Abstract
Description
Technical Field
[0001] This utility model belongs to the field of pharmaceutical technology, specifically relating to a dust removal system and dust removal spray tower for a medicinal herb frying machine. Background Technology
[0002] Dust removal during the processing of medicinal herbs is a crucial step in the traditional Chinese medicine (TCM) processing procedure. Currently, machines are commonly used to stir-fry medicinal herbs. However, during the pre-treatment process, some fine particles or impurities may fall off the surface of the herbs, causing dust to be stirred up during stir-frying. This dust can pollute the environment and reduce the purity and quality of the TCM. Therefore, dust removal devices are generally installed during the stir-frying process to reduce the environmental harm caused by dust and ensure the quality of the TCM.
[0003] The existing dust removal devices have insufficient suction power and cannot meet the emission standards for exhaust gas. Therefore, it is necessary to design a dust removal device and system for the stir-frying machine with good dust removal effect to address the problems of the existing devices. Utility Model Content
[0004] This utility model provides a dust removal system and dust removal spray tower for a medicinal herb frying machine, which aims to solve the technical problem of poor dust removal effect of existing devices.
[0005] To solve the aforementioned technical problems, the present invention adopts the following technical solution:
[0006] A dust removal system for a medicinal herb roasting machine includes dust removal components and a spray tower.
[0007] The spray tower is connected to the herb-frying machine and the dust removal assembly on both sides, respectively.
[0008] The dust removal assembly includes a first pulse dust collector and an electrostatic adsorber. One end of the first pulse dust collector is connected to the spray tower, and the other end is connected to the electrostatic adsorber.
[0009] When adopting this technical solution, it should be noted that both pulse dust collectors and electrostatic precipitators are existing technologies, used for dust removal and odor removal respectively. In a pulse dust collector, gas enters the equipment through the inlet and is filtered through filter bags. Subsequently, pulse jet technology compresses air through pulse valves and sprays it onto the filter bags, causing them to shake violently and shake off the dust, which falls into the collection hopper. Electrostatic precipitators are based on the principle of a high-voltage electrostatic field. Odor molecules are polarized under the action of the high-voltage electrostatic field and are thus adsorbed onto the electrodes. In addition, the ozone and other active substances generated by the electrostatic precipitator can also oxidize and decompose odor molecules, thereby achieving odor removal. Since both are existing technologies and widely used in dust removal and odor removal, this application does not restrict their models and structures, and they can be purchased as needed.
[0010] Preferably, the dust removal assembly further includes a second pulse dust collector, and the first pulse dust collector, the electrostatic adsorber, and the second pulse dust collector are connected in sequence.
[0011] After adopting this technical solution, it should first be noted that the second pulse dust collector performs the final dust removal treatment on the gas passing through the electrostatic adsorber, thus achieving comprehensive and effective treatment of the dust generated during the stir-frying process.
[0012] It should also be noted that the filter bags in the first and second pulse dust collectors have the same pore size, meaning that the theoretical filtration effect of the first and second pulse dust collectors is the same. However, the air volume generated by the second pulse dust collector is lower than that of the first pulse dust collector. This is because the spray tower and the first pulse dust collector have already removed most of the dust, so the second pulse dust collector does not need a larger air volume to achieve filtration. The second pulse dust collector uses a frequency converter and a manual air valve to control the fan air volume to achieve energy saving. The structure and control method of this air volume control are also existing technologies, which are widely used in pulse dust collectors and will not be elaborated here.
[0013] Preferably, an activated carbon adsorber is connected after the second pulse dust collector, and the activated carbon adsorber has a discharge pipe at its upper end.
[0014] After adopting this technical solution, it should be noted that activated carbon has a high adsorption capacity and its porous structure can adsorb gas molecules. When the gas after being dusted by the second pulse dust collector passes through the activated carbon, the harmful gases and odor molecules in it will be adsorbed by the activated carbon, thus achieving the effect of smoke removal and improving the quality of the emitted gas.
[0015] Furthermore, the herb-frying machine is connected to the outside world through a pipe. The first pulse dust collector, the electrostatic adsorber, and the second pulse dust collector are respectively connected to the first slag discharge pipe, the second slag discharge pipe, and the third slag discharge pipe at their lower ends. The first slag discharge pipe, the second slag discharge pipe, the third slag discharge pipe, and the discharge pipe are respectively equipped with a second valve, a third valve, a fourth valve, and a fifth valve.
