Description

Technical Field

[0001] The present invention relates to the technical field of dehumidification, and in particular to a device capable of dehumidifying a pharmaceutical and chemical production workshop. Background Art

[0002] In a pharmaceutical and chemical production workshop, humidity control is crucial. The production processes of many pharmaceuticals and chemical products have strict requirements for the environmental humidity. For example, in the production of solid dosage forms of pharmaceuticals (such as tablets, capsules), high humidity may cause the raw materials or finished products to be affected by moisture, which will affect the quality and stability of the pharmaceuticals. The affected pharmaceuticals may have problems such as caking, deterioration, and decomposition of active ingredients. In chemical production, for some water-sensitive chemical reactions, such as the synthesis of organometallic compounds, excessive humidity will introduce moisture, interfere with the reaction process, and reduce the yield and purity of the products. Therefore, dehumidification equipment is usually used in existing pharmaceutical and chemical production workshops.

[0003] Currently, independent dehumidification equipment is usually adopted in pharmaceutical and chemical production workshops and distributed in the workshop for dehumidification. These dehumidification equipment generally adopt condensation dehumidification, adsorption dehumidification or absorption dehumidification, and there is no equipment that can combine condensation dehumidification and adsorption dehumidification to improve the dehumidification effect. And in the existing condensation dehumidification equipment, a compressor, an evaporator and a condenser are usually arranged. Utilizing the characteristic that water vapor condenses into liquid water when air is cooled, by allowing the relatively high-temperature humid air to contact the relatively low-temperature evaporator, the air temperature is reduced below the dew point temperature, and then the water vapor condenses and is separated. Then the heat-absorbing refrigerant in the evaporator flows to the condenser for cooling and then is recycled. However, in specific use, more water droplets are likely to condense on the surface of the evaporator, reducing the effective area of direct contact with the air and thus reducing the dehumidification effect.

[0004] Chinese Patent with application number CN201821360753.3 discloses "a dehumidification device for pharmaceutical and chemical production; including a kettle body, a compressor, multiple groups of condensers, a compression condensation pipe, two groups of radiators and a variable-frequency fan. A heating placement cavity is arranged on the left side inside the kettle body, a condensation placement cavity is arranged on the right side inside the kettle body, a partition is arranged in the middle of the kettle body, a gas through hole is communicated and arranged at the bottom of the partition, a fan hole is communicated and arranged at the top of the left side wall of the kettle body, the compression condensation pipe is connected with multiple groups of condensers, a gas outlet is communicated and arranged at the top of the right side wall of the kettle body to communicate with the condensation placement cavity, an output pipe and a heat dissipation pipe are arranged on the compressor, and multiple groups of water vapor outlets are communicated and arranged at the top of the heating placement cavity; also including a drain pipe, a top block, a positioning rod, a positioning pipe, a sleeve spring and a drain head. The bottom side wall of the condensation placement cavity is of an inclined surface structure, the inner bottom of the drain pipe is conical, the outer side wall of the top block is conical, a drain placement cavity is arranged inside the drain head, and a drain access port is communicated and arranged at the top of the drain head".

[0005] Although this technical solution can adjust the gas flow velocity inside the kettle body by adjusting the variable-frequency fan, thereby adjusting the working efficiency of the dehumidification equipment for pharmaceutical and chemical production, facilitating the control of the drying degree and drainage, it cannot effectively remove the condensed water droplets on the surface of the evaporator, resulting in low dehumidification efficiency of the evaporator, and it can only use the single method of condensation dehumidification.

Detailed implementation manners

[0036] The following will combine the attached Figure 1 to the attached Figure 11 The technical solutions in the embodiments of the present invention will be described clearly and completely. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present invention.

