Description

Technical Field

[0001] The invention relates to the field of drying equipment, in particular to an intermittent drum drying machine for preparing butyl ammonium black medicine. Background Art

[0002] Ammonium butyl black powder is a mineral processing agent that can be used to separate polymetallic ores. Under normal circumstances, ammonium butyl black powder is a white solid powder or granules, soluble in water, and easily deliquescent in the air. In the traditional process of preparing ammonium butyl black powder, it is necessary to dry the ammonium butyl black powder to obtain solid ammonium butyl black powder from the solvent.

[0003] Related technology can refer to the Chinese patent with announcement number CN114963719B, which discloses a drying device for preparing butyl ammonium black medicine, including a heating cylinder and an inner cylinder. An evaporation groove is provided inside the heating cylinder, and the inner cylinder is arranged inside the heating cylinder. The inner cylinder is fan-shaped, and two rotating rings are symmetrically arranged on the outer wall of the heating cylinder. A bottom plate is provided under the heating cylinder, and two rotating sleeves are symmetrically arranged on the bottom plate. A rotating groove is provided in the rotating sleeve, and the rotating ring is rotatably arranged in the rotating groove. One end of the heating cylinder is connected to a first drive assembly, and the other end of the inner cylinder is connected to a second drive assembly. The sieve plate in the device can deliver all solid particles into the inner cylinder in a timely and continuous manner, thereby preventing the contact between the raw material liquid and the solid particles, so that the drying work of the precipitated moist solid particles and the evaporation work of the water in the raw material liquid can be carried out simultaneously, thereby improving the drying efficiency of the solid particles of butyl ammonium black medicine.

[0004] Regarding the above-mentioned related technologies, although the solid particles can be dried while processing the liquid raw materials, when the sieve plate moves the solid particles of butyl ammonium black medicine into the inner cylinder, as the liquid raw materials continue to evaporate, the evaporated water vapor will be dispersed in the heating cylinder, and before the liquid raw materials are completely consumed, it is difficult to completely remove the water vapor in the heating cylinder, and the water vapor will directly contact the solid particles of butyl ammonium black medicine after passing through the inlet and the filter port at the upper end of the inner cylinder. The butyl ammonium black medicine is hygroscopic, and it will become moist again after absorbing water vapor, making it difficult for the dryness of the butyl ammonium black medicine particles in the inner cylinder to meet the standard requirements before the liquid raw materials are consumed, and further drying processing is required. The secondary drying process will prolong the preparation time. Therefore, there is an urgent need for a drying device that can directly prepare dry butyl ammonium black medicine solid particles while evaporating the raw material liquid. Summary of the invention

[0005] In order to directly prepare dry butyl ammonium black medicine while evaporating the raw material liquid, the present application provides an intermittent drum dryer for preparing butyl ammonium black medicine.

[0006] The present application provides an intermittent drum drying machine for preparing butyl ammonium black medicine, which adopts the following technical solution:

[0007] An intermittent drum dryer for preparing butyl ammonium black medicine comprises a support seat and a heating cylinder, a vertical plate is fixedly arranged on the upper end of the support seat, a support ring is fixedly arranged on the vertical plate in the transverse direction, the heating cylinder is sleeved on the outer side of the support ring and is rotatably connected with the support ring, heating plates are evenly arranged in the heating cylinder, the heating cylinder is hollow in the transverse direction, the support seat is used for a feed pipe for conveying liquid raw materials into the heating cylinder, the heating cylinder is also provided with a discharge port for discharging solid particles, a drying cylinder is arranged in the heating cylinder, one end of the drying cylinder is located on the inner side of the support ring and is fixedly connected to the vertical plate, the feed pipe connects the drying cylinder with the outside, a rotating rod is coaxially fixed in the heating cylinder, the rotating rod passes through the drying cylinder and The drying cylinder rotates coaxially, and the part of the rotating rod located in the drying cylinder is provided with several support rods along the circumferential direction. A scraper parallel to the rotating rod is provided at the end of the support rod away from the rotating rod. The scraper is slidably connected to the support rod along the axial direction of the support rod. When the scraper is in the position closest to the rotating rod, the side away from the support rod contacts the inner wall of the drying cylinder, and a push plate is vertically provided on the side of the scraper close to the rotating rod. A discharge port adapted to the scraper is opened on one horizontal side of the drying cylinder, and a sealing member for sealing the discharge port is provided in the drying cylinder. A placement box corresponding to the discharge port is provided on the outer side of the drying cylinder, and the drying cylinder is provided with a pushing member, which is used to drive the scraper to move axially along the support rod.

