Description

Technical Field

[0001] This utility model relates to the field of water filtration technology, and in particular to a separation filtration device. Background Technology

[0002] The coke oven's flue gas dust removal vents are equipped with water seals. The overflow water from these seals contains impurities such as coke powder and slag. To prevent these impurities from clogging the pipes, the overflow water needs to be filtered during discharge. However, cleaning the filter residue inside the filtration device is inconvenient due to the continuous flow of the overflow water. To address these issues, a separate filtration device is proposed. Summary of the Invention

[0003] Purpose of the invention: In order to overcome the shortcomings of the existing technology, this utility model provides a separation filter device that can separate the cleaning zone and the filtration zone in the filter device, so that the cleaning of filter residue is not affected by water flow and is convenient to operate.

[0004] Technical solution: To achieve the above objectives, the present invention provides a separation filtration device, including a filter chamber with an inlet and an outlet. The filter chamber contains a rotatable rotating frame, on which several hollow filter units are radially distributed. Each hollow filter unit contains a detachable partition, which divides the filter chamber into a filtration zone and a cleaning zone. As the rotating frame rotates, the filtration zone and the cleaning zone can be interchanged.

[0005] Furthermore, the hollow filter unit includes a support frame, one end of which is connected to a rotating frame, and the other end of which is attached to the inner wall of the filter chamber; the support frame has a hollow cavity for accommodating partitions, and filter screens are respectively arranged on opposite sides of the hollow cavity.

[0006] Furthermore, the top of the hollow cavity is a socket, through which the partition can be detachably inserted into the hollow cavity.

[0007] Furthermore, a lifting handle is provided above the partition.

[0008] Furthermore, the filter chamber is a circular chamber, and the support frame and the hollow cavity are both arranged radially along the filter chamber.

[0009] Furthermore, the end of the support frame that is attached to the inner wall of the filter chamber is the wall-attached end, and the wall-attached end is provided with an elastic movable member; after the partition is inserted into the hollow cavity, it pushes the elastic movable member against the inner wall of the filter chamber, generating a frictional force between the elastic movable member and the inner wall of the filter chamber that hinders the rotation of the rotating frame.

[0010] Furthermore, the elastic movable component includes an elastic strip disposed outside the wall-attached end, with a movable block connected to the elastic strip. The movable block extends from the connecting groove on the wall-attached end into the hollow cavity. After the partition is inserted into the hollow cavity, the movable block pushes the elastic strip against the inner wall of the filter chamber.

[0011] Furthermore, a rod is provided at the center of the filter chamber, and a sleeve is provided at the center of the rotating frame, the sleeve being rotatably fitted onto the rod.

[0012] Furthermore, a rotating handle is provided above the sleeve.

[0013] Beneficial effects: The present invention provides a separation filtration device, in which a rotatable rotating frame is provided in the filtration chamber, and several hollow filtration units are radially distributed on the rotating frame. Each hollow filtration unit has a detachable partition, which divides the filtration chamber into a filtration area and a cleaning area. When cleaning the filter residue in the cleaning area, it can be free from the influence of water flow, making operation convenient. Attached Figure Description

[0015] Appendix Figure 2 This is a schematic diagram of the rotating frame.

[0016] Appendix Figure 3 This is a schematic diagram of the rotating frame inside the filter chamber. Detailed Implementation

[0017] The present invention will be further described below with reference to the accompanying drawings.

[0018] As attached Figures 1 to 3 The aforementioned separation filtration device includes a filter chamber 1, which has an inlet 2 and an outlet 3. The height of the inlet 2 is higher than the height of the outlet 3. Wastewater enters the filter chamber 1 through the inlet 2, and the filtered water flows out through the outlet 3.

[0019] The filter chamber 1 contains a rotatable frame 4 with several hollow filter units radially distributed on it. A filter cavity is formed between two adjacent hollow filter units, where filter cake accumulates after water filtration. Each hollow filter unit contains a removable baffle 5 that blocks water flow. With the cooperation of multiple baffles 5, the filter chamber 1 can be divided into a filtration zone 6 and a cleaning zone 7. Wastewater flows into the filtration zone 6 from the inlet 2, passes through at least one hollow filter unit without a baffle 5, and then flows out from the outlet 3. The cleaning zone 7 is separated from the filtration zone 6 by at least two baffles 5. Cleaning the filter cake in the cleaning zone 7 is not affected by water flow, facilitating operation. The filtration zone 6 and cleaning zone 7 can be switched as the frame 4 rotates. When there is too much filter cake in the filtration zone 6, the frame 4 is rotated to switch the filtration zone 6 to the cleaning zone 7, where the filter cake is then cleaned.

