Description

Technical Field

[0001] The present invention relates to the technical field of sludge brick making, in particular to a full-automatic sludge brick making device. Background Art

[0002] Sludge bricks are a type of building brick produced using sludge as the main raw material. Sludge is a by-product produced by urban sewage treatment plants and usually contains a large amount of water, inorganic matter, organic matter and some harmful substances. Through certain treatments and processes, sludge can be converted into usable building materials, such as sludge bricks. In order to improve the properties of sludge and improve the quality of bricks, sludge is usually modified. Modification methods include adding minerals, clay, sand and other materials to adjust the adhesion and physical properties of the mixture. The sludge brick-making devices in the existing technology are usually unable to achieve automatic extrusion and molding of sludge, and cannot automatically process in batches. Summary of the Invention

[0005] Furthermore, a scraper frame is fixedly installed below the conveyor frame, a scraper plate is slidably installed on the scraper frame, a spring is provided between the scraper plate and the scraper frame, and the scraper plate is in close contact with the lower part of the upper conveyor belt.

[0006] The transmission gear is engaged with the transmission gear of the present invention and is engaged with the transmission gear of the present invention on the transmission gear.

[0007] Furthermore, a lower connecting plate is fixedly installed under the conveying frame, a sliding rod is fixedly installed on the lower connecting plate, a pull plate is slidably installed on the sliding rod, a steering wheel is rotatably installed on the lower connecting plate, a cutting frame is slidably installed on the conveying frame, a cutting line is fixedly installed on the cutting frame, a cutting spring is provided between the cutting frame and the conveying frame, one end of a cutting rope is fixedly installed on the cutting frame, the cutting rope passes around the steering wheel, the other end of the cutting rope is fixedly installed on the pull plate, and the cam cooperates with the pull plate.

[0008] The motor drives the conveyor wheel to rotate, thereby driving the upper conveyor belt to move, and drives the lower conveyor wheel to rotate through the conveyor belt, thereby driving the lower conveyor belt to move. The rotation of the conveyor wheel drives the intermediate wheel and the cam to rotate. The intermediate wheel drives the outer wheel and the outer rotating gear to rotate through the outer transmission belt, and drives the lower gear to rotate through the steering gear, thereby driving the push plate, guide rod and inner push plate to slide in the placement box. The push rod spring is compressed. When the cam rotates, it pushes the pull plate to slide along the slide rod, thereby pulling the cutting frame and cutting line down through the cutting rope. The cutting spring is compressed. When the cam is disengaged from the pull plate, the cutting frame and cutting line rise under the rebound of the cutting spring, thereby realizing the lifting and lowering of the cutting line. The sludge in the placement box is squeezed out through the extrusion port of the placement box through the inner push plate, and the extruded sludge is squeezed out in conjunction with the continuous lifting and lowering of the cutting line. The sludge is cut into blocks and then transported through the upper conveyor belt. The sludge blocks are preliminarily heated and formed by the primary heating plate, and then the surface of the sludge blocks is humidified by the nozzle. Then the sludge blocks reach the lower conveyor belt and are transported to the drying box through the lower conveyor belt. The sludge blocks are preliminarily heated and formed by the heating plate, and then the sludge blocks are transported to the placement box by the lower conveyor belt. When the sensing plate of the push plate enters the sensing range of the upper sensor, the lower solenoid valve is closed and the mixing motor starts to reverse. At this time, the sludge no longer enters the placement box from the mixing drum. When the push plate contacts the upper sensor, the motor stops rotating, and the motor shaft of the motor is not self-locking. The inner push plate resets under the rebound of the push rod spring.

[0010] The treated sludge and additives are placed in the mixing drum, and a certain amount of water is introduced through the upper water inlet pipe. At the same time, the water enters the nozzle through the lower water inlet pipe. The water volume is adjusted by the upper solenoid valve and the vertical solenoid valve. The mixing motor reverses to drive the spiral conveying shaft and the mixing frame to reverse. At this time, the spiral conveying shaft will not convey the sludge to the lower solenoid valve, but only stir the sludge and water through the mixing frame. When the sludge needs to be sent to the placement box, the lower solenoid valve is opened, and the mixing motor rotates forward to drive the spiral conveying shaft to rotate forward, and the sludge is conveyed to the placement box through the spiral conveying shaft.