[0008] By adopting the above technical solution, the liquid raw material is added into the drying drum through the feed pipe, so that the liquid level of the liquid raw material is lower than the discharge port, and the support seat provides support through the vertical plate and the support ring heating drum. When the heating drum rotates, the liquid raw material in the drying drum is baked through the heating plate. The water vapor generated in the drying drum during the baking process is discharged along the feed pipe. When the heating drum rotates, the support rod is driven to move by the rotating rod, and when the support rod rotates, the scraper and the push plate are driven to move. When the solid particles of butyl ammonium black medicine in the liquid raw material are precipitated and attached to the bottom of the drying drum, when the scraper moves, the solid particles of butyl ammonium black medicine are pushed along the bottom of the drying drum toward the discharge port. When the scraper is facing the discharge plate, the contact sealing member closes the discharge port, and at this time, the heating drum drives the rotating rod to stop rotating. The push plate and the scraper are driven by the push member to move away from the rotating rod along the support rod. When the scraper and the push plate move, the solid particles of ammonium butyl black medicine are discharged from the discharge port and enter the placement box. When the push member drives the scraper to reset, the blocking member is operated to close the discharge port, and the heating cylinder rotates again. While continuing to bake the liquid raw material in the drying cylinder, the solid particles in the placement box are dried. During the drying process, the placement box and the drying cylinder are not connected to each other, thereby reducing the influence of water vapor generated during the drying process of the liquid raw material on the solid particles of ammonium butyl black medicine. After the solid particles of ammonium butyl black medicine in the placement box are dried, they are discharged through the discharge port, and then while evaporating the raw material liquid, dry ammonium butyl black medicine is directly prepared.

[0009] Optionally, an exhaust pipe is arranged above the feed pipe, the exhaust pipe passes through the vertical plate and is inserted into the drying cylinder, an exhaust passage connected to the exhaust pipe is opened at one end of the drying cylinder close to the vertical plate, the end of the exhaust passage away from the exhaust pipe is located at the upper end of the drying cylinder, and the end of the exhaust pipe away from the exhaust passage is connected to an exhaust assembly.

[0010] By adopting the above technical solution, when the liquid raw material evaporates, the steam in the drying drum floats up. At this time, the vacuum assembly works to discharge the steam in the drying drum through the exhaust pipe and the exhaust channel, thereby reducing the probability of the steam condensing again and remaining in the drying drum, which is beneficial to improving the drying efficiency of the liquid raw material.

[0011] Optionally, the pushing member includes a moving plate, a pushing cylinder and a connecting rod. The vertical plate and the drying cylinder are provided with the same transverse groove, the transverse groove is arranged in the direction of the rotating rod pointing to the feeding port, the connecting rod passes through the transverse groove and is slidably connected to the moving plate along the length direction of the transverse groove, both ends of the connecting rod are fixed with baffles for blocking the transverse groove, the moving plate is located in the drying cylinder and is fixedly connected to the connecting rod, the pushing cylinder is fixedly arranged on the side of the vertical plate away from the drying cylinder, and is used to drive the connecting rod to move along the transverse groove, a sleeve is fixedly arranged on the side of the scraper close to the support rod, the sleeve is arranged on the outside of the support rod and is slidably connected to the support rod along the axial direction, an arc plate is provided on the sleeve close to the moving plate, the moving plate is provided with an arc groove adapted to the arc plate, and when the rotating rod rotates, all the arc plates are driven to pass through the moving plate along the arc groove in sequence.

[0012] By adopting the above technical solution, when any scraper is facing the discharge port, the support rod on which it is located is parallel to the transverse groove, and the arc plate is in the arc groove. At this time, the push cylinder is operated to drive the connecting rod vertically away from the rotating rod. When the connecting rod moves, the arc plate is driven to move through the moving plate, so that the arc plate drives the scraper and the push plate to move through the sleeve, thereby facilitating the discharge of the solid particles of ammonium butyl black medicine from the discharge port. The baffle is used to seal the transverse groove, thereby reducing the probability of steam in the drying cylinder leaking from the transverse groove.

[0013] Optionally, the sealing member includes a sealing plate, a moving rod and a moving block, the sealing plate is located outside the drying cylinder, and the upper end of the sealing plate is hinged to the drying cylinder, an elastic member is provided between the sealing plate and the drying cylinder, the elastic member is used to push the sealing plate to fit the drying cylinder, the moving block is located inside the drying cylinder and is slidingly connected to the drying cylinder along the length direction of the transverse groove, one end of the connecting rod is hinged to the sealing plate, and the other end is hinged to the moving block, when the elastic member is in a natural state, the moving block is between the push plate and the inner wall of the drying cylinder, and the scraper is provided with an avoidance groove adapted to the moving block.

