[0002] Sludge bricks are a type of building bricks produced using sludge as the main raw material. Sludge is a by-product generated by urban sewage treatment plants and usually contains a large amount of water, inorganic substances, organic substances, and some harmful substances. Through certain treatments and processes, sludge can be transformed into usable building materials such as sludge bricks. In order to improve the properties of sludge and the quality of bricks, the sludge is usually subjected to modification treatment.

An inclined transmission belt is wound around the intermediate wheel and a conveying wheel located on one side of the placement box. An outer side transmission belt is wound around the intermediate wheel and the outer side wheel.

[0007] Further, a lower connecting plate is fixedly installed below the conveying frame. A sliding rod is fixedly installed on the lower connecting plate. A pulling 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 wire is fixedly installed on the cutting frame. A cutting spring is arranged between the cutting frame and the conveying frame. One end of a cutting pulling rope is fixedly installed on the cutting frame. The cutting pulling rope bypasses the steering wheel. The other end of the cutting pulling rope is fixedly installed with the pulling plate. The cam cooperates with the pulling plate.

[0008] The motor drives the conveyor wheel to rotate, thereby driving the upper conveyor belt to move. The conveyor belt drives the lower conveyor wheel to rotate, thereby driving the lower conveyor belt to move. The rotation of the conveyor wheel drives the middle wheel and the cam to rotate. The middle wheel drives the outer wheel and the outer rotating gear to rotate through the outer conveyor belt. The lower gear is driven to rotate through the steering gear, thereby driving the push plate, the guide rod, and the inner push plate to slide in the placement box. The push rod spring is compressed. When the cam rotates, it will push the pull plate to slide along the slide rod, thereby pulling the cutting frame and the cutting wire down by cutting the pull rope. The cutting spring is compressed. When the cam disengages from the pull plate, the cutting frame and the cutting wire rise under the resilience of the cutting spring, thereby realizing the lifting of the cutting wire. The sludge in the placement box is extruded through the extrusion port of the placement box by the inner push plate, and in cooperation with the continuous lifting of the cutting wire, the extruded sludge is cut into blocks. Subsequently, the blocky sludge is conveyed by the upper conveyor belt. The sludge block is preliminarily heated and formed by the primary heating plate. Subsequently, the sludge block is surface humidified by the nozzle. Subsequently, the sludge block reaches the lower conveyor belt, and the sludge block is conveyed to the drying box by the lower conveyor belt. The sludge block is secondarily heated and preliminarily formed by the heating sheet. Subsequently, the lower conveyor belt conveys the sludge block to the placement frame. When the induction piece of the push plate enters the induction range of the upper inductor, the lower solenoid valve closes, and the mixing motor starts to reverse. At this time, the sludge no longer enters the placement box from the mixing cylinder. When the push plate contacts the upper inductor, the motor stops rotating, and the motor shaft of the motor is not self-locking. The inner push plate resets under the resilience of the push rod spring. When the upper conveyor belt is moving, the residual sludge on the upper conveyor belt is scraped off by the sludge scraping plate.

[0009] Further, the stirring mechanism includes a mixing motor fixedly installed on the mixing cylinder. A lower solenoid valve is fixedly installed below the mixing cylinder. The lower solenoid valve is fixedly installed with the placement box. The lower solenoid valve is electrically connected to the upper inductor. The mixing cylinder is electrically connected to the upper inductor. An upper water inlet pipe is fixedly installed on the mixing cylinder. A lower water inlet pipe is fixedly installed on the upper water inlet pipe. A nozzle is fixedly installed below the lower water inlet pipe.

The upper water inlet pipe is connected to an external water source. A spiral conveyor shaft is rotatably installed on the motor shaft of the mixing motor. A mixing frame is fixedly installed on the spiral conveyor shaft.

[0010] The treated sludge and the additive are put into the mixing cylinder. At the same time, 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 rotates reversely to drive the spiral conveyor shaft and the mixing frame to rotate reversely. At this time, the spiral conveyor shaft does not convey the sludge to the lower solenoid valve, and only the mixing frame stirs the sludge and water. When it is necessary to send the sludge into the placement box, the lower solenoid valve is opened, and the mixing motor rotates forward to drive the spiral conveyor shaft to rotate forward, and the sludge is conveyed to the placement box through the spiral conveyor shaft.

[0011] Further, the firing mechanism includes a bottom slide rail fixedly installed on the bottom plate. A sliding seat is slidably installed on the bottom slide rail. A placement plate is slidably installed on the sliding seat. A pressing spring is provided between the placement plate and the sliding seat. A placement frame is detachably and fixedly installed on the placement plate. A hook plate is fixedly installed on the placement plate. A sliding card is slidably installed on the drying box. A sliding card spring is provided between the sliding card and the drying box. A slope is provided on the sliding card. A return spring is provided between the sliding seat and the bottom slide rail. A closing switch is fixedly installed on the bottom slide rail.

