Description

Technical Field

[0001] This utility model relates to the field of concrete additive technology, and in particular to a pre-melting device for raw materials used in concrete additives. Background Technology

[0002] In order to improve production efficiency and quality, existing concrete additives usually require the pre-melting of raw materials before production.

[0003] In use, most existing pre-melting devices use a flame tube at the bottom to heat the mixing vessel. However, with the bottom under heating, it is difficult to open a discharge chute at the bottom of the mixing vessel. As a result, the operator needs to remove and turn the mixing vessel over to discharge the pre-melted material inside. However, since the temperature of the mixing vessel is high after heating, the operator's safety is low. Therefore, we propose a pre-melting device for raw materials of concrete additives. Utility Model Content

[0004] The purpose of this invention is to provide a pre-melting device for raw materials used in concrete additives, which solves the existing problems.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A pre-melting device for concrete additive raw materials includes a fixed frame. A first motor is fixedly installed on one side of the fixed frame, and a first drive shaft is fixedly installed at the output end of the first motor. The first drive shaft is rotatably installed inside the fixed frame. A pre-melting kettle for mixed additive raw materials is fixedly installed between the first drive shaft and one side of the fixed frame. Multiple flame-spraying pipes are fixedly installed on the bottom inner wall of the fixed frame. An electric telescopic rod is fixedly installed on one side inner wall of the fixed frame. A baffle is fixedly installed at the output end of the electric telescopic rod. Two guide ramps are fixedly installed on the top inner wall of the pre-melting kettle for mixed additive raw materials.

[0007] As a further improvement to the above solution, the top of the pre-melting kettle for the mixed additive raw materials is fixedly installed with an inlet and outlet pipe, and a sealing plate is installed on the top of the inlet and outlet pipe. Both the sealing plate and the top of the inlet and outlet pipe are provided with multiple threaded holes.

[0008] By adopting the above technical solution, after pre-melting, the first motor can be controlled to drive the first drive shaft and the pre-melting kettle of the mixed additive raw material to rotate, and the electric telescopic rod can drive the baffle to block the flame pipe. The sealing plate can be removed from the top of the inlet and outlet pipes by bolting, so that the pre-melted raw material can be discharged from the inlet and outlet pipes, which is convenient for workers to collect. The guide slope can guide the raw material to prevent the raw material from being left behind.

[0009] As a further improvement to the above solution, a second motor is fixedly installed on the rear side of the pre-melting kettle for the mixed additive raw materials, a second drive shaft is fixedly installed on the output end of the second motor, and multiple stirring rods are fixedly installed on the outer side of the second drive shaft.

[0010] As a further improvement to the above solution, an auxiliary shaft is rotatably mounted on the front side of the pre-melting kettle for the mixed additive raw materials, an mounting plate is fixedly mounted on one side of the pre-melting kettle for the mixed additive raw materials, a rotating shaft is fixedly mounted on the inner side of the mounting plate, and transmission gears are fixedly mounted on the outer sides of the auxiliary shaft, the mounting plate, and the second drive shaft, with adjacent transmission gears meshing with each other.

[0011] As a further improvement to the above solution, a plurality of striking blocks are fixedly installed on the outer side of the rotating shaft, and the striking blocks abut against the pre-melting kettle of the mixed additive raw materials.

[0012] As a further improvement to the above solution, the guide ramp is triangular in shape, and a scraper is provided above the stirring rod.

[0013] By adopting the above technical solution, the scraper can prevent residues from appearing on the inner wall of the pre-melting kettle for the mixed additive raw materials, resulting in better material feeding effect of the device.

[0014] As a further improvement to the above solution, the striking block is made of rubber and is elliptical in shape.

[0015] By adopting the above technical solution, the rotating striking block can strike and vibrate the pre-melting kettle of the mixed additive raw materials, so that the raw materials will not adhere to the upper part of the inner wall during the stirring, pre-melting and feeding of the pre-melting kettle of the mixed additive raw materials.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0017] (1) A pre-melting device for concrete additive raw materials of this utility model adds the concrete additive raw materials to be pre-melted into the inner side of the pre-melting kettle of the mixed additive raw materials through the inlet and outlet pipes, and controls the electric telescopic rod to drive the baffle to move, so that the flame pipe can be leaked out, and the flame pipe can be started to heat the pre-melting kettle of the mixed additive raw materials. After the pre-melting is completed, the first motor can be controlled to drive the first drive shaft and the pre-melting kettle of the mixed additive raw materials to rotate, and the electric telescopic rod can drive the baffle to block the flame pipe. The sealing plate can be taken out from the top of the inlet and outlet pipes through bolts, so that the pre-melted raw materials can be discharged from the inlet and outlet pipes for easy collection by the staff. The guide slope can guide the raw materials to prevent the raw materials from being left behind.

[0018] (2) In the pre-melting device for concrete additive raw materials of this utility model, during the heating and pre-melting process, the second motor can be turned on. The second motor can drive the second drive shaft and multiple stirring rods to rotate. The stirring rods can stir the concrete additive raw materials to prevent the bottom from sticking during the heating process. After the second drive shaft rotates, it can drive the rotating shaft to rotate through the cooperation of the auxiliary shaft and the transmission gear. After the rotating shaft rotates, it can drive multiple striking blocks to rotate. After the striking blocks rotate, they can strike and vibrate the pre-melting kettle of the mixed additive raw materials, so that the raw materials will not stick to the upper part of the inner wall when the pre-melting kettle of the mixed additive raw materials is stirred, pre-melted and fed.
