Description

Technical Field

[0001] This utility model relates to the field of feed processing technology, and in particular to a feed cooling device for improving cooling effect. Background Technology

[0002] The feed production process mainly includes raw material slag removal, raw material crushing, batching, mixing, high-temperature pelleting, cooling and packaging. High-temperature pelleting is a process of maturing and compressing the mixed materials into pellets of a certain size under high temperature conditions. High-temperature pelleting conditions are conducive to sterilization, thereby improving the quality and safety of feed.

[0003] Generally, pellets produced through high-temperature granulation have high temperature and humidity. Moist and hot pellets are prone to breakage, making them unsuitable for direct packaging and prone to spoilage during storage. Therefore, feed needs to be cooled. Utility model CN219841678U discloses a feed pellet cooler, including a cooler body, a blowing device, an air outlet chamber, and a support. The blowing device is fixedly connected to the right side of the cooler body, the air outlet chamber is fixedly connected to the left side, and the support is fixedly connected to the bottom of the cooler body. An isolation mesh plate is embedded on the left side of the cooler body, and a transmission mechanism is fixedly installed on the top of the cooler body. An anti-clogging plate is provided on the left side of the isolation mesh plate. The isolation mesh plate prevents smaller pellets from being blown into the air outlet chamber by the blowing device, thus avoiding waste. This solves the problem that while the airflow blown out after the fan starts separates dust from pellets, the airflow also blows out smaller pellets, causing them to be discharged through the air outlet chamber, resulting in waste. This design provides the advantage of isolation.

[0004] However, in the cooler described in the above application, the damp feed is prone to clumping during the feed cooling process, which affects the cooling effect. Therefore, a feed cooling device that improves the cooling effect is proposed to solve the above problem. Utility Model Content

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0029] like Figure 1-4 As shown, the present invention proposes a feed cooling device for improving cooling effect, including a cooling chamber 1, a discharge pipe 2 connected to the lower end of the cooling chamber 1, and a feed hopper 3 connected to the upper end of the cooling chamber 1.

[0030] The cooling chamber 1 is equipped with a cooling component 4 for cooling feed.

[0031] In this invention, the cooling component 4 inside the cooling chamber 1 can vibrate and break up the feed during the cooling process, as well as circulate and cool it.

[0032] In an optional embodiment, the cooling component 4 includes a guide cylinder 41 fixedly connected to the inner wall of the cooling chamber 1. The lower end of the guide cylinder 41 is conical, and a servo motor 44 is fixedly installed at its conical end. The guide cylinder 41 has several guide holes 45 located above its conical end. The output shaft of the servo motor 44 is fixedly connected to a rotating shaft 48 that passes through the guide cylinder 41 and extends into the feed hopper 3. A conveying paddle 47 located inside the guide cylinder 41 is fixedly connected to the rotating shaft 48. Several stirring rods 49 located inside the feed hopper 3 are fixedly connected to the rotating shaft 48. A guide plate 42 is slidably connected between the outer side of the guide cylinder 41 and the inner bottom wall of the cooling chamber 1. An elastic element is provided on the guide plate 42 to support its vibration on the cooling chamber 1. A guide disc 43 is slidably connected to the outer surface of the lower end of the guide cylinder 41.

[0033] It should be noted that a drive motor 46 is fixedly installed on one side of the cooling chamber 1. The output shaft of the drive motor 46 passes through and extends into the cooling chamber 1, and is fixedly connected to a cam 412 located between the guide plate 42 and the guide disk 43. After the start of the drive motor 46 drives the cam 412 to rotate, it can repeatedly abut and press the guide plate 42, causing the guide plate 42 to vibrate back and forth on the vertical and horizontal plane. After the raised guide disk 43 abuts the cam 412, it can also be repeatedly pressed and abutted by the rotating cam 412 to vibrate.

[0034] In this embodiment, the stirring rod 49 on the rotating shaft 48 can stir and disperse the feed during the feeding process, while the guide plate 42 outside the guide cylinder 41 can guide and convey the feed in a spiral shape and vibrate and disperse the feed during the conveying process to reduce the possibility of the feed clumping before and during cooling, thereby improving the cooling effect. The lifting guide plate 43, in conjunction with the guide hole 45, can guide the feed back into the guide cylinder 41 for circulating cooling, further improving the feed cooling effect.

[0035] Among them, the guide plate 42 is spirally distributed between the guide cylinder 41 and the inner wall of the cooling chamber 1. The guide plate 42 has several ventilation holes, which are spirally distributed. Through the spiral guide plate 42 and the several ventilation holes on the guide plate 42, the feed is guided in a spiral shape, and the feed can be continuously cooled by cold air blown on the guide plate 42.

