Abstract
Description
Technical Field
[0001] This application belongs to the field of soy sauce production technology, and in particular relates to a filter cloth drying device. Background Technology
[0002] The production process of soy sauce generally includes fermentation, solid-liquid separation, heating, clarification, filtration, and packaging. The solid-liquid separation process typically uses a pressing method, which involves wrapping the soy mash in a square filter cloth and then pressing it with a press. The liquid is expelled, leaving dry residue inside the filter cloth. After cleaning the residue and the filter cloth, the filter cloth itself needs to be washed for future use.
[0003] As food safety and product variety requirements become more refined and sophisticated, the requirements for cleaning filter cloths are also increasing. However, no matter how much cleaning is done, it is impossible to completely remove some residues or impurities attached to the filter cloth. Furthermore, some bacteria are more likely to multiply in the humid environment of the filter cloth. Therefore, it is necessary to quickly dry the cleaned filter cloth at high temperature to prevent the growth of bacteria and ensure the quality of soy sauce products. Utility Model Content
[0004] To address the shortcomings of the prior art, this application provides a filter cloth drying device that can quickly dry filter cloth.
[0005] To achieve the above objectives, the present invention employs the following technology: A filter cloth drying device, comprising: The drying drum is vertical and has an opening at the top, with a heating tube vertically installed in the middle of its interior. A cover plate, horizontally positioned above the drying drum and movable vertically, is used to close or open the top opening of the drying drum; Multiple mating shafts are vertically inserted into the bottom of the drying drum and arranged in a circular array around its central axis. The mating shafts are rotated around their own axes. Support bars are horizontally arranged and the number is consistent with the mating shafts. The middle part of each support bar is connected to the upper end of the corresponding mating shaft. Guide rails are vertically provided at both ends of the support bars. The strip frame is square and vertically arranged, with its two sides slidingly fitted onto corresponding guide rails along the vertical direction; a rotating shaft is vertically connected to the top of the strip frame, which is coaxial with the corresponding mating shaft; the rotating shaft rotates around its own axis and is connected to the bottom of the cover plate; the strip frame rotates synchronously with the mating shaft. The mounting section, located on the strip frame, is used to support and fix the filter cloth; The first drive unit is located on the outside of the drying drum and is used to drive the cover plate to move. The second drive unit, located at the bottom of the drying drum, is used to drive each mating shaft to rotate synchronously around its own axis.
[0006] The beneficial effects of this utility model are as follows: By coordinating the shaft, support bars, and guide rails, and combining them with the strip frame and mounting part, the contact between the filter cloth surface and the hot air is made more uniform, which can effectively reduce local overheating or drying dead zones; at the same time, the rotation of the filter cloth can effectively enhance the contact efficiency between the hot air and the filter cloth, accelerate moisture evaporation, and shorten the drying time.

Detailed Implementation
[0013] To make the objectives, technical solutions and advantages of the present utility model clearer, the implementation methods of the present utility model will be described in detail below with reference to the accompanying drawings. However, the embodiments described in the present utility model are only some embodiments of the present utility model, and not all embodiments.
[0014] This application provides a filter cloth drying device, such as... Figures 1-5 As shown in the figure, it includes: drying drum 1, cover plate 2, multiple mating shafts 3, support bar 4, strip frame 5, mounting part 6, first drive part 7, second drive part 8, etc.
[0015] Among them, such as Figure 1 and Figure 2 As shown, the drying barrel 1 is cylindrical and vertically arranged, and is fixedly mounted on a horizontal base plate 9 by multiple support columns 12. The top of the drying barrel 1 is open, and a heating tube 11 is vertically arranged in the middle of its interior. like Figure 1 As shown, the cover plate 2 is horizontally positioned above the drying drum 1 and can be moved vertically to close or open the opening at the top of the drying drum 1. like Figures 1-3 As shown, in this embodiment, there are four mating shafts 3. Each mating shaft 3 is vertically inserted through the bottom of the drying barrel 1 and arranged in a circular array around the central axis of the drying barrel 1. Each mating shaft 3 is rotated around its own axis. like Figures 1-4 As shown, the support bars 4 are horizontally arranged and the number is the same as that of the mating shafts 3. The middle part of each support bar 4 is connected to the upper end of the corresponding mating shaft 3. The two ends of the support bar 4 are vertically provided with guide rails 41. The guide rails 41 are arranged in a grooved plate structure. The two guide rails 41 on each support bar 4 are arranged opposite each other. The guide rails 41 are provided with strip holes 42 arranged along their length direction on both sides.
