Abstract
Description
Technical Field
[0001] The invention relates to the technical field of traditional Chinese medicine production equipment, and in particular to a dust removal device for cutting traditional Chinese medicines. Background Art
[0002] Before the preparation of Chinese herbal medicines, pretreatment is required, especially cutting and crushing of Chinese herbal medicines. A large amount of dust will be generated during the cutting and crushing process. If the dust is deposited in the cut Chinese herbal medicines, it will cause contamination of the finished Chinese herbal medicines and affect the product quality. Although the prior art uses a vacuum pump to remove dust through a dust hood, the prior art only directly discharges the dust, causing pollution.
[0003] Chinese herbal medicines need to go through a series of pre-processing steps before preparation, among which cutting and crushing are common processing methods. The purpose of these steps is to make the medicinal ingredients of the herbal medicines easier to extract, and also to facilitate the storage and transportation of the herbal medicines. However, during the cutting and crushing process, a large amount of dust will be generated, which not only poses a threat to the health of the operators, but may also return to the herbal medicines to pollute the herbal medicines, thereby affecting the quality of the final product.
[0004] In the existing technology, an air pump is usually used to remove dust through a dust hood to reduce the pollution of dust to the environment and medicinal materials. However, this method has certain limitations: the existing air pump system usually discharges dust directly into the external environment, which not only causes environmental pollution, but also may affect the health of surrounding residents.
[0005] The design of the vacuum pump and the dust hood may not be able to completely collect all the dust, resulting in some dust still remaining in the medicinal materials or in the environment. Summary of the invention
[0006] The purpose of the present invention is to avoid the deficiencies in the prior art and provide a dust removal device for cutting Chinese medicinal materials. The dust removal device for cutting Chinese medicinal materials can efficiently collect the discharged Chinese medicinal material dust, avoid the discharge of Chinese medicinal material dust into the environment, and has the advantage of low cost.
[0007] To achieve the above object, the present invention provides the following technical solutions:
[0008] Provided is a dust removal device for cutting Chinese medicinal materials, comprising:
[0009] a first channel, the first channel is connected to the Chinese medicinal material cutting chamber, and an exhaust fan is provided at the connection between the first channel and the Chinese medicinal material cutting chamber,
[0010] A buffer channel is placed horizontally, one end of the buffer channel is an inlet, and the other end is an outlet, the inlet is connected to the first channel, the outlet faces outward, and a bulging unit bulging outward is provided in the middle section of the buffer channel,
[0011] The second channel extends in a vertical direction, a middle portion of the second channel is connected to an outlet of the buffer channel, one end of the second channel is connected to a dust collecting box, and the other end is a discharge port.
[0012] In some embodiments, the calibers of the first channels are uniformly arranged, and the caliber of the first channels is not larger than the inlet of the buffer channel.
[0013] In some embodiments, the bulging unit includes a first truncated cone cover and a second truncated cone cover, wherein the expanded bottom surface of the first truncated cone cover is integrally connected with the expanded bottom surface of the second truncated cone cover.
[0014] The side surface of the frustum cover is composed of a soft surface and a hard surface.
[0015] In some embodiments, the middle portion of the buffer channel is connected in series by a plurality of bulging units.
[0016] In some embodiments, a solenoid valve is provided at the inlet of the buffer channel.
[0017] In some embodiments, a pressure sensor is disposed in the swelling unit, and the pressure sensor detects the pressure in the buffer channel.
[0018] In some embodiments, a sleeve is disposed in the second channel, a through hole is opened on a tube surface of the sleeve, and the buffer channel is connected to the middle portion of the sleeve.
[0019] In some embodiments, the through hole has a size of 0.5 mm to 1 mm.

[0021] In some embodiments, a conduit is further connected to the end of the buffer channel close to the outlet, the conduit is connected to the dust collecting box, and a switch is provided on the conduit.
[0022] Beneficial effects of the dust removal device for cutting Chinese medicinal materials of the present invention:
[0023] The dust removal device for cutting Chinese medicinal materials of the present invention first transmits the Chinese medicinal dust generated in the Chinese medicinal material cutting chamber to the buffer channel through the first channel. The middle part of the buffer channel is provided with a bulging unit. When the dust flows through the bulging unit, the pressure of the air flow containing the Chinese medicinal dust decreases, so that the flow speed of the Chinese medicinal dust in the buffer channel is reduced and then the Chinese medicinal dust is deposited in the bulging unit, which plays the role of the first sedimentation of the Chinese medicinal dust. Then, the air flow with the remaining Chinese medicinal dust flows into the second flow channel. Since the second flow channel is vertically arranged and has a certain length, the Chinese medicinal dust can be deposited when flowing through the second flow channel by using gravity. The dust is deposited to the bottom of the second flow channel, which further reduces the Chinese medicinal dust and effectively reduces external discharge.
[0024] By reducing the emission of dust, the working environment of operators is improved and the impact on their health is reduced. The dust removal device has a simple design and is easy to operate, making it convenient for workers to perform daily maintenance and cleaning. In addition, due to the effective control of dust, production interruptions caused by dust problems are reduced, and overall production efficiency is improved. BRIEF DESCRIPTION OF THE DRAWINGS

[0032] Example 1
[0033] The dust removal device for cutting Chinese medicinal materials disclosed in this embodiment is as follows: Figure 1-2 As shown, including:
[0034] The first channel 1 is connected to the Chinese medicinal material cutting chamber 2, and an exhaust fan is provided at the connection between the first channel 1 and the Chinese medicinal material cutting chamber 2.
