Description

Technical Field

[0001] The utility model relates to the field of medicinal material drying equipment, in particular to an open drying box. Background Art

[0002] In the production process of Chinese medicinal materials, after the processes of cleaning, trimming, cutting, and stir-frying, the medicinal materials need to be dried. The purpose of drying is to remove moisture, inhibit the activity of enzymes, prevent the decomposition of effective ingredients, and facilitate long-term storage for future use. It should be understood that drying medicinal materials is a very important link in the entire medicinal material processing process. There are many ways to dry them, and corresponding drying measures are generally taken according to the different types of Chinese medicinal materials. For example, an open drying device is required for the drying of raw materials such as roots and stems of some plants, as well as semi-finished and finished medicinal materials. The open drying device is mostly composed of an external hot air blower device and an oven. The heat is brought into the oven in the form of hot air through the external hot air blower device, thereby drying the medicinal materials inside the oven.

[0003] The inventors discovered during their research that the open drying ovens of the prior art have at least the following disadvantages:

[0004] When the medicinal materials are spread flat on the hollow plate, the medicinal materials are in a static state, and the bottom of the medicinal materials is always in contact with the hollow plate. The contact area with the hot air is small, the drying uniformity is poor, and the drying efficiency is low. Utility Model Content

[0005] The purpose of the present invention includes, for example, providing an open drying box that can improve drying efficiency.

[0006] The embodiment of the present utility model can be implemented as follows:

[0007] In a first aspect, the utility model provides an open drying box, comprising:

[0008] A box body, a supporting frame, a blower, an exhaust hood and a driving mechanism; the box body is provided with a chamber with an opening, and an air supply hole is provided at the bottom of the chamber; the blower is connected to the air supply hole; the supporting frame is installed on the box body and is located above the air supply hole; the exhaust hood is installed above the opening; the driving mechanism is installed on the box body, and the driving mechanism is connected to the supporting frame to drive the supporting frame to rotate.

[0009] In an optional embodiment, the exhaust hood includes a hood body, an exhaust duct and a telescopic device, the hood body is installed above the opening; the exhaust duct and the telescopic device are both connected to the hood body; the telescopic device is used to be installed on the ceiling; the telescopic device is used to drive the hood body to rise and fall to adjust the distance between the hood body and the opening.

[0010] Based on this solution, the cover body is positioned on the ceiling via a telescopic mechanism. The telescopic mechanism can drive the cover body up and down, adjusting the distance between the cover body and the box body, and therefore the distance between the cover body and the medicinal materials on the support rack. This allows for adaptive adjustment of the suction speed and efficiency according to different scenarios, providing flexibility. Furthermore, the suction pipe can be connected to a negative pressure pump, making connection quick and easy.

[0011] In an optional embodiment, the telescoping device includes a winch and a cable, the winch is used to be fixed to the ceiling, one end of the cable is connected to the winch, and the other end of the cable is connected to the cover body, and the winch is used to adjust the winding length of the cable to adjust the height of the cover body relative to the box body.

[0012] Based on the above scheme, when the height of the cover body needs to be adjusted, the winch is started, the winch's shaft rotates, and the cable is wrapped around the shaft, shortening the length of the cable between the shaft and the cover body, and the cover body rises; similarly, when the shaft is reversed to unwrap the cable, the length of the cable between the shaft and the cover body is increased, and the cover body descends, making the operation flexible.

[0013] In an optional embodiment, a plurality of gas supply holes are provided at the bottom of the box body, and an air collecting hood is installed at the bottom of the box body, the air collecting hood is connected to all the gas supply holes at the same time, and a connector is provided on the air collecting hood, and the connector is connected to the air pump.

[0014] Based on the above solution, by setting up multiple air holes, more hot air can enter the bottom of the medicinal materials, so that the hot air is distributed over a wide area. The hot air passes through the medicinal materials from multiple positions, drying the medicinal materials and improving the drying efficiency.

[0015] In an optional embodiment, the supporting frame includes two frames arranged opposite to each other, both of which are connected to the driving mechanism, and the driving mechanism is used to simultaneously drive the two frames to rotate relative to the box body; the frame located on the upper layer of the two frames is detachably matched with the driving mechanism.

