The invention discloses a dustproof static-electricity-removing heat dissipation device for a television. A machine body is included, and a dust collection device is arranged in the machine body; a dust collection fan is arranged in the dust collection device; and a static electricity removing device and a heat dissipation device are further arranged on a lower side of the dust collection device.In the invention, the dust collection device is arranged; dust in the television is treated; excessive dust in the television is prevented and an influence on normal operation is avoided; the static electricity removing device is arranged on the lower side of the dust collection device so that static electricity in a case is adsorbed and utilized, and a situation that internal components are damaged and inconvenient to maintain due to excessive static electricity in the television is avoided; and the heat dissipation device is arranged on the lower side of the static electricity removing device, the adsorbed static electricity is converted into electric energy to carry out heat dissipation treatment on the television so that the television works more smoothly, and the device is high in automation degree, convenient to use and rapid.

The invention discloses a large mining excavator and a cable drum device of the large mining excavator. The cable drum device comprises a drum, a support, a motor driving device, a cable arranging mechanism, a top cover and a high-pressure sliding ring device, wherein the drum is used for enabling a cable to be wound and unwound, the drum is provided with a drum shaft, an end portion of the drum shaft is provided with a connecting bolt, the two ends of the drum are fixed to the support, the motor driving device is used for driving the drum to rotate, the cable arranging mechanism is used for enabling the cable to be evenly and orderly wound onto the drum and unwound from the drum, the ratio of the running speed of the cable arranging mechanism, the rotating speed of the drum and the speed of a walking mechanism of the excavator is kept constant, the top cover is arranged on the top of the drum, the high-pressure sling ring device is provided with an integral type box body, an upper bearing and a lower bearing are arranged at the upper portion of the box body and the lower portion of the box body respectively, and the shaft end, in the position of the upper bearing, of the high-pressure sliding ring device is provided with a long circular hole so that the shaft end can be inserted onto the connecting bolt when the high-pressure sliding ring device is installed. According to the large mining excavator and the cable drum device of the large mining excavator, the performance and the safety of the large mining excavator are improved, and use cost is reduced.

The invention relates to a landfill percolate treatment novel process method, which comprises the following steps: (1) collecting and gathering the landfill percolate into a regulating tank; (2) lifting the outlet water of the regulating tank to enter an ammonia stripping reaction vessel; (3) carrying out coagulating sedimentation treatment on the landfill percolate after ammonia stripping; (4) making the outlet water of the coagulating sedimentation enter an anaerobic reaction vessel for carrying out anaerobic treatment; (5) sequentially making the outlet water of the anaerobic reaction vessel enter an anoxic tank, an aerobic tank and an MBR reaction tank, wherein mixed liquid carries out back flowing from the MBR reaction tank to the anoxic tank, a membrane assembly used in the MBR reaction vessel is a flat plate MBR film assembly, and the MBR has the form of the submerging form; and (6) making the outlet water of the MBR reaction tank enter a reverse osmosis system, directly discharging the treated outlet water, and making reverse osmosis concentrated solution flow back to the regulating tank. The invention aims at the water quality features of the landfill percolate, reasonably combines the physicochemical treatment and biological treatment unit, and has the advantages of short and compact process flow, high treatment efficiency, low energy consumption, long service life of the membrane assembly and the like.

A brake subpump adjuster with a pressure-relief valve comprises a cylinder, a lever, a push rod, an intake valve and a pressure-relief valve. The cylinder has first and second ends and at the first end is disposed a fixed piece. One end of the lever is set at the second end of the cylinder and the other end has a joint. The push-rod movable passes through the cylinder and the handle. At one end of the push-rod is disposed a support piece to press the subpump and at the other end is disposed a handle to rotate the push-rod. The intake valve is disposed on one side of the lever to make the piston move, so as to make the push-rod shift. The pressure-relief valve is set on the other side of the lever for relasing high-pressure gas from the cylinder to pull back the push-rod to the initial position.

The invention provides a clamping mechanism for loading and unloading silicon rods, which includes a magnet fixing seat, a step-shaped through hole is opened in the center of the magnet fixing seat, and a copper column is elastically connected to the through hole through a spring, and the electromagnet is fixed on the magnet. On the seat, a sliding column is fitted through the gap of the electromagnet, and an iron block is fixed at one end of the sliding column close to the electromagnet. A clamping mechanism for loading and unloading silicon rods according to the present invention, this kind of clamping method is firm and reliable, and the silicon rods are further clamped, and the effect is better. The use of this clamping mechanism can further tighten the silicon rods. Clamping and fixing improves the safety factor during the transfer of silicon rods, and the operation is realized by turning on and off the power, which reduces the number of mechanical maintenance and improves the service life.
