Description
Technical field
The utility model relates to a kind of filter press feed arrangement, is serially connected between filter press and pan feeding pump.
Background technology
Traditional filter press operationally, completely by a direct people's material of pan feeding pump also extrusion dehydration, until coal slime dewatering completes, such pan feeding pump expects people the unstable working state being just in low discharge, high pressure after the stage completes, often cause pump and motor damages, add the maintenance capacity of equipment, waste a large amount of man power and materials, so that have influence on normal coal washing production.Therefore, need the enter material way improving filter press further badly, reduce accident rate.
And the operating characteristic of pan feeding pump when expecting to filter press people is that flow is from 300m
3/ h reduces gradually, pressure is 0.38MPa, after about 15min filter press enter water of compaction stage by stage after, the flow of pump reduces to zero gradually, pressure then rises to 0.5MPa, keep the about 15min of this state, the most moisture in coal slime are extruded away completely, and filter press completes a working cycles of slime water treatment.Pump works under the state of high pressure, low discharge, has increased the weight of the wearing and tearing of the impeller of pump, spiral case and accessory impeller, also easily makes motor damage because of overload operation, leads to Electromechanical Accidents.In order to both reduce the wearing and tearing of the impeller of pump, spiral case and accessory impeller, reduce the probability of motor damages, do not affect again filter press normally to work, complete slime water treatment task, applicant utilizes existing 0.6MPa high-pressure blast in factory to help pan feeding pump to filter press charging.So both can reduce the duration of runs of pan feeding pump, allow the wearing and tearing of pump and motor discontinuous running, further reduction equipment, and the feed pressure of the pressure ratio pump of high-pressure blast is higher, the dewatering efficiency of filter press can be improved, shorten the cycle period of filter press work.
Utility model content
The purpose of this utility model overcomes the problems referred to above existing in prior art, and provide a kind of filter press feed arrangement of reasonable in design.
The utility model solves the problems of the technologies described above adopted technical scheme: this filter press feed arrangement, it is characterized in that, comprise balancing gate pit, air injection pipe, air-supply valve, venting valve, electro connecting pressure gauge, material inlet valve, pan feeding valve, pan feeding pump and filter press, the top of described balancing gate pit is provided with air injection pipe, the rear of air injection pipe is provided with air-supply valve, air injection pipe stage casing is provided with venting valve, described balancing gate pit is provided with electro connecting pressure gauge, the top of side, described balancing gate pit is connected with pan feeding pump by material inlet valve, bottom is connected with filter press by pan feeding valve, the import of described air injection pipe is provided with non-woven filter cloth filter screen.
As preferably, described venting valve, air-supply valve, material inlet valve, pan feeding valve all adopt electronic blade type gate valve.The advantage of electronic blade type gate valve is laborsaving when using and easily controls.
As preferably, described balancing gate pit is cylindrical shape, and it is highly 2m, and diameter is 2m.
The beneficial effects of the utility model are:
(1) greatly reduced the duration of runs of pan feeding pump by this product, reduce the wearing and tearing of equipment, eliminate the drawback that pan feeding pump brings directly to filter press charging, reduce accident rate; A press filtration also shortens 5min circulation timei, improves production efficiency.
(2) a non-woven filter cloth filter screen is installed between high-pressure blast main line and valve, in case valve fit badly and the blast of high-pressure blast pipeline expects pressure lower than the people of pump time, black water pollution high voltage wind main line, causes the damage of other pneumatic equipments.
(3) replace manual flanged gate valve with electrically operated valve, be conducive to sequencing in the future and automatically control, also reduce the labour intensity of workman, improve operating efficiency.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model embodiment.
Label declaration: balancing gate pit 1, air injection pipe 2, air-supply valve 3, venting valve 4, electro connecting pressure gauge 5, material inlet valve 6, pan feeding valve 7, pan feeding pump 8, filter press 9, non-woven filter cloth filter screen 10.
Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is described in further detail, the pan feeding pump 8 in the present embodiment, filter press 9, and each valve is prior art, therefore represent by means of only simple block diagram in the accompanying drawings.
Embodiment one: see Fig. 1, this product comprises balancing gate pit 1, air injection pipe 2, air-supply valve 3, venting valve 4, electro connecting pressure gauge 5, material inlet valve 6, pan feeding valve 7, pan feeding pump 8 and filter press 9, the top of balancing gate pit 1 is provided with air injection pipe 2, the rear of air injection pipe 2 is provided with air-supply valve 3, air injection pipe 2 stage casing is provided with venting valve 4, the import of air injection pipe 2 is provided with non-woven filter cloth filter screen 10, balancing gate pit 1 is provided with electro connecting pressure gauge 5, the top of side, balancing gate pit 1 is connected with pan feeding pump 8 by material inlet valve 6, and bottom is connected with filter press 9 by pan feeding valve 7.
Venting valve 4 in the present embodiment, air-supply valve 3, material inlet valve 6, pan feeding valve 7 all adopt electronic blade type gate valve.The advantage of electronic blade type gate valve is laborsaving when using and easily controls, and balancing gate pit 1 is cylindrical shape, and it is highly 2m, and diameter is 2m.
The practical operation method of the present embodiment product: shut air-supply valve 3 and venting valve 4, open pan feeding valve 7; Start pan feeding pump 8, open material inlet valve 6, black water enters balancing gate pit 1 simultaneously, certainly flows through pan feeding valve 7 and enters filter press 9; Because the incipient flow of pan feeding pump 8 is large, the coal slime water yield that balancing gate pit 1 enters is greater than the amount of outflow, just can accumulate considerable black water in balancing gate pit 1, but along with the continuous increase of pressure in balancing gate pit 1, people expects that the flow of pump also constantly reduces.When the pressure in balancing gate pit 1 reaches 0.4MPa, electro connecting pressure gauge 5 cuts off the power supply of pan feeding pump 8, close material inlet valve 6 simultaneously, then open air-supply valve 3, utilize the high-pressure blast of 0.6MPa to continue to filter press 9 charging, the black water accumulated in balancing gate pit 1 until black water completes dehydration, close air-supply valve 3 and pan feeding valve 7, slowly open venting valve 4 and discharge overbottom pressure in balancing gate pit 1, a feed cycle terminates, and then enters next circulation.
Above content described in this description is only to the explanation of the utility model structure example.The utility model person of ordinary skill in the field can make various amendment or supplements or adopt similar mode to substitute to described specific embodiment; only otherwise depart from structure of the present utility model or surmount this scope as defined in the claims, protection domain of the present utility model all should be belonged to.
