Description

Technical Field

[0001] The utility model belongs to the technical field of cement raw material lifting and mixing devices, and particularly relates to an auxiliary device for mixing cement raw materials. Background Technique

[0002] At present, in the process of cement production, various raw materials need to be mixed to produce various qualified cements. Most of these cement raw materials are in powder form, and the materials to be added are also added in powder form. However, in some process treatments, some materials have lumps, so they need to be filtered before further treatment. In the process of treating some cement materials, due to the relatively high equipment, on-site workers often use shovels to gradually feed the cement raw materials into the equipment, which is inefficient and burdensome for workers.

[0003] Chinese Patent with the authorization announcement number CN204505543U discloses an auxiliary device for lifting and mixing cement raw materials, including a feeding chamber. The right side of the feeding chamber is connected to a lifting chamber. An upper motor is arranged in the upper part of the lifting chamber. The lower part of the upper motor is connected to a motor shaft, and a spiral blade is arranged on the side of the motor shaft; the upper right part of the lifting chamber is connected to a discharge pipe, the right side of the discharge pipe is connected to a stirring chamber, a filter plate is arranged in the upper part of the stirring chamber, a feeding chamber is arranged above the filter plate, a baffle is arranged in the lower part of the stirring chamber, a discharge chamber is arranged below the baffle, and a blanking pipe is arranged below the discharge chamber; the left side of the discharge chamber is connected to a support plate, the left side of the support plate is connected to the right side of the lifting chamber, and a left support column is connected to the lower part of the support plate. The right side of the discharge chamber is connected to a right support column. This utility model device can effectively lift the cement raw materials, improve the feeding efficiency, replace manual labor, reduce the burden on workers, and facilitate mixing treatment after lifting, and facilitate adding other filtered auxiliary materials after lifting, improving the mixing effect of cement raw materials and facilitating use according to needs.

[0004] However, the above patent has the following disadvantages:

[0005] During the process of lifting cement by the above patent, if there is less cement powder in the feeding chamber, it is difficult for the spiral blade to convey the remaining less cement powder to the stirring chamber, resulting in waste of cement. And in real scenarios, cement powder raw materials are usually packed in woven bags and stacked in the construction site warehouse. Then, the cement powder is prone to caking due to problems such as rain or humidity in the warehouse. Part of the wet cement is easily adhered to the spiral blade and difficult to remove, further causing waste of cement raw materials. Content of the Utility Model

[0006] In order to overcome the deficiencies of the prior art, the technical problem to be solved by the present utility model is to facilitate the feeding work of workers and reduce the labor burden of workers by arranging the material box at a lower position, and to continuously lift the cement powder in the material box and feed it into the mixing drum for mixing by the rotation of the screw. When there is less cement remaining in the material box, the device is rotated as a whole by the hydraulic cylinder, so that the feeding pipe changes from a downward inclination to an upward inclination state, and the remaining cement can also enter the mixing drum for mixing by gravity, thereby reducing waste. And because the inclination direction of the screw changes, the cement adhering to the spiral surface on one side of the screw will also fall off under the action of gravity, further reducing waste.

[0007] In order to achieve the above object, the present utility model provides the following technical solution: An auxiliary device for mixing cement raw materials, including a bottom plate, two brackets are fixedly connected to the bottom plate, two symmetrically arranged mixing drums are rotatably connected between the two brackets, the two mixing drums are combined into a complete cylinder body, one end of the mixing drum is communicated with a feeding pipe, the end of the feeding pipe extending out of the mixing drum is fixedly connected with a material box, a screw is rotatably connected in the feeding pipe, and one end of the screw away from the material box is fixedly connected with a stirrer.

[0008] By arranging the material box at a lower position and continuously lifting the cement powder in the material box and feeding it into the mixing drum for mixing by the rotation of the screw, it is convenient for workers to carry out the feeding work and reduces the labor burden of workers.

[0009] The mixing drum is conical, a discharge port is arranged at the bottom between the two mixing drums, and a sealing plug is arranged in the discharge port.

[0010] When the two conical mixing drums discharge materials, it is beneficial for the materials to gather at the discharge port, thus facilitating the discharge of materials.

[0011] A plurality of spiral stirring rods are uniformly distributed in the circumferential direction on the stirrer, and the spiral directions of the stirring rods at both ends of the stirrer are opposite.

[0012] The stirrer is used to stir the materials, and when discharging materials, the rotation of the stirrer with opposite spiral directions at both ends has an aggregating effect on the materials, further facilitating the discharge of materials.

[0013] A second hinge is fixedly connected to the bottom plate, a first hinge is fixedly connected to the outer wall of the feeding pipe, the movable end of the second hinge is fixedly connected with a hydraulic cylinder, and the extending end of the hydraulic cylinder is fixedly connected with the movable end of the first hinge.

[0014] When there is less cement remaining in the material box, the device is rotated as a whole by the hydraulic cylinder, so that the feeding pipe changes from a downward inclination to an upward inclination state, and the remaining cement can also enter the mixing drum for mixing by gravity, thereby reducing waste.

[0015] On one side of the end of the mixing drum away from the material box, a motor base is fixedly connected. A motor is fixedly connected to the motor base. The power output end of the motor passes through the motor base and is drivingly connected to a driving wheel. One end of the screw rod away from the material box passes through the mixing drum and is rotatably connected to the mixing drum. One end of the screw rod passing through the mixing drum is fixedly connected to a driven wheel. A transmission belt is drivingly connected between the driven wheel and the driving wheel.

