Description

Technical Field

[0001] The utility model relates to the technical field of flash distillation feeding equipment, in particular to a flash distillation feeding device which is easy to clean. Background Art

[0002] With the large-scale popularization of electric vehicles and electrochemical energy storage, the market demand for lithium iron phosphate has increased dramatically. Iron phosphate is the precursor of lithium iron phosphate, and its demand has also increased. Patent CN 217210025 U discloses a circulation device for drying iron phosphate. In this patent, the material is transported to the dryer through a feeder, and the high-temperature gas dries the material and carries the material into the separator. The separator separates the high-temperature gas and the dried material from each other; the high-temperature gas enters the filter and filters the remaining dust, then returns to the heat exchanger and enters the gas from the outside for heat exchange, and then is discharged through the exhaust pipe. In this way, the drying efficiency is high, the dissociation effect is good, the structure is simple, and the degree of automation is high.

[0003] At present, iron phosphate is generally dried by flash evaporation. However, the particle size of iron phosphate dihydrate filter cake is fine and the material is sticky. Once the feeding screw is stuck, the iron phosphate dihydrate filter cake will dry out due to the heat transfer of the flash drying host, and the feeding screw (auger) will be stuck. At this time, it is often necessary to laboriously dismantle the entire feeding screw. The whole process is time-consuming and laborious, which is not conducive to the continuous production of iron phosphate. Therefore, a flash feeding device that can be easily cleaned is urgently needed to reduce the cleaning intensity and time, thereby facilitating the continuous production of iron phosphate.

[0037] See also Figure 1 , Figure 1 The present invention is a schematic structural diagram of a flash evaporation feeding device that is easy to clean in one embodiment of the utility model. The flash evaporation feeding device that is easy to clean comprises a shell 1, a residual material cover plate 2, a water pipe 3, a feeding part 4 and a driving part 5; the shell 1 has a channel 11, one end of the channel 11 is provided with an outlet 12, and the other end is provided with an inlet 13 and a residual material port 14; the residual material cover plate 2 is movably covered on the residual material port 14 to be able to open and close the residual material port 14; the water pipe 3 is connected to the channel 11; the feeding part 4 is movably arranged on the channel 11, and has a feeding state for sending materials from the inlet 13 to the outlet 12, and has a cleaning state for sending materials from the outlet 12 to the residual material port 14; the driving part 5 is drivingly connected to the feeding part 4, and can drive the feeding part 4 to switch between the feeding state and the cleaning state.

[0038] The utility model provides a flash evaporation feeding device that is easy to clean. When feeding the flash evaporation equipment, the driving unit 5 switches the feeding unit 4 to the feeding state, so that the material sent from the inlet 13 into the channel 11 is transported to the outlet 12 through the feeding unit 4 to enter the flash evaporation equipment. When the material is dry and stuck, high-pressure pure water is first injected into the channel 11 through the water pipe 3 to soften the dry and hardened material; then, the feeding unit 4 is switched to the cleaning state through the driving unit 5 to transport the material from the outlet 12 to the direction of the residual material port 14, so that the softened material is finally discharged from the residual material port 14; when the residual material is discharged from the feeding unit 4, the inside of the channel 11 can also be cleaned by the high-pressure water transported by the water pipe 3. In this way, the cleaning intensity can be effectively reduced, and there is no need to pull out the stuck feeding screw from the housing 1 for cleaning, saving cleaning time, which is conducive to the continuous production of iron phosphate.

[0039] In one embodiment, the channel 11 is extended in the horizontal direction, the inlet 13 is located on the upper side of the shell 1 , and the residual material port 14 is located on the lower side of the shell 1 .

[0040] In this embodiment, the inlet 13 and the residual material port 14 are respectively placed on the upper and lower sides of the shell 1, so that the feeding equipment can transport materials into the channel 11 through the inlet 13. At the same time, when the feeding part 4 is switched to the cleaning state, the material transported to the residual material port 14 can be discharged from the channel 11 under the action of its own weight, thereby improving the cleaning efficiency.

[0041] In one embodiment, a communication port 16 is provided in the middle of the channel 11 , and the water pipe 3 is connected to the communication port 16 for conveying high-pressure water into the channel 11 .

[0042] In this embodiment, the connecting port 16 connecting the channel 11 with the water pipe 3 is arranged in the middle of the channel 11, so that the high-pressure water entering the channel 11 from the connecting port 16 can penetrate into both ends of the channel 11 at the same time, thereby improving the uniformity, so that the materials at both ends can be softened synchronously, and the feeding part 4 can discharge the materials.

[0043] In one embodiment, the channel 11 is further provided with a cleaning port 15, which is located between the outlet 12 and the connecting port 16; the flash evaporation feeding device for easy cleaning also includes a cleaning cover plate 6, which is movably covered on the cleaning port 15 so as to be able to open and close the cleaning port 15.

[0044] In this embodiment, a cleaning port 15 is provided at one end of the channel 11 close to the outlet 12, that is, at the end of the channel 11 connected to the flash drying device, and is matched with the cleaning cover 6. In this way, when the flash drying device transfers heat to further dry the material in the channel 11, the cleaning cover 6 can be opened while high-pressure water is injected into the channel 11 through the water pipe 3 to clean the dried material at the cleaning port 15, thereby further improving the cleaning efficiency.

[0045] In one embodiment, see Figure 2 and Figure 3 The outer wall of the housing 1 is provided with a mounting groove 17 along its circumference, and a connecting port 16 is provided at the bottom of the mounting groove 17; the flash feeding device for easy cleaning also includes an arc plate 7, which is slidably arranged in the mounting groove 17 along the circumference of the housing 1, and is provided with a liquid passing hole 7a, which can be connected and staggered with the connecting port 16 during the sliding process of the arc plate 7, and the water pipe 3 is connected with the liquid passing hole 7a. It should be noted that in this solution, the water pipe 3 is a flexible pipe.