[0014] By adopting the above technical solution, initially, the sealing plate fits with the drying cylinder under the action of the elastic member 1, thereby blocking the discharge port. At this time, the moving block is close to the rotating rod. When the scraper moves along the inner wall of the drying cylinder, the moving block passes through the avoidance port, thereby avoiding the scraper. When the scraper is facing the discharge port and moves toward the discharge port under the action of the pusher, the scraper drives the push plate to gradually approach the moving block during the movement of the scraper. After the push plate contacts the moving block, it drives the moving block away from the rotating rod. When the moving block moves, it drives the sealing plate away from the drying cylinder through the connecting rod, thereby making the sealing plate avoid the scraper, which is convenient for the scraper to discharge the solid particles of butyl ammonium black medicine from the discharge port.

[0015] Optionally, the arc plate is slidably connected to the sleeve along the length direction of the support rod, a top plate is provided on the side of the push plate away from the support plate, a straight rod parallel to the support rod is fixed to the end of the arc plate away from the rotating rod, the straight rod passes through the push plate and is fixedly connected to the top plate, and the sleeve is provided with a limiting member for limiting the relative displacement of the arc plate and the sleeve.

[0016] By adopting the above technical solution, initially, the limiting member limits the arc plate and the straight rod. When the moving block moves, the sleeve is driven to move through the arc plate. When the scraper moves to the farthest end from the rotating rod, the limiting member releases the limit on the arc plate. At this time, the moving block continues to drive the arc plate to move, so that the arc plate drives the top plate and the push plate to separate through the straight rod, so that the top plate pushes the solid particles of ammonium butyl black medicine remaining above the scraper into the placement box, thereby reducing the probability of the solid particles of ammonium butyl black medicine staying on the scraper.

[0017] Optionally, the limiting member includes a baffle ring, an elastic member 2 and an abutment block. The sleeve is provided with an annular groove along the circumferential direction. The baffle ring is located in the annular groove and is slidably connected to the sleeve along the annular groove. The elastic member 2 is located between the sleeve and the baffle ring and is used to position the baffle ring. A baffle block is fixedly provided on the side of the baffle ring away from the sleeve. When the elastic member 2 is in a natural state, the side of the baffle block close to the rotating rod contacts the arc plate, the contact block is arranged along the length direction of the transverse groove and is fixedly connected to the drying cylinder, and a guide surface is provided on the side of the baffle block away from the arc plate. When the abutment block moves along the guide surface, the baffle block is pushed to separate from the arc plate.

[0018] By adopting the above technical solution, initially, the stopper contacts with the arc plate under the action of the elastic member 2. Under the limiting action of the annular groove, when the arc plate moves, the sleeve is driven to move through the cooperation of the stop ring and the annular groove. When the scraper moves to the maximum displacement, the guide surface of the stopper contacts with the contact block, and the contact block pushes the stopper to separate from the arc plate. At this time, the moving block continues to move. When the sleeve moves to the maximum displacement, the arc plate and the sleeve undergo relative displacement, and then the top plate is driven to move through the straight rod.

[0019] Optionally, the support seat is provided with a limit block, which is slidably connected to the support seat in a direction approaching or moving away from the heating cylinder. The support seat is fixed with a positioning cylinder for driving the limit block to move. A plurality of fixed grooves adapted to the limit block are opened along the circumferential direction on the outer side of the heating cylinder. The fixed grooves correspond one-to-one to the support rods. When the limit block is inserted in any fixed groove, there is any support rod parallel to the transverse groove.

[0020] By adopting the above technical solution, initially, the limit block is at a position far away from the heating cylinder. When solid particles need to be discharged from the discharge port, the limit block is pushed close to the heating cylinder by the positioning cylinder so that the limit block is inserted in any fixed groove. At this time, the heating cylinder stops rotating, and ensures that any support rod is parallel to the transverse groove, and the corresponding arc plate stays in the arc groove, so that the scraper is opposite to the discharge port, which is beneficial to improve the positioning accuracy of the scraper.

[0021] Optionally, a sealing door, a guide rod and an arc block are provided at the discharge port. When the sealing plate is located in the discharge port, it fits with the inner wall of the discharge port. A guide groove is provided at the end of the heating cylinder. The guide groove is arranged in an arc shape. The arc block is located in the guide groove and is slidably connected to the heating cylinder along the length direction of the guide groove. The guide rod is fixed to the end of the arc block away from the axis of the heating cylinder and is arranged along the diameter direction of the heating cylinder. A connecting block is fixed at the end of the sealing door. The guide rod passes through the connecting block and is slidably connected to the connecting block, and the guide rod is provided with a positioning ring for positioning the connecting block.

