Description

TECHNICAL FIELD

[0001] The utility model mainly relates to the technical field of pipeline drying and bacteria prevention, and particularly relates to a clean pipeline drying and bacteria prevention device. BACKGROUND

[0002] In many industrial fields, such as food and beverage production, pharmaceutical manufacturing, and electronic chip manufacturing, the use of clean pipelines is crucial. These pipelines are used to transport various raw materials, products, or media, and their cleanliness directly affects product quality and production safety. For example, in the pharmaceutical industry, residual moisture and bacteria growing in the pipeline can contaminate the medicine, seriously affecting the quality of the medicine and even endangering the health of patients; in electronic chip manufacturing, impurities introduced by unclean pipelines can interfere with chip performance and reduce the yield rate. Therefore, effective drying and bacteria prevention of clean pipelines are key links to ensure normal production.

[0003] Traditional pipeline drying methods mainly include natural air drying, hot air drying, and vacuum drying. Natural air drying is extremely inefficient and is easily affected by external environments, such as dust and microorganisms, which can re-contaminate the pipeline, making it difficult to meet the requirements of modern large-scale production in terms of efficiency and cleanliness. Although hot air drying is relatively fast, it has the problem of uneven heating. Common hot air drying equipment often only delivers hot air from a single direction, causing uneven heating of different parts of the pipeline, with some areas being over-dried and others being under-dried, affecting the service life of the pipeline and also failing to ensure complete bacterial killing. Vacuum drying equipment is complex in structure, high in cost, and difficult to maintain, which limits its widespread application for small and medium-sized enterprises due to the high investment. In terms of pipeline placement and fixation, previous device designs are not reasonable. The pipeline may shake or shift during the drying process, causing the hot air to not act uniformly on the surface of the pipeline, affecting the drying effect. Meanwhile, unstable placement may also cause the pipeline to collide and be damaged, increasing maintenance costs. SUMMARY

[0034] Pipeline placing mechanism 5 includes rack 51, rack 51 is provided with lifting mechanism 52, lifting mechanism 52 is provided with support frame one 53 and support frame two 54 which are the same structure on the output end, support frame two 54 is arranged above support frame one 53, a plurality of placing grids are arranged at equal intervals on support frame one 53 and support frame two 54, support net 7 is arranged in the placing grid of support frame one 53, and clamping mechanism 6 is arranged in the placing grid of support frame two 54.

[0036] Clamping mechanism 6 includes two air cylinders 61 symmetrically arranged in the placing grid, clamping block 62 is fixedly installed on the output end of air cylinder 61, and clamping groove 63 is formed in clamping block 62.

[0037] Working principle:

[0038] After the device is started, the outside air will naturally flow to the filter 3. The size of the filter 3: 240x240x150mm, outer frame SUS304, outdoor air sampling, the filter 3 uses high-efficiency filter material, such as multi-layer filter screen structure, including primary filter screen for intercepting larger particles of dust, hair and other impurities, and the medium-efficiency filter screen further filters fine dust particles and part of microorganisms to ensure the cleanliness of the circulating air in the oven. When the air flow passes through the filter 3, these impurities are intercepted and adsorbed by the filter screen, thereby ensuring that the output air has high cleanliness. The filtered clean air is continuously extracted into the air inlet end of the fan 2 under the negative pressure action of the fan 2. The fan 2 is a centrifugal fan with high wind pressure and large flow characteristics, and the impeller inside rotates at high speed, so that the air obtains high kinetic energy under the action of centrifugal force, so that it can be smoothly blown to the pipeline heater 4. In addition, the air outlet of the drying box 1 is equipped with a dehumidifying medium-efficiency filter, and the filter is high-temperature resistant to ensure that the return air cleanliness meets the requirements.

[0039] The air entering the fan 2 is discharged from its air outlet and directly enters the air outlet pipe 41 of the pipeline heater 4. The air outlet pipe 41 is arranged with a heating wire 42 wound in a spiral shape. The heating wire 42 generally uses a material with high resistance such as nickel-chromium alloy. When the current passes through the heating wire 42, the electrical energy is converted into heat energy, and the heating wire 42 rapidly heats up. In the process of air flowing in the air outlet pipe 41, the air absorbs heat through heat conduction, and the temperature gradually rises. The heating system is equipped with an intelligent temperature control device, which can automatically adjust the current size of the heating wire 42 according to the pre-set temperature value, so as to accurately control the heating temperature of the air, and ensure that the air can be heated to the best temperature for drying the pipeline. Generally, this temperature range will be set between 60-80 degrees Celsius, which can ensure efficient drying and will not cause damage to the pipeline material.

