Description

Technical Field

[0001] This utility model relates to the field of centrifuge technology, and in particular to a filter centrifuge. Background Technology

[0002] A centrifuge is a machine that uses centrifugal force to separate the components of a mixture of liquids and solid particles or liquids. Centrifuges are mainly used to separate solid particles from the liquid in a suspension, or to separate two immiscible liquids of different densities in an emulsion (e.g., separating cream from milk). They can also be used to remove liquid from wet solids, such as in a washing machine to spin-dry wet clothes. Special high-speed tubular centrifuges can also separate gas mixtures of different densities. Utilizing the different settling velocities of solid particles of different densities or sizes in liquids, some sedimentation centrifuges can also classify solid particles according to density or size. Centrifuges are widely used in chemical, petroleum, food, pharmaceutical, mineral processing, coal, water treatment, and shipbuilding industries.

[0003] The main principle of a filter centrifuge is to use the centrifugal force generated by the high-speed rotating centrifugal drum, with an appropriate filter medium inside the centrifugal drum, to accelerate the liquid phase of the solid-liquid mixture out of the drum, while leaving the solid phase on the filter medium inside the drum, thus achieving the effect of separating solids and liquids, or the effect commonly known as dehydration.

[0004] In related technologies, after the filter media has undergone quantitative or timed filtration, the machine needs to be stopped to remove the filter media for cleaning or replacement. This operation requires machine shutdown and the cleaning and replacement of the filter media is relatively frequent, which affects the working efficiency of the centrifuge.

[0005] Therefore, in practical applications, there is a need for a centrifuge that can reduce the frequency of filter media cleaning and replacement, and improve the centrifuge filtration efficiency. Utility Model Content

[0006] To address the problems in related technologies, this application discloses a filter centrifuge that solves the problem in the prior art that centrifuges need to be shut down for cleaning and replacement of filter media, and that the frequent cleaning and replacement affects filtration efficiency.

[0007] To achieve the above objectives, this application provides the following technical solution:

[0008] A filtration centrifuge includes a filter sleeve, a rotating drum inside the filter sleeve, multiple filter holes on the wall of the rotating drum, a centrifugal filter medium on the inner wall of the rotating drum, a motor connected to the rotating drum for centrifugal rotation, a drain chamber between the filter sleeve and the rotating drum, the drain chamber communicating with an outlet, an openable and closable filter cover at the top of the filter sleeve, an inlet at the top of the filter cover, a primary filtration chamber inside the filter cover, an inlet end communicating with the inlet, an outlet end communicating with the rotating drum, and multiple primary filter media removably disposed inside the primary filtration chamber.

[0009] As a further aspect of this application: each of the primary filter media is provided with a disassembly handle on its outer side.

[0010] As a further aspect of this application: the bottom of the filter cover is provided with a protective plate, and the protective plate is provided with multiple through holes to facilitate the passage of liquid.

[0011] As a further aspect of this application: the primary filtration chamber is provided with a partition in the center, the partition dividing the primary filtration chamber into two primary filtration sub-chambers, the primary filtration sub-chambers being connected to the liquid inlet and the rotating drum respectively, and each primary filtration sub-chamber being provided with multiple primary filtration media that can be inserted and removed.

[0012] As a further aspect of this application: the liquid inlet is connected to a first liquid inlet and a second liquid inlet, which are respectively connected to the primary filtration chamber. The first liquid inlet and the second liquid inlet are respectively provided with control valves at the liquid inlet end, and the opening and closing of the control valves can control the liquid supply accordingly.

