Description

Technical Field

[0001] This invention relates to the field of brewing equipment technology, and more particularly to a fermentation device. Background Technology

[0002] After solid-state fermentation of baijiu, the mash in the fermentation pits needs to be removed from the pits. Currently, the methods for removing the mash in the fermentation pits include manual removal, gantry crane grab bucket removal, and chain plate removal. Among them, chain plate removal is more convenient than manual removal, saving a lot of labor costs. Moreover, chain plate removal is highly efficient and can be applied to layered removal processes.

[0003] However, when the chain conveyor is used for fermentation, the end in contact with the fermented mash uses the gripping structure on the chain to rub against the mash and achieve the gripping and transfer of the mash. This frictional material-carrying method usually cannot effectively transfer and transport the mash. In actual production, the mash is prone to falling during the upward conveying process, resulting in the accumulation of mash near the fermentation position. This accumulation of mash leads to incomplete fermentation and mixing between different layers of mash. How to achieve more complete discharge of mash from the fermentation pit and avoid mixing between different layers of mash has become one of the urgent technical problems to be solved. Summary of the Invention

[0004] In view of this, the present invention proposes a fermentation device, which aims to achieve complete discharge of the fermented mash in the fermentation pit by optimizing and improving the fermentation device.

[0005] The technical solution of the present invention is implemented as follows: The present invention provides a trough raising device, which includes: a fixed frame, a first plate chain conveyor and a second plate chain conveyor. The first plate chain conveyor and the second plate chain conveyor are both fixedly installed on the fixed frame. The first plate chain conveyor includes a first conveying surface that moves in a vertical direction, and the second plate chain conveyor includes a second conveying surface that moves in a vertical direction. The first conveying surface and the second conveying surface are arranged opposite each other and the conveying direction is upward. The first conveying surface and the second conveying surface are spaced apart.

[0006] In the above embodiments, both the first and second plate chain conveyors have unidirectional circulating conveyor chains. The lowermost part of the chain plate contacts the lees in the fermentation pit, and through friction, lifts and conveys the lees upwards, eventually leaving the pit. The first plate chain conveyor is used for outward conveying, and the second plate chain conveyor assists the first. Conventional lees removal devices typically include one plate chain conveyor. During the lees conveying process, the lowermost chain plate of this conveyor may cause the lees to fall from the edge, and this continuous accumulation can lead to… The accumulation of a large amount of lees on the side directly opposite the upward-moving chain plate affects the completeness of lees discharge. The above-described embodiment uses a second plate chain conveyor directly opposite the first plate chain conveyor, with the first and second conveying surfaces spaced apart to form a conveying channel. This allows the lees in this area to rise steadily without falling, and the lees accumulated on the side directly opposite the first plate chain conveyor will also be prevented from accumulating due to the chain plate circulation of the second plate chain conveyor, thus continuously being conveyed to the first plate chain conveyor for upward transport, overcoming the problem of lees falling and accumulating and being unable to be discharged.

[0007] In some embodiments, the first plate chain conveyor includes a first chain plate and a first gripping tooth disposed on the first chain plate, and the second plate chain conveyor includes a second chain plate and a second gripping tooth disposed on the second chain plate. The first gripping tooth and the second gripping tooth are staggered in the horizontal direction between the first chain plate at the location of the first conveying surface and the second chain plate at the location of the second conveying surface.

[0008] In the above embodiment, the first chain plates are connected end to end to form a closed loop. Through unidirectional cyclic rotation, continuous transport of the distiller's grains is achieved. The first conveying surface is a portion of the closed loop formed by the first chain plates. To achieve the lifting, upward conveying, and output of the distiller's grains, a downward-facing horizontal surface is provided at the upper end of the closed loop. When the distiller's grains are circulated to the downward-facing horizontal surface, they fall. A receiving structure is provided below the downward-facing horizontal surface to achieve the lifting and output of the distiller's grains. The first and second gripping teeth described above are both used to improve the gripping stability of the distiller's grains.

