Description

Technical Field

[0001] This utility model relates to the field of feed pelleting equipment technology, and in particular to a feed circulating cooling pelleting device. Background Technology

[0002] Feed pelleting is the process of extruding powdered compound feed or single raw materials into pelleted feed using mechanical extrusion. The effects of temperature on feed pelleting are mainly reflected in the following aspects: 1. Under low temperature conditions (approximately 15℃ to 30℃): the feed moisture content is high, increasing the difficulty of pelleting and potentially leading to uneven particle size; 2. Under medium temperature conditions (30℃ to 70℃): the feed moisture content gradually decreases, improving the pelleting effect, and the compressibility, hardness, and particle size of the feed can all reach ideal levels; 3. Under high temperature conditions (above 80℃): the starch in the feed may denature and gelatinize, causing adhesion, increasing energy consumption costs, and potentially negatively impacting feed quality.

[0003] Most existing feed pelleting devices integrate raw material pretreatment, i.e., raw material crushing and pelleting equipment, to meet the needs of different customers. This integrated setup not only improves the applicability of the device but also greatly reduces the labor intensity of operators. However, in actual use, it has been found that the crushing shell in the raw material crushing mechanism will accumulate a lot of heat during long-term operation, which will cause the temperature of the raw material particles to rise, making them unsuitable for pelleting. They need to be cooled in the collection hopper for a period of time before pelleting, thus prolonging the entire pelleting time. Therefore, a feed circulating cooling pelleting device is proposed. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a feed circulating cooling pelleting device, which solves the technical problem of the inability to quickly dissipate heat when the temperature of the crushing shell rises during pelleting.

[0005] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a feed circulating cooling pelleting device, including a feed pellet mill, wherein the feed pellet mill includes a frame, a crushing mechanism and a pelleting mechanism disposed on the frame, and the frame is provided with a cooling mechanism for cooling the crushing shell in the crushing mechanism;

[0006] The cooling mechanism includes a cooling shell mounted on the crushing shell and a cooling tank mounted on the frame for supplying coolant to the cooling shell. The cooling shell and the cooling tank are connected to each other by two pipes.

Both ends of the heat dissipation pipe are connected to the flow direction control cavity. The heat dissipation pipe is provided with staggered heat dissipation fins for accelerating heat dissipation. The flow direction control cavity is equipped with a flow direction control plate. The partition plate has an inlet and an outlet for use with the flow direction control plate. The liquid storage cavity is connected to the flow direction control cavity through the inlet.

[0010] Preferably, the cooling assembly includes a drive motor mounted on the cooling tank, a drive shaft rotatably mounted inside the cooling tank, and a drive housing mounted inside the liquid storage chamber;

[0011] The output end of the drive motor is fixedly connected to one end of the drive shaft. The drive shaft has several blades fixedly installed inside the drive housing. The drive housing is provided with an inlet pipe and an outlet pipe. The inlet pipe is connected to the outlet on the partition plate. The drive shaft is also provided with a drive pulley.

[0012] Preferably, the agitation assembly includes a sealing ring disposed on the crushing shell and located on one side of the cooling shell, a drive ring rotatably disposed inside the sealing ring, a rotating ring rotatably disposed inside the cooling shell, and a plurality of fixed shafts disposed between the drive ring and the rotating ring, with scrapers disposed on the fixed shafts;

[0013] The agitation assembly also includes a driven shaft mounted on the frame. The driven shaft is equipped with a driven pulley and a driving gear. The driving pulley and the driven pulley are driven by a synchronous belt. The drive ring has an annular groove, and a ring of toothed blocks that cooperate with the driving gear are formed inside the annular groove.

[0014] Preferably, the cooling box is provided with a waterproof shell for use with the drive pulley.

[0018] This invention incorporates a cooling mechanism on the frame, utilizing the cooperation between the cooling shell and the cooling box to achieve rapid heat dissipation from the crushing shell. This ensures that the material in the crushing shell will not overheat during prolonged use, thus preventing any impact on the subsequent granulation quality.

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] Example 1

[0031] Please refer to Figures 1-8 A feed circulating cooling pelleting device includes a feed pellet mill 1. The feed pellet mill 1 includes a frame 101, a crushing mechanism and a pelleting mechanism disposed on the frame 101. The frame 101 is provided with a cooling mechanism 2 for cooling the crushing shell 102 in the crushing mechanism.

[0032] The cooling mechanism 2 includes a cooling shell 201 disposed on the crushing shell 102 and a cooling tank 202 disposed on the frame 101 for providing coolant to the cooling shell 201. The cooling shell 201 and the cooling tank 202 are connected to each other through two pipes.

[0033] The cooling shell 201 is equipped with an agitation component for stirring the coolant, and the cooling tank 202 is equipped with a cooling component 3 for driving the coolant to circulate.

[0034] As can be seen from the above, in order to reduce the heat accumulation of the crushing shell 102 in the crushing mechanism during long-term operation, a cooling shell 201 is provided on the crushing shell 102. The coolant in the cooling shell 201 carries away the heat accumulated on the crushing shell 102. In order to enable the cooling shell 201 to work continuously, the coolant needs to be circulated. Through the setting of the cooling box 202 and the cooling shell 201, the coolant circulates between the cooling box 202 and the cooling shell 201, thereby better cooling the crushing shell 102 and realizing cyclic cooling granulation. In order to prevent the coolant in the cooling shell 201 from flowing normally, an agitator is added to agitate the coolant. The cooling box 202 is equipped with a cooling component 3 to drive the coolant circulation. At the same time, the cooling component 3 can drive the agitator to work, making the cyclic cooling highly integrated and facilitating the transportation and installation of the entire granulation device.