[0020] The hollow filter unit includes a support frame 8, one end of which is integrally connected to the rotating frame 4, and the other end of which is attached to the inner wall of the filter chamber 1. The support frame 8 has a hollow cavity 9 that accommodates the partition 5, and filter screens 10 are respectively arranged on opposite sides of the hollow cavity 9 to filter the water flow.

[0021] The top of the hollow cavity 9 is a socket, through which the partition 5 is detachably inserted into the hollow cavity 9. A lifting handle 11 is provided above the partition 5, which facilitates the insertion and removal of the partition 5.

[0022] The filter chamber 1 is a circular chamber. The support frame 8 and the hollow cavity 9 are both arranged radially along the filter chamber 1, so that during the rotation of the rotating frame 4, one end of the support frame 8 can remain in contact with the inner wall of the filter chamber 1.

[0023] The end of the support frame 8 that abuts against the inner wall of the filter chamber 1 is called the wall-attached end 12, and the wall-attached end 12 is equipped with an elastic movable element. After the partition 5 is inserted into the hollow cavity 9, the partition 5 will push the elastic movable element against the inner wall of the filter chamber 1, generating a frictional force between the elastic movable element and the inner wall of the filter chamber 1 that hinders the rotation of the rotating frame 4, thereby fixing the position of the rotating frame 4. After the partition 5 is pulled out from the hollow cavity 9, the elastic movable element and the inner wall of the filter chamber 1 are no longer in close contact, and the rotating frame 4 can now rotate within the filter chamber 1.

[0024] As attached Figure 2As shown, the elastic movable component includes an elastic strip 13 disposed outside the wall-attached end 12. The wall-attached end 12 of the support frame 8 has a side groove 16 for accommodating the elastic strip 13. A connecting groove 15 is provided on the wall-attached end 12 of the support frame 8, connecting the side groove 16 and the hollow cavity 9. A movable block 14 is connected to the elastic strip 13, extending from the connecting groove 15 into the hollow cavity 9. After the partition plate 5 is inserted into the hollow cavity 9, the partition plate 5 pushes the elastic strip 13 outwards through the movable block 14, forcing the elastic strip 13 against the inner wall of the filter chamber 1, making the elastic strip 13 adhere tightly to the inner wall of the filter chamber 1. This increases the friction between the two, preventing the rotating frame 4 from rotating under the action of water flow.

[0025] A rod 17 is provided at the center of the filter chamber 1, and a sleeve 18 is provided at the center of the rotating frame 4. The sleeve 18 is rotatably fitted onto the rod 17. A rotating handle 19 is provided above the sleeve 18, which facilitates the rotation of the rotating frame 4.

[0026] Combined with appendix Figure 3 This invention provides a working embodiment: the angle between the inlet 2 and outlet 3 on the filter chamber 1 is between 90 and 180 degrees. Four support frames 8 are arranged in a cross shape on the rotating frame 4, sequentially arranged counterclockwise as support frame 801, support frame 802, support frame 803, and support frame 804. Initially, support frame 801 is located between the inlet 2 and outlet 3. Support frames 801 and 803 have no partitions 5, while support frames 802 and 804 have partitions 5, thus dividing the filter chamber 1 into a filtration zone 6 and a cleaning zone 7. As filter residue gradually accumulates between support frames 801 and 802, it needs to be cleaned. Therefore, firstly, remove the partition 5 inside the second support frame 802 and the fourth support frame 804, so that the elastic strip 13 is no longer tightly attached to the inner wall of the filter chamber 1. Then, rotate the rotating frame 4 counterclockwise by 90 degrees, so that the fourth support frame 804 is rotated between the liquid inlet 2 and the liquid outlet 3. Then, insert the partition 5 into the first support frame 801 and the third support frame 803. The partition 5 squeezes the elastic strip 13, fixing the position of the rotating frame 4. At this time, the filter residue between the first support frame 801 and the second support frame 802 can be cleaned. The filtration device of this utility model can be applied to the filtration of coke oven water seal overflow water, and can also be applied to other wastewater filtration scenarios.

[0027] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
