Description

Technical Field

[0001] The invention relates to the technical field of drying devices, and in particular to a drying device for feed production and preparation. Background Art

[0002] A common drying device for feed production and preparation is a hot air circulation dryer, which uses hot air heated by a heat source and then sent into a drying chamber, where the airflow makes full contact with the feed to evaporate moisture. The device is generally composed of a feeding system, a drying chamber, a fan, a heating device, a discharging system, etc. The heat source can usually be electricity, gas or steam. During the drying process, the moist feed raw materials are evenly distributed in the drying chamber. The hot air takes away the moisture when passing through the feed layer and is discharged through the air outlet. The drying temperature and wind speed can be adjusted according to different raw materials and needs, thereby ensuring that the quality and nutritional components of the feed are not destroyed. In this way, the drying device can effectively remove moisture from the feed, prevent mildew, extend the shelf life, and ensure the safety and nutritional value of the feed.

DETAILED DESCRIPTION

[0030] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0031] Embodiment 1, as Figure 1 , Figure 2 and Figure 3 As shown, a drying device for feed production and preparation comprises a drying cylinder 1, a material storage cylinder 2 is fixedly connected to the lower end of the drying cylinder 1, a discharge port 3 is opened in the middle of the left side of the outer surface of the material storage cylinder 2, a material blocking door 4 is rotatably connected to the inner surface of the discharge port 3, and a driving component 5 is fixedly installed on the upper end of the drying cylinder 1. Through the arranged driving component 5, a transmission component 6, a conveying component 7 and an impact component 8 can be driven simultaneously without affecting the normal feeding and transmission efficiency;

[0032] The outer surface of the driving component 5 is rotatably mounted with a transmission component 6, through which the feed can be preliminarily scattered while being heated and dried, and the feed can be continuously transmitted downward during the scattering process;

[0033] A conveying assembly 7 is fixedly installed on the front surface of the drying drum 1. The conveying assembly 7 can cooperate with the scraping assembly 9 to sweep the feed that is still in block form into the conveying assembly 7. Then the conveying assembly 7 conveys the agglomerated feed into the drying drum 1 again. In addition, if the conveyed feed is too heavy, the block feed can also be dispersed, thereby improving the efficiency of subsequent drying of the feed.

[0034] An impact assembly 8 is fixedly installed on the lower side of the inner surface of the drying cylinder 1. Through the impact assembly 8, when the feed falls downward, the impact force is used to hit the surface of the impact assembly 8 to break it up, thereby avoiding the situation where part of the feed is agglomerated and cannot be effectively dried when drying the feed;

[0035] A scraping component 9 is slidably installed on the outer surface of the impact component 8. The scraping component 9 cooperates with the transmission component 6 to scrape off the feed adhering to the surface of the impact component 8, thereby preventing the feed from trying to adhere to the surface of the impact component 8 and affecting subsequent normal processing.

[0036] Embodiment 2: Based on Embodiment 1, this embodiment aims to achieve the purpose that the driving component 5 drives the transmission component 6 while the transmission component 6 dries the feed.

[0037] For details, see Figure 1 , Figure 3 , Figure 4 , Figure 5 and Fig.10 The driving assembly 5 includes a fixed outer ring 51 fixedly connected to the upper end of the drying cylinder 1, four connecting plates 52 are fixedly connected to the inner surface of the fixed outer ring 51 in a circular array, and the ends of the four connecting plates 52 close to each other are commonly fixedly connected to a fixed inner ring 53, and the inner surface of the fixed inner ring 53 is fixedly connected to a mounting platform 54, a shell 55 is fixedly connected to the middle of the upper end of the mounting platform 54, and a motor 56 is fixedly connected to the top wall of the shell 55, and the output end of the motor 56 is fixedly connected to a bevel gear 1 57 through a coupling, and a driving rod 58 is fixedly connected to the lower end of the bevel gear 1 57, and the driving rod 58 passes through the mounting platform 54 and extends to the inner cavity of the drying cylinder 1, and three circular hole plates 59 distributed in a linear array are fixedly connected to the middle of the front side of the upper end of the mounting platform 54, and the inner surfaces of the three circular hole plates 59 are commonly connected to the connecting rod 50 for rotation, and the rear end of the connecting rod 50 is fixedly connected to a bevel gear 2 501, and the bevel gear 2 501 and the bevel gear 1 57 are meshed with each other.

[0038] Furthermore, the transmission component 6 includes a connecting tube 61 rotatably connected to the lower end of the mounting platform 54, three transmission plates 62 are fixedly connected to the outer surface of the connecting tube 61 in a ring array, and a plurality of impact blocks 63 are spirally fixedly connected to the upper and lower parts of the outer surfaces of the three transmission plates 62. The upper end of the connecting tube 61 is fixedly connected to the lower end of the driving rod 58, and a heating mechanism is provided inside the connecting tube 61.

[0039] Furthermore, the three transmission plates 62 are all arranged in a spiral shape, and the plurality of impact blocks 63 are all arranged in a soft rubber material.