[0035] Example 2

[0036] Please refer to Figures 2-5 This embodiment is basically the same as Embodiment 1. This embodiment is made on the basis of Embodiment 1 and has the same beneficial effects as Embodiment 1. The same parts can be referred to each other, and will not be described in detail here.

[0037] As a further technical solution of this embodiment, a partition plate 203 is provided in the cooling box 202, which divides the cooling box 202 into a liquid storage chamber and a flow control chamber from top to bottom.

[0038] The cooling tank 202 is equipped with several sets of heat dissipation components, including "W"-shaped heat dissipation pipes 204. Both ends of the heat dissipation pipes 204 are connected to the flow direction control chamber. Heat dissipation fins 205 for accelerating heat dissipation are staggered on the heat dissipation pipes 204. The flow direction control chamber is equipped with a flow direction control plate 206. The partition plate 203 is provided with an inlet and an outlet for use with the flow direction control plate 206. The liquid storage chamber is connected to the flow direction control chamber through the inlet.

[0039] Furthermore, the cooling assembly 3 includes a drive motor 301 mounted on the cooling tank 202, a drive shaft 302 rotatably mounted inside the cooling tank 202, and a drive housing 303 mounted inside the liquid storage chamber;

[0040] The output end of the drive motor 301 is fixedly connected to one end of the drive shaft 302. The drive shaft 302 has several blades 304 fixedly installed inside the drive housing 303. The drive housing 303 is provided with an inlet pipe 3031 and an outlet pipe 3032. The inlet pipe 3031 is connected to the outlet on the partition plate 203. The drive shaft 302 is also provided with a drive pulley 305.

[0041] As can be seen from the above, the working principle of the cooling component 3 in this utility model is as follows: the drive motor 301 works, which can drive the drive shaft 302 to rotate, thereby driving the drive pulley 305 and blades 304 set on it to rotate. Since several blades 304 are set in the drive housing 303, they can draw in coolant from the inlet pipe 3031 and discharge it from the outlet pipe 3032.

[0042] The liquid flow within the entire cooling tank 202 is as follows: coolant is manually added to the storage chamber, and the coolant in the storage chamber passes through the inlet on the partition plate 203 and enters the flow control chamber. Since the cooling tank 202 is equipped with several sets of heat dissipation components, the coolant passes through the W-shaped heat dissipation pipe 204 in sequence and is then discharged from the outlet on the partition plate 203. Furthermore, since the inlet pipe 3031 is connected to the outlet on the partition plate 203, the coolant will eventually enter the cooling shell 201 under the drive of the blades 304.

[0043] Example 3

[0044] Please refer to Figures 6-8 This embodiment is basically the same as Embodiment 1. This embodiment is made on the basis of Embodiment 1 and has the same beneficial effects as Embodiment 1. The same parts can be referred to each other, and will not be described in detail here.

[0045] As a further technical solution of this embodiment, the stirring component includes a sealing ring 208 disposed on the crushing shell 102 and located on one side of the cooling shell 201, a driving ring 209 rotatably disposed inside the sealing ring 208, a rotating ring 210 rotatably disposed inside the cooling shell 201, and a plurality of fixed shafts 211 disposed between the driving ring 209 and the rotating ring 210, with scrapers 2111 disposed on the fixed shafts 211.

[0046] The agitation assembly also includes a driven shaft 212 mounted on the frame 101. The driven shaft 212 is provided with a driven pulley 213 and a drive gear 214. The drive pulley 305 and the driven pulley 213 are driven by a synchronous belt. The drive ring 209 has an annular groove, and a ring of tooth blocks that cooperate with the drive gear 214 are provided in the annular groove.

[0047] As can be seen from the above, the agitation component can drive the coolant in the cooling shell 201 to flow in a certain direction. This arrangement can increase the contact area between the coolant and the crushing shell 102, thereby achieving a better cooling effect on the crushing shell 102. The specific working principle is as follows: after the drive pulley 305 rotates, it can drive the driven pulley 213 to rotate through the synchronous belt, which in turn drives the driven shaft 212 to rotate. The drive gear 214 is set on the driven shaft 212, so the rotation of the driven shaft 212 can drive the drive gear 214 to rotate, and the rotation of the drive gear 214 can in turn drive the driven gear 214 to rotate. The drive ring 209 is driven to rotate. Several fixed shafts 211 are provided between the drive ring 209 and the rotating ring 210. That is, the rotation of the drive gear 214 can drive the entire drive ring 209, rotating ring 210 and fixed shafts 211 to rotate. Since the fixed shafts 211 are provided with scrapers 2111, when the fixed shafts 211 rotate, the scrapers 2111 set at different angles can scrape the inner wall of the crushing shell 102 and the inner wall of the cooling shell 201, thereby improving the flow efficiency of the coolant and greatly improving the cooling effect of the coolant on the crushing shell 102.

[0048] Furthermore, the cooling tank 202 is equipped with a waterproof housing for use with the drive pulley 305. This design separates the timing belt and drive pulley 305 from the liquid storage chamber, thereby ensuring the normal operation of the drive pulley 305.

[0049] Furthermore, the liquid outlet pipe 3032 is interconnected with each other through a pipe on the cooling shell 201, and another pipe on the cooling shell 201 is interconnected with the bottom of the liquid storage chamber.

[0050] Furthermore, the length of the cooling shell 201 is less than the length of the crushing shell 102, and the cooling shell 201 needs to be located at the discharge port of the cooling shell 201, so that heat can be effectively dissipated from the heat accumulation area of ​​the crushing shell 102.

[0051] The control method of this utility model is automatic control through a controller. The control circuit of the controller can be implemented by simple programming by those skilled in the art. The power supply is also common knowledge in the field. Since this utility model is mainly used to protect mechanical devices, the control method and circuit connection will not be explained in detail.
