Description

Technical Field

[0001] This utility model relates to the field of vacuum dryer technology, and in particular to a rotary vacuum dryer. Background Technology

[0002] Agricultural microbial agents are functional microbial agents and soil-borne disease control agents developed using advanced biotechnology to address the situation of expanding crop cultivation and seedling transplantation areas, increasing continuous cropping, and increasingly serious crop diseases and pests. When using some microbial agents, a vacuum dryer is required to dry them to ensure stable effects.

[0003] As existing vacuum dryers are used for a longer period of time, the moisture absorption plates will absorb a large amount of moisture. When the moisture content reaches a certain level, the water absorption effect of the moisture absorption plates will be greatly reduced, and they need to be replaced. The disassembly and assembly of the moisture absorption plates during replacement is relatively troublesome, which reduces the efficiency of the work. Summary of the Invention

[0004] In view of this, the present invention provides a rotary vacuum dryer, the main technical problem to be solved is: the problem of the inconvenience of disassembling and assembling the moisture-absorbing plate in the rotary vacuum dryer.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: a rotary vacuum dryer, comprising a shell, a drying cylinder movably connected to the inner side of the shell, a sealing cover threadedly connected to the upper part of the outer side of the shell, a vacuum pumping device fixedly connected to the lower part of the shell, a moisture-absorbing plate movably connected inside the vacuum pumping device, a fixing block fixedly connected to the outer side of the vacuum pumping device, the moisture-absorbing plate including a pull plate movably connected inside the vacuum pumping device, a sealing sleeve fixedly connected to the outer side of the pull plate, a fixing sleeve fixedly connected to the left side of the pull plate, a plate body fixedly connected to the inner side of the fixing sleeve, a locking block movably connected inside the pull plate, a spring fixedly connected between the pull plate and the locking block, a connecting frame fixedly connected to the lower part of the locking block, and a handle fixedly connected to the right end of the connecting frame.

[0006] By adopting the above technical solution, the handle is pushed downwards, which in turn drives the connecting frame to move the locking block downwards, allowing the locking block to leave the slot and the moisture-absorbing plate to be extracted from the vacuum pump. This facilitates the replacement of the moisture-absorbing plate. After the new plate is installed, the moisture-absorbing plate is inserted into the vacuum pump. Through repeated insertion, the top of the locking block contacts the fixing block, and the locking block is retracted into the pull plate by compression, allowing the moisture-absorbing plate to be fully inserted into the vacuum pump. After full insertion, the locking block is locked into the slot by the spring, thus fixing the moisture-absorbing plate and facilitating quick assembly and disassembly of the moisture-absorbing plate.

[0007] As a further description of the above technical solution: the outer shell includes a housing, the inner side of which is provided with a rotating groove, a heating wire is fixedly connected inside the housing, the lower part of the housing is provided with a through hole, and the middle of the lower part of the housing is provided with a fixing hole.

[0008] By adopting the above technical solution, the heating wire is energized to generate heat, which is then transferred to the cylinder through heat conduction, allowing the microbial agents inside to be dried under the influence of temperature.

[0009] As a further description of the above technical solution: the drying cylinder includes a cylinder body movably connected to the inner side of the shell, the outer side of the cylinder body is provided with a through groove, a motor is fixedly connected to the lower part of the inner side of the shell, the output end of the motor is fixedly connected to a rotating shaft, and the top of the rotating shaft is fixedly connected to the cylinder body.

[0010] By adopting the above technical solution, the through slot is used for air passage, and the rotating shaft can be driven to rotate the cylinder by starting the motor.

[0011] As a further description of the above technical solution: the sealing cover includes a cover body that is threadedly connected to the upper part of the outer side of the shell, a connecting post is fixedly connected to the lower part of the cover body, and a stirring rod is fixedly connected to the outer side of the connecting post.

[0012] By adopting the above technical solution, starting the motor enables the rotating shaft to drive the outer cylinder to rotate, which in turn drives the microbial agent in the inner cylinder to rotate relative to the stirring rod, so that the stirring rod can stir the microbial agent and ensure that it can be dried more thoroughly.

[0013] As a further description of the above technical solution: the vacuum pumping device includes a fixed shell fixedly connected to the lower part of the housing, a limit block fixedly connected to the inner side of the fixed shell, a support column fixedly connected to the lower part of the fixed shell, a pump fixedly connected to the lower part of the interior of the fixed shell, an exhaust pipe fixedly connected to the lower part of the pump, an air suction pipe fixedly connected to the top of the pump, and an air suction cylinder fixedly connected to the upper part of the outer side of the air suction pipe.

