Description

Technical Field

[0001] The utility model relates to the technical field of mortar processing, in particular to a feeding device for mortar processing. Background Art

[0002] At present, in order to improve the quality of mortar processing, researchers in related fields have developed a variety of improvement schemes for the feeding device for mortar processing. For example, the authorized patent with announcement number CN218398841U proposes "the mortar processing feeding device, by arranging a vibrating screen on the inner wall of the storage box to vibrate and screen the sand, and by tilting the vibrating screen, the blocked stones are moved to one end of the collecting pipe, and the stones and impurities are transmitted to the inner wall of the screening cylinder through the collecting pipe, so as to screen the sand and automatically collect the stones and impurities contained in the sand. , which solves the problem that during the mortar feeding process, the gravel contained in the sand will also enter the processing cylinder together, thus affecting the quality of the finished mortar product. "The mortar processing feeding device, by starting the motor, makes the screening cylinder rotate, and the gravel collected on the inner wall of the screening cylinder collides with the inner wall of the screening cylinder due to the influence of centrifugal force, so that the sand on the gravel is separated due to the effect of the collision and re-enters the storage box through the feeding pipe arranged at the bottom, so as to achieve the effect of saving materials and solve the problem that some sand particles are blocked by adhering to the surface of the gravel, resulting in a waste of some materials."

[0003] However, from the perspective of actual production on site, the applicant found several problems that contradict the actual production. First, the two screening methods of vibration and centrifugal screening can screen out the gravel and the sand on the surface of the gravel, but the construction period is long and the steps are complicated. The more critical problem is that the gravel in the sand material that can enter the on-site production is not large and small. A separate process is set up only for the sand adhering to the surface of a small amount of gravel, and the value is not proportional to the cost.

[0004] Second, it is known from the further disclosed contents in the specification of the above-mentioned prior art that the screened gravel needs to be manually cleaned and collected, which further reduces the efficiency of the overall process and increases the labor intensity of the staff.

[0034] Working principle:

[0035] Embodiment 1

[0036] Without setting the L-shaped stirring plate 10, the sand material to be used is added into the interior of the composite filter cylinder 4 through the feed pipe. After completion, the sealing cover is locked and closed on the top of the feed pipe. Then, the servo motor 7 is started, and the output end of the servo motor 7 drives the composite filter cylinder 4 and the sand material inside the composite filter cylinder 4 to rotate synchronously through the composite transmission shaft 5, thereby utilizing the centrifugal rotation effect and the filtering effect of the filter screen 42 to filter the qualified sand material into the annular space between the feed box 1 and the composite filter cylinder 4;

[0037] After all the sand inside the composite filter cylinder 4 has been filtered, the sand pump 2 is started, and the sand pump 2 pumps the sand into the designated container through the connecting pipe 9. After the sand is sucked, the hydraulic rod 8 in the open state is closed, and then the output end of the hydraulic rod 8 drives the combined sealing component 6 to automatically move downward, making way for the bottom space of the composite filter cylinder 4 and the feeding box 1, and then the stones filtered out of the composite filter cylinder 4 flow out of the feeding box 1, achieving the effect of automatically conveying and cleaning the filtered impurities.

[0038] Embodiment 2

[0039] An L-shaped stirring plate 10 is provided, and the sand material to be used is added into the interior of the composite filter cylinder 4 through the feed pipe. After completion, the sealing cover is locked and closed on the top of the feed pipe. Then, the servo motor 7 is started, and the output end of the servo motor 7 drives the composite filter cylinder 4, the L-shaped stirring plate 10 and the sand material inside the composite filter cylinder 4 to rotate synchronously through the composite transmission shaft 5, thereby utilizing the centrifugal rotation effect and the filtering effect of the filter screen 42 to filter the qualified sand material into the annular space between the feed box 1 and the composite filter cylinder 4;

[0040] At the same time, the rotating L-shaped stirring plate 10 will perform secondary dispersion and stirring on the sand material in the annular space between the feeding box 1 and the composite filter cylinder 4, thus providing favorable conditions for the smooth pumping of the subsequent sand pump 2;

[0041] After all the sand materials inside the composite filter cylinder 4 have been filtered, the sand pump 2 is started, and the sand pump 2 pumps the sand materials into the designated container through the connecting pipe 9. At the same time, the servo motor 7 is kept in the working state, so that the composite filter cylinder 4 and the L-shaped stirring plate 10 continue to rotate, thereby providing an auxiliary material-pickling effect for the pumping of the sand pump 2, and accelerating the speed at which the sand materials in the annular space between the feeding box 1 and the composite filter cylinder 4 enter the connecting pipe 9. After the sand materials are sucked, the hydraulic rod 8 in the open state is closed, and then the output end of the hydraulic rod 8 drives the combined closing component 6 to automatically move downward, making way for the bottom space of the composite filter cylinder 4 and the feeding box 1, and then allowing the stones filtered out of the composite filter cylinder 4 to flow out of the feeding box 1, thereby achieving the effect of automatically conveying and cleaning the filtered impurities.
