Description

Technical Field

[0001] The utility model relates to the field of sand washing equipment, in particular to a sand and gravel production sewage treatment system. Background Art

[0002] Sand washing means that if you just use water to wash the mud and sand, the wastewater produced does not contain other chemical raw materials. Such wastewater can be recycled again after sedimentation to remove the solid components. If sand washing is done by chemical washing, the chemical components in the wastewater need to be neutralized by adding other chemical raw materials, at least to make the wastewater non-toxic and without causing secondary hazards, so that it can be discharged normally. Wastewater treatment requires sedimentation tanks, reaction tanks, and toxicity tests before it can be discharged or continued to be used.

[0003] The existing sand washing sewage sludge discharge equipment is overall large and costly. The general sand washing sewage sludge discharge method is to manually pour the sewage and sand washing agent into a designated container for mixing. This sludge discharge method has low working efficiency and requires manual continuous stirring of the sewage during the reaction to speed up the reaction between the sand washing agent and the sewage, which requires a lot of manpower.

[0004] In view of the above reasons, a sand and gravel production wastewater treatment system has been developed. Utility Model Content

[0005] The purpose of the utility model is to overcome the deficiencies in the prior art and provide a sand and gravel production wastewater treatment system to reduce the difficulty and cost of wastewater treatment. The treated water can be recycled, which greatly reduces the production cost. All water is in an internal closed-loop circulation, and no wastewater flows out, and there is no wastewater pollution to the environment. The mud and sand in the sedimentation tank are easy to clean, saving time and effort, and greatly reducing the waste of labor.

[0006] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a sand and gravel production wastewater treatment system, including a sedimentation tank and a purification tank, the front and rear ends of the sedimentation tank are respectively provided with a water inlet and an overflow port, the overflow port of the sedimentation tank is connected with the purification tank through a pipeline, a lifting frame is arranged on the rear end of the sedimentation tank, the lifting frame is connected with a lifting bucket through a wire rope, the lifting bucket can penetrate into the sedimentation tank, and an inclined plate is arranged in the sedimentation tank.

[0007] Furthermore, the lower end of the inclined plate is flush with or higher than the upper end surface of the lifting bucket.

[0008] Furthermore, a pair of brackets are arranged on both sides of the lower end of the inclined plate, the lower end of the inclined plate is hinged to the brackets accordingly, a lifting motor is arranged at the front end of the sedimentation tank, a lifting wheel is arranged on the output shaft of the lifting motor, and the lifting wheel is connected to the front end of the inclined plate by a steel wire rope.

[0009] Furthermore, a filter layer is arranged in the purification pool, and a drain outlet is arranged at the lower end of the purification pool.

[0010] Furthermore, the filter layer is filled with filter sand.

[0011] Furthermore, a filter screen is provided at the overflow port of the sedimentation tank.

[0012] The beneficial effects of the utility model are as follows: sand washing sewage enters the sedimentation tank through a pipeline, and the mud and sand debris in the sewage fall into the inclined plate or the lifting bucket after sedimentation, and the water in the sedimentation tank flows into the purification tank through the overflow port, and the water in the purification tank is filtered by the filter layer and then transported to the sand washing equipment by a water pump for reuse; when the sedimentation tank needs to be cleaned, the water in the sedimentation tank is first discharged, and the lifting motor is started, the lifting motor drives the upper end of the inclined plate to rise upward, and the mud and sand debris on the inclined plate falls into the lifting bucket, the inclined plate returns to its original position, and the lifting bucket is raised to clear out the mud and sand debris; the utility model reduces the difficulty and cost of sewage treatment, and the treated water can be recycled, which greatly reduces the production cost; all water is in an internal closed-loop circulation, no sewage flows out, and no sewage pollutes the environment; the mud and sand debris in the sedimentation tank is easy to clean, which saves time and effort, and greatly reduces the waste of labor; the parts not introduced in detail in the utility model are existing common technologies.