[0037] It should be noted that if there are directions involved in the embodiments of the present invention, they shall be subject to those shown in the drawings. For example, the front and the rear are based on Figure 1 as the standard. Specifically, the Figure 1 left side of Figure 1 is the front, and the Figure 2As shown, the left-right direction is generally the horizontal direction, and the up-down direction shown in the figure is the vertical direction. If a specific posture changes, the directional indication will also change accordingly. Example

[0038] A dehumidification device includes a device housing 1, an air inlet fan 6 is installed at the front end of the device housing 1, and the rear side of the air inlet fan 6 is connected to an air inlet pipe 7, an evaporation box 8, and an air outlet pipe 9 in sequence. An evaporator 12 is installed in the evaporation box 8, a slide bar 17 is slidably provided in the evaporation box 8, and a scraping sponge 18 that fits the surface of the evaporator 12 is installed on the slide bar 17. A stop plate 19 is installed on the inner wall of the evaporation box 8, and a push rod 20 is connected to the slide bar 17. The push rod 20 slides through the evaporation box 8 in a sealed manner and extends to the outside thereof. A telescopic member 29 is installed in the device housing 1, and is connected to a drive plate 30 through the telescopic member 29. Figure 6 As shown, the telescopic member 29 can adopt an existing electric cylinder, an electric hydraulic cylinder or an electric telescopic rod, and the evaporator 12 installed in the evaporation box 8 is also combined with an existing compressor and condenser. Since it is a mature existing technology, only the evaporator 12 is described;

[0039] A driving component 1 is provided on the push rod 20. The driving component 1 is used to drive the scraping sponge 18 to cooperate with the abutment plate 19 to squeeze when the driving plate 30 moves. An air outlet 10 is installed at the upper end of the equipment housing 1, and a drying filter element 11 is provided in the air outlet 10. The two sides of the equipment housing 1 are slidably connected with a clamping column 38 that is locked with the drying filter element 11. A driving component 2 is provided on the clamping column 38. The driving component 2 is used to drive the clamping column 38 to cancel the locking position with the drying filter element 11 when the driving plate 30 moves, so that the present device can combine the condensation dehumidification of the evaporator 12 and the adsorption dehumidification of the drying filter element 11 to improve the dehumidification effect and efficiency.

[0040] Furthermore, a guide rod 14 is connected between the inner walls of both sides of the evaporation box 8, and a slider 15 is provided on the outer sliding sleeve of the guide rod 14. The slide bar 17 is connected to the slider 15, and the push rod 20 is connected to the slider 15. The outer sleeve of the guide rod 14 is provided with a spring 16, and the two ends of the spring 16 are respectively connected to the slider 15 and the inner wall of the evaporation box 8, as shown in FIG. Figure 7 As shown, the sliding sleeve of the slider 15 on the guide rod 14 and the connection of the slide bar 17 on the slider 15 enable the slider 15 and the slide bar 17 to slide stably, and as shown in FIG. Figure 8As shown, the guide rods 14 are grouped in pairs of two, and are provided at the upper and lower ends of the inner walls on the left and right sides of the evaporation box 8. A slider 15 is sleeved outside each group of guide rods 14. Therefore, there are also four groups of combinations of the slider 15 and the slide bar 17. A push rod 20 is also connected to each slider 15. In this way, under the action of an external force, the push rod 20 can be pushed to drive the slider 15 to slide, so that the slide bar 17 and the scraping sponge 18 can be pushed to fit along one side of the evaporator 12 to the other side, thereby realizing the scraping of the water droplets on the outside of the evaporator 12. When the scraping sponge 18 is separated from the surface of the evaporator 12 and gradually contacts the abutment plate 19, the water adsorbed and scraped by itself can be squeezed out. The setting of the first spring 16 can facilitate the reset of the slider 15, the slide bar 17 and the scraping sponge 18 to be pushed to one side without the action of an external force, so as to facilitate the next scraping, avoid excessive condensation water droplets adhering to the evaporator 12, reduce the effective contact with the humid air, and improve the effect of condensation dehumidification.

