Description

Technical Field

[0001] The utility model relates to the technical field of feed cooling equipment, in particular to a feed processing cooling device. Background Art

[0002] Feed is a general term for food for all animals raised by humans. In a narrower sense, feed mainly refers to food for animals raised in agriculture or animal husbandry. Feed includes more than ten types of feed raw materials, such as soybeans, soybean meal, corn, fish meal, amino acids, miscellaneous meal, whey powder, oils, meat and bone meal, grains, feed additives, etc. After feed processing, it needs to be pelletized. The feed pellets obtained by pelletization are at a high temperature, so the feed needs to be cooled after pelletization.

[0003] The cooling of feed is carried out by a feed cooler. The operating principle of the feed cooler is mainly based on countercurrent cooling technology. The temperature of the feed is reduced by heat exchange between high-temperature feed and cooling medium (cooling water and cold air). The working process of the feed cooler can be roughly divided into the following steps: feeding, screening and falling, cooling medium entry, convection heat exchange and discharge.

[0004] However, in the prior art, countercurrent air cooling is used to cool the feed. The time the feed stays in the equipment is limited, and some of the feed falls too quickly, causing the feed to leave the equipment before being completely cooled. This results in insufficient cooling of the feed, requiring secondary or multiple cooling of the feed. Utility Model Content

[0005] The technical problem to be solved by the utility model is to cool the feed by countercurrent air cooling. The time the feed stays in the equipment is limited, and some of the feed falls too fast, resulting in the feed falling too fast leaving the equipment before being completely cooled, resulting in insufficient cooling of the feed, and the feed needs to be cooled twice or multiple times.

[0006] In order to solve the above technical problems, the technical solution of the utility model is:

[0007] A feed processing cooling device comprises a cooling box, a feed port is provided at the top of the cooling box, a feed frame is provided above the feed port and the feed frame is welded and fixed to the cooling box, a discharge port is provided at the bottom of the feed port, the interior of the cooling box is hollow and is provided with a first cooling guide plate and a second cooling guide plate, the first cooling guide plate and the second cooling guide plate are both S-shaped, the side surfaces of the first cooling guide plate and the second cooling guide plate are bent at ninety degrees, the side edges of the first cooling guide plate and the second cooling guide plate are affixed to each other and welded and sealed, and a plurality of equally spaced dividing plates are installed between the first cooling guide plate and the second cooling guide plate.

[0008] Preferably, a liquid drain pipe and a liquid inlet pipe are installed on one side of the cooling box, the position of the liquid inlet pipe is higher than the liquid drain pipe, and electromagnetic valves are provided inside the liquid drain pipe and the liquid inlet pipe.

[0009] Preferably, the material dividing plate includes two heat dissipation guide plates, which are fixed to the inner surface of the second cooling guide plate. A plurality of curved plates are provided between the two heat dissipation guide plates, and a diverter plate is fixed between the heat dissipation guide plate and the adjacent curved plates and between every two adjacent curved plates.

[0010] Preferably, a plurality of linearly distributed heat dissipation strips are fixed to the bottom of the diverter plate, and the bottom ends of the heat dissipation strips pass through the first cooling guide plate or the first cooling guide plate below the diverter plate and extend to the interior of the cooling box.

[0011] Preferably, the thermal conductivity of the heat dissipation strip is greater than the thermal conductivity of the diverter plate, and sealant is filled between the top end of the heat dissipation strip and the first cooling guide plate or the second cooling guide plate.

[0012] Compared with the prior art, the present invention has the following advantages:

[0013] 1. The first cooling guide plate, the second cooling guide plate and the separator plate are used to make the feed to be cooled roll down inside the cooling box. The S-shaped first cooling guide plate, the second cooling guide plate and the specially shaped separator plate extend the rolling time of the feed inside the cooling box, so that the coolant filled in the cooling box can fully absorb the heat of the feed, thus preventing the feed from leaving the cooling box too quickly, resulting in insufficient cooling of some feed and the need for re-cooling, thereby improving the cooling efficiency of the feed.

[0014] 2. Use heat dissipation strips to absorb the heat from the feed absorbed by the diverter plate. Since the heat dissipation strips are immersed in the coolant, the coolant directly cools the heat dissipation strips, accelerates the cooling of the feed, and avoids heat accumulation between the first cooling guide plate and the second cooling guide plate.

[0020] The following further describes specific embodiments of the present invention in conjunction with the accompanying drawings. It should be noted that the descriptions of these embodiments are intended to aid understanding of the present invention and do not constitute limitations on the present invention. Furthermore, the technical features involved in the various embodiments of the present invention described below may be combined with one another as long as they do not conflict with one another.

[0021] like Figure 1 As shown, a feed port 5 is provided at the top of the cooling box 1, a feed frame 4 is provided above the feed port 5 and the feed frame 4 is welded and fixed to the cooling box 1, a drain pipe 2 and a liquid inlet pipe 3 are installed on one side of the cooling box 1, the position of the liquid inlet pipe 3 is higher than the drain pipe 2, and solenoid valves are provided inside the drain pipe 2 and the liquid inlet pipe 3. Coolant is filled into the cooling box 1 through the liquid inlet pipe 3, and the heated coolant is discharged through the drain pipe 2 to realize the recycling of the coolant.