[0014] By adopting the above technical solution, the air in the inner cylinder can enter the through hole through the through groove by starting the air pump, and then enter the air suction cylinder through the moisture absorption plate. After that, it can be discharged from the exhaust pipe through the air suction pipe, so that the air inside the dryer can be discharged quickly, and the moisture in the microbial agent can be evaporated quickly, which can accelerate the drying efficiency.

[0015] As a further description of the above technical solution: the fixing block includes a block body fixedly connected to the outside of the fixing shell, and the lower part of the block body is provided with a slot.

[0016] By adopting the above technical solution, the card slot is used for inserting the card block.

[0017] By employing the above technical solution, the rotary vacuum dryer of this utility model has at least the following beneficial effects:

[0018] Compared with existing technologies, this rotary vacuum dryer, by incorporating a moisture-absorbing plate and a fixing block, facilitates the assembly and disassembly of the moisture-absorbing plate. By pushing the handle downwards, the connecting frame is moved downwards, causing the locking block to disengage from the slot. This allows the moisture-absorbing plate to be extracted from the vacuum pump, facilitating the replacement of the moisture-absorbing plate. After replacing the plate, the moisture-absorbing plate is inserted into the vacuum pump. Through repeated insertion, the top of the locking block contacts the fixing block, and the locking block retracts into the pull plate, allowing the moisture-absorbing plate to be fully inserted into the vacuum pump. Once fully inserted, the locking block engages with the slot under the action of a spring, thus fixing the moisture-absorbing plate in place. This facilitates quick assembly and disassembly of the moisture-absorbing plate. Attached Figure Description

[0027] To make the technical problems, technical solutions, and beneficial effects to be solved by this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and are not intended to limit the scope of this application.

[0028] Reference Figures 1-6 This utility model provides a rotary vacuum dryer, including a shell 1, a drying cylinder 2 movably connected to the inner side of the shell 1, a sealing cover 3 threadedly connected to the upper outer side of the shell 1, a vacuum pumping device 4 fixedly connected to the lower part of the shell 1, a moisture-absorbing plate 5 movably connected inside the vacuum pumping device 4, and a fixing block 6 fixedly connected to the outer side of the vacuum pumping device 4. The moisture-absorbing plate 5 includes a pull plate 501 movably connected inside the vacuum pumping device 4, and a sealing sleeve 502 fixedly connected to the outer side of the pull plate 501. The sealing sleeve 502 is used to secure the shell 4. The sealing between 01 and pull plate 501 is better. A fixing sleeve 503 is fixedly connected to the left side of pull plate 501. A plate body 504 is fixedly connected to the inner side of fixing sleeve 503. A locking block 505 is movably connected inside pull plate 501. The locking block 505 can be raised and lowered inside pull plate 501. A spring 508 is fixedly connected between pull plate 501 and locking block 505. A connecting frame 506 is fixedly connected to the lower part of locking block 505. The connecting frame 506 can be raised and lowered inside pull plate 501. A handle 507 is fixedly connected to the right end of connecting frame 506.

[0029] In use, by pushing the handle 507 downwards, the connecting bracket 506 is moved so that the locking block 505 can move downwards, allowing the locking block 505 to leave the slot 602. This allows the moisture-absorbing plate 5 to be pulled out from inside the vacuum pumping device 4, facilitating the replacement of the moisture-absorbing plate 504. After replacing the new plate 504, the moisture-absorbing plate 5 is inserted into the vacuum pumping device 4. Through repeated insertion, the top of the locking block 505 can contact the fixing block 6, and by squeezing, the locking block 505 can retract into the pull plate 501, allowing the moisture-absorbing plate 5 to be fully inserted into the vacuum pumping device 4. After full insertion, under the action of the spring 508, the locking block 505 can be locked into the slot 602, thus fixing the moisture-absorbing plate 5 and facilitating quick assembly and disassembly of the moisture-absorbing plate 5.

[0030] Furthermore, such as Figure 3 As shown, the outer shell 1 includes a shell 101. The inner side of the shell 101 is provided with a rotating groove 102 for the rotation of the drying cylinder 2. A heating wire 103 is fixedly connected inside the shell 101. The lower part of the shell 101 is provided with a through hole 104 for air to pass through. The middle of the lower part of the shell 101 is provided with a fixing hole 105 for fixing the motor 203. By energizing the heating wire 103, it can generate heat. The heat is transferred to the cylinder 201 through heat conduction, so that the microbial agent inside can be dried under the action of temperature.

