Description

Technical Field

[0001] The utility model belongs to the technical field of sewage separation, in particular to a water power separation device. Background Art

[0002] Sewage treatment is an important part of the urban water system circulation. Water carries with it a large amount of debris during its flow. The debris is divided into heavy debris that can sink to the bottom of the water and light debris that floats on the water surface. The heavy debris includes cement blocks, sand and gravel, and bricks, while the light debris includes branches, foam boards, and plastic packaging bags. If the heavy debris and light debris are directly landfilled together, some substances in the light debris can easily cause secondary pollution to the environment.

[0003] However, heavy debris and light debris often gather together, causing the light debris to sink to the bottom of the water along with the heavy debris, and the heavy debris and light debris need to be separated and processed. Utility Model Content

[0004] The purpose of the present utility model is to provide a hydrodynamic separation device to solve at least one aspect of the problems and defects raised in the above-mentioned background technology.

[0005] It comprises a separation bin, the bottom of which is connected to the main bin, a water inlet is arranged in the separation bin, a power impeller is arranged below the water inlet, and a crushing roller is arranged below the power impeller;

[0006] An impeller gear is provided on the outside of the separation bin, and the impeller gear is linked to a power impeller inside the separation bin through a first rotating shaft, and a first transmission pulley is provided on the first rotating shaft; a first separation gear is provided below the impeller gear, and a second separation gear is meshed and connected to one side of the first separation gear, the first separation gear is linked to a crushing roller inside the separation bin through the second rotating shaft, and the second separation gear is linked to a crushing roller inside the separation bin through a third rotating shaft, and a second transmission pulley is provided on the rotating shaft of the first separation gear, and the first transmission pulley is connected to the second transmission pulley through a transmission belt.

[0007] Furthermore, the water outlet end of the water inlet faces the blades of the power impeller.

[0008] Furthermore, a separation bucket is provided at the bottom of the separation bin, the separation bucket extends into the main bin, and the bottom of the separation bucket is connected to a spiral separation pipe.

[0009] Furthermore, an overflow port is provided on the main compartment, and the main compartment is connected to the auxiliary compartment through the overflow port.

[0010] Furthermore, a first screen is provided in the main bin, and a second screen is provided in the auxiliary bin.

[0011] Furthermore, a first door is provided outside the main bin, and the first door corresponds to the position of the first screen in the main bin. A second door is provided outside the auxiliary bin, and the second door corresponds to the position of the second screen in the auxiliary bin.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] This solution breaks up and separates light debris from heavy debris through the cooperation of a breaking roller and a spiral separation pipe. The breaking roller breaks up the debris to prevent it from agglomerating. The broken debris enters the spiral separation channel, and the centrifugal force of the spiral channel improves the debris separation effect.

[0014] This solution uses water power as kinetic energy, combined with gear transmission, to drive the breaking rollers for breaking up. The overall design does not involve any power structure, and uses water power to separate debris, which is energy-saving and environmentally friendly. BRIEF DESCRIPTION OF THE DRAWINGS

It should be understood that the specific embodiments described herein are only used to explain the utility model and are not used to limit the utility model, that is, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. The components of the embodiments of the utility model described and shown in the drawings here can be arranged and designed in various different configurations.

[0022] Therefore, the following detailed description of the embodiments of the utility model provided in the accompanying drawings is not intended to limit the scope of the utility model claimed for protection, but merely represents selected embodiments of the utility model. Based on the embodiments of the utility model, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the utility model.

[0023] See also Figure 1-4 As shown, in an embodiment of the utility model, a hydrodynamic separation device includes a separation chamber 1, a water inlet 101 is provided inside the separation chamber 1, a power impeller 1022 is provided below the water inlet 101, the water outlet end of the water inlet 101 is directly opposite to the blades of the power impeller 1022, and two mirror-arranged breaking rollers 105 are provided below the power impeller 1022, and the two breaking rollers 105 are horizontally parallel.