[0012] Further, a burner is provided inside the sintering box. An opening door motor is fixedly installed on the top of the sintering box. A winding wheel is fixedly installed on the motor shaft of the opening door motor. A switch door is slidably installed on the sintering box. A top pulley is rotatably installed on the sintering box. One end of an opening door rope is fixedly installed on the switch door. The opening door rope bypasses the top pulley. The other end of the opening door rope is fixedly installed on the winding wheel. The closing switch is electrically connected to the opening door motor, the mixing motor, the lower solenoid valve, and the motor.

[0013] In the initial state, the return spring is in a stretched state. The sliding card blocks the hook plate, preventing the return spring from rebounding. As more and more sludge blocks enter the placement frame, the placement plate will descend, compressing the pressing spring, thereby driving the hook plate to descend. When the hook plate descends below the sliding card, the sliding card no longer blocks the hook plate. At this time, the return spring rebounds, causing the sliding seat, the placement plate, and the placement frame to carry the sludge blocks into the sintering box. The sliding seat contacts and maintains contact with the closing switch. At this time, the opening door motor drives the winding wheel to rotate, so that the switch door descends under its own weight through the opening door rope. The sludge blocks are fired into sludge bricks inside the sintering box. And at this time, the motor stops rotating, the mixing motor starts to reverse, and the lower solenoid valve closes. After firing is completed and after cooling, manually pull out the sliding seat and take out the formed sludge bricks. After the placement plate and the sliding seat contact the sliding card, the sliding card will be pushed up through the slope of the sliding card, compressing the sliding card spring. When the hook plate passes through the sliding card, the sliding card spring rebounds, causing the sliding card to re-limit the hook plate.

[0014] The beneficial effects of the present invention compared with the prior art are as follows: (1) When the motor of the stirring mechanism of the present invention rotates in reverse, it can fully stir and mix raw materials such as sludge, additives, and water, and when the motor rotates forward, it will convey the sludge in the mixing cylinder to the placement box; (2) When the conveying mechanism of the present invention conveys sludge on the upper conveyor belt, it intermittently cuts the sludge and cuts the extruded sludge into equal-length blocks, with a high degree of automation; (3) The inner push plate of the present invention drives the upper conveyor belt and the lower conveyor belt to move while pushing out the placement box, so that the extrusion of sludge is synchronized with the subsequent conveyance of sludge blocks, with good continuity; (4) When the number of sludge blocks in the placement frame of the firing mechanism of the present invention reaches a certain level, it automatically enters the sintering box for firing, and at the same time stops conveying and extruding sludge, realizing automatic start and stop.

A lower gear 112, a steering gear 115 and an outer rotating gear 116 are rotatably installed on the lower frame 113. The lower gear 112 meshes with the push rod rack 109. An outer side wheel 117 is fixedly installed on the outer rotating gear 116. The lower gear 112 meshes with the steering gear 115. The steering gear 115 meshes with the outer rotating gear 116.

An outer side transmission belt 118 is wound around the intermediate wheel 119 and the outer side wheel 117.

[0029] As Figures 2-4As shown in the figure, 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 wire 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 pulling rope 126 is fixedly installed on the cutting frame 127. The cutting pulling rope 126 bypasses the steering wheel 125. The other end of the cutting pulling rope 126 is fixedly installed with the pulling plate 123. The cam 120 cooperates with the pulling plate 123.