[0035] The dust generated during the cutting of Chinese medicinal materials is discharged through the first channel 1, and the exhaust fan plays an auxiliary role in the extraction.
[0036] The buffer channel 3 is placed horizontally, one end of the buffer channel 3 is an inlet 4, and the other end is an outlet 5, the inlet 4 is connected to the first channel 1, the outlet 5 faces outward, and a bulging unit 20 bulging outward is provided in the middle section of the buffer channel 3.
[0037] The transversely placed buffer channel 3 enables the dust-containing airflow to flow in the buffer channel 3 and gradually lower the dust contained in the airflow during the flow. Moreover, since the buffer channel 3 has a bulging unit 20, the dust in the airflow can be better settled under low pressure.
[0038] The second channel 6 extends in the vertical direction, the middle of the second channel 6 is connected to the outlet 5 of the buffer channel 3, one end of the second channel 6 is connected to the dust box 7, and the other end is the discharge port 8, and the discharge port 8 is connected to the vacuum pump.
[0039] The second channel 6 is arranged vertically, and the second channel 6 has a certain length, illustratively, the length is 2 to 3 meters, and the length is such that the airflow containing the remaining dust undergoes secondary sedimentation under the action of gravity.
[0040] In this embodiment, the calibers of the first channels 1 are uniformly arranged, and the caliber of the first channels 1 is not larger than the inlet 4 of the buffer channel 3 .
[0041] The caliber of the first channel 1 is controlled to be no larger than the inlet 4 of the buffer channel 3 , so as to facilitate guiding the flow channel in the Chinese medicinal material cutting cavity 2 into the buffer channel 3 .
[0042] In this embodiment, the bulging unit 20 includes a first truncated cone cover 10 and a second truncated cone cover 11. The expanded bottom surface of the first truncated cone cover 10 is integrally connected with the expanded bottom surface of the second truncated cone cover 11.
[0043] The side of the truncated cone cover is composed of a soft surface 18 and a hard surface 19. The soft surface 18 can be silicone, rubber, polyurethane. The hard surface 19 can be stainless steel, plastic and aluminum alloy.
[0044] The bulging unit 20 is designed to be composed of two truncated cone covers to form a bulging part, and the side of the truncated cone cover is composed of a soft surface 18 and a hard surface 19. The effect is: by compressing or stretching the bulging unit 20, the cross section of the bulging unit 20 can be made smaller or larger. Specifically, when the first truncated cone cover 10 and the second truncated cone cover 11 are compressed toward each other, the cross section of the bulging unit 20 becomes larger, so that the airflow is reduced, and the dust in the airflow can be better settled. On the contrary, when the first truncated cone cover 10 and the second truncated cone cover 11 are stretched back to back, the cross section of the bulging unit 20 becomes smaller, the airflow increases, and the airflow flow channel is promoted. Therefore, the buffer channel 3 can be compressed or stretched according to the actual air pressure of the buffer channel 3. Under the condition of ensuring the dust settling efficiency, the flow velocity of the airflow in the buffer channel 3 can be adjusted to improve the dust removal effect. For example, when the amount of cut Chinese medicinal materials is large and the dust density contained is high, the airflow pressure is reduced by compressing the buffer channel 3, and the dust is easily settled. On the contrary, when the amount of cut Chinese medicinal materials is small and the dust density contained is low, the air flow pressure is increased by stretching the buffer channel 3, thereby improving the air flow and the dust removal efficiency.
[0045] In this embodiment, the middle portion of the buffer channel 3 is connected in series by a plurality of bulging units 20 .
[0046] Since several units are connected, the airflow flows through multiple units, thereby improving the processing efficiency.
[0047] In this embodiment, the inlet 4 of the buffer channel 3 is provided with a solenoid valve 12 .
[0048] The solenoid valve 12 can control the on / off state of the buffer channel 3 and control the dust removal process.
[0049] In this embodiment, a pressure sensor 13 is disposed in the swelling unit 20 , and the pressure sensor 13 detects the pressure in the buffer channel.
[0050] The pressure sensor 13 is used to observe the air pressure in the buffer channel, and then adjust the expansion and contraction state of the buffer channel according to the pressure condition.
[0051] In this embodiment, a sleeve 14 is disposed in the second channel 6 , a through hole 15 is opened on the tube surface of the sleeve 14 , and the buffer channel 3 is connected to the middle part of the sleeve 14 .
[0052] The outlet 5 of the buffer channel 3 is directly connected to the middle of the sleeve 14, so that the airflow containing the residual dust first flows in the sleeve 14 and overflows from the through hole 15 of the sleeve 14. Under the further deceleration effect of the sleeve 14, the flow speed of the airflow decreases, and under the action of gravity, it can better sink to the bottom of the second channel 6 and be collected in the dust box 7.
[0053] In this embodiment, the size of the through hole 15 is 0.5 mm to 1 mm.
[0054] The size of the through hole 15 allows dust of the size to overflow, while large dust particles can settle directly in the sleeve 14, which can further avoid the problem of dust overflowing due to dust being too small.
[0055] In this embodiment, the discharge port 8 is provided with dust-absorbing cotton 16 , and the dust-absorbing cotton 16 covers the discharge port 8 .
[0056] The dust-absorbing cotton 16 is used to absorb the final dust, ensure the dust removal effect, and prevent dust from overflowing.
[0057] In this embodiment, the end of the buffer channel 3 close to the outlet 5 is further connected to a conduit 17 , the conduit 17 is connected to the dust collecting box 7 , and a switch is provided on the conduit 17 .
[0058] The conduit 17 allows the dust deposited on the buffer channel 3 to be recovered into the dust collecting box 7 through the conduit 17 .
