DETAILED DESCRIPTION
[0016] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. 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.
[0017] See also Figure 1-2 , the utility model provides a technical solution:
[0018] An automatic sand screening machine for construction includes a sewage treatment part 1 and a pump body 2, a water supply pipe 3 is provided between the water outlet end of the sewage treatment part 1 and the water inlet end of the pump body 2, a drainage pipe 4 is provided between the water inlet end of the sewage treatment part 1 and the water outlet end of the pump body 2, a feed hopper 5 and a slag discharge part 6 are provided on the water supply pipe 3 in sequence along the water flow direction, the bottom end of the feed hopper 5 is connected to the water supply pipe 3, and a cyclone 7 is provided on the drainage pipe 4.
[0019] When the pump body 2 is working, the clean water in the sewage treatment part 1 will be pumped out through the water supply pipe 3. When the water flows through the feed hopper 5, the discharged sand will be mixed into the water flow, collide with the flow of the water, and be mixed into the water for sufficient cleaning. When passing through the slag discharge part 6, the sand with larger particle size will be removed, stored in the slag discharge part 6 and discharged, and then enter the cyclone 7 through the pump body 2. The principle of centrifugal sedimentation is used to settle the gravel to the bottom of the cyclone 7 and then discharged, while the sewage enters the sewage treatment part 1 through the cyclone 7 and is reused after being treated.
[0020] Among them, a driving mechanism 8 is provided above the feeding hopper 5, and the driving mechanism 8 is transmission-connected to a spiral shaft 9 vertically arranged inside the feeding hopper 5. The bottom end of the spiral shaft 9 extends to the inner side of the water supply pipe 3. The spiral shaft 9 is driven to rotate by the driving mechanism 8 to realize the quantitative addition of sand and gravel, thereby avoiding the problem of blockage of the water supply pipe 3 and the drainage pipe 4.
[0021] The slag discharge part 6 preferably has the following structure: it includes a branch pipe 61 connected to the water supply pipe 3, a first filter screen 62 for filtering out sand and gravel with too large particle size is provided at the connection between the branch pipe 61 and the water supply pipe 3, a valve body 63 is provided at the bottom end of the branch pipe 61, and the first filter screen 62 is inclined.
[0022] The branch pipe 61 is used to temporarily store sand and gravel with larger particle sizes, and then the sand and gravel are discharged by opening the valve body 63. The inclined setting of the first filter screen 62 can increase the flow cross-section on the one hand to prevent gravel from clogging the mesh, and on the other hand it is also conducive to the sand and gravel with larger particles falling into the branch pipe 61.
[0023] The portion of the drain pipe 4 communicating with the cyclone 7 is tangent to the inner wall of the cyclone 7, so that the flow velocity of the water entering the cyclone 7 can be maintained as much as possible, and the velocity drops rapidly in the rapidly increasing internal space of the cyclone 7, which is beneficial to the sedimentation. The liquid outlet at the top of the cyclone 7 is connected with the drain pipe 4, and a booster valve 10 is provided at the connection with the drain pipe 4. The liquid outlet is designed at the top of the cyclone 7, which is beneficial to the discharge of sewage and the collection of sand.
[0024] A second filter screen 11 is provided at the upper inner part of the cyclone 7, and a sand discharge pipe 12 is provided at the bottom end of the cyclone 7. The second filter screen 11 is used to block the sand again to prevent it from flowing out with the water flow, causing waste of sand and increasing the workload of the sewage treatment unit 1.