[0022] By adopting the above technical scheme, the heating cylinder limits the arc block through the guide groove, and when the arc groove moves along the guide groove, it drives the guide rod to move. The guide rod limits the sealing door through the connecting block, so that the sealing door is close to or away from the heating cylinder along the guide rod, which is convenient for placing the sealing door into the discharge port or discharging from the discharge port. When the sealing door is placed into the discharge port, the connecting block is positioned by the positioning ring, so that the sealing door stays in the discharge port and blocks the discharge port, thereby reducing the diffusion of heat in the heating cylinder. When the solid particles in the placement box need to be taken out, the restriction on the connecting block is released, and the sealing door is moved along the guide rod in the direction away from the heating cylinder, and the guide rod is moved along the guide groove, so that the sealing door and the discharge port are staggered, thereby facilitating the collection of the solid particles of ammonium butyl black medicine in the placement box by the discharge port.

[0023] In summary, the present application includes at least one of the following beneficial technical effects:

[0024] 1. Add the liquid raw material into the drying drum through the feed pipe so that the liquid level of the liquid raw material is lower than the discharge port. The support seat provides support through the vertical plate and the support ring heating cylinder. When the heating cylinder rotates, the liquid raw material in the drying drum is baked through the heating plate. The water vapor generated in the drying drum during the baking process is discharged along the feed pipe. When the heating drum rotates, the support rod is driven to move by the rotating rod. When the support rod rotates, it drives the scraper and the push plate to move. When the solid particles of butyl ammonium black medicine in the liquid raw material precipitate and adhere to the bottom of the drying drum, the scraper moves and pushes the solid particles of butyl ammonium black medicine along the bottom of the drying drum toward the discharge port. When the scraper is facing the discharge plate, the contact sealing piece closes the discharge port. At this time, the heating drum drives the rotating rod to stop rotating. The push plate and the scraper are driven by the push member to move away from the rotating rod along the support rod. When the scraper and the push plate move, they drive the solid particles of ammonium butyl black medicine to be discharged from the discharge port and enter the placement box. When the push member drives the scraper to reset, the sealing member is operated to close the discharge port, and the heating cylinder rotates again. While continuing to bake the liquid raw material in the drying cylinder, the solid particles in the placement box are dried. During the drying process, the placement box and the drying cylinder are not connected to each other, thereby reducing the influence of the water vapor generated during the drying process of the liquid raw material on the solid particles of ammonium butyl black medicine. After the solid particles of ammonium butyl black medicine in the placement box are dried, they are discharged through the discharge port, thereby directly preparing dry ammonium butyl black medicine while evaporating the raw material liquid;

[0025] 2. When any scraper is facing the discharge port, the support rod on which it is located is parallel to the transverse groove, and the arc plate is in the arc groove. At this time, the push cylinder is operated to drive the connecting rod vertically away from the rotating rod. When the connecting rod moves, the arc plate is driven to move through the moving plate, so that the arc plate drives the scraper and the push plate to move through the sleeve, thereby facilitating the discharge of the solid particles of ammonium butyl black medicine from the discharge port. The baffle is used to block the transverse groove, thereby reducing the probability of steam in the drying cylinder leaking from the transverse groove. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0034] The present application is further described in detail below in conjunction with all the accompanying drawings.

[0035] The embodiment of the present application discloses an intermittent drum drying machine for preparing butyl ammonium black medicine.

[0036] Example:

[0037] Reference Figure 1 and Figure 2 An intermittent drum drying machine for preparing butyl ammonium black medicine comprises a support base 1 and a heating cylinder 2. The heating cylinder 2 is arranged horizontally. The support base 1 is vertically fixedly connected with a vertical plate 11. The vertical plate 11 is located at one end of the heating cylinder 2. A support ring 12 is fixedly provided on the end surface of the vertical plate 11 close to the heating cylinder 2. The heating cylinder 2 is sleeved on the outside of the support ring 12 and is rotatably connected to the support ring 12. A column 13 is fixedly provided at one end of the support base 1 away from the vertical plate 11. A rotating shaft is fixedly provided at one end of the heating cylinder 2 away from the vertical plate 11. The rotating shaft passes through the column 13 and is rotatably connected to the column 13. The support base 1 is provided with a rotating motor 14 for driving the heating cylinder 2 to rotate.

[0038] Reference Figure 2 and Figure 3The heating cylinder 2 is coaxially provided with a drying cylinder 3, which is located inside the support ring 12 and fixedly connected to the vertical plate 11. The heating cylinder 2 is provided with a feed pipe 151, which passes through the vertical plate 11 and the drying cylinder 3 in sequence and is connected to the drying cylinder 3. The operator transports the liquid raw material of butyl ammonium black medicine into the drying cylinder 3 along the feed pipe 151. A plurality of heating plates 21 are installed inside the heating cylinder 2, which generate heat when working. When the heating cylinder 2 rotates, the drying cylinder 3 is baked by the heating plates 21, so that the water in the liquid raw material evaporates and the solid particles of butyl ammonium black medicine are prepared.

