Description

Technical Field

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

[0002] In industrial production, vacuum drying technology is widely used in chemical, pharmaceutical and food industries because it can effectively reduce the boiling point of materials and prevent the oxidation of heat-sensitive components. The dryer is mainly composed of a heat source system, a vacuum system and a control system. The heat source system usually uses an electric heater or a fluid heat medium.

[0003] Currently, the working principle of a vacuum dryer is to use the low temperature and low pressure of a vacuum environment to place the items to be dried in a sealed container, and then use heating and exhaust to make the moisture evaporate and be removed quickly.

[0004] The above-mentioned existing technical solutions have the following drawbacks: Traditional vacuum dryers usually adopt a static chamber design, where the material is placed on a fixed platform for overall heating. Regardless of the size of the material, the heater needs to heat the entire vacuum chamber, resulting in energy waste. The excessively large ineffective chamber volume significantly prolongs the drying time and reduces production efficiency. Utility Model Content

[0005] The purpose of this invention is to provide a high-speed vacuum dryer to solve the problems existing in the prior art.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0007] A high-speed vacuum dryer includes a worktable and further includes:

[0008] A vacuum chamber is fixedly installed on the top of the workbench. The left and right walls inside the vacuum chamber are provided with grooves, and a heater is fixedly installed at the top inside the vacuum chamber.

[0009] The lifting mechanism is provided in two parts. One lifting mechanism is set in a groove. The two lifting mechanisms are symmetrical from left to right. The two lifting mechanisms are connected to the same fixed plate on the side that is close to each other. All four sides of the fixed plate are in contact with the inner wall of the vacuum chamber. The fixed plate is used to support the material to be dried.

[0010] The system includes two drive motors, both of which are located inside the worktable. One drive motor is used to drive a lifting mechanism for lifting.

[0011] By adopting the above technical solution, the lifting mechanism is set inside the vacuum chamber, and the heater releases heat at the top of the vacuum chamber. The material to be dried is placed on the fixed plate, which divides the vacuum chamber into upper and lower chambers. According to the height of the material, the height of the fixed plate in the vacuum chamber is adjusted by the lifting mechanism, so that the material is in a relatively small drying space. Moreover, by taking advantage of the characteristic of hot air rising, the heat emitted by the heater is more concentrated in the upper chamber, thereby achieving rapid drying of the material.

[0012] In a further embodiment, the lifting mechanism includes:

[0013] The guide rail unit includes a first guide rail and a second guide rail, which are mirror images of each other. The track surfaces of the first and second guide rails are close to each other. The first guide rail is fixedly installed in the front part of the groove, and the second guide rail is fixedly installed in the rear part of the groove.

[0014] The slider has its two ends slidably mounted in the grooves of the first guide rail and the second guide rail, respectively, and the top of the slider has an internal threaded hole that runs through it from top to bottom.

[0015] The screw is inserted into the internal threaded hole. A first bearing is fixedly installed at the top of the groove, and a second bearing is fixedly installed at the bottom of the groove. The top of the screw is fixedly installed in the first bearing, and the bottom of the screw passes through and extends to the bottom of the second bearing. The bottom of the screw passes through the worktable and is connected to a drive motor via a coupling.

[0016] In a further embodiment, the slider has integrally formed protrusions on both the left and right sides. The side of the protrusion closest to the fixing plate is fixedly connected to the fixing plate, and the side of the protrusion away from the fixing plate is in contact with the inner wall of the vacuum chamber. The left and right widths of the protrusion are the same as the side wall widths of the first guide rail. The front side of the protrusion is in contact with the rear side of the first guide rail, and the rear side of the protrusion is in contact with the front side of the second guide rail.

[0017] By adopting the above technical solution, two drive motors synchronously drive their corresponding screws to rotate forward or in reverse, thereby causing the fixed plate to move up and down in the slide. The distance the fixed plate moves up or down can be adjusted by controlling the working time of the drive motors.

[0018] In a further embodiment, a vacuum pump is provided at intervals on one side of the workbench, the vacuum pump being used to provide a vacuum environment inside the vacuum chamber.

[0019] In a further embodiment, a sealed door is hinged to the front side of the vacuum chamber.

[0020] In a further embodiment, one end of a connecting rod is fixedly installed on the top of the vacuum chamber, and a control panel is fixedly installed on the other end of the connecting rod.

[0021] In summary, this utility model has the following beneficial effects:

[0022] 1. The heating element is installed inside the vacuum chamber via a lifting mechanism. Heater releases heat at the top of the vacuum chamber. The material to be dried is placed on a fixed plate, which divides the vacuum chamber into upper and lower chambers. The height of the fixed plate inside the vacuum chamber is adjusted according to the height of the material, so that the material is in a relatively small drying space. Utilizing the characteristic of hot air rising, the heat emitted by the heater is more concentrated in the upper chamber, which can achieve the effect of quickly drying the material.

[0023] 2. By providing integrated protrusions on both the left and right sides of the slider, the upper chamber of the dryer achieves a better sealing effect, better concentrating the drying heat in the upper chamber, thus achieving high-speed drying and energy-saving effects.