[0016] After adopting this technical solution, it should be noted that the second valve and the fourth valve control the ash discharge of the first pulse dust collector and the second pulse dust collector, respectively, and the fifth valve controls the emission of the gas after dust and smoke removal.
[0017] A dust removal spray tower for a medicinal herb stir-frying machine, the spray tower comprising a tower body and spray components.
[0018] The spray assembly is located inside the tower body.
[0019] The spray assembly includes at least one first spray pipe and at least one second spray pipe. The first spray pipe and / or the second spray pipe are connected to the inner wall of the tower body. The first spray pipe is arranged along the axial direction of the tower body, and the second spray pipe is perpendicular to the first spray pipe. The first spray pipe and the second spray pipe are provided with at least one nozzle. The first spray pipe and the second spray pipe are respectively connected to a water tank.
[0020] In this utility model, it should be noted that the smoke and dust generated when the herb roasting machine is roasting herbs are transported to the inside of the spray tower through a pipeline. During the process of the smoke and dust spreading inside the tower, the first spray pipe will spray water mist. The water mist combines with the dust particles to form large particle clusters, which finally fall to the bottom of the tower under the action of gravity and are then discharged in a concentrated manner.
[0021] Furthermore, it should be noted that in order to improve the binding effect of water mist and dust particles, thereby achieving better dust removal, a first spray pipe is installed along the axial direction of the tower body. This allows the water mist to be sprayed out radially along the tower body, making full contact with the dust spreading along the axial direction of the tower body, thus gradually improving the dust removal effect. In addition, a second spray pipe is installed perpendicular to the first spray pipe, meaning that the water mist sprayed from the second spray pipe is along the axial direction of the tower body. The first and second spray pipes work together to achieve comprehensive coverage of the interior of the tower body, ultimately achieving a good dust removal effect and effectively removing medium and large particles.
[0022] Preferably, the spray assembly further includes an annular pipe connected to the inner wall of the tower body.
[0023] The first spray pipe is connected to the annular pipe, and the first spray pipe is perpendicular to the annular pipe.
[0024] The second spray pipe is arranged radially along the annular pipe, and both ends of the second spray pipe are connected to the annular pipe.
[0025] After adopting this technical solution, it should be noted that the inner diameter of the annular pipe is larger than the inner diameter of the first spray pipe and the second spray pipe. The annular pipe is used to connect the first spray pipe and the second spray pipe, improving the compactness of the spray structure. On the other hand, since the inner diameter of the annular pipe is larger than that of the first spray pipe and the second spray pipe, the flow velocity of water will increase when it flows through the annular pipe into the first spray pipe and the second spray pipe, thereby increasing the water mist spray pressure and making the dust removal effect better.
[0026] Preferably, the outer wall of the annular pipe is connected to a connecting ring, which is connected to the inner wall of the tower body to improve the stability of the spray pipe.
[0027] Preferably, four first spray pipes are provided, and one second spray pipe is provided.
[0028] Four first spray pipes are evenly distributed on the annular pipe, and the nozzles on each first spray pipe face the axis of the tower body. The first spray pipes are connected to the lower part of the annular pipe.
[0029] The nozzles on the second spray pipe all face downwards.
[0030] After adopting this technical solution, it should be noted that the first spray pipe is set every 90 degrees along the annular pipe to achieve full coverage of the inside of the spray tower. In this utility model, the nozzle is existing technology, and nozzles with different spray angles can be selected according to the actual inner diameter of the tower.
[0031] Furthermore, in this invention, the annular pipe can be placed at the lower end of the tower body, while the first spray pipe is placed at the upper end of the annular pipe, and the nozzles on the second spray pipe are set upwards. Through the cooperation of the first and second spray pipes, the dust inside the tower body can be effectively removed from multiple angles without dead angles, thus reducing the pressure of subsequent dust removal.
[0032] Preferably, the annular pipe is connected to a water inlet pipe, the water inlet pipe is connected to the water tank, and a water pump is installed on the water inlet pipe.
[0033] After adopting this technical solution, it should be noted that the water in the water tank is pumped into the annular pipe by a water pump and given initial pressure. The water then enters the first spray pipe and the second spray pipe through the annular pipe, thereby spraying out water mist.