[0009] In some implementations, the conveying line speed of the first chain plate is greater than that of the second chain plate.

[0010] In the above embodiments, the first plate chain conveyor is used for conveying the lees. Therefore, it is necessary to ensure that the lees between the first conveying surface and the second conveying surface, as well as the lees located on the second conveying surface, are carried away by the first plate chain as much as possible. Therefore, the conveying linear speed of the first plate chain is set to be faster than that of the second plate chain. Moreover, the second gripping teeth and the first gripping teeth are staggered. When there are lees between the second gripping teeth, the first gripping teeth with the faster linear speed can scrape and drag these lees located between the second gripping teeth. The second plate chain conveyor is used to transfer the lees that fall from the first chain plate again, thereby achieving complete conveying of the lees and preventing them from accumulating on one side of the first plate chain and being unable to be transported out.

[0011] In some embodiments, the second plate chain conveyor further includes a third conveying surface, which is arranged horizontally downwards.

[0012] In the above embodiments, the second plate chain conveyor is mainly used to re-convey the lees dropped from the first plate chain conveyor back to the first plate chain conveyor for outward transport. Therefore, the location of the second plate chain conveyor occupies a certain space, which cannot be used for material transport by the first plate chain conveyor. Thus, the second plate chain conveyor is needed to transport the lees in this area to the first plate chain conveyor. Setting up a third conveying surface allows for horizontal transport of the lees in this area, placing them between the first and second conveying surfaces. Preferably, the third conveying surface is adjacent to and connected to the second conveying surface.

[0013] In some embodiments, a support frame is also included, wherein the fixing frame is slidably mounted on the support frame in a vertical direction.

[0014] In some embodiments, a lifting device is also included, which is fixed to the support frame and can reciprocate vertically on the support frame.

[0015] In some embodiments, a horizontal frame is also included, which is a horizontally positioned rectangular frame, and the support frame is slidably positioned above the horizontal frame.

[0016] In some embodiments, a first horizontal drive device is also included, which is fixed on the support frame and can drive the support frame to perform linear reciprocating motion along the long side of the horizontal frame.

[0017] In some embodiments, a support rail is also included, on which the horizontal frame slides along the length of the support rail, and the sliding direction of the horizontal frame is perpendicular to the sliding direction of the support frame.

[0018] In some embodiments, a second horizontal drive device is also included, which is fixed on the horizontal frame and can drive the horizontal frame to perform linear reciprocating motion on the support rail.

[0019] The present invention has the following advantages over the prior art:

[0020] This invention provides a more rationally designed fermentation device, which has a first plate chain conveyor for lifting materials for discharge, and a second plate chain conveyor for collecting and conveying the portion of fermented grains that is easy to fall and cannot be completely collected. By cooperating the first plate chain conveyor and the second plate chain conveyor, the fermented grains in the fermentation pit can be discharged more effectively, thus avoiding the problem that some fermented grains fall and accumulate during the discharge process and cannot be completely discharged.

[0032] like Figure 1 As shown, combined with Figure 2-4The present invention provides a trough raising device, which includes: a fixed frame 1, a first plate chain conveyor 2 and a second plate chain conveyor 3. The first plate chain conveyor 2 and the second plate chain conveyor 3 are both fixedly installed on the fixed frame 1. The first plate chain conveyor 2 includes a first conveying surface 21 that moves in a vertical direction, and the second plate chain conveyor 3 includes a second conveying surface 31 that moves in a vertical direction. The first conveying surface 21 and the second conveying surface 31 are arranged opposite each other and the conveying direction is upward. The first conveying surface 21 and the second conveying surface 31 are spaced apart.

