Background
A large amount of fine coal slag, coal dust, molten metal and other small solid particles are entrained in wastewater generated by a coal chemical device, an organic flocculant PAM and an inorganic flocculant PAC are required to be added for sedimentation separation, and after a certain concentration is reached, the wastewater is pumped to a subsequent vacuum filter through a secondary slurry pump to drain water to become a filter cake, the filter cake can be recycled and utilized, and meanwhile, the environment pollution caused by the wastewater is avoided to the greatest extent. However, due to the sticky and easy-to-deposit properties of the slurry, in the wastewater sedimentation process, particularly in a slurry storage tank, if the operation interval of operators is too long, the slurry is not delivered timely, so that a large amount of solid in the slurry at the bottom of the slurry storage tank is accumulated, the inlet pipe of a secondary slurry pump is blocked, deposited sludge is bridged at the bottom, even an agitator is damaged due to overflow, and meanwhile, the load of a vacuum filter is greatly fluctuated to damage.
Disclosure of Invention
The utility model provides a solid-containing sewage conveying device for coal chemical industry, which aims to solve the problems that the operation interval time of personnel is too long and the slurry is not delivered timely in the wastewater sedimentation process.
The utility model provides a coal industry contains solid sewage conveyor which characterized in that the device includes first thick liquid pump, second thick liquid pump, vacuum filter, thick liquid storage tank and clarification tank, the pipeline that the clarification tank was put into respectively to coal cinder thick liquid and mud, the clarification tank export is linked together to thick liquid storage tank import through first thick liquid pump, thick liquid storage tank export pipeline sets up the second thick liquid pump, divide into circulation pipeline and delivery line after this pipeline passes through the second thick liquid pump, circulation pipeline returns to thick liquid storage tank through the circulation valve, delivery line is linked together to the vacuum filter entry after the delivery valve;
the device also comprises a cleaning pipeline, the cleaning pipeline is divided into two paths, the first path of cleaning pipeline is communicated with the circulating pipeline through a first flushing water valve, and the communicated position is positioned behind the circulating valve; the second cleaning pipeline is communicated to the delivery pipeline through a second flushing water valve, and the communicated position is positioned behind the feeding valve.
A first stirrer is arranged in the clarifying tank.
A second stirrer is arranged in the slurry storage tank.
The utility model has the beneficial effects that: the device has replaced frequent manual operation, effectively avoids thick liquid deposition bridging of thick liquid storage tank bottom to block up, effectively solves the pipeline and blocks up the problem, can stabilize outer pay-off for a long time moreover. The device has convenient operation, advantage that control effect is good, and bridging and the frequent jam of thick liquid pump import and export pipeline of preliminary water treatment unit thick liquid storage tank are solved effectively, and the frequency is reduced in the vacuum filter cloth change, and filtrate quality of water is good, has practiced thrift manpower financial resources.
