Description

Technical Field

[0001] The utility model belongs to the technical field of feed production, in particular to a low-temperature single-screw wet-pressed soft granular feed machine. Background Art

[0002] Low-temperature soft pellet feed is a special feed made by low-temperature pelleting process. Its main advantage is that the biological activity of microorganisms and additives in the feed can be maintained to a greater extent during the low-temperature manufacturing process.

[0003] In the existing low-temperature soft feed production process, it is usually manufactured by using a single-screw wet-pressed feed machine. The raw materials are transported and then extruded into shape by a screw. During long-term use observation, it was found that during the use of the existing single-screw wet-pressed feed machine, when the feed is extruded and transported by the screw, the rotation of the screw causes friction between the feed raw materials, resulting in an increase in the temperature of the feed, causing a decrease in internal biological activity and affecting the quality of the finished product.

[0004] To this end, the utility model provides a low-temperature single-screw wet-pressed soft pellet feed machine. Utility Model Content

[0007] Preferably, a plurality of thermal conductive plates are fixedly connected to the side wall of the refrigeration pipe; the plurality of thermal conductive plates are evenly distributed on the side wall of the refrigeration pipe; this step connects the refrigeration pipe with the thermal conductive plates, thereby increasing the temperature of the refrigeration pipe and the contact surface with the water in the reflux box, so that the temperature of the water flowing into the reflux box drops faster, thereby improving the cooling effect of the water.

[0008] Preferably, a collecting trough is fixedly connected to the top of the bottom plate; a collecting box is placed in the collecting trough; the collecting trough and the collecting box are slidably matched; in this step, by setting the collecting trough to connect the collecting box, the squeezed feed can be collected, reducing the situation of using additional containers for collection resulting in cumbersome operations, and at the same time, the extraction and return settings of the collecting box can improve the convenience of collecting the squeezed feed.

[0009] Preferably, a bellows is fixedly connected to the side wall of the water tank; a fan is fixedly connected to the top of the inner wall of the bellows; a plurality of ventilation holes are provided on the side wall of the bellows; in this step, by providing the bellows and the fan, the feed entering the collection box can be cooled by blowing air, so that the temperature of the feed in the collection box can be reduced faster, so as to reduce the situation where the high temperature remaining after the feed is squeezed out causes the ingredients to deteriorate.

[0010] Preferably, a filter is provided at the bottom of the bellows; the filter is detachably installed; in this step, the filter can be provided to filter the airflow blowing toward the collection box, thereby reducing the dust and impurities in the airflow from blowing onto the surface of the feed and causing contamination.

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] Specific examples are given below.

[0024] like Figures 1 to 4As shown, a low-temperature single-screw wet-pressed soft pellet feed machine described in an embodiment of the utility model comprises a bottom plate 1; a feed box 11 is fixedly connected to the top of the bottom plate 1; a feed bin 12 is connected to the top of the feed box 11; a discharge barrel 13 is connected to the side wall of the feed box 11; a water tank 14 is fixedly connected to the side wall of the discharge barrel 13; a water pump 15 is fixedly connected to the top of the bottom plate 1; a reflux box 16 is connected to the side wall of the water pump 15; the water pump 15 and the reflux box 16 are both connected to the water tank 14; a compressor 17 is fixedly connected to the top of the bottom plate 1; a refrigeration pipe 18 is fixedly connected to the top of the compressor 17; the refrigeration pipe 18 is located inside the reflux box 16; a water injection pipe 19 is connected to the top of the reflux box 16; when working, when the feed enters the discharge barrel 13 and is squeezed and transported by the screw, the water pump 15 is started to pump the water stored in the reflux box 16 The cold water is pumped out and then sent into the water tank 14. When the cold water enters the water tank 14, it will contact the discharge barrel 13, and the discharge barrel 13 can be cooled. At this time, the feed in the discharge barrel 13 can be cooled. The pumping action of the water pump 15 causes the water in the water tank 14 to re-enter the reflux box 16. At this time, the compressor 17 is started to refrigerate the refrigeration pipe 18, and the water entering the reflux box 16 can be refrigerated, and then the circulation is continued to cool the discharge barrel 13. In this step, the water pump 15 is set to connect the water tank 14 and the reflux box 16, and the compressor 17 and the refrigeration pipe 18 are matched, so that the cold water can be continuously circulated into the water tank 14 to cool the discharge barrel 13, so as to achieve the cooling treatment of the feed in the discharge barrel 13, and reduce the temperature increase caused by friction when the feed is squeezed and transported by the screw in the discharge barrel 13, which affects the deterioration of the feed components.

[0025] like Figure 2 As shown, a plurality of thermal conductive plates 2 are fixedly connected to the side wall of the refrigeration pipe 18; the plurality of thermal conductive plates 2 are evenly distributed on the side wall of the refrigeration pipe 18; during operation, when the compressor 17 drives the refrigeration pipe 18 to refrigerate, the thermal conductive plates 2 are evenly connected to the surface of the refrigeration pipe 18, and can conduct the temperature increase of the refrigeration pipe 18 to the contact surface of the water in the return box 16. In this step, by setting the thermal conductive plates 2 to connect the refrigeration pipe 18, the temperature increase of the refrigeration pipe 18 can be conducted to the contact surface of the water in the return box 16, so that the temperature of the water flowing into the return box 16 drops faster, thereby improving the cooling effect of the water.