A cam 120 is rotatably installed on the lower connecting plate 141, and an intermediate wheel 119 is fixedly installed on the cam 120. The intermediate wheel 119 and the conveying wheel 122 located on one side of the placement box 104 are wrapped with an oblique transmission belt 121, and the intermediate wheel 119 and the outer wheel 117 are wrapped with an outer transmission belt 118.

[0029] like Figure 2-Figure 4As shown, a lower connecting plate 141 is fixedly installed below the conveying frame 105, a sliding rod 124 is fixedly installed on the lower connecting plate 141, a pulling plate 123 is slidably installed on the sliding rod 124, a steering wheel 125 is rotatably installed on the lower connecting plate 141, a cutting frame 127 is slidably installed on the conveying frame 105, a cutting line 128 is fixedly installed on the cutting frame 127, a cutting spring 129 is arranged between the cutting frame 127 and the conveying frame 105, one end of a cutting rope 126 is fixedly installed on the cutting frame 127, the cutting rope 126 passes around the steering wheel 125, the other end of the cutting rope 126 is fixedly installed on the pulling plate 123, and the cam 120 cooperates with the pulling plate 123.

[0030] The motor 136 drives the conveying wheel 122 to rotate, thereby driving the upper conveying belt 135 to move, and drives the lower conveying wheel 134 to rotate through the conveying transmission belt 137, thereby driving the lower conveying belt 138 to move, and the conveying wheel 122 rotates to drive the intermediate wheel 119 and the cam 120 to rotate, and the intermediate wheel 119 drives the outer wheel 117 and the outer gear 116 to rotate through the outer transmission belt 118, and drives the lower gear 112 to rotate through the steering gear 115, thereby driving the push plate 107, the guide rod 108 and the inner push plate 114 to place the box 10 4 slides inside, the push rod spring 110 is compressed, and when the cam 120 rotates, it pushes the pull plate 123 to slide along the slide rod 124, thereby pulling the cutting frame 127 and the cutting line 128 down through the cutting rope 126, and the cutting spring 129 is compressed. When the cam 120 is separated from the pull plate 123, the cutting frame 127 and the cutting line 128 rise under the rebound of the cutting spring 129, thereby realizing the lifting and lowering of the cutting line 128, and the sludge in the placement box 104 is squeezed out through the extrusion port of the placement box 104 through the inner push plate 114. The extruded sludge is cut into blocks by the continuous lifting of the cutting line 128. The block sludge is then conveyed by the upper conveyor belt 135. The sludge blocks are preliminarily heated and formed by the primary heating plate 133. The surface of the sludge blocks is then humidified by the nozzle 208. The sludge blocks then reach the lower conveyor belt 138. The lower conveyor belt 138 conveys the sludge blocks to the drying box 102. The heating plate 139 performs secondary heating and preliminarily shapes the sludge blocks. The lower conveyor belt 138 then conveys the sludge blocks to the placement frame 312. When the induction plate of the push plate 107 enters the induction range of the upper sensor 132, the lower solenoid valve 202 is closed and the mixing motor 203 starts to reverse. At this time, the sludge no longer enters the placement box 104 from the mixing drum 201. When the push plate 107 contacts the upper sensor 132, the motor 136 stops rotating, and the motor shaft of the motor 136 is not self-locking. The inner push plate 114 is reset under the rebound of the push rod spring 110. When the upper conveyor belt 135 moves, the sludge remaining on the upper conveyor belt 135 is scraped off by the scraper plate 130.

[0031] like Figure 5 、 Figure 6As shown, the stirring mechanism includes a mixing motor 203 fixedly mounted on a mixing drum 201, a lower solenoid valve 202 fixedly mounted below the mixing drum 201, the lower solenoid valve 202 is fixedly mounted to the placement box 104, the lower solenoid valve 202 is electrically connected to the upper sensor 132, the mixing drum 201 is electrically connected to the upper sensor 132, an upper water inlet pipe 204 is fixedly mounted on the mixing drum 201, a lower water inlet pipe 206 is fixedly mounted on the upper water inlet pipe 204, a nozzle 208 is fixedly mounted below the lower water inlet pipe 206, an upper solenoid valve 205 is provided on the upper water inlet pipe 204, a vertical solenoid valve 207 is provided on the lower water inlet pipe 206, the upper water inlet pipe 204 is connected to an external water source, a screw conveying shaft 209 is rotatably mounted on the motor shaft of the mixing motor 203, and a mixing rack 210 is fixedly mounted on the screw conveying shaft 209.

