Description

Technical Field

[0001] The utility model is applicable to the technical field of desulfurized limestone powder production, and particularly relates to a raw material proportioning device for desulfurized limestone powder production. Background Art

[0002] At present, limestone powder is the form of limestone after grinding. Limestone is also called calcium carbonate. Calcium carbonate is a common compound on the earth and can be found in rocks. It is also the main component of shells and snail shells. It exists in nature in the form of two minerals, calcite and aragonite. When producing it, it is necessary to use a variety of powdered raw materials to pour them simultaneously, and then use the corresponding mixing mechanism to mix and proportion the multiple raw materials.

[0003] However, when the proportioning and mixing mechanism used nowadays stirs and mixes multiple powdered raw materials, the multiple powdered raw materials are poured into the mixing tank simultaneously and then stirred by the corresponding stirring mechanism, so that the multiple raw materials are fully mixed to achieve the proportioning treatment of limestone powder. When the multiple powdered raw materials are stirred and mixed, a large amount of powdered raw materials will be brought into the mixing tank as the stirring frame rotates and cannot participate in the proportioning and mixing treatment of the raw materials, thereby affecting the proportioning quality of the multiple raw materials, and causing the floating powder to be unable to be quickly discharged, affecting the output of limestone powder. Therefore, we propose a raw material proportioning device for the production of desulfurized limestone powder. Utility Model Content

[0004] The main purpose of the utility model is to provide a raw material proportioning device for producing desulfurized limestone powder, which can effectively solve the problems in the background technology.

[0005] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0006] A raw material proportioning device for producing desulfurized limestone powder, comprising a mixing tank, a material storage frame is fixedly installed at the middle end of the inner side of the mixing tank, a fixing frame is fixedly installed at the inner bottom of the material storage frame, and rotating baffles are hinged at both ends of the inner bottom of the fixing frame through a rotating shaft;

[0007] A shielding cover is slidably installed on the top of the inner side of the mixing tank, and hollow frames are fixedly installed on the surfaces of both ends of the inner top of the mixing tank. A bidirectional screw is rotatably installed on the middle end of the inner side of each hollow frame through a bearing, and a transmission sleeve is movably sleeved on the outer side of each bidirectional screw. A connecting frame is fixedly installed on the outer bottom of each transmission sleeve and the top surface of the shielding cover, and a push rod is hinged between the outer sides of each two groups of the connecting frames through a rotating shaft, and the push rod is located below the outer side of the hollow frame;

[0008] A servo motor is fixedly installed on the outer surface of each hollow frame, and the side of the servo motor transmission shaft is fixedly connected to the outer top surface of the bidirectional screw rod through a coupling. A limiting groove is opened at the middle end of the bottom of each hollow frame, and the connecting frame is slidably installed inside the limiting groove. Guide rods are fixedly installed on the outer surface of the shielding cover plate, and the number of guide rods is four groups. Sliding grooves are opened inside the mixing tank and the storage frame, and the guide rods are slidably inserted into the sliding grooves.

[0009] By adopting the above technical scheme, through the rotational transmission action of the bidirectional screw on the transmission sleeve and the transmission conversion action of the push rod, a vertical driving force can be provided to the shielding cover plate, so that the shielding cover plate can be moved to the inside of the storage frame, and the top of the storage frame can be shielded and protected to prevent the stirring plate from rotating and causing the raw materials to float and move arbitrarily, thereby avoiding the inability to fully mix and proportion multiple raw materials and improving the stirring and proportioning quality of the limestone powder.

[0010] As an optional solution to the technical solution of the present application, a mounting plate is fixedly installed on the inner middle surface of the material storage frame, a rotating motor is fixedly installed on the top middle surface of the mounting plate, a transmission frame is fixedly installed on the bottom surface of the rotating motor drive shaft through a coupling, and the number of transmission frames is several groups, and a stirring plate is fixedly installed on the bottom surface of the transmission frame.

[0011] By adopting the above technical solution, the power required for the rotation of the stirring plate is provided by the driving action of the rotating motor, thereby ensuring that the raw materials stacked inside the storage frame are mixed and proportioned.

[0012] As an optional solution of the technical solution of the present application, a mounting groove is opened at the middle end of the shielding cover plate, and the mounting groove and the rotating motor are in the same vertical position.

[0013] By adopting the above technical solution, by providing a mounting groove in the middle of the shielding cover, it is ensured that when the shielding cover moves vertically, the rotating motor can be inserted into the mounting groove, thereby preventing it from causing vertical movement of the shielding cover.

[0014] As an optional scheme of the technical solution of the present application, both ends of the outer side of the mixing tank are obliquely fixedly connected with a feed pipe, and both end surfaces of the inner bottom of the mixing tank are fixedly installed with guide plates, and a discharge trough is opened at the middle end of the bottom of the mixing tank. Both end surfaces of the inner bottom of each mixing tank are slidably hinged with an electric push rod through a rotating shaft, and the top of the electric push rod transmission shaft is hinged to the bottom surface of the rotating baffle through the rotating shaft.

[0015] By adopting the above technical solution, the power required for rotating and opening the rotating baffle is achieved through the driving action of the electric push rod.

[0016] Compared with the prior art, the utility model has the following beneficial effects:

[0017] 1. The technical solution of the present application is a raw material proportioning device for the production of desulfurized limestone powder. By sleeve-connecting a transmission sleeve on both sides of a bidirectional screw rod and combining the rotational transmission action of the bidirectional screw rod on the transmission sleeve, when the bidirectional screw rod rotates, the two sets of transmission sleeves can synchronously move horizontally in opposite directions or relative to each other inside a hollow frame. Subsequently, combined with the transmission conversion action of a push rod, the horizontal movement force of the transmission sleeve can be converted into a vertical driving force for a shielding cover plate, so that the shielding cover plate can be moved into the storage frame, and the top of the storage frame can be shielded and protected to prevent the stirring plate from rotating and driving the raw materials to float and move arbitrarily, thereby preventing multiple raw materials from being unable to be fully mixed and proportioned, and improving the stirring and proportioning quality of the limestone powder.

[0018] 2. The technical solution of the present application is a raw material proportioning device for the production of desulfurized limestone powder. By arranging two groups of rotating baffles inside the storage frame and an electric push rod at the bottom of the rotating baffle, the corresponding downward pulling force can be provided to the rotating baffle under the driving action of the electric push rod, so that the rotating baffles can be synchronously rotated and opened inside the storage frame to facilitate the dumping of the mixed and proportioned raw materials, thereby improving the material discharge efficiency and further improving the proportioning and mixing efficiency of the limestone powder.
