[0036] In the description of the present application, it should be pointed out that unless otherwise specified and limited, the terms "mounting", "connecting", "connecting" should be understood broadly, for example, it can be fixedly connected, or it can be detachably connected, or integrally connected; it can be directly connected, or indirectly connected through an intermediate medium; it can be the communication between two elements. For ordinary skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0037] The following will be described in detail with reference to the accompanying drawings Figures 1 to 5 Further illustrate the present application.

[0038] Example one

[0039] In order to solve the technical problems existing in the background art, the present application provides a direct-fired drum spreading and airing machine, which is mainly used for cooling of vinasse.

[0040] In the specific technical solution, refer to Figure 1The direct blowing type cylinder spreading and airing machine comprises a rack 1 as a main mounting and bearing component; a hollow rotatable stirring bin 2 and a power assembly 5 driving the stirring bin 2 to rotate are horizontally arranged on the rack 1 for facilitating the conveying and cooling of the vinasse; a feeding bin 3 connected with the rack 1 is movably connected to one side of the stirring bin 2, and a discharging bin 4 connected with the rack 1 is movably connected to the other side of the stirring bin 2 for facilitating the feeding and discharging of the material, a feeding hopper 301 is communicated with the top of the feeding bin 3, and a discharging port 401 is arranged at the bottom of the discharging bin 4; stirring vanes 201 arranged in a spiral shape are arranged on the inner wall of the stirring bin 2 for stirring and conveying the material in the stirring bin 2, and a cooling assembly 6 is arranged for cooling the material in the stirring bin 2.

[0041] The working principle of the direct blowing type cylinder spreading and airing machine is as follows: the distilled vinasse is poured into the feeding hopper 301 through the transfer equipment, the vinasse enters the stirring bin 2 through the feeding hopper 301, the power assembly 5 is started, the power assembly 5 drives the stirring bin 2 to rotate, the stirring vanes 201 arranged in the stirring bin 2 gradually convey the vinasse from the side of the stirring bin 2 close to the feeding bin 3 to the side of the stirring bin 2 close to the discharging bin 4 in the process of rotation of the stirring bin 2, and finally the vinasse falls out of the discharging port 401 into the hopper 10 below.

[0042] The above structure is the same as that of the cylinder spreading and airing machine in the background art, but the cooling method of the cylinder spreading and airing machine in the background art is mainly that the vinasse in the stirring bin first transfers heat to the cooling bin through the bin wall of the cooling bin, and then the cooling air is introduced into the cooling bin, and the cooling air carries away the heat in the cooling bin. Therefore, there are technical problems of low cooling efficiency and difficulty in cleaning the material due to the leakage of the material into the cooling bin. Therefore, in view of the above technical problems, the cooling assembly is further improved as follows in the embodiment:

[0043] Referring to Figure 1 and Figure 2 , the cooling assembly 6 comprises an air outlet 601 horizontally arranged on the side wall of the feeding bin 3 and communicated with the stirring bin 2, and an air inlet 602 horizontally arranged on the side wall of the discharging bin 4 and communicated with the stirring bin 2, a fan 603 is arranged in the air inlet 602, and the fan 603 is an axial flow fan.

[0044] Working principle of the cooling component: During the rotation of the mixing chamber 2, which is also the process of conveying the lees, the blower 603 is started. The blower 603 draws ambient temperature natural air into the mixing chamber 2 through the air inlet 602. The natural air entering the mixing chamber 2 exchanges heat with the high temperature lees. Since the mixing chamber 2 is a closed structure, the high temperature gas that has completed the heat exchange with the lees is discharged through the air outlet 601. In order to reduce the running resistance of the cooling air in the mixing chamber 2, the air outlet 601 and the air inlet 602 can be arranged concentrically, and it is best to set them in the middle of the feed chamber 3 and the discharge chamber 4.

[0045] As can be seen from the above structure and working principle, compared with the indirect cooling method of existing drum drying machines, this invention directly introduces cooling air into the mixing chamber, allowing the cooling air to directly contact the mash and cool it directly. Therefore, it is a direct-blowing method, which shortens the cooling time and improves cooling efficiency. It also avoids the problem of difficult cleaning due to material leakage. In the background technology, drum drying machines cool one batch of mash in 25-30 minutes, while the direct-blowing drum drying machine of this invention cools one batch of mash in 12-15 minutes, thus increasing the cooling efficiency by approximately 100%.

