Description

Technical Field

[0001] The utility model relates to the technical field of water reducing agent processing, in particular to a dripping liquid adding device for concrete water reducing agent. Background Art

[0002] In the existing chemical product preparation process, such as the polycarboxylate water-reducing agent preparation process, it is necessary to drop the liquid reaction reagent during stirring.

[0003] For example, a Chinese patent with publication number CN213286471U discloses a device for adding droplets of a concrete water reducing agent, including a box, a stirring shaft is vertically arranged at the center of the box, the stirring shaft is a hollow structure with an opening at the top, the top of the stirring shaft extends out of the box, an adding bottle is fixedly arranged at the center of the top of the box through a mounting frame, the bottom center of the adding bottle is connected to the top of the stirring shaft through a vertically arranged feeding pipe, and the right side of the box is sequentially arranged with a first reagent bottle, a second reagent bottle and a third reagent bottle from left to right. The utility model arranges an adding bottle at the top of the box, the stirring shaft and the stirring rod are both hollow structures, the adding bottle is connected to the stirring shaft and the stirring rod, the bottom of the stirring rod is evenly provided with through holes, the adding bottle is connected to the first reagent bottle, the second reagent bottle and the third reagent bottle through a feeding bottle, and the dropping liquid is evenly added to avoid the accumulation of the dropping liquid in one place, thereby reducing the stirring efficiency of the water reducing agent.

[0004] This patent adds the dropping liquid evenly through a hollow stirring shaft to prevent the dropping liquid from piling up. However, this patent cannot adjust the distribution range of the dropping liquid. When the height of the water reducer does not match the dropping range, for example, when the height of the water reducer is higher than the dropping range, there is no dropping liquid distributed in the upper half of the water reducer; when the height of the water reducer is lower than the dropping range, part of the dropping liquid accumulates on the top surface of the water reducer, resulting in the inability to fully mix the dropping liquid and the water reducer, thereby reducing the efficiency of uniformly stirring the water reducer. Utility Model Content

[0005] In view of the shortcomings of the prior art, the purpose of the utility model is to provide a dripping liquid adding device for concrete water reducing agent, which has the effect of improving the mixing efficiency of the water reducing agent.

[0006] The above technical objectives of the utility model are achieved through the following technical solutions:

[0007] A dripping liquid adding device for a concrete water reducing agent comprises a shell, two support plates are fixedly connected to the bottom of the shell, a screw is vertically rotatably connected inside the shell, a moving shell is threadedly connected to the outer circumference of the screw, a plurality of guide pipes are fixedly connected to the outer circumference of the moving shell, the guide pipes are communicated with the moving shell, and the outer walls of the guide pipes are hollowed out, a water pump is fixedly connected to one side of the shell, an output end of the water pump is communicated with the moving shell through a hose, and a driving part is arranged below the shell.

[0008] Through the above technical scheme, through the cooperation of the support plate, the guide pipe, the water pump and the driving part, the distribution range of the dripping liquid can be adjusted to match the height of the water reducer, so that the dripping liquid and the water reducer are more uniform from the beginning, thereby improving the efficiency of uniform stirring of the water reducer.

[0009] In a preferred example, the utility model can be further configured as follows: the driving part includes a motor fixedly connected to one side of one of the support plates, the output end of the motor is transmission-connected with an incomplete gear, a driving rod and a lead screw are rotatably connected between the two support plates, one side of one of the support plates is fixedly connected with a transmission, the driving rod and the lead screw are both transmission-connected with the transmission, a screw plate is threadedly connected to the outer circumference of the lead screw, the driving rod moves through the screw plate, a driven gear is fixedly sleeved on the outer circumference of the driving rod, the driven gear is intermittently meshed with the incomplete gear, a fixing ring is fixedly connected to one side of the support plate, the driving rod is partially located in the fixing ring, and a clockwork spring is provided between the inner circumference of the fixing ring and the driving rod, and a linkage part is provided between the screw plate and the screw.

[0010] Through the above technical solution, by cooperating with the motor, the lead screw, the transmission, the screw plate and the linkage part, the transmission can be adjusted to change the number of positive and reverse turns of the lead screw, thereby adjusting the movement distance of the screw plate, and then changing the movement range of the moving shell to make it compatible with the height of the water reducer.

[0011] In a preferred example, the utility model can be further configured as follows: the linkage part includes a spur rack fixedly connected to one side of the screw plate, a guide rod is fixedly connected to one side of the support plate, the guide rod is partially slidably inserted into the spur rack, and a linkage gear is fixedly sleeved on the outer peripheral surface of the screw, and the gear is meshed with the spur rack.

[0012] Through the above technical solution, through the cooperation of the spur rack, the linkage gear and the guide rod, when the screw plate moves, the spur rack drives the screw rod to rotate, thereby driving the moving shell to move vertically.

[0013] In a preferred example, the utility model can be further configured as follows: a rotating disk is rotatably sleeved on the upper half of the outer circumference of the screw rod, a plurality of vertical rods are fixedly connected to the bottom of the rotating disk, the bottom ends of the vertical rods are fixedly connected to the inner bottom wall of the shell, and the vertical rods slide through the moving shell.

[0014] Through the above technical solution, through the cooperation between the rotating disk and the vertical rod, when the screw rod rotates, the moving shell can only move vertically but will not rotate.
