiment of the present invention, the hanging basket slide rail 104 includes a straight slide rail 104a, and the straight slide rail 104a is arranged near the feed port 103 and the end of the first conveying device 3.

[0033] The working principle and beneficial effects of the above technical solution: the hanging basket slide rail is set to a closed state, and the cleaning hanging basket can move back and forth on the hanging basket slide rail. The staff only needs to load the materials at the feed port, thereby reducing labor costs.

[0034] In one embodiment of the present invention, a sewage collecting tank 107 is provided at the bottom of the cleaning pool 101 . The sewage collecting tank 107 is configured as a conical structure. A sewage outlet 108 is provided at the bottom of the sewage collecting tank 107 .

[0035] The working principle and beneficial effects of the above technical solution: when the cleaning work is completed, the sewage is allowed to stand for a while. Most of the pollutants will gradually be collected in the sewage trough under the action of gravity. The drain outlet is opened to discharge the treated water out of the cleaning pool. This part of sewage has a low pollution degree and low treatment cost. The inner wall of the cleaning pool and the cleaning basket are then cleaned through an external water pipe to keep the cleaning pool and the cleaning basket clean, reduce the possibility of erosion by pollutants, and increase service life. Finally, the clean water is discharged together with the pollutants collected in the sewage trough through the sewage outlet. Although this part of sewage has a high pollution degree and is difficult to treat, it greatly reduces the total cubic volume of sewage treated, and overall reduces the difficulty and cost of sewage treatment.

[0036] See also Figure 4 , Figure 5 or Fig. 9 In one embodiment of the present invention, a foaming pool 201 is provided in the second cleaning chamber 2, and a scraper 8 is provided in the foaming pool 201. Both ends of the scraper 8 are connected to a scraping slide 203 through a lifting rod 202. The scraping slide 203 is slidably connected to a scraping chute 204. Both ends of the scraping chute 204 are fixedly connected to the inner wall of the second cleaning chamber 2. The scraper 8 includes a scraper rod 801, a scraper plate 802 is provided below the scraper rod 801, both ends of the scraper plate 802 are rotatably connected to the scraper rod 801, the cross section of the scraper plate 802 is set as a semicircular structure, the scraper plate 802 is provided with a movable baffle 803 near the end of the second conveying device 5, the other end of the scraper plate 802 is closed, the movable baffle 803 is adapted to the cross section of the scraper plate 802, the top end of the movable baffle 803 is rotatably connected to the bottom end of the gantry 806, the gantry 806 is fixedly connected to the edge end of the scraper plate 802, and the top end of the gantry 806 is rotatably connected to the bottom end of the gantry 806. It is movably connected to the scraper rod 801, the bottom end of the movable baffle 803 overlaps the edge end of the scraper plate 802, a floating strip 804 is provided at a quarter position of the outer wall of the scraper plate 802, and a plurality of water holes 805 are provided on the surface of the scraper plate 802. The top end of the scraper rod 801 is hinged to the bottom end of one of the lifting rods 202, and the hinge point is arranged near the end of the movable baffle 803. The scraper rod 801 is provided with a sliding groove 807 away from the top end of the movable baffle 803, and a sliding block 808 is slidably connected in the sliding groove 807, and the top end of the sliding block 808 is hinged to the bottom end of another lifting rod 202.