[0040] As can be seen from the above, the two ends of the four connecting plates 52 are fixedly connected to the fixed outer ring 51 and the connecting plate 52 respectively, so four arc holes are formed between the four connecting plates 52 and the fixed outer ring 51 and the connecting plate 52, so that the feed to be processed can be added into the drying drum 1 through the four arc holes;

[0041] When the feed to be processed is added into the drying cylinder 1, the motor 56 can be started to drive the output end of the motor 56 to drive the bevel gear 57 fixedly connected thereto to rotate. When the bevel gear 57 rotates, since the driving rod 58 is fixedly connected thereto, and the driving rod 58 passes through the mounting platform 54 and extends to the inner cavity of the drying cylinder 1 and is fixedly connected to the upper end of the connecting cylinder 61, the connecting cylinder 61 also rotates accordingly. When the connecting cylinder 61 rotates, since three transmission plates 62 are fixedly connected to the surface in an annular array, and the three transmission plates 62 are sequentially distributed up and down, the inner surface of the drying cylinder 1 and the outer surface of the storage cylinder 2 are connected. Three spiral tracks are formed between them, so that the feed added into the inner cavity of the drying cylinder 1 can be spirally transmitted downwards. During the transmission process, the heating mechanism inside the connecting cylinder 61 can heat and dry the feed inside the spiral track. During the processing and drying process of the feed in the spiral track, since the upper and lower parts of the outer surfaces of the three transmission plates 62 are spirally arranged and fixedly connected with a plurality of impact blocks 63, the feed can impact the surfaces of the impact blocks 63 during the drying and transmission process in the spiral channel, and then be scattered by the protrusions of the impact blocks 63, and then be transmitted in the spiral pipeline to the surface of the impact component 8 for secondary processing;

[0042] And it can be known from the above that the plurality of impact blocks 63 are all made of soft rubber material, which has high elasticity and toughness. When the soft rubber contacts the feed, it can effectively absorb and disperse the impact force, instead of directly transmitting the impact force like hard materials. The elasticity of the soft rubber enables the feed to distribute stress more evenly when impacted, thereby reducing the rebound of the feed and increasing the crushing effect. The friction coefficient of the soft rubber surface is relatively high, and it can provide more friction when in contact with the feed. This higher friction helps to improve the crushing effect of the feed particles, especially in the process of grinding or shearing. The soft rubber material can provide better bonding and enhance the crushing efficiency. The soft rubber material can effectively reduce the direct impact of the impact force on the feed, avoid excessive rebound force, maintain the stability of the feed particles, thereby improving the uniformity and effect of the crushing. Unlike hard materials, hard materials directly impacting the feed will cause larger particles to fly or incompletely crush, and the crushing efficiency is low. Therefore, the elasticity, friction and shock absorption characteristics of the soft rubber material enable it to provide a more efficient and uniform crushing effect when crushing the feed.

[0043] At the same time, when the bevel gear 1 57 rotates, it can be seen from the above that the bevel gear 1 57 and the bevel gear 2 501 are meshed with each other, so the bevel gear 1 57 can drive the bevel gear 2 501 meshed with it to rotate, and then the bevel gear 2 501 drives the connecting rod 50 fixedly connected to it to rotate on the inner surfaces of the three circular hole plates 59.

[0044] The above-mentioned heating mechanism is composed of heat source equipment, heat exchanger and temperature control system, and its specific working principle is as follows:

[0045] The working principle of the heating mechanism is to heat the air by the heat generated by the heat source equipment, such as a combustion furnace or a steam boiler. The heated hot air enters the drying cylinder 1. In the drying cylinder 1, the hot air contacts the wet feed and evaporates the moisture in the feed. The temperature control system monitors the air temperature to ensure the stability of the heat output and prevent the temperature from being too high or too low, thereby ensuring the drying effect and nutritional components of the feed are not destroyed. In this way, the drying device can efficiently remove moisture and ensure the quality of the feed.

[0046] Therefore, the heating mechanism is a conventional setting in the prior art, and its specific installation method, circuit connection method and control method are all conventional designs, and this solution will not be elaborated in detail.

[0047] Embodiment 3: Based on embodiment 2, in order to achieve the purpose of further crushing the lumps remaining in the feed after preliminary drying and crushing by using the impact component 8 and the scraping component 9.

[0048] For details, see Figure 3 , Figure 6 , Figure 7 and Fig. 9 The impact assembly 8 includes a conical cylinder 81 fixedly connected to the lower edge of the inner surface of the drying cylinder 1, and a plurality of drop holes 82 are opened on the outer surface of the conical cylinder 81.

[0049] Furthermore, the scraping assembly 9 includes an eight-shaped plate 92 slidably connected to the outer surface of the conical cylinder 81, and a transmission column 91 is fixedly connected to the upper portion of the outer surface of the eight-shaped plate 92. The upper end of the transmission column 91 is fixedly connected to the lower end of the connecting cylinder 61, and the inner surface of the eight-shaped plate 92 is in contact with the outer surface of the conical cylinder 81.

