Technical Field

[0001] The invention relates to a degreasing device for brewing sludge, belonging to the technical field of sludge treatment. Background Art

[0002] With the booming winemaking industry, the amount of sludge generated during the brewing process has also increased year by year. If improperly handled, this sludge can easily pollute the environment. Currently, degreasing is required during the degreasing process. Existing degreasing equipment primarily uses centrifugal degreasing, which can easily cause filter blockage, preventing the oil from being removed. Summary of the Invention

[0003] In order to solve the technical problems existing in the prior art, the present invention provides a brewing sludge degreasing device which has a reasonable design and can separate oil from brewing sludge.

[0004] To achieve the above-mentioned purpose, the technical solution adopted by the present invention is a degreasing device for brewing sludge, comprising an outer cylinder and an inner cylinder, the inner cylinder being installed on the inner wall of the outer cylinder through a rotating support assembly, a first pulley being installed on the outside of the inner cylinder, a driving motor being installed on the outer wall of the outer cylinder, a second pulley being installed on the driving motor, the first pulley and the second pulley being connected by belts, a sealing cover being installed on the top of the outer cylinder, a negative pressure suction pipe being provided on the sealing cover, a heating degreasing assembly being installed on the bottom of the inner cylinder, a fat receiving plate being installed below the inner cylinder, both sides of the fat receiving plate being fixed to the bottom of the outer cylinder by connecting rods, a discharge pipe being also installed on the fat receiving plate, a guide hopper being installed at the bottom of the discharge pipe, and the guide hopper being fixed to the bottom of the outer cylinder through a connecting frame.

[0005] Preferably, the heating and degreasing assembly includes a conical material cone and a heating rod, the conical material cone is arranged at the bottom of the inner cylinder, and a grease guide cavity is formed between the conical material cone and the bottom of the inner cylinder, the surface of the conical material cone is provided with a plurality of grease holes connected with the grease guide cavity, the bottom of the grease guide cavity is provided with a plurality of grease droppers, the grease droppers are connected with the grease receiving pan, a heating rod is installed in the middle of the conical material cone, the bottom of the heating rod passes through the bottom plate of the inner cylinder and the grease receiving pan, and an insulating sealing tube is provided between the heating rod and the bottom plate of the inner cylinder and the grease receiving pan, the bottom of the heating rod is connected with a collector ring, and the top of the heating rod extends to the upper part of the inner cylinder.

[0006] Preferably, a plurality of material guide grooves are further provided on the conical material cone, and the grease holes are provided in the material guide grooves.

[0007] Preferably, the material guide trough is covered with a fine metal mesh.

[0008] Preferably, a heat insulation layer is further provided on the outer wall of the inner cylinder.

[0009] Compared with the existing technology, the present invention has the following technical effects: the present invention has a simple structure and a reasonable design, and adopts a centrifugal heating variable speed degreasing method. By placing the brewing sludge in the inner drum, the rotation of the inner drum is controlled by a driving motor. The driving motor adopts a variable frequency design and can perform variable speed rotation within a set speed range. The intermittent movement enables the brewing sludge in the inner drum to slowly precipitate the oil from the sludge by heating, and the oil slowly flows to the conical material cone and is separated through the grease hole. At the same time, under the action of centrifugal force, the sludge and the conical material cone can always maintain a "separate but not separated" state, and the sludge will not block the grease hole, thereby ensuring that the oil can be discharged quickly and avoiding the problem of blockage.

[0013] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0014] like Figures 1 to 3 As shown, a degreasing device for brewing sludge comprises an outer cylinder 1 and an inner cylinder 2, the inner cylinder 2 is mounted on the inner wall of the outer cylinder 1 through a rotating support assembly 3, a first pulley 4 is mounted on the outside of the inner cylinder 2, a driving motor 5 is mounted on the outer wall of the outer cylinder 1, a second pulley 6 is mounted on the driving motor 5, the first pulley 4 and the second pulley 6 are connected by belts, a sealing cover 7 is mounted on the top of the outer cylinder 1, a negative pressure suction pipe 8 is arranged on the sealing cover 7, a heating degreasing assembly is mounted on the bottom of the inner cylinder 2, a fat receiving pan 9 is mounted below the inner cylinder 2, both sides of the fat receiving pan 9 are fixed to the bottom of the outer cylinder 1 through connecting rods 10, a discharge pipe 11 is further mounted on the fat receiving pan 9, a guide hopper 12 is mounted at the bottom of the discharge pipe 11, and the guide hopper 12 is fixed to the bottom of the outer cylinder 1 through a connecting frame 13.

[0015] The present invention places iron-removed brewing sludge into an inner drum 2. A heating and degreasing assembly heats the sludge, while a drive motor 5, utilizing a variable frequency motor, precisely controls its speed, driving the inner drum via a first pulley 4 and a second pulley 6. Under the influence of high temperature and centrifugation, fat gradually precipitates from the brewing sludge, passes through the heating and degreasing assembly, enters a fat collecting pan 9, and finally enters a guide hopper 12 for recovery. The outer wall of the inner drum 2 is also provided with a thermal insulation layer, which provides thermal insulation.

[0016] Among them, the heating and degreasing component includes a conical material cone 14 and a heating rod 15. The conical material cone 14 is arranged at the bottom of the inner cylinder 2, and a grease guide cavity 16 is formed between the conical material cone 14 and the bottom of the inner cylinder 2. The surface of the conical material cone 14 is provided with a plurality of grease holes 17 connected to the grease guide cavity, and the bottom of the grease guide cavity 16 is provided with a plurality of grease droppers 18. The grease droppers 18 are connected to the grease receiving pan 9. A heating rod 15 is installed in the middle of the conical material cone 14. The bottom of the heating rod 15 passes through the bottom plate of the inner cylinder 2 and the grease receiving pan 9, and an insulating sealing tube 19 is provided between the heating rod 15 and the bottom plate of the inner cylinder 2 and the grease receiving pan 9. The bottom of the heating rod 15 is connected to a collector ring 20, and the top of the heating rod 15 extends to the upper part of the inner cylinder 2.

[0017] The heating and degreasing component can heat the brewing sludge and filter and separate the grease. The heating rod 15 extends into the inner cylinder 2 to heat the brewing sludge. At the same time, the lower part is located in the grease guide cavity 16, which can also heat the grease in the grease guide cavity to prevent the grease from solidifying. The conical material cone 14 can separate the brewing sludge. During the intermittent movement of the inner cylinder 2, the sludge and the conical material cone 14 can always maintain a "separate but not separated" state. In this way, with the heating of the heating rod 15, the grease can be quickly precipitated, and the sludge accumulation and clogging of the grease holes can be avoided. The conical material cone 14 is also provided with a plurality of guide grooves 21, and the grease holes 17 are provided in the guide grooves 21. The guide grooves 21 are covered with a fine metal mesh. This can better facilitate the filtration of grease, further prevent the sludge from clogging the grease holes, and further improve the sludge collection efficiency.