[0041] Further, a plurality of circumferential fins 13 are sleeved on the outside of the evaporator 12 at equal intervals. The scraping sponge 18 is correspondingly sleeved on the surfaces of the respective circumferential fins 13 and the surface of the evaporator 12. The circumferential fins 13 are arranged along the air flow direction in the evaporation box 8. Air inlet grids 51 are provided on both sides of the evaporation box 8, and are respectively connected to the air inlet pipes 7 and the air outlet pipe 9 on both sides through the air inlet grids 51. As Figure 7 shown, the circumferential fins 13 are arranged along the front and back air flow directions of the evaporation box 8, which is beneficial to the smooth flow of the humid air between the adjacent circumferential fins 13, improves the flow efficiency of the humid air. At the same time, the circumferential fins 13 can also increase the contact surface with the humid air, improve the efficiency and effect of condensation dehumidification, and the scraping sponge 18 also fits with the respective circumferential fins 13, and can also scrape the condensation water droplets on the surface of the circumferential fins 13, improving the efficiency of condensation dehumidification.

[0042] Further, the interior of the equipment housing 1 is divided into an air inlet chamber 2, an air outlet chamber 3 and a control chamber 4. The air inlet pipe 7, the evaporation box 8 and the air outlet pipe 9 are all arranged in the air inlet chamber 2. An air inlet 5 is provided on the front end face of the equipment housing 1 and is communicated with the air inlet chamber 2. The front side of the air inlet fan 6 is communicated with the air inlet 5. The air outlet pipe 9 is communicated with the air outlet chamber 3. The air outlet 10 is installed in the air outlet chamber 3. The push rod 20 also extends slidably in the control chamber 4. The telescopic member 29 and the driving plate 30 are both arranged in the control chamber 4. As Figure 2 and 4 shown, such a three-chamber setting helps to divide the functions of each chamber and realize modular management and operation and maintenance. Moreover, the single chamber of the air outlet chamber 3 is communicated with the air outlet pipe 9, and the air outlet 10 is installed in the air outlet chamber 3, which can not affect other chambers when the air is discharged and is not affected by other chambers.

[0043] Further, the first driving component includes a first guiding slide rod 31, a sleeve 32, a slide plate 33, a frame 35, and a first rotating plate 36. The first guiding slide rod 31 is connected to the inner wall of the control chamber 4. The sleeve 32 is slidably sleeved outside the first guiding slide rod 31. The slide plate 33 is connected to the sleeve 32. The frame 35 is connected to the push rod 20. A first rotating plate 36 is rotatably connected between the frame 35 and the slide plate 33. The lower end of the driving plate 30 cooperates and abuts against the slide plate 33. As Figure 6 shown, when the telescopic member 29 drives the driving plate 30 to move downward, it can abut against the slide plate 33 to drive the sleeve 32 to move downward, and push the first rotating plate 36 to rotate, so as to push the push rod 20 to drive the scraping sponge 18 to move towards the abutting plate 19 on the front side of the evaporator 12, thereby realizing the scraping of the condensed water droplets on the outer side of the evaporator 12, and squeezing and discharging the water adsorbed in the scraping sponge 18.

[0044] Further, a second spring 34 is sleeved outside the first guiding slide rod 31, and the two ends of the second spring 34 are respectively connected to the first guiding slide rod 31 and the sleeve 32. As Figure 7 shown, the setting of the second spring 34 can further improve the reset effect of the slider 15, the slide bar 17, and the scraping sponge 18 when the driving plate 30 moves upward.

[0045] Further, a collection box 21 is also connected to the lower end of the evaporation box 8. A liquid discharge port 22 is installed on the collection box 21. An opening 23 is formed through between the collection box 21 and the evaporation box 8. A second guiding slide rod 24 is connected to the inner wall of the collection box 21. A cover plate 25 that cooperates with the opening 23 to block is slidably sleeved outside the second guiding slide rod 24. A third spring 26 is sleeved outside the second guiding slide rod 24. The two ends of the third spring 26 are respectively connected to the cover plate 25 and the inner wall of the collection box 21. The upper end of the cover plate 25 is connected to a connecting rod 27. The upper end of the connecting rod 27 penetrates through the evaporation box 8 and extends into the evaporation box 8, and an arc-shaped block 28 is connected to the extending end. The lower slide bar 17 is also connected to an arc-shaped block 28. The adjacent arc-shaped blocks 28 are in sliding contact with each other. As Figure 8 、 9 and 10 shown, when the scraping sponge 18 is pushed to move or moves reversely and resets under the action of the first spring 16 and the second spring 34, it can drive the arc-shaped block 28 connected to the lower slider 15 to slide and abut against the arc-shaped block 28 connected to the connecting rod 27, and push the connecting rod 27 to drive the cover plate 25 to slide downward outside the second guiding slide rod 24 and compress the third spring 26. At this time, the opening 23 is opened, and the water squeezed out from the scraping sponge 18 in the evaporation box 8 can be guided into the collection box 21 through the opening 23 and finally discharged through the liquid discharge port 22. When the two arc-shaped blocks 28 move away from each other, under the elastic force of the third spring 26, the cover plate 25 moves upward to block the opening 23 again, avoiding the excessive accumulation of water in the evaporation box 8, affecting the dehumidification effect of the evaporator 12 therein, and effectively improving the dehumidification effect and efficiency of condensation.