[0022] As the preferred technical solution of this embodiment, Figure 2 and Figure 3 As shown, a discharge port 6 is provided at the bottom of the feed port 5, the interior of the cooling box 1 is hollow and is equipped with a first cooling guide plate 7 and a second cooling guide plate 8, the first cooling guide plate 7 and the second cooling guide plate 8 are both S-shaped, the side surfaces of the first cooling guide plate 7 and the second cooling guide plate 8 are bent ninety degrees, the sides of the first cooling guide plate 7 and the second cooling guide plate 8 are fitted to each other and welded and sealed, a plurality of equally spaced dividing plates 9 are installed between the first cooling guide plate 7 and the second cooling guide plate 8, the first cooling guide plate 7, the second cooling guide plate 8 and the dividing plate 9 are utilized to allow the feed to be cooled to roll and fall inside the cooling box 1, and the S-shaped first cooling guide plate 7, the second cooling guide plate 8 and the specially shaped dividing plate 9 are utilized to extend the rolling time of the feed inside the cooling box 1, so that the coolant filled inside the cooling box 1 can fully absorb the heat of the feed.

[0023] As the preferred technical solution of this embodiment, Figure 4As shown, the dividing plate 9 includes two heat dissipation guide plates 93, which are fixed to the inner surface of the second cooling guide plate 8. A plurality of curved plates 92 are provided between the two heat dissipation guide plates 93. A diverter plate 91 is fixed between the heat dissipation guide plate 93 and the adjacent curved plates 92, and between every two adjacent curved plates 92. A wavy curved plate is formed by utilizing the diverter plate 91, the curved plate 92 and the heat dissipation guide plate 93, so that a wavy curved channel appears between adjacent dividing plates 9, thereby reducing the rolling speed of the feed between the first cooling guide plate 7 and the second cooling guide plate 8 and increasing the rolling time, so that the feed has enough time to be fully cooled.

[0024] A plurality of linearly distributed heat dissipating strips 10 are fixed to the bottom of the diverter plate 91. The bottom end of the heat dissipating strip 10 passes through the first cooling guide plate 7 or the first cooling guide plate 7 below the diverter plate 91 and extends to the inside of the cooling box 1. The thermal conductivity of the heat dissipating strip 10 is greater than the thermal conductivity of the diverter plate 91. Sealant is filled between the top of the heat dissipating strip 10 and the first cooling guide plate 7 or the second cooling guide plate 8. The heat dissipating strip 10 is used to absorb the heat from the feed absorbed by the diverter plate 91. Since the heat dissipating strip 10 is immersed in the coolant, the coolant directly cools the heat dissipating strip 10, accelerates the cooling of the feed, and avoids heat accumulation between the first cooling guide plate 7 and the second cooling guide plate 8.

[0025] Working principle: First, open the solenoid valve inside the liquid inlet pipe 3, and send the coolant into the cooling box 1 through the external water pump and water supply hose until the coolant slowly fills the cooling box 1 and completely immerses the first cooling guide plate 7 and the second cooling guide plate 8. Then close the solenoid valve inside the liquid inlet pipe 3 and stop the delivery of the coolant. Then, pour the feed to be cooled from the feed frame 4 into the feed port 5. The feed to be cooled directly enters the first cooling guide plate 7 and the second cooling guide plate 8 along the feed port 5, and rolls along the first cooling guide plate 7 and the second cooling guide plate 8 to the discharge port 6. When the feed to be cooled rolls between the first cooling guide plate 7 and the second cooling guide plate 8, because the first cooling guide plate 7 and the second cooling guide plate 8 Due to the presence of the dividing plates 9, the feed to be cooled will be dispersed and enter between the adjacent dividing plates 9. When the feed to be cooled rolls between the adjacent dividing plates 9, the heat contained in the feed to be cooled is absorbed by the first cooling guide plate 7, the second cooling guide plate 8 and the diverter plate 91. At this time, the coolant directly absorbs and cools the heat in the first cooling guide plate 7 and the second cooling guide plate 8. At the same time, the heat dissipation strips 10 absorb the heat absorbed by the diverter plate 91 and transfer it to the coolant, thereby increasing the retention time of the feed to be cooled inside the device, so that the internal heat of the feed to be cooled can be fully dissipated, avoiding the feed leaving the cooling box 1 too quickly, resulting in insufficient cooling of part of the feed and the need for re-cooling, thereby improving the cooling efficiency of the feed.

[0026] The embodiments of the present invention are described in detail above with reference to the accompanying drawings, but the present invention is not limited to the described embodiments. It is apparent to those skilled in the art that various changes, modifications, substitutions, and variations to these embodiments may be made without departing from the principles and spirit of the present invention, and these changes and modifications still fall within the scope of protection of the present invention.