[0026] like Figure 4As shown, a collecting groove 3 is fixedly connected to the top of the bottom plate 1; a collecting box 31 is placed in the collecting groove 3; the collecting groove 3 and the collecting box 31 are in sliding cooperation; during operation, when the feed is squeezed out from the end of the discharge barrel 13, it will fall into the collecting box 31 below, and the collecting box 31 will collect the falling feed. When the collection is completed, the collecting box 31 will be taken out from the collecting groove 3, and the collected feed will be poured out and then reset. In this step, the collecting groove 3 is connected to the collecting box 31 to collect the squeezed feed, thereby reducing the cumbersome operation caused by taking additional containers for collection. At the same time, the extraction and return setting of the collecting box 31 can improve the convenience of collecting the squeezed feed.

[0027] like Figure 3 As shown, the side wall of the water tank 14 is fixedly connected to a bellows 4; the top of the inner wall of the bellows 4 is fixedly connected to a fan 41; the side wall of the bellows 4 is provided with a plurality of ventilation holes 42; when working, the fan 41 is started to blow air into the collecting box 31 below, and when the feed is squeezed out of the discharge barrel 13 and enters the collecting box 31, the wind blown out by the fan 41 can cool the feed entering the collecting box 31 by blowing air. In this step, by setting the bellows 4 and the fan 41, the feed entering the collecting box 31 can be cooled by blowing air, so that the temperature of the feed in the collecting box 31 can be reduced faster, so as to reduce the situation where the high temperature remaining after the feed is squeezed out causes the deterioration of the ingredients.

[0028] like Figure 3 As shown, a filter screen 5 is provided at the bottom of the bellows 4; the filter screen 5 is detachably installed; during operation, when the airflow blows from the bellows 4 into the collecting box 31, the airflow will be filtered through the filter screen 5 at this time to filter out dust and impurities in the airflow. In this step, the airflow blowing toward the collecting box 31 can be filtered by setting the filter screen 5, thereby reducing the situation where dust and impurities in the airflow are blown onto the surface of the feed to cause pollution. At the same time, the filter screen 5 can reduce the slag generated when the feed is squeezed out of the discharge barrel 13 from entering the ventilation hole 42 to cause blockage.

[0029] like Figure 1 As shown, a cover plate 6 is hinged on the top of the feed bin 12; a handle 61 is fixedly connected to the top of the cover plate 6; during operation, when the feed raw materials are added from the feed bin 12, the handle 61 can be held to rotate the cover plate 6 to open and then add the raw materials. After adding, the cover plate 6 is rotated to cover the top of the feed bin 12. This step is achieved by arranging the cover plate 6 and the handle 61, which are opened when adding and closed after adding, so as to reduce the situation in which the powder generated when the raw materials are transported in the feed box 11 and the feed bin 12 is rebounded from the feed bin 12 and scattered around.

[0030] like Figure 4As shown, the discharge barrel 13 and the side wall of the water tank 14 are fixedly connected with a sealing ring 7; when working, the sealing ring 7 is located at the connection between the water tank 14 and the discharge barrel 13, and the discharge barrel 13 and the water tank 14 can be sealed. In this step, the connection between the discharge barrel 13 and the water tank 14 can be sealed by setting the sealing ring 7, thereby reducing the situation where water in the water tank 14 overflows from the connection.

[0031] Working principle: when the feed enters the discharge barrel 13 and is squeezed and transported by the screw, the water pump 15 is started to extract the cold water stored in the reflux box 16 and then send it into the water tank 14. When the cold water enters the water tank 14, it will contact the discharge barrel 13, and the discharge barrel 13 can be cooled. At this time, the feed in the discharge barrel 13 can be cooled. The pumping action of the water pump 15 causes the water in the water tank 14 to re-enter the reflux box 16. At this time, the compressor 17 is started to refrigerate the refrigeration pipe 18, which can refrigerate the water entering the reflux box 16, and then continue to circulate to cool the discharge barrel 13. When the compressor 17 drives the refrigeration pipe 18 to refrigerate, the temperature conducting plate 2 is evenly connected to the surface of the refrigeration pipe 18, which can conduct the temperature increase of the refrigeration pipe 18 to the contact surface with the water in the reflux box 16. When the feed is squeezed out from the end of the discharge barrel 13, it will fall to the collection tank below. The collecting box 31 is in the collecting box 31. At this time, the collecting box 31 collects the fallen feed. When the collection is completed, the collecting box 31 is taken out from the collecting trough 3. After the collected feed is poured out, the collecting box 31 is reset. The fan 41 can be started to blow air into the collecting box 31 below. When the feed is squeezed out of the discharge barrel 13 and enters the collecting box 31, the wind blown by the fan 41 can blow and cool the feed entering the collecting box 31. When the air flow blows from the bellows 4 into the collecting box 31, it will pass through the filter 5 to filter the air flow and filter out dust and impurities in the air flow. When the feed raw materials are added from the feed bin 12, the handle 61 can be held to rotate the cover 6 to open it and then add the raw materials. After adding, the cover 6 is rotated to cover the top of the feed bin 12. The sealing ring 7 is located at the connection between the water tank 14 and the discharge barrel 13, and the discharge barrel 13 and the water tank 14 can be sealed.