[0016] Based on the above scheme, the two racks are arranged relative to each other, the rack at the bottom can carry the medicinal materials, and the rack at the top can be removed when the medicinal materials are drying to prevent the upper rack from blocking the top of the medicinal materials. When the medicinal materials need to be reversed, that is, when the bottom of the medicinal materials can directly contact the hot air, the upper rack is installed on the driving mechanism and is located above the lower rack, and the two racks cooperate to clamp the medicinal materials. Then, the driving mechanism is started, and the driving mechanism drives the two racks to flip, so that the lower rack flips to the top and the upper rack flips to the bottom. Then, the rack that has been rotated up and is located on the upper layer is removed, so that the bottom surface of the medicinal materials that was originally in contact with the lower rack is exposed, which can directly contact with the hot air, thereby improving the drying effect.

[0017] In an optional embodiment, the frame body includes a grid body, a first connecting shaft sleeve and a second connecting shaft sleeve, the first connecting shaft sleeve and the second connecting shaft sleeve are respectively installed on opposite sides of the grid body, the first connecting shaft sleeve and the second connecting shaft sleeve are coaxially arranged, the first connecting shaft sleeve is provided with a first limiting column; the second connecting shaft sleeve is provided with a second limiting column;

[0018] The first and second mounting grooves with the notches facing upwards are provided on the opposite side walls of the box body, and the first connecting shaft sleeve and the second connecting shaft sleeve are rotatably installed in the first and second mounting grooves respectively; the driving mechanism includes a driver, a mounting shaft and a driving shaft, and the driver is fixed to the box body; two first limiting grooves are provided on the mounting shaft, and the mounting shaft is located between the two first connecting shaft sleeves, and the two first limiting columns are respectively inserted in the two first limiting grooves; two second limiting grooves are provided on the driving shaft, and the driving shaft is located between the two second connecting shaft sleeves, and the two second limiting columns are respectively inserted in the two second limiting grooves; the driving shaft is fixed to the driver, and the driver is used to drive the driving shaft to rotate.

[0019] Based on the above solution, the structure of the frame is simple. The first connecting sleeve cooperates with the mounting shaft, and the second connecting sleeve cooperates with the drive shaft. When the motor is started, the drive shaft can transmit torque to the second connecting sleeve, thereby driving the two-layer frame to rotate together. In addition, the first connecting sleeve on the other side of the two frames is combined with the mounting shaft, and the mounting shaft plays a role in supporting and transmitting torque. The rotation of the two-layer frame is smooth and reliable. In addition, when the frame is in a horizontal state, the upper frame can move directly upward, the first limit column and the first limit slot are disengaged, and the second limit column and the second limit slot are disengaged, so that the upper frame can be directly removed, which is easy to operate.

[0020] In an optional embodiment, the grid body has a first side surface and a second side surface that are opposite to each other, the first side surface is used for contacting the medicinal material, and the first connecting sleeve and the second connecting sleeve are both protruding from the second side surface.

[0021] Based on the above solution, by arranging the first connecting sleeve and the second connecting sleeve on the second side surface, the distance between the first side surfaces of the two-layer frame can be reduced, thereby better clamping the medicinal materials.

[0022] In an optional embodiment, the first connecting sleeve includes a sealing plate and an arc plate, the sealing plate is fixed to the second side surface, the arc plate is fixed to the sealing plate, and the first limiting column is fixed to the inner arc surface of the arc plate; the inner arc surface cooperates with the outer peripheral surface of the mounting shaft.

[0023] Based on the above solution, the arc-shaped plate and the grid body are connected by the sealing plate. The contact area between the sealing plate and the grid body is large, and the connection structure is firm and reliable.

[0024] In an optional embodiment, the frame further includes a handle, and the handle is fixed on the second side surface.

[0025] Based on the above solution, when it is necessary to dismantle the frame on the upper layer, the operator can wear gloves and then hold the handle, which is not easy to slip, saves time and effort, is highly efficient and safe.

[0026] In an optional embodiment, the frame further includes an annular enclosure, which is mounted on the first side surface, and the annular enclosure cooperates with the first side surface to form a groove.

[0027] Based on the above solution, the medicinal materials are located in the groove. When the two layers of the frame are flipped, the two layers of the frame clamp the medicinal materials and move together. The medicinal materials on the side are blocked by the annular enclosure and are not likely to fall from the edge of the grid body, which is not likely to cause waste.

[0028] The beneficial effects of the embodiments of the present invention include, for example:

[0029] In summary, the open drying box provided in this embodiment, when in use, spread the medicinal materials flat on the carrier, turn on the blower, and allow hot air to enter the bottom of the carrier from the input hole. The hot air has a tendency to flow upward, and the hot air passes through the medicinal materials as it flows upward, thereby drying the medicinal materials. In order to adjust the flow speed of the hot air, the exhaust hood is opened, and the exhaust hood generates negative pressure above the opening. Under the action of the negative pressure, the hot air can be accelerated to leave the opening, and new hot air can continuously enter the chamber to continuously dry the medicinal materials. During the drying process, the driving mechanism can be operated as needed to drive the carrier to rotate, and the carrier drives the medicinal materials to rotate together, so that the contact position of the medicinal materials and the carrier changes, and the bottom of the medicinal materials can also be directly exposed to contact with the hot air, thereby improving the drying efficiency.

