Description

Technical Field

[0001] The present invention relates to the technical field of wastewater treatment, and particularly to an integrated treatment device for wastewater purification and recovery in phosphate production. Background Art

[0002] Phosphate is an important raw material in industrial production and is widely used in fields such as fertilizers, food additives, and detergents. However, a large amount of high-concentration wastewater is generated during phosphate production, which contains phosphate, heavy metal ions (such as cadmium, lead, zinc), suspended solids, and acidic or alkaline components. If directly discharged, it will cause eutrophication of water bodies, soil pollution, and damage to the ecological environment, and at the same time result in serious waste of phosphorus resources. Currently, evaporation devices are mainly used to concentrate and crystallize high-salt wastewater.

[0003] For example, the invention with publication number CN115477352A discloses an evaporation and concentration tank for treating high-salt wastewater. It drives the screw rod to rotate through the second motor, so that the lifting plate drives the wastewater to move upward. When the wastewater liquid level covers the inlet of the first water inlet pipe, it is convenient to inject an appropriate amount of wastewater into the annular intercepting pipe. The evaporator conveys high-temperature steam to the intake pipe, so that the annular intercepting pipe is in a high-temperature environment, facilitating the evaporation of water in the wastewater. The first motor drives the shaft rod to rotate, so that the bracket drives the annular intercepting pipe to rotate in the annular support shell, and the wastewater flows at different positions in the annular intercepting pipe, promoting the evaporation efficiency of the wastewater. However, the evaporation products not only include concentrated solution but also solid salt crystals may precipitate. These salt crystals may remain in the annular intercepting pipe and are inconvenient to discharge. The solid salt crystals gradually accumulate in the pipeline, which may cause partial or complete blockage of the pipeline, thus affecting the evaporation and concentration effect. In view of this, the present invention proposes an integrated treatment device for wastewater purification and recovery in phosphate production to solve the above-mentioned technical problems.

A water purification tank 105 is installed on the top of the housing 101. A first circular ring frame 102 is fixedly connected inside the housing 101. An evaporation barrel 104 is rotatably connected to the first circular ring frame 102 in a sealed manner. The evaporation barrel 104 is driven by a first driving component to rotate. The first driving component is specifically a synchronous belt, two synchronous wheels and a first motor. That is, one of the synchronous wheels is installed on the outer side wall of the evaporation barrel 104, and the other synchronous wheel is installed on the side wall of the water purification tank 105. The two synchronous wheels are connected by a synchronous belt. The first motor is installed on the top of the housing 101, and the output shaft is connected to the synchronous wheel installed on the side wall of the water purification tank 105. The first motor has an encoder and a forward and reverse function, so that the rotation position of the evaporation barrel 104 can be understood and the evaporation barrel 104 can be rotated forward and backward. A first through hole 1022 is provided at the top of the first circular ring frame 102, and a second through hole 1012 is provided on the evaporation barrel 104. The first through hole 1022 and the second through hole 1012 are located in the same vertical plane. In this way, by driving the evaporation barrel 104 to rotate through the first driving component, the first through hole 1022 and the second through hole 1012 can be made to communicate or not communicate. A water inlet pipe 106 is installed in the water purification tank 105, and the water inlet pipe 106 is communicated with the first through hole 1022. A lifting plate 107 is slidably connected in the water purification tank 105. The lifting plate 107 is driven by a second driving component to move up and down. The second driving component is specifically a combination of a second motor and a lead screw, which is a prior art, so no elaboration is given. A hot air blower 108 is installed on the bottom surface of the housing 101. The hot air blower 108 is communicated with the inside of the housing 101 through a pipeline. Heat dissipation holes 1011 for heat dissipation are provided on the housing 101; A push cylinder 111 is slidably connected to the evaporation barrel 104 in a sealed manner. The push cylinder 111 is driven by a third driving component to slide.

A guide rod 113 is fixedly connected between the first circular ring frame 102 and the housing 101. A barrel cover 114 is slidably connected to the guide rod 113. The barrel cover 114 is sealedly connected to the evaporation barrel 104 through a buckle component. A push rod 116 is fixedly connected to a side surface of the push cylinder 111 close to the barrel cover 114. When the push cylinder 111 approaches the barrel cover 114, the barrel cover 114 can be pushed open by the push rod 116.