[0030] The motor 136 drives the conveying wheel 122 to rotate, thereby driving the upper conveyor belt 135 to move. The lower conveyor wheel 134 is driven to rotate through the conveying transmission belt 137, thereby driving the lower conveyor belt 138 to move. The rotation of the conveying wheel 122 drives the intermediate wheel 119 and the cam 120 to rotate. The intermediate wheel 119 drives the outer wheel 117 and the outer rotating gear 116 to rotate through the outer transmission belt 118. The lower gear 112 is driven to rotate through the steering gear 115, thereby driving the push plate 107, the guide rod 108 and the inner push plate 114 to slide in the placement box 104. The push rod spring 110 is compressed. When the cam 120 rotates, it will push the pulling plate 123 to slide along the sliding rod 124, thereby pulling the cutting frame 127 and the cutting wire 128 to descend through the cutting pulling rope 126. The cutting spring 129 is compressed. When the cam 120 is separated from the pulling plate 123, the cutting frame 127 and the cutting wire 128 rise under the resilience of the cutting spring 129, thereby realizing the lifting of the cutting wire 128. The sludge in the placement box 104 is extruded through the extrusion port of the placement box 104 by the inner push plate 114, and in cooperation with the continuous lifting of the cutting wire 128, the extruded sludge is cut into blocks. Subsequently, the blocky sludge is conveyed by the upper conveyor belt 135. The sludge block is preliminarily heated and formed by the primary heating plate 133. Subsequently, the sludge block is surface-moistened by the nozzle 208. Subsequently, the sludge block reaches the lower conveyor belt 138. The sludge block is conveyed to the drying box 102 by the lower conveyor belt 138. The sludge block is secondarily heated and preliminarily formed by the heating sheet 139. Subsequently, the lower conveyor belt 138 conveys the sludge block to the placement frame 312. When the induction piece of the push plate 107 enters the induction range of the upper inductor 132, the lower solenoid valve 202 closes, and the mixing motor 203 starts to reverse. At this time, the sludge no longer enters the placement box 104 from the mixing cylinder 201. When the push plate 107 contacts the upper inductor 132, the motor 136 stops rotating, and the motor shaft of the motor 136 is not self-locking. The inner push plate 114 returns to its original position under the resilience of the push rod spring 110. When the upper conveyor belt 135 is moving, the residual sludge on the upper conveyor belt 135 is scraped off by the sludge scraping plate 130.

[0031] As Figure 5 、 Figure 6As shown in the figure, the stirring mechanism includes a mixing motor 203 fixedly installed on the mixing cylinder 201.

A nozzle 208 is fixedly installed below the lower water inlet pipe 206. An upper solenoid valve 205 is arranged on the upper water inlet pipe 204. A vertical solenoid valve 207 is arranged on the lower water inlet pipe 206. The upper water inlet pipe 204 is connected to an external water source. A spiral conveyor shaft 209 is rotatably installed on the motor shaft of the mixing motor 203. A mixing frame 210 is fixedly installed on the spiral conveyor shaft 209.

[0032] Put the treated sludge and additives into the mixing cylinder 201. At the same time, 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 rotates in reverse to drive the spiral conveyor shaft 209 and the mixing frame 210 to rotate in reverse. At this time, the spiral conveyor shaft 209 will not transport the sludge into the lower solenoid valve 202. Only the mixing frame 210 is used to stir the sludge and water. When it is necessary to send the sludge into the placement box 104, the lower solenoid valve 202 is opened, and the mixing motor 203 rotates forward to drive the spiral conveyor shaft 209 to rotate forward, and the sludge is transported into the placement box 104 through the spiral conveyor shaft 209.

[0033] As Figure 7 、 Figure 8 As shown in the figure, the firing mechanism includes a bottom slide rail 307 fixedly installed on the bottom plate 101. A sliding seat 308 is slidably installed on the bottom slide rail 307. A placement plate 310 is slidably installed 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 and fixedly installed on the placement plate 310. A hook plate 313 is fixedly installed on the placement plate 310. A sliding card 314 is slidably installed 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 return spring 309 is arranged between the sliding seat 308 and the bottom slide rail 307. A closing switch 316 is fixedly installed on the bottom slide rail 307.

[0034] As Figure 7 、 Figure 8As shown, a burner is provided inside the sintering box 301. An opening motor 302 is fixedly installed at the top of the sintering box 301. A winding wheel 303 is fixedly installed on the motor shaft of the 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 an opening rope 304 is fixedly installed on the switch door 306. The opening rope 304 bypasses the top pulley 305, and the other end of the opening rope 304 is fixedly installed with the winding wheel 303. The closing switch 316 is electrically connected to the opening motor 302, the mixing motor 203, the lower solenoid valve 202, and the motor 136.

[0035] In the initial state, the return spring 309 is in a stretched state. The sliding card 314 blocks the hook plate 313, preventing the return spring 309 from rebounding. As more and more sludge blocks enter the placement frame 312, the placement plate 310 will descend, compressing the compression spring 311, thereby driving the hook plate 313 to descend. When the hook plate 313 descends below the sliding card 314, the sliding card 314 no longer blocks the hook plate 313. At this time, the return 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 remains in contact with the closing switch 316. At this time, the opening motor 302 drives the winding wheel 303 to rotate, so that the switch door 306 descends under its own weight through the opening rope 304. The sludge blocks are sintered into sludge bricks inside the sintering box 301. And at this time, the motor 136 stops rotating, the mixing motor 203 starts to reverse, and the lower solenoid valve 202 closes. After the firing is completed and the temperature drops, manually pull out the sliding seat 308 to take out the formed sludge bricks. After the placement plate 310 and the sliding seat 308 contact the sliding card 314, they will push up the sliding card 314 through the slope of the sliding card 314, compressing the slide card spring 315. When the hook plate 313 passes through the sliding card 314, the slide card spring 315 rebounds, causing the sliding card 314 to re-limit the hook plate 313.