[0050] After the feed is initially dried and dispersed in the above steps, some feed may still be in bulk. When the bulk feed falls onto the surface of the conical cylinder 81, the impact force of the fall will cause the bulk feed to hit the surface of the conical cylinder 81 and then be dispersed. The dispersed feed and the dried and loosened feed can fall from the plurality of drop holes 82 on the surface of the conical cylinder 81 into the inner cavity of the storage cylinder 2 for storage.

[0051] From the above, it can be known that the upper end of the transmission column 91 is fixedly connected to the lower end of the connecting tube 61. Therefore, when the connecting tube 61 rotates, the transmission column 91 fixedly connected thereto can be driven to rotate at the same time, and the lower end of the transmission column 91 is fixedly connected to the splayed plate 92, and the inner surface of the splayed plate 92 fits with the outer surface of the conical tube 81. Therefore, when the splayed plate 92 rotates with the center of the connecting tube 61 as the center point, the residue adhering to the surface of the conical tube 81 can be scraped off, thereby achieving further dispersion of the feed, and thus preventing the feed from agglomerating after drying.

[0052] Embodiment 4: Based on Embodiment 3, this embodiment aims to transfer the agglomerated feed into the drying drum 1 again for processing.

[0053] For details, see Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 8 ,and Fig. 9The conveying assembly 7 includes a conveying pipe 71 fixedly connected to the middle part of the front side of the outer surface of the drying cylinder 1, an auger 1 72 rotatably connected to the middle part of the bottom wall of the conveying pipe 71, an L-shaped pipe 73 fixedly connected to the upper end of the conveying pipe 71, a bevel gear 3 74 fixedly connected to the upper end of the auger 1 72, a bearing rod 75 fixedly connected to the rear side wall of the inner surface of the L-shaped pipe 73, a bevel gear 4 76 rotatably connected to the rear end of the bearing rod 75, an auger 2 77 fixedly connected to the rear end of the bevel gear 4 76, an auger 2 77 rotatably connected to the front side wall of the inner surface of the L-shaped pipe 73 at the rear end, an extension rod 78 rotatably connected to the middle part of the rear end of the L-shaped pipe 73, the front end of the extension rod 78 passes through the rear end of the L-shaped pipe 73 and is fixedly connected to the rear end of the auger 2 77, a feed port 79 is provided at the lower part of the front side of the inner surface of the drying cylinder 1, and the feed port 79 is communicated with the inner cavity of the conveying pipe 71.

[0054] Furthermore, the bevel gear three 74 and the bevel gear four 76 are meshed with each other, and the rear end of the extension rod 78 is fixedly connected to the front end of the connecting rod 50.

[0055] Furthermore, the opening of the lower end of the L-shaped tube 73 is located on the upper side of the fixed outer ring 51 .

[0056] From the above, it can be known that the rear end of the extension rod 78 is fixedly connected to the front end of the connecting rod 50, so when the connecting rod 50 rotates, the extension rod 78 can be driven to rotate, and when the extension rod 78 rotates, the auger 2 77 fixedly connected thereto can be driven to rotate, and when the auger 2 77 rotates, since the bevel gear 4 76 fixedly connected to its front end is meshed with the bevel gear 3 74, and the front end of the bevel gear 4 76 is rotationally connected to the rear end of the bearing rod 75, when the bevel gear 4 76 rotates, the bevel gear 3 74 meshed therewith can be driven to rotate, and then the bevel gear 3 74 drives the auger 1 72 fixedly connected at its lower end to rotate on the bottom wall of the conveying pipe 71;

[0057] As can be seen from the above, a feed port 79 is provided at the lower front portion of the inner surface of the drying cylinder 1, and the feed port 79 is communicated with the inner cavity of the conveying pipe 71. Therefore, during the rotation of the above-mentioned splayed plate 92, part of the crushed block feed can be transferred from the feed port 79 into the conveying pipe 71, and then the auger 1 72 in a rotating state can transfer the feed upward. When it is transferred to the uppermost side of the conveying pipe 71, as can be seen from the above, the opening of the lower end of the L-shaped tube 73 is located on the upper side of the fixed outer ring 51. Therefore, the auger 2 77 in a rotating state can transfer the feed into the drying cylinder 1 again, thereby achieving the purpose of secondary processing. The steps of the secondary processing are the same as those described above, so this scheme will not be described in detail.

[0058] Finally, the material blocking door 4 can be opened by rotating, and the processed feed stored in the material storage barrel 2 can be taken out from the discharge port 3.

[0059] Therefore, the conveying assembly 7 provided in this solution can prevent a large amount of feed from agglomerating during the production process, thereby affecting the subsequent feed products.

[0060] It should be noted that the specific installation method of the motor 56, the circuit connection method and the control method used in the present invention are all conventional designs and will not be elaborated in detail in the present invention.

[0061] The above shows and describes the basic principles and main features of the present invention and the advantages of the present invention. It should be understood by those skilled in the art that the present invention is not limited to the above embodiments. The above embodiments and descriptions are only for explaining the principles of the present invention. Without departing from the spirit and scope of the present invention, the present invention may have various changes and improvements, which fall within the scope of the present invention to be protected.
