[0017] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0018] Example: Figure 1-Figure 8 As shown, the present invention provides a technical solution for a fly ash water washing liquid sludge dehydration and briquetting device, comprising a water washing liquid treatment equipment body 1 and a controller 11, wherein the water washing liquid treatment equipment body 1 comprises a separation component 2, a waste liquid treatment component 3 and a briquetting component 4, wherein a liquid outlet and a solid outlet are respectively arranged at the bottom of the separation component 2, wherein the liquid outlet cooperates with the waste liquid treatment component 3, wherein the solid outlet cooperates with the briquetting component 4, wherein a metal recovery component 5 is installed between the liquid outlet and the waste liquid treatment component 3, wherein an extrusion component 6 is installed between the solid outlet and the briquetting component 4, wherein an output end of the extrusion component 6 is connected with a pusher component 7, wherein the pusher component 7 cooperates with the briquetting component 4, wherein the separation component 2 can separate solids from liquids, wherein the waste liquid treatment component 3 can purify wastewater, and wherein the briquetting component 4 can dry the separated solids and extrude them into briquettes; Therefore, when the device is in use, the fly ash water washing liquid needs to be injected into the separation component 2 first, and the liquid and solid in the fly ash water washing liquid can be separated by the separation component 2. When the separation component 2 of the device separates the fly ash water washing liquid, it can also heat the fly ash water washing liquid, thereby drying the separated solids and heating and evaporating the separated liquid. The separated solids will enter the extrusion component 6, and the entered solids can be injected into the block making component 4 through the extrusion component 6. The loose solids are squeezed into regular blocks by the block making component 4. When the block making component 4 of the device squeezes the separated solids, it will adjust the extrusion force and the extrusion temperature according to the current humidity of the solids, thereby ensuring that the extruded solids can remain tight and will not be loose. The separated liquid will first pass through the metal recovery component 5, and part of the metal carried in the liquid will be recovered by the metal recovery component 5. The liquid after passing through the metal recovery component 5 will enter the waste liquid treatment component 3 along the guide groove 121. The separated liquid can be filtered and purified by the waste liquid treatment component 3. Because the waste liquid treatment component 3 of the device includes two groups of water storage tanks 31, one group of water storage tanks 31 can perform preliminary filtration on the waste liquid, and the other group of water storage tanks 31 can filter the waste liquid again to ensure that the discharged liquid can be reused. Therefore, when the device is in use, it can fully recover the usable substances of the fly ash water washing liquid.

[0019] like Figure 4-Figure 6As shown, in this embodiment, specifically, the separation component 2 includes a driving motor 21, a housing 22, a separation cover 23 and a separation screw 24, the output end of the driving motor 21 is connected to the separation screw 24, the separation cover 23 is installed inside the housing 22, the separation screw 24 is installed inside the separation cover 23, the driving motor 21 and the bottom of the housing 22 are fixed by multiple groups of support rods, the diameter of the separation screw 24 is gradually reduced from one end to the other end, the separation cover 23 and the housing 22 are similar in shape to the separation screw 24, the separation cover 23 is installed with a matching disk 25 near one end of the driving motor 21, and the driving motor 21 is matched with the matching disk 25; When in use, the separation component 2 of the device can separate the fly ash washing liquid. During specific use, the driving motor 21 can drive the separation screw 24 to rotate, and the separation screw 24 can convey the material when rotating. At the same time, the separation screw 24 of the device is hollow. After the material enters from one end of the separation screw 24, the material will be driven by centrifugal force to discharge solids and liquids from different openings, and then discharged between the separation screw 24 and the separation cover 23. Then, the separation screw 24, in cooperation with the separation cover 23, can better pre-treat the material and heat the separated liquid and solid to different degrees.

[0020] like Figure 5 As shown, in this embodiment, specifically, both ends of the separation cover 23 are installed inside the shell 22 through bearings, and the two ends of the separation cover 23 are semicircular respectively. A conductive copper sheet 231 is installed on the outside of one end of the separation cover 23, and a conductive sheet 221 is installed on the inside of the shell 22. The conductive sheet 221 is in contact with the conductive copper sheet 231, and the conductive sheet 221 is connected to the controller 11. A plurality of groups of heating arc plates 232 are installed on the inner wall of the separation cover 23, and the heating arc plates 232 cooperate with the separation screw 24. The conductive copper sheet 231 is connected to the heating arc plates 232, and the spacing between the heating arc plates 232 from the liquid outlet end to the solid outlet end gradually decreases; The separation cover 23 of the device can pre-treat the separated solids and liquids. When the separation cover 23 is used, it can rotate under the cooperation of the driving motor 21 and the matching disk 25. When the separation cover 23 rotates, the conductive copper sheet 231 outside the separation cover 23 can contact the conductive sheet 221 on the inner wall of the shell 22. Because the controller 11 is in contact with the conductive sheet 221, the conductive sheet 221 can guide the current into the conductive copper sheet 231. Because the conductive copper sheet 231 can introduce the current into the heating arc plate 232, the heating arc plate 232 can generate heat to heat the separated liquid and solids. Because the number of the heating arc plates 232 on the separation cover 23 gradually increases from one end to the other end, and because the number of the heating arc plates 232 at the solid outlet end is larger, higher heat can be generated, so that the heating arc plates 232 can heat the solid better, preventing the separated solid from containing a large amount of water and failing to successfully make blocks; The end of the heating arc plate 232 with less arc will heat the separated liquid, because the fly ash water washing liquid can undergo a solidification reaction, and then the separated liquid will be preheated, thereby facilitating the remaining subsequent steps.