[0036] In addition, the elastic element consists of a set of support rods 410 and a return spring 411. The set of support rods 410 penetrates the inner top wall of the cooling chamber 1 and is fixedly connected to the guide plate 42. The return spring 411 is fixedly connected between the upper end of the support rods 410 and the cooling chamber 1. The guide plate 42 is elastically supported by the set of support rods 410 and the return spring 411.

[0037] Secondly, the upper surface of the feed guide plate 43 is concave, and a round hole is provided in the middle of the center. The size of the round hole is adapted to the size of the outer surface of the feed guide cylinder 41, so that when the raised feed guide plate 43 is in contact with the feed guide cylinder 41, the feed can be guided back into the feed guide cylinder 41 through the feed guide hole 45. When the lowered feed guide plate 43 is separated from the feed guide cylinder 41, the feed can be guided to be discharged through the discharge pipe 2.

[0038] In an optional embodiment, the inner wall of the cooling chamber 1 is provided with a support mechanism for supporting the lifting guide plate 43; the support mechanism includes two electric push rods 419 hinged to the inner wall of the cooling chamber 1, the output end of the electric push rod 419 is hinged to a support ring 416, the upper surface of the support ring 416 is fixedly connected to a vertical rod 417 extending into the guide plate 43, and a connecting spring 418 is fixedly connected between the support ring 416 and the guide plate 43.

[0039] It should be noted that the lower surface of the guide plate 43 is provided with a groove for the vertical rod 417 to slide. The vertical rod 417 cooperates with the groove to provide sliding support for the guide plate 43.

[0040] In this embodiment, the guide plate 43 is elastically supported by the vertical rod 417 and the connecting spring 418 on the support ring 416, and the guide plate 43 can be driven to rise and fall together by the electric push rod 419 while the support ring 416 is driven to rise and fall.

[0041] In an optional embodiment, a feed cooling air supply component is provided between the feed guide plate 42 and the feed guide plate 43; the air supply component includes an air guide ring 414 fixedly connected to the feed guide cylinder 41 and located between the feed guide plate 42 and the feed guide plate 43. The upper and lower surfaces of the air guide ring 414 are provided with a plurality of air outlets 413. An air inlet pipe 415 with one end penetrating through the cooling chamber 1 is connected to the outer side of the air guide ring 414. The interior of the air guide ring 414 is hollow, and the hollow part of it is connected to the air outlets 413 and the air inlet pipe 415 respectively.

[0042] In this embodiment, cold air is delivered into the air guide ring 414 through the air inlet pipe 415 and then discharged through the air outlets 413 on the upper and lower sides of the air guide ring 414, thereby blowing cold air to cool the feed guided by the feed guide plate 42 and feed guide plate 43.

[0043] It should be noted that the air inlet pipe 415 is connected to the cold air outlet and delivers cold air to the hollow air guide ring 414.

[0044] 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, which is common knowledge in the field. Since this utility model is mainly used to protect mechanical structures, the control method and circuit connection and other technical means will not be described in detail here.

[0045] The working principle in the above embodiments is as follows:

[0046] After the servo motor 44 is started, it drives the rotating shaft 48 and the conveying paddle 47 and stirring rod 49 located on the rotating shaft 48 to rotate, and feed that needs to be cooled can be put into the feed hopper 3. During the process of the feed being introduced through the feed hopper 3, it can be pre-stirred and dispersed by the stirring rod 49 on the rotating shaft 48. After the feed falls into the guide cylinder 41 and is sent out by the conveying paddle 47, it can be guided to the spiral guide plate 42. At this time, the drive motor 46 is started and drives the cam 412 to rotate, which can repeatedly push the vibrating plate 42 to vibrate, so as to drive the guided feed to vibrate together. Then, the cold air required for cooling is delivered through the air inlet pipe 415 and discharged through the air outlet 413 on the air guide ring 414, which can be evenly blown onto the feed guided by the guide plate 42 for cooling.

[0047] After cooling, the feed falls into the guide plate 43 after being guided by the guide plate 42, and can then be discharged through the concave part of the guide plate 43 and the discharge pipe 2.

[0048] When the feed needs to be cooled again, the electric push rod 419 can be activated to push the support ring 416 to lift the guide plate 43 so that the guide plate 43 is in contact with the outer surface of the lower end of the guide cylinder 41. The feed guided by the guide plate 42 can then be guided through the guide hole 45 into the guide cylinder 41, where it is conveyed by the conveying paddle 47 to the top of the guide plate 42 for further vibration guidance and cooling. This allows the feed to be selectively cooled once or more. At the same time, after the guide plate 43 is in contact with the guide cylinder 41, it can be rotated and squeezed by the rotating cam 412, so that the guide plate 43 can vibrate together with the guide plate 42 on the support ring 416 and the vertical rod 417 to improve the guiding and dispersing effect of the feed.

[0049] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
