Description

Technical Field

[0001] The utility model relates to the technical field of roller presses, in particular to a raw material roller press. Background Art

[0002] Raw material roller pressing is a process for making cement. Raw materials such as limestone and clay are mixed and processed through a roller press to make them into powdery substances, which are then sent to a kiln for firing to finally obtain cement products. The roller press will generate a certain amount of heat during operation. In order to ensure the normal operation of the equipment and extend its service life, it is necessary to cool it down. At present, when the roller press is in use, the heat is passively dissipated through the roller, and the heat dissipation efficiency is low, which can easily lead to accelerated aging of the extrusion roller and shorten its service life. Utility Model Content

[0003] The utility model provides a raw material roller press, which solves the above-mentioned technical problems.

[0004] The utility model solves the above-mentioned technical problems as follows:

[0005] A raw material roller press comprises a machine body, an extrusion roller, a heat exchange roller and a feed outlet, wherein a support column is provided at the bottom end of the machine body, an extrusion roller is rotatably installed inside the machine body, a heat exchange roller is rotatably installed on one side of the extrusion roller in the machine body, a heat exchange tube is provided in the heat exchange roller, a brush is provided in the machine body below the extrusion roller, a feed outlet is provided at the bottom end of the machine body, and a material guide trough is provided at the top end of the machine body.

[0006] The beneficial effect of the utility model is that when in use, the user guides the raw material into the machine body through the material guide trough and squeezes it through the squeezing roller. At the same time, the heat exchange roller is cooled by the refrigerant in the heat exchange tube, and because the heat exchange roller and the squeezing roller are in contact and transmission, the heat of the squeezing roller is transferred to the heat exchange roller, and the heat of the squeezing roller is taken out by the refrigerant in the heat exchange roller, thereby achieving the effect of continuously cooling the squeezing roller.

[0007] On the basis of the above technical solution, the present invention can also be improved as follows.

[0008] Furthermore, a transmission wheel is provided at one end of the squeezing roller, which is located outside the machine body, and the squeezing roller is transmission-connected to an external power source via the transmission wheel.

[0009] The beneficial effect of adopting the above further solution is that it is convenient to drive the squeezing roller to work through an external power source.

[0010] Furthermore, the material guide trough is coaxial with the symmetry axis of the extrusion roller.

[0011] The beneficial effect of adopting the above further solution is that it is convenient to guide the raw material through the material guide groove, so that the raw material can be easily squeezed through the squeezing roller.

[0012] Furthermore, there are two squeezing rollers in total, and the two squeezing rollers are symmetrically distributed in the machine body.

[0013] The beneficial effect of adopting the above further solution is that it is convenient to dissipate heat for the two squeezing rollers at the same time.

[0014] Furthermore, the heat exchange roller is connected to the refrigerant through a heat exchange tube.

[0015] The beneficial effect of adopting the above further solution is that it is easy to dissipate the heat conducted from the squeezing roller to the heat exchange roller.