[0013] In summary, the beneficial effects of this application are as follows:

[0014] 1. Filter-type centrifuge: The filter sleeve contains a rotating drum and centrifugal filter media. The drum rotates centrifugally under the action of a motor. A drain chamber is provided between the filter sleeve and the drum, and the drain chamber is connected to the outlet. The top of the filter sleeve has an openable and closable filter cover, and the top of the filter cover is connected to an inlet. The liquid enters the rotating drum through the inlet and undergoes efficient filtration through the centrifugal filter media. After purification, the liquid phase is discharged through the drain chamber and the outlet. Solid particles are adsorbed on the centrifugal filter media. The filter cover contains a primary filter chamber, with the inlet end connected to the inlet and the outlet end connected to the drum. The primary filter chamber contains multiple removable primary filter media. Before entering the drum for centrifugal filtration, the liquid first undergoes primary filtration through multiple primary filter media, which can effectively reduce the content and diameter of solid particles in the liquid entering the drum, reduce the amount of centrifugal filter media filtered, extend the cleaning and replacement time of the centrifugal filter media, reduce the cleaning and replacement frequency of the centrifugal filter media, and improve the centrifuge filtration efficiency.

[0015] 2. The pre-filter chamber contains multiple removable pre-filter media. Each pre-filter media has a removal handle on the outside, allowing for easy insertion and removal of the pre-filter media. Changing or cleaning the pre-filter media can be done while the centrifuge is running, improving the centrifuge's filtration efficiency. The materials of the multiple pre-filter media can be the same or different. Using the same filter media provides a backup effect; inserting a new pre-filter media allows for simultaneous removal of the old one, further improving filtration efficiency. Using different filter media expands the pre-filter range, further enhancing filtration efficiency.

[0016] 3. The bottom of the filter cover is equipped with a protective plate with multiple through holes to facilitate liquid passage. Under the premise of liquid passage, the protective plate can effectively isolate the primary filter chamber and the rotating drum, and protect the primary filter chamber and the rotating drum respectively.

[0017] 4. A partition is provided in the center of the primary filtration chamber, which divides the primary filtration chamber into two primary filtration sub-chambers. The primary filtration sub-chambers are connected to the liquid inlet and the rotating drum, respectively. Multiple primary filtration media can be inserted and removed into each primary filtration sub-chamber. The two primary filtration sub-chambers realize the purpose of alternating online and standby operation, thereby improving filtration efficiency.

[0018] 5. The liquid inlet is connected to a liquid inlet 1 and a liquid inlet 2. Each liquid inlet 1 and liquid inlet 2 is equipped with a control valve at the liquid inlet end. The opening and closing of the control valve can control the liquid supply accordingly, providing convenient conditions for the replacement and cleaning of the primary filter media.

[0027] To further understand the content, features, and effects of this application, the following embodiments are provided, and detailed descriptions are given below in conjunction with the accompanying drawings:

[0028] like Figure 1 As shown:

[0029] A filter centrifuge includes a filter sleeve 1, a rotating drum 2 inside the filter sleeve 1, multiple filter holes on the wall of the rotating drum 2, a centrifugal filter medium 3 on the inner wall of the rotating drum 2, and a motor 4 connected to the rotating drum 2 for power connection, which can drive the rotating drum 2 to rotate centrifugally.

[0030] A drain chamber 5 is provided between the filter sleeve 1 and the drum 2. The drain chamber 5 is connected to the outlet 6. The top of the filter sleeve 1 is provided with an openable and closable filter cover 7. The top of the filter cover 7 is connected to an inlet 8.

[0031] The filter cover 7 has a primary filtration chamber 9 inside. The liquid inlet of the primary filtration chamber 9 is connected to the liquid inlet 8, and the liquid outlet of the primary filtration chamber 9 is connected to the rotating drum 2. The center of the primary filtration chamber 9 has a partition 13, which divides the primary filtration chamber 9 into two primary filtration sub-chambers 14. The primary filtration sub-chambers 14 are respectively connected to the liquid inlet 8 and the rotating drum 2. The primary filtration sub-chambers 14 are each equipped with multiple primary filtration media 10 that can be inserted and removed.

[0032] Each primary filter medium 10 has a disassembly handle 11 on its outer side.