[0031] Example 1:

[0032] like Figures 1-4 As shown, a high-speed vacuum dryer includes a worktable 1, a vacuum chamber 2, a lifting mechanism 3, and a drive motor 5. The vacuum chamber 2 is fixedly installed on the top of the worktable 1. Both the left and right ends of the top of the worktable 1 are provided with vertically penetrating clearance openings. The left and right walls inside the vacuum chamber 2 are provided with grooves. A heater 11 is fixedly installed at the top of the vacuum chamber 2. There are two lifting mechanisms 3, one in each groove, and the two lifting mechanisms 3 are symmetrically arranged. The two lifting mechanisms 3 are connected to the same fixing plate 4 on the side closest to each other. All four sides of the fixing plate 4 are in contact with the inner wall of the vacuum chamber 2. The fixing plate 4 is used to support the material to be dried. There are two drive motors 5, both of which are located inside the worktable 1. One drive motor 5 is used to drive one lifting mechanism 3 to lift.

[0033] The lifting mechanism 3 includes a guide rail unit 31, a slider 32, and a screw 33. The guide rail unit 31 includes a first guide rail 311 and a second guide rail 312, which are mirror images of each other. The track surfaces of the first guide rail 311 and the second guide rail 312 are close to each other. The first guide rail 311 is fixedly installed in the front part of the groove, and the second guide rail 312 is fixedly installed in the rear part of the groove. The two ends of the slider 32 are slidably installed in the grooves of the first guide rail 311 and the second guide rail 312, respectively. The top of the slider 32 has a through-hole internal threaded hole, and the screw 33 passes through the internal threaded hole. The top of the groove has an upward-facing first mounting hole, in which a first bearing is fixedly installed. The bottom of the groove has a downward-facing second mounting hole, in which a second bearing is fixedly installed. The top of the screw 33 is fixedly installed in the first bearing, and the bottom of the screw 33 passes through and extends to the bottom of the second bearing. The bottom of the screw 33 passes through a clearance opening at the top of the worktable 1 and is connected to a coupling 9 for transmission. The drive motor 5; The slider 32 has integrally formed protrusions on both its left and right sides. The side of the protrusion closest to the fixed plate 4 is fixedly connected to the fixed plate 4, and the side of the protrusion facing away from the fixed plate 4 is flush with the inner wall of the vacuum chamber 2. The left and right widths of the protrusions are the same as the side wall widths of the first guide rail 311. The front side of the protrusion is flush with the rear side of the first guide rail 311, and the rear side of the protrusion is flush with the front side of the second guide rail 312. Vacuum pumps 6 are spaced apart on the rear side of the worktable 1. The suction port of the vacuum pump 6 is connected to one end of a pipe, and the other end of the pipe... One end is connected to the interior of vacuum chamber 2, and vacuum pump 6 is used to provide a vacuum environment inside vacuum chamber 2; a through mounting port is provided on the front side of vacuum chamber 2, and a sealed door 7 is provided in the mounting port. The sealed door 7 includes a first door and a second door. The first door and the second door are symmetrically arranged in the mounting port. The side of the first door and the second door that are opposite to each other is hinged and fixed to vacuum chamber 7; one end of connecting rod 10 is fixedly installed on the top right end of vacuum chamber 2, and the other end of connecting rod 10 is fixedly installed with control panel 8.

[0034] Specific implementation process: First, open the sealed door 7 hinged at the front of the vacuum chamber 1. Adjust the lifting height of the fixed plate 4 according to the height of the material to be dried, so that the material is in a relatively small drying space. Start the two drive motors 5, which are set inside the workbench 1 and each corresponds to a lifting mechanism 3, simultaneously. The drive motors 5 drive the screw 33 to rotate forward or backward through the coupling 9. The screw 33 rotates in the internal threaded hole, causing the slider 32 to slide up and down in the first guide rail 311 and the second guide rail 312. Since the slider 32 is fixedly connected to the fixed plate 4, it drives the fixed plate 4 to move up and down. By controlling the working time of the drive motor 5, adjust the distance the fixed plate 4 moves up or down. Then, place the material to be dried on the fixed plate 4, and then close the sealed door. Seal the door 7, start the vacuum pump 6, and the vacuum pump 6 quickly extracts the air from the vacuum chamber 2 to create a vacuum environment. Then, turn on the heater 11, which releases heat. Since the fixed plate 4 divides the vacuum chamber 2 into upper and lower chambers, the heat emitted by the heater 11 is more concentrated in the upper chamber due to the rising properties of hot air, surrounding the material and rapidly heating it. This causes the moisture in the material to evaporate quickly. The water vapor produced by evaporation can escape from the material more quickly in a vacuum environment. Throughout the drying process, the operator can monitor and adjust the drying parameters in real time through the control panel 8 fixedly installed on the connecting rod 10 at the top of the vacuum chamber 2 to ensure the best drying effect and ultimately achieve high-speed drying of the material.
