Detailed Description
The following describes in further detail embodiments of the present invention.
As shown in fig. 1 to 3, the utility model provides an anti-sticking knife gate valve for feed bin discharge port. The silo (not shown) comprises an opening below the silo, and a valve body 10, a horizontally arranged plate-shaped valve plate 12 and a driving device are arranged below the opening of the silo. The driving device drives the valve plate 12 to move horizontally back and forth to close or open the opening of the silo. The valve plate 12 includes a front end and a rear end, and the forward direction is the front end and the reverse direction is the rear end when the valve plate is closed. The valve body 10 is a square structure matching with the shape of the opening of the storage bin, and is composed of a front panel, a rear panel (not shown) and two side panels (not shown). The edge of the valve plate 12 slides on the two side plates, a channel steel with an inward opening can be used as the two side plates, and the valve plate 12 slides in the channel of the channel steel. Other non-negative groove structures can be adopted to avoid the accumulation of materials in the groove to form blockage. For example, the edges of the two sides of the valve plate 12 are provided with sliding grooves from front to back, the side plates are provided with guide rods, and the guide rods are arranged in the sliding grooves of the valve plate 12, so that the valve plate 12 can be guided to slide, materials can be prevented from being accumulated, and grooves of various forms are blocked, and jamming is caused. The above-described structure is not shown in detail since it is not the innovation of the present invention and can be designed by those skilled in the art according to the above requirements. Of course, the two side plates of the valve body 10 may be realized by other components without any structure for vertically limiting the valve plate 12.
A plurality of longitudinal support strips 14 are horizontally arranged on the valve body 10, and a plurality of block-shaped guide pressing blocks 16 are horizontally arranged above the support strips 14 at intervals; the carrier strip 14 is arranged in the direction of movement of the valve plate 12. The valve plate 12 is disposed between the supporting strip 14 and the guiding pressing block 16, the guiding pressing block 16 provides a limit for the valve plate 12 to force the valve plate to cling to the supporting strip 14 when moving, and the front end of the valve plate 12 is provided with a slope 18 which inclines upwards from the front end to the rear end. This allows the valve plate 12 to scrape material off the carrier strip 14 as it moves, avoiding clogging. The guide pressing blocks 16 are arranged at intervals, so that the phenomenon that a gap is formed between the guide pressing block 16 and the supporting strip 14 to cause material overstocking and hinder the movement of the valve plate 12 can be avoided.
A plurality of static pressing blocks 20 are arranged on the front panel of the valve body 10 close to the front end of the valve plate 12, and inclined planes matched with the shape of the valve plate 12 are arranged on the static pressing blocks 20. The end of travel of the valve plate 12 is adjusted until it contacts the static pressure mass 20. At the end of the stroke, the inclined surface of the static pressure block 20 is just in surface contact with the inclined surface 18 of the valve plate 12, so that the valve plate 12 is forced to be downwards tightly attached to the supporting strip 14, the stability of the valve plate 12 is ensured, and good sealing is formed.
The valve body 10 near the rear end of the valve plate 12 is provided with a scraper 22 abutting against the valve plate 12, and the scraper 22 scrapes materials adhered to the valve plate 12 when the valve plate 12 moves backwards. The scraper 22 may be a square metal plate that is bolted vertically downward to the valve body 10 with its lower bottom edge contacting or slightly above the valve plate 12 to scrape material off the valve plate 12 as it retracts.
Further, the guide pressing blocks 16 are disposed on both sides of the valve plate 12 and abut against the valve plate 12, thereby providing a stable limit. The guide pressure piece 16 is provided with a guide slope 24 on the side facing the rear end.
In the first embodiment of the present invention, the driving device adopts the following structure: a support 26 is arranged on one side close to the rear end of the valve plate 12, a screw 28 is arranged in the support 26, the screw 28 is connected with the valve plate 12, a driving sleeve 30 with internal threads is sleeved on the screw 28, and a motor or a handle 32 drives the driving sleeve 30 to rotate, so that the screw 28 is driven by the threads of the driving sleeve 30 to move back and forth.
Of course, the driving device may be a cylinder or a cylinder for driving the valve plate 12 to move back and forth, or other common driving devices (not shown).
Furthermore, the guide pressure piece 16 can be fixed to the valve body 10 by a vertically arranged spring 36. The spring 36 elastically presses the guide pressing block 16 against the valve plate 12, so that the valve plate 12 can be pressed against the supporting strip 14, and a certain avoidance space can be provided.
The utility model discloses when using, through drive arrangement with the valve plate 12 backward movement of feed bin opening below to open the feed bin. During the movement of the valve plate 12, the scraper 22 cleans and scrapes the material on the valve plate 12, and the material in the bin is discharged. When the discharge is required to be stopped, the valve plate 12 is closed through the reverse movement of the driving device; the guide pressing block 16 limits the valve plate 12 to enable the valve plate to move along the supporting strip 14, and the inclined surface 18 of the valve plate 12 can shovel materials on the supporting strip 14; finally, the inclined surface 18 abuts against the static pressure block 20 and is pressed by the inclined surface of the static pressure block 20 so as to abut against the supporting strip 14 to form a seal.
In the first embodiment, the guide mass 16 is a hard stop for the valve plate 12, which is prone to wear of the guide mass 16 or improper spacing to increase resistance to movement of the valve plate 12. To this end, as shown in fig. 3, the present invention also provides a second embodiment: a cylindrical protective cover 34 with an opening at the lower part is adopted, the protective cover 34 is fixedly arranged on the valve body 10, a spring 36 is arranged in the protective cover 34, the guide pressing block 16 is movably arranged at the free end of the spring 36, the shapes of inner holes of the guide pressing block 16 and the protective cover 34 are matched, and a small gap (less than or equal to 1 mm) is formed between the inner holes and the inner wall of the guide pressing block 16. This configuration prevents material from entering the interior of shield 34 and interfering with the operation of spring 36. The spring 36 supports the guide pressing block 16 to make it move backwards to a certain extent, so as to solve the problem of too large resistance when the valve plate 12 moves, and at the same time, the elastic force is used to drive the guide pressing block 16 to abut against the valve plate 12, so as to ensure the position limitation of the valve plate 12.
The above embodiment is only one embodiment of the present invention, and the description thereof is specific and detailed, but not construed as limiting the scope of the present invention. It should be noted that, for those skilled in the art, without departing from the spirit of the present invention, several variations and modifications can be made, which are within the scope of the present invention. Therefore, the protection scope of the present invention should be subject to the appended claims.