[0033] The bottom of the filter cover 7 is provided with a protective plate 12, which has multiple through holes to facilitate the passage of liquid.

[0034] The liquid inlet 8 is connected to a liquid inlet 15 and a liquid inlet 2 16. The liquid inlet 15 and the liquid inlet 2 16 are respectively connected to the primary filtration chamber 14. The liquid inlet 15 and the liquid inlet 2 16 are respectively equipped with control valves 17 at the liquid inlet end. The opening and closing of the control valves 17 can control the liquid supply accordingly.

[0035] In practical applications:

[0036] The filter sleeve 1 contains a rotating drum 2 and a centrifugal filter medium 3. The rotating drum 2 rotates centrifugally under the action of a motor 4. A drain chamber 5 is provided between the filter sleeve 1 and the rotating drum 2, and the drain chamber 5 is connected to the outlet 6. The top of the filter sleeve 1 is provided with an openable and closable filter cover 7, and the top of the filter cover 7 is connected to an inlet 8. The liquid enters the centrifugally rotating drum 2 through the inlet 8 and undergoes efficient filtration through the centrifugal filter medium 3. After purification, the liquid phase is discharged through the drain chamber 5 and the outlet 6, while the solid particles are adsorbed onto the centrifugal filter medium 3. The system includes a primary filtration chamber 9, with its inlet end connected to the inlet port 8 and its outlet end connected to the rotating drum 2. Multiple primary filtration media 10 are removably inserted into the primary filtration chamber 9. Before entering the rotating drum 2 for centrifugal filtration, the liquid undergoes primary filtration through these multiple primary filtration media 10. This effectively reduces the content and diameter of solid particles in the liquid entering the rotating drum 2, decreases the filtration volume of the centrifugal filter media 3, extends the cleaning and replacement time of the centrifugal filter media 3, reduces the cleaning and replacement frequency of the centrifugal filter media 3, and improves the centrifuge's filtration efficiency.

[0037] The pre-filter chamber 9 is equipped with multiple pre-filter media 10 that can be inserted and removed. Each pre-filter media 10 has a disassembly handle 11 on the outside. The pre-filter media 10 can be easily inserted and removed by disassembling the handle 11. The replacement and cleaning of the pre-filter media 10 can be carried out while the machine is running, which improves the filtration efficiency of the centrifuge.

[0038] The materials of the multiple primary filter media 10 can be the same or different. The same filter media can achieve a backup effect. Inserting a new primary filter media 10 can simultaneously remove the old primary filter media 10, thus improving the filtration efficiency. Different filter media can increase the primary filtration range and further improve the filtration efficiency.

[0039] The bottom of the filter cover 7 is provided with a protective plate 12. The protective plate 12 has multiple through holes to facilitate the passage of liquid. Under the premise that liquid passes through, the protective plate 12 can effectively isolate the primary filter chamber 9 and the rotating drum 2, and protect the primary filter chamber 9 and the rotating drum 2 respectively.

[0040] The primary filtration chamber 9 is provided with a partition 13 in the center, which divides the primary filtration chamber 9 into two primary filtration sub-chambers 14. The primary filtration sub-chambers 14 are respectively connected to the liquid inlet 8 and the rotating drum 2. The primary filtration sub-chambers 14 are provided with multiple primary filtration media 10 that can be inserted and removed. The two primary filtration sub-chambers 14 realize the purpose of alternating online and standby operation, thereby improving filtration efficiency.

[0041] The liquid inlet 8 is connected to a liquid inlet 15 and a liquid inlet 2 16. The liquid inlet 15 and the liquid inlet 2 16 are respectively equipped with control valves 17 at the liquid inlet end. The opening and closing of the control valves 17 can control the liquid supply accordingly, which provides convenient conditions for the replacement and cleaning of the primary filter medium 10.

[0042] Finally, it should be noted that the above disclosure is merely a preferred embodiment of this application and is not intended to limit this application. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