[0039] Reference Figure 2 and Figure 4 The heating cylinder 2 is also provided with an exhaust pipe 152, which is located above the feed pipe 151 and extends through the vertical plate 11 to the drying cylinder 3. The drying cylinder 3 is provided with an exhaust passage connected to the exhaust pipe 152. The end of the exhaust passage 31 away from the exhaust pipe 152 extends to the upper end of the drying cylinder 3 and is connected to the interior of the drying cylinder 3. An exhaust assembly 153 is installed at the end of the exhaust pipe 152 away from the exhaust passage 31. When the exhaust assembly 153 is working, the gas in the exhaust pipe 152 is exhausted, and then the steam generated in the drying cylinder 3 is exhausted through the exhaust pipe 152 and the exhaust passage 31, thereby reducing the probability of the steam re-entering the liquid raw material after condensing in the drying cylinder 3, which is conducive to improving the drying efficiency of the liquid raw material. The exhaust assembly 153 is a prior art and will not be described in detail here.

[0040] Reference Figure 2 and Figure 4 A rotating rod 22 is provided in the heating cylinder 2. One end of the rotating rod 22 away from the vertical plate 11 is coaxially fixed with the heating cylinder 2. When the heating cylinder 2 rotates, the rotating rod 22 is driven to rotate. One end of the rotating rod 22 close to the vertical plate 11 passes through the drying cylinder 3 and is rotatably connected to the drying cylinder 3. A section of the rotating rod 22 located at the drying cylinder 3 is provided with a plurality of supporting rods 221. The plurality of supporting rods 221 are evenly distributed along the circumference of the rotating rod 22. When the rotating rod 22 rotates, all the supporting rods 221 are driven to move synchronously.

[0041] Reference Figure 4 and Figure 5 The end of the support rod 221 away from the rotating rod 22 is provided with a scraper 23, the scraper 23 is arranged parallel to the rotating rod 22, and the end of the scraper 23 close to the support rod 221 is fixed with a sleeve 232, the sleeve 232 is sleeved on the outside of the support rod 221 and is slidably connected with the support rod 221 along the axial direction. Under the connection action of the sleeve 232, when the support rod 221 moves, the scraper 23 is driven to move through the sleeve 232. Further, in order to improve the connection strength between the rotating rod 22 and the scraper 23, a plurality of sleeves 232 are arranged along the length direction of the same scraper 23, and the rotating rod 22 is provided with support rods 221 corresponding to the sleeves 232, and the support rods 221 are inserted into the corresponding sleeves 232 and are slidably connected with the sleeves 232.

[0042] Reference Figure 4 and Figure 5 , when the sleeve 232 is at the position closest to the rotating rod 22, the side of the scraper 23 away from the rotating rod 22 contacts the inner wall of the drying cylinder 3 along the circumferential direction. The heating cylinder 2 rotates slowly, and the water in the liquid raw material in the drying cylinder 3 gradually evaporates. When the rotating rod 22 drives the scraper 23 to move through the sleeve 232, the scraper 23 scrapes the solid particles of ammonium butyl black medicine produced after the liquid raw material evaporates at the lower end of the drying cylinder 3. A push plate 231 is fixed on the side of the scraper 23 close to the support rod 221. The push plate 231 is vertically arranged with the scraper 23. When the scraper 23 scrapes the solid particles, the push plate 231 cooperates with the inner wall of the drying cylinder 3 to form a storage space, thereby reducing the probability of solid particles falling from the scraper 23.

[0043] Reference Figure 3 and Figure 5 A discharge port 30 is provided on one side of the drying cylinder 3. The discharge port 30 is located above the maximum width of the drying cylinder 3 in the vertical direction. The liquid level of the liquid raw material in the drying cylinder 3 is always lower than the discharge port 30 and the feed pipe 151. A blocking member is provided at the discharge port 30. The blocking member includes a sealing plate 321, a moving rod 322 and a moving block 323. The sealing plate 321 is located outside the drying cylinder 3 and directly faces the discharge port 30. The side of the sealing plate 321 close to the drying cylinder 3 is provided with an arc surface adapted to the outer circle of the drying cylinder 3. The upper end of the sealing plate 321 is hinged to the drying cylinder 3, and the hinge axis of the sealing plate 321 is parallel to the rotating rod 22.

[0044] Reference Figure 3 and Figure 5 An elastic member 324 is provided between the sealing plate 321 and the drying cylinder 3. The elastic member 324 is a torsion spring. One end of the torsion spring is fixedly connected to the sealing plate 321, and the other end is fixedly connected to the drying cylinder 3. The torsion spring is in a deformed state and pushes the sealing plate 321 to contact the drying cylinder 3, so that the sealing plate 321 blocks the discharge port 30, thereby preventing the steam in the drying cylinder 3 from entering between the heating cylinder 2 and the drying cylinder 3 from the discharge port 30.

