Description

Technical Field

[0001] The utility model relates to a vacuum drying device with a drainage function, belonging to the technical field of drying devices. Background Art

[0002] A dryer is a mechanical device that uses heat energy to reduce the moisture content of materials. It is used to dry objects. The dryer vaporizes the moisture in the material by heating to obtain solid materials with a specified moisture content. The purpose of drying is to meet the needs of material use or further processing. According to the operating pressure, dryers are divided into two categories: atmospheric pressure dryers and vacuum dryers. According to the operating pressure, they can be divided into atmospheric pressure and reduced pressure. There are many types of dryers, including vacuum dryers.

[0003] A Chinese public patent (publication number: CN 215373174 U) discloses a vacuum drying device with drainage function, including a vacuum drying tank, a column and a pumping device; the vacuum drying tank includes a tank body, which is used to vacuum dry wet materials inside the tank body; an ear seat is provided on the outer wall of the tank body, the ear seat is connected to the column, and the lower end of the column is located on the foundation, so that a space for installing the pumping device is reserved at the bottom of the tank body; the pumping device is connected to the diversion port at the bottom of the tank body to pump out the accumulated water at the bottom of the tank body. The utility model can pump out the moisture at the bottom of the tank when the vacuum pump is in the working state, that is, when the vacuum drying tank is in a slightly negative pressure state, so as to discharge the water vapor as soon as possible and improve the drying efficiency;

[0004] However, when taking out materials, the device can only rely on removing the cover plate and taking out the materials placed in the tank body. The materials near the bottom of the tank body cannot be easily taken out due to the depth of the tank body. At the same time, since the trays of the above-mentioned device are all at the same vertical angle, the moisture of the objects in the top tray during drying will fall into the bottom tray in turn, so that after the objects in the top tray are dried, the objects in the bottom tray may still be in a wet state, resulting in the inability to synchronously dry the materials in the drying box, thereby affecting the overall drying efficiency of the materials and being inconvenient for staff to use.

[0005] Therefore, a vacuum drying device with drainage function is proposed. Utility Model Content

[0006] In view of this, the utility model provides a vacuum drying device with a drainage function to solve or alleviate the technical problems existing in the prior art and at least provide a beneficial choice.

[0007] The technical solution of the utility model is implemented as follows: a vacuum drying device with drainage function, comprising a drying box, a card plate is clamped on the outside of the drying box, a top plate is arranged on the top of the drying box, and a vacuum exhaust valve is fixedly installed on the top of the top plate;

[0008] A discharging mechanism is provided at the bottom of the drying box, and the discharging mechanism includes a motor, and the motor is fixedly installed at the bottom of the drying box. A screw is fixedly connected to the output end of the motor, and an internally threaded sleeve is threadedly connected to the surface of the screw. Electric telescopic rods are fixedly installed around the outer side of the internally threaded sleeve, and the twelve electric telescopic rods are shortened from top to bottom. Water seepage boxes are fixedly installed on the outer sides of the twelve electric telescopic rods, and materials are placed in the inner cavities of the twelve water seepage boxes. The bottom of the top plate is fixedly installed on the top of the internally threaded sleeve.

[0009] Further preferably, a sealing ring is fixedly mounted on the bottom of the top plate, and the sealing ring is clamped in the inner surface of the drying box.

[0010] Further preferably, a waterproof cover is provided on the outer side of the motor, and the waterproof cover is fixedly installed at the middle end of the bottom of the drying box.

[0011] Further preferably, limit rods are fixedly installed on both left and right sides of the bottom of the inner cavity of the drying box, and the limit rods are movably connected to the inner surfaces of the left and right sides of the internal threaded sleeve rod.

[0012] Further preferably, a conical guide groove is provided at the bottom of the inner cavity of the drying box, a drainage groove is provided at the middle end of the bottom of the inner cavity of the drying box, and a one-way drainage valve is fixedly installed at the bottom of the drying box.

[0013] Further preferably, support rods are fixedly installed at the bottom of the drying box, and anchor bolts are arranged at the bottoms of the eight support rods, and the anchor bolts are threadedly connected to the ground.

[0014] Further preferably, a humidity sensor is fixedly mounted on the rear side of the bottom of the top plate, and a humidity sensing panel is fixedly mounted on the left side of the top of the card board.

[0015] Further preferably, a temperature sensor is fixedly mounted on the front side of the bottom of the top plate, and a temperature display panel is fixedly mounted on the right side of the top of the card board.

