The equipment currently used for friction cleaning includes: a base frame, an inclined box body is installed on the base frame, a feed port is provided at the lower end of the inclined box body, a discharge port is provided at the upper end of the inclined box body, a rotating conveying shaft is installed in the inclined box body, the rotating conveying shaft is movably supported in the inclined box body, and is driven to rotate by a driving device, and uniformly distributed conveying blades are installed on the rotating conveying shaft, and the conveying blades are at a certain angle on the rotating conveying shaft, and a screen is installed on the outside of the rotating conveying shaft and in the inclined box body. The crushed material after hot cleaning enters the inclined box from the feed port. In the process of conveying the material to the discharge port, the material and the material produce mutual friction. The pollutants separated from the material after friction are separated from the material by the conveying blades and the screen, achieving the effect of friction cleaning. Due to the length limitation of this structure of friction cleaning equipment, the material stays in the equipment for a short time, and the pollutants attached to the surface of the material are not separated in time and are transported to the next equipment together with the material. Therefore, those skilled in the art provide a four-pass friction spray cleaning device to solve the problems raised in the above background technology. Summary of the invention

DETAILED DESCRIPTION

[0011] In order to more clearly illustrate the embodiments of the present invention or the technical solutions in the prior art, the drawings required for use in the embodiments or the description of the prior art will be briefly introduced below. Obviously, the drawings described below are only some embodiments of the present invention. For ordinary technicians in this field, other drawings can be obtained based on these drawings without paying creative labor.

[0012] See Figure 1 —— Figure 3As shown, this specific embodiment adopts the following technical scheme: it comprises a base frame 1, a friction spray device 2, a feed port 3 and a discharge port 4; four groups of parallel and alternately arranged friction spray devices 2 are installed on the base frame 1, each group of friction spray devices 2 forms an angle α of 8~12° with the horizontal plane, a feed port 3 is arranged at the lower end of the friction spray device 2, and a discharge port 4 is arranged at the high end, from the first group of friction spray devices 2 to the last group of friction spray devices 2, the discharge port 4 of the upper group is connected with the feed port 3 of the next group in sequence; the friction spray device 2 comprises an inclined box body 5, a multifunctional rotating shaft 6, a spray port 7, a barrier net 8 and a liquid collecting box 9, a plurality of spray ports 7 are evenly distributed on the top of the inclined box body 5, a multifunctional rotating shaft 6 is installed in the inclined box body 5 through a bearing, the multifunctional rotating shaft 6 is driven to rotate by a driving motor, a barrier net 8 is arranged below the multifunctional rotating shaft 6, a liquid collecting box 9 is installed below the barrier net 8, and a sewage pipe 10 is connected to the bottom of the liquid collecting box 9.

[0013] The multifunctional rotating shaft 6 comprises a rotating main shaft 11, a feeding spiral blade 12, a friction conveying blade 13 and a reverse choke blade 14. The feeding end of the rotating main shaft 11 is provided with a feeding spiral blade 12. A plurality of friction conveying blades 13 and reverse choke blades 14 are evenly distributed on the rotating main shaft 11 on one side of the feeding spiral blade 12. The friction conveying blades 13 and the reverse choke blades 14 are staggered. The feeding spiral blade 12 at the front end of the rotating main shaft 11 is used to convey materials backwards. The friction conveying blade 13 is used to make the materials fully rub against each other while conveying the materials. The reverse choke blade 14 is used to prolong the friction cleaning time of the materials in the inclined box 5.

[0014] The working principle of the present invention is as follows: the material after heat cleaning enters the inclined box 5 from the feed port 3, and under the action of the feed spiral blade 12 on the multifunctional rotating shaft 6, the material is quickly transported to the friction spray area, and under the action of the friction conveying blade 13 on the multifunctional rotating shaft 6, the material is fully rubbed against each other during the process of being transported from the inclined box 5 to the discharge port 4, and the attachments separated from the surface of the material after friction are quickly separated from the material under the action of the spray port 7, and flow into the collecting box 9 through the barrier net 8, and are discharged from the equipment through the sewage pipe 10. Since the multifunctional rotating shaft 6 is provided with a reverse flow-blocking blade 14, the friction cleaning time of the material in the inclined box 5 is increased, and four sets of friction spray devices 2 are installed on the base frame 1, so that the material can be fully friction-cleaned and the pollutants attached to the surface of the material can be more effectively separated.

[0015] The above shows and describes the basic principles and main features of the present invention and the advantages of the present invention. It should be understood by those skilled in the art that the present invention is not limited to the above embodiments. The above embodiments and descriptions are only for explaining the principles of the present invention.
