[0002] Alkali residue is an industrial waste residue generated in the process of ammonia-soda process for alkali production, and can be effectively applied to engineering construction as alkali residue-based backfill material to solve land occupation and environmental pollution problems. Some research has been carried out on the basic physical, mechanical properties and static characteristics of alkali residue.

[0003] During the preparation of the alkali residue-based backfill material, the prior art patent publication No. CN104926244B is often used to prepare the alkali residue-based backfill material, in which the alkali residue is pre-pressed to obtain a pre-pressed piece.

[0004] The pre-pressing machine is used to pre-press the alkali residue to obtain the pre-pressed piece, but the pre-pressing machine has the following defects when feeding and discharging the piece (the feeding and discharging of the piece includes feeding and discharging, the feeding is to feed the alkali residue into the pre-pressing machine, and the discharging is to discharge the pre-pressed piece obtained after pre-pressing):

[0005] 1. The pre-pressing machine is generally used to put the alkali residue in the punch one by one by hand feeding method, so there are some dangers, and the accuracy of the alkali residue feeding cannot be guaranteed when hand feeding, and the performance of the alkali residue after pre-pressing is often not good.

[0006] 2. After the alkali residue is pre-pressed, the operator generally takes the pre-pressed piece on the punch by hand and puts it in the storage tank one by one, which increases the task amount of the operator and is time-consuming and laborious. SUMMARY

[0007] To solve the defects in the prior art, the present application provides a method and device for alkali residue-based backfill material pretreatment, which belongs to the technical field of alkali residue-based backfill material pretreatment, and includes a base of a pre-pressing machine, a feeding part and a pre-pressing part.

Here, the base is a hollow structure, one side of which is provided with a connecting opening, the inner surface of the front surface of the connecting opening is provided with a limiting opening, and the two side walls of the connecting opening are uniformly provided with conveying openings in the horizontal longitudinal direction. The base is mirror-imaged in the horizontal longitudinal direction with the connecting opening as the center, and the driving opening is mirror-imaged in the vertical direction along the horizontal transverse direction. The inner surface of the driving opening is uniformly mirror-imaged in the vertical direction along the horizontal transverse direction, and the stop opening is communicated with the driving opening through the arc-shaped guide opening. The combination of other structures and methods effectively avoids the defects that the accuracy of the alkali residue feeding cannot be guaranteed when hand feeding, the performance of the alkali residue after pre-pressing is often not good, the task amount of the operator is increased, and it is time-consuming and laborious.

[0008] The application applies the technical solutions as follows.

[0009] A pretreatment method for alkali residue-based backfill material, comprising:

[0010] S1, the operator drives the ratchet lever into the base via the traction bar, and the ratchet lever assists the ratchet disc to pull the rotating roller and the lead screw to perform rotation, so as to change the vertical position of the hollow chamber via the inner thread hole combined with the lead screw. After the change is completed, the operator rotates the traction bar to make the traction bar rotate the marking bar. The traction bar can be stopped via the assistance of the marking bar and the stop port. In this way, the traction bar is stopped constantly via the assistance of the arch-shaped guide port and the marking bar.

[0011] S2, the operator places the alkali residue to be pre-pressed on the conveying piece one by one. The conveying piece pulls the chain plates on both sides to run inward synchronously under the weight of the alkali residue, and assists the bearing rollers.

[0012] S3, the stepping motor is started. The stepping motor pulls the conveying roller to perform intermittent rotation from right to left. The conveying roller assists the chain plate two to make the power piece move the alkali residue on the top of the base to the right. The hydraulic piston one is started synchronously. The hydraulic piston one assists the right-angle folding ruler-shaped sheet body to perform barrier stopping on the alkali residue.

[0013] S4, the hydraulic piston two is started. The hydraulic piston two pulls the lower pressing plate to perform vertical reciprocating movement, so that the lower pressing plate assists the feeding part to perform pre-pressing treatment on the alkali residue. After the pre-pressing is formed, the hydraulic piston two pulls the lower pressing plate to run upward. At this time, the bearing piece pulls the running piece to run upward under the operation of the hydraulic piston two. The running piece assists the running stick to pull the power bar to run to one side via the power port. The power bar pulls the cross beam to run to one side in the strip-shaped guide port via the attached guide port during the running to one side. When the cross beam runs to the end of the strip-shaped guide port, the cross beam assists the power-driven bar to send out the pre-pressed piece pre-pressed on the base and into the conveying port. The cross beam presses the lock piece two to both sides synchronously. The lock piece two performs stopping on the cross beam under the driving of the lock piece two. The cross beam runs into the arch-shaped guide port. In this way, the cross beam performs rotating movement from right to left in the arch-shaped guide port via the power bar. When the cross beam runs to the leftmost side of the arch-shaped guide port, the cross beam pulls the power-driven bar to return. The cross beam presses the lock piece one to both sides synchronously. The lock piece one performs stopping on the cross beam under the driving of the tension spring rod one.

[0014] S5, the pre-pressed piece pre-pressed is dropped to the inner surface of the bottom of the receiving tank under the driving of the discharging device. The upper part of the alkali residue is attached to the reinforcing piece. The hydraulic piston three drives the pre-pressed piece to the right one by one via the driving block. The pre-pressed piece is attached to the inner surface of the separating piece. Then, the operator can take down the separating piece and take out the pre-pressed piece.
