If not treated, it will cause the deterioration of the production workshop environment and affect the health of the workers who feed the materials. At the same time, it will cause a considerable burden on the cleaning of the production workshop.

[0003] A dust removal system for Chinese medicine extraction and feeding mentioned in publication number CN110180281A collects the dust not sucked in by the side flow device through the electric fan inside the wind duct, and the sucked dust is also sent into the dust removal pipe connected to the wind duct.

[0057] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in 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.

[0058] It should be noted that the directional words such as "upper" and "lower" mentioned below are defined based on the drawings in the specification.

[0059] The core of the utility model is to provide a dust removal, purification and feeding equipment, which can extract smoke and dust generated during the feeding process from the equipment, thereby purifying the production environment, and the equipment occupies a small area.

[0060] Please refer to Figure 1 A dust removal and purification feeding equipment includes a frame 1, an observation door 2, a lifting door 3, a detection device 4, a one-way air inlet 5, a feeding component 6, a vibration device 7, a purge device 8, a dust collecting device 9 and a control device.

[0061] Specifically, the lifting door 3, the detection device 4, the vibration device 7, the purge device 8 and the dust collecting device 9 are all connected to the control device. The frame 1 is a box-type structure, so that the equipment is in a sealed state on all sides to achieve dust-free feeding. The frame 1 is provided with an observation door 2 and a lifting door 3 in the circumference. The observation door 2 is set at a 90-degree angle to the lifting door 3. The lifting door 3 moves up and down along the height direction of the frame 1. The observation door 2 can be opened and closed on the frame 1, which is convenient for opening and maintaining the internal structure. The frame 1 is provided with a detection device 4 and a one-way air inlet 5. The detection device 4 is arranged at the bottom of the lifting door 3. The one-way air inlet 5 is provided to supplement air inside the feeding port. When the detection device 4 detects the turnover basket ready for feeding, it sends a signal to the control device, and the control device controls the lifting door 3 to open upward to ensure normal feeding of the turnover basket.

[0062] The unloading assembly 6 is arranged at the bottom of the frame 1, and the top of the unloading assembly 6 is lower than the bottom of the lifting door 3 to avoid interference between the unloading assembly 6 and the lifting door 3. The bottom of the unloading assembly 6 is a contracted unloading port. Normal feeding is achieved by setting the unloading assembly 6. A vibrating device 7 is provided at the bottom of the unloading assembly 6. When the lifting door 3 is opened, the control device controls the vibrating device 7 to start, so that the material can be smoothly discharged from the unloading port. The material remaining on the inner wall of the unloading assembly 6 can also be vibrated into the unloading port to avoid the material remaining in dead corners and other positions to prevent mixed batches. A purge device 8 is provided at the top of the unloading assembly 6 with an outlet facing the lifting door 3. The control device controls the purge device 8 to purge the inside of the turnover basket by compressed gas. On the one hand, it cleans the floating dust inside the turnover basket, and on the other hand, it blows down the material remaining in the turnover basket. The dust collecting device 9 is arranged at the top of the frame 1 and is connected to the inside of the frame 1. The control device controls the dust collecting device 9 to start, and the air in the equipment forms a negative pressure cycle, thereby playing a role in dust removal and purification.

[0063] Among them, the vibrating device 7 can be replaced by a dragon to avoid material residue, but the equipment will be more complicated. In actual life, there is no restriction on the type and location of the vibrating device 7, as long as the above technical effect can be achieved. In this embodiment, the equipment is made of stainless steel, which is not easy to rust and is easy to maintain. In actual life, there is no restriction on this.

[0064] It is particularly noted that a one-way air inlet 5 is installed on the frame 1 opposite to the lifting door 3. The device has a one-way effect and can only allow external air to flow into the device, but cannot allow dust in the device to overflow. Its function is to replenish air inside the device and form a negative pressure circulation for the air in the device through the dust collecting device 9 on the top, thereby playing a role in dust removal and purification.

[0065] The dust removal, purification and feeding equipment arranged in the above manner has a simple structure and is easy to maintain. While achieving "dust-free" feeding, it can also avoid material residue and mixed batches.

[0066] In the above embodiment, a one-way feeding device 10 is provided at the bottom of the feed opening.

[0067] It should be noted that, by providing the one-way feeding device 10, the material can be normally fed into the extraction tank, and at the same time, the dust that falls into the extraction tank can be prevented from rising into the equipment.

[0068] Please refer to Figure 2 The one-way feeding device 10 includes a feeding pipeline 101, a flap 102 and a spring return structure 103. The feeding pipeline 101 is arranged at the bottom of the discharge port and is connected to the discharge port. One side of the flap 102 is connected to the feeding pipeline 101 through a hinge so that the flap 102 can rotate along the height direction of the feeding pipeline 101. The spring return structure 103 is arranged in the feeding pipeline 101, and one end of the spring return structure 103 is connected to the rotating end of the flap 102.