[0034] Furthermore, the lower part of the tower body is provided with an air inlet pipe and a liquid outlet pipe, both of which are connected to the interior of the tower body. The air inlet pipe is located above the liquid outlet pipe, and the annular pipe is located at the upper end of the interior of the tower body. The first spray pipe extends downward to the air inlet pipe.
[0035] The drain pipe is equipped with a first valve.
[0036] After adopting this technical solution, it should be noted that the flue gas enters the lower part of the tower body through the inlet pipe. During the rising process of the flue gas, it combines with the mist sprayed from the first spray pipe to remove dust. The second spray pipe is set at the upper part of the tower body to spray the flue gas that rises into the spray range of the second spray pipe again, thereby achieving a better spraying effect. During this process, the water mist that combines with the dust falls to the lower part of the tower body and can be discharged from the drain pipe at regular intervals.
[0037] It should also be noted that the air inlet pipe is located above the drain pipe, and the first spray pipe extends to the air inlet pipe, so that the sewage is staggered from the first spray pipe and does not come into contact with it.
[0038] Preferably, a collecting hood is connected to the upper end of the tower body, and an exhaust pipe is connected to the collecting hood. The gas after spraying and dust removal enters the next process through the exhaust pipe.
[0039] In this utility model, the stir-frying machine, spray tower, first pulse dust collector, electrostatic adsorber, second pulse dust collector and activated carbon adsorber are connected by pipelines. The valves and water pumps are existing technologies, and appropriate valves and water pumps can be selected according to the actual situation.
[0040] The dust removal process of this utility model:
[0041] Dust Removal by Spraying: The smoke and dust generated during the stir-frying of herbs in the stir-frying machine enter the lower end of the spray tower through pipes and air inlet pipes. As the smoke and dust rise, they combine with the water mist sprayed from the first spray pipe. The dust and other particulate matter in the smoke and dust fall to the bottom of the tower under the action of gravity. After the smoke and dust rise into the spray range of the second spray pipe, they will be sprayed again. The first spray pipe and the second spray pipe work together to achieve a good removal effect on medium and large dust particles.
[0042] Pulse dust removal and electrostatic adsorption deodorization: After spray dust removal, the gas enters the first pulse dust collector through a pipeline to further remove the remaining medium and large particles. The gas then enters the electrostatic adsorber, where a high-voltage electrostatic field removes odors. After passing through the electrostatic adsorber, the gas enters the second pulse dust collector to further remove the remaining particles. Finally, the gas enters the activated carbon adsorber through a pipeline, where the high adsorption capacity of activated carbon removes smoke from the gas, improving the quality of the emitted gas.
[0043] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are:
[0044] 1. The present invention provides a dust removal system and dust removal spray tower for a medicinal herb frying machine. By setting a first spray pipe along the axial direction of the tower body, water mist is sprayed out in the radial direction of the tower body, making full contact with the smoke and dust that diffuses in the axial direction of the tower body. By setting a second spray pipe perpendicular to the first spray pipe, the sprayed water mist is made to spray along the axial direction of the tower body. The first spray pipe and the second spray pipe work together to achieve a thorough coverage of the interior of the tower body without dead angles, and finally achieve a good dust removal effect, effectively removing medium and large particles.
[0045] 2. The dust removal system and dust removal spray tower for a medicinal herb frying machine provided by this utility model, by setting an annular pipe, serves two purposes: firstly, it connects the first spray pipe and the second spray pipe, improving the compactness of the spray structure; secondly, since the inner diameter of the annular pipe is larger than that of the first and second spray pipes, the flow velocity of water will increase when it flows through the annular pipe into the first and second spray pipes, thereby increasing the water mist spray pressure and improving the dust removal effect.
[0046] 3. The dust removal system and dust removal spray tower for a medicinal herb frying machine provided by this utility model, by setting an annular pipe at the upper end of the tower body, the dust is removed by combining with the mist sprayed from the first spray pipe during the rising process of the smoke and dust, and by setting a second spray pipe at the upper end of the tower body, the smoke and dust that rise into the spray range of the second spray pipe are sprayed again, thereby achieving a better spraying effect.
[0047] 4. The dust removal system and dust removal spray tower for a medicinal herb frying machine provided by this utility model optimizes the dust removal process by sequentially setting a first pulse dust collector, an electrostatic adsorber, and a second pulse dust collector, and ultimately achieves comprehensive and effective treatment of the smoke and dust generated during the medicinal herb frying process.

