Description

Wet sand coating and adding device in ductile cast iron pipe

Technical Field

The utility model belongs to the technical field of cast pipe production, and particularly relates to a wet sand coating and sand adding device in a nodular cast iron pipe.

Background

In the production process of the cast pipe, cement mortar needs to be coated on the inner wall of the pipe, and wet sand is used in the production process of a company due to the high price of the dry sand, but the flowability of the wet sand is far lower than that of the dry sand.

Based on the poor flowability of wet sand, when manual work is cheap in the past, the manual work is mainly adopted to add sand into a vibrating screen to feed a bucket elevator behind the vibrating screen. Along with the increase of company's output, production efficiency promotes, and annual production time increases, and several disadvantages are highlighted to artifical reinforced mode: the labor intensity of workers is high, the feeding capacity is insufficient, and the production requirements cannot be met. However, if engineering machinery is used for direct feeding, the vibrating screen has no time to screen and feed, and meanwhile, mechanical operation easily causes too much sand loaded by the vibrating screen, the vibrating screen is overloaded, and the motor is overloaded and tripped.

SUMMERY OF THE UTILITY MODEL

In order to solve the problems, the utility model provides a wet sand adding device for a nodular cast iron pipe, which can improve the sand adding efficiency and reduce the labor intensity of sand adding operation.

The specific technical scheme of the utility model is as follows: the device is of a double-layer hopper structure and comprises a feeding hopper and a discharging hopper, wherein the feeding hopper is fixedly installed through an upright post, the discharging hopper is fixed below the upper hopper through a screw rod, the feeding hopper and the discharging hopper are not in contact, a rubber spring and a matched nut are installed on the screw rod, a vibrating motor is installed on the lateral side of the discharging hopper, and an adjusting flashboard is arranged at the bottom of the discharging hopper. When the vibrating motor is used, the vibrating motor can overcome the weight of the sand hopper below the lower part to generate larger amplitude by only needing smaller exciting force, so that wet sand falls.

Furthermore, be provided with short stand in the hopper down, can drive the inside husky motion of hopper down, play and break up the effect.

Furthermore, a vibration groove is formed below the discharging hopper, sand enters the bucket elevator through a discharging opening in the front of the vibration groove, and the bucket elevator conveys the sand to the sand tank.

Compared with the prior art, the utility model has the advantages that:

1) the double-layer hopper structure is simple in structure and convenient to use, solves the problem of sand adding efficiency, reduces the labor intensity of sand adding operation, and effectively ensures the capacity improvement of the whole production line.

2) The rubber spring is used between the upper and lower hoppers of the utility model, instead of a common metal spring, so that the structure is compact, the bearing capacity is large, the equipment can run stably, and the running noise is low.

3) According to the utility model, the vibrating motor is arranged on the blanking hopper, and after the vibrating motor is amplified by the rubber spring, the larger amplitude can be generated by overcoming the weight of the sand hopper below the lower part only by a smaller exciting force, so that wet sand falls.

Detailed Description

The utility model is further described below with reference to the accompanying drawings.

As shown in fig. 1-2, the device for adding wet sand in the ductile iron pipe is of a double-layer hopper structure and comprises an upper hopper 2 and a lower hopper 10. The feeding hopper 2 is fixedly installed through the stand column 1, the feeding hopper 10 is fixed below the feeding hopper 2 through the screw rod 5, the feeding hopper and the feeding hopper are not in contact, the screw rod 5 is provided with the rubber spring 3 and the matched nut 4, the vibrating motor 9 is installed on the side of the feeding hopper 10, and the bottom of the feeding hopper is provided with the adjusting flashboard 6. Due to the amplification effect of the rubber spring 3, the vibration motor 9 can overcome the weight of the sand hopper below the lower part to generate larger amplitude by only needing smaller exciting force when in use, so that the wet sand falls.

The short upright columns are arranged in the lower hopper 10, so that sand in the lower hopper 10 can be driven to move, the sand scattering effect is achieved, and the sand is convenient to discharge.

A vibration groove 11 is arranged below the lower hopper 10, sand enters the bucket elevator 7 through a feed opening in the front of the vibration groove 11, and the bucket elevator 7 conveys the sand to the sand tank 8. The sand feeding amount of the lower vibration groove 11 is adjusted by using an adjusting gate 6 at the bottom of the sand hopper, and the sand feeding amount of the vibration groove is controlled, so that the sand feeding capacity of the following bucket elevator 7 is matched.

In use, the loader loads sand into the upper hopper 2, which first fills the lower hopper 10 under the action of gravity. The upper hopper 2 and the lower hopper 10 are connected together through a rubber spring 3, a nut 4 and a screw rod 5. When vibrating motor 9 starts, form the decurrent effort that makes progress, enlarge the back through rubber spring 3, only need less drive power, just can drive down hopper 10 vibration from top to bottom, and hopper 10 internally mounted has a short stand down, is convenient for drive inside sand motion, supplementary sand discharge.

The sand is discharged from the bottom of the blanking hopper 10 and falls onto the vibration groove 11, the sand inlet flow of the vibration groove 11 is adjusted by adjusting the opening of the flashboard 6, the sand moves forward along with the vibration of the vibration groove 11 and enters the bucket elevator 7 through the blanking port at the front part, and finally the sand is conveyed into the sand tank 8 by the bucket elevator 7, so that the sand adding operation is completed.

Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the utility model, the scope of which is defined in the appended claims and their equivalents.
