Abstract
Description
Technical Field
[0001] The utility model belongs to the field of purification equipment, in particular to an environment purification device for a white tea processing workshop. Background Art
[0002] White tea is a popular variety of tea. The fresh leaf raw materials in white tea production are mainly selected from multi-hair tea tree varieties (such as Fuding dahao tea and Zhenghe dabai tea). The tea hairs are easy to fall off during the processing. The movement of people and the wind generated by machinery during the processing will cause the tea hairs to float and form tea dust.
[0003] Tea dust is both a kind of production dust and a kind of plant-based mixed dust. Tea dust mainly comes from two aspects: (1) during the processing of fresh tea leaves (such as drying, screening, air separation, picking and stacking), the softness of fresh tea leaves gradually decreases due to water loss, and the tea leaves are crushed and broken by internal and external mechanical forces such as friction, squeezing and cutting, resulting in tiny particles; (2) non-tea substances such as coal ash, mud and sand and microorganisms mixed in the processing environment. The largest amount of tea dust is generated during the fine processing of tea. The raw tea needs to be transported by the horizontal movement of the conveyor belt and the up and down movement of the elevator. During this period, the raw tea is subjected to different degrees of vibration from front to back and up and down to form tea dust; the tea screening machine relies on the mechanical force of rotation and shaking to screen the tea through sieve holes of different sizes. This process will also cause the dispersion of tea dust due to the large movement amplitude and violent collision; the air separator uses a uniform air flow to separate the materials according to the weight, shape and wind-receiving area of the tea. In this process, the wind force will intensify the generation and diffusion of tea dust; the color sorter has a similar function to the stem picker, which is mainly to separate the tea leaves from the stems and other foreign matter. The tea stems are hit by the compressed air during the falling process, and tea dust is quickly formed; hot air drying will blow up the tea dust on the tea leaves and cause pollution; and the pile leveler is also prone to form broken tea dust when working.
[0004] Tea dust particles are tiny and easy to float. A certain concentration of tea dust will affect the appearance, lighting and cleanliness of the production workshop. Tea dust will also cause lung and respiratory diseases in processing personnel. Traditional white tea processing workshop purification equipment generally uses vacuum cleaners or ventilation fans. Such equipment has the following disadvantages: the impeller is directly set in the air duct and contacts with the floating tea hairs. Long-term use will cause the tea hairs to accumulate and be inconvenient to clean; the noise is loud, the dust removal effect is average, and the workshop environment is poor. Utility Model Content

[0025] In order to make the purpose, technical solution and advantages of the embodiment of the utility model clearer, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is a part of the embodiment of the utility model, not all the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0026] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.
[0027] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 As shown, an embodiment of the utility model is an environment purification device for a white tea processing workshop, comprising a blowing component 1, a drying component 2 and a dust collecting component 3.
[0028] The blowing assembly 1 comprises a blowing cover 101 , an air duct 102 and a turbofan part 103 . The blowing cover 101 is placed horizontally, and the air duct 102 is vertically connected to the lower part of the blowing cover 101 . The lower part of the air duct 102 is connected to the turbofan part 103 .
[0029] The blowing hood 101 includes a first cylinder 1011, a second cylinder 1012 and a curved surface 1013. The first cylinder 1011 and the second cylinder 1012 are closed at the right end. The interlayer formed between the first cylinder 1011 and the second cylinder 1012 is connected to the air duct 102. The curved surface 1013 is connected to the left end of the first cylinder 1011 and curled inward. There is a circular gap between the curved surface 1013 and the second cylinder 1012 that becomes narrower from wide.
[0030] Bernoulli's principle is a basic principle in fluid mechanics. It was proposed by Swiss fluid physicist Daniel Bernoulli in 1726. Its essence is the conservation of mechanical energy of an ideal fluid. Under ideal conditions, at any cross section of the same flow tube, the sum of the kinetic energy, potential energy and pressure potential energy of a unit volume of fluid is a constant. Its most famous inference is: when the flow is constant, the greater the flow rate, the smaller the pressure. The air blown into the air duct 102 by the turbofan section 103 enters the interlayer formed between the first cylinder 1011 and the second cylinder 1012, and then the air is blown out from the annular gap between the curved surface 1013 and the second cylinder 1012. The shape of the annular gap changes from wide to narrow, and the air flow rate is accelerated therein, forming a horizontal high-speed airflow. At the same time, the air flow rate in the blowing hood 101 is accelerated, the pressure is reduced, and the air outside the blowing hood 101 flows into the blowing hood 101.
[0031] Preferably, the diameters of the first cylinder 1011 and the second cylinder 1012 narrow from left to right, further strengthening the Bernoulli effect in the blowing hood 101 .
[0032] The turbofan part 103 includes a turbofan housing 1031, a turbofan motor 1032, a turbofan impeller 1033 and an air intake duct 1034. The turbofan motor 1032 is vertically placed in the turbofan housing 1031. The turbofan impeller 1033 is installed on the output shaft of the turbofan motor 1032 and blows air from bottom to top. The side wall of the turbofan housing 1031 is connected to the air intake duct 1034. The air intake duct 1034 can be connected to the external ventilation of the workshop, and can continuously replenish the fresh air from the outside into the workshop, thereby avoiding repeated circulation of stale air in the workshop and making it difficult to reduce the concentration of suspended matter in the air.
[0033] The right end of the blowing hood 101 is connected to the drying component 2 .
[0034] The drying component 2 has an inclined cylinder 201 , and an electric heating pipeline 202 is spirally arranged inside the wall of the inclined cylinder 201 .
[0035] Preferably, the inclined cylinder 201 is inclined from left to right, and its inclination angle is greater than forty-five degrees.
[0036] Tea dust is a kind of dust with poor fluidity, small particle size, strong aggregation, and easy to absorb water, resulting in a high moisture content. Tea dust has a large repose angle and a small sliding angle, so the inclination angle of the inclined cylinder 201 should exceed 45°, and an electric heating pipeline 202 is set for drying to ensure that the tea dust slides.
[0037] Preferably, an inspection channel 203 is provided above the inclined cylinder 201, and the inspection channel 203 is provided with an inspection sealing plate 2031. Preferably, a non-return mechanism 204 is provided at the right end of the inclined cylinder 201, and the non-return mechanism 204 includes a spring hinge 2041 and a non-return sealing plate 2042. A set of non-return sealing plates 2042 is installed at the right end of the inclined cylinder 201 through the spring hinge 2041. When the turbofan part 103 is working, the non-return sealing plate 2042 opens and closes to the right. When the turbofan part 103 stops, the non-return sealing plate 2042 automatically closes to prevent tea dust from flowing back.
[0038] The right end of the drying component 2 is connected to the dust collecting component 3.
[0039] The dust collecting component 3 has a dust collecting box 301, a filter screen 302 is arranged on the right wall of the dust collecting box 301, a box door 303 is arranged on the front of the dust collecting box 301, the filter screen 302 is used to intercept the tea dust in the dust collecting box 301, and the box door 303 can be opened to centrally clean the collected tea dust.
[0040] The device embodiments described above are merely illustrative, wherein the units described as separate components may or may not be physically separated, and the components displayed as units may or may not be physical units, that is, they may be located in one place, or they may be distributed on multiple network units. Some or all of the modules may be selected according to actual needs to achieve the purpose of the scheme of this embodiment. Ordinary technicians in this field can understand and implement it without paying creative labor.
[0041] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein.