[0033] In the above embodiment, the fixing frame 1 is used to fix the first plate chain conveyor 2 and the second plate chain conveyor 3 and maintain their relative positions. By moving the fixing frame 1, the positions of the first plate chain conveyor 2 and the second plate chain conveyor 3 can be changed simultaneously to achieve the removal of lees from different locations in the fermentation pit. Unlike the lees removal method of conventional plate chain lees removal equipment, the first plate chain conveyor 2 and the second plate chain conveyor 3 cooperate with each other. Specifically, the first plate chain conveyor 2 is used to transport the lees in the fermentation pit upwards and to the external receiving equipment. The second plate chain conveyor 3 is used to collect the lees that fall from the first conveying surface 21 of the first plate chain conveyor 2, and after circulating transportation, transport them back to the first conveying surface 21 of the first plate chain conveyor 2, and finally to the external receiving equipment. Compared with the conventional lees removal scheme of a single plate chain conveyor, this method can transport the target lees to the outside of the fermentation pit to the greatest extent possible, avoiding the problem of incomplete lees removal.

[0034] To further explain the working principle of the plate chain conveyor, we will now combine... Figure 2 The structure of the plate chain conveyor is described below. Specifically, the plate chain conveyor includes a drive structure, a chain, plate chains, and a frame. The first and last ends of the plate chain are connected to form a ring. The inner ring of the plate chain is attached and fixed with a chain. The frame is used to support the chain and the drive structure. The drive structure can drive the chain to rotate, thereby driving the plate chain to rotate. The surface of the plate chain has a conventional structure for scraping material, so that the plate chain can carry the lees when it comes into contact with them. The part of the ring-shaped plate chain near the lower end is used to contact the lees and scrape and carry the material. The plate chain is set downward at a suitable position to form a material dropping area. A corresponding material receiving structure is set below the material dropping area to achieve the purpose of transfer. In this embodiment, the upper end of the first plate chain conveyor 2 has a material dropping area on the side away from the first conveying surface 21, and the upper or lower end of the second plate chain conveyor 3 has a material dropping area on the side away from the second conveying surface 31.

[0035] In the above embodiments, the external receiving equipment can be a horizontally arranged plate chain conveyor or a temporary storage container for distiller's grains.

[0036] In some embodiments, the first plate chain conveyor 2 includes a first chain plate 22 and a first gripping tooth 23 disposed on the first chain plate 22, and the second plate chain conveyor 3 includes a second chain plate 32 and a second gripping tooth 33 disposed on the second chain plate 32. Between the first chain plate 22 at the location of the first conveying surface 21 and the second chain plate 32 at the location of the second conveying surface 31, the first gripping tooth 23 and the second gripping tooth 33 are staggered in the horizontal direction.

[0037] In the above embodiments, the first gripping tooth 23 and the second gripping tooth 33 are both used to grip and carry the lees. In order to avoid interference and collision between the first gripping tooth 23 and the second gripping tooth 33 between the first conveying surface 21 and the second conveying surface 22, the first gripping tooth 23 and the second gripping tooth 33 are staggered.

[0038] In some embodiments, the conveying line speed of the first chain plate 22 is greater than the conveying line speed of the second chain plate 32.

[0039] In the above embodiments, a clamping conveying channel is formed between the first conveying surface 21 and the second conveying surface 22, which can prevent materials from falling in this area to a certain extent. However, some clamped lees will still be attached to the second conveying surface 22. In order to avoid the accumulation of these lees on the second connecting plate 2, the first chain plate 22 feeds materials at a faster speed. At this time, the staggered first gripping teeth 23 can scrape and transfer the material on the second gripping teeth 33, realizing the process of transferring the lees from the second conveying surface 31 to the first conveying surface 21.

[0040] In some embodiments, the length of the first gripping tooth 23 is greater than the length of the second gripping tooth 33.

[0041] More preferably, the distance between the end of the first gripping tooth 23 and the surface of the second chain plate 32 between the first conveying surface 21 and the second conveying surface 22 does not exceed 2 mm.

[0042] In some embodiments, a flexible scraper is provided at the end of the first gripping tooth 23, and the flexible scraper is preferably made of silicone.

[0043] In some embodiments, the second plate chain conveyor 3 further includes a third conveying surface 34, which is arranged horizontally downwards.

