Description

Technical Field

[0001] The invention relates to the technical field of centrifuges, and more particularly to an automatic continuous flow-guiding bottom-discharging centrifuge. Background Art

[0002] In the chemical, pharmaceutical, food processing and other industrial fields, centrifuges are the core equipment for solid-liquid separation. Their continuous operation capacity and separation efficiency directly affect the stability and economy of the production process. Traditional bottom-discharging centrifuges usually use a single filtration structure. During long-term operation, the filter plate is prone to pore clogging due to the interception of solid matter, resulting in a decrease in separation efficiency.

[0003] Although some improved centrifuges have tried to alleviate the shutdown problem through multi-chamber design or backwashing structure, the filter switching mechanism in the existing technology generally has defects such as complex structure, poor sealing, and long switching cycle, making it difficult to achieve true continuous diversion and synchronous cleaning. For example, some equipment uses a rotating switching filter plate, but there is still material leakage or pressure fluctuation during the switching process, resulting in solid phase residue or liquid turbidity; and centrifuges with built-in spray cleaning often have incomplete filter plate regeneration due to flushing dead corners, and still face the risk of clogging after long-term operation.

[0004] Based on this, we provide an automatic continuous flow-guiding bottom-discharging centrifuge. Summary of the invention

[0005] In order to solve the problems raised in the above background technology, the present invention provides an automatic continuous flow-guiding bottom-discharging centrifuge, which can automatically switch filter elements during operation to achieve simultaneous centrifugal separation and filter element cleaning, avoiding production interruptions caused by shutdown for filter element replacement in traditional centrifuges. It is particularly suitable for industrial scenarios that require continuous operation and can improve production efficiency.

[0006] The present invention provides an automatic continuous flow-guiding bottom-discharging centrifuge adopts the following technical solution:

[0007] An automatic continuous flow-guiding bottom-discharging centrifuge comprises a centrifugal box for centrifugally treating fluids, wherein a centrifugal wheel is arranged inside the centrifugal box, and an inlet and outlet member is also arranged inside the centrifugal box; a driving member is arranged on the side of the centrifugal box and is used to drive the centrifugal wheel to rotate; a filtering mechanism is arranged on the side of the centrifugal box and is used to separate the fluid after centrifugation from solid and liquid; a discharge mechanism is arranged in the centrifugal box and is used to discharge solid substances on the filtering mechanism; wherein the filtering mechanism comprises a switching box fixedly arranged on the side of the centrifugal box; a pair of filtering elements, one of which is arranged in the centrifugal box and the other is arranged in the switching box; and a pair of electric push cylinders, both of which are arranged on the side of the centrifugal box and are used to drive the corresponding filtering elements to move.

[0008] Preferably, the filter element comprises an L-shaped plate slidably arranged between the centrifugal box and the switching box, an assembly groove is provided on the top of the L-shaped plate, a filter plate is detachably arranged inside the assembly groove, and the output end of the electric push cylinder is connected to the side of the L-shaped plate.

[0009] Preferably, the discharge mechanism includes two nozzles fixedly arranged on one side of the centrifugal box, and the two nozzles correspond to the positions of two L-shaped plates, and two discharge valves are arranged on the other side of the centrifugal box, and the two discharge valves correspond to the positions of two L-shaped plates.

[0010] Preferably, the side surfaces of the L-shaped plate form a barrier for discharging separated solids, and the side surfaces of the L-shaped plate can be arranged within the side walls of the centrifuge box.

[0011] Preferably, a sprayer is further provided inside the switching box, and the sprayer corresponds to the side end position of the L-shaped plate, and a drainage pipe is provided at the bottom of the switching box.

[0012] Preferably, the driving member comprises a base, a motor is arranged on the top of the base, and an output end of the motor is connected to the centrifugal wheel.

[0013] Preferably, the feed and discharge member comprises a feed pipe and a drain pipe, the feed pipe is connected and arranged at the top of the centrifuge box, and the drain pipe is connected and arranged at the bottom of the centrifuge box.

[0014] Preferably, solenoid valves are provided inside the feed pipe and the drain pipe.

[0015] In summary, the present invention includes the following beneficial technical effects:

[0016] 1. The centrifugal wheel is driven to rotate in the centrifugal box by the driving member, and then the raw materials to be centrifuged are input into the centrifugal box through the inlet and outlet members. After the raw materials are centrifuged, the solids are arranged on the filter element, and the liquid flows through the filter element to the bottom of the centrifugal box and is discharged through the inlet and outlet members. After a filter element has been used for a period of time, the filter element in the switching box is driven by the electric push cylinder to move into the centrifugal box, and then another electric push cylinder drives the filter element in the centrifugal box to move into the switching box, thereby replacing the filter element, and the filter element collected in the switching box is cleaned of solids through the discharge mechanism. Through this structural design, the filter element can be automatically switched during operation, and centrifugal separation and filter element cleaning can be carried out simultaneously, avoiding production interruptions caused by stopping the traditional centrifuge to replace the filter element. It is especially suitable for industrial scenarios that require continuous operation and can improve production efficiency.

[0017] 2. When the high side of the L-shaped plate forms a channel with the side of the switching box, water is sprayed through the nozzle box channel and the corresponding discharge valve is opened to clean up the solids. Through this structural design, the discharge mechanism automatically cleans the solid matter in the switching box, reducing manual intervention.

[0018] 3. After the L-shaped plate is arranged in the switching box, the filter plate can be completely arranged in the switching box. The filter plate on the L-shaped plate can be flushed by the sprayer to reduce the problem of filter plate blockage and avoid the reduction of separation efficiency of the centrifuge due to blockage of the filter plate pores. Compared with manual cleaning or shutdown and disassembly flushing, automatic spraying can extend the continuous use cycle of the filter plate.

[0030] Among them, the filtering mechanism 3 includes a switching box 300, a pair of filter elements and a pair of electric push cylinders 301; the switching box 300 is fixedly set on the side of the centrifugal box 1; a pair of filter elements, one is set in the centrifugal box 1, and the other is set in the switching box 300; the pair of electric push cylinders 301 are both set on the side of the centrifugal box 1, and are used to drive the corresponding filter elements to move.

[0031] Specifically, the centrifugal wheel 2 is driven to rotate in the centrifugal box 1 by a driving member, and then the raw materials to be centrifugally separated are input into the centrifugal box 1 through the inlet and outlet member.

After a filter element has been used for a period of time, the filter element in the switching box 300 is driven to move into the centrifugal box 1 by the electric push cylinder 301, and then the filter element in the centrifugal box 1 is driven to move into the switching box 300 by another electric push cylinder 301, thereby replacing the filter element, and the filter element received in the switching box 300 is cleaned of solids through the discharge mechanism 4.

[0032] Through this structural design, the filter elements can be automatically switched during operation, achieving simultaneous centrifugal separation and filter element cleaning, avoiding production interruptions caused by traditional centrifuge shutdowns to replace filter elements.
