Description

Technical Field

[0001] The utility model relates to the technical field of puffing, in particular to a puffing device for feed production. Background Art

[0002] Feed is a general term for food for 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 soybean, soybean meal, corn, fish meal, amino acids, miscellaneous meal, whey powder, oil, meat and bone meal, grains, feed additives, etc. When producing synthetic feed, in order to improve the utilization rate of nutrients in the feed, it is necessary to expand the feed. The extruder converts mechanical energy into thermal energy and uses the heat generated by the rotation of the machine to squeeze the feed. The most obvious feature of the expanded feed is that its volume becomes larger.

[0003] At present, in the process of puffing, the piled feed is easy to get damp and clump, and the agglomerated feed is easily added to the puffing machine, which will cause equipment blockage. In addition, the amount and speed of feed entering the puffing machine are difficult to control. If too much feed is fed in a short period of time, the inside of the puffing machine will also be blocked, resulting in no feed coming out of the puffing machine outlet. Therefore, it is necessary to provide a puffing device for feed production. Utility Model Content

DETAILED DESCRIPTION

[0019] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention. Example

[0020] A puffing device for feed production, such as Figures 1 to 3 As shown, it includes a box body 1, a feed hopper 3 is connected to the top of the box body 1, an expander 4 is connected to the bottom of the box body 1, and a support frame 2 is provided between the expander 4 and the bottom of the box body 1. The expander 4 is fixed on the base 6 through a support column, and a collection box 7 corresponding to the discharge port 5 is provided on one side of the base 6. A jacket is provided on the periphery of the expander 4, and a heating medium is introduced into the jacket. A spiral shaft is provided in the expander for rotation, and a spiral blade is provided on the spiral shaft. The squeeze between the spiral blade and the inner wall of the cavity causes the feed to be heated and expanded, and the expanded feed falls from the discharge port into the collection box.

[0021] A stirring chamber 11, a filtering chamber 12, and a feeding chamber 13 are sequentially arranged in the box body 1 from top to bottom. Two guide plates 113 with inclined upper ends are arranged between the stirring chamber 11 and the filtering chamber 12. The filtering box 125 is located at the discharge channel surrounded by the two guide plates 113. The outlet of the feeding chamber 13 is connected to the feed port of the extruder 4. A discharge port 5 is arranged at the other end of the extruder 4.

[0022] A plurality of heating plates 110 are provided on the inner wall of the mixing chamber 11. A mixing mechanism is provided in the mixing chamber 11, and the mixing mechanism includes two mixing rollers 112 and a plurality of mixing rods 111 distributed in an annular array on the outer wall of the mixing rollers 112. The mixing rollers 112 are arranged on the inner wall of the box body 1 and rotated by roller shafts 114. The output shaft of the mixing motor 115 can be coaxially arranged with the roller shaft 114 to drive the mixing roller 112 to rotate, or the mixing motor 115 can be connected to only one of the roller shafts by a transmission wheel and a belt transmission connection. The mixing rods 111 break up the agglomerated feed in the mixing chamber 11, and heat and dry the damp feed through the heating plates 110.

[0023] A filter box 125 is provided in the filter chamber 12, a material discharge channel 130 is provided between the filter chamber 12 and the material discharge chamber 13, and a material discharge control mechanism is provided in the material discharge chamber 13. The material discharge control mechanism includes a rotating shaft 135 rotatably provided in the material discharge chamber 13, a fixed sleeve 132 fixed on the rotating shaft 135, and a plurality of connecting rods 134 distributed in an annular array on the outer wall of the fixed sleeve 132. A baffle 131 is connected to the other end of the connecting rod 134. A driving motor 133 is provided on the outer wall of the box body 1, and the output shaft of the driving motor 133 is coaxially connected to the rotating shaft 135. The baffle 131 cooperates with the outlet blockage of the material discharge channel 130. The outlet of the material discharge channel 130 is an arc-shaped setting, and the outer wall of the baffle 131 is an arc surface that cooperates therewith. The arc-shaped baffle 131 cooperates with the arc-shaped outlet of the material discharge channel 130, and the blocking effect is better.

[0024] A shaking mechanism is provided on the filter box 125, and the shaking mechanism includes a moving rod 122 connected to the upper ends of both sides of the filter box 125, a rack 123 provided at the lower end of one side of the filter box 125, and a gear 126 meshing with the rack 123. The teeth on the gear 126 are arranged in a semi-ring. A fixing plate 124 is provided on the outer wall of the box body 1, and a U-shaped plate 127 is provided on the fixing plate 124. A gear 126 shaft is rotatably provided in the U-shaped plate 127, and the gear 126 is arranged on the gear 126 shaft. A shaking motor 129 is provided on one side of the U-shaped plate 127, and the output shaft of the shaking motor 129 is coaxially connected with the gear 126 shaft. The moving rod 122 and the rack 123 are respectively movably extended out of the box body 1 and connected to the limiting block 120. Compression springs 121 are respectively provided between the limiting block 120 and the outer wall of the box body 1 and between the filter box 125 and the inner wall of the box body 1. The shaking motor 129 drives the gear 126 to rotate. During the rotation of the gear 126, the rack 123 is driven to move, thereby driving the filter box 125 to move. At this time, the moving rod 122 moves to one side, and the compression spring 121 is in a compressed state. When the gear 126 rotates to a position without teeth, the compression spring 121 rebounds, causing the filter box 125 to shake, thereby improving the impurity filtering effect and preventing the mesh on the filter box 125 from being blocked.

[0025] When the utility model is working, firstly, feed is added into the mixing chamber 11 through the feed hopper 3, then the mixing rod 111 is used to mix and break the feed, and the heating plate 110 is used to heat and dry the feed inside the mixing chamber 111. In the mixing process, the feed can be heated evenly, and then the feed enters the filter box 125 through the guide plate to remove impurities inside the feed, so as not to affect the quality of the feed after expansion. During filtering, with the cooperation of the gear 126, the rack 123 and the compression spring 121, the filter box 125 is shaken left and right for filtering, and the filtered feed is discharged through the discharge channel 130. At this time, the driving motor 133 drives the rotating shaft 135 and the fixed sleeve 132 to rotate, thereby driving the arc-shaped baffle 131 connected to the connecting rod 134 to rotate, so that the outlet of the discharge channel 130 is intermittently blocked, so that the feed is intermittently discharged, so as to avoid excessive feed entering the extruder 4 causing accumulation and blocking the extruder 4, and the extruded feed falls into the collecting box 7 through the discharge port 5, thereby completing the expansion work.

[0026] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments or to make equivalent substitutions for some of the technical features therein.