[0016] The embodiment of the utility model has the following advantages due to the adoption of the above technical solution:

[0017] 1. The utility model provides a discharging mechanism. First, the electric telescopic rod is retracted to retract the water seepage box inward so that it is within the range of the top discharging port of the drying box. Then, the motor outputs and the lead screw rotates. At this time, the internal threaded sleeve moves upward due to the rotation of the lead screw. At this time, the internal threaded sleeve drives the electric telescopic rod to move upward synchronously. With the movement of the electric telescopic rod, the water seepage box moves upward synchronously and drives the dried materials inside it to move out of the inner cavity of the drying box, thereby achieving the purpose of facilitating material retrieval. At the same time, due to the extensibility of the electric telescopic rod, the water seepage box will not be in the same vertical direction, which effectively prevents the moisture in the top water seepage box from falling into the bottom water seepage box due to gravity, so that the materials to be dried inside the two cannot be dried synchronously, affecting the normal drying efficiency.

[0018] Second, the utility model can seal the connection between the top plate and the drying box by setting a sealing ring to avoid gas penetration at the connection, so that the drying box cannot form a vacuum environment. By setting a waterproof cover, the motor can be protected to avoid moisture entering the inside of the motor when the moisture in the drying box is discharged, causing damage to the components in the motor. By setting a limit rod, the movement of the internal threaded sleeve rod can be limited to avoid it rotating synchronously with the screw rod, thereby affecting the normal material discharge work. By setting a conical guide groove, a drainage groove and a one-way drainage valve, the moisture in the inner cavity of the drying box can be discharged to avoid the damage caused by the material. The moisture discharged when the material is dried accumulates in the inner cavity of the drying box, thus affecting the drying work of the material. By setting the support rod, the drying box can be supported, and the anchor bolts set at the bottom can be used to stabilize the entire equipment to avoid the equipment from tipping over due to collisions from external factors. By setting the humidity sensor and the humidity sensing panel, the humidity in the inner cavity of the drying box can be easily detected, so as to understand the drying condition of the material. By setting the temperature sensor and the temperature display panel, the temperature in the inner cavity of the drying box can be monitored in real time to avoid the temperature being too high or too low, which may cause the material to fail to dry normally.

[0019] The above summary is for the purpose of description only and is not intended to be limiting in any way.

[0027] In the following, only some exemplary embodiments are briefly described. As those skilled in the art will appreciate, the described embodiments may be modified in various ways without departing from the spirit or scope of the present invention. Therefore, the drawings and descriptions are considered to be exemplary and non-restrictive in nature.

[0028] The embodiments of the present utility model are described in detail below with reference to the accompanying drawings.

[0029] Example 1

[0030] like Figure 1-5 As shown, the embodiment of the utility model provides a vacuum drying device with drainage function, including a drying box 1, a clamping plate 5 is clamped on the outside of the drying box 1, a top plate 3 is arranged on the top of the drying box 1, and a vacuum exhaust valve 4 is fixedly installed on the top of the top plate 3;

[0031] A discharging mechanism 2 is provided at the bottom of the drying box 1, and the discharging mechanism 2 includes a motor 201, which is fixedly installed at the bottom of the drying box 1. A screw rod 202 is fixedly connected to the output end of the motor 201, and an internal threaded sleeve rod 203 is threadedly connected to the surface of the screw rod 202. Electric telescopic rods 204 are fixedly installed around the outer side of the internal threaded sleeve rod 203. The twelve electric telescopic rods 204 become shorter from top to bottom. Water seepage boxes 205 are fixedly installed on the outer sides of the twelve electric telescopic rods 204. Materials are placed in the inner cavities of the twelve water seepage boxes 205. The bottom of the top plate 3 is fixedly installed on the top of the internal threaded sleeve rod 203.

[0032] By setting the discharging mechanism 2, firstly, the electric telescopic rod 204 is contracted, so that the seepage box 205 is contracted inwardly, so that it is within the range of the top discharge port of the drying box 1, and then the screw rod 202 is rotated through the output of the motor 201. At this time, the internal threaded sleeve rod 203 moves upward due to the rotation of the screw rod 202. At this time, the internal threaded sleeve rod 203 drives the electric telescopic rod 204 to move upward synchronously. With the movement of the electric telescopic rod 204, the seepage box 205 moves upward synchronously, and drives the dried materials inside it to move out of the inner cavity of the drying box 1, so as to achieve the purpose of facilitating material removal. At the same time, due to the extensibility of the electric telescopic rod 204, the seepage box 205 will not be in the same vertical direction directly, which effectively avoids the moisture in the top seepage box 205 from falling into the bottom seepage box 205 due to the influence of gravity, so that the materials to be dried inside the two cannot be dried synchronously, affecting the normal drying efficiency.

