Description

Vertical water is isolated the water storage device that send of slurry conveyer

The utility model relates to the water storage device that send that a kind of water comes convey materials, and a kind of vertical water of more specifically saying so is isolated the water storage device that send of slurry conveyer.

Vertical water is isolated the slurry conveyer and is widely used in industries such as mine, ferrous and nonferrous metals, power plant, aluminium manufacturer, coal chemical industry, building materials, carry media such as mine tailing, concentrate, mud, bauxite, red mud, mortar, coal water slurry, the water storage device that send wherein is the important component part that vertical water is isolated the slurry conveyer, but because structure is not too reasonable, the fluctuation of current cause is bigger, water pump is produced bigger impact, make its parts impaired, have a strong impact on service life.

The purpose of this utility model is, provides a kind of rational in infrastructure, reduces or eliminate the fluctuation back and forth of water supply current, and then reduces or eliminate current are isolated the slurry conveyer to the vertical water of water pump impulsive force the water storage device that send.

The purpose of this utility model reaches by the following technical programs.This vertical water is isolated the water storage device that send of slurry conveyer, by water pump 1, the sealing chamber 4 that links to each other with this water pump by coolant inlet pipe 7 and water valve 2, be positioned at the ball float 3 of this sealing chamber, return water pipe 5, non-return valve 10, pulp-inlet pipe 11 and grout outlet 9 are formed, its special character is to establish the buffer air jar 6 that communicates with them once connection pipe between water pump 1 and water valve 2.

The structure of buffer air jar can adopt existing air pressure jar, as air sac air holder, air bellow, metal or plastics formula air holder, also can design as required.Its basic structure is: it has a tank body, is positioned at the water inlet pipe and water outlet pipe of tank base, is positioned at the intake and exhaust device at tank body top and can detects what pressure detection read out instrument of air, so that can be in time to air holder aerating or exhaust.

Because the utility model is provided with the buffer air jar between water pump 1 and water valve 2, make it compared with prior art, this buffer air jar is the instantaneous deficiency that supplies water of discharge water and make-up pump as required, sucks water as required, thereby has reduced the fluctuation back and forth of water inlet in-pipe flow.Reduced the impact of current to water pump thus, prolonged the service life of water pump, making here becomes possibility with centrifugal pump.

The explanation of accompanying drawing drawing

Fig. 1-a kind of structural representation of the present utility model

The vertical water that send water storage device that Fig. 2-contain is shown in Figure 1 is isolated the structural representation of slurry conveyer

Provide embodiment of the present utility model below in conjunction with accompanying drawing, be used for further specifying technical solution.

Embodiment 1, with reference to figure 1, Fig. 2.Annexation between water pump 1, buffer air jar 6, water valve 2, sealing chamber 4, ball float 3, return water pipe 5, non-return valve 10, pulp-inlet pipe 11 and the grout outlet 9 as shown in Figure 1.The buffer air jar is a kind of air holder of the prior art, and sealing chamber 4 is 3, and water valve 2 corresponding with it, ball float 3 also are 3.The right at Fig. 1 increases a water storage container 8, and the water outlet of return water pipe 5 is communicated with it, and the water outlet of water storage container 8 communicates with water pump 1; Left end at Fig. 1 increases an ore pulp feeder 12 again, has just formed vertical water shown in Figure 2 and has isolated the slurry conveyer.Isolate the slurry conveyer below in conjunction with vertical water shown in Figure 2 working process of the present utility model is described.Principle of work is: suppose that at first this conveyer is in a certain moment of normal operation, the slurry of a sealing chamber in left side is filled, is in the plasma discharge state for the treatment of, middle sealing chamber is in into pulpous state attitude, and the sealing chamber on right side is in the plasma discharge state.The advancing of water valve 2 on the sealing chamber of this moment left side, backwater valve all are in closed condition, and the flood valve of intermediate isolating jar water valve 2 is closed, and backwater valve is opened.The flood valve of right side sealing chamber water valve 2 is in open mode, and backwater valve is in closed condition, and the internal pressure of the buffer air jar 6 of contain air is identical with water pump 1.Now open the flood valve of left side sealing chamber water valve 2, in the moment that water valve 2 is opened, the hydraulic pressure in the coolant inlet pipe obtains suddenly discharging, and pressure reduces, and water velocity is accelerated; Because water pump drain water amount is certain, cause flow velocity certain, can not satisfy the demand of sealing chamber to water, the trend that forms meiobar is arranged in coolant inlet pipe, but at this moment the high pressure water in the buffer air jar 6 is just discharged rapidly, enter the left side sealing chamber through coolant inlet pipe 7, both satisfied the demand of sealing chamber to water, avoided the formation of meiobar in the coolant inlet pipe again, it is excessive to prevent that this conveyor system pressure from reducing, water in coolant inlet pipe refluence and back and forth the fluctuation (water is in the fluctuation back and forth of water pipe, be commonly called as water hammer), and then make pump operation speed slack-off, the generation of stall or reversal development has kept the normal of the normal operation of water pump and hydraulic pressure, prevented the water pump water wheels, rotating shaft, the damage of motor etc., prolonged service life, made water pump become possibility, greatly reduced cost and energy consumption with centrifugal water pump.Along with increasing of supplying water in the sealing chamber of left side, system pressure increases gradually, and the buffer air jar forwards to by water pump 1 to its moisturizing, until reaching the system pressure balance also by outside draining.When left side sealing chamber plasma discharge finishes, the flood valve of its water valve 2 is closed, in the moment that flood valve 2 is closed suddenly, the Shuitu of coolant inlet pipe so is subjected to big resistance, and water has refluence trend, and the buffer air jar has water to enter again, shunt part hydraulic pressure, eliminated or reduced the refluence of water.Left side sealing chamber water valve 2 backwater valves are opened, and the pressured difference of the slurry of feeder 12 is opened the slurry-inlet valve of non-return valve 10, and slurry pushes away ball float 3 on the slurries in pulp-inlet pipe 11 enters this sealing chamber, and ball float 3 makes waterborne moving through return water pipe 5 get back to water storage container 8.Centre, right side sealing chamber advance, the plasma discharge principle is same as described above.Three jars hocket into slurry, plasma discharge reach the purpose of continuous plasma discharge.The draining and the water inlet process of buffer air jar will repeat above process later on, and role is identical.In a word,, reduce or prevented the generation of water hammer, guaranteed the normal operation of water pump, prolonged service life, make vertical water isolate the slurry conveyer and can use centrifugal pump just because of the effect of buffer air jar.

In like manner, can also provide sealing chamber is 2,4,5, and other parts structure unmodified embodiment.