DETAILED DESCRIPTION

[0038] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Generally, the components of the embodiments of the present invention described and shown in the drawings herein can be arranged and designed in various different configurations.

[0039] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but rather merely represents selected embodiments of the present invention. All other embodiments derived by persons of ordinary skill in the art based on the embodiments of the present invention without creative effort are also within the scope of protection of the present invention.

[0040] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, it does not need to be further defined or explained in subsequent drawings.

[0041] In the description of the present invention, it should be noted that if the terms "upper", "lower", "inside", "outside", etc. appear, the orientation or position relationship indicated is based on the orientation or position relationship shown in the accompanying drawings, or is the orientation or position relationship in which the invented product is usually placed when in use. It is only for the convenience of describing the present invention and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it cannot be understood as a limitation on the present invention.

[0042] In addition, the terms "first", "second", etc., if used, are merely used to distinguish and describe, and should not be understood as indicating or implying relative importance.

[0043] It should be noted that, in the absence of conflict, the features in the embodiments of the present invention can be combined with each other.

[0044] In the prior art, medicinal materials are laid on a grid and are in a static state, so that hot air cannot easily directly contact the bottom of the medicinal materials, resulting in low drying efficiency.

[0045] In view of this, the designer provides an open drying box, which can adjust the position of the medicinal materials relative to the carrier 200 as needed, so that different parts of the medicinal materials can be directly exposed to the hot air environment and in direct contact with the hot air, thereby improving the drying efficiency.

[0046] Please combine Figure 1-Figure 5 In this embodiment, the open drying oven includes an oven body 100, a carrier 200, a blower, an exhaust hood 400, and a drive mechanism 500. The oven body 100 is provided with an open chamber, the bottom of which is provided with an air supply hole 110; the blower is connected to the air supply hole 110; the carrier is mounted on the oven body 100 and located above the air supply hole 110; the exhaust hood 400 is mounted above the open chamber; and the drive mechanism 500 is mounted on the oven body 100 and connected to the carrier 200 to drive the carrier 200 to rotate.

[0047] As described above, the working process of the open drying box provided in this embodiment is as follows:

[0048] Spread the medicinal materials flat on the carrier 200, turn on the blower, and use the blower to let hot air enter the chamber from the input hole, and flow upward from the bottom of the carrier 200. Hot air has a tendency to flow upward toward the open position. When the hot air flows upward, it passes through the medicinal materials, thereby drying the medicinal materials. In order to adjust the flow speed of the hot air, the exhaust hood 400 is opened, and the exhaust hood 400 generates a negative pressure above the opening. Under the action of the negative pressure, the hot air can be accelerated to leave the opening, and new hot air can continuously enter the chamber to continuously dry the medicinal materials. During the drying process, the driving mechanism 500 can be operated as needed to drive the carrier 200 to rotate, and the carrier 200 drives the medicinal materials to rotate together, so that the contact position of the medicinal materials and the carrier 200 changes, and the bottom of the medicinal materials can also be directly exposed to contact with the hot air, thereby improving the drying efficiency.

[0049] The following embodiments illustrate the details of the open drying box of the present application by way of examples.

[0050] Please combine Figure 1 In this embodiment, the exhaust hood 400 optionally includes a hood body 410, an exhaust duct 420, and a retractor 430. The hood body 410 is mounted above the opening; the exhaust duct 420 and the retractor 430 are both connected to the hood body 410; the retractor 430 is mounted on the ceiling; the retractor 430 is used to drive the hood body 410 to rise and fall to adjust the distance between the hood body 410 and the opening.

[0051] With this design, the cover body 410 is positioned on the ceiling via the telescopic device 430. The telescopic device 430 can drive the cover body 410 up and down, adjusting the distance between the cover body 410 and the box body 100, and thus adjusting the distance between the cover body 410 and the medicinal materials on the carrier 200. This allows for adaptive adjustment of the air extraction speed and efficiency according to different scenarios, providing flexibility. Furthermore, the air extraction pipe 420 can be connected to a negative pressure pump, making connection quick and easy.

[0052] It should be understood that in order to improve the installation position of the cover body 410 and the stability during the adjustment process, four telescopic devices 430 are arranged above the cover body 410. When the four telescopic devices 430 work together, the cover body 410 is subjected to more balanced force, is not easy to tilt, and is safe and reliable to use.

