Description

[Detailed explanation of the idea]

0001

[Industrial application field]

The present invention relates to a base material protection plate for protecting the base material, especially when solid materials etc. As a base material protection plate to prevent material from adhering to the surface when moving over the surface. related.

0002

[Conventional technology]

Traditionally, solid materials such as ore, coke, crushed stone, cement, and chemicals are processed using vibrating feeders. , when moving over the surface of the base material such as in transfer paths, hoppers, etc., due to the moisture content of solid materials. To protect the base material by preventing it from adhering to the base material or abrasion of the base material due to collisions. A base material protection plate made of an elastic material such as rubber is used. For example, vibration Only the both ends of the rubber-like elastic body stretched along the inner peripheral wall of the chute part of the player are restrained. By bundling and installing, secondary vibrations induced in the elastic body and deformation due to elasticity are reduced. This prevents material from adhering to the chute and allows the material to flow down smoothly. is known (Utility Model Application Publication No. 164220/1983).

0003

[Problem that the idea aims to solve]

However, the conventional configuration described above has problems with vibrating feeders in which the chute vibrates. This is advantageous in that it prevents wear on the surface of the base material when the solid material moves through the chute. However, as the dimension between both side walls of the chute increases, the rubber-like elasticity Install by stretching the body along the inner peripheral wall of the chute and restraining only both ends. This increases the difficulty of the work and causes irregular deformation of the rubber-like elastic body. This makes it difficult to move smoothly when solid materials containing water are moved. This is not desirable as it may be blocked. Therefore, the present invention can simplify the installation work even if the base material becomes large, and To provide a base material protection plate that can smoothly move a water-containing solid material without causing adhesion. With the goal.

0004

[Means to solve the problem]

The present invention protects the base material when a hydrated solid material moves over the surface of the base material. This is a base material protection plate for use when the substrate placed on the base material has multiple almost identical openings. are arranged side by side and have an edge around the opening, and an elastic material is placed on this substrate. The vibrating body is constructed by attaching a plate-shaped vibrating body made of material to the edge portion with adhesive.

[0005]

[Effect]

In the above method, since the vibrating body has a flat plate shape and is unitized, it is possible to The installation work can be done easily, and the deformation of the vibrating body corresponds to the opening. This results in regular vibrational displacement of the planar membrane in the exposed area, preventing the movement of the hydrated solid material. This can be done smoothly without causing problems.

[0006] Here, regarding prevention of adhesion of water-containing solid materials, it is important to In some cases, the flat vibrating body is glued to the edge of the board so that the part corresponding to the opening can vibrate. When the vibrating body begins to move and the moving fixed material, which contains moisture, starts to adhere to the vibrating body. By increasing the mass of the solid material attached to the attached part, the vibration displacement of the planar membrane of the vibrating body can be further reduced. This causes the inertia of the solid material to exceed the adhesion force between the solid material and the vibrating body. In the above case, the force equilibrium is no longer maintained and the attached solid material vibrates. The solid material is peeled off from the body surface and becomes a smooth surface, and the solid material continues to move smoothly on the vibrating body surface. Since the material can be moved, it is possible to protect it from adhesion to the base material.

[0007] In addition, if the base material is a stationary member, the solid material may not adhere to the vibrating body. When the vibration starts, the vibration body flattens due to collisions of solid materials and irregular increases in attached mass. This causes the planar membrane to vibrate, and as mentioned above, it peels off from the vibrating body surface. , it has a smooth surface that allows for smooth movement and prevents adhesion to the base material. can be protected.

[0008]

【Example】

An embodiment of the present invention will be described below with reference to the drawings. In Figures 1 to 3, 1 indicates a base material protection plate, and the base material is used to protect base material 2. 2 mounted on the surface. The base material protection plate 1 has a plate-shaped vibrating body 3 stretched over a substrate 4. The substrate 4 is made of carbon steel, etc., and has almost the same shape (for example, A plurality of openings 6 having rectangular dimensions are arranged in parallel, and the periphery of the opening 6 is An edge 5 is provided to surround the edge 5, and a button is provided at a predetermined interval on the edge 5. A root hole 8 is provided.

