Detailed Description

The following detailed description of the embodiments of the present invention is made with reference to the accompanying drawings, so that the technical solution of the present invention can be more easily understood and grasped.

Example (b): referring to fig. 1 and 2, the embodiment provides a dry powder mortar screening device, which includes a base 1, a screening cylinder 2 fixedly mounted on the base 1 through a bracket 22 and having a feed opening at a lower portion of one end, and a lifter 3 arranged on the base 1 for lifting materials, and specifically, a bucket lifter 3 widely used in the market can be adopted; the screening cylinder 2 is of a semi-cylindrical structure with an open upper part and a screen hole 21 on the lower cylinder wall; a rotating shaft (for view angle reasons, not shown in the figure) which is coaxial with the screening cylinder 2 is rotatably connected in the screening cylinder 2; the rotating shaft is fixedly connected with a helical blade 4, wherein the rotating shaft is in transmission connection with a first motor 5 fixedly arranged at the end part of the screening cylinder 2; the base 1 is fixedly connected with a guide plate 6 which is obliquely arranged through a support leg 61, wherein the guide plate 6 is positioned below all the sieve holes 21; a conveying mechanism 7 is arranged below the material guide plate 6, and the material guided out through the material outlet is conveyed to the side close to the elevator 3 through the conveying mechanism 7.

Through the setting, dry powder mortar material transmits screening section of thick bamboo 2 back through lifting machine 3, under the effect of rotatory helical blade 4, the material can constantly be followed screening section of thick bamboo 2 axial and is advanced, the material just can be sieved by sieve mesh 21 on screening section of thick bamboo 2 lower wall at this in-process, the large granule impurity that remains finally can be by the continuous play of feed opening, it is thus visible at this in-process, do not need the artificial shut down to clear up large granule thing impurity hereinafter for short impurity, these impurity can flow from the feed opening automatically, so the continuity of screening work has been ensured, screening efficiency has been improved. The discharged impurities can be conveyed to the side close to the elevator 3 by arranging the conveying mechanism 7, so that workers can conveniently shovel the impurities into the elevator 3 again for secondary screening; if the transfer mechanism 7 is not provided, it takes a lot of labor for workers to transfer the fallen foreign matters from one end of the classifying drum 2 to one end close to the elevator 3, which increases the amount of labor.

The conveying mechanism 7 comprises a frame 71 fixedly mounted on the base 1, a conveyor belt 72 horizontally arranged on the frame 71 and extending along the axial direction of the sieving cylinder 2, and a second motor 73 in transmission connection with the conveyor belt 72, wherein one end of the conveyor belt 72 is positioned right below the feed opening. The conveying belt 72 is mainly driven by a driving roller and a driven roller (not shown in the figure for the reason of viewing angle), and the driving roller is driven by a motor to rotate, so as to ensure the conveying of the conveying belt 72. The foreign matter thus falls onto the conveyor 72 and is conveyed by the conveyor 72 to the side close to the elevator 3.

As shown in fig. 3, the lower portion of the frame 71 is provided with the scraper 8 perpendicular to the lower surface of the conveyor belt 72 via the connecting member 9, wherein the upper end of the scraper 8 abuts against the lower surface of the conveyor belt 72. The scraper 8 is provided to clean the belt surface of the conveyor belt 72, and the conveyor belt 72 continuously rubs against the upper end of the scraper 8 during the conveying process, so that the dry powder and other substances attached to the conveyor belt 72 can be scraped off.

As shown in fig. 4, the connecting assembly 9 includes U-shaped connecting plates 91 fixedly installed on both sides of the lower portion of the frame 71; a socket 911 for the scraper 8 to vertically and movably pass through is formed in the middle of the horizontal plate part of the connecting plate 91; a locking bolt 92 is further screwed to the connecting plate 91, wherein the inner end of the locking bolt 92 abuts against the side wall of the scraper 8. Because scraper blade 8 and conveyer belt 72 constantly rub, wearing and tearing can constantly appear in scraper blade 8's upper end, in case wearing and tearing are too big, just can't conflict conveyer belt 72 in scraper blade 8 upper end to can't carry out the work of scraping clearly, so, can loosen locking bolt 92 this moment, upwards pull up a bit with scraper blade 8, make scraper blade 8 conflict conveyer belt 72 once more, finally screw locking bolt 92 can.

Referring to fig. 5, in order to prevent the dry powder from staying on the material guiding plate 6, a vibration motor 62 is fixedly installed on the lower wall of the material guiding plate 6, so that the vibration motor 62 drives the material guiding plate 6 to vibrate, and the dry powder is difficult to stay on the material guiding plate 6.

The implementation principle is as follows: the material is put into the material inlet hopper of the hoister 3, lifted by the hoister 3 and finally falls into the screening cylinder 2 from the material outlet of the hoister 3, under the action of the rotating helical blade 4, the material can continuously move forward along the axial direction of the screening cylinder 2, and the material can be screened and filtered by the sieve pores 21 on the lower wall of the screening cylinder 2 in the process, so that the screened dry powder can directly fall onto the material guide plate 6 through the sieve pores 21 and then is led out by the material guide plate 6; the residual large-particle impurities are continuously discharged from the discharge opening and finally fall onto the conveyor belt 72, and the impurities are returned to the side close to the elevator 3 by the conveyor belt 72 so as to be conveniently shoveled into the elevator 3 again.

Above only the typical example of the utility model discloses, in addition, the utility model discloses can also have other multiple concrete implementation manners, all adopt the technical scheme that equivalent replacement or equivalent transform formed, all fall in the utility model discloses the scope of claiming.
