Technical Field

[0001] The utility model relates to the technical field of sewage treatment, and more specifically, to a sewage impurity separation device. Background Art

[0002] At present, in industrial and agricultural production and daily life of residents, a large amount of turbid water containing impurities and suspended substances is generated every day. For example, a large amount of sewage formed in industrial wastewater, agricultural aquaculture, etc. all face the problem of how to energy-efficiently separate a large amount of impurity suspended substances in the sewage and then perform further purification treatment.

[0003] The existing separation of sewage impurities usually uses a physical method of centrifugal separation to separate impurities. However, when centrifugal separation is used to process impurities, the impurities often contain some larger sundries, such as sand and gravel. And the centrifuge lacks a pretreatment device. When the centrifuge separates these impurities, the sundries will impact the inner wall of the centrifuge, causing damage to the centrifuge. Summary of the Utility Model

[0004] In order to overcome the above-mentioned defects of the prior art, an embodiment of the utility model provides a sewage impurity separation device. The technical problem to be solved by the utility model is that the centrifuge lacks a pretreatment device. When the centrifuge separates these large impurities, the sundries will impact the inner wall of the centrifuge, causing damage to the centrifuge.

[0005] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0006] A sewage impurity separation device includes a separation tank. The top surface and the bottom surface of the separation tank are respectively fixedly connected and communicated with a water inlet pipe and a drain pipe. A first filter plate and a baffle are respectively fixedly installed in the separation tank. A lead screw sleeve is slidably connected in the separation tank. The separation tank drives the lead screw sleeve to slide through a driving mechanism. The bottom surface of the lead screw sleeve is elastically connected with a push plate. A brush is installed on the bottom surface of the push plate, and the bottom end of the brush abuts against the top surface of the groove of the first filter plate.

Each material conveying mechanism is connected with the driving mechanism through a gear transmission mechanism. The bottom end of each discharge cylinder is communicated with the separation tank through a return pipe.

[0007] As Figures 1-5 shown, the specific implementation method is: by setting the lead screw sleeve and the driving mechanism, the lead screw sleeve slides reciprocally, thereby driving the push plate to push the large impurities deposited on the first filter plate and pushing them into the discharge cylinder through the connecting channel. Through the material conveying mechanism, the materials in the discharge cylinder are conveyed to the outside, thus avoiding affecting the subsequent centrifuge.

[0008] In a preferred embodiment, the driving mechanism includes a reciprocating lead screw, and the reciprocating lead screw is rotatably connected in the separation box, and the reciprocating lead screw is in threaded connection with the lead screw sleeve. A limiting rod is fixedly installed in the separation box, and the lead screw sleeve is slidably connected with the limiting rod.

[0009] In a preferred embodiment, each of the material conveying mechanisms includes a rotating shaft, and each rotating shaft is rotatably connected in a corresponding discharge cylinder, and spiral blades are installed on the outer side of each rotating shaft.

[0010] In a preferred embodiment, each of the gear transmission mechanisms includes a driving bevel gear, and the driving bevel gear is installed at one end of the reciprocating lead screw. A driven bevel gear is installed at the top end of each rotating shaft, and each driving bevel gear is meshed with a corresponding driven bevel gear.

[0014] In a preferred embodiment, a plurality of water inlet pipes are symmetrically installed on the bottom surface of the separation box. The bottom surface of the separation box is conical, and the support feet are installed at the open end of the cone.

[0015] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0016] 1. By setting devices such as a reciprocating lead screw, a lead screw sleeve, spring telescopic rods, a push plate, a brush, and spiral blades, the present utility model realizes that the first filter plate retains large impurities in the groove, and then through the reciprocating sliding of the lead screw sleeve, the push plate pushes the large impurities in the groove to the bottom of the discharge cylinder, and the spiral blades can be rotated through the gear transmission structure to vertically convey the impurities in the discharge cylinder, and then discharge them through the discharge pipe, so as to pre-treat the sewage, separate the large impurities, and automatically convey them to the outside of the device, achieving the purpose of facilitating subsequent treatment.

[0017] 2. The utility model realizes the purpose of reducing the waste of water during impurity separation by setting devices such as a second filter plate and a reflux pipe, enabling the water body on the vertically transported impurities to penetrate the second filter plate under the action of gravity and then re-enter the separation tank through the reflux pipe.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0025] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0026] Refer to Figures 1-5, A sewage impurity separation device, including a separation tank 1. The top and bottom of the separation tank 1 are respectively fixedly connected and communicated with a water inlet pipe 2 and a drain pipe 3. A first filter plate 10 and a baffle 9 are respectively fixedly installed in the separation tank 1. A lead screw sleeve 13 is slidably connected in the separation tank 1. The separation tank 1 drives the lead screw sleeve 13 to slide through a driving mechanism. The bottom surface of the lead screw sleeve 13 is elastically connected with a push plate 15. A brush 16 is installed on the bottom surface of the push plate 15, and the bottom end of the brush 16 abuts against the top surface of the groove of the first filter plate 10. Connecting channels 5 are respectively fixedly connected and communicated on both sides of the separation tank 1. The other end of each connecting channel 5 is fixedly connected and communicated with a discharge cylinder 6. A material conveying mechanism is provided in each discharge cylinder 6. Each material conveying mechanism is connected to the driving mechanism through a gear transmission mechanism. The bottom end of each discharge cylinder 6 is connected to the separation tank 1 through a return pipe 7.

