According to the smashing and washing device for waste plastic recycling, the problem that a sewer is blocked can be solved through a spraying devicewith circulated filtration, dirt can be removed conveniently, water resources can be utilized repeatedly, the cost is reduced, a reaming breaking box and the collection box can carry out polishing after reaming breaking, a smashing device is not blocked, the smashing efficiency is improved, the service life of the device is prolonged, waste plastic can be retrieved and washed by the conveyer beltwith the groove belt, and the efficiency of washing and the efficiency of smashing of the device are improved.

The invention provides an environment-friendly bamboo rat breeding device specific to breeding dead angle cleaning of bamboo rats. The breeding device comprises a device body, a feces cleaning device,a partition plate and a filtration collector, feces can move upwards along a bevel edge by enabling the feces to be conducted by a cleaning rod in the cleaning process through the active connection of a rotating wheel, the problem that the feces are accumulated and thus are difficult to clean is completely eradicated, a better cleaning effect is achieved, by arranging a rotor, water flows out ofa water outlet slowly to dilute accumulated feces, the feces are better cleaned and recycled, meanwhile, a large quantity of accumulated water appearing in the breeding device is further avoided in the cleaning process, dryness in the breeding device is maintained, by arranging a cleaning surface of which the shape is of an externally expanded arc, the cleaning area of a dead angle is increased, meanwhile, a cleaning solution extrusion ejector is arranged in the middle of the cleaning surface of the dead angle, inward extruding force can be brought about to extrude a cleaning solution out to be sprayed on the cleaning surface when the cleaning surface cleans, and the dead angle can be better cleaned.

The invention relates to the technical field of environment protection equipment, and discloses a water tank water resource recycling device, which comprises a first water tank. A filter screen is movably connected to the bottom of the inner wall of the first water tank, a filter chamber is fixedly connected to the bottom of the side face of the first water tank through a water guiding pipe, a filter element is clamped into the filter chamber, a water suction pump is fixedly connected to one side of the filter chamber through a water suction pipe, a water outlet pipe is fixedly connected to the top of the water suction pump, and the end, away from the water suction pump, of the water outlet pipe extends into a second water tank and is movably connected with the second water tank. The filter screen is used for filtering fish scales and impurities in the first water tank, the filter element is used for purifying and filtering water discharged from the first water tank so that water withthe water quality can be secondarily used, the purified water is guided into the second water tank to be collected for standby use through the water suction pump, the advantage of cleaning and recycling water discharged from the water tanks conveniently is achieved, and the problem of waste of a large amount of water resources due to direct discharging of water in the water tanks is solved.

The invention provides a method for treating silicon in waste oil sand which is generated in a silicon ingot cutting process. The method comprises the following steps of: washing the waste oil sand in alkali liquor for a certain period of time in a countercurrent mode to dissolve silicon powder, a small amount of iron, copper and residual polyethylene glycol (PEG) in the waste oil sand; separating the mixture to obtain waste oil sand solid and liquid which is obtained after washing; adding alkali into the liquid which is obtained after washing till the solution reaches a certain concentration; washing the waste oil sand once again; repeating the steps of adding the alkali and washing the waste oil sand for several times; washing the waste oil sand by using pure water; separating to obtain silicon carbide (SiC) solid and liquid which is obtained after washing; drying the SiC, and recycling; adding the alkali into the liquid which is obtained after washing to obtain a washing solution for washing other waste oil sand; and when the concentration of the silicon in the liquid which is obtained after washing reaches the needed concentration, collecting, and thus obtaining silica sol. In the whole treatment process, materials are recycled in a closed mode, and the method is pollution-free, environment-friendly (waste water cannot be generated and discharged), low in consumption and economic. By the method, the defects of complex process flows, low efficiency, high energy consumption, long treatment cycle, severe environmental pollution and the like which commonly exist in the prior art of recycling the silicon are overcome, and the problems of the accumulation of waste residues and environmental pollution in industries are solved effectively.
