Description

Technical Field

[0001] This invention relates to the field of wastewater treatment technology, specifically to a pretreatment device for brewing wastewater. Background Technology

[0002] The main components of brewing wastewater include organic matter, solids, and ammonia nitrogen. Organic matter primarily originates from the brewing process, such as waste wine, spent yeast, fruit pomace, and brewing sludge. Solids include suspended solids and ionic compounds; suspended solids mainly come from waste wine and spent yeast, while ionic compounds primarily arise from pH adjustments and washing processes. Ammonia nitrogen originates from the decomposition of proteins in the wastewater. In addition, brewery wastewater also contains other harmful elements, such as copper and zinc ions.

[0003] To address the issue of wastewater discharge from wineries, treatment is necessary. Commonly used methods include: physical methods – such as sedimentation, filtration, and aeration – to separate harmful substances from the wastewater and purify it; chemical methods – such as oxidation, reduction, precipitation, and ion exchange – to remove pollutants by adding chemical agents; and biological methods – to treat the wastewater by introducing microorganisms and plants, utilizing natural biodegradation to purify the wastewater.

[0004] When treating brewing wastewater, due to its complex composition and the presence of brewing sludge and impurities, direct treatment can hinder the immediate reaction between chemical components or microorganisms and the wastewater. This can result in the wastewater being discharged along with the sludge and impurities before it has been properly treated or fully treated, thus still causing environmental damage and impacting ecological security. Summary of the Invention

[0005] The present invention aims to provide a pretreatment device for brewing wastewater to solve the problem that residual sludge and impurities in brewing wastewater clog the device due to agglomeration during separation and treatment, resulting in a slow flow rate of brewing wastewater.

[0006] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a pretreatment device for brewing wastewater, comprising a tank, a partition, a separation component, an inlet disposed at the top of the tank, and a first outlet and a second outlet disposed at the bottom of the tank. The partition is arranged in a ring around the tank, and the top of the partition has a slot. The space inside the partition is a compartment, and a transmission component is disposed at the bottom of the compartment. The transmission component is used to drive the wastewater and sludge impurities to mix evenly. There is a gap between the partition and the tank. The separation component that separates the sludge impurities from the wastewater is disposed in the gap. The wastewater flows out from the first outlet, and the sludge impurities flow out from the second outlet.

[0007] The working principle of this invention is as follows: the brewing wastewater is injected into the tank through the inlet. When the brewing wastewater reaches the compartment, it begins to rotate centrifugally under the action of the transmission component. During the rotation, the sludge and impurities are broken up and evenly dispersed in the brewing wastewater. At this time, the brewing wastewater flows from the slot through the separation component to the bottom of the tank. The separated brewing wastewater flows out from the first outlet, and the sludge and impurities flow out from the second outlet.

[0008] The beneficial effects of this invention are as follows: The transmission component drives the brewing wastewater in the compartment to rotate, so that the sludge and other impurities in the brewing wastewater can be mixed evenly with the water. After passing through the compartment, the brewing wastewater is transported by the separation component. After separation, the wastewater and sludge impurities in the brewing wastewater are separated, so that the wastewater can be treated more thoroughly in the next step. The separated sludge impurities will not clog the device. Under the continuous flushing of the brewing wastewater, the sludge impurities will continue to flow until they flow out of the box.

[0009] Furthermore, the transmission assembly includes a chassis, a turntable, and a motor. The chassis is connected to the inner bottom of the compartment, and the turntable is connected to the top of the chassis. A rotating block is arranged around the top of the turntable. A base is located at the inner bottom of the housing, and the motor is connected inside the base. The motor's output shaft passes upward through the base and chassis and connects to the turntable. During operation, the motor is started, and its output shaft drives the turntable to rotate. At this time, multiple rotating blocks follow the turntable's rotation, causing the brewing wastewater inside the compartment to rotate.

[0010] Furthermore, a rotating rod is connected to the top of the turntable, and multiple cleaning rods are connected to the side wall of the rotating rod, with cleaning blades attached to each cleaning rod. The cleaning blades allow sludge and impurities adhering to the inner wall of the partition to be scraped off.

[0011] Furthermore, the separation component includes a spiral channel and an inclined plate. The spiral channel is arranged from top to bottom within the gap between the tank and the partition. The top of the partition has a slot, which is flush with the top of the spiral channel. Each spiral channel has drainage holes. The inclined plate is inclinedly positioned at the bottom of the gap between the tank and the partition. The inclined plate has screening holes. The top of the inclined plate is located at the bottom of the spiral channel and is higher than the first outlet. The bottom of the inclined plate is located at the second outlet. During operation, brewing wastewater flows from the slot of the partition to the spiral channel. Part of the brewing wastewater flows through the drainage holes to the next layer of spiral channel until it reaches the inclined plate. The other part of the brewing wastewater, carrying sludge and impurities, slowly flows through the spiral channel to the inclined plate. After being screened by the screening holes on the inclined plate, the sludge and impurities flow down the inclined plate to the second outlet, while the brewing wastewater flows through the screening holes to the first outlet.

[0012] The spiral channel design reduces the flow rate of the high-speed centrifuged brewing wastewater, allowing sludge and impurities to settle. The drainage holes enable a portion of the brewing wastewater to be quickly separated and enter the next process. The inclined plate located at the bottom of the spiral channel allows the brewing wastewater to pass through it promptly, while the sludge and impurities remaining on the inclined plate are continuously flushed away by the wastewater, preventing sludge and impurities from clogging the plate.

[0013] Furthermore, the partition plate is provided with through holes, located above the bottom of the spiral waterway, and the diameter of the through holes is larger than the size of the sludge and impurities. The through holes allow the brewing wastewater in the middle section of the partition to enter the spiral waterway in a timely manner.

[0014] Furthermore, the diameter of the drainage hole is smaller than the size of the sludge impurities. By limiting the diameter of the drainage hole, the sludge impurities can be screened out.

[0015] Furthermore, the rotating blocks are shaped like raised windmills. The shape of these rotating blocks allows the centrifugal force generated by the turntable to rotate the brewing wastewater more quickly.

[0016] Furthermore, the top of the housing is equipped with a movable cover, and the water inlet is connected to the top of the movable cover. The movable cover allows the top of the housing to be opened, enabling timely observation of the internal components and rinsing. Attached Figure Description