In addition, the terms "first," "second," and "third," etc., are only used to distinguish descriptions and should not be construed as indicating or implying relative importance.
[0057] The following is combined Figures 1-4 This utility model will be described in detail.
[0058] Example 1
[0059] A dust removal system for a medicinal herb stir-frying machine, such as Figure 1 As shown, it includes dust removal components and spray tower 2.
[0060] The spray tower 2 is connected to the stir-frying machine 1 and the dust removal component on both sides, respectively.
[0061] The dust removal assembly includes a first pulse dust collector 4 and an electrostatic adsorber 5. One end of the first pulse dust collector 4 is connected to the spray tower 2, and the other end is connected to the electrostatic adsorber 5.
[0062] In this embodiment, the pulse dust collector mainly removes dust, while the electrostatic adsorber 5 mainly removes odors. The two work together to improve the dust removal quality.
[0063] Example 2
[0064] The difference between this embodiment and Embodiment 1 is that, as Figure 1 As shown, the dust removal assembly also includes a second pulse dust collector 6, and the first pulse dust collector 4, the electrostatic adsorber 5 and the second pulse dust collector 6 are connected in sequence.
[0065] In this embodiment, the second pulse dust collector 6 performs the final dust removal treatment on the gas passing through the electrostatic adsorber 5, ultimately achieving comprehensive and effective treatment of the smoke and dust generated during the frying process. The filter bags in the first pulse dust collector 4 and the second pulse dust collector 6 have the same pore size, meaning that the theoretical filtration effect of the first pulse dust collector 4 and the second pulse dust collector 6 is the same. However, the air volume generated by the second pulse dust collector 6 is lower than that of the first pulse dust collector 4. The reason for this is that the spray tower 2 and the first pulse dust collector 4 have already removed most of the dust, so the second pulse dust collector 6 does not need a larger air volume to achieve filtration, thus saving energy.
[0066] Example 3
[0067] The difference between this embodiment and Embodiment 2 is that, as Figure 1 As shown, the second pulse dust collector 6 is also connected to an activated carbon adsorber 7, and the activated carbon adsorber 7 is provided with an exhaust pipe 18 at its upper end.
[0068] The herb-frying machine 1 is connected to the outside world through a pipe. The first pulse dust collector 4, the electrostatic adsorber 5, and the second pulse dust collector 6 are respectively connected to the lower end of the first slag discharge pipe 15, the second slag discharge pipe 16, and the third slag discharge pipe 17. The first slag discharge pipe 15, the second slag discharge pipe 16, the third slag discharge pipe 17, and the discharge pipe 18 are respectively equipped with a second valve 10, a third valve 11, a fourth valve 12, and a fifth valve 13.
[0069] In this embodiment, activated carbon has a high adsorption capacity and its porous structure can adsorb gas molecules. When the gas after being dusted by the second pulse dust collector 6 passes through the activated carbon, the harmful gases and odor molecules in it will be adsorbed by the activated carbon, achieving the effect of smoke removal and improving the quality of the emitted gas.
[0070] In addition, the second valve 10 and the fourth valve 12 control the ash discharge of the first pulse dust collector 4 and the second pulse dust collector 6, respectively, and the fifth valve 13 controls the emission of the gas after dust and smoke removal.
[0071] Example 4
[0072] A dust removal spray tower for a medicinal herb stir-frying machine, such as Figures 2-4 As shown, the spray tower 2 includes a tower body 201 and a spray assembly 19.
[0073] The spray assembly 19 is located inside the tower body 201.
[0074] The spray assembly 19 includes at least one first spray pipe 1902 and at least one second spray pipe 1903. The first spray pipe 1902 and / or the second spray pipe 1903 are connected to the inner wall of the tower body 201. The first spray pipe 1902 is arranged along the axial direction of the tower body 201. The second spray pipe 1903 is perpendicular to the first spray pipe 1902. At least one nozzle 20 is provided on the first spray pipe 1902 and the second spray pipe 1903. The first spray pipe 1902 and the second spray pipe 1903 are respectively connected to the water tank 3.
[0075] The lower part of the tower body 201 is provided with an air inlet pipe 204 and a liquid drain pipe 14, both of which are connected to the interior of the tower body 201.