[0021] like Figure 1-Figure 2 and Figure 4 As shown, in this embodiment, specifically, a transmission rod 211 and a driving disk 212 are installed at the output end of the driving motor 21, and the driving disk 212 and multiple groups of adjusting cylinders 213 are installed on the transmission rod 211. The driving disk 212 cooperates with the matching disk 25, and the output end of the adjusting cylinder 213 is connected to the driving disk 212; The driving disk 212 is provided with multiple groups of traction magnets and multiple groups of squeeze magnets. The matching disk 25 is also provided with multiple groups of traction magnets and multiple groups of squeeze magnets. The multiple groups of traction magnets and multiple groups of squeeze magnets are respectively staggeredly installed on the driving disk 212. The N pole of the traction magnet faces the matching disk 25, and the S pole of the squeeze magnet faces the matching disk 25. The matching disk 25 is also staggered with multiple groups of traction magnets and multiple groups of squeeze magnets. The arrangement of the traction magnets and squeeze magnets on the matching disk 25 is the same as that of the driving disk 212. The N pole of the traction magnet faces the driving disk 212, and the S pole of the squeeze magnet faces the driving disk 212. When the device driving motor 21 is in use, it can drive the transmission rod 211 and the driving disk 212 to rotate, because the transmission rod 211 is connected to the separation screw 24, and because the driving disk 212 is matched with the matching disk 25, the driving disk 212 and the matching disk 25 are matched through magnetic force, so that the driving disk 212 can drive the matching disk 25 to rotate when rotating, and then drive the separation cover 23 to rotate. Because multiple groups of adjusting cylinders 213 are installed on the transmission rod 211, the distance between the driving disk 212 and the matching disk 25 can be adjusted by adjusting the cylinders 213, and then the rotation speed of the separation cover 23 is adjusted according to the speed of separating solids and liquids.

[0022] like Figure 1-Figure 3As shown, in this embodiment, specifically, a support platform 12 is installed at the bottom of the separation component 2, the metal recovery component 5 and the extrusion component 6 are installed above the support platform 12, a guide groove 121 is opened on the support platform 12, the metal recovery component 5 is installed inside the guide groove 121, the metal recovery component 5 includes a telescopic cylinder 51, an electromagnet is installed at the output end of the telescopic cylinder 51, a recovery port 1211 is opened at the bottom of the guide groove 121, and the electromagnet cooperates with the liquid outlet; The metal recovery component 5 of the device can recover part of the metal in the fly ash washing liquid, and the extrusion component 6 can supply the separated solid to the block making component 4. When the metal recovery component 5 is in use, the telescopic cylinder 51 can drive the electromagnet at the output end to contract or extend, and the liquid outlet on the separation component 2 cooperates with the electromagnet, and the electromagnet can engage with one side of the liquid outlet. After the liquid passes through the electromagnet, part of the metal that will be magnetically attracted will be adsorbed on the electromagnet. After a period of time, the telescopic cylinder 51 will contract to stop the electromagnet on the recovery port 1211. At this time, when the electromagnet is powered off, the metal adsorbed on the electromagnet will fall off and fall into the recovery port 1211, thereby recovering some metal.

[0023] like Figure 1-Figure 3 As shown, in this embodiment, specifically, the waste liquid treatment component 3 includes two groups of water tanks 31, the two groups of water tanks 31 are connected to each other, a group of water tanks 31 close to the metal recovery component 5 is internally installed with a connecting rod 32 and multiple groups of electromagnets, the two ends of the connecting rod 32 are connected to the water tank 31 through bearings, multiple groups of levers 33 are installed on the connecting rod 32, one group of the levers 33 cooperates with the guide groove 121, each group of the levers 33 is respectively provided with a groove, and two groups of water pipes are installed between the two groups of water tanks 31; When in use, the waste liquid treatment component 3 of the device can pre-treat the liquid separated by the separation component 2. During specific use, after the separated liquid passes through the metal recovery component 5, it will enter the water storage tank 31. After the liquid enters the first water storage tank 31, the impact force of the water flow will act on the lever 33, causing the entire connecting rod 32 to rotate, thereby driving all the levers 33 to rotate, thereby stirring the liquid in the first water storage tank 31, so that the metal particles in the liquid can be adsorbed on the electromagnet in the first group of water storage tanks 31. At the same time, the two groups of water storage tanks 31 of the device will also heat the liquid at the same time, thereby pre-treating the fly ash water washing liquid, which is convenient for subsequent processing of the fly ash water washing liquid.

