Abstract
The utility model relates to a fluid mixing device, particularly an automatic proportioning and adding device for diluting underground emulsified oil and auxiliary agents in a coal mine. A cylindrical body is arranged between a water inlet pipe and a water outlet pipe, and a left end on the body is provided with a conical gradual expansion pipe which is narrowed inwards. An annular groove is communicated between the small ends of two internal cones, and a side cylindrical hole is communicated with the radical direction of the annular groove. A cylinder-shaped shutoff valve seat whose both ends are open is arranged in the side cylindrical hole of the body, and a spiral spring and a steel ball are arranged in the valve seat. The opening of the upper end of the valve seat is communicated with a liquid adding pipe. Therefore, the utility model can automatically prepare liquid, mix evenly, and proportion accurately, and the cost is low.
Description
The utility model relates to a kind of liquid mixing equipment, refers in particular to oil emulsion and the adding mechanism for automatical proportioner that falls the auxiliary agent dilution under the coal mine.
At present, because the water under the mine is to introduce the dilution dosing that mining face under mine (general press water greater than 1.5MPa) supplies oil emulsion and depositing dust auxiliary agent from the ground trunk line, the centre must possess excessive device, supplies the dilution flow with normal pressure water; Common device has ram pump, micro-proportioning pump etc., not only cost an arm and a leg, and proportion speed degree, mixing uniformity is all undesirable.
In view of this, the purpose of this utility model provides a kind of liquid adding mechanism for automatical proportioner, can directly add quantitative oil emulsion and depositing dust auxiliary agent in press water flows automatically, and simple in structure.
The purpose of this utility model is achieved in that it is provided with the body of a cylinder between rising pipe and water inlet pipe, has the circular cone nozzle that inwardly dwindles in this body left end, has the circular cone increaser that inwardly dwindles in the left end, between the small end of two female cones, be communicated with a ring groove, and radially be communicated with a side cylindrical hole at this ring groove; The cylinder barrel shaped that is provided with a both ends open in the side cylindrical hole of the body valve seat that dams in this valve seat that dams a volute spring and steel ball are set, and this valve seat upper end open of damming is communicated with liquid adding tube.
Owing to adopt such scheme: can automatic liquid matching, mix, proportioning is also comparatively accurate, and simple in structure, cheap.
Below in conjunction with drawings and Examples the utility model is further specified.
The synoptic diagram of Fig. 1 the utility model embodiment.
Among the figure: 1. rising pipe 2. bodies 21. ring grooves 22. circular cone nozzles
Valve seat 31. volute springs 23. circular cone increaser 3. dams
32. steel ball 4. liquid adding tubes 5. spinner-type flowmeters 6. water inlet pipes
Body is a cylindrical shell.Left and right two ends have cylindrical hole, 20 °～40 ° of the circular cone nozzle 22(cone angles that left side cylindrical hole connection is inwardly dwindled, 8～20 millimeters of end diameters), 10 °～15 ° of the circular cone increaser 23(cone angles that right cylindrical hole connection is inwardly dwindled, 8～20 millimeters of end diameters); Between the small end of circular cone nozzle 22 and circular cone increaser 23, the diameter that is communicated with this ring groove of ring groove 21(is greater than two female cone end diameters), radially also be communicated with a side cylindrical hole at ring groove 21.
The valve seat 3 that dams is the both ends open cylindrical drum.The side cylindrical hole secure fit of its lower end outer rim and body 2, and volute spring 31 and steel ball 32 are set in the valve seat 3 that dams, upper port is communicated with liquid adding tube 4(upper port diameter again less than steel ball 32 diameters), these liquid adding tube 4 other ends are communicated with a spinner-type flowmeter 5, pure concentration liquid line (oil emulsion and depositing dust auxiliary agent).
Water inlet pipe 6 and rising pipe one end are communicated with the left and right cylinder nose end at body 2 respectively.
The principle of work of present embodiment:
When turning on the valve of water inlet pipe 6, press water flows in the circular cone nozzle 22 of main body 2 through the water ga(u)ge (not shown), current after circular cone nozzle 22 quickens are directly injected in the circular cone increaser 23, at this moment, ring groove 21 produces underbalance effect, under the effect of negative pressure, volute spring 31 stressed contractions, steel ball 32 leaves the upper port of the valve seat 3 that dams, so, the liquid of pure concentration is through spinner-type flowmeter 5, the valve seat 3 that dams enters ring groove 21, be inhaled into circular cone increaser 23 with water and fully mix, send in the sprinkler tip of emulsion box or coal-face (not shown).When the beginning proportioning is mixed,, adjust the flow of spinner-type flowmeter 5, to reach the proportioning of strength of fluid more accurately by observing the size of water ga(u)ge;
When closing the valve of rising pipe 1, circular cone nozzle 22 quits work, and does not also just produce underbalance effect in the ring groove 21, and volute spring 31 is pushed down the upper port that steel ball 32 seals the valve seat 3 that dams all the time, has blocked the passage of press water and pure concentration liquid.
Claims (3)
1, a kind of liquid adding mechanism for automatical proportioner, it is characterized in that: the body that between rising pipe and water inlet pipe, is provided with a cylinder, has the circular cone nozzle that inwardly dwindles in this body left end, has the circular cone increaser that inwardly dwindles in the left end, between the small end of two female cones, be communicated with a ring groove, and radially be communicated with a side cylindrical hole at this ring groove; The cylinder barrel shaped that is provided with a both ends open in the side cylindrical hole of the body valve seat that dams in this valve seat that dams a volute spring and steel ball are set, and this valve seat upper end open of damming is communicated with liquid adding tube.