[0032] The treated sludge and additives are placed in the mixing drum 201, and a certain amount of water is introduced through the upper water inlet pipe 204. At the same time, the water enters the nozzle 208 through the lower water inlet pipe 206. The water volume is adjusted by the upper solenoid valve 205 and the vertical solenoid valve 207. The mixing motor 203 reverses to drive the screw conveying shaft 209 and the mixing frame 210 to reverse. At this time, the screw conveying shaft 209 will not convey the sludge to the lower solenoid valve 202, but only stir the sludge and water through the mixing frame 210. When the sludge needs to be sent to the placement box 104, the lower solenoid valve 202 is opened, and the mixing motor 203 rotates forward to drive the screw conveying shaft 209 to rotate forward, and the sludge is conveyed to the placement box 104 through the screw conveying shaft 209.

[0033] like Figure 7 、 Figure 8 As shown, the firing mechanism includes a bottom slide rail 307 fixedly mounted on the bottom plate 101, a sliding seat 308 is slidably mounted on the bottom slide rail 307, a placement plate 310 is slidably mounted on the sliding seat 308, a downward pressure spring 311 is arranged between the placement plate 310 and the sliding seat 308, a placement frame 312 is detachably fixedly mounted on the placement plate 310, a hook plate 313 is fixedly mounted on the placement plate 310, a sliding card 314 is slidably mounted on the drying box 102, a sliding card spring 315 is arranged between the sliding card 314 and the drying box 102, a slope is arranged on the sliding card 314, a rebound spring 309 is arranged between the sliding seat 308 and the bottom slide rail 307, and a closing switch 316 is fixedly mounted on the bottom slide rail 307.

[0034] like Figure 7 、 Figure 8As shown, a burner is provided in the sintering box 301, a door opening motor 302 is fixedly installed on the top of the sintering box 301, a winding wheel 303 is fixedly installed on the motor shaft of the door opening motor 302, a switch door 306 is slidably installed on the sintering box 301, a top pulley 305 is rotatably installed on the sintering box 301, one end of a door opening rope 304 is fixedly installed on the switch door 306, the door opening rope 304 passes around the top pulley 305, and the other end of the door opening rope 304 is fixedly installed on the winding wheel 303, and the closing switch 316 is electrically connected to the door opening motor 302, the mixing motor 203, the lower solenoid valve 202 and the motor 136.

[0035] In the initial state, the rebound spring 309 is in a stretched state, and the sliding card 314 blocks the hook plate 313, so that the rebound spring 309 cannot rebound. As more and more sludge blocks enter the placement frame 312, the placement plate 310 will drop, and the downward pressure spring 311 will be compressed, thereby driving the hook plate 313 to drop. When the hook plate 313 drops below the sliding card 314, the sliding card 314 no longer blocks the hook plate 313. At this time, the rebound spring 309 rebounds, causing the sliding seat 308, the placement plate 310 and the placement frame 312 to enter the sintering box 301 with the sludge blocks. The sliding seat 308 contacts and maintains the contact state with the closing switch 316. At this time, the door opening motor 302 drives the winding. The wheel 303 rotates, thereby causing the door 306 to drop under the action of its own weight through the door opening rope 304. The sludge blocks are fired into sludge bricks in the sintering box 301. At this time, the motor 136 stops rotating, the mixing motor 203 starts to reverse, and the lower solenoid valve 202 is closed. After the firing is completed and the temperature drops, the sliding seat 308 is manually pulled out to take out the formed sludge bricks. After the placement plate 310 and the sliding seat 308 contact the sliding card 314, the sliding card 314 will be lifted up by the slope of the sliding card 314, and the sliding card spring 315 is compressed. When the hook plate 313 passes the sliding card 314, the sliding card spring 315 rebounds, causing the sliding card 314 to limit the hook plate 313 again.