[0031] Specifically, the snap-fit ​​component includes an elastic member 115 and a magnet 117. The elastic member 115 is arranged between the barrel cover 114 and the first circular ring frame 102. The elastic member 115 is specifically a spring. The elastic member 115 is used to reset the barrel cover 114. A magnet 117 is arranged on the side of the first circular ring frame 102 close to the barrel cover 114. The barrel cover 114 is a magnetic element. When the first circular ring frame 102 is magnetically connected to the barrel cover 114, the evaporation barrel 104 is sealed. The use of the magnet 117 can prevent the elastic member 115 from causing the barrel cover 114 to shake when it is reset, thereby affecting the sealing effect.

[0032] Specifically, the third driving component includes a first air pump 112 and a second circular frame 103. The second circular frame 103 is fixedly connected in the housing 101. The second circular frame 103 is sealed and rotatably connected to the evaporation barrel 104, and the second circular frame 103 is located at the bottom of the evaporation barrel 104, that is, the right part of the evaporation barrel 104. The bottom (that is, the right part) of the evaporation barrel 104 is circumferentially provided with air holes 1041. The second circular frame 103 is provided with a second air groove 1031.

[0033] Furthermore, a circular plate 202 is fixedly connected to the second circular ring frame 103 through a bent rod 201, a first straight rod 203 is fixedly connected to the side of the push cylinder 111 away from the opening of the evaporation barrel 104, the first straight rod 203 passes through the evaporation barrel 104 and the casing 101, a first spiral groove 2031 is arranged on the first straight rod 203, a first card ball 204 matching the first spiral groove 2031 is arranged on the circular plate 202, a scraper 205 is fixedly connected to the side of the push cylinder 111 close to the opening of the evaporation barrel 104, so that the push cylinder 111 can rotate during the sliding process, and the scraper 205 is used to scrape off the salt crystals on the inner wall of the evaporation barrel 104, and a card block 206 is fixedly connected to the side of the evaporation barrel 104 close to the air hole 1041, and the card block 206 is used to prevent the gas from expanding during evaporation and then pushing the push cylinder 111.

[0034] Further, a gear 301 is rotatably connected to the outside of the casing 101. A second straight rod 302 is fixedly connected to the side of the bucket cover 114 away from the evaporation bucket 104. The second straight rod 302 penetrates through the casing 101 and the gear 301. A movable frame 303 is slidably connected to the front and back of the casing 101. A straight pipe 304 is connected to the movable frame 303. Nozzles 305 are distributed on the straight pipe 304. The nozzles 305 are supplied with air source by a second air pump 306 installed on the outside of the casing 101. A rack 307 is installed on the movable frame 303. The rack 307 meshes with the gear 301. A second thread groove 3021 is provided on the second straight rod 302. A second clamping ball 308 matched with the second thread groove 3021 is fixedly connected inside the gear 301. The straight pipe 304 is rotatably connected to the movable frame 303.

The other end of the pull rope 402 is fixedly connected inside the casing 101 through a fixing block 403. A torsion spring is provided between the rope pulley 401 and the movable frame 303. The second air pump 306 is connected to the straight pipe 304 through a hose, and the hose is sleeved inside the straight pipe 304, so that the phenomenon of hose winding does not occur when the straight pipe 304 operates.

A drying plate 502 and a draft fan 503 are installed inside the drying box 501. Thus, by rotating the evaporation bucket 104, the second through hole 1012 is communicated with the first air groove 1021, and the evaporated hot air can be collected and re-injected into the casing 101, so that energy consumption can be reduced.

[0036] Further, stirring rods 601 are symmetrically and rotatably connected to the lifting plate 107. The two stirring rods 601 are connected by a transmission component. The transmission component is specifically two synchronous wheels and a synchronous belt, that is, synchronous wheels are installed at the bottoms of the stirring rods 601, and the two synchronous wheels are connected by a synchronous belt.

[0037] Furthermore, a collection box 702 is provided at the bottom of the casing 101. The collection box 702 is located directly below the opening of the evaporation barrel 104. A second filter screen 703 is installed in the collection box 702. The second filter screen 703 is used to filter the concentrated solution and solid salt crystals after evaporation. A knocking ball 705 for knocking the collection box 702 is connected to the bottom of the barrel cover 114 through a thin string 704, so that the collection box 702 generates vibration, thereby facilitating the collection of salt crystals and preventing the accumulation of salt crystals.