[0045] Reference Figure 4 and Figure 5The moving block 323 is located in the drying cylinder 3 and is slidably connected to the drying cylinder 3 in the horizontal direction. The moving rod 322 is located between the sealing plate 321 and the moving block 323. One end of the moving rod 322 is hinged to the sealing plate 321, and the other end is hinged to the moving block 323. The drying cylinder 3 is provided with a groove for placing the moving rod 322. The connecting rod 333 is located in the groove, so as to avoid the scraper 23 when the scraper 23 rotates along the inner wall of the drying cylinder 3. When the sealing plate 321 is attached to the drying cylinder 3, the moving block 323 is at the position closest to the rotating rod 22. At this time, the moving block 323 is between the push plate 231 and the inner wall of the drying cylinder 3. The scraper 23 is provided with an avoidance groove 234 corresponding to the push plate 231. When the scraper 23 moves, the moving block 323 passes through the avoidance groove 234, and the moving block 323 and the scraper 23 do not interfere with each other.

[0046] Reference Figure 3 and Figure 5 The drying drum 3 is provided with a pusher for driving the scraper 23 to move along the axis of the support rod 221, and the pusher includes a moving plate 331, a push cylinder 332 and a connecting rod 333. The drying drum 3 and the vertical plate 11 (reference Figure 1 ) are provided with a transverse groove 111 in the transverse direction, and the connecting rod 333 passes through the transverse groove 111 and is slidably connected to the inner wall of the transverse groove 111 along the length direction of the transverse groove 111. Baffles 334 are fixed at both ends of the connecting rod 333, and the connecting rod 333 blocks the transverse groove 111 through the baffles 334, thereby preventing the steam in the drying cylinder 3 from leaking along the transverse groove 111.

[0047] Reference Figure 3 and Figure 5 The push cylinder 332 is installed on the side of the vertical plate 11 away from the heating cylinder 2, and the output end of the push cylinder 332 is fixedly connected to the connecting rod 333. When the push cylinder 332 is working, the connecting rod 333 is driven to move along the horizontal groove 111 through the output end. The moving plate 331 is located in the drying cylinder 3 and is fixedly connected to the connecting rod 333. When the connecting rod 333 moves, it drives the moving rod 322 to move. The side of the moving plate 331 away from the connecting rod 333 is provided with an arc groove 335 arranged with the rotating rod 22 as the center.

[0048] Reference Figure 5 and Figure 6 The sleeve 232 near the moving plate 331 is provided with an arc plate 24 adapted to the arc groove 335. The arc plate 24 is slidably connected to the sleeve 232 along the axis direction of the support rod 221. A straight rod 241 is fixedly provided on the side of the arc plate 24 away from the rotating rod 22. The straight rod 241 is arranged parallel to the support rod 221. When the arc plate 24 moves, the straight rod 241 is driven to move. The end of the push plate 231 away from the rotating rod 22 is provided with a top plate 242. The straight rod 241 passes through the push plate 231 and is fixedly connected to the top plate 242. When the straight rod 241 moves, it drives the top plate 242 to approach or move away from the push plate 231.

[0049] Reference Figure 5 and Figure 6 The sleeve 232 is provided with a limiting member 25, which includes a retaining ring 251, an elastic member 252 and an abutment block 253. The sleeve 232 is provided with an annular groove 233 along the axial direction. The retaining ring 251 is located in the annular groove 233 and is slidably connected to the sleeve 232 along the circumferential direction of the annular groove 233. The sleeve 232 limits the displacement of the retaining ring 251 along the length direction of the support rod 221 through the annular groove 233. The elastic member 252 is a spring, one end of which is fixedly connected to the retaining block 254, and the other end is fixedly connected to the sleeve 232. A stopper 254 is fixedly provided on the outer side of the retaining ring 251. When the arc plate 24 is in the position closest to the rotating rod 22, the elastic member 252 is in a natural state. At this time, the stopper 254 is in contact with the side of the arc plate 24 away from the rotating rod 22. The sleeve 232 limits the stopper 254 through the elastic member 252, so that the stopper 254 cooperates with the annular groove 233 to position the arc plate 24, thereby limiting the relative displacement of the arc plate 24 and the sleeve 232 along the axial direction of the support rod 221.

[0050] Reference Figure 2 and Figure 6 The abutment block 253 is fixedly arranged in the drying drum 3 and is aligned with the transverse groove 111 (reference Figure 3 ) are arranged in parallel, and a guide surface 255 is provided on the side of the stopper 254 facing away from the rotating rod 22. The guide surface 255 gradually approaches the axis from the outer circle of the drying cylinder 3 along the rotation direction of the rotating rod 22. Take the movement process of any scraper 23 as an example to illustrate. When the scraper 23 rotates along the inner wall of the drying cylinder 3, it approaches the discharge port 30 from the lower end of the drying cylinder 3. When the scraper 23 moves, it cooperates with the push plate 231 and the top plate 242 to drive the solid particles in the liquid raw material to move. When it is necessary to discharge the solid particles of ammonium butyl black medicine produced in the drying cylinder 3, the support rod 221 corresponding to the scraper 23 and the horizontal groove 111 (reference Figure 3 ) is parallel, the rotation of the heating cylinder 2 is stopped, at which time the lower end surface of the scraper 23 is flush with the side edge of the lower end of the discharge port 30, and the arc plate 24 corresponding to the scraper 23 is located in the arc groove 335 (reference Figure 5 )Inside.

