For the purpose of making the objects, technical solutions and advantages of the present invention more apparent, embodiments of the present invention will be described in further detail below with reference to the accompanying drawings.
Referring to fig. 1 and 2, the embodiment discloses an experimental equipment constant temperature drying oven, which comprises a drying oven body 100, wherein a plurality of accommodating cavities 110 are arranged on the drying oven body 100, and a drying chamber 200 can be placed in each accommodating cavity 110. An air outlet 111 is provided in the accommodation chamber 110, and a drying system is provided in the drying box body 100, so that dry air can be output into the drying chamber 200 through the air outlet 111 of each accommodation chamber 110. The air outlet 111 of the accommodating chamber 110 is located on the sidewall of the accommodating chamber 110. A sliding portion 120 is provided in the accommodating chamber 110, and the sliding portion 120 is in sliding contact with a sidewall of the accommodating chamber 110. When the sliding part 120 is positioned at the outermost end of the accommodating chamber 110, the sliding part 120 can block the air outlet 111, and the sliding part 120 can form a seal with the outer end edge of the accommodating chamber 110. When the drying chamber 200 is pushed into the accommodating chamber 110, the drying chamber 200 pushes the sliding portion 120, so that the air outlet 111 can be opened, and dry air can be supplied into the drying chamber 200.
By adopting the technical scheme of the embodiment, a set of drying system can be used for providing drying gas for a plurality of drying chambers 200, and operators can add and take out the drying chambers 200 at any time according to the needs, so that equipment and medicines can be dried at any time and taken and placed at any time. The drying chambers 200 do not affect each other, and the system can automatically adjust the power according to the number of the drying chambers 200 put into use. The embodiment is convenient to use and flexible in operation. Compared with purchasing a plurality of drying boxes, the embodiment only needs one set of drying system, and has low purchase cost and maintenance cost; the input and the taking out of the drying box only need to adjust the power of the drying system, and frequent start-stop and preheating of equipment are not needed, so that the efficiency is improved, the service life of the equipment is prolonged, and the electric energy is saved; when any drying chamber 200 is taken out, the drying system is not exposed to the outside air, so that the drying system is kept in a dry state at any time and can be put into use at any time.
As a further scheme of this embodiment: the outside of sliding part 120 is fixed with pipe 130, and first through-hole 131 has been seted up to the lateral wall of pipe 130, and the outside cover of pipe 130 is equipped with sleeve pipe 140, and sleeve pipe 140 inside wall and pipe 130 outside wall sealing sliding contact, sleeve pipe 140 lateral wall have seted up the second through-hole 141. A spring 150 is disposed between the sleeve 140 and the sliding portion 120 and over the circular tube 130, and the spring 150 tends to push the sleeve 140 outwards. When the sleeve 140 is positioned at the outermost end, the first through hole 131 and the second through hole 141 are dislocated and not communicated with each other; when the sleeve 140 is positioned at the innermost end, the first through hole 131 and the second through hole 141 are in overlapping communication. The inner side of the sliding part 120 is provided with an air return opening 160 on the accommodating cavity 110, and the inner side of the circular tube 130 is communicated with the inner side of the sliding part 120. The end surface of the drying chamber 200 near the sliding part 120 is provided with an air outlet 210. It is also generally possible to provide an elastic member to urge the sliding portion 120 to rest at the outermost end of the accommodating chamber 110 when not subjected to an external force, and this may be achieved in other manners, for example, by pushing out the sliding portion 120 with a high air pressure, which will be explained in detail in this embodiment.
When the drying chamber 200 is not placed in the accommodating chamber 110, the sliding portion 120 is at rest at the outermost end, the air outlet 111 is blocked, the first through hole 131 and the second through hole 141 are dislocated, and the air return 160 is blocked from communicating with the outside. When the drying chamber 200 is horizontally inserted into the accommodating chamber 110, the drying chamber 200 pushes the sleeve 140 and the sliding part 120 backward, and finally the first through hole 131 and the second through hole 141 are overlapped and communicated, the air outlet 111 is opened, so that the dried air can enter the drying chamber 200 through the air outlet 111, and be discharged out of the drying chamber 200 through the first through hole 131, the second through hole 141 and the air outlet 210, and the drying process is performed on the equipment or medicine in the drying chamber 200. With this technical scheme, the closing and opening of the air passage and the air exhaust passage can be automatically realized by taking and placing the drying chamber 200.
As a further scheme of this embodiment: referring to fig. 3 to 7, the drying chamber 200 is divided into an upper open type drying chamber 200 and a full-enclosed type drying chamber 200. The upper open type drying chamber 200 is a rectangular container with an open upper surface, and the dried air may be directly introduced into the drying chamber 200 from above the drying chamber 200 and discharged through the air outlet 210. Further, the air inlet 220 may be formed at a position opposite to the air outlet 111 on the lower surface of the upper open type drying chamber 200, so that the dried air can enter the drying chamber 200 from the upper and lower directions, and the drying is more uniform. The drying chamber 200 is a rectangular container with six sides closed, and is provided with an openable door, which can be arranged on any surface, not shown in the figure. The air inlet 220 is formed at a position of the fully enclosed drying chamber 200 opposite to the air outlet 111. The switch structure is disposed in the fully enclosed drying chamber 200, when the fully enclosed drying chamber 200 is placed in the accommodating cavity 110, the air inlet 220 and the air outlet 210 are both opened, and when the fully enclosed drying chamber 200 is taken out from the accommodating cavity 110, the air inlet 220 and the air outlet 210 are both closed.