[0037] The working principle and beneficial effects of the above technical solution are as follows: when the waste ceramic paper is completely soaked in the soaking pool, the ceramic paper absorbs water and disperses into ceramic paper fragments, and the ceramic paper fragments float on the water surface. The two lifting rods are extended synchronously by the cylinder to send the scraper to the water surface of the soaking pool. The scraper slide is connected to a driving motor, and the output end of the driving motor is connected to a walking wheel. The walking wheel is slidably connected to the scraper slide rail. Driven by the driving motor, the scraper slides on the scraper slide rail, and the scraper slide drives the lifting rod to make horizontal movement. The lifting rod drives the scraper, and the scraper moves on the water surface to complete the collection and treatment of the ceramic paper fragments floating on the water surface. When the scraper is working, as the scraper plate gradually contacts the water surface, when the floating bar contacts the water surface, the floating bar is acted upon by buoyancy, driving the scraper plate to rotate around the scraper rod until the center of the scraper plate is in the same plane as the floating bar. At this time, the scraper plate is set at a 45° angle. As the scraper moves on the water surface, the scraper plate and the scraper stem collect and process the ceramic paper fragments floating on the water surface. When a certain amount of ceramic paper fragments are collected, the cylinder is used to synchronously adjust the retraction of the two lifting rods to drive the scraper to leave the water surface. As the scraper plate leaves the water surface, under the action of gravity, the scraper plate rotates and returns to the initial position, and the collected ceramic paper fragments are The scraper will remain on the inner wall of the scraper plate, and the water hole is used to drain excess water. The scraper slide plate adjusts its horizontal position, and the lifting rod adjusts its height position to drive the scraper to move to the second conveying device position. The movable baffle is facing the second conveying device. A lifting rod close to the second conveying device end maintains a constant height, and the other lifting rod cylinder continues to work, driving the lifting rod to continue to retract, and the scraper hinged to the lifting rod deflects. Since the distance between the two lifting rods remains unchanged, when the scraper deflects, the length between the two lifting rods and the scraper rod hinge point will become longer. As the scraper deflects, one of the hinge points remains unchanged, and the other hinge point The sliding block slides in the sliding groove to adapt to the change in length between the two lifting rods and the hinge point of the scraper rod. The ceramic paper fragments collected on the inner wall of the scraper plate will slide down along the scraper plate under the action of gravity. The ceramic paper fragments push the movable baffle open and fall onto the conveyor belt of the second conveying device. When all the ceramic paper fragments fall, the lifting rod stops retracting, the cylinder works in the reverse direction, and the lifting rod extends to the same length as the other one. The position of one of the hinge points remains unchanged, and the sliding block of the other hinge point slides in the sliding groove to adapt to the change in length between the two lifting rods and the hinge point of the scraper rod until the scraper is kept level again.

[0038] In one embodiment of the present invention, the first conveying device 3 includes a first shell 301, one end of the first shell 301 is connected to the straight slide rail 104a, the other end of the first shell 301 extends into the second cleaning chamber 2, a conveyor belt is provided in the first shell 301, and a flip rod 302 is connected to the inner wall of the first shell 301, the flip rod 302 is arranged below the parallel plane of the straight slide rail 104a, and the flip rod 302 is arranged vertically to the straight slide rail 104a, and the height position of the flip rod 302 is arranged close to the side end of the cleaning basket 105.

[0039] The working principle and beneficial effects of the above technical solution: after the cleaning basket passes through the cleaning pool, when it moves to the straight slide rail, the cleaning basket touches the flip rod, and the top of the cleaning basket is connected to the basket slide rail through a connecting rod. The flip rod prevents the cleaning basket from continuing to move forward, and the cleaning basket rotates around the hinge point with the connecting rod. As the cleaning basket flips, the waste ceramic paper in the cleaning basket slides from the cleaning basket to the starting end of the first conveying device located below the straight slide rail due to the action of gravity, and the conveyor belt delivers the waste ceramic paper to the foaming pool.

[0040] See also Figure 7 In one embodiment of the present invention, the second conveying device 5 includes a second shell 501, and a vacuum adsorption machine 502 is provided at the end of the second shell 501 close to the second cleaning chamber 2, and a glue injection tube 503 is provided at the end of the vacuum adsorption machine 502 away from the second cleaning chamber 2. One end of the glue injection tube 503 is connected to the second shell 501, and the other end of the glue injection tube 503 is connected to the inorganic glue storage box. A conveyor belt is provided in the second shell 501.

[0041] The working principle and beneficial effects of the above technical solution: Before pressing, a certain proportion of inorganic glue needs to be added to the ceramic paper for mixing. The adsorption force provided by the vacuum adsorption machine cooperates with the gravity of the ceramic paper fragments to accurately move the ceramic paper fragments collected on the scraper plate to the conveyor belt. The conveyor belt transports the ceramic paper fragments into the extrusion chamber. During the transportation process, the glue injection tube simultaneously adds inorganic glue to the ceramic paper fragments, and then the conveyor belt transports the ceramic paper fragments mixed with the inorganic glue to the extrusion chamber for extrusion molding.

[0042] See also Figure 8In one embodiment of the present invention, the third conveying device 7 includes a third shell 701, one end of the third shell 701 is connected to the extrusion chamber 4, the other end of the third shell 701 passes through the cutting chamber 6 and extends out of the cutting chamber 6, a conveying belt is arranged in the third shell 701, a drying device 702 is arranged at the bottom end of the conveying belt, the drying device 702 is arranged between the extrusion chamber 4 and the cutting chamber 6, and the drying device 702 is fixedly connected to the inner wall of the third shell 701. The drying device 702 is a Hong Kong-named GM-120 electric heating sheet.

[0043] The working principle and beneficial effects of the above technical solution are as follows: Since the ceramic paper is subjected to a foaming treatment, the ceramic paper fragments have a high water content, and inorganic glue is added before extrusion molding. After extrusion molding in the extrusion chamber, they are electrically heated by a drying device to accelerate the curing molding.