[0016] like Figures 2-5 As shown, the strip frame 5 is square and vertically arranged, and its size is adapted to the filter cloth. The two sides of the strip frame 5 slide and fit on the corresponding guide rail 41 in the vertical direction. The two sides of the lower end of the side frame 5 of the strip frame 5 are provided with mating rods 52 facing away from each other, and move and fit into the corresponding strip hole 42 in the length direction of the guide rail 41 respectively. The top of each strip frame 5 is vertically connected to a rotating shaft 51 coaxially arranged with the corresponding mating shaft 3. The rotating shaft 51 rotates around its own axis and is connected to the bottom of the cover plate 2.
[0017] like Figures 2-4 As shown, the mounting part 6 is located on the strip frame 5 and is used to support and fix the filter cloth; the first driving part 7 is located on the outside of the drying barrel 1 and is used to drive the cover plate 2 to move; the second driving part 8 is located at the bottom of the drying barrel 1 and is used to drive each mating shaft 3 to rotate synchronously around its own axis.
[0018] When applying, such as Figures 1-4 As shown, two of the four support bars 4 that are opposite each other are always parallel to each other. Before drying the filter cloth, ensure that two adjacent support bars 4 are perpendicular to each other. The mating rod 52 abuts against the lower end of the strip hole 42. When installing the filter cloth, the first drive unit 7 drives the cover plate 2 to rise vertically and drives the strip frame 5 to rise. The two sides of the strip frame 5 slide along the guide rail 41, and the mating rod 52 rises along the strip hole 42 until the mating rod 52 abuts against the upper end of the strip hole 42. At this time, the first drive unit 7 drives the cover plate 2, and the strip frame 5 is brought out of the drying barrel 1 by the cover plate 2. The operator spreads the filter cloth through the mounting part 6 and fixes it on the strip frame 5. The filter cloth is set vertically, and its plane is parallel to the plane of the strip frame 5. Figures 1-4As shown, after the filter cloths are installed on all four strip frames 5, the first drive unit 7 drives the cover plate 2 to move down, bringing each strip frame 5 back into the drying barrel 1 until the cover plate 2 closes the opening of the drying barrel 1. The heating tube 11 then heats up and dries the four filter cloths around it. During the drying process, the second drive unit 8 drives each cooperating shaft 3 to rotate synchronously, causing the support bar 4 to rotate synchronously, thereby driving the filter cloths installed on the strip frames 5 to rotate. When rotating, the surface of the filter cloth contacts the hot air more evenly, which can effectively reduce local overheating or drying dead corners. At the same time, the rotation of the filter cloth can effectively enhance the contact efficiency between the hot air and the filter cloth, accelerate the evaporation of moisture, and shorten the drying time. After drying, the second drive unit 8 stops, and the first drive unit 7 lifts the cover plate 2 to remove the strip frames 5 from the drying barrel 1. Then, the dried filter cloths are removed. The dried filter cloths can effectively prevent the growth of miscellaneous bacteria and ensure the quality of the soy sauce.
[0019] By using the structure of the guide rail 41 and the cooperation between the strip hole 42 and the mating rod 52, it can be ensured that both sides of the strip frame 5 are stably fitted within the guide rail 41, avoiding motion interference when the strip frame 5 rises or falls. At the same time, it can realize the synchronous rotation of the strip frame 5 and the guide rail 41, improve the stability during rotation, and ensure the reliability of the drying equipment.
