Description
Technical field
The utility model relates to a kind of brine pump water blocking device, especially relate to a kind of at forced pumping plant the brine pump maintenance or during cleaning water pump salt crust, the device that the water intake of water pump is blocked.
Background technique
The main task of salt lake bittern exploitation is to adopt halogen and defeated halogen.Because bittern is the salt solution that high concentration contains the number of chemical component, wherein one or more salinities reach capacity, so in adopting halogen or defeated halogen process, the mobile and stirring of saturated bittern can make adopts defeated halogen equipment and generation corrosion of bittern contact position and salt crust; Again owing to the temperature variation of bittern or the mobile and stirring of adopting saturated bittern in the defeated halogen process, having young partial crystallization goes out and is attached to the surface that equipment contacts with bittern, crystal constantly growth can further cause the serious salt crust of equipment and reduce effect, in addition can make adopt, defeated halogen work can not move.
In the exploitation of the salt lake of China, the method for trying out many anti-salt crusts is as the anti-salt crust method of chemistry, ultrasound, static, magnetic force method etc.Because the inhibitor of the anti-salt crust method of chemistry costs an arm and a leg, and contains certain toxicity, therefore use and be subjected to certain restriction.And ultrasound, static, magnetic force method be because of the equipment complexity, and power consumption is adopted more greatly and seldom.Adopt of producer adds the method that fresh water prevents salt crust more both at home and abroad at present, and this method has advantages such as cost is low, and manufacturing equipment is simple.Having under the situation of more abundant outside fresh water, can adopt face of land fresh water pipeline will be with pressure fresh water to be added in the water pump or and be added to water pump suction port place by pipeline and injection point, utilize the suction negative pressure of water pump to mix suction, owing to bittern is watered down, so in adopting defeated halogen equipment, can prevent salt crust; The shortcoming of this method is that construction investment is big, and the fresh water of consumption is many, the cost of production height.Under the situation of no outside fresh water, can adopt tank car to transport fresh water, but the clear salt of immersion after fresh water can only quit work as water pump in the water tank can not prevent salt crust, and soak time is longer to water tank, clear salt workload is big, and the reserve position number of brine pump is more.And water pump is prevented that the method for water passage surface crystallization from adopting phenolic sand molding more, reducing roughness, and methods such as overcurrent position plastic-blasting, the shortcoming of the method is the time that can only alleviate salt crust, can not solve the problem of salt crust up hill and dale.
Chinese patent ZL200620051237.3 number a kind of brine pump lifting device is disclosed, use crane gear brine pump to be sling by lift pot, be put in the clear water reserviors on pumping plant next door, the cleaning salt crust, because lift pot is heavier, post and beam, crane gear etc. to the pumping plant factory building are had relatively high expectations, and construction investment is corresponding also can be increased to some extent.
The model utility content
The purpose of this utility model is to overcome the defective that the clear salt technology of existing anti-salt crust exists, provide a kind of and needn't lay outside water supply line, can effectively save construction investment, clear salt workload is little, the salt lake bittern exploitation brine pump water blocking device that equipment sparing platform number is few.
The purpose of this utility model is achieved through the following technical solutions: it comprises water blocking device, lifting structure, fluid pressure drive device; Described water blocking device is made of base plate, flexible plug, lifting bar, water string, connecting rod and Sealing, described flexible plug is fixed on the base plate middle part, its size and brine pump water intake size adapt, one of lifting bar is installed on the base plate, and the other end is hinged by water string and fastening piece and Sealing and connecting rod one end; The other end of connecting rod is connected with lifting structure, and lifting structure is connected with fluid pressure drive device.
The preferred triangle crown type of the shape of described flexible plug because of the crown flexible plug of triangle can be made adaptive change with the shape of pump intake salt crust, thereby can be blocked water intake more effectively.
Described flexible plug can be the plug that each type flexible material such as rubber plug, rubber and plastic plug or engineering plastics plug are made.
Water string is embedded in the concrete of pumping plant platform, and water blocking device is installed on the pumping plant platform by water string, and lifting structure and fluid pressure drive device can be arranged in the casing, are placed on the pumping plant platform.
The import and export pipeline of brine pump needn't be adorned valve, and the water intake of water pump should be placed on below the concentraing pond lowest water level.
After brine pump moves a period of time, the pump chamber salt crust, the bittern flow reduces to a certain degree, and water pump quits work, and the lifting bar of water blocking device rises under the driving of hydraulic pressure installation by connecting rod and lifting structure, and the water intake of water pump is blocked; Then the adpting flange of pumping line and external pipe is taken apart, with crane gear brine pump (containing motor) is sling, be put in the clear water reserviors on pumping plant next door, turn on pump stirs, the cleaning salt crust.
The utility model is simple in structure, and manufacturing expense is lower; Than Chinese patent ZL200620051237.3 number disclosed brine pump lifting device, removed the weight of lift pot, make the post of pumping plant factory building and construction investments such as beam, crane gear reduce; Outside water supply line be needn't lay, investment and cost of management saved for cleaning salt crust tubing; Cleaning behind the brine pump salt crust, simple to operate, the efficient height; Fresh water consumption is few, helps protecting water resources, the protection environment.
