Description

Technical Field

[0001] The utility model belongs to the technical field of ceramics, and particularly relates to a gravity-free mixing device for stone materials with automatic batching. Background Art

[0002] The gravity-free mixer makes full use of the principle of convective mixing, that is, it uses the upward throwing movement of materials in the mixer to form a flowing layer, generating instantaneous weightlessness to achieve the best mixing effect state. It is widely used in the drying and mixing of powders such as dry mortar, chemicals, pesticides, detergents, pigments, food, monosodium glutamate, milk powder, salt, feed, chemicals, ceramics, plastics, and rubber additives.

[0003] In order to reduce the labor intensity of workers, some gravity-free mixers are equipped with screw conveyors to convey materials. People only need to pour the materials into the feed hopper on the screw conveyor. However, for the mixing of multiple materials, it is necessary to follow a certain ratio. Workers need to weigh the materials before putting them into the feed hopper, which is time-consuming and has low efficiency.

[0004] Therefore, we have proposed a gravity-free mixing device for stone materials with automatic batching. Content of the Utility Model

[0005] The purpose of the utility model is to solve the disadvantages in the prior art that for the mixing of multiple materials, it is necessary to follow a certain ratio, and workers need to weigh the materials before putting them into the feed hopper, which is time-consuming and has low efficiency, and to propose a gravity-free mixing device for stone materials with automatic batching.

[0006] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0007] A gravity-free mixing device for stone materials with automatic batching, comprising:

[0008] The gravity-free mixer main body, one side of the gravity-free mixer main body is provided with a feeding port, one side of the feeding port is hinged with a hatch, one side of the gravity-free mixer main body is equipped with a screw conveyor, the outer wall of the screw conveyor is fixedly provided with a feed hopper, and a connecting pipe is fixedly connected between the screw conveyor and the gravity-free mixer main body;

[0009] It further includes a bracket, the bracket is installed on one side of the screw conveyor, the surface of the bracket is fixedly provided with a plurality of weighing devices, the surface of each weighing device is equipped with a storage bucket, the outer wall of the storage bucket is fixedly connected with a feeding pipe, an electromagnetic valve is arranged on the outer wall of the feeding pipe, a control box and a guiding box are respectively fixedly provided on both sides of the bracket, the feeding pipe is fixedly connected with the guiding box, and the bottom end of the guiding box is located inside the feed hopper;

[0010] An anti-blocking mechanism, the anti-blocking mechanism is arranged on one side of the feeding pipe and is used to dredge the materials in the feeding pipe.

[0011] In a possible design, the anti-blocking mechanism includes a rack and a rotating rod. The rack is fixedly arranged on the surface of the bracket, the rotating rod rotates through the outer wall of the feeding pipe, gears and paddles are respectively fixedly arranged at both ends of the rotating rod, the gear meshes with the rack, and the paddle is located inside the feeding pipe.

[0012] In a possible design, a sliding plate is fixedly arranged at the bottom of the storage barrel, a bottom plate is fixedly arranged on the surface of the weighing device, a plurality of springs are fixedly arranged between the sliding plate and the bottom plate, and two guide rails are fixedly arranged on the surface of the bracket. The sliding plate is slidably connected with the guide rails.

[0013] In a possible design, a plurality of spherical grooves are formed in the outer walls on both sides of the sliding plate, and balls are arranged in the plurality of spherical grooves.

[0014] In a possible design, a sealing ring is fixedly arranged on the outer wall of the bottom end of the material guiding box, and the sealing ring is in contact with the inner wall of the feeding hopper.

[0015] In a possible design, a top cover is hinged to the top end of the storage barrel.

[0016] In this application, during use, the control box is used to set the material ratios of various materials, and then the start key is pressed. The control box opens the solenoid valve according to the settings. The materials pass through the feeding pipe and the feeding hopper from the storage barrel, and enter the connecting pipe under the transportation of the screw conveyor, and finally are transported into the main body of the gravity mixer. The weighing device weighs the weight of the storage barrel in real time. When the weight decreases to the set value, the solenoid valve is automatically closed. At the same time, due to the continuous transportation of the materials, the weight of the storage barrel decreases, the spring pushes the storage barrel to rise, the storage barrel drives the feeding pipe to rise, the feeding pipe drives the rotating rod to rise, the gear rotates under the action of the rack, and then drives the paddle to rotate. The paddle dredges the materials to prevent the materials from blocking in the feeding pipe. When all the materials are transported, the main body of the gravity mixer is started to mix the materials.

[0017] Beneficial effects:

[0018] In the present utility model, for the automatic batching stone gravity mixing device, through the setting of multiple structures such as the weighing device, the control box and the storage barrel, the material ratio and feeding can be automatically completed, saving the time of the staff and improving the processing efficiency;

[0019] In the present utility model, for the automatic batching stone gravity mixing device, through the setting of multiple structures such as the gear, the rack and the paddle, the materials in the feeding pipe can be dredged to avoid the situation of pipeline blockage and ensure the stable transportation of the materials;

[0020] In the utility model, the material proportioning and feeding can be completed automatically, which saves the time of the staff and improves the processing efficiency. The material in the feeding pipe can also be guided to avoid the blockage of the pipeline and ensure the stable transportation of the material. BRIEF DESCRIPTION OF THE DRAWINGS