[0046] Among them, reference Figure 1 The specific configuration of the power assembly 5 is as follows: the power assembly 5 includes a geared motor 501 mounted on the frame 1, the output end of the geared motor 501 is connected to a gear 502, and the outer wall of the mixing chamber 2 is provided with a rack 503 that matches the gear 502, and the gear 502 and the rack 503 are meshed together.

[0047] Working principle of power component 5: Start the reduction motor 501, and the reduction motor 501 drives the gear 502 to rotate synchronously. Since the gear 502 is meshed with the rack 503, the rotation of the gear 502 will drive the mixing chamber 2 connected to the rack 503 to rotate.

[0048] To protect rack 503, refer to Figure 1 Therefore, in this embodiment, a dust cover 504 is also provided on the outside of the rack 503. A dust filter 606 is provided on the air inlet 602.

[0049] In order to make the rotation of the mixing chamber 2 more stable, this embodiment also includes an auxiliary rolling component 7.

[0050] Specifically, refer to Figure 2The auxiliary rolling assembly 7 comprises two guide rails 701 arranged on the outer wall of the stirring bin 2, and the frame 1 is provided with auxiliary wheels 702 matched with the guide rails 701, and the guide rails 701 are rolling connected with the auxiliary wheels 702. The auxiliary wheels can assist the stirring bin 2 to rotate, increase the stress points of the stirring bin 2, and make the stirring bin 2 rotate more stably.

[0051] Embodiment two

[0052] In fact, the working principle of the direct blowing type roller spreading and cooling machine is similar to that of the traditional cement stirring tank, and both are realized by rotating the stirring bin to achieve the required material, and the difference is that the cement stirring tank is used to complete the mixing of the material, and the roller spreading and cooling machine is used to realize the conveying and cooling of the material. Therefore, in the process of conveying the vinasse, the roller spreading and cooling machine is limited by the weight of the vinasse, and most of the vinasse will accumulate at the bottom of the stirring bin during the rotation of the stirring bin. The vinasse accumulated at the bottom of the stirring bin has a small contact area with the cooling air, so the heat dissipation and cooling efficiency of the vinasse will be reduced. Therefore, in order to solve the above technical problems, on the basis of embodiment one, the embodiment makes the following further improvements:

[0053] Specifically, referring to Figure 4 In this embodiment, a scraper 202 perpendicular to the inner wall of the stirring bin 2 is arranged on the stirring blade 201, the scraper 202 can scatter the material and accelerate the heat dissipation of the material, and the height of the scraper 202 can be flush with the top of the stirring blade 201 or lower than the height of the stirring blade.

[0054] The working principle of the scraper: during the rotation of the stirring bin 2, when the scraper 202 is located at the bottom of the stirring bin 2, with the rotation of the stirring bin 2, the scraper 202 rotates synchronously with the stirring bin 2, and the scraper 202 gradually rotates from the bottom of the stirring bin 2 to the top of the stirring bin 2. During this rotation process, the vinasse at the bottom of the stirring bin 2 will accumulate in the angle formed between the scraper 202 and the inner wall of the stirring bin 2. That is, the scraper 202 will scoop up the vinasse, thereby avoiding the accumulation of the vinasse at the bottom of the stirring bin 2. When the scraper 202 is located at the top of the stirring bin 2 and starts to move towards the bottom of the stirring bin 2, the scraper 202 at this time cannot hold the vinasse, and the vinasse will fall off the scraper 202. In the process of falling of the vinasse from the top of the stirring bin 2, the vinasse can fully contact with the cooling air, thereby increasing the contact area of the vinasse and the cooling air, and greatly improving the cooling efficiency; at the same time, the falling vinasse has a certain potential energy, which can play a role in dispersing the vinasse. Because the freshly distilled vinasse has a high water content, it may appear to be in a lumped and knotted state.

[0055] Embodiment three

[0056] Because the distiller's grains are fermented and distilled, the spent gas is generated during the spreading process, which will affect the workers in the environment. In view of the above technical problems, on the basis of embodiment one, the embodiment makes further improvements as follows:

[0057] Specifically, referring to Figure 5 , the embodiment seals the air pipe joint 604 on the air outlet 601, and the air pipe joint 604 is connected with the air outlet pipe 605, and the end of the air outlet pipe 605 is connected with the condenser 8.

