[0027] An easy-to-clean double-roll crusher provided by an embodiment of the present utility model can clean the surface of the crushing rolls in real time during the process of the crushing rolls processing crushed materials. After crushing is completed, a nozzle that sprays high-temperature gas can be used to dry the surface of the crushing rolls, which is beneficial to simplifying the maintenance work of the crushing rolls. In order to realize the structural functions of the mechanism, the mechanism is provided here to include a frame 1 and two relatively arranged crushing rolls 2 rotatably arranged on the frame 1. A driving mechanism 3 for driving the two rolls to rotate relative to each other and a spray drying mechanism for cleaning the surface of the crushing rolls 2 are also provided on the frame 1. The function of the spray drying mechanism is configured to be able to spray liquid onto the surface of the crushing rolls 2 to clean the surface of the crushing rolls 2, and is configured to be able to spray high-temperature gas onto the surface of the crushing rolls 2 to achieve accelerated drying of the surface of the crushing rolls 2 after wet cleaning. During the process of rotating with the crushing rolls 2, the system will automatically realize the all-round automatic cleaning and drying of the surface of the crushing rolls 2. The maintenance process is simple and it is not easy to affect the normal operation of the crushing rolls 2 during the crushing process. In order to simplify the setting of the spray drying mechanism, the spray drying mechanism is provided here to include a plurality of two-fluid nozzles 5 and a heating pipe 8. Specifically, an air inlet pipe 6 and a liquid inlet pipe 7 are respectively provided on each two-fluid nozzle 5. The high-speed ejection of the liquid is achieved through the confluence of the liquid and the gas, and the water consumption can be saved at the same time. The air inlet pipe 6 is connected and communicated with the heating pipe 8, so that the heating pipe 8 can be used to heat the high-pressure gas introduced into the air inlet pipe 6 to achieve heating and drying of the surface of the crushing rolls 2 with high temperature after the work of the crushing rolls 2 is completed. At this time, it is not appropriate to introduce liquid to avoid rewetting, so a control valve 9 is provided on the liquid inlet pipe 7 to control the on-off of the liquid path. At this time, each two-fluid nozzle 5 should be close to or directly point to the surface position of the crushing rolls 2. When only air needs to be introduced into the two-fluid nozzle 5, the control valve 9 is closed and the heating pipe 8 is opened (the heating pipe 8 is usually in the closed state), and only high-pressure gas is introduced.

[0028] An easy-to-clean double-roll crusher provided by an embodiment of the present utility model, in order to simplify the setting of the pipeline and avoid the need to set a corresponding valve body control for each two-fluid nozzle 5, the liquid inlet pipe 7 can be provided here to include a main liquid inlet pipe 701 and a plurality of branch liquid inlet pipes 702 connected and communicated with the main liquid inlet pipe 701, as Figure 1 shown, the liquid inlet path of each two-fluid nozzle 5 is connected and communicated with the corresponding branch liquid inlet pipe 702. The air inlet pipe 6 includes a main air inlet pipe 601 and a plurality of branch air inlet pipes 602 connected and communicated with the main air inlet pipe 601. The air inlet path of each two-fluid nozzle 5 is connected and communicated with the corresponding branch air inlet pipe 602. By controlling the pressure balance of each branch pipeline, the uniform spraying of a plurality of two-fluid nozzles 5 is finally realized.

[0029] An easy-to-clean double-roll crusher provided by an embodiment of the present utility model. In order to simplify the arrangement of the heating pipe 8 so that heat can be evenly distributed to each branch pipeline, the heating pipe 8 can be arranged in the intake direction of the main fluid part of the main intake pipe 601. Similarly, the control valve 9 is arranged in the liquid intake direction of the main fluid part of the main liquid inlet pipe 701 to control the on-off of all branch liquids.

[0030] An easy-to-clean double-roll crusher provided by an embodiment of the present utility model. In order to facilitate the installation of the heating pipe 8 to achieve the gas heating function, the heating pipe 8 can be set to include a pipe body 801. Specifically, as Figure 5 shown, the cross-section of the pipe body 801 is C-shaped, and a sealing plate 802 is slidably arranged on the opening side of the C-shaped pipe body 801. A plurality of heating wires 803 electrically connected to the circuit system are provided on the sealing plate 802. The sealing plate 802 can form a gas flow path in the inner cavity of the pipe body 801 through sliding insertion. At this time, the end of the pipe body 801 can be sealed through the cooperation of the edge connection pipeline and the sealing strip. Through the design of the above structure, the heating wire 803 and the sealing plate 802 are detachable relative to the pipe body 801, which is convenient for adjusting the power according to the actual use situation and also convenient for disassembly, inspection and replacement. The heating wire 803 is preferably composed of a plurality of annular metal wires.

[0031] An easy-to-clean double-roll crusher provided by an embodiment of the present utility model. In order to facilitate the recycling of the sprayed liquid or avoid its impact on the surrounding working environment, a waste liquid recovery box 10 is provided at the bottom of the two crushing rolls 2 to prevent problems such as water accumulation caused by waste liquid.

[0032] An easy-to-clean double-roll crusher provided by an embodiment of the present utility model. In order to separate the waste liquid from the broken waste gas products, a waste filter basket 11 is provided on the top of the waste liquid recovery box 10. In order to efficiently separate the waste liquid from the waste products, the waste filter basket 11 can be set to include a first plate body 1101 and a second plate body 1102. The first plate body 1101 is provided with hollow mesh holes and is inclined with the horizontal plane. The second plate body 1102 is arranged on one side where the bottom surface of the first plate body 1101 is located. By forming a space angle, on the one hand, the waste can be accumulated at the corner for easy cleaning, and on the other hand, the waste liquid is easy to seep out from the bottom corner points. In order to prevent liquid accumulation at the corner points, a gap can be provided between the second plate body 1102 and the first plate body 1101 so that the accumulated liquid can be discharged from this gap position.

[0033] The above are only the preferred embodiments of the present utility model. It should be noted that for those of ordinary skill in the art, without departing from the technical principle of the present utility model, several improvements and deformations can be made, and these improvements and deformations should also be regarded as the protection scope of the present utility model.