[0069] It can be understood that the flap 102 is fixed to the inner side of the feed pipe 101 with bolts through a hinge mechanism. The flap 102 is located below the discharge port and above the extraction tank. When the material falls onto the flap 102 under the action of gravity, the flap will be pressed down by its gravity to make the material continue to fall. When the material leaves the flap 102, the spring return structure 103 will pull the flap 102 back to its original position. The original position can just seal the feed pipe 101, so as to prevent the dust that falls into the extraction tank from rushing up into the equipment.

[0070] Among them, in this embodiment, the feed pipeline 101 is a rectangular pipe, but in real life, there is no limitation to this, as long as the above technical effects can be achieved.

[0071] Furthermore, a Teflon slide plate is provided on the surface of the flap 102 .

[0072] It should be noted that a Teflon slide plate is also installed on the flap 102, the purpose of which is to reduce resistance so that the material can slide smoothly. In this embodiment, a Teflon slide plate is provided on the surface of the flap 102, but in real life, there is no limitation to this, as long as the above-mentioned technical effect can be achieved.

[0073] In the above embodiment, a door stopper 11 is provided at the bottom of the observation door 2, a safety door switch 12 is provided at the top of the observation door 2, the safety door switch 12 is connected to the control device, and a sealing strip is provided around the observation door 2.

[0074] It can be understood that during the feeding production process, the observation door 2 is always in a closed state. When it is opened, it will trigger the safety door switch 12 on the top, and then the feeding port will terminate all actions. The only thing that will not be terminated is the dust collection device 9 on the top. This can avoid safety accidents caused by sudden human intervention during the production process, and can also avoid the dust inside the observation door 2 from being deposited and flowing into the surrounding production environment when it is opened.

[0075] On the basis of the above embodiment, the lifting door 3 is lifted and moved by the cylinder 13 . The cylinder 13 is arranged on the top of the frame 1 and connected to the control device. A limiting device 14 is arranged on the top of the lifting door 3 .

[0076] It should be noted that the control device controls the operation of the cylinder 13 to drive the lifting door 3 to move up or down. When the lifting door 3 rises to a certain height, the limiting device 14 will limit the lifting door 3 to prevent the lifting door 3 from continuing to rise.

[0077] Please refer to Figure 3 The limiting device 14 includes a guide plate 141, a guide roller 142 and a guide shaft 144. The guide plate 141 is arranged on the frame 1, and the guide plate 141 is set to be U-shaped. The opening of the guide plate 141 is set toward the lifting door 3. The guide roller 142 is arranged in the guide plate 141 and moves along the guide plate 141. A bearing 143 is arranged in the guide roller 142. One end of the guide shaft 144 is connected to one end of the bearing 143, and the other end of the guide shaft 144 is connected to the opening and closing door. The other end of the bearing 143 is provided with a retaining ring 145.

[0078] It is understandable that when the cylinder 13 drives the lifting door 3 to move up and down, a rotational force will be generated, which is not conducive to the vertical and stable operation of the door. To avoid this situation, the guide plate 141 installed on the frame 1 is used as the main guide, and the guide shaft 144 is connected to the lifting door 3 as a whole through the screw 153. A bearing 143 is installed at the other end of the guide shaft 144, and a retaining ring 145 is installed at the end of the bearing 143 to prevent the bearing 143 from detaching. The bearing 143 is installed in the guide roller 142, and the guide roller 142 is located inside the guide plate 141. During operation, the gap between the guide roller 142 and the guide plate 141 is small, so the rotation of the lifting door 3 is limited, so that it can only move up and down along the vertical direction of the guide plate 141.

[0079] Among them, the lifting door 3 can use a cylinder 13 with a guiding function, which can simplify the design of the lifting door 3. The lifting door 3 can also be lifted by an electric motor to move up and down to complete the opening and closing. There is no restriction on this as long as the above-mentioned technical effect can be achieved.

[0080] As a preferred embodiment, the dust collecting device 9 includes a dust collecting hood 91, a pipeline 92 and an axial flow fan 93. The dust collecting hood 91 is arranged at the top of the frame 1, and the dust collecting hood 91 is an inverted cone funnel shape. The pipeline 92 is arranged at the top of the dust collecting hood 91 and is connected to the dust collecting hood 91. The axial flow fan 93 is arranged in the pipeline 92 and is connected to the control device.

