Residual slurry pumping device

Abstract

The invention provides a residual slurry pumping device. The residual slurry pumping device comprises a residual slurry barrel, a pumping hopper, an air cylinder and a control cabinet, wherein a feeding hole is formed in the bottom of the residual slurry barrel; the residual slurry barrel is communicated with the pumping hopper by virtue of the feeding hole; a sealed door is arranged under the feeding hole and is connected with a piston rod of the air cylinder; an air discharging hole and a first air charging hole are formed in the top of the pumping hopper; an air discharging valve is arranged at the air discharging hole; a first air charging hole is formed in the first air charging hole; a discharging hole is formed in the bottom of the pumping hopper and is connected with a discharging pipe; a second air charging hole is formed in the head end of the discharging pipe; a second air charging valve is arranged at the second air charging hole; the first air charging hole and the second air charging hole are connected with an air source; the cylinder, the air discharging valve, the first air charging valve and the second air charging valve are electrically connected with the control cabinet. The residual slurry pumping device can be used for conveying residual slurry in the residual slurry barrel to a mixing plant of a construction site, so that the problem of the pollution to the environment caused by overflow of the residual slurry on the construction site can be avoided; meanwhile, the waste of resources can be also be avoided.

Description

【Technical field】 [0001] The invention belongs to an auxiliary equipment structure for building construction, in particular to a residual slurry extractor. 【Background technique】 [0002] In the field of construction, after the concrete pipe pile is formed, there is residual slurry on the inner wall of the pipe pile after high-speed centrifugal rotation and compression. For the treatment of this residual slurry, currently it is generally hoisted and then poured into the residual slurry bucket, and then the sewage pump is used. The residual pulp in the residual pulp barrel is pumped to the waste pile. Due to the characteristics of the residual pulp, the sewage pump is prone to failure in the process of pumping the residual pulp, resulting in the overflow of residual pulp at the job site, resulting in poor operating environment. Even if the work is arranged Personnel cleaning is also not clean, which not only consumes labor and time costs, but also causes a waste of resources....

AI Technical Summary

Problems solved by technology

[0002] In the field of building construction, after the concrete pipe pile is formed, the inner wall of the pile after high-speed centrifugal rotation and compression has residual slurry. Currently, the treatment of the residual slurry is generally carried out by lifting it with a crane and pouring it into the residual slurry bucket, and then using a sewage pump. Pump the residual slurry in the residual slurry tank to the waste pile, and due to the characteristics of the residual slurry, the sewage pump is prone to failure during the process of pumping the residual slurry, resulting in the overflow of the residual slurry on the job site, resulting in poor sanitation of the working environment, even if the work is arranged Personnel cleaning is also not clean, which not only consumes labor and time costs, but also causes a waste of resources
