Description

Technical Field

[0001] This utility model relates to the technical field of feed extrusion devices, specifically a feed extruder with a preheating structure. Background Technology

[0002] A feed extrusion device (also known as a feed extruder) is a mechanical device that alters the physical form and nutritional structure of feed through high-temperature and high-pressure processing. It is primarily used to improve the palatability, digestibility, and utilization rate of feed. Its core function is to induce an extrusion reaction in feed ingredients through mechanical extrusion and thermal energy, forming a porous and loose structure.

[0003] For example, in the prior art, publication number CN209995331U discloses a pig feed raw material extrusion system, including a pig feed extrusion machine base. A material cylinder is fixed to the right of a drive motor mounted on the upper surface of the pig feed extrusion machine base, and a spiral rod inside the material cylinder has stacked spiral blades fixed to its surface. A feeding cylinder is fixed to the right of a metal frame mounted above the pig feed extrusion machine base, and a first rotary motor and a second rotary motor are installed on both sides of the feeding cylinder. A first metal baffle passes through the first and second through holes on both sides of the feeding cylinder, and an electric heating wire is installed in a heating plate inside the material cylinder. This utility model solves the problems of lack of pretreatment structure and poor sealing during grading operations of the extrusion system by setting up a feeding cylinder, a first rotary motor, a second rotary motor, a cutting blade, a first metal baffle, a second opening, a metal concave groove, a second metal baffle, and a third through hole.

[0004] However, in the aforementioned prior art, the feed is heated by contacting the heating wire when it enters the material barrel. The heating wire cannot actively raise the internal temperature of the material barrel before the feed enters it, which results in a slow temperature rise when the feed first enters the material barrel. Utility Model Content

[0005] The purpose of this invention is to provide a feed extruder with a preheating structure to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a feed extruder with a preheating structure, comprising a base plate, a material horizontal barrel, a preheating component, and a cutting component. A first seat and a second seat are provided on the base plate. The material horizontal barrel is disposed within both the first and second seats. A first motor is disposed within the first seat. The preheating component is disposed within the material horizontal barrel and includes a preheating hole located on the inner wall of the material horizontal barrel. A circulating water tank is provided on the upper surface of the second seat. A water pump and multiple electric heating rods are disposed within the circulating water tank. A water outlet pipe is fixedly connected to the outlet end of the water pump. The other end of the water outlet pipe is connected to the upper opening of the preheating hole. A return water pipe is fixedly connected to the lower opening of the preheating hole. The other end of the return water pipe penetrates the side wall of the circulating water tank and is connected within the circulating water tank. Before the feed enters the material barrel, the circulating water pre-filled in the circulating water tank can be heated by multiple electric heating rods. The heated circulating water is then pumped by a water pump through the outlet pipe to the preheating hole, so that the heat of the heated circulating water can be introduced into the material barrel through the preheating hole, thereby preheating the material barrel and enabling the feed to heat up quickly as soon as it enters the material barrel, thus improving heating efficiency.

[0007] Preferably, the side wall of the first seat has a motor slot, and the first motor is fixedly installed in the motor slot. The output shaft of the first motor is fixedly connected to a screw conveyor rod at one end located inside the material barrel. The first motor can drive the screw conveyor rod to rotate, thereby controlling the conveying of feed inside the material barrel.

[0008] Preferably, the surface of the spiral conveyor rod is provided with heating wires, the cutting assembly includes a feeding box with a feeding hole on its upper surface, two cutting rollers inside the feeding box, two secondary motors fixedly mounted on the upper surface of the primary seat, the output shafts of the two secondary motors being fixedly connected to the two cutting rollers respectively, a discharge hole on the upper surface of the material horizontal drum, and a through hole matching the discharge hole on the lower surface of the feeding box. When the feed enters the feeding box through the feeding hole, the two secondary motors are activated, causing the two cutting rollers to rotate relative to each other and cut the feed. After the cut feed enters the material horizontal drum, it is rapidly heated by the heating wires.

[0009] Preferably, the lower inner wall of the feed box is a 30° inclined surface centered on the through hole. By setting the lower inner wall of the feed box as a 30° inclined surface centered on the through hole, the cut feed can be guided along its inclined surface to the through hole at the center, thereby entering the material barrel.

[0010] Preferably, both the outlet pipe and the return pipe are made of aluminum-plastic composite material. Aluminum-plastic composite material pipes have good thermal insulation properties, which can effectively reduce heat loss of circulating water in the outlet and return pipes.

[0011] Preferably, the upper surface of the circulating water tank is provided with a water inlet hole, and a sealing plug is installed inside the water inlet hole. By providing a water inlet hole and a sealing plug, when the circulating water in the circulating water tank is depleted to a certain extent, the sealing plug can be pulled out to inject new circulating water into the circulating water tank through the water inlet hole, so as to ensure the stability of heating by conducting heat through the circulating water.

[0012] Preferably, an external power supply is provided outside the base plate, and the heating wire, the first motor, the water pump, the two second motors, and the multiple electric heating rods are all electrically connected to the external power supply. By providing an external power supply, the heating wire, the first motor, the water pump, the two second motors, and the multiple electric heating rods can maintain normal operation under the power supply of the external power supply.

