Technical Field

[0001] The utility model relates to the technical field of concrete admixtures, and particularly to a proportioning device for premixing mortar admixtures. Background Art

[0002] The proportioning device for premixing mortar admixtures is a device specifically used in building construction sites or precast concrete factories, which enables the proportional feeding and mixing of mortar and admixtures, avoiding errors in manual addition and mixing. Among them, the proportioning device for premixing mortar admixtures is applicable to various types of mortar admixtures, such as water reducers, early strength agents, and waterproof agents, meeting different construction requirements and improving construction effects, and having significant advantages in large-scale construction projects.

[0003] However, most of the existing proportioning devices for premixing mortar admixtures are of single storage hopper structure, and it is difficult to accommodate various types of admixtures inside. When multiple types of admixtures need to be put in, it is necessary to wait for the storage hopper to finish discharging before putting in other types of admixtures. In addition, the existing mortar admixture batching devices have high manufacturing costs and complex mechanical structures. Solenoid valves need to be installed on the pipelines for multi-discharge batching to control the discharge switches, thus increasing the production and maintenance costs.

DETAILED DESCRIPTION

[0018] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0019] Please refer to Figure 1 , an embodiment of the present invention provides a proportioning device for premixing mortar admixtures, including: a mixing tank 1, a box body 8, and a batching barrel 9.

[0020] Among them, as Figures 1-3 shown, the box body 8 is embedded at the top of the mixing tank 1. The bottom of the box body 8 is provided with through holes. The top of the box body 8 is communicated with a batching pipe 3. The batching barrel 9 is rotatably installed inside the box body 8 through bearings. Three partition plates 19 are symmetrically installed on the inner wall of the batching barrel 9. Three connecting pipes 15 are symmetrically communicated with the bottom of the batching barrel 9. A second motor 11 is installed on the outer wall of the box body 8. A gear ring 10 is fixedly connected to the outer wall of the batching barrel 9. A gear 12 is fixedly connected to the rotating shaft of the second motor 11. The gear 12 meshes with the gear ring 10.

[0021] During use, the admixtures are added into the batching barrel 9 inside the box body 8 through the batching pipe 3. Three batching grooves are separated by the three partition plates 19 inside the batching barrel 9. The second motor 11 is driven to rotate the gear 12 to mesh with the gear ring 10, thereby driving the batching barrel 9 to rotate, so that the three types of admixtures can be sequentially added into the three separated batching grooves when being put in, in cooperation with the rotation of the batching barrel 9.

[0022] Furthermore, a first motor 2 is installed on the top of the mixing tank 1. The rotating shaft of the first motor 2 penetrates through the mixing tank 1 and is fixedly connected with a stirring blade 4. The first motor 2 can drive the stirring blade 4 to rotate inside the mixing tank 1 to stir and mix the mortar and the admixtures.

[0023] In this embodiment, as Figures 1-4 shown, an annular plate 13 is fixedly connected to the inner wall of the top of the mixing tank 1. An electromagnet 16 is installed on the inner wall of the annular plate 13. A pipe joint 14 is installed at the bottom end of the connecting pipe 15. A magnetic ball 17 is provided on the inner wall of the pipe joint 14. The cross-section of the pipe joint 14 is conical.

[0024] During use, the tops of the three connecting pipes 15 at the bottom of the batching barrel 9 are respectively communicated with three batching tanks, and pipe connectors 14 with magnetic balls 17 are respectively installed at their bottoms. The magnetic balls 17 in the pipe connectors 14 move upward a certain distance under the influence of magnetic force when passing through the electromagnet 16 in the activated state, opening the bottom opening of the pipe connector 14 to realize the discharge of the admixture in the batching tank. When the electromagnet 16 is closed, the magnetic balls 17 descend along the conical surface of the pipe connector 14 under the influence of gravity and gradually block the opening.

[0025] Further, referring to Figure 2 and Figure 4 , a limiting plate 18 is fixedly connected to the inner wall of the top of the mixing tank 1. The limiting plate 18 is located inside the annular plate 13, and the limiting plate 18 is arc-shaped. The limiting plate 18 can guide the pipe connector 14 to pass through and approach the electromagnet 16.

[0026] Specifically, a feed pipe 5 is communicated with the top of the mixing tank 1, and a discharge pipe 6 is communicated with the bottom of the mixing tank 1. Mortar can be input through the feed pipe 5 and discharged outward through the discharge pipe 6 after stirring and mixing. A tank support 7 is installed at the bottom of the mixing tank 1, and the tank support 7 can place the mixing tank 1 vertically.

[0027] Summarize and sort out the working steps of this solution according to the above technical solution: When the present utility model is in use, the admixture is added into the batching barrel 9 in the box body 8 through the batching pipe 3. The batching barrel 9 is divided into three batching tanks by three partition plates 19. The gear 12 is driven to rotate by the second motor 11 and meshes with the gear ring 10, thereby driving the batching barrel 9 to rotate, enabling the three types of admixtures to be sequentially added into the separated three batching tanks when being put in, which is convenient for the operator to put in according to different types of admixtures.

[0028] The tops of the three connecting pipes 15 at the bottom of the batching barrel 9 are respectively communicated with three batching tanks, and pipe connectors 14 with magnetic balls 17 are respectively installed at their bottoms. The magnetic balls 17 in the pipe connectors 14 move upward a certain distance under the influence of magnetic force when passing through the electromagnet 16 in the activated state, opening the bottom opening of the pipe connector 14 to realize the discharge of the admixture in the batching tank. Magnetic control of the discharge can be completed without installing solenoid valves on each connecting pipe 15, and the discharge control accuracy is relatively high and the cost is low.

[0029] Parts not involved in the present utility model are the same as or can be implemented by using the prior art. Although the embodiments of the present utility model have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present utility model. The scope of the present utility model is defined by the appended claims and their equivalents.
