Detailed Description

In order to make the utility model realize that technical means, creation characteristics, achievement purpose and effect are clearer and easily understand, it is right to combine below the figure and the detailed implementation mode the utility model discloses do further explanation:

as shown in fig. 1 to fig. 3, the utility model provides an acid-base solution preparation device, which comprises: the device comprises a liquid preparation tank 1, an air guide pipe 2, an air valve 3 and an air pump (not shown), wherein the air guide pipe 2 is arranged in the bottom of the liquid preparation tank 1, the air guide pipe 2 is communicated with the external air pump, and the air pump is used for injecting air to liquid in the liquid preparation tank 1 through the air guide pipe 2; the air duct 2 includes: the spraying device comprises a spraying pipe 21 and a hose 22, wherein one end of the spraying pipe 21 extends out of a liquid distribution tank 1 to be detachably connected with the hose 22, an air valve 3 used for opening and closing the spraying pipe 21 is installed on the spraying pipe 21, the air valve 3 is located outside the liquid distribution tank 1, the hose 22 is used for being detachably connected with an air pump output end, the end portion, located in the liquid distribution tank 1, of the spraying pipe 21 is a spraying end, the end portion, connected with the air valve 3, of the spraying pipe 21 is an input end, and the height of the.

In order to design the nozzle 21 with a simple structure, reduce the probability of the solution entering the spraying section 213, and improve the mixing uniformity after the gas is sprayed, the nozzle 21 comprises: installation section 211, interlude 212 and blowout section 213, installation section 211 passes join in marriage fluid reservoir 1 wall, and installation section 211 one end is the input of spray tube 21, and the installation section 211 other end passes through interlude 212 and spouts section 213 intercommunication, and the tip that the interlude 212 was kept away from to blowout section 213 is the blowout end of spray tube 21. The mounting section 211 is of a straight structure so as to conveniently penetrate through the wall of the liquid distribution tank 1; the middle section 212 is of an n-shaped structure, so that the solution can enter the ejection section 213 only when flowing over the topmost part of the middle section 212, and the topmost part of the middle section 212 is far higher than the position of the installation section 211, so that the difficulty of the solution entering the installation section 211 is increased, the probability of acid or alkali entering the air pump is reduced, and the protection of the air pump is further improved; the ejection section 213 is of a horizontal and vertical structure, so that the ejected gas has certain impact force in the horizontal direction, the solution is impacted in the horizontal direction and the vertical direction, the solution is more easily mixed, the mixing effect is better, and the ejection section 213 is used for extending into the solution of the liquid preparation tank 1.

In order to realize feeding, a feed hopper 4 communicated with the interior of the liquid preparation tank 1 is arranged at the top of the liquid preparation tank 1.

In order to avoid acid or alkali corrosion to the feeder hopper 4 that the metal was made, the realization was protected feeder hopper 4, was stamped rubber hopper 5 on feeder hopper 4, and 5 top edges of rubber hopper detain feeder hopper 4 tops, blocked external impurity and got into from the clearance between rubber hopper 5 and the feeder hopper 4, and rubber hopper 5 bottom communicates to stretching into to joining in marriage the rubber tube 6 in the fluid reservoir 1, and rubber tube 6 and rubber hopper 5 all adopt elastic rubber material to make.

In order to realize the plugging of the feed hopper 4, an opening and closing mechanism 7 for opening or closing the rubber tube 6 is installed at the top of the liquid distribution tank 1, so that the rubber tube 6 is opened when needed, and the rubber tube 6 is closed when not needed.

In order to design the opening and closing mechanism 7 which is simple in structure and convenient to use, the opening and closing mechanism 7 includes: extrusion pole 71 and stopper 72, extrusion pole 71 is installed on joining in marriage fluid reservoir 1, extrusion pole 71 can join in marriage fluid reservoir 1 and feeder hopper 4 relatively and move in the horizontal direction, join in marriage fluid reservoir 1 roof and feeder hopper 4 bottom and offer the removal hole that supplies extrusion pole 71 to remove, remove downthehole wall and cave in and form slot 11, slot 11 is used for supplying stopper 72 to join in marriage fluid reservoir 1 relatively and moves in the direction parallel with extrusion pole 71, slot 11 is close to the sunken annular groove 12 that will remove the hole intercommunication that forms of the tip inner wall of rubber tube 6, annular groove 12 supplies stopper 72 to be located the rotation of extrusion pole 71 central line, extrusion pole 71 compresses tightly rubber tube 6 and makes rubber tube 6 close when stopper 72 is located annular groove 12. The design of the rubber tube 6 realizes that the opening and closing mechanism 7 can not contact with acid or alkali, avoids the damage of the opening and closing mechanism 7 caused by the contact of the acid or the alkali, and prolongs the service life of the opening and closing mechanism 7.

In order to reduce the opening and closing of the annular groove 12, the end of the socket 11 facing away from the rubber tube 6 communicates with the outside. The outer wall of the liquid preparation tank 1 blocks the limiting block 72 and keeps the state that the extrusion rod 71 is far away from the rubber tube 6.

The rubber hopper 5 and the rubber tube 6 are integrally formed at the time of manufacturing. In order to avoid the rubber tube 6 from being damaged due to excessive pressure when the extrusion rod 71 is extruded, the end part of the rubber tube 6 extruded by the extrusion rod 71 is of a hemispherical structure.

The working principle of the embodiment is as follows:

when the rubber tube 6 is opened, the extrusion rod 71 is far away from the rubber tube 6, the limiting block 72 is positioned outside the liquid distribution tank 1, the extrusion rod 71 has no extrusion effect on the rubber tube 6, and the rubber tube 6 is opened under the self elasticity.

When the rubber tube 6 needs to be closed, first, the pressing lever 71 is rotated so that the stopper 72 is aligned with the insertion groove 11; then, the pressing rod 71 is pushed toward the rubber tube 6, the stopper 72 is inserted into the insertion groove 11, the pressing rod 71 is moved, and finally the pressing rod 71 collapses the rubber tube 6, the rubber tube 6 is closed, and the stopper 72 is aligned with the annular groove 12 formed on the inner wall of the insertion groove 11, so that the state is maintained; finally, the extrusion rod 71 is rotated, so that the limit block 72 is screwed into the annular groove 12, the inner wall of the annular groove 12 blocks the extrusion rod 71 from being far away from the rubber tube 6 through the limit block 72, and the friction force between the inner wall of the annular groove 12 and the limit block 72 limits the random rotation of the extrusion rod 71, so that the state that the extrusion rod 71 is tightly pressed and closed on the rubber tube 6 is maintained.

Finally, although the present invention has been described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that the present invention can be modified or replaced by other means without departing from the spirit and scope of the present invention, which should be construed as limited only by the appended claims.
