Description

Technical Field

[0001] The utility model relates to the technical field of polymer mortar production, in particular to a device for accurately conveying polymer mortar additives. Background Art

[0002] Polymer mortar is made by mixing cement, aggregate and organic polymers that can be dispersed in water.

When in use, the material is put into the shell, and under the action of the guide ring, all the material flows into the top of the filter screen, and after being filtered by the filter screen, the material enters the lower end of the shell. The large particles in the material can be filtered out through the filter screen to avoid blocking the outlet at the lower end of the shell, thereby improving the feeding effect. When the feeding speed needs to be adjusted, the threaded shaft is rotated, and the threaded shaft drives the baffle to move, so that the position of the baffle can be adjusted, thereby changing the opening and closing size of the outlet below the shell to adjust the feeding speed and improve the use effect.

[0004] In the above utility model, the threaded shaft is rotated, and the threaded shaft drives the baffle to move, so that the polymer mortar raw material can enter the interior of the mixer through the outlet below the shell. The introduction amount of the polymer mortar raw material needs to be controlled by the operator based on experience, and precise control cannot be achieved, which reduces the practicality of the use of this utility model.

[0005] Currently, no effective solution has been proposed for the problems in the related technologies. Utility Model Content

[0016] (III) Beneficial effects

[0017] Compared with the prior art, the utility model provides a device for accurately conveying the amount of polymer mortar additives, which has the following beneficial effects:

[0018] (1) The utility model adopts a connecting orifice plate and a mounting orifice plate. Before actually using the polymer mortar additive dosage precision delivery device, the operator first installs the mounting orifice plate with the mixer, and then fixes the connecting flange with the feed end of the mixer. After that, the polymer mortar raw materials are inserted into the interior of the covering cover through two sets of feed ports. The polymer mortar raw materials will fall on the upper part of the filter mesh orifice plate. As the polymer mortar raw materials are added, when the added amount reaches the preset value of the weight sensor, the weight sensor will send a signal to the controller, and the controller will open and close the electric gate valve and operate the drive motor at the same time. The output end of the drive motor will drive the fixed orifice plate and the auger to rotate through the mounting shaft. Since the gap lengths between the first metal protrusion and the second metal protrusion and the mounting shaft are the same, the first metal protrusion will intermittently hit the mounting shaft. When the first metal protrusion hits the second metal protrusion, the force on the moving orifice plate will drive the filter orifice plate to move up. When the filter orifice plate moves to the highest point, it will move downward due to gravity, waiting for the first metal protrusion to hit the second metal protrusion again. The two sets of vertical rods ensure the stability of the up and down movement of the filter orifice plate. The up and down moving filter orifice plate will screen the polymer mortar raw materials. Qualified polymer mortar raw materials will pass through the filter orifice plate, and then pass through the guide hopper, electric plug valve, telescopic hose and connecting flange in turn, and finally qualified polymer mortar raw materials will enter the interior of the mixer. The rotating auger can prevent the guide hopper from being blocked. Through the set connecting orifice plate and mounting orifice plate, the amount of polymer mortar raw materials introduced into the mixer can be accurately controlled, thereby improving the practicality of the device for accurately delivering the amount of polymer mortar additives.

[0019] (2) The utility model adopts a covering cover. According to the above operation, the polymer mortar raw materials are inserted into the interior of the covering cover through two groups of feed ports. The polymer mortar raw materials include cement, aggregate and organic polymers that can be dispersed in water. The polymer mortar raw materials are usually packaged and used in packaging bags. The packaging bags are inserted into the interior of the covering cover through two groups of feed ports. The packaging bags will gather on multiple groups of support rods. When the added amount reaches the preset value of the weight sensor, the weight sensor will send a signal to the controller, and the controller will open and close the electric gate valve and operate the drive motor at the same time. The output end of the drive motor will be installed The mounting shaft drives the fixed orifice plate and the auger to rotate. The mounting shaft drives multiple sets of cutting knives to rotate through multiple sets of sleeve rings. The rotating cutting knives will break the packaging bags, and the polymer mortar raw materials will eventually fall on the upper part of the filter mesh orifice plate. When the polymer mortar raw materials are added, two sets of sealing covers and two sets of sealing plugs are pulled out, and the packaging bag fragments and unqualified polymer mortar raw materials inside the feed barrel and the covering cover can be taken out. Through the set covering cover, the polymer mortar raw materials can be directly added and used without the need for operators to unpack the packaging bags, which brings convenience to the addition of polymer mortar raw materials in the polymer mortar additive and precise conveying device.

[0036] Working principle:

[0037] Before actually using the polymer mortar additive dosage precision delivery device, the operator first installs the mounting orifice plate 10 with the mixer, and then fixes the connecting flange 14 with the feed end of the mixer, and then inserts the polymer mortar raw material into the interior of the covering cover 5 through the two sets of feed ports 23. The polymer mortar raw material will fall on the upper part of the filter mesh orifice plate 18. As the polymer mortar raw material is added, when the added amount reaches the preset value of the weight sensor 11, the weight sensor 11 will send a signal to the controller, and the controller will open and close the electric gate valve 3 and start the drive motor 6 at the same time.

The two sets of vertical rods 27 ensure the stability of the filter orifice plate 18 moving up and down. The filter orifice plate 18 moving up and down will screen the polymer mortar raw materials. Qualified polymer mortar raw materials will pass through the filter orifice plate 18, and then pass through the guide hopper 2, the electric plug valve 3, the telescopic hose 13 and the connecting flange 14 in turn. Finally, the qualified polymer mortar raw materials will enter the interior of the mixer. The rotating auger 4 can prevent the guide hopper 2 from being blocked, and the By setting the connecting hole plate 9 and the mounting hole plate 10, the introduction amount of the polymer mortar raw material into the mixer can be accurately controlled, thereby improving the practicality of the device for accurately conveying the amount of polymer mortar additives.

The polymer mortar raw materials include cement, aggregate and organic polymers that can be dispersed in water. Packaging bags are mostly used to complete the packaging and use of the polymer mortar raw materials.