[0058] Working principle: the high-temperature gas after heat exchange with the distiller's grains in the stirring bin 2 enters the air outlet pipe 605 through the air outlet 601, and then enters the condenser through the air outlet pipe 605, and finally is condensed into liquid through the condenser. In order to further realize the sealing of the stirring bin 2, a cover plate matched with the shape of the feeding hopper 301 can be covered on the feeding hopper 301 after the distiller's grains completely enter the stirring bin 2; or the cover plate can be hinged with the feeding hopper 301, and the feeding hopper 301 is opened and closed by turning. The condenser is a prior art device, and its structure and working principle will not be described here.

[0059] Through the above structure and working principle, it can be known that the direct-fired drum spreading machine adopts a fully closed mode, and the spent gas after heat exchange can be condensed into liquid for collection, so that the spent gas after heat exchange is prevented from leaking into the environment, and the air quality of the environment is ensured.

[0060] During the spreading process of the distiller's grains, according to different types of distiller's grains, some need to add koji or auxiliary materials to the distiller's grains. The koji is convenient for the subsequent fermentation of the distiller's grains in the cellar, and the auxiliary material can be chaff, which can loosen the distiller's grains and facilitate the subsequent distillation. However, the existing drum spreading machine cannot add koji and auxiliary materials in the stirring bin. In addition, the traditional brewing process also divides the addition of koji and auxiliary materials into different brewing processes, which cannot be completed in the same process. Therefore, in view of the above technical problems, on the basis of embodiment one, the embodiment also makes further improvements as follows: the embodiment also includes a feeding assembly for adding auxiliary materials to the stirring bin.

[0061] Specifically, referring to Figure 5 , the feeding assembly of the embodiment includes a horizontally arranged spiral conveyor 9, one end of the spiral conveyor 9 extends into the stirring bin 2, and the other end extends to the outside of the stirring bin 2 through the air pipe joint 604. The spiral conveyor 9 is a prior art device, and its structure and working principle will not be described here.

[0062] Working principle: in the process of spreading and airing of the distiller's grains, when the koji or auxiliary materials need to be added to the distiller's grains in the stirring bin 2, the koji or auxiliary materials are added to the screw conveyor through the feeding port of the screw conveyor 9, the koji or auxiliary materials fall into the distiller's grains in the stirring bin 2 through the discharging port of the screw conveyor 9, and the stirring bin 2 mixes and stirs them. The number of the screw conveyors 9 can be determined according to the site installation of the equipment, and one screw conveyor 9 can be directly used, or two screw conveyors 9 can be spliced.

[0063] Through the above structure and working principle, it can be known that the koji required for the fermentation of the distiller's grains and the auxiliary materials required for the distillation of the distiller's grains can be added in the stirring bin, that is, the koji adding process and the auxiliary material adding process can be simultaneously completed in the spreading and airing process, three processes are concentrated into one process, the efficiency is greatly improved, and the functionality of the equipment is improved.

[0064] Example four

[0065] The stirring blades of the prior art drum spreading and airing machine are welded with the stirring bin. In the actual spreading and airing process, the spreading and airing time required by different types of distiller's grains and different amounts of distiller's grains is different. There are two ways to control the spreading and airing time of the distiller's grains in the stirring bin, one is to control the rotating speed of the stirring bin, and the other is to replace stirring blades of different specifications. The spacing between the blades of the stirring blades of different specifications is different, which is equivalent to the length of the path of the distiller's grains on the stirring blades being different, so that the purpose of controlling the spreading and airing time of the distiller's grains is achieved. However, the stirring blades of the prior art drum spreading and airing machine are welded with the stirring bin, so the spacing between the adjacent blades of the stirring blades cannot be adjusted. Therefore, in view of the above technical problems, on the basis of example one, the following further improvements are made in this embodiment:

[0066] In this embodiment, the stirring blade 201 and the stirring bin 2 are designed to be detachably connected, the stirring blade 201 is provided with an ear plate (not shown in the figure), and the stirring blade 201 is connected with the stirring bin 2 through the ear plate and bolts (not shown in the figure).

[0067] Through the above structure and working principle, it can be known that the stirring blades of the utility model are connected with the stirring bin in a detachable manner, so that the replacement of stirring blades of different specifications is facilitated, and the maintenance and cleaning of the stirring blades are also facilitated.

[0068] The above specific embodiments have further illustrated the purpose, technical scheme and beneficial effects of the utility model, and it should be understood that the above are only specific embodiments of the utility model, and are not used to limit the protection scope of the utility model, and any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model should be included in the protection scope of the utility model.
