Description

Maintenance apparatus of sieve screen tension of vibrator

The present invention relates to a screen tension maintaining device for a vibrating body, and more particularly, by vibrating screening materials such as liquids or powders used as chemicals, feed materials, foods, minerals, paper pulp, etc. The present invention relates to a screen tension maintaining device for a vibrating body in which a screen (or “sieve screen”) that is a consumable material is mounted on a vibrator so that the tension of the screen can be maintained in an initial state when used.

1 is a schematic diagram of a vibrating sieve receiving device mounted with a circular sieve.

As shown, the mount 2 on which the drive motor 1 is mounted, the pulley 4 connected to the drive motor 1 via the belt 3 and rotated therebetween, have their own phase differences. Vibrating body (7) vibrating by the rotation of the upper and lower weights (5,6) rotatably mounted on the upper and lower ends of the upper and lower vibrating body base (9) for supporting the vibrating body (7) to the lower frame (8) ) And consumables that are installed in the intermediate frame 11 jointly connected through the band 10 on the lower frame 8 and sort the material passing through the mesh during the driving of the driving motor 1 by particles. It is comprised with the circular sieve 12.

Unexplained reference numeral 13 is an outlet for discharging the material that is not screened out because it does not pass through the mesh of the body 12, 14 is an elastic member for supporting the lower weight (6).

At this time, the phase of the upper weight 5 with respect to the lower weight 6 described above is 0 °, 45 °, 90 °, etc., and is selectively adjusted and used according to the material to be selected.

On the other hand, the above-described upper weight (5) generates a horizontal vibration of the sieve 12 during its rotation to move the material put on the sieve 12 in the rotational direction, the lower weight 6 is rotated thereof As the vertical vibration of the sieve network 12 occurs, the material on the sieve network 12 is moved to the edge.

In the case of manufacturing the sieve mesh used as described above, pull the sieve mesh 12 to the frame side with a manpower or a strap and then fix it with lead, adhesive, bolts, etc. to adjust the tension of the sieve mesh 12, or Inserted between the upper and lower frames of the metal material is pulled by hand and tightened by a bolt to adjust the tension of the net 12.

However, the above-described sieve network 12, as a result of repeatedly screening a predetermined material, as well as the tension of the sieve network 12, as well as the frequent occurrence of the falling portion of the frame and the mesh such as a metal material, during work, Since the damaged network 12 must be replaced from time to time (about 2 to 3 times a day) will have a problem that causes physical, human, and time loss.

In addition, when the screening network 12 is damaged during the operation, the first place in the workplace to replace the first screened by the material selected through the network 12 is uneven, the reliability of the product is reduced, which causes a large loss of the company Will have

In addition, since the above-described screen 12 is a consumable, it is necessary to prepare a separate screen (meaning in stock) at any time during the operation, which increases the economic burden of the user, from the production order of the screen 12 to use It takes a long time, there is a problem that the cost of the cost increases because the price of the network 12 is expensive.

In addition, the work of replacing the above-described screening network 12 during the operation is difficult, and as the working time increases, the workability of replacing the screening network 12 at the work site is greatly reduced, and the waste of human resources when replacing the screening network 12 is reduced. This results in a problem that the screening operation using the sieve network 12 is stopped and its productivity is greatly reduced.

2 is a schematic diagram of a screen tension maintaining apparatus for a vibrating body according to the prior art.

As shown, in the case of fixing the above-described circular sieve 12 to the inside of the intermediate frame 11, the sieve 12 is strongly pulled in the circumferential direction using a tool such as a strapping machine, and then the frame 15 After adhering with an adhesive such as lead or epoxy resin, the sieve 12 is fixed to the inside of the intermediate frame 11 described above.

However, an adhesive such as lead or epoxy resin, which is used to fix the above-described sieve network 12 to the frame 15, is extremely harmful to the human body and thus causes harmful fertilization from the user. Harm, polluting the environment, and the above-described body network 12 is expensive, the user has to suffer the economic burden.

Therefore, an object of the present invention is that it is unnecessary to prepare a screen, which is a consumable material for screening particles, such as liquid or powder, which are used as chemicals, for each particle by vibration, and then attach it to the vibration sieve receiving device. It is to provide a vibrating screen tension maintaining device that can significantly reduce the time, material, labor cost.

Another object of the present invention, when the screen is broken during the work and must be replaced, vibrating screen that can significantly improve the workability to select the material by using the screen quickly installed in the workplace in a short time It is to provide a tension retaining device.

Another object of the present invention is to maintain the screen tension for the vibrating body so that even if the screen is repeatedly selected for a long time, the screen tension is maintained in the initial state, the material to be screened is uniform to greatly improve the reliability of the product To provide a device.

Still another object of the present invention is to provide a screen tension maintaining device for a vibrating body in which the price of the screening net is relatively much lower than that of the conventional screening net so that the price competitiveness can be greatly improved in the industry.

Another object of the present invention, the vibrating screen to prevent the harm to the user or operator without using a substance such as lead or epoxy resin harmful to the human body when fixing the mesh to the frame to maintain the tension of the mesh It is to provide a tension retaining device.

Still another object of the present invention is to generate a lot of dust in the process of polishing lead or epoxy resin when the waste screen is conventionally repaired, and to cause environmental pollution by using toxic substances such as hydrochloric acid when soldering. It is to provide a screen tension maintaining device for the vibrating body to prevent it.