[0036] The working principle of a fully automatic sludge brick-making device disclosed by the present invention is as follows: The treated sludge and additives are put into the mixing cylinder 201. At the same time, a certain amount of water is introduced through the upper water inlet pipe 204, and 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 rotates in reverse to drive the spiral conveyor shaft 209 and the mixing frame 210 to rotate in reverse. At this time, the spiral conveyor shaft 209 does not convey the sludge to the lower solenoid valve 202, and only the mixing frame 210 stirs the sludge and water. When it is necessary to send the sludge into the placement box 104, the lower solenoid valve 202 is opened, and the mixing motor 203 rotates forward to drive the spiral conveyor shaft 209 to rotate forward, and the sludge is conveyed to the placement box 104 through the spiral conveyor shaft 209. The motor 136 drives the conveying wheel 122 to rotate, thereby driving the upper conveyor belt 135 to move. The lower conveying wheel 134 is driven to rotate through the conveying belt 137, thereby driving the lower conveyor belt 138 to move. The rotation of the conveying wheel 122 drives the intermediate wheel 119 and the cam 120 to rotate. The intermediate wheel 119 drives the outer wheel 117 and the outer rotating gear 116 to rotate through the outer belt 118. The lower gear 112 is driven to rotate through the steering gear 115, thereby driving the push plate 107, the guide rod 108 and the inner push plate 114 to slide in the placement box 104, and the push rod spring 110 is compressed. When the cam 120 rotates, it will push the pull plate 123 to slide along the slide rod 124, thereby pulling the cutting frame 127 and the cutting wire 128 to descend through the cutting pull 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 wire 128 rise under the resilience of the cutting spring 129, thereby realizing the lifting of the cutting wire 128. The sludge in the placement box 104 is extruded through the extrusion outlet of the placement box 104 by the inner push plate 114, and in cooperation with the continuous lifting of the cutting wire 128, the extruded sludge is cut into blocks. Subsequently, the block-shaped sludge is conveyed by the upper conveyor belt 135, and the sludge block is preliminarily heated and formed by the preliminary heating plate 133. Subsequently, the surface of the sludge block is humidified by the nozzle 208. Then the sludge block reaches the lower conveyor belt 138, and the sludge block is conveyed to the drying box 102 by the lower conveyor belt 138. The sludge block is secondarily heated and preliminarily formed by the heating sheet 139. Then the lower conveyor belt 138 conveys the sludge block to the placement frame 312. When the induction piece of the push plate 107 enters the induction range of the upper inductor 132, the lower solenoid valve 202 is closed, and the mixing motor 203 starts to rotate in reverse. At this time, the sludge no longer enters the placement box 104 from the mixing cylinder 201. When the push plate 107 contacts the upper inductor 132, the motor 136 stops rotating, and the motor shaft of the motor 136 is not self-locking. The inner push plate 114 returns to its original position under the resilience of the push rod spring 110. When the upper conveyor belt 135 moves, the residual sludge on the upper conveyor belt 135 is scraped off by the sludge scraping plate 130.In the initial state, the return spring 309 is in a stretched state. The sliding clamp 314 blocks the hook plate 313, preventing the return spring 309 from rebounding. As more and more sludge blocks enter the placement frame 312, the placement plate 310 will descend, compressing the downward pressure spring 311, thereby driving the hook plate 313 to descend. When the hook plate 313 descends below the sliding clamp 314, the sliding clamp 314 no longer blocks the hook plate 313. At this time, the return spring 309 rebounds, causing the sliding seat 308, the placement plate 310, and the placement frame 312 to carry the sludge blocks into the sintering box 301. The sliding seat 308 contacts and remains in contact with the closing switch 316. At this time, the door opening motor 302 drives the winding wheel 303 to rotate, and thus through the door opening rope 304, the switch door 306 descends under its own weight. The sludge blocks are sintered into sludge bricks in the sintering box 301. And at this time, the motor 136 stops rotating, and the mixing motor 203 starts to reverse, and the lower solenoid valve 202 closes. After the firing is completed and after cooling, manually pull out the sliding seat 308 and take out the formed sludge bricks. After the placement plate 310 and the sliding seat 308 contact the sliding clamp 314, they will push up the sliding clamp 314 through the slope of the sliding clamp 314, compressing the sliding clamp spring 315. When the hook plate 313 passes through the sliding clamp 314, the sliding clamp spring 315 rebounds, causing the sliding clamp 314 to re-limit the hook plate 313.