[0024] The separation bin 1 is provided with an impeller gear 1023 on the outside, and the impeller gear 1023 is arranged on the first rotating shaft 1021. The first rotating shaft 1021 extends into the separation bin 1 and is equipped with a power impeller 1022, and the power impeller 1022 and the impeller gear 1023 are kept in linkage through the first rotating shaft 1021; a first separation gear 1032 is provided below the impeller gear 1023, and a second separation gear 1042 is meshed and connected on one side of the first separation gear 1032. The first separation gear 1032 is transmission-connected to a scattering roller 105 inside the separation bin 1 through the second rotating shaft 1031, and the second separation gear 1042 is transmission-connected to another shattering roller 105 inside the separation bin 1 through the third rotating shaft 1041. A first transmission pulley 1032 is provided on the first rotating shaft 1021 outside the separation bin 1 24. A second transmission pulley 1033 is provided on the second rotating shaft 1031, and the first transmission pulley 1024 and the second transmission pulley 1033 are connected through a transmission belt 1025. When in use, sewage is introduced through the water inlet 101, and the sewage impacts the blades of the power impeller 1022, so that the power impeller 1022 starts to rotate, thereby driving the impeller gear 1023 linked with the power impeller 1022 outside the separation chamber 1 to rotate, and the impeller gear 1023 drives the first separation gear 1032 to rotate through the transmission pulley, and the first separation gear 1032 drives the meshing second separation gear 1042 to rotate in the opposite direction, so that the two parallel scattering rollers 105 inside the separation chamber 1 rotate relative to each other, and the sewage flushed down by the power impeller 1022 falls onto the scattering roller 105 to scatter the debris in the sewage.

[0025] In one embodiment, see Figure 4 As shown, the scattering roller 105 is provided with scattering claws 106 , and the scattering claws 106 on adjacent scattering rollers 105 are arranged alternately, and the debris in the sewage is scattered by the scattering claws 106 .

[0026] In one embodiment, see Figure 1 As shown, the bottom of the separation bin 1 is connected to the main bin 2, and a separation bucket 1071 is provided between the inside of the separation bin 1 and the main bin 2. The bottom of the separation bucket 1071 is connected to a spiral separation pipe 1072. The sewage after the debris is broken up by the breaking roller falls into the separation bucket 1071, and falls into the main bin 2 along the spiral separation pipe 1072 connected to the bottom of the separation bucket 1071. The centrifugal force generated by the spiral separation pipe 1072 can better separate the debris in the sewage.

[0027] In one embodiment, see Figure 1 As shown, an overflow port 201 is opened on the main compartment 2, and the auxiliary compartment 3 is connected through the overflow port 201. The outlet of the spiral separation pipe 1072 faces the overflow port 201. Through the impact of the water flow, the light debris floating on the surface of the water flow is driven to enter the auxiliary compartment 3 connected with the overflow port 201.

[0028] In one embodiment, see Figure 1 As shown, the main compartment 2 is provided with a first screen 202, the auxiliary compartment 3 is provided with a second screen 301, the main compartment 2 is provided with a first water outlet 203 at the bottom, the auxiliary compartment 3 is provided with a second water outlet 302, and the first water outlet 203 is provided with a valve, which can freely switch or adjust the first water outlet 203. When in use, the first water outlet 203 is kept closed first, and when the water level reaches the overflow port 201, the first water outlet 203 can be opened to ensure that the water level line is close to the overflow port 201, so that the light debris floating on the surface of the water flow after being broken up can pass through the overflow port 201, and the heavy debris separated from the sewage will sink to the bottom and fall on the first screen 202, and the light debris is blocked by the second screen 301, and the separated water flows out from the first water outlet 203 and the second water outlet 302.

[0029] In one embodiment, see Figure 3 As shown, a first door 204 is provided on the outside of the main compartment 2, and the first door 204 corresponds to the position of the first screen 202 in the main compartment 2. A second door 303 is provided on the outside of the auxiliary compartment 3, and the second door 303 corresponds to the position of the second screen 301 in the auxiliary compartment 3. After the water in the equipment is drained, the first door 204 and the second door 303 can be opened to clean up the debris on the corresponding screen or replace the screen. The first door 204, the second door 303 and the corresponding positions of the main compartment 2 and the auxiliary compartment 3 are all designed with waterproofing.

[0030] The above contents are merely examples and explanations of the structure of the utility model.