[0009] The vibrating body 3 is made of an elastic material such as rubber or polyurethane, and has approximately the same external shape as the substrate 4. It is a plate-like object having an outer shape of the same dimensions as the one shown in FIG. It is tensioned using suitable means and formed integrally. Furthermore, the vibrating body 3 has the base A bolt hole 7 is provided corresponding to the bolt hole 8 of the plate 4, and the bolt hole 7 is connected to the motherboard through the bolt 9. The material protection plate 1 is attached on the surface of the base material 2. Flat member with vibrating base material 2 An example of a case consisting of a vibrating sieve chute (not shown) I can do it.

0010 In addition, as shown in the figure, for example, when the base material 2 is composed of a stationary flat plate-like member, There is no solid material hopper chute etc. In either case, when the solid material is moved over the surface of the base material 2, , adhesion occurs when the solid material has a specific moisture content.

[0011] When the base material 2 is a vibrating member, the solid material is the vibrating body 3 of the base material protection plate 1. Move by jumping on the surface. At this time, mechanical properties such as bending strength of the vibrating body 3 Therefore, even if the vibrating force in the base material 2 acts on the vibrating body 3, the opening 6 in the substrate 4 is not affected. There is virtually no deformation in the corresponding parts and the solid material can be moved smoothly.

0012 Then, when a solid material is transferred under a specific moisture content, the solid material at said moisture content is The material may exhibit significant adhesion and harden as it moves over the surface of the vibrating body 3. Attachment of body materials begins and sequential growth occurs to increase the attached mass. A vibrational displacement of the planar membrane of the vibrating body 3 is generated in a portion corresponding to the opening 6. Furthermore, as the adhesion mass increases due to adhesion growth, the vibration displacement of the vibrating body 3 increases. In combination with the vibration of the base material 2, the attached mass of the solid material and the vibration of the base material 2 are increased. The overall inertial force due to the movement increases, and this inertial force is greater than the adhesion force between the solid material and the vibrating body 3. When it reaches the top, the force equilibrium between the two is no longer maintained, so the attached The solid material is peeled off from the surface of the vibrating body 3 and presents a smooth surface with no adhesion. As a result, the solid material can continue to move smoothly on the surface of the vibrating body 3, and is transferred to the base material 2. The above-mentioned operation can be repeated.

[0013] In addition, when the base material 2 is a stationary member, the solid material moves on the surface of the vibrating body 3. When the solid material starts to adhere to the surface of the vibrating body 3 during movement, irregularities in the adhered mass of the solid material may occur. In conjunction with the increase in the force and the impact, the flatness of the vibrating body 3 at the part corresponding to the opening 6 decreases. A vibrational displacement of the planar membrane is generated. Furthermore, the increase in adhesion mass due to adhesion growth progresses. When the vibration is expanded, the vibration displacement of the vibrating body 3 increases, and the inertial force due to the attached mass of the solid material increases. Due to this inertial force, the attached solid material is peeled off from the surface of the vibrating body 3. As a result, the solid material can continue to move smoothly to the surface of the vibrating body 3, and its attachment to the base material 2 is prevented. It can be protected from wear and abrasion, and the above-described operations can be repeated.

[0014] When the base material protection plate 1 is installed on the surface of the base material 2, the base material protection plate 1 has an appropriate width and width. Since it is manufactured in a unit type with different length and length dimensions, multiple The base material protection plate 1 can be arranged and installed in a mosaic pattern, and the dimensions of the base material 2 can be Even if it is relatively large, it can be easily installed without any particular difficulty. , Moreover, the vibration displacement of the entire vibrating body 3 consisting of the plurality of base material protection plates 1 arranged is This is done reliably over the entire installation area, so the solid material covers the entire surface of the vibrating body 3. You can move smoothly across the board. In addition, the base material protection plate 1 prevents the material from moving. It can be easily applied to equipment, etc. that are prone to adhesion when exposed to water.

[0015]

[Effect of the idea]

As explained above, according to the base material protection plate of the present invention, the vibrating body has a flat plate shape and the unit Since it is knitted, it can be easily attached to the base material even if the size of the base material increases. I can. In addition, the deformation of the vibrating body causes a regular vibrational displacement of a plane membrane in the part corresponding to the opening. Therefore, it is possible to smoothly move the water-containing solid material without causing adhesion. Wear.

[0016] Moreover, if solid material adheres to the surface of the vibrating body of the base material protection plate, the vibrating body Since the vibration characteristics are used for peeling, the base material can be preserved without using a complicated structure. can be protected.