[0040] The heated high-temperature air flows into the air deflector 43 from the air outlet pipe 41. The air deflector 43 has a special structure design, and the internal space is in a diffusion shape, which can make the hot air uniformly distributed and directed to different air outlets. Part of the hot air is directly blown to the top of the drying chamber 11 through the air outlet two 46. The shape and angle of the air outlet two 46 are carefully designed, so that the hot air is blown out at a certain inclined angle, which can uniformly cover the pipes in the top area of the drying chamber 11 and heat and dry the pipes in all directions. Another part of the hot air enters the air deflector frame 12 through the air outlet one 44. The air deflector frame 12 is installed on the side wall of the drying box 1, and the outside is wrapped with the heat preservation plate 13. The heat preservation plate 13 is usually made of polyurethane foam, rock wool and other low thermal conductivity heat preservation materials, which can effectively prevent heat loss to the outside. The hot air flows in the air deflector frame 12, and since the air deflector frame 12 is provided with a plurality of evenly distributed air outlet holes 14 at the bottom, the hot air is blown out from the air outlet holes 14 to form an upward airflow, which heats and dries the pipes at the bottom and middle of the drying chamber 11. This way of heating the pipes from the top and bottom at the same time can quickly and uniformly heat the pipes at all parts, greatly improving the drying efficiency. In order to effectively monitor the temperature in the drying chamber 11, a temperature control instrument and temperature monitoring probes are provided, and the temperature monitoring probes are distributed in the middle position of the box.

[0041] The control system of the drying box 1 adopts touch screen, PLC, printer and temperature control meter control. The system can be well automatically controlled, the temperature in the oven is kept constant at the set value, and the alarm bell will sound when the limit is exceeded. The control cabinet is arranged on the side of the box body

[0042] In other embodiments, in order to ensure the uniformity of the air distribution in the drying chamber 11, low-noise high-temperature axial flow fans 1.5KWx2 are provided at the top of the device. The air volume is adjusted by the air adjusting plate to make the indoor temperature distribution more uniform and the cleaning and disassembly more convenient.

[0043] When placing the pipes, the pipes to be dried are placed in the placing grid from top to bottom, and the bottom of the pipe is placed on the support net 7 of the support frame one 53. The support net 7 is woven from stainless steel wire and has certain strength and air permeability, which can provide stable bottom support for the pipe and does not hinder the heating of the pipe from below. The clamping mechanism 6 starts to work, and after receiving the control signal, the two air cylinders 61 symmetrically arranged in each placing grid extend the piston, and push the clamping block 62 fixed on the output end of the piston to move towards the pipe. The clamping groove 63 matched with the outer diameter of the pipe is opened on the clamping block 62, and when the clamping block 62 moves to contact the pipe, the clamping groove 63 tightly clamps the pipe, so as to firmly fix the pipe in the placing grid of the support frame two 54, preventing the pipe from shaking or shifting during drying.

[0044] Support frame one 53 and support frame two 54 are installed on the lifting frame 524 of the lifting mechanism 52, after the lifting mechanism 52 is started, the driving motor drives the driving shaft 521 to rotate. The driving shaft 521 and the driven shaft 522 are connected through the chain assembly 523, when the driving shaft 521 rotates, the chain assembly 523 moves with it, driving the lifting frame 524 to move upward along the pre-set guide rail on the rack 51. With the lifting of the lifting frame 524 or the lowering, the support frame one 53, the support frame two 54 and the pipeline placed thereon also rise or fall together.

[0045] In the process of continuously blowing hot air from the top and bottom to the pipeline, the moisture on the surface of the pipeline first absorbs heat and starts to evaporate. Due to the continuous flow of hot air, a certain humidity gradient is formed around the pipeline, so that the moisture inside the pipeline also gradually diffuses to the surface and evaporates. During the drying process, the lifting mechanism 52 can be adjusted according to the actual drying situation. For example, when it is found that the drying speed of the top of the pipeline is faster, and the bottom drying is relatively slow, the height of the pipeline can be appropriately lowered through the lifting mechanism 52, so that the bottom of the pipeline can be more fully contacted with the hot air blown from the bottom, and the drying speed of the bottom is improved, ensuring that the pipeline can uniformly complete the drying process. At the same time, the drying chamber 11 of the drying box 1 adopts a sealed design, reducing the loss of heat and moisture, further ensuring the efficient progress of the drying process. After a period of drying, when the humidity of the pipeline reaches the preset drying standard, the whole drying process is completed.

[0046] The above-described embodiments only express certain embodiments of the present application, which are described in detail and specifically, but should not be understood as limiting the scope of the present application; it should be pointed out that for ordinary skilled in the art, without departing from the concept of the present application, a number of modifications and improvements can be made, which all belong to the protection scope of the present application; therefore, the protection scope of the present application should be subject to the appended claims.