[0044] In the above embodiments, another function of the second chain plate conveyor 3 is to scrape the area where the first chain plate conveyor is about to discharge material in advance. Specifically, the third conveying surface 34 scrapes the area where the lees are to be discharged. The scraped lees will be conveyed to the area below the second conveying surface 31 along with the third conveying surface, which helps to improve the efficiency and uniformity of lees discharge.

[0045] In some embodiments, a support frame 4 is also included, on which the fixing frame 1 can be slidably mounted in the vertical direction.

[0046] In the above embodiments, in order to achieve the removal of lees from different areas within the pit, it is necessary to drive the fixed frame 1 vertically. Therefore, a support frame 4 is used to provide a support structure for the fixed frame 1 to slide vertically. The support frame 4 is a cubic frame with a vertical channel in the middle. The fixed frame 1 and the first plate chain conveyor 2 and the second plate chain conveyor 3 located on the fixed frame 1 can all slide within this vertical channel.

[0047] In some embodiments, a lifting device 5 is also included, which is fixed on the support frame 4 and can reciprocate vertically on the fixed frame 1.

[0048] In the above embodiments, the lifting device 5 can adopt a conventional lifting structure, such as a winch or drive cylinder. In this application, a winch lifting structure with counterweights is used, specifically including two counterweights, a lifting chain, and a drive mechanism. The two ends of the chain are connected to the counterweights and the fixed frame 1, respectively. The middle of the chain is redirected via a guide wheel located at the top of the support frame 4. The drive mechanism can drive the chain to move in different directions, thereby achieving the raising and lowering of the fixed frame 1. Counterweights and chains are provided on opposite sides of the fixed frame 1, specifically as follows... Figure 1 As shown.

[0049] In some embodiments, a horizontal frame 6 is also included, which is a horizontally arranged rectangular frame, and the support frame 4 is slidably arranged above the horizontal frame 6.

[0050] In the above embodiments, in order to achieve slag removal processing at more different locations within the pit, a horizontal frame 6 is provided to support the support frame 4, allowing the support frame 4 to slide horizontally on the horizontal frame 6, thereby enabling slag removal in a horizontal direction. The support frame 4 has a rectangular frame structure, with a pair of parallel sides serving as slide rails, allowing the support frame 4 to slide on these slide rails.

[0051] In some embodiments, a first horizontal drive device 7 is also included. The first horizontal drive device 7 is fixed on the support frame 4 and can drive the support frame 4 to perform linear reciprocating motion along the long side of the horizontal frame 6.

[0052] In the above embodiments, the first horizontal drive device 7 is used to drive the support frame 4 to slide on the horizontal frame 6. Specifically, the first horizontal drive device 7 can adopt a common linear drive structure, such as an electric push rod, drive cylinder, belt drive, chain drive, roller drive, magnetic drive, linear motor, gear and rack system, etc.

[0053] In some embodiments, a support rail 8 is also included, and the horizontal frame 6 slides on the support rail 8 along its length direction, the sliding direction of the horizontal frame 6 being perpendicular to the sliding direction of the support frame 4.

[0054] In the above embodiments, to further improve the movable range of the fixed frame 1, a support rail 8 is provided, allowing the horizontal frame 6 to slide on the support rail 8. The length direction of the support rail 8 is perpendicular to the sliding direction of the support frame 4, enabling the fixed frame 1 to move in the horizontal plane and achieve slag removal processing in more areas. Moreover, this structure can be used for multiple pits simultaneously, for example, by arranging the support rails 8 of multiple pits side by side along their length directions, thus allowing the same slag removal device to be used for slag removal in multiple pits, saving equipment costs.

[0055] In some embodiments, a second horizontal drive device 9 is also included, which is fixed on the horizontal frame 6 and can drive the horizontal frame 6 to perform linear reciprocating motion on the support rail 8.

[0056] In the above embodiments, the second horizontal drive device 9 can adopt a common linear drive structure, such as an electric push rod, drive cylinder, belt drive, chain drive, roller drive, magnetic drive, linear motor, gear and rack system, etc.

[0057] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
