Description
Technical Field
The invention relates to the field of hopper cleaning, in particular to a hopper cleaning tool and a hopper cleaning method.
Background
The titanium alloy consumable electrode is formed by mixing and pressing massive alloy raw materials. Before massive alloy raw materials mix, different types of alloy raw materials are loaded in different feed boxes, a hopper is arranged below a discharge hole of the feed box, a mixing device is arranged below the hopper, when mixing is needed, the discharge hole of the feed box is opened, different raw materials in different feed boxes enter the hopper together and enter the mixing device downwards along the hopper, and the mixing device mixes the raw materials.
When the alloy raw material flows downwards in the hopper, the surface of the alloy raw material collides with, contacts and rubs with the inner wall of the hopper, so that dust and powder of the alloy raw material are adhered to the inner wall of the hopper. When different types of titanium alloys are pressed, the titanium alloys of different types need to be mixed by alloy raw materials with different component proportions, so that the inner wall of the hopper needs to be cleaned in order to avoid the influence of dust and powder adhered on the inner wall of the hopper on the pressed purity of the titanium alloys.
With reference to fig. 1, the existing hopper 1 is conical (four side walls of the hopper 1 are all obliquely arranged, the four side walls of the hopper 1 are mutually close from top to bottom), the hopper 1 is deeper, and the depth can reach 2-5m. At present, the cleaning mode of the hopper 1 is as follows: the alcohol is poured into the inner wall of the hopper 1, then the inner wall is manually scrubbed, arms cannot touch the deeper part of the hopper 1, the alcohol can only be poured into the inner wall of the hopper 1, the alcohol flows downwards, the deeper side wall cannot be scrubbed, and therefore the inner wall cleaning effect of the deeper part of the hopper is poor. Meanwhile, the hopper is large in size, four sides are required to be scrubbed manually in sequence during scrubbing, the operation is troublesome, and the workload is large.
Disclosure of Invention
The invention aims to provide a hopper cleaning tool and a hopper cleaning method so as to realize more sufficient scrubbing of the inner side wall of a hopper.
In order to achieve the above purpose, the invention adopts the following technical scheme: the hopper cleaning tool comprises at least three scrubbing units, wherein the plurality of scrubbing units are connected end to end in sequence to form a polygon;
The scrubbing units comprise expansion plates and scrubbing cloth, the scrubbing cloth is positioned on the front surface of the expansion plates, two ends of the scrubbing cloth are fixedly connected to two ends of the expansion plates, and the scrubbing cloth has elasticity;
The expansion plate comprises a first sliding plate and a second sliding plate which are transversely connected in a sliding manner; an elastic piece which enables the expansion plate to have an elongation trend is connected between the first sliding plate and the second sliding plate.
The principle and the advantages of the scheme are as follows: the scrubbing units in this scheme are a plurality of, and a plurality of scrubbing units connect gradually into the polygon end to can adapt to with the shape of hopper, with the hopper wash the frock put into the hopper in like this after, every scrubbing unit can be relative with the inner wall of hopper, thereby scrubbing corresponding hopper inner wall.
After the hopper cleaning tool is placed into the hopper, the scrubbing cloth is positioned on the front surface (the front surface is the surface opposite to the inner wall of the hopper) of the expansion plate, so that the scrubbing cloth is attached to the inner wall of the hopper, and when the hopper cleaning tool moves vertically, the scrubbing cloth wipes on the inner wall of the hopper, so that the inner wall of the hopper is scrubbed.
The expansion plate in this scheme is arranged in supporting the cloth of scrubbing, and when scrubbing the cloth and the contact of hopper inner wall, the expansion plate is located the rear of scrubbing the cloth (scrubbing the one side that the cloth kept away from the hopper inner wall) and supports the cloth of scrubbing, guarantees that the cloth of scrubbing can not retreat, guarantees that the cloth of scrubbing can fully contact with the hopper. The expansion plate in this scheme can stretch out and draw back, through the relative lateral sliding of first sliding plate and second sliding plate to realized the expansion plate flexible, like this when hopper washs the frock when the downhill movement in the hopper, because the lateral wall of hopper is close to each other gradually, consequently the expansion plate can shorten automatically under the restriction effect of hopper inner wall, and the hopper washs the frock volume and becomes automatic diminishing, thereby adapts to the lateral wall of hopper and is close to each other's condition gradually, guarantees that the hopper washs the frock can normal downwardly moving. Because the scrubbing cloth has elasticity, after the expansion plate is shortened, the scrubbing cloth is adaptively contracted under the action of self elasticity. When the expansion plate is shortened, the elastic piece is extruded by the first sliding plate and the second sliding plate.
When the hopper cleaning tool moves upwards in the hopper, the side walls of the hopper are gradually far away from each other, so that the expansion plate automatically stretches under the action of the elastic piece, the volume of the hopper cleaning tool is automatically increased, the condition that the side walls of the hopper are gradually far away from each other from bottom to top is adapted, and when the hopper cleaning tool moves upwards, the volume of the hopper cleaning tool can be correspondingly increased to scrub the inner wall of the hopper. Because the scrubbing cloth has elasticity, when the expansion plate is lengthened, the scrubbing cloth is deformed and lengthened, and the scrubbing length of the scrubbing cloth is correspondingly increased.
In summary, the hopper cleaning tool disclosed by the application can adapt to the shape of a hopper when moving in the hopper, the volume can be correspondingly reduced when moving from top to bottom, and the volume can be correspondingly increased when moving from bottom to top, so that the hopper can be cleaned in all directions. When hopper washs the inside wall of hopper, can clean all inside walls of hopper simultaneously, can also clean the depths of hopper simultaneously, compare the mode of manual scrubbing, improved the efficiency of scrubbing, the effect that the hopper was cleaned is better.