[0076] In this embodiment, a first spray pipe 1902 is provided along the axial direction of the tower body 201, so that water mist is sprayed out in the radial direction of the tower body 201, making full contact with the smoke and dust that diffuses in the axial direction of the tower body 201, thereby gradually improving the dust removal effect. In addition, a second spray pipe 1903 is set perpendicular to the first spray pipe 1902, that is, the water mist sprayed from the second spray pipe 1903 is along the axial direction of the tower body 201. The first spray pipe 1902 and the second spray pipe 1903 cooperate with each other to achieve a thorough coverage spray inside the tower body 201, ultimately achieving a good dust removal effect and effectively removing medium and large particles.
[0077] Example 5
[0078] The difference between this embodiment and embodiment 4 is that, as Figure 3 , Figure 4 As shown, the spray assembly 19 also includes an annular pipe 1901, which is connected to the inner wall of the tower body 201.
[0079] The first spray pipe 1902 is connected to the annular pipe 1901, and the first spray pipe 1902 is perpendicular to the annular pipe 1901.
[0080] The second spray pipe 1903 is arranged radially along the annular pipe 1901, and both ends of the second spray pipe 1903 are connected to the annular pipe 1901.
[0081] The outer wall of the annular pipe 1901 is connected to a connecting ring 21, which is connected to the inner wall of the tower body 201.
[0082] The first spray pipe 1902 has four parts, and the second spray pipe 1903 has one part.
[0083] Four first spray pipes 1902 are evenly distributed on the annular pipe 1901, and the nozzles 20 on each first spray pipe 1902 are all facing the axial direction of the tower body 201. The first spray pipes 1902 are connected to the lower part of the annular pipe 1901.
[0084] The nozzles 20 on the second spray pipe 1903 all face downwards.
[0085] The annular pipe 1901 is connected to a water inlet pipe 205, which is connected to the water tank 3. A water pump 9 is installed on the water inlet pipe 205.
[0086] The air inlet pipe 204 is located above the drain pipe 14, the annular pipe 1901 is located inside the upper part of the tower body 201, and the first spray pipe 1902 extends downward to the air inlet pipe 204.
[0087] The drain pipe 14 is equipped with a first valve 8.
[0088] In this embodiment, the inner diameter of the annular pipe 1901 is larger than the inner diameter of the first spray pipe 1902 and the second spray pipe 1903. The annular pipe 1901 serves two purposes: firstly, it connects the first spray pipe 1902 and the second spray pipe 1903, improving the compactness of the spray structure; secondly, because the inner diameter of the annular pipe 1901 is larger than that of the first spray pipe 1902 and the second spray pipe 1903, the flow velocity of water will increase when it flows through the annular pipe 1901 into the first spray pipe 1902 and the second spray pipe 1903, thereby increasing the water mist spray pressure and improving the dust removal effect.
[0089] In addition, the first spray pipe 1902 is set at 90 degrees along the annular pipe 1901 to achieve full coverage of the inside of the spray tower 2. The flue gas enters the lower part of the tower body 201 from the air inlet pipe 204. During the rise of the flue gas, it combines with the mist sprayed from the first spray pipe 1902 to remove dust. The second spray pipe 1903 is set at the upper part of the tower body 201 to spray the flue gas that rises into the spray range of the second spray pipe 1903 again, thereby achieving a better spray dust removal effect.
[0090] The dust removal process of this utility model is as follows:
[0091] Dust Removal by Spraying: The smoke and dust generated during the stir-frying of herbs in the stir-frying machine 1 enters the lower end of the spray tower 2 through the pipe and air inlet pipe 204. During the rise of the smoke and dust, it combines with the water mist sprayed from the first spray pipe 1902. The dust and other particulate matter in the smoke and dust fall to the bottom of the tower body 201 under the action of gravity. After the smoke and dust rises into the spray range of the second spray pipe 1903, the smoke and dust will be sprayed again. The first spray pipe 1902 and the second spray pipe 1903 work together to achieve a good removal effect on medium and large dust particles.
[0092] Pulse dust removal and electrostatic adsorption deodorization: After spray dust removal, the gas enters the first pulse dust collector 4 through a pipeline to further remove the remaining medium and large particles. The gas after dust removal enters the electrostatic adsorber 5, where the odor is removed by a high-voltage electrostatic field. The gas after passing through the electrostatic adsorber 5 enters the second pulse dust collector 6 to further remove the remaining particles. After that, the gas enters the activated carbon adsorber 7 through a pipeline, where the high adsorption capacity of activated carbon removes the smoke in the gas, improving the quality of the emitted gas.
[0093] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