[0036] The working principle of the fully automatic sludge brick-making device disclosed in the present invention is: the treated sludge and additives are placed in the mixing drum 201, and a certain amount of water is introduced through the upper water inlet pipe 204. At the same time, the water enters the nozzle 208 through the lower water inlet pipe 206, and the water volume is adjusted by the upper solenoid valve 205 and the vertical solenoid valve 207. The mixing motor 203 reverses to drive the spiral conveying shaft 209 and the mixing frame 210 to reverse. At this time, the spiral conveying shaft 209 will not convey the sludge to the lower solenoid valve 202, but only stir the sludge and water through the mixing frame 210. When the sludge needs to be sent to the placement box 104, the lower solenoid valve 202 is opened, and the mixing motor 203 rotates forward to drive the spiral conveying shaft 209 to rotate forward, and the sludge is conveyed to the placement box 104 through the spiral conveying shaft 209. The motor 136 drives the conveying wheel 122 to rotate, thereby driving the upper conveying belt 135 to move, and drives the lower conveying wheel 134 to rotate through the conveying transmission belt 137, thereby driving the lower conveying belt 138 to move, and the conveying wheel 122 rotates to drive the intermediate wheel 119 and the cam 120 to rotate, and the intermediate wheel 119 drives the outer wheel 117 and the outer gear 116 to rotate through the outer transmission belt 118, and drives the lower gear 112 to rotate through the steering gear 115, thereby driving the push plate 107, the guide rod 108 and the inner push plate 114 to place the box 10 4 slides inside, the push rod spring 110 is compressed, and when the cam 120 rotates, it pushes the pull plate 123 to slide along the slide rod 124, thereby pulling the cutting frame 127 and the cutting line 128 down through the cutting rope 126, and the cutting spring 129 is compressed. When the cam 120 is separated from the pull plate 123, the cutting frame 127 and the cutting line 128 rise under the rebound of the cutting spring 129, thereby realizing the lifting and lowering of the cutting line 128, and the sludge in the placement box 104 is squeezed out through the extrusion port of the placement box 104 through the inner push plate 114. The extruded sludge is cut into blocks by the continuous lifting of the cutting line 128. The block sludge is then conveyed by the upper conveyor belt 135. The sludge blocks are preliminarily heated and formed by the primary heating plate 133. The surface of the sludge blocks is then humidified by the nozzle 208. The sludge blocks then reach the lower conveyor belt 138. The lower conveyor belt 138 conveys the sludge blocks to the drying box 102. The heating plate 139 performs secondary heating and preliminarily shapes the sludge blocks. The lower conveyor belt 138 then conveys the sludge blocks to the placement frame 312. When the induction plate of the push plate 107 enters the induction range of the upper sensor 132, the lower solenoid valve 202 is closed and the mixing motor 203 starts to reverse. At this time, the sludge no longer enters the placement box 104 from the mixing drum 201. When the push plate 107 contacts the upper sensor 132, the motor 136 stops rotating, and the motor shaft of the motor 136 is not self-locking. The inner push plate 114 is reset under the rebound of the push rod spring 110. When the upper conveyor belt 135 moves, the sludge remaining on the upper conveyor belt 135 is scraped off by the scraper plate 130.In the initial state, the rebound spring 309 is in a stretched state, and the sliding card 314 blocks the hook plate 313, so that the rebound spring 309 cannot rebound. As more and more sludge blocks enter the placement frame 312, the placement plate 310 will drop, and the downward pressure spring 311 will be compressed, thereby driving the hook plate 313 to drop. When the hook plate 313 drops below the sliding card 314, the sliding card 314 no longer blocks the hook plate 313. At this time, the rebound spring 309 rebounds, causing the sliding seat 308, the placement plate 310 and the placement frame 312 to enter the sintering box 301 with the sludge blocks. The sliding seat 308 contacts and maintains the contact state with the closing switch 316. At this time, the door opening motor 302 drives the winding. The wheel 303 rotates, thereby causing the door 306 to drop under the action of its own weight through the door opening rope 304. The sludge blocks are fired into sludge bricks in the sintering box 301. At this time, the motor 136 stops rotating, the mixing motor 203 starts to reverse, and the lower solenoid valve 202 is closed. After the firing is completed and the temperature drops, the sliding seat 308 is manually pulled out to take out the formed sludge bricks. After the placement plate 310 and the sliding seat 308 contact the sliding card 314, the sliding card 314 will be lifted up by the slope of the sliding card 314, and the sliding card spring 315 is compressed. When the hook plate 313 passes the sliding card 314, the sliding card spring 315 rebounds, causing the sliding card 314 to limit the hook plate 313 again.
