Description

Technical Field

[0001] The utility model relates to a device for preventing material blocking of a chute of a covering material feeding system, belonging to the technical field of electrolytic aluminum production. Background Art

[0002] The covering material system has a chute from the bottom of the silo to the telescopic nozzle. During normal use, the silo discharges materials through the chute, and the materials at the telescopic nozzle enter the multi-functional overhead crane silo. When the material fluidity is poor, the viscosity of the material may cause the material to flow poorly in the chute, which in turn causes material blockage. Material blockage not only affects the normal operation of the production line, but also brings additional safety hazards. In order to clear the blockage, the operator is usually required to manually clear it. This process is not only time-consuming and labor-intensive, but also requires the operator to perform high-altitude operations, which undoubtedly increases the risk and difficulty of the operation. Utility Model Content

[0003] In view of the above deficiencies in the prior art, the technical problem to be solved by the utility model is to provide a device for preventing material blocking in the chute of a covering material feeding system to prevent material blocking in the chute due to poor material fluidity.

[0004] The utility model discloses a chute anti-blocking device for a covering material unloading system, wherein at least one sliding frame is provided on the chute, and the sliding frame can slide back and forth along the length direction of the chute, and the sliding frame connects two vertical scrapers, and the scrapers are attached to the inner wall of the chute on the left and the right, and a steel wire is provided between the bottom ends of the two scrapers.

[0005] Preferably, the distance between the scraper and the inner wall of the chute is 5 mm; the distance between the steel wire and the bottom of the chute is 5 mm.

[0006] Preferably, slide rails are provided on both sides of the chute, slide blocks are provided on the slide rails, and the slide frames are fixedly connected to the slide blocks.

[0007] Preferably, the sliding frame is a rectangular metal frame.

[0008] Preferably, there are two sliding frames, the distance between the two sliding frames is half the length of the chute, and the bottoms of the two sliding frames are connected by a connecting plate.

[0009] Preferably, the bottom surface of the connecting plate is provided with a hanging ear, and the hanging ear is connected to a traction rope, so that a worker on the ground can drive the sliding frame to slide back and forth by pulling the traction rope.

[0010] Preferably, limit screws are provided at both the front and rear ends of the slide rail to prevent derailment.

[0011] In order to solve the problem of material blockage, the utility model installs a sliding frame in the middle part of the chute. When the material is blocked, the sliding frame is pulled, and the scraper and steel wire cut and disturb the material in the chute, thereby improving the fluidity of the material, reducing the labor force of personnel, avoiding high-altitude operations and improving the inherent safety.

[0012] Compared with the prior art, the utility model has the following beneficial effects:

[0013] The anti-blocking device for the chute of the covering material unloading system described in the utility model is equipped with a sliding frame, a scraper and a steel wire. When the chute is blocked due to poor material fluidity, workers do not need to manually clear or climb. They only need to pull the traction rope on the ground to make the sliding frame slide on the chute, and the scraper and steel wire can cut and disturb the material, thereby improving the fluidity of the material and solving the problem of material blocking. This greatly reduces the manpower and time required for clearing the blockage and improves production efficiency.

[0014] Secondly, since manual unblocking and climbing operations are avoided, the utility model significantly reduces the operation risk and improves the safety of the production line. Workers do not need to be exposed to possible safety risk environments, reducing the probability of accidents.

[0015] In addition, the design of the utility model is simple and practical, and components such as the sliding frame, the scraper and the steel wire are easy to install and maintain, and the cost is relatively low. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] like Figures 1 to 3 As shown, this embodiment is implemented by the following technical solution: two sliding frames 2 are provided on the chute 1, and the distance between the two sliding frames 2 is half the length of the chute 1, so that the pulling distance can be shortened, that is, there is no need to pull the entire length of the chute. The sliding frame 2 is a rectangular metal frame, and the bottoms of the two sliding frames 2 are connected by a connecting plate 8.

[0024] Slide rails 5 are provided on both sides of the chute 1, and sliders 6 are provided on the slide rails 5. Limit screws 7 are provided at the front and rear ends of the slide rails 5. The slide frame 2 is fixedly connected to the sliders 6. The slide frame 2 can slide back and forth along the length direction of the chute 1. The slide frame 2 is connected to two vertical scrapers 3. The scrapers 3 are attached to the inner wall of the chute 1 on the left and right, and a steel wire 4 is provided between the bottom ends of the two scrapers 3.

[0025] The distance between the scraper 3 and the inner wall of the chute 1 is 5 mm; the distance between the steel wire 4 and the bottom of the chute 1 is 5 mm.

[0026] In this embodiment, a hook 9 is provided on the bottom surface of the connecting plate 8 , and the hook 9 is connected to a traction rope 10 .

[0027] When material is blocked, workers on the ground pull the traction rope to drive the sliding frame to slide back and forth. The scraper and steel wire cut and disturb the material in the chute, which improves material fluidity, reduces labor, avoids high-altitude operations, and improves inherent safety.

[0028] In addition, the utility model can also be electrified to drive the sliding frame or the slider to reciprocate through a lead screw or a crank slider mechanism; furthermore, the chute can also be provided with a silo wall vibrator to increase the vibration effect of the chute and improve the fluidity of the material.
