AI Technical Summary
Existing impeller airlocks are prone to clogging or jamming when conveying large-volume materials, causing the blades to stop rotating or even damaging the equipment. At the same time, materials with high hardness can cause the blades to rub violently against the inner wall of the casing, resulting in damage.
A hinged plate and an elastic telescopic component are installed in the impeller airlock. Centrifugal force is used to unfold the hinged plate to separate the material into sections, and the elastic telescopic component buffers the severe impact and friction forces, preventing the material from getting stuck on the blades and reducing friction damage.
It effectively prevents material blockage and jamming, reduces damage to blades and casing, and improves equipment stability and service life.

[0026] Embodiment 1, please refer to Figures 1 to 4The utility model discloses a kind of anti-blocking and anti-sticking blade of impeller air lock, including shaft joint plate 1 and hinged plate 2, by hinged plate 2 being hinged and installed in one end of shaft joint plate 1, let hinged plate 2 unfold and carry out segmentation separation to material when blade rotates in shell due to the action of centrifugal force, when material is stuck in hinged plate 2 and inner wall of shell, hinged plate 2 will rotate with shaft joint plate 1 hinged end as shaft to make material pass, to avoid material to be stuck with blade;By installing elastic expansion component 102 on shaft joint plate 1 and hinged plate 2, two ends of elastic expansion component 102 are respectively hinged in first hinged seat 101 on the surface of shaft joint plate 1 and second hinged seat 201 on the surface of hinged plate 2, when hinged plate 2 contacts to the material block of greater hardness, it will rotate with shaft joint plate 1 hinged end as axis and extrude elastic expansion component 102, to buffer violent impact force and friction force, to avoid material to cause damage to blade and inner wall of shell.
[0027] Specifically, one end of the shaft joint plate 1 is fixedly installed on the adapter shaft, the hinged plate 2 is hinged at the end of the shaft joint plate 1 away from the adapter shaft, a first hinged seat 101 is fixedly arranged on one side of the shaft joint plate 1, a second hinged seat 201 is fixedly arranged on one side of the hinged plate 2 close to the first hinged seat 101, an elastic expansion component 102 is hinged on the first hinged seat 101, and one end of the elastic expansion component 102 away from the first hinged seat 101 is hinged on the second hinged seat 201.
[0028] Further, the elastic expansion component 102 includes a telescopic rod 102a, a telescopic cylinder 102b and a telescopic cylinder bottom cover 102c, one end of the telescopic cylinder 102b is closed and the other end is open, the telescopic cylinder bottom cover 102c is fixedly installed at the open end of the telescopic cylinder 102b, one end of the telescopic cylinder bottom cover 102c away from the telescopic cylinder 102b is hinged on the first hinged seat 101, the telescopic rod 102a penetrates through the closed end of the telescopic cylinder 102b, one end of the telescopic rod 102a is fixedly provided with a sliding cap edge 102a-1, the sliding cap edge 102a-1 is slidingly sleeved in the telescopic cylinder 102b, one end of the telescopic rod 102a away from the sliding cap edge 102a-1 is hinged on the second hinged seat 201, and a reset spring 102d is sleeved in the telescopic cylinder 102b, one end of the reset spring 102d close to the telescopic cylinder bottom cover 102c is fixedly connected with the telescopic cylinder bottom cover 102c, when one end of the hinged plate 2 contacts the material block of greater hardness, the hinged plate 2 rotates and extrudes the telescopic rod 102a, the sliding cap edge 102a-1 at one end of the telescopic rod 102a extrudes the reset spring 102d, so as to buffer the impact force of collision with the material, and avoid the collision damage of the material to the blade and the inner wall of the shell.
[0029] Furthermore, a limiting angle edge 103 is fixedly provided on the end face of the shaft connecting plate 1 near the end face that is hinged to the hinge plate 2. The limiting angle edge 103 has an inclined surface on the side of the shaft connecting plate 1 near the side where the first hinge seat 101 is fixed. The inclined surface of the limiting angle edge 103 faces the side of the shaft connecting plate 1 where the first hinge seat 101 is fixed, so that the hinge plate 2 forms an angle with the hinge surface of the shaft connecting plate 1 when it is in the unfolded state, which facilitates the compression of the elastic telescopic component 102 when it comes into contact with hard materials.
[0030] Furthermore, it also includes a one-way discharge plate 104. The shaft plate 1 has a discharge channel 104a on the side of the first hinge seat 101 away from the hinge plate 2. The one-way discharge plate 104 covers the discharge channel 104a. One end of the one-way discharge plate 104 is hinged to the first hinge seat 101. When the blade rotates past the discharge port, there is material inside that has not been discharged. The one-way discharge plate 104 opens to allow the material to be discharged from the discharge through hole 104a.
[0031] The operation process in this embodiment is as follows:
[0032] When the airlock is activated, the shaft plate 1 rotates around the pivot shaft and, under the action of centrifugal force, the hinge plate 2 unfolds, thereby conveying the material entering the airlock in segments. When a large or hard material block enters the airlock, one end of the hinge plate 2 will rotate and squeeze the elastic telescopic component 102 when it contacts the material block, so that the material block can pass through and prevent blockage. At the same time, it buffers the impact force generated when it collides with the material block, reducing damage to the blades and the inner wall of the casing. After the material block passes through, the elastic telescopic component 102 resets the hinge plate 2 and continues to convey the incoming material in segments.
[0033] Example 2, please refer to Figures 1 to 5 Based on embodiment 1, it also includes a sleeve plate 202, which is slidably sleeved on one end of the hinge plate 2. When a material with a large volume or high hardness enters the airlock, the sleeve plate 202 will retract to allow the material block to pass through, further preventing the material block from being stuck by the blades.
[0034] Specifically, a sliding groove 202a is provided on one side of the sleeve plate 202, and the end of the hinge plate 2 away from the hinge end with the shaft plate 1 is slidably sleeved in the sliding groove 202a.
[0035] Furthermore, a spring plate 202b is sleeved inside the sliding groove 202a. The two ends of the spring plate 202b are connected to the bottom of the sliding groove 202a and the cross-section of the hinge plate 2, respectively. When the material block passes through, the spring plate 202b resets the sleeve plate 202.
[0036] Furthermore, roller hinge seats 202c are fixed on both sides of the side of the sleeve plate 202 away from the hinge plate 2, and rollers 202d are rotatably installed on the roller hinge seats 202c on both sides. When the blade edge and the inner wall of the machine casing are stuck by the material block, the rotation of the roller 202d facilitates the sliding of the sleeve plate 202 to facilitate the passage of the material block.
[0037] The operation process in this embodiment is as follows:
[0038] When a large or hard material block is between the blade and the inner wall of the machine casing, the rotating roller 202d rotates, causing the sleeve plate 202 to squeeze the spring plate 202b, which causes the sleeve plate 202 to slide, making the gap between one end of the sleeve plate 202 and the inner wall of the machine casing larger, thus facilitating the passage of the material block and preventing the material block from getting stuck.