[0038] The working principle of the present invention: Connect the clean water tank 105 to external wastewater. The external wastewater is injected into the clean water tank 105, and there is a gap between the liquid level and the first filter screen 701. Then, an additive (such as lime) is injected into the clean water tank 105 to remove metal impurities (such as magnesium ions) in the wastewater. Then, the driving motor 602 is started. The driving motor 602 drives one of the stirring rods 601 to rotate slowly. The stirring rod 601 drives the other stirring rod 601 to rotate through a transmission component, so that the additive and the wastewater are stirred and mixed evenly and the reaction is accelerated. After mixing, it is left stationary for a period of time to precipitate the metal impurities inside. Since there is a gap between the liquid level and the first filter screen 701, the wastewater will not flow into the inside of the water inlet pipe 106 during the stirring process; Then, the second driving component is started. The second driving component drives the lifting plate 107 to move upward, thereby raising the wastewater liquid level. Then, the wastewater can enter the inside of the evaporation barrel 104 through the water inlet pipe 106, the first through hole 1022, and the second through hole 1012. When entering, the first filter screen 701 can filter out some floating substances (such as grease) to reduce the interference of impurities on the evaporation process and improve the evaporation efficiency; Then, the hot air blower 108 is started. The hot air blower 108 passes high-temperature hot air into the casing 101, so that the evaporation barrel 104 is in a high-temperature environment, so that the wastewater evaporates water when heated in the evaporation barrel 104. At the same time, the first driving component is started to make the evaporation barrel 104 rotate, so that the first through hole 1022 is disconnected from the second through hole 1012, and the second through hole 1012 is communicated with the first air groove 1021. Then, the first driving component drives the evaporation barrel 104 to rotate in the reverse direction, so that the wastewater inside the evaporation barrel 104 shakes, so that the wastewater can be fully evaporated in the evaporation barrel 104. At the same time, the induced draft fan 503 is started. Then, the evaporated steam flows into the drying box 501 through the second through hole 1012, the first air groove 1021, and the pipeline, and then is dried by the drying plate 502 and flows into the inside of the casing 101, so that energy loss can be reduced; After evaporation is completed, the first air pump 112 is started. Then, the first air pump 112 injects gas into the evaporation barrel 104 through a pipeline, a second air tank 1031, and an air hole 1041. Then, the gas pushes the push cylinder 111 to move towards the opening of the evaporation barrel 104, and at the same time drives the first straight rod 203 to move. While the first straight rod 203 is moving, through the cooperation with the first clamping ball 204, the first straight rod 203 rotates. Then, the first straight rod 203 drives the push cylinder 111 to rotate, and then the scraper 205 rotates. Then, the scraper 205 scrapes off the salt crystals on the inner wall of the evaporation barrel 104. The evaporated concentrated solution and solid salt crystals move towards the opening direction of the evaporation barrel 104 under the action of the push cylinder 111. Then, the ejector rod 116 contacts the barrel cover 114, and then the ejector rod 116 pushes open the barrel cover 114. Then, the barrel cover 114 slides along the guide rod 113, and then the barrel cover 114 pulls the elastic member 115, so that the elastic member 115 is pulled by the rope. Then, the elastic member 115 stores elastic potential energy. Then, the evaporated concentrated solution and solid salt crystals fall into the collection box 702 and are collected; Since the thickness of the push cylinder 111 is greater than the diameter of the second through hole 1012, the push cylinder 111 can be pushed to a position flush with the opening of the evaporation barrel 104. During the movement of the barrel cover 114, the barrel cover 114 drives the second straight rod 302 to move. Then, through the cooperation of the second threaded groove 3021 and the second clamping ball 308 of the second straight rod 302, the gear 301 rotates. Then, the gear 301 drives two movable frames 303 to approach each other through the meshing transmission with the rack 307. Then, the two movable frames 303 drive the nozzle 305 to move between the barrel cover 114 and the push cylinder 111. The second air pump 306 is started, and the second air pump 306 fills the straight pipe 304 with gas through a hose. Then, the gas is ejected from the nozzle 305. Then, the ejected gas can clean the right side of the barrel cover 114 and the left side of the push cylinder 111. At the same time, during the movement of the movable frame 303, due to the action of the pull rope 402, the rope wheel 401 rotates. Then, the torsion spring stores elastic potential energy. Then, the rope wheel 401 drives the straight pipe 304 to rotate, and then the nozzle 305 rotates. Then, the cleaning area of the nozzle 305 can be expanded; When the push cylinder 111 is pushed to a position flush with the opening of the evaporation barrel 104, the knocking ball 705 knocks on the collection box 702 through the swinging of the thin rope 704. Then, the collection box 702 vibrates, and then salt crystal accumulation is prevented. After collection, the first air pump 112 inhales air, and then drives the push cylinder 111 to reset. Then, the device resets.
