Description

Technical Field

[0001] The utility model belongs to the technical field of air locks, and particularly relates to an air lock with an adjustable arc plate to prevent blocking. Background Art

[0002] In the process of using the air lock, in order to prevent the material from getting stuck between the free end of the impeller blade and the inner wall of the shell due to its large volume, causing the air lock to be blocked, the arc plate is usually designed to be adjustable. Although the existing adjustable arc plate anti-blocking air lock can meet the basic needs of anti-blocking, the arc plate is only reset by a spring. Therefore, after a period of use, the device will fail to rebound normally due to the failure of the spring, which makes the arc plate unable to reset normally, and thus cannot fully meet people's use needs.

[0003] For example, the utility model with publication number CN 209177583 U discloses an adjustable arc plate anti-blocking air shutoff. In the technical solution of this patent, arc plates are symmetrically arranged on the inner wall of the shell and are arranged on both sides of the impeller. One end of each arc plate is connected to the upper end of the shell, and the other end is connected to the lower end of the shell through a spring. The spring generates an elastic force that makes the arc plate close to the impeller and coaxial with the impeller. Since the technical solution of this patent only uses the spring to reset the arc plate after bending adjustment, the spring may fail to rebound normally due to bending deformation and other faults after a period of use, which makes the arc plate unable to reset normally after bending deformation, thereby affecting the normal operation of the air shutoff. Utility Model Content

[0004] In view of this, the utility model aims to solve the shortcomings of the prior art and provide an adjustable arc plate to prevent air shutoff from being blocked. Not only can the bending adjustment of the arc plate prevent the material from being stuck between the free end of the impeller blade and the inner wall of the shell due to its large volume, thereby causing blockage of the air shutoff, but also the arc plate can be smoothly reset through the reset auxiliary structure, thereby fully meeting people's usage needs.

[0005] In order to solve the above technical problems, the technical solution adopted by the utility model is: an adjustable arc plate anti-blocking air lock, comprising a shell, a feed port is arranged at the top of the shell, a discharge port is arranged at the bottom of the shell, arc plates are arranged at the left and right side ends of the shell, the upper ends of the two arc plates are respectively provided with fixing plates, the two fixing plates are respectively provided with fixing bolts which are screwed and fixed to the inner wall of the shell, and the shell is provided with threaded fixing holes which are matched with the fixing bolts, a front baffle is detachably arranged at the front side end of the shell, a driving motor is transversely arranged at the rear side end of the shell through a fixing frame, a connecting shaft extending to the inside of the shell is arranged on the output shaft of the driving motor through a coupling, a plurality of blades which are matched with the arc plates are arranged on the connecting shaft, a clearance groove which is matched with the lower end of the corresponding arc plate is arranged at the left and right side ends of the shell, an extension plate is respectively arranged at the lower ends of the two arc plates, a plurality of telescopic push rods whose output shafts extend to the clearance groove are respectively arranged at the left and right side ends of the shell, and the ends of the output shafts of the plurality of telescopic push rods on the same side are jointly provided with a limiting push plate which is matched with the extension plate. The driving motor is a reduction motor.

[0006] As a further improvement of the utility model, the front baffle is fixed to the shell by clamping, and the shell is provided with a taking and placing hole adapted to the front baffle. The front baffle is also provided with connecting bolts for threadedly fixing to the shell, and the shell is provided with threaded connecting holes adapted to the connecting bolts.

[0007] As a further improvement of the utility model, a handle is also provided on the front baffle.

[0008] As a further improvement of the utility model, a bearing seat is further provided on the inner side wall of the front baffle plate, and the inner side wall is clamped and fixed to the front side end of the connecting shaft.

[0009] As a further improvement of the utility model, a plurality of mounting slots are provided on the connecting shaft, and the inner ends of the plurality of blades are respectively fixed with the corresponding mounting slots. The plurality of mounting slots are also respectively provided with mounting bolts for threadedly fixing the blades, and the blades are provided with threaded mounting holes matching the mounting bolts.

[0010] As a further improvement of the utility model, a fastening cylinder which is clamped and fixed with the output shaft of the telescopic push rod is provided on the limiting push plate, and a fastening bolt which is used to threadably fix the output shaft of the telescopic push rod is provided on the fastening cylinder, and a threaded fastening hole which is compatible with the fastening bolt is provided on the output shaft of the telescopic push rod.

[0011] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0012] Firstly, when the material is stuck between the free end of the impeller blade and the inner wall of the casing due to its large volume, thereby causing the air shutoff to be blocked, it is only necessary to shorten the output shafts of the telescopic push rods on both sides by a certain length, move the two limit push plates outward, and release the support limit on the two arc plates. The arc plates can then automatically move toward the outer shape under the driving action of the stuck material and the blades, allowing the material to flow smoothly and avoid clogging the air shutoff. Thereafter, the output shafts of the telescopic push rods on both sides are extended by a certain length again, allowing the limit push plates to move inward, thereby allowing the two arc plates to move inward again and reset, and allowing the limit push plates to contact and fix the extension plates, thereby preventing the arc plates from independently deviating until the next time the material is easily stuck between the free end of the impeller blade and the inner wall of the casing.

[0013] Secondly, the front baffle and the shell can be flexibly fixed by simply clamping and fixing the front baffle with the pick-up and release hole, and then passing the connecting bolt through the side wall of the front baffle and screwing it with the threaded connecting hole; the blade and the connecting shaft can be flexibly fixed by simply clamping and fixing the inner end of the blade with the mounting slot, and then passing the mounting bolt through the side wall of the mounting slot and screwing it with the threaded mounting hole.

[0014] Thirdly, the front end of the connecting shaft can be rotationally supported by the bearing seat, so that the connecting shaft can rotate smoothly.

[0015] Fourthly, the output shaft of the telescopic push rod and the limit push plate can be detachably fixed by only clamping the fastening cylinder and the output shaft of the telescopic push rod, and then passing the fastening bolt through the side wall of the fastening cylinder and screwing it to the threaded fastening hole.

The driving motor 108 is a reduction motor.

[0024] like Figure 1 , 2As shown in , 4, the front baffle 107 is fixed with the shell 101, and the shell 101 is provided with a taking and placing hole 115 adapted to the front baffle 107. The front baffle 107 is also provided with a connecting bolt 116 for screwing and fixing with the shell 101, and the shell 101 is provided with a threaded connecting hole adapted to the connecting bolt 116.

[0025] like Figure 3 As shown, the inner side wall of the front baffle 107 is also provided with a bearing seat 118 that is fixedly connected to the front end of the connecting shaft 109. Through the bearing seat 118, the front end of the connecting shaft 109 can be rotatably supported, so that the connecting shaft 109 can rotate stably.