[0033] Example 2

[0034] In one embodiment, a sealing ring 208 is fixedly installed at the bottom of the top plate 3, and the sealing ring 208 is clamped in the inner surface of the drying box 1. A waterproof cover 207 is provided on the outside of the motor 201, and the waterproof cover 207 is fixedly installed at the middle end of the bottom of the drying box 1. Limit rods 206 are fixedly installed on the left and right sides of the bottom of the inner cavity of the drying box 1, and the limit rods 206 are movably connected to the inner surfaces of the left and right sides of the internal threaded sleeve 203. A conical guide groove 11 is opened at the bottom of the inner cavity of the drying box 1, and a drainage groove 12 is opened at the middle end of the bottom of the inner cavity of the drying box 1. A one-way drainage valve 13 is fixedly installed at the bottom of the drying box 1, and support rods 6 are fixedly installed at the bottom of the drying box 1. The bottoms of the eight support rods 6 are provided with anchor bolts, and the anchor bolts are threadedly connected to the ground. A humidity sensor 7 is fixedly installed on the rear side of the bottom of the top plate 3, a humidity sensing panel 8 is fixedly installed on the left side of the top of the card board 5, a temperature sensor 9 is fixedly installed on the front side of the bottom of the top plate 3, and a temperature display panel 10 is fixedly installed on the right side of the top of the card board 5.

[0035] By setting a sealing ring 208, the connection between the top plate 3 and the drying box 1 can be sealed to avoid gas penetration at the connection, so that the drying box 1 cannot form a vacuum environment. By setting a waterproof cover 207, the motor 201 can be protected to avoid moisture entering the interior of the motor 201 when the moisture in the drying box 1 is discharged, causing damage to the components in the motor 201. By setting a limiting rod 206, the movement of the internal threaded sleeve rod 203 can be limited to avoid it rotating synchronously with the screw rod 202, thereby affecting the normal material discharge work. By setting a conical guide groove 11, a drainage groove 12 and a one-way drainage valve 13, the moisture in the inner cavity of the drying box 1 can be discharged. The moisture discharged during material drying can be discharged to avoid accumulation of moisture discharged during material drying in the inner cavity of the drying box 1, thereby affecting the drying work of the material. By setting the support rod 6, the drying box 1 can be supported, and the anchor bolts set at the bottom of the drying box can be used to stabilize the entire device to avoid the device from tipping over due to collision with external factors. By setting the humidity sensor 7 and the humidity sensing panel 8, the humidity in the inner cavity of the drying box 1 can be conveniently detected to facilitate understanding of the drying condition of the material. By setting the temperature sensor 9 and the temperature display panel 10, the temperature in the inner cavity of the drying box 1 can be conveniently monitored in real time to avoid excessively high or low temperature, which may result in the material being unable to dry normally.

[0036] When the utility model is working: first, the wet material is placed in the water seepage box 205, and then the screw rod 202 is rotated through the output of the motor 201, and drives the internal threaded sleeve rod 203 to move downward along the thread on the surface of the screw rod 202. At this time, the internal threaded sleeve rod 203 drives the electric telescopic rod 204, the water seepage box 205 and the top plate 3 to move downward synchronously. After the sealing ring 208 is clamped to the inner surface of the top of the drying box 1, the gas in the drying box 1 is discharged through the vacuum exhaust valve 4 to make it in a vacuum environment. Then the electric telescopic rod 204 is extended outward, and it becomes longer from top to bottom, so that the water seepage box 205 will not be in the same vertical position. Then the material is dried by the drying box 1. The material is dried and the moisture in the drying process is discharged from the inner cavity of the drying box 1 through the vacuum exhaust valve 4, and the moisture flowing from the material flows to the bottom of the drying box 1 through the seepage box box 205, and is discharged through the guidance of the conical guide groove 11, through the cooperation of the drainage groove 12 and the one-way drainage valve 13, thereby completing the drying of the material. When the material is dried, the electric telescopic rod 204 contracts inward, and then the motor 201 outputs again and causes the screw rod 202 to rotate in the opposite direction. At this time, the internal threaded sleeve rod 203 moves upward along the thread on the surface of the screw rod 202, and drives the electric telescopic rod 204, the seepage box box 205 and the top plate 3 to move out of the inner cavity of the drying box 1, completing the material discharge work.

[0037] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can easily think of various changes or substitutions within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