[0024] like Figure 2 and Figure 8As shown, in this embodiment, specifically, the extrusion assembly 6 includes an extrusion motor 61 and an extrusion tube 62, an extrusion screw 63 is installed at the output end of the extrusion motor 61, and the extrusion screw 63 is installed inside the extrusion tube 62. The material of the half of the extrusion tube 62 close to the extrusion motor 61 is metal, and the other half of the extrusion tube 62 is plastic. The end of the extrusion tube 62 away from the extrusion motor 61 is connected to the block making assembly 4; When in use, the extrusion component 6 of the device can extrude and feed the separated solids. During specific use, the extrusion motor 61 can drive the extrusion screw 63 to rotate. Because the extrusion screw 63 is installed inside the extrusion tube 62, when the extrusion screw 63 rotates, the solid entering the extrusion tube 62 will move with the rotation of the extrusion screw 63, so that the metal half of the material moves to the other half of the plastic material area of ​​the extrusion tube 62. The other half of the plastic material area of ​​the extrusion tube 62 is a plastic spring hose, and when the block making component 4 moves, it can pull the plastic spring hose to move together.

[0025] like Figure 1-Figure 3 As shown, in this embodiment, specifically, the block making component 4 includes a block making table 41, the pushing component 7 includes an arc-shaped push plate 71 and two groups of pushing cylinders 72, the arc-shaped push plate 71 and the two groups of pushing cylinders 72 are respectively installed on the block making table 41, and the output ends of the two groups of pushing cylinders 72 are respectively connected to the arc-shaped push plate 71, and the block making table 41 is provided with a block making groove 411, and a lifting plate 42 is installed at the bottom of the block making groove 411, and the lifting plate 42 is driven by a cylinder, and a humidity sensor is installed above the lifting plate 42; When the block-making component 4 of the device is in use, it can make loose solids into compact blocks. When it is used specifically, because the extrusion tube 62 is connected to the arc-shaped push plate 71, when the push cylinder 72 pushes the arc-shaped push plate 71, when it is pushed to the end above the block-making groove 411, the extrusion component 6 will squeeze the loose materials into the block-making groove 411. When the loose solids are put in, the push cylinder 72 will shrink. When shrinking, because the plastic spring hose will be shortened, part of the materials will also fill the block-making groove 411. The gap allows the loose solids to be evenly distributed in the block making groove 411. At the same time, when the feeding spring hose is contracted, a small amount of solids will fall on the block making table 41. Because the arc-shaped push plate 71 is in contact with the block making table 41, the solids remaining on the block making table 41 can be pushed into the block making groove 411 during the next injection. The solids that fall into the block making groove 411 can detect the humidity of the current solid through the humidity sensor, and then the solids can be block-made to different degrees according to the humidity of the current solid.

[0026] like Figure 1As shown, in this embodiment, specifically, a support frame 8 is installed above the block making table 41, a block making cylinder 81 is installed above the support frame 8, an extrusion block 82 is installed at the output end of the block making cylinder 81, the extrusion block 82 cooperates with the block making groove 411, and a heating plate is installed on the extrusion block 82; When there is enough loose solid inside the block making groove 411, the block making cylinder 81 can push the extrusion block 82 to act on the block making groove 411. At the same time, the extrusion block 82 of the device will control the temperature emitted by the heating plate according to the value detected by the temperature sensor, thereby accelerating the efficiency of block making, and can accurately apply different pressures and temperatures according to the state of the solid after separation, so that the produced blocks can present the best shape.

[0027] In this embodiment, specifically, the controller 11 is installed on the side of the water tank 31, and a control panel is installed on the side of the controller 11; like Figure 1-Figure 3 As shown, the water washing liquid treatment equipment body 1 can be controlled by the controller 11, and the staff can operate the entire water washing liquid treatment equipment body 1 according to the control panel on the controller 11, and can also detect various data of the current water washing liquid treatment equipment body 1 according to the data on the control panel.

[0028] Working principle: When the device is in use, the fly ash water washing liquid needs to be injected into the separation component 2 first, and the liquid and solid in the fly ash water washing liquid can be separated by the separation component 2. When the separation component 2 of the device separates the fly ash water washing liquid, it can also heat the fly ash water washing liquid, thereby drying the separated solids and heating and evaporating the separated liquid. The separated solids will enter the extrusion component 6, and the entered solids can be injected into the block making component 4 through the extrusion component 6. The loose solids are squeezed into regular blocks through the block making component 4. When the block making component 4 of the device squeezes the separated solids, it will adjust the extrusion force and the extrusion temperature according to the current humidity of the solids, thereby ensuring that the extruded solids can remain tight and will not be loose. The separated liquid will first pass through the metal recovery component 5, and part of the metal carried in the liquid will be recovered by the metal recovery component 5. The liquid after passing through the metal recovery component 5 will enter the waste liquid treatment component 3 along the guide groove 121. The separated liquid can be filtered and purified by the waste liquid treatment component 3. Because the waste liquid treatment component 3 of the device includes two groups of water storage tanks 31, one group of water storage tanks 31 can perform preliminary filtration on the waste liquid, and the other group of water storage tanks 31 can filter the waste liquid again to ensure that the discharged liquid can be reused. Therefore, when the device is in use, it can fully recover the usable substances of the fly ash water washing liquid.
