Description

Technical Field

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

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

[0003] At present, pharmaceutical and chemical production workshops usually use independent dehumidification equipment and distribute it in the workshop for dehumidification. These dehumidification equipment generally use condensation dehumidification, adsorption dehumidification or absorption dehumidification. There is no equipment that can combine condensation dehumidification with adsorption dehumidification to improve the dehumidification effect and effect. In addition, the existing condensation dehumidification equipment usually has a compressor, an evaporator and a condenser. It uses the property that water vapor condenses into liquid water when the air is cold. By allowing the higher temperature humid air to contact the lower temperature evaporator, the air temperature is reduced to below the dew point temperature, and then the water vapor is condensed and separated. Then the heat absorption in the evaporator is cut off and transferred to the condenser for cooling, and then it is recycled. However, in actual use, more water droplets are easily condensed on the surface of the evaporator, which reduces the effective area of ​​direct contact between the air and it, thereby reducing the dehumidification effect.

[0004] The Chinese patent with application number CN201821360753.3 discloses "a kind of dehumidification equipment for pharmaceutical and chemical production; including a kettle body, a compressor, multiple groups of condensers, compression condensing tubes, two groups of heat sinks and a variable frequency fan, a heating placement cavity is arranged on the left side of the kettle body, a condensing placement cavity is arranged on the right side of the kettle body, a partition is arranged in the middle of the kettle body, a gas through hole is arranged at the bottom of the partition, a fan hole is arranged at the top of the left side wall of the kettle body, the compression condensing tubes are connected to the multiple groups of condensers, the top of the right side wall of the kettle body is connected to the condensing placement cavity and a gas outlet is arranged, an output pipe and a heat dissipation pipe are arranged on the compressor, and the top of the heating placement cavity is connected to multiple groups of water vapor outlets; it also includes 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 condensing placement cavity is an inclined structure, the inner bottom of the drain pipe is conical, the outer side wall of the top block is conical, a drainage placement cavity is arranged inside the drainage head, and the top of the drainage head is connected to a drainage access port".

[0005] Although this technical solution can adjust the gas flow speed inside the kettle by adjusting the variable frequency fan, thereby adjusting the working efficiency of the pharmaceutical and chemical production dehumidification equipment, and conveniently controlling the degree of dryness and draining water, it cannot effectively remove the condensed water droplets on the surface of the evaporator, resulting in low evaporator dehumidification efficiency, and can only be performed in a single condensation dehumidification mode.

If a certain posture changes, the directional indication will also change accordingly. Example

Since it is a mature existing technology, only the evaporator 12 is used for description; 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 press against each other when the driving plate 30 moves. An air outlet 10 is installed on 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 engaged 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 engagement with the drying filter element 11 when the driving plate 30 moves, so that the device can combine the condensation dehumidification of the evaporator 12 with the adsorption dehumidification of the drying filter element 11 to improve the dehumidification effect and efficiency.

[0023] Further, a guide rod 14 is connected between the inner walls of both sides of the evaporation box 8, a slider 15 is provided on the outer sliding sleeve of the guide rod 14, a slide bar 17 is connected to the slider 15, a push rod 20 is connected to the slider 15, a spring 16 is provided on the outer sleeve of the guide rod 14, and both 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.

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 spring 16 can facilitate the reset of the slider 15, the slide bar 17 and the scraping sponge 18 to one side when there is no external force, so as to facilitate the next scraping, avoid the adhesion of excessive condensed water drops on the evaporator 12, reduce the effective contact with humid air, and improve the effect of condensation and dehumidification.

[0024] Furthermore, a plurality of wraparound fins 13 are evenly spaced outside the evaporator 12, and a scraping sponge 18 is correspondingly arranged on the surface of each wraparound fin 13 and the surface of the evaporator 12. The wraparound fins 13 are arranged along the air flow direction in the evaporation box 8. Air inlet grilles 51 are provided on both sides of the evaporation box 8, and are respectively connected to the air inlet pipe 7 and the air outlet pipe 9 on both sides through the air inlet grilles 51. Figure 7 As shown, the surrounding fins 13 are arranged along the air flow direction of the front and rear of the evaporation box 8, which is conducive to the smooth circulation of humid air between adjacent surrounding fins 13 and improves the circulation efficiency of humid air. At the same time, the surrounding fins 13 can also increase the contact surface with the humid air, thereby improving the efficiency and effect of condensation and dehumidification. The scraping sponge 18 is also fitted with each surrounding fin 13, and can also scrape off the condensed water droplets on the surface of the surrounding fin 13, thereby improving the efficiency of condensation and dehumidification.

[0025] Furthermore, the device housing 1 is divided into an air inlet bin 2, an air outlet bin 3 and a control bin 4.

Figure 2 and 4 As shown, such a three-compartment setting is helpful to differentiate the functions of each compartment and realize modular management and operation and maintenance. The air outlet compartment 3 is connected with the air outlet pipe 9, and the air outlet 10 is installed in the air outlet compartment 3. When the air is discharged, it will not affect other compartments and will not be affected by other compartments.

[0026] Further, the driving assembly 1 includes a guide slide rod 1 31, a sleeve 32, a slide plate 33, a frame 35, and a rotating plate 1 36. The guide slide rod 1 31 is connected to the inner wall of the control chamber 4, the sleeve 32 is slidably sleeved on the outer side of the guide slide rod 1 31, the slide plate 33 is connected to the sleeve 32, the frame 35 is connected to the push rod 20, and a rotating plate 1 36 is rotatably connected between the frame 35 and the slide plate 33. The lower end of the driving plate 30 cooperates with the slide plate 33, as shown in FIG. Figure 6 As shown, the telescopic member 29 drives the driving plate 30 to move downward, which can abut against the sliding plate 33 to drive the sleeve 32 to move downward, and push the rotating plate 36 to rotate, so as to push the push rod 20 to drive the scraping sponge 18 to move toward the abutting plate 19 on the front side of the evaporator 12, thereby scraping off the condensed water droplets on the outside of the evaporator 12 and squeezing out the water adsorbed in the scraping sponge 18.

[0027] Furthermore, the second spring 34 is sleeved on the outer side of the guide slide bar 1 31, and the two ends of the second spring 34 are connected to the guide slide bar 1 31 and the sleeve 32 respectively, as shown in FIG.

At this time, the opening 23 is opened, and the water squeezed out of the scraper sponge 18 in the evaporation box 8 can be guided into the collection box 21 through the opening 23 and finally discharged through the drain port 22. When the two arc blocks 28 are away from each other, under the elastic force of the spring 3 26, the cover plate 25 moves up to re-block the opening 23, thereby avoiding excessive accumulation of water in the evaporation box 8 and affecting the dehumidification effect of the evaporator 12 therein, thereby effectively improving the effect and efficiency of condensation dehumidification.

Moreover, since the drying filter element 11 is being replaced at this time, it can not only ensure the effectiveness of adsorption and dehumidification, but also facilitate the operation and maintenance of the adsorption and dehumidification related components.