[0053] Optionally, the retractor 430 includes a winch and a cable. The winch is fixed to the ceiling, one end of the cable is connected to the winch, and the other end of the cable is connected to the cover body 410. The winch is used to adjust the winding length of the cable to adjust the height of the cover body 410 relative to the box body 100.

[0054] It should be understood that when the height of the cover body 410 needs to be adjusted, the winch is started, the shaft of the winch rotates, and the cable is wrapped around the shaft, shortening the length of the cable between the shaft and the cover body 410, and the cover body 410 rises; similarly, when the shaft is reversed to unwrap the cable, the length of the cable between the shaft and the cover body 410 is increased, and the cover body 410 descends, making the operation flexible.

[0055] It should be noted that the turntable can also be driven to move by a motor installed on the ceiling, and the cable is connected to the turntable, which can also achieve the purpose of adjusting the height of the cover body 410 by adjusting the length of the cable.

[0056] Alternatively, in other embodiments, the winch or the motor is directly mounted on the bracket, and the bracket can be fixed to the ground.

[0057] Alternatively, in other embodiments, the telescoping device 430 is a hydraulic cylinder or a pneumatic cylinder.

[0058] Please combine Figure 1 In this embodiment, the bottom of the box body 100 is optionally provided with multiple air delivery holes 110. An air collection hood 120 is mounted on the bottom of the box body 100. This hood 120 is connected to all of the air delivery holes 110. A connector 130 is provided on the hood 120, which is connected to an air pump. The provision of multiple air delivery holes 110 allows more hot air to enter the bottom of the medicinal materials, resulting in a wider distribution area for the hot air. The hot air passes through the medicinal materials from multiple locations, drying them and improving drying efficiency.

[0059] In this embodiment, optionally, the supporting frame 200 includes two frames 210 arranged opposite to each other, and both frames 210 are connected to the driving mechanism 500. The driving mechanism 500 is used to simultaneously drive the two frames 210 to rotate relative to the box body 100; the frame 210 located on the upper layer of the two frames 210 is detachably matched with the driving mechanism 500.

[0060] It should be understood that the two racks 210 are arranged relative to each other, the rack 210 located at the bottom can carry medicinal materials, and the rack 210 located at the top can be removed when the medicinal materials are dried to prevent the upper rack 210 from blocking the top of the medicinal materials. When the medicinal materials need to be reversed, that is, when the bottom of the medicinal materials can directly contact the hot air, the upper rack 210 is installed on the drive mechanism 500 and is located above the lower rack 210. The two racks 210 cooperate to clamp the medicinal materials. Then, the drive mechanism 500 is started, and the drive mechanism 500 drives the two racks 210 to flip, so that the lower rack 210 flips to the top and the upper rack 210 flips to the bottom. Then, the rack 210 that has been rotated up and is located at the upper layer is removed, so that the bottom surface of the medicinal materials that was originally in contact with the lower rack 210 is exposed, so that it can directly contact the hot air, thereby improving the drying effect.

[0061] It should be noted that the structures of the two frames 210 can be set to be the same. In order to avoid repetition and redundancy, the specific structure of one frame 210 is taken as an example for description.

[0062] Please combine Figure 2-Figure 5 In this embodiment, optionally, the frame body 210 includes a truss body 211, a first connecting sleeve 212, and a second connecting sleeve 213. The first connecting sleeve 212 and the second connecting sleeve 213 are respectively installed on opposite sides of the truss body 211, and the first connecting sleeve 212 and the second connecting sleeve 213 can be welded and fixed to the truss body 211. The truss body 211 can be a rectangular plate with a plurality of mesh holes formed thereon. At the same time, the first connecting sleeve 212 and the second connecting sleeve 213 can both be semi-cylindrical rings, and the two are coaxially arranged. A first limiting column 214 is provided on the inner arc surface of the first connecting sleeve 212; a second limiting column 215 is provided on the inner arc surface of the second connecting sleeve 213.