[0031] Furthermore, such as Figure 4 As shown, the drying cylinder 2 includes a cylinder 201 movably connected to the inside of the housing 101. A through groove 202 is provided on the outside of the cylinder 201 for air to pass through. A motor 203 is fixedly connected to the lower part inside the housing 101. A rotating shaft 204 is fixedly connected to the output end of the motor 203. The top of the rotating shaft 204 is fixedly connected to the cylinder 201. By starting the motor 203, the rotating shaft 204 can drive the cylinder 201 to rotate.

[0032] Furthermore, such as Figure 1 As shown, the sealing cover 3 includes a cover body 301 threadedly connected to the upper part of the outer side of the housing 101. A connecting post 302 is fixedly connected to the lower part of the cover body 301, and a stirring rod 303 is fixedly connected to the outer side of the connecting post 302. By starting the motor 203, the rotating shaft 204 can drive the cylinder 201 to rotate, which in turn can drive the microbial agent in the cylinder 201 to rotate relative to the stirring rod 303, so that the stirring rod 303 can stir the microbial agent and ensure that it can be dried more thoroughly.

[0033] Furthermore, such as Figure 5As shown, the vacuum pumping device 4 includes a fixed shell 401 fixedly connected to the lower part of the housing 101. A limiting block 402 is fixedly connected to the inner side of the fixed shell 401. The limiting block 402 is used to limit the position of the moisture-absorbing plate 5 to prevent the moisture-absorbing plate 5 from being inserted too deeply. A support column 404 is fixedly connected to the lower part of the fixed shell 401. A vacuum pump 406 is fixedly connected to the lower part of the fixed shell 401. An exhaust pipe 407 is fixedly connected to the lower part of the vacuum pump 406. An air suction pipe 405 is fixedly connected to the top of the vacuum pump 406. An air suction cylinder 403 is fixedly connected to the upper part of the outer side of the air suction pipe 405.

[0034] By activating the air pump 406, air in the cylinder 201 can enter the through hole 104 through the through groove 202, and then enter the suction cylinder 403 through the moisture absorption plate 5. After that, it is discharged from the exhaust pipe 407 through the suction pipe 405, so that the air inside the dryer can be discharged quickly, thereby allowing the moisture in the microbial agent to be evaporated quickly, which facilitates the acceleration of drying efficiency.

[0035] Furthermore, the fixing block 6 includes a block body 601 fixedly connected to the outside of the fixing shell 401. The lower part of the block body 601 is provided with a slot 602 for the insertion of the locking block 505.

[0036] Working principle: During use, the microbial agent is placed in the cylinder 201, and then the sealing cover 3 is closed for drying. Before drying, the heating wire 103 is energized, generating heat. This heat is conducted to the cylinder 201, allowing the microbial agent inside to dry under the influence of temperature. Simultaneously, the vacuum pump 406 is activated, allowing air in the cylinder 201 to enter the through hole 104 through the through groove 202, and then through the moisture absorption plate 5 into the suction cylinder 403. The air is then discharged through the suction pipe 405 and the exhaust pipe 407, allowing the air inside the dryer to be quickly expelled. This facilitates the rapid evaporation of moisture from the microbial agent, accelerating the drying process. The evaporated water vapor is continuously absorbed by the plate 504 under the action of the vacuum pump 4. Over time, the plate 504 absorbs a large amount of moisture. By pushing the handle 507 downwards, the connecting frame 506 is moved, causing the locking block 505 to move downwards. This allows the locking block 505 to leave the slot 602, and the moisture-absorbing plate 5 can be pulled out from the inside of the vacuum pump 4. This facilitates the replacement of the moisture-absorbing plate 504. After replacing the plate 504, the moisture-absorbing plate 5 is inserted into the vacuum pump 4. Through repeated insertion, the top of the locking block 505 contacts the fixing block 6, and by squeezing, the locking block 505 retracts into the pull plate 501, allowing the moisture-absorbing plate 5 to be fully inserted into the vacuum pump 4. After full insertion, the locking block 505 is locked into the slot 602 by the action of the spring 508, thus fixing the moisture-absorbing plate 5 in place and facilitating quick assembly and disassembly of the moisture-absorbing plate 5.

[0037] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model.
