The utility model discloses a series excited motor convenient to replace a carbon brush, comprising a housing, one end of the housing is provided with an installation assembly, the inner wall of an installation end cover is provided with an auxiliary assembly, through the installation assembly arranged on the housing, the carbon brush can be replaced without the help of a plurality of tools for long-time disassembly and assembly, and the replacement efficiency is improved. Compared with the prior art, time and labor cost required for replacing the carbon brush are greatly shortened, production stagnation or equipment idle time caused by carbon brush replacement is shortened, flexibility and timeliness of equipment maintenance are improved, meanwhile, an auxiliary assembly is arranged on the installation end cover, the carbon brush can be conveniently and rapidly disassembled and replaced, and the service life of the carbon brush is prolonged. The surface of the carbon brush and the surface of the commutator can be cleaned in real time, impurities such as powder attached to the surfaces of the carbon brush and the commutator are effectively removed, good contact between the carbon brush and the commutator is ensured, stable conductivity is maintained, and the surface of the commutator is flexibly cleaned; and the risks of poor conductivity, motor performance reduction and even damage caused by impurity accumulation are reduced.

The invention relates to the technical field of hydraulic pump stations, and discloses a hydraulic pump station with a pressure protection structure and a protection method thereof.The hydraulic pump station comprises a hydraulic pump station body, a jack is placed on the side wall of the hydraulic pump station body, and a male head is fixedly connected to the side wall of a second threaded pipe. A pressure mechanism is arranged in the equipment, when a sliding pipe slides towards a first threaded pipe, hydraulic oil located in a slope through hole flows into a circulating hole and fills the inner space of the circulating hole, then a worker loosens the sliding pipe, the circulating hole coincides with a flowing groove again, and then the hydraulic oil flows into the circulating hole to be recycled. The hydraulic oil in the circulation hole is discharged outwards through the sliding pipe, and finally the hydraulic oil is accumulated in the position of the annular groove, so that when the female head and the male head are spliced, the hydraulic oil accumulated in the female head is preferentially discharged out of gas in the female head, and the situation that the hydraulic oil is driven to synchronously flow when follow-up liquid flows is prevented.

The utility model discloses a spray drying filter screen anti-accumulation device for concrete water reducing agent production, which relates to the technical field of concrete water reducing agent production equipment and comprises a box body, an atomization component is mounted on one side of the box body, a high-temperature pipeline component is arranged on the other side of the box body, and a blowing component is arranged below the high-temperature pipeline component. A top cover is arranged at the top end of the box body, a lifting mechanism is arranged at the upper end of the top cover, a support is connected to the lifting mechanism, the lower end of the support extends into the box body and is connected with an obliquely-arranged filter screen plate, and an exhaust hole is formed in the top of one side of the box body. According to the utility model, the electromagnetic valve is periodically opened, so that compressed air in an external air compressor instantly enters the box body from the shunting blowing pipe to blow off water reducing agent powder particles attached to the filter screen plate, and the height of the filter screen plate is continuously adjusted, so that the water reducing agent powder particles are prevented from being accumulated on the filter screen plate; the subsequent atomized water reducing agent can be effectively attached to the filter screen plate, and the production effect of the water reducing agent is improved.

The application discloses a kind of ore pulp stirring leaching tank equipment, including cathode leaching tank and anode leaching tank, middle tank is arranged between cathode leaching tank and anode leaching tank;Cathode leaching tank is separated by first membrane assembly between cathode leaching tank and middle tank;Anode leaching tank is separated by second membrane assembly between anode leaching tank and middle tank;Filter cloth is arranged between second membrane assembly and anode leaching tank;Cathode electrolytic column is arranged in cathode leaching tank;Anode electrolytic plate and agitator are arranged in anode leaching tank;Anode leaching tank is cylindrical, and its bottom end is provided with conical bottom;Anode electrolytic plate is annular, and is coaxially arranged with anode leaching tank, and agitator is located at the annular center position of anode electrolytic plate.The middle tank is arranged between cathode leaching tank and anode leaching tank, and forms a filter cloth double-membrane three-tank structure with first membrane assembly, second diaphragm assembly and filter cloth;Meanwhile, the conical bottom can make the ore pulp at the bottom of anode leaching tank gather to the center of conical bottom, so that the ore pulp can be fully stirred.