[0016] In summary, compared with the prior art, the beneficial effects of the present utility model are as follows:

[0017] (1) By arranging the material box at a lower position and using the rotation of the screw rod to continuously lift the cement powder in the material box and enter the mixing drum for mixing, it is convenient for workers to carry out the feeding work and reduces the labor burden of the workers.

[0018] (2) When there is less cement remaining in the material box, the device as a whole is rotated by the hydraulic cylinder, so that the feeding pipe changes from a downward inclination to an upward inclination state, and the remaining cement can also enter the mixing drum for mixing by using gravity, thereby reducing waste.

[0024] In order to enable those skilled in the art to better understand the solution of the present utility model, the technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model.

[0025] Refer to Figures 1-5 , an auxiliary device for mixing cement raw materials, including a bottom plate 10. Two brackets 41 are fixedly connected to the bottom plate 10. Two symmetrically arranged mixing drums 40 are rotatably connected between the two brackets 41. The two mixing drums 40 form a complete cylinder. One end of the mixing drum 40 is communicated with a feeding pipe 14. One end of the feeding pipe 14 extending out of the mixing drum 40 is fixedly connected to a material box 15. A screw rod 16 is rotatably connected in the feeding pipe 14. One end of the screw rod 16 away from the material box 15 is fixedly connected to a stirrer 47.

[0026] Reference Figures 1-3 , the mixing drum 40 is conical, a discharge port 42 is provided at the bottom between the two mixing drums 40, and a sealing plug 43 is provided in the discharge port 42.

[0027] When the two conical mixing drums 40 discharge materials, it is beneficial for the materials to gather at the discharge port 42, thus facilitating the discharge of materials.

[0028] A plurality of spiral stirring rods are uniformly distributed on the stirrer 47 in the circumferential direction, and the spiral directions of the stirring rods at both ends of the stirrer 47 are opposite.

[0029] The stirrer 47 is used to stir the materials. When discharging materials, the rotation of the stirrer 47 with opposite spiral directions at both ends plays an aggregating effect on the materials, further facilitating the discharge of materials.

[0030] Reference Figure 3 , a second hinge 46 is fixedly connected to the bottom plate 10, a first hinge 45 is fixedly connected to the outer wall of the feed pipe 14, the movable end of the second hinge 46 is fixedly connected to a hydraulic cylinder 44, and the extending end of the hydraulic cylinder 44 is fixedly connected to the movable end of the first hinge 45.

[0031] When there is less cement remaining in the material box 15, the whole device is rotated through the hydraulic cylinder 44, so that the feed pipe 14 changes from a downward inclination state to an upward inclination state, and the remaining cement can also enter the mixing drum 40 for mixing by using gravity, thereby reducing waste.

[0032] Reference Figures 1-3 , a motor base 20 is fixedly connected to one side of the end of the mixing drum 40 far away from the material box 15, a motor 19 is fixedly connected to the motor base 20, the power output end of the motor 19 passes through the motor base 20 and is drivingly connected to a driving wheel 23, one end of the screw rod 16 far away from the material box 15 passes through the mixing drum 40 and is rotatably connected to the mixing drum 40, a driven wheel 22 is fixedly connected to the end of the screw rod 16 passing through the mixing drum 40, and a transmission belt 21 is drivingly connected between the driven wheel 22 and the driving wheel 23.

[0033] In this embodiment, initially, the patent is connected to the power supply and the control system, and the hydraulic cylinder 44 remains in a contracted state. Then, the feed pipe 14 and the screw rod 16 are in a downward inclined state, the material box 15 is located at a low position, and the sealing plug 43 is fixedly installed in the discharge port 42 to block the discharge port 42. When stirring and processing are required, the motor 19 is started to drive the screw rod 16 to rotate. Since the stirrer 47 is fixedly connected to the screw rod 16, the stirrer 47 is synchronously driven to rotate.

[0034] Then the worker puts cement raw materials and other auxiliary materials (hereinafter simply referred to as cement raw materials) into the material box 15. At this time, the material box 15 is in a lower position, which is convenient for the worker to feed materials, reducing the labor burden of the worker. The cement raw materials are gradually conveyed along the feeding pipe 14 into the mixing drum 40 under the rotation of the screw 16 and finally enter the mixing drum 40 to be stirred by the stirrer 47.

[0035] When there is less cement raw material remaining in the material box 15, the hydraulic cylinder 44 is controlled to extend to rotate the whole device, so that the feeding pipe 14 and the screw 16 change from the downward inclination to the upward inclination state. By using gravity and cooperating with the rotation of the screw 16, the remaining cement raw materials in the material box 15 can also enter the mixing drum 40 for stirring, thus reducing waste.

[0036] The cement raw materials in the material box 15 are likely to adhere to the spiral surface of the screw 16 during the conveying process due to reasons such as moisture absorption. Due to the change in the inclination direction of the screw 16, the cement raw materials originally attached to one side of the spiral surface of the screw 16 will also fall off under the action of gravity, further reducing waste.

[0037] After the cement raw materials are stirred, the hydraulic cylinder 44 is controlled again to keep the discharge port 42 in the vertically downward state. The operator opens the sealing plug 43, and the cement raw materials fall and are collected. The two conical mixing drums 40 make the cement in the mixing drum 40 tend to converge towards the discharge port 42. At this time, the stirrer 47 continues to rotate, and the stirrer 47 with opposite spiral directions at both ends can also converge the cement raw materials towards the center at this time, thus accelerating the discharge speed and improving the processing efficiency.