With this solution, different drying chambers 200 can be selected as desired. For example, when drying equipment, the upper open type drying chamber 200 can be selected, so that the equipment can be conveniently taken and placed; when the drying object is a moisture-sensitive medicine, the fully-enclosed drying chamber 200 can be selected, the fully-enclosed drying chamber 200 can be taken out after drying is finished, the fully-enclosed drying chamber 200 can isolate external air, so that the internal medicine can be kept dry for a long time, and the medicine can be taken out again when the medicine is needed to be taken out, so that the space of a drying box is not occupied, and the drying of the medicine is maintained.
Further, a yielding hole 230 is formed on an end surface of the fully enclosed drying chamber 200, which is close to the sliding portion 120, a sliding rail 240 is fixed on the inner side of the end surface, a first baffle 250 is slidably disposed on the sliding rail 240, and the first baffle 250 is parallel to the end surface. The inside of the air inlet 220 of the fully enclosed drying chamber 200 is slidably provided with a second baffle 260 closely attached to the inner side wall. And a transmission rod 270, wherein one end of the transmission rod 270 is connected with the first baffle 250, and the other end is connected with the second baffle 260, so that the first baffle 250 and the second baffle 260 can synchronously slide. An elastic member is also provided, which tends to push the first shutter 250 and the second shutter 260 in the direction of the sliding portion 120. The elastic member is conventional in the art and is not shown in the drawings, and can be flexibly selected by those skilled in the art. When the fully enclosed drying chamber 200 is separated from the accommodating cavity 110, the first baffle 250 is tightly attached to the inner side wall to close the air outlet 210, and the second baffle 260 can shield the closed air inlet 220; when the fully enclosed drying chamber 200 is pushed horizontally into the accommodating chamber 110, the sleeve 140 extends into the fully enclosed drying chamber 200 through the abdication hole 230 and pushes the first baffle 250 and the second baffle 260 to displace, so as to open the air outlet 210 and the air inlet 220.
By adopting the technical scheme, the communication and self-sealing of the fully enclosed drying chamber 200 can be skillfully realized by utilizing the matching relationship between the sliding part 120 and the fully enclosed drying chamber 200. The sleeve 140 goes deep into the fully enclosed drying chamber 200 to directly push the first baffle 250, which not only reduces the space occupied by the switch structure, but also makes the air in the fully enclosed drying chamber 200 directly enter the circular tube 130 from the periphery of the first baffle 250, thereby reducing the flow resistance and optimizing the flow field.
As a further scheme of this embodiment: referring to fig. 1 and 8, an air tank 300 is commonly connected downstream of each air return port 160, a circulation air pump 400 is connected downstream of the air tank 300, and the downstream of the circulation air pump 400 is connected to each air intake port 220. A dehumidifying assembly 500 is provided upstream or downstream of the circulation air pump 400. The circulation air pump 400 provides power for air circulation, and the air circulated in the drying system is dehumidified by the dehumidifying assembly 500.
As a further scheme of this embodiment: the pressure sensor 600 is provided in the air box 300, and the air pressure in the air box 300 maintains a positive pressure. The positive pressure environment can effectively prevent external air from penetrating into the drying system and the drying chamber 200, maintain the drying environment in the drying system and the drying chamber 200, and simultaneously, the positive pressure environment can also push the sliding part 120 to slide outwards without using elastic components, so that the device structure is simplified. Further, a relief valve 310 is installed on the air box 300 for preventing the overpressure of the system.
As a further scheme of this embodiment: the air-supplementing and dehumidifying filter 710 is further included, the downstream of the air-supplementing and dehumidifying filter 710 is sequentially connected with an air-supplementing pump 720 and a one-way valve 730, and the downstream of the one-way valve 730 is communicated with the air tank 300. When the gas pressure in the gas tank 300 is lower than the normal value, the air supplementing pump 720 is started to supplement air, and the dehumidifying and filtering treatment is performed when the outside air is supplemented to the dehumidifying and filtering device 710.
As a further scheme of this embodiment: the device also comprises a temperature control system, wherein the temperature control system comprises an outer heat exchanger 830, a compressor 820, an inner heat exchanger 810 and an expansion valve 840 which are sequentially and circularly connected to form a closed circulation system; the temperature control system further includes a temperature sensor 850, and the inner heat exchanger 810 and the temperature sensor 850 are disposed within the gas box 300. The principle of the temperature control system is basically common knowledge in the art, and is not described in detail herein. By arranging the temperature control system, the whole drying system can be controlled in a stable temperature environment, and constant-temperature drying is realized.
The foregoing description of the preferred embodiments of the present invention should not be taken as limiting the invention, but rather should be understood to cover all modifications, equivalents, and alternatives falling within the spirit and principles of the invention.