[0020] Specifically, such as Figures 1-4 As shown, the second drive unit 8 includes a motor 81 fixedly mounted on the bottom of the substrate 9 and a planetary gear mechanism 82 disposed between the substrate 9 and the bottom of the drying barrel 1. The drive end of the motor 81 is vertically mounted through the substrate 9 and is coaxially mounted with the central axis of the drying barrel 1. The planetary gear mechanism 82 includes a sun gear 83 coaxially mounted on the upper end of the drive end of the motor 81 and a gear ring 84 mounted on the substrate 9. The gear ring 84 is coaxially mounted with the sun gear 83 and rotates around its own axis. The upper end of the mating shaft 3 is mounted through the bottom of the drying barrel 3, and its lower end is rotatably connected to the substrate 9. Each mating shaft 3 is coaxially provided with planetary gears 85 that mesh between the gear ring 84 and the sun gear 83.
[0021] When applying, such as Figures 2-4 As shown, the lower end of the mating shaft 3 is rotatably connected to the base plate 9 and fixed relative to the planetary carrier. At this time, the planetary gear 84 can only rotate on its own axis, and a fixed-axis gear train is formed between the sun gear 83 and the gear ring 84. The motor 81 drives the sun gear 83 to rotate, and the sun gear 83 meshes with each planetary gear 85, causing each planetary gear 85 to rotate around its own axis. The planetary gear 85 drives the gear ring to rotate, thereby achieving the purpose of driving four mating shafts 3 to rotate synchronously with one motor 81, which can effectively reduce the production cost of the drying equipment. At the same time, the gear ring 84 can provide external support for the planetary gears 85, restricting the radial movement of the planetary gears 85, thereby maintaining the center distance between the sun gear 83 and the planetary gears 85, which can effectively avoid the problem of noise or wear caused by poor meshing between the sun gear 83 and the planetary gears 85.
[0022] Specifically, to facilitate the transfer and installation of the filter cloth, hanging loops are generally provided at the four corners of the filter cloth; such as Figures 2-4 As shown, the mounting part 6 includes two pairs of mounting posts 61 respectively located on both sides of the strip frame 5. The distance between the two mounting posts 61 in each pair is equal to the length of the filter cloth. The two mounting posts 61 on one side of the strip frame 5 are respectively arranged opposite to the two mounting posts 61 on the other side. Each end of the mounting post 61 is slidably fitted with a pull rod 62 along the width direction of the strip frame 5. The pull rod 62 has a barb 63 at its end. In application, the hanging rings at the four corners of the filter cloth are hung on the corresponding barbs 63, and then the pull rods 62 are separated in opposite directions to stretch the filter cloth and prevent wrinkles on the filter cloth from affecting the drying effect during drying.
[0023] Preferably, a spring can be installed in the hole through which the pull rod 62 passes in the mounting column 61. One end of the spring is connected to the bottom of the hole, and the other end is connected to the bottom of the pull rod 62. When the spring is in its natural state, the distance between the two barbs 63 is greater than the width of the filter cloth. By using the spring to stretch the filter cloth, the filter cloth is kept taut and stretched throughout the drying process, eliminating wrinkles in the filter cloth and further improving drying efficiency.
[0024] Preferred, such as Figure 3 As shown, four support blocks 91 are provided on the base plate 9 and arranged in a circular array around the axis of the drying barrel 1. Each support block 91 has an arc-shaped groove. A slip ring 92 is provided coaxially on the outer edge of the gear ring 84. The slip ring 92 slides around the axis 84 of the gear ring and is engaged in the arc-shaped groove. Through the cooperation of the slip ring 92 and the arc-shaped groove, the gear ring 84 can be supported to ensure the stability of the meshing between the gear ring 84 and the planetary gear 85.
[0025] Preferred, such as Figure 1 As shown, the first drive unit (7) can be in the form of a linear cylinder, hydraulic cylinder, etc.
[0026] The above description is only a preferred embodiment of this application and is not intended to limit this application. Obviously, those skilled in the art can make various modifications and variations to this application without departing from the spirit and scope of this application.
