Description

Technical Field

[0001] The invention relates to a device and method for treating brewing sludge epoxy extraction alcohol precipitation powder solids, belonging to the technical field of solid waste treatment. Background Art

[0002] During the winemaking process, precipitated fermentation sludge spontaneously releases saccharification, which is then concentrated and subdivided under high-heat pressure to undergo catalytic reactions. After the wine is produced, the saccharification sediment accumulates at the bottom. The upper sludge can be used as feed and modified agricultural materials, while the remaining sludge is brewing sludge, also known as sludge. The storage and accumulation of this industrial solid waste is a historical problem. The solidified plates are inactive, cohesive blocks with no pores, and lack the conditions for plant growth and survival. This has led to difficulties in solid waste disposal. Over time, the accumulated volume has grown, the hazards of solid waste have continued to increase, treatment issues have intensified, and technical contradictions have become prominent. Summary of the Invention

[0003] In order to solve the technical problems existing in the prior art, the present invention provides a device and method for treating brewing sludge epoxy extraction alcohol precipitation powder solids, which has a simple process, convenient treatment, can recycle the sludge and improve the waste utilization rate.

[0004] To achieve the above-mentioned objectives, the technical solution adopted by the present invention is a processing device for brewing sludge epoxy extraction alcohol precipitation powder solidification, comprising a storage hopper, a first screw conveyor is installed at the bottom of the storage hopper, the first screw conveyor is arranged vertically, a discharge pipe is provided at the lower part of the first screw conveyor, the discharge pipe is connected to the feed pipe of the second screw conveyor, the discharge pipe of the second screw conveyor is connected to the sterilization storage tank, a water spray pipe is installed on the upper circumference of the storage hopper, a plurality of high-temperature steam pipes are installed on the first screw conveyor, a filter cavity is provided at the bottom of the first screw conveyor, a filter plate is provided at the upper part of the filter cavity, a condenser is connected to the filter cavity, the condenser is connected to the condensation tank, the bottom of the condensation tank is connected to a sedimentation tank, a plurality of oxygen injection air pipes are also installed on the second screw conveyor, and a stirring shaft is also connected to the rotating shaft of the first screw conveyor, and the stirring shaft extends into the storage hopper.

[0005] Preferably, the first screw conveyor and the second screw conveyor are both made of high temperature resistant and corrosion resistant materials.

[0006] Preferably, an annular dust collecting hood is installed on the top circumference of the storage hopper, and the annular dust collecting hood is connected to a negative pressure suction pipe for connecting to a dust collector.

[0007] A method for treating brewing sludge epoxy extraction alcohol precipitation powder solids is carried out according to the following steps: a. Put the sludge into the storage hopper and stir and spray it to make it completely loose; b. The loosened sludge enters the first screw conveyor and is catalyzed by high-temperature steam to gelatinize the starch in the sludge. The starch is then filtered into the filter chamber along with the spray water and steam water. After condensation and precipitation, the supernatant is filtered and used for irrigation. c. The remaining sludge is transported through the second screw conveyor and oxygen-containing air is injected through the oxygen-injection air pipe to allow the sludge to fully contact with the air. It is then sent to a sterilization tank for disinfection and then used for compounding and improving ecological fillers.

BRIEF DESCRIPTION OF THE DRAWINGS

[0009] Figure 1 It is a structural schematic diagram of the present invention. DETAILED DESCRIPTION

[0010] 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.

[0011] like Figure 1 As shown, a processing device for alcohol precipitation powder solidified by epoxy extraction of brewing sludge comprises a storage hopper 1, a first screw conveyor 2 is installed at the bottom of the storage hopper 1, the first screw conveyor 2 is arranged vertically, a discharge pipe 3 is provided at the lower part of the first screw conveyor 2, the discharge pipe 3 is connected to the feed pipe of the second screw conveyor 4, the discharge pipe of the second screw conveyor 4 is connected to the sterilization storage tank 5, a water spray pipe 6 is installed on the upper circumference of the storage hopper 1, a plurality of high-temperature steam pipes 7 are installed on the first screw conveyor 2, a filter chamber 8 is provided at the bottom of the first screw conveyor 2, a filter plate 9 is provided on the upper part of the filter chamber 8, a condenser 10 is connected to the filter chamber 8, the condenser 10 is connected to the condensation tank 11, the bottom of the condensation tank 11 is connected to the sedimentation tank 16, a plurality of oxygen injection air pipes 12 are also installed on the second screw conveyor 4, and a stirring shaft 13 is also connected to the rotating shaft of the first screw conveyor 2, and the stirring shaft 13 extends into the storage hopper 1.

[0012] The present invention places the sludge in a storage hopper 1, stirs it through a stirring shaft 13, and sprays the sludge with a water spray pipe 6, so that the compacted sludge can be quickly broken up and moistened. Then, as the first screw conveyor 2 rotates, the sludge slowly enters the first screw conveyor 2. Since the first screw conveyor 2 has a low rotation speed of 25-30 revolutions per minute and a length of 3-5 meters, the sludge has sufficient residence time in the first screw conveyor 2. In this way, when high-temperature steam is injected through the high-temperature steam pipe 7, the starch in the sludge can continue to be quickly gelatinized, so that the starch, spray water, and steam water flow into the bottom of the first screw conveyor 2, and enter the condensation tank 11 after being filtered through the filter plate 9, and then enter the sedimentation tank 16 for sedimentation separation. The separated supernatant can be used for irrigation. The sludge then flows through discharge pipe 3 into second screw conveyor 4, which rotates at a relatively high speed of 50-60 revolutions per minute and is 3 meters long. During this process, oxygen-containing air pipe 12 injects oxygenated air into the sludge, thoroughly mixing it with the air and restoring its vitality. The sludge is then conveyed to sterilization tank 5 for sterilization. After treatment, it can be used to compound and improve ecological fillers.

[0013] The first and second screw conveyors 2, 4 are both made of high-temperature and corrosion-resistant materials. An annular dust hood 14 is mounted on the top circumference of the storage hopper 1. Connected to this hood is a negative pressure suction pipe 15 for connection to a dust collector. This hood absorbs dust from the compacted mud and sludge, preventing it from escaping.

[0014] When using it, please follow the steps below: a. Put the sludge into the storage hopper and stir and spray it to make it completely loose; b. The loosened sludge enters the first screw conveyor and is catalyzed by high-temperature steam to gelatinize the starch in the sludge. The starch is then filtered into the filter chamber along with the spray water and steam water. After condensation and precipitation, the supernatant is filtered and used for irrigation. c. The remaining sludge is transported through the second screw conveyor and oxygen-containing air is injected through the oxygen-injection air pipe to allow the sludge to fully contact with the air. It is then sent to a sterilization tank for disinfection and then used for compounding and improving ecological fillers.

[0015] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the scope of the present invention.