[0063] Furthermore, first and second mounting grooves 140, 150, with notches facing upward, are provided on opposite side walls of the box body 100. The bottom walls of the first and second mounting grooves 140, 150 are both curved surfaces that can tightly fit with the first and second connecting sleeves 212, 213, thereby stabilizing the frame 210. Furthermore, the upward-facing notches of the first and second mounting grooves 140, 150 do not prevent the frame 210 from moving upward and out of the mounting grooves. The first connecting sleeve 212 and the second connecting sleeve 213 are rotatably installed in the first mounting groove 140 and the second mounting groove 150 respectively; the driving mechanism 500 includes a driver 510, a mounting shaft 520 and a driving shaft 530, and the driver 510 is fixed to the box body 100; two first limiting grooves 160 are provided on the mounting shaft 520, and the mounting shaft 520 is located between the two first connecting sleeves 212, and the two first limiting columns 214 are respectively inserted into the two first limiting grooves 160; two second limiting grooves 170 are provided on the driving shaft 530, and the driving shaft 530 is located between the two second connecting sleeves 213, and the two second limiting columns 215 are respectively inserted into the two second limiting grooves 170; the driving shaft 530 is fixed to the driver 510, and the driver 510 is used to drive the driving shaft 530 to rotate.

[0064] It should be understood that the structure of the frame 210 is simple. The first connecting sleeve 212 cooperates with the mounting shaft 520, and the second connecting sleeve 213 cooperates with the drive shaft 530. When the motor is started, the drive shaft 530 can transmit torque to the second connecting sleeve 213, thereby driving the two-layer frame 210 to rotate together. In addition, the first connecting sleeve 212 on the other side of the two frames 210 is combined with the mounting shaft 520, and the mounting shaft 520 plays a role in supporting and transmitting torque. The rotation of the two-layer frame 210 is smooth and reliable. In addition, when the frame 210 is in a horizontal state, the frame 210 located on the top can move directly upward, the first limiting column 214 and the first limiting groove 160 are disengaged, and the second limiting column 215 and the second limiting groove 170 are disengaged, so that the upper frame 210 can be directly removed, which is convenient to operate.

[0065] It should be understood that in order to facilitate the plug-in fit between the first limiting column 214 and the first limiting groove 160, and also to facilitate the plug-in fit between the second limiting column 215 and the second limiting groove 170, the ends of the first limiting column 214 and the second limiting column 215 can be chamfered.

[0066] Optionally, the driver 510 includes a motor, a driving gear and a driven gear. The motor is fixed on one side of the box body 100, the driving gear is fixed on the shaft of the motor, and the driven gear is fixed on the driving shaft 530. The driving gear is engaged with the driven gear. After the motor is started, the driving gear rotates, driving the driven gear to rotate, thereby driving the driving shaft 530 to rotate, which is convenient and flexible to operate.

[0067] In this embodiment, the rack body 211 optionally has a first side surface and a second side surface facing each other. The first side surface is used to contact the medicinal material, and the first connecting sleeve 212 and the second connecting sleeve 213 are both protruding from the second side surface. By arranging the first connecting sleeve 212 and the second connecting sleeve 213 on the second side surface, the distance between the first side surfaces of the two-layer rack body 210 can be reduced, thereby better clamping the medicinal material.

[0068] Optionally, the structures of the first connecting sleeve 212 and the second connecting sleeve 213 can be identical. In this embodiment, to avoid redundant description, the structure of the first connecting sleeve 212 is described in detail. The first connecting sleeve 212 includes a sealing plate and an arcuate plate. The sealing plate is fixed to the second side surface, the arcuate plate is fixed to the sealing plate, and the first limiting column 214 is fixed to the inner arcuate surface of the arcuate plate; the inner arcuate surface mates with the outer circumference of the mounting shaft. The sealing plate connects the arcuate plate to the truss body 211, and the contact area between the sealing plate and the truss body 211 is large, making the connection structure firm and reliable.

[0069] In this embodiment, the frame 210 optionally further includes a handle 220 fixed to the second side surface. The handle 220 may be four in number. Two operators, each holding two handles 220, cooperate to lift the frame 210 on the upper level, facilitating operation. When the upper frame 210 needs to be removed, the operator can wear gloves and then hold the handle 220, which is less prone to slipping, saving time and effort, and increasing efficiency and safety.

[0070] Please combine Figure 3 or Figure 4 In this embodiment, the frame 210 optionally further includes an annular enclosure 230 mounted on the first side surface. The annular enclosure 230 cooperates with the first side surface to form a groove. The medicinal materials are located in the groove. When the two-layer frame 210 is flipped, the two layers of the frame 210 move together, holding the medicinal materials. The medicinal materials on the side are blocked by the annular enclosure 230 and are unlikely to fall off the edge of the grid body 211, thereby reducing waste.

[0071] The open drying box provided in this embodiment can adjust the position of the medicinal materials as needed during the drying process so that the bottom of the medicinal materials can be directly exposed to contact with hot air, thereby improving the drying efficiency.

[0072] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any changes or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in the present invention should be included in the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be based on the scope of protection of the claims.