[0051] Reference Figure 3 and Figure 6 At this time, the cylinder 332 is operated to drive the connecting rod 333 to move, so that the connecting rod 333 drives the moving plate 331 away from the rotating rod 22. When the moving rod 322 moves, it passes through the arc groove 335 (reference Figure 5 ) The inner wall exerts a force on the arc plate 24 away from the rotating rod 22 (reference Figure 4). At this time, the stopper 254 limits the arc plate 24 under the action of the elastic member 252, so that the arc plate 24 drives the sleeve 232 to approach the discharge port 30. When the sleeve 232 moves, it drives the push plate 231 to contact the moving block 323, and then drives the connecting rod 333 to move through the moving block 323. The connecting rod 333 pushes the sealing plate 321 to separate from the drying cylinder 3, so that the sealing plate 321 avoids the scraper 23 and the push plate 231.

[0052] Reference Figure 3 and Figure 6 , a placement box 34 is provided outside the drying drum 3, and the placement box 34 is connected to the discharge port 30 (reference Figure 5 ) is facing, the scraper 23 and the push plate 231 pass through the discharge port 30 (reference Figure 5 ) and then transport the solid particles to the placement box 34. When the sleeve 232 moves to the maximum displacement, the guide surface 255 of the stopper 254 contacts the abutment block, and when the sleeve 232 continues to move, the stopper 254 is pushed by the abutment block to separate from the arc plate 24, thereby releasing the restriction on the relative displacement between the arc plate 24 and the sleeve 232.

[0053] Reference Figure 3 and Figure 6 After the sleeve 232 moves to the maximum displacement, the arc plate 24 continues to move under the drive of the moving plate 331, so that the arc plate 24 and the sleeve 232 are relatively displaced along the length direction of the support rod 221. When the arc plate 24 moves, the top plate 242 is driven to separate from the push plate 231 through the straight rod 241. When the top plate 242 moves, the solid particles of butyl ammonium black medicine above the scraper 23 are pushed into the placement box 34, thereby reducing the probability of the solid particles of butyl ammonium black medicine staying on the scraper 23. After the pushing is completed, the moving plate 331 is reset and drives the arc plate 24 and the sleeve 232 close to the rotating rod 22, thereby resetting the sleeve 232 and the arc plate 24.

[0054] Reference Figure 3 and Figure 6 After the scraper 23 and the push plate 231 are reset, the sealing plate 321 blocks the discharge port 30 under the action of the elastic member 324. At this time, the heating cylinder 2 (reference Figure 2 ) continues to rotate, and at the same time dries the solid particles of butyl ammonium black medicine in the storage box and the liquid raw material in the drying cylinder 3. When the solid particles of butyl ammonium black medicine are dried, the steam in the drying cylinder 3 is not easy to interfere with it. While evaporating the raw material liquid, the solid particles of butyl ammonium black medicine that meet the drying requirements can be directly prepared. Furthermore, the drying cylinder 3 is provided with an opening connected to the exhaust pipe 152, so as to facilitate the discharge of the steam generated when the solid particles of butyl ammonium black medicine in the placement box 34 are dried.

[0055] Reference Figure 1 and Figure 4The support seat 1 is provided with a limit block 16, and the limit block 16 is slidably connected to the support seat 1 in the direction of approaching or moving away from the heating cylinder 2. In this embodiment, the horizontal movement of the limit block 16 is used as an example for explanation. In other embodiments, the limit block 16 can also move vertically. The support seat 1 is equipped with a positioning cylinder 17 for driving the limit block 16 to move. A plurality of fixed grooves 26 corresponding to the scraper 23 are provided on the outer side of the heating cylinder 2. When the positioning cylinder 17 pushes the limit block 16 to move, so that the limit block 16 is inserted into any fixed groove 26 and fits with the inner wall of the fixed groove 26, there is at least one scraper 23 facing the discharge port 30, so as to facilitate the arc plate 24 facing the arc groove 335. Through the cooperation between the limit block 16 and the fixed groove 26, it is convenient to accurately control the position of the scraper 23, which is conducive to improving the positioning accuracy of the scraper 23.