[0081] It should be noted that the dust collecting device 9 is composed of an axial flow fan 93, a pipeline 92 and a dust collecting hood 91. The dust collecting hood 91 is in the shape of an inverted cone funnel and is installed on the top of the frame 1. An axial flow fan 93 is installed in its internal pipeline 92, one end of which is installed on the top of the equipment, and the other end is connected to an outdoor dust removal and purification device through a stainless steel pipeline 92. The negative pressure and wind generated by the axial flow fan 93 extract the dust, impurities, etc. generated during the cleaning process from the equipment to ensure the relative cleanliness of the interior of the equipment and achieve the effect of "dust-free" feeding.

[0082] In the above case, a sound absorbing device 15 is provided inside the frame 1 .

[0083] It is understandable that the sound absorbing device 15 is provided in the frame 1 to reduce noise and sound insulation, improve the quality of the equipment, and reduce the impact of noise generated during the production process on the environment.

[0084] Please refer to Figure 4 The sound absorbing device 15 includes a sound absorbing cotton 151 and two stainless steel sealing covers 152, wherein one stainless steel sealing cover 152 is bonded to one side of the sound absorbing cotton 151 having adhesive backing, and the other side of the sound absorbing cotton 151 is fixed to the frame through another stainless steel sealing cover 152 and screws 153.

[0085] It should be noted that the sound-absorbing cotton 151 is pasted on the stainless steel sealing cover 152 by means of the adhesive backing, and then another layer of stainless steel sealing cover 152 is installed on the surface of the sound-absorbing cotton 151 without adhesive backing, and the sound-absorbing cotton 151 is placed inside the two layers of stainless steel sealing cover 152, and the stainless steel sealing cover 152 is fixed to the frame 1 by screws 153. The role of the sound-absorbing cotton 151 is to play a sealing role on the one hand, further avoiding the leakage of dust generated during feeding, and on the other hand, it plays a role in noise reduction and sound insulation, improving the quality of the equipment and reducing the impact of noise generated during the production process on the environment.

[0086] In summary, the dust removal and purification feeding equipment provided by the utility model, when the detection device 4 detects the turnover basket ready for feeding, will control the lifting door 3 to open upwards, and at the same time, the dust collecting device 9 installed on the top of the frame 1 is also opened, which is driven by the axial flow fan 93 to generate negative pressure inside the equipment, and the dust generated during feeding is extracted from the equipment, and the material in the turnover basket will be thrown onto the feeding component 6. At the same time as the material is fed, the vibration device 7 installed on the feeding component 6 will also be started, the purpose of which is to gradually move the material remaining on the inner wall of the feeding component 6 into the feeding port through vibration, so as to avoid the material remaining in dead corners and other locations, and prevent mixed batches.

[0087] When the turnover basket has completed feeding, the purging device 8 installed on both sides of the unloading component 6 will blow the inside of the turnover basket through compressed air. On the one hand, it can clean the floating dust inside the turnover basket, and on the other hand, it can blow down the materials remaining inside the turnover basket. When the turnover basket leaves the feeding port, the lifting door 3 will be closed under the drive of the cylinder 13. At this time, the dust collecting device 9 will continue to run for a period of time and then stop. The purpose is to further purify the air in the feeding port.

[0088] The equipment is reasonably designed. While achieving "dust-free" feeding, it also has a noise reduction function, which is conducive to optimizing the production environment. The lifting door 3 driven by the cylinder 13 has a simple structure and does not require maintenance. The linkage control can effectively prevent the dust inside the equipment from flowing into the production environment. The dust collection and dust removal are designed separately, so that the feeding equipment structure is relatively simple and easy to maintain, while improving the dust removal efficiency. A vibration device is designed to further prevent the material from remaining on the surface of the conical feeding port through vibration, thereby avoiding material residue and mixed batches. A one-way feeding device 10 is installed between the feeding port and the extraction tank, which is connected to the extraction tank through a hinge and a spring reset structure 10. 3 makes it open and close automatically, no additional mechanical device is needed, the structure is simple, and the dust in the extraction tank is prevented from rushing up into the equipment, further reducing the pollution to the working environment; a safety door switch 12 is designed, and the internal situation of the equipment can be checked through the observation door 2 at ordinary times. In special circumstances, the observation door 2 can be opened to intervene in the feeding. When the observation door 2 is opened, the feeding program stops automatically, and only the dust collecting device 9 is running all the time to avoid dust leakage; this equipment can be used alone or in multiple groups, so it can be used in assembly line production, connecting the front and rear stations, running fully automatically, without human intervention, and greatly improving production efficiency.

[0089] The various embodiments in this specification are described in a progressive manner, and each embodiment focuses on the differences from other embodiments. The same or similar parts between the various embodiments can be referenced to each other.

This article uses specific examples to illustrate the principle and implementation method of the utility model. The description of the above embodiment is only used to help understand the method and core idea of ​​the utility model. It should be pointed out that for ordinary technicians in this technical field, without departing from the principle of the utility model, the utility model can also be improved and modified, and these improvements and modifications also fall within the scope of protection of the claims of the utility model.