[0046] In this embodiment, when the material in the channel 11 is dry, the arc plate 7 is slid to the position where the liquid hole 7a is connected to the communication port 16; and when it is not necessary to inject water into the channel 11, the arc plate 7 is slid to the position where the liquid hole 7a and the communication port 16 are offset, so that the water pipe 3 is disconnected from the channel 11, and the operation is simple and convenient. It should be noted that in this solution, a driving handle 9 is provided on the outside of the arc plate 7 to facilitate the operator to hold and push the arc plate 7. In addition, a sealing ring is provided at the communication port 16 to improve the sealing performance.

[0047] In one embodiment, a plurality of mounting grooves 17 are provided, and the plurality of mounting grooves 17 are spaced apart along the axial direction of the channel 11, and a connecting port 16 is provided at the bottom of each mounting groove 17; a plurality of arc-shaped plates 7 are provided corresponding to the mounting grooves 17, and the plurality of mounting grooves 17 are slidably installed in the corresponding mounting grooves 17; the water pipe 3 includes a main pipe 31 and a plurality of branch pipes 32, and one end of the plurality of branch pipes 32 is connected to the main pipe 31, and the other end is connected to the plurality of liquid holes 7a.

[0048] In this embodiment, installation grooves 17 are arranged at intervals along the axial direction of the channel 11, and a communication port 16 is correspondingly arranged in each installation groove 17, and an arc plate 7 is slidably arranged, so that the range of high-pressure water that can be directly infiltrated and cleaned is expanded, and the time for high-pressure water to soften materials is shortened. At the same time, the position and amount of water injection can be adjusted according to actual needs to improve flexibility. It should be noted that in this solution, control valves are respectively provided on the main pipe 31 and each branch pipe 32 of the water pipe 3.

[0049] In one embodiment, see Figure 2 and Figure 4 The mounting groove 17 is provided with receiving grooves 18 on both side walls in the circumferential direction of the shell 1, respectively. The receiving groove 18 extends along the circumferential direction of the shell 1, and the side wall away from the channel 11 is provided with a locking screw hole 19 connected to the outside, and the two ends of the arc plate 7 can be slidably received in the two receiving grooves 18 respectively; the flash feeding device for easy cleaning also includes a locking screw 8, and one end of the locking screw 8 screwed in the locking screw hole 19 can extend into the receiving groove 18 and press against the arc plate 7.

[0050] In this embodiment, when the arc plate 7 slides to the position where the liquid hole 7a connects to the connecting port 16 or staggers the connecting port 16, the locking screw 8 can be tightened so that the end of the locking screw 8 extending into the receiving groove 18 is pressed against the arc plate 7 to prevent the arc plate 7 from accidentally moving, improve stability, and have a simple and reliable structure. When the position of the arc plate 7 needs to be adjusted, it is only necessary to loosen the locking screw 8. It should be noted that in this solution, an anti-skid groove is provided on the outer side of the arc plate 7 to increase the friction between the locking screw 8 and the arc plate 7.

[0051] In one embodiment, the feeding part 4 is a feeding auger, which rotates forward when in a feeding state to transport materials from the inlet 13 to the outlet 12, and reverses when in a cleaning state to transport materials from the outlet 12 to the residual material outlet 14; the driving part 5 is a driving motor, which is connected to the feeding auger drive and is used to drive the feeding auger to rotate forward and reverse.

[0052] In this embodiment, the feeding part 4 is a feeding auger, and the feeding and clearing of materials are realized by the forward and reverse rotation of the feeding auger, and the structure is simple and reliable. It should be understood that the forward and reverse rotation of the feeding auger can be realized by changing the current direction of the driving motor, which is a prior art and will not be described in detail here.

[0053] In one of the embodiments, one end of the residual material cover plate 2 is hinged to the outer shell 1, and can cover and open the residual material opening 14 when rotating, and a locking ring is provided at one end of its outer wall away from the hinged end; the outer shell 1 is provided with a fixing ring corresponding to the locking ring, and the flash feeding device for easy cleaning also includes a locking pin, which can be inserted into the locking ring and the fixing ring.

[0054] In this embodiment, the residual material cover plate 2 is hingedly connected to the housing 1, and the residual material cover plate 2 is fixed to the housing 1 through the cooperation of the locking pin, the locking ring and the fixing ring, which has a simple structure and saves costs. Correspondingly, in this solution, one end of the cleaning cover plate 6 is also hingedly connected to the housing 1 to enable the cleaning cover plate 6 to open and close the cleaning port 15. In addition, the cleaning cover plate 6 is fixed to the housing 1 through a screw connection.

[0055] In order to better understand the present invention, the following Figures 1 to 4 The technical solution of the utility model is described in detail:

[0056] When the feeding auger is stuck due to dried material, the arc plate 7 is slid to the position where the connecting port 16 is connected to the liquid hole 7a, so that high-pressure pure water can be injected into the channel 11 through the water pipe 3, and at the same time, the residual material cover 2 and the cleaning cover 6 are opened; the operator can preliminarily clean the dried material from the cleaning port 15, and after the material in the channel 11 is softened by the infiltration of high-pressure pure water, the feeding auger is driven to reverse by the driving motor, so that the material in the channel 11 is discharged from the residual material port 14, thereby improving the cleaning efficiency; after the cleaning is completed, the residual material cover 2 and the cleaning cover 6 are fixed to the housing 1, so that there is no need to pull the stuck feeding screw out of the housing 1 for cleaning, which effectively reduces the cleaning intensity and saves cleaning time, so as to facilitate the continuous production of ferric phosphate.