[0027] As Figures 1-5 shown, the implementation method is specifically as follows: By setting the lead screw sleeve 13 and the driving mechanism, the lead screw sleeve 13 slides reciprocally, thereby driving the push plate 15 to push the large impurities deposited on the first filter plate 10, and pushing them into the discharge cylinder 6 through the connecting channel 5. Through the material conveying mechanism, the materials in the discharge cylinder 6 are conveyed to the outside, thus avoiding affecting the subsequent centrifuge.

[0028] The driving mechanism includes a reciprocating lead screw 11, and the reciprocating lead screw 11 is rotatably connected in the separation tank 1. The reciprocating lead screw 11 is threadedly connected with the lead screw sleeve 13. A limiting rod 12 is fixedly installed in the separation tank 1, and the lead screw sleeve 13 is slidably connected with the limiting rod 12.

[0029] The lead screw sleeve 13 is limited by the limiting rod 12 so that it cannot rotate and can only perform linear sliding.

[0030] Each material conveying mechanism includes a rotating shaft 22, and each rotating shaft 22 is rotatably connected in the corresponding discharge cylinder 6. A spiral blade 23 is installed on the outer side of each rotating shaft 22.

[0031] Through the spiral blade 23, the materials can be vertically conveyed to the upper part and discharged through the discharge pipe 8.

[0032] Each gear transmission mechanism includes a driving bevel gear 20, and the driving bevel gear 20 is installed at one end of the reciprocating lead screw 11. A driven bevel gear 21 is installed at the top end of each rotating shaft 22, and each driving bevel gear 20 meshes with the corresponding driven bevel gear 21.

[0033] Through the gear transmission mechanism, the number of motors 17 used can be reduced, thereby reducing the manufacturing cost of the device.

[0034] A second filter plate 24 is fixedly installed inside each material discharging cylinder 6, and the bottom end of each driven bevel gear 21 is rotatably connected to the top surface of the correspondingly positioned second filter plate 24.

[0035] Through the second filter plate 24, when impurities are vertically conveyed, the water source carried by the impurities will fall due to gravity and pass through the second filter plate 24, thereby being recycled into the separation tank 1 to avoid waste of water.

[0036] A plurality of spring telescopic rods 14 are fixedly installed on the lower section of the lead screw sleeve 13, and the other end of each spring telescopic rod 14 is fixedly connected to the top surface of the push plate 15.

[0037] Through the spring telescopic rods 14, the brush 16 on the bottom surface of the push plate 15 is just in contact with the groove of the first filter plate 10, so as to facilitate pushing the material. At the same time, a number of water permeable holes are provided on the push plate 15.

[0038] A motor 17 is fixedly installed on the outer side of the separation tank 1. Synchronous pulleys 18 are installed on the output shaft of the motor 17 and on the reciprocating lead screw 11, and a synchronous belt 19 is sleeved on the two synchronous pulleys 18.

[0039] A plurality of water inlet pipes 2 are symmetrically installed on the bottom surface of the separation tank 1. The bottom surface of the separation tank 1 is conical, and the support feet 4 are installed at the open end of the cone.

[0040] When the utility model is in use, first, sewage is injected into the separation tank 1 through the water inlet pipe 2. Then, under the action of the baffle 9, the sewage can be separated along both sides of the baffle 9, so that the sewage first contacts the two sides of the first filter plate 10. Then, the water body penetrates downward through the first filter plate 10. At the same time, large impurities slide to the groove in the first filter plate 10 under the action of gravity. Then, the motor 17 is started. Under the action of the synchronous pulley 18 and the synchronous belt 19, the reciprocating lead screw 11 is driven to rotate. With the cooperation of the limit rod 12 and the lead screw sleeve 13, the push plate 15 is driven to slide back and forth. At the same time, under the action of the spring telescopic rod 14, the brush 16 installed on the bottom surface of the push plate 15 is tightly attached to the groove of the first filter plate 10, so as to push the impurities in the groove to the connecting channels 5 on both sides and enter the bottom end of the material discharging cylinder 6 through the connecting channels 5.

[0041] While the reciprocating lead screw 11 rotates, the driving bevel gear 20 and the driven bevel gear 21 drive the rotating shaft 22 to rotate, so as to vertically convey and discharge the impurities through the spiral blade 23. During the conveying process, the water body attached to the impurities drips downward under the action of gravity and enters the reflux pipe 7 through the second filter plate 24 and finally flows into the separation tank 1 to avoid waste of water. Finally, the pretreated sewage can be separated again by connecting the drain pipe 3 to a centrifuge outside.

[0042] Only some exemplary embodiments of the present utility model are described by way of illustration. Undoubtedly, for those of ordinary skill in the art, various modifications can be made to the described embodiments without departing from the spirit and scope of the present utility model. Therefore, the above drawings and description are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present utility model.