[0046] Further, guide slide bars three 39 are connected to both sides of the inner wall of the air outlet bin 3. A slide seat 40 is slidably sleeved on the outer side of the guide slide bars three 39. A clamping post 38 is connected to the slide seat 40. A spring four 41 is sleeved on the outer side of the guide slide bars three 39, and both ends of the spring four 41 are respectively connected to the guide slide bars three 39 and the inner wall of the air outlet bin 3. As Figure 6 and 11 shown, the sliding of the slide seat 40 on the outer side of the guide slide bars three 39 can stabilize the sliding of the clamping post 38, and the setting of the spring four 41 can make the slide seats 40 on both sides and the clamping posts 38 thereon approach each other.

[0047] Further, the driving component two includes a clamping position hole 37, a cross plate 44, and a top plate 45. The clamping position holes 37 are opened on both sides of the drying filter element 11 and penetrate through the air outlet 10. The clamping posts 38 are inserted in cooperation with the clamping position holes 37. The cross plate 44 is located below the air outlet 10, and a second rotating plate 43 is rotatably connected between the cross plate 44 and the slide seats 40 on both sides. The lower end of the cross plate 44 hermetically slides through the air outlet bin 3 and extends into the control bin 4, and a top plate 45 that cooperates with and abuts against the driving plate 30 is connected to the extending end. As Figure 6 shown, when the telescopic member 29 drives the driving plate 30 to move upward, it can push the top plate 45 and the cross plate 44 to move upward, drive the second rotating plate 43 to rotate, and push the slide seats 40 on both sides to drive the clamping posts 38 to move away from each other, canceling the clamping of the clamping posts 38 and the clamping position holes 37, which facilitates removing the drying filter element 11 from the air outlet 10 for replacement. And since it is in the state of replacing the drying filter element 11 at this time, it can not only ensure the effectiveness of adsorption dehumidification, but also facilitate the operation and maintenance of the adsorption dehumidification related components. At the same time, when performing operation and maintenance, the device is shut down, and thus the scraping sponge 18 is in the reset state without external force.

[0048] Further, as Figure 1 and 6 shown, a filter grille 46 is installed in the air inlet 5 by internal thread, and handles 47 are connected to both sides of the filter grille 46, which is convenient for pulling the handles 47 to screw out the filter grille 46 for cleaning, avoiding a large amount of dust accumulating on it after long-term use and reducing the air intake efficiency. The equipment housing 1 is provided with side air inlet pipes 49 at the front ends on both sides of the air inlet 5, and the side air inlet pipes 49 communicate with the air inlet 5. A pipe cap 48 is installed at the front end of the side air inlet pipe 49 by thread, which is convenient for opening the pipe cap 48. A hose is clamped on the side air inlet pipe 49 and pulled to the outside within a certain range to realize multi-point air intake at the air inlet 5 and the outer hose nozzle, so as to increase the use radiation range. An air outlet grille 50 is installed at the upper end of the air outlet 10 by bolt, which can prevent the falling of dust and other impurities and play a role in protecting the drying filter element 11. When replacing the drying filter element 11, only the air outlet grille 50 needs to be removed together. A control panel 42 is installed at the front end of the equipment housing 1, which is convenient for controlling the equipment.
