Description

Technical Field

[0001] The utility model belongs to the technical field of concrete production, and particularly relates to a device for recycling and reusing wastewater in concrete production. Background Technique

[0002] With the booming development of the modern construction industry, concrete production has become an important cornerstone to support the continuous progress of this industry. However, during the concrete production process, a large amount of wastewater is inevitably generated. If this wastewater is directly discharged without effective treatment, it will not only lead to the waste of precious water resources, but may also cause serious pollution to the environment, threatening the ecological balance and human health. To address this challenge, the industry generally uses devices for recycling and reusing wastewater in concrete production to treat the wastewater, aiming to achieve the dual goals of water resource recycling and environmental protection. However, in the actual application process, existing devices for recycling and reusing wastewater in concrete production have a series of problems.

[0003] Firstly, existing devices for recycling and reusing wastewater in concrete production often lack the function of primary filtration of wastewater. Before the wastewater enters the treatment system, large particle impurities such as sand and gravel are not effectively removed, which not only affects the efficiency of subsequent treatment processes, but may also damage the equipment; secondly, existing devices for recycling and reusing wastewater in concrete production lack an effective control mechanism when discharging the liquid after sedimentation is completed. During the discharge process, it is easy to re-introduce the already sedimented solid substances into the liquid, resulting in a decline in treatment effect and even possible secondary pollution; finally, existing devices for recycling and reusing wastewater in concrete production have difficulties in cleaning the sedimentation chamber. Since a large amount of sediment often accumulates in the sedimentation chamber and it is difficult to clean it by simple means, this not only increases the difficulty of cleaning work, but may also affect the normal operation of the equipment.

[0004] Therefore, it is very necessary to invent a device for recycling and reusing wastewater in concrete production. Content of the Utility Model

[0005] The purpose of the utility model is to provide a device for recycling and reusing wastewater in concrete production to solve the problems mentioned in the background technique.

[0006] To solve the above technical problems, the utility model is realized through the following technical solutions:

[0007] The utility model relates to a device for recycling concrete production wastewater, which comprises a box body, a liquid storage cavity, a sedimentation cavity, a water diversion plate, a primary filter rack, a slag discharge pipe, a lifting plate, an electric push rod, a drain pipe, a slag collection box and a flushing rack. The box body is fixed on the ground through expansion bolts, and a liquid storage cavity and a sedimentation cavity are respectively arranged inside the box body. A water diversion plate is arranged between the liquid storage cavity and the sedimentation cavity, and the outer edge of the water diversion plate is fixed to the inner wall of the box body by welding; A primary filter rack is fixed on the upper side of the box body through bolts, and the output end of the primary filter rack is communicated with the sedimentation cavity; A slag discharge pipe is fixed on one side of the box body by welding, and the inside of the slag discharge pipe is communicated with the inside of the sedimentation cavity; A lifting plate is slidably installed inside the slag discharge pipe, and the upper end of the lifting plate is fixed to the output end of the electric push rod through bolts, and the electric push rod is fixed to the slag discharge pipe through bolts; A drain pipe is fixed to the other side of the box body through a joint, and the inside of the drain pipe is communicated with the liquid storage cavity; A flushing rack is fixed inside the liquid storage cavity through bolts, and the output end of the flushing rack is arranged inside the sedimentation cavity; A slag collection box is fixed on the outer side of the box body through bolts.

After the concrete production wastewater is completely sedimented inside the sedimentation cavity, the corresponding electromagnetic valves can be opened according to the height of the sediment inside the sedimentation cavity, so as to guide the water inside the sedimentation cavity into the liquid storage cavity, thereby preventing the sediment from entering the liquid storage cavity.

[0009] Furthermore, the primary filter rack includes a housing, a water inlet, a roller, a filter belt, a cleaning shaft, and a slag discharge pipe.