[0013] In summary, this application includes the following beneficial technical effects:

[0014] This invention, by setting up a material horizontal barrel and a preheating component, allows circulating water heated by multiple electric heating rods in the preheating component to be injected into the preheating hole through a water pump and an outlet pipe before the feed enters the material horizontal barrel. The heat from the hot water in the preheating hole can be transferred to the material horizontal barrel to preheat it, thereby achieving rapid heating of the feed as soon as it enters the material horizontal barrel and improving heating efficiency.

[0015] This invention, by setting up a return water pipe, allows the circulating water after heat conduction to enter the recovery pipe from the other end of the preheating hole, and then guide the circulating water back into the circulating water tank through the return water pipe, which can effectively reduce the water cost when using heating circulating water to conduct heat.

[0022] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments. Example

[0023] like Figures 1-5 As shown, the present invention proposes a feed extruder with a preheating structure, comprising a base plate 1, a material horizontal barrel 4, a preheating component, and a cutting component. A first seat 2 and a second seat 3 are provided on the base plate 1. The material horizontal barrel 4 is disposed within both the first seat 2 and the second seat 3. A first motor 5 is disposed within the first seat 2. The preheating component is disposed within the material horizontal barrel 4 and includes a preheating hole 7 located within the inner wall of the material horizontal barrel 4. A circulating water tank 8 is provided on the upper surface of the second seat 3. A water pump 9 and multiple electric heating rods 14 are disposed within the circulating water tank 8. A water outlet pipe 10 is fixedly connected to the outlet end of the water pump 9, and the other end of the water outlet pipe 10 is connected to the upper opening of the preheating hole 7. A return water pipe 11 is fixedly connected to the lower opening of the preheating hole 7, and the other end of the return water pipe 11 penetrates the side wall of the circulating water tank 8 and is connected within the circulating water tank 8.

[0024] The working principle of a feed extruder with a preheating structure based on Embodiment 1 is as follows: Before the feed enters the material drum 4, the circulating water pre-injected in the circulating water tank 8 can be heated by multiple electric heating rods 14. The heated circulating water is then transported by the suction pump 9 through the outlet pipe 10 to the preheating hole 7, so that the heat of the heated circulating water can be introduced into the material drum 4 from the preheating hole 7, thereby achieving preheating of the material drum 4 and realizing rapid heating of the feed immediately after entering the material drum 4, thus improving heating efficiency. Example

[0025] like Figures 1-5As shown, the feed extruder with a preheating structure proposed in this utility model, compared with Embodiment 1, further includes: a motor slot is provided on the side wall of the No. 1 seat 2, a No. 1 motor 5 is fixedly installed in the motor slot, and a spiral conveying rod 6 is fixedly connected to one end of the output shaft of the No. 1 motor 5 located inside the material horizontal barrel 4; an electric heating wire is provided on the surface of the spiral conveying rod 6; the cutting assembly includes a feeding box 12, a feeding hole is provided on the upper end face of the feeding box 12, two cutting rollers 15 are provided in the feeding box 12, and two No. 2 motors 13 are fixedly installed on the upper end face of the No. 1 seat 2. The output shaft of machine 13 is fixedly connected to two cutting rollers 15 respectively. The upper end face of the material horizontal barrel 4 is provided with a material drop hole 16, and the lower end face of the feed box 12 is provided with a through hole matching the material drop hole 16. The lower inner wall of the feed box 12 is a 30° inclined surface centered on the through hole. The water outlet pipe 10 and the water return pipe 11 are both aluminum-plastic composite pipes. The upper end face of the circulating water tank 8 is provided with a water inlet hole, and a sealing plug is installed in the water inlet hole. An external power supply is provided outside the base plate 1. The heating wire, motor 5, water pump 9, two motors 13, and multiple electric heating rods 14 are all electrically connected to the external power supply.

[0026] In this embodiment, as Figure 5 As shown, after the feed enters the feed box 12 through the feed inlet, two No. 2 motors 13 are started, and their output shafts drive the two cutting rollers 15 to rotate relative to each other, thereby cutting the feed. The cut feed flows along the inner wall of the 30° inclined surface at the bottom of the feed box 12, passing through the through hole and the discharge hole 16 in sequence, and falls into the material horizontal bucket 4. At this time, the No. 1 motor 5 controls the spiral conveyor rod 6 to rotate and drive the feed forward. At the same time, the heating wire also heats the feed. In order to reduce the heat loss of the heating circulating water before it enters the preheating hole 7 through the outlet pipe 10 and the return pipe 11, the outlet pipe 10 and the return pipe 11 are made of aluminum-plastic composite material. The aluminum-plastic composite material has good heat insulation performance and can effectively reduce the heat loss of the heating circulating water before it enters the preheating hole 7. The heat loss in the water pipe 10 and the return water pipe 11 improves the heat conduction effect in the preheating hole 7. When the circulating water in the circulating water tank 8 loses heat due to continuous circulation, the operator can pull out the sealing plug from the water inlet and inject the replenished circulating water into the circulating water tank 8 through the water inlet to ensure that the water volume in the circulating water tank 8 is sufficient, thereby ensuring the heat conduction effect of the circulating water on the material barrel 4. The external power supply set outside the base plate 1 is electrically connected to the heating wire, the first motor 5, the water pump 9, the two second motors 13 and the multiple electric heating rods 14, so that the heating wire, the first motor 5, the water pump 9, the two second motors 13 and the multiple electric heating rods 14 can be powered by the external power supply to ensure normal operation.

[0027] The above specific embodiments are merely several preferred embodiments of this utility model. Based on the technical solution of this utility model and the relevant teachings of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments.