[0056] Reference Figure 1 and Figure 2 A discharge port 201 is provided on one side of the heating cylinder 2, and a sealing door 27 corresponding to the discharge port 201 is provided on the heating cylinder 2. When the sealing door 27 is located in the discharge port 201, it fits with the inner wall of the discharge port 201. At this time, the sealing door 27 blocks the discharge port 201, thereby reducing the probability of steam between the heating cylinder 2 and the drying cylinder 3 diffusing from the discharge port 201. An arc block 28 is provided at the end of the heating cylinder 2 close to the vertical plate 11, and a guide groove 202 adapted to the arc block 28 is provided on the heating cylinder 2. The arc block 28 is located in the guide groove 202 and is slidably connected to the heating cylinder 2 along the length direction of the guide groove 202.

[0057] Reference Figure 1 and Figure 7 The guide groove 202 is arranged in an arc shape with the rotation axis of the heating cylinder 2 as the center. A guide rod 29 is fixedly arranged on the side of the arc block 28 away from the axis of the heating cylinder 2. The extension line of the guide rod 29 to the arc block 28 coincides with the rotation axis of the heating cylinder 2. The sealing door 27 is fixedly provided with a connecting block 271 corresponding to the guide rod 29. The guide rod 29 passes through the connecting block 271 and is slidably connected to the connecting block 271. The connecting block 271 cooperates with the guide rod 29 to guide the sealing door 27, thereby facilitating the removal of the sealing door 27 from the discharge port 201 or the placement of the sealing door 27 into the discharge port 201.

[0058] Reference Figure 1 and Figure 7The guide rod 29 is fixed with a positioning ring 291, and the positioning ring 291 is provided with an external thread. The connecting block 271 is rotatably connected to a threaded tube 272 on one side close to the arc block 28, and the threaded tube 272 is provided with an internal thread adapted to the external thread. When the sealing door 27 is located in the discharge port 201, the threaded tube 272 is threadedly matched with the positioning ring 291, thereby restricting the sealing door 27, so that the heating cylinder 2 drives the sealing door 27 to move when it rotates. When it is necessary to take the solid particles of butyl ammonium black medicine, firstly disassemble the threaded tube 272 and the positioning ring 291, and after the sealing door 27 is moved out of the discharge port 201, the guide rod 29 and the arc block 28 are moved along the guide groove 202, and then the sealing door 27 avoids the discharge port 201, so as to pass through the discharge port 201 to collect the solid particles of butyl ammonium black medicine in the storage box.

[0059] The working principle of an intermittent drum dryer for preparing butyl ammonium black medicine in an embodiment of the present application is: the liquid raw material in the drying cylinder 3 is dried and heated by the heating cylinder 2, and the steam generated during the heating process is discharged through the exhaust pipe 152. During the rotation of the heating cylinder 2, the scraper 23 is driven by the rotating rod 22 to move along the inner wall of the drying cylinder 3. When solid particles of butyl ammonium black medicine are produced in the drying cylinder 3, the scraper 23 drives the solid particles of butyl ammonium black medicine in the drying cylinder 3 to move toward the discharge port 30. The heating cylinder 2 is operated to stop rotating, and the heating cylinder 2 is positioned by cooperating with the limit block 16 and the fixed groove 26. At this time, there is a scraper 23 facing the discharge port 30. The push cylinder 332 is operated to drive the connecting rod 333 away from the rotating rod 22. When the connecting rod 333 moves, it drives the arc plate 24 to move through the moving plate 331, so that the arc plate 24 drives the sleeve 232 away from the rotating rod 22 through the stop block 254. When the sleeve 232 moves, it drives the moving block 323 to move through the push plate 231, so that the moving block 323 pushes the sealing plate 321 through the connecting rod 333 to avoid the scraper 23.

[0060] After the stopper 254 contacts the abutment block 253, the arc plate 24 is avoided. At this time, the sleeve 232 moves to the farthest distance from the rotating rod 22, and the moving plate 331 continues to move toward the discharge port 30. Then, the arc plate 24 drives the top plate 242 to separate from the push plate 231 through the straight rod 241, so that the top plate 242 pushes the solid particles of butyl ammonium black medicine on the scraper 23 into the placement box 34. After the discharge is completed, the arc plate 24 and the sleeve 232 are reset. At this time, the sealing plate 321 blocks the discharge port 30 again under the action of the elastic member 324, thereby preventing the steam in the drying cylinder 3 from entering between the heating cylinder 2 and the drying cylinder 3. The heating cylinder 2 continues to heat, thereby drying the liquid raw material in the drying cylinder 3 and the solid particles of butyl ammonium black medicine in the placement box 34 at the same time. The steam generated during the drying of the liquid raw material is not easy to affect the solid particles in the placement box 34, thereby achieving the direct extraction of dry butyl ammonium black medicine while evaporating the raw material liquid.

[0061] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
