Description

Technical Field

[0001] The invention belongs to the technical field of pretreatment of alkali slag-based backfill materials, and in particular relates to a method and a device for pretreatment of alkali slag-based backfill materials. Background Art

[0002] Alkali slag is the industrial waste residue produced in the process of making alkali by the ammonia-alkali method. Its application in engineering construction as alkali slag-based backfill material can effectively solve the problems of land occupation and environmental pollution. Some research work has been carried out on the basic physical, mechanical properties and static characteristics of alkali slag.

[0003] During the preparation of alkali slag-based backfill materials, the prior art solution with patent publication number "CN104926244B" is often used to prepare the alkali slag-based backfill materials, wherein the alkali slag is pre-pressed to obtain a pre-pressed part.

[0004] To pre-press the alkali slag to obtain pre-pressed parts, a pre-pressing machine must be used. However, the current pre-pressing machine has the following defects when performing input and output (input and output include input and output, input is to feed the alkali slag into the pre-pressing machine, and output is to send the pre-pressed parts obtained after pre-pressing):

[0005] 1. When the pre-pressing machine is currently feeding in and out of the parts, the alkali slag is generally placed in the punch press one by one by hand, so there are some risks, and the accuracy of the alkali slag feeding cannot be guaranteed when feeding by hand, which is often not suitable for the performance of the alkali slag pre-pressing;

[0006] 2. After the alkali slag is pre-pressed, the operator basically takes the pre-pressed parts on the punch press by hand and places them one by one in the storage tank. This method increases the workload of the operator and is time-consuming and labor-intensive. Summary of the invention

[0007] In order to solve the defects existing in the prior art, the present invention proposes a method and device for pretreating alkali slag-based backfill materials, which belongs to the technical field of pretreating alkali slag-based backfill materials. The method and device include a base, a feeding part and a prepressing part of a prepressing machine. The feeding part is arranged on one side of the top of the base, and the prepressing part is arranged on the other side of the top of the base. Here: the base is a hollow structure, one side of which is provided with a connecting port, the inner surface of the front of the connecting port is provided with a limiting port, and the two side walls of the connecting port are evenly provided with transmission ports in the horizontal vertical upward direction, a driving port is mirrored in the horizontal vertical upward direction with the connecting port as the center in the base, and a stop port is mirrored in the vertical upward direction evenly on the inner surface of the driving port along the horizontal and horizontal directions, and the stop port is communicated with the driving port via an arched ring guide port; combined with other structures and methods, the method effectively avoids the defects of the prior art that the accuracy of alkali slag feeding cannot be guaranteed when feeding by hand, the performance is often not suitable for prepressing after alkali slag, the workload of the operator is increased, and it is time-consuming and labor-intensive.

[0008] The present invention utilizes the following technical solutions.

[0009] A method for pretreating alkali slag-based backfill materials, comprising:

[0010] S1, the operator drives the ratchet rod toward the base through the traction bar, so that the ratchet rod assists the ratchet disc to pull the rotating roller and the lead screw to rotate, so as to change the vertical position of the hollow chamber through the inner thread mouth of the lead screw. After the change is completed, the operator rotates the traction bar, so that the traction bar pulls the marking bar to rotate, and the traction bar can be stopped with the assistance of the marking bar and the stop mouth, so as to assist the marking bar to stop the traction bar through the arch ring guide mouth;

[0011] S2, the operator places the alkali slag to be pre-pressed on the conveying sheet one by one, and the conveying sheet pulls the chain plates on both sides under the weight of the alkali slag to assist the bearing rollers to move inward synchronously;

[0012] S3, start the stepper motor, pull the conveying roller through the stepper motor to perform intermittent rotation from right to left, and the conveying roller assists the chain plate 2 to make the power sheet slide the alkali residue on the top of the base to the right, and synchronously start the hydraulic piston 1, and assist the right-angled ruler-shaped sheet body to perform a blocking stop on the alkali residue through the hydraulic piston 1;

[0013] S4, start the hydraulic piston 2, the hydraulic piston 2 pulls the lower pressure plate to perform vertical back and forth movement, so that the lower pressure plate assists the feeding part to perform pre-pressing treatment on the alkali slag. After the pre-pressing is formed, the hydraulic piston 2 pulls the lower pressure plate to run upward. At this time, the bearing piece pulls the running piece upward under the operation of the hydraulic piston 2, and the running piece assists the running rod to pull the power bar to run to one side through the power port. During the running to one side, the power bar pulls the cross beam through the attached guide port to run to one side in the strip guide port. When the cross beam runs to the end of one side of the strip guide port, the cross beam is pulled to the end of the strip guide port. The beam assists the power drive bar to send out the pre-pressed part formed by the pre-pressing on the base and send it into the conveying port. The synchronous cross beam presses the lock piece 2 toward both sides. The lock piece 2 stops the cross beam under the drive of the lock piece 2, so that the cross beam runs into the arched guide port, thereby pulling the cross beam through the power bar to perform a rotational operation from right to left in the arched guide port. When the cross beam runs to the leftmost side of the arched guide port, the cross beam pulls the power drive bar to restore, and the synchronous cross beam presses the lock piece 1 toward both sides. The lock piece 1 stops the cross beam under the drive of the tension spring rod 1.

[0014] S5, the pre-pressed part formed by pre-pressing falls to the inner surface of the bottom of the storage tank under the drive of the discharge device, and the upper part of the alkali residue sticks to the reinforcement plate. The synchronous hydraulic piston drives the pre-pressed part to the right one by one through the driving block, so that it sticks to the inner surface of the separation plate. Then the operator can take down the separation plate and take out the pre-pressed part.
