Description

Technical Field

[0001] This utility model belongs to the technical field of mixing devices, and relates to a grouting material mixing device. Background Technology

[0002] When installing large equipment, the anchor bolt holes and secondary grouting layers require CGM grouting material for grouting. CGM grouting material is typically mixed manually using a drone to stir the bagged grout in buckets. This process is labor-intensive and time-consuming. Furthermore, the quality control of manual mixing is inconsistent, resulting in a short initial setting period for the grout. Since large equipment installations require a large amount of CGM grouting material, the output from manual mixing is insufficient to meet actual on-site requirements. Therefore, this invention provides a grouting material mixing device to address these technical shortcomings. Utility Model Content

[0003] The purpose of this utility model is to address the problems existing in the prior art by providing a grout mixing device, which solves the problems of low mixing efficiency, inconsistent mixing quality, and low grout output caused by manual mixing of grout during the installation of large equipment, making it difficult to meet the actual needs on site.

[0004] Therefore, the present invention adopts the following technical solution:

[0005] A grout mixing device includes a support frame, which is horizontally arranged. A reducer and a motor are provided at the top of the support frame, and a primary silo and a secondary silo are provided at the bottom in sequence. A mixing shaft is provided below the motor, which is vertically arranged and passes through the support frame, the primary silo and the secondary silo in sequence.

[0006] The bottom wall of the primary silo is equipped with a primary discharge valve and the side is equipped with a feeding port; the bottom wall of the secondary silo is equipped with a secondary discharge valve.

[0007] The stirring shaft is provided with a primary stirring paddle on the side wall of the primary silo, and the two are vertically connected; the stirring shaft is provided with a secondary stirring paddle on the side wall of the secondary silo.

[0008] Furthermore, the secondary mixing impeller includes a first impeller blade, which is arranged parallel to the bottom wall of the secondary hopper, and a second impeller blade is provided above it. One end of the second impeller blade is connected to the mixing shaft, and the other end is connected to the middle of the first impeller blade.

[0009] Furthermore, the primary silo is cylindrical.

[0010] Furthermore, the upper section of the secondary silo is a frustum shape with an increasing radius, the middle section is a cylinder, and the lower section is a cone shape with a decreasing radius.

[0011] Furthermore, the reducer and the motor are connected by belt drive.

[0012] Furthermore, the support has several frames on its side, and the two are vertically connected.

[0013] The beneficial effects of this utility model are as follows:

[0014] This utility model of grout has high mixing efficiency, which can meet the actual amount of grout used during the installation of large equipment. Multiple bags of grout can be added and mixed simultaneously according to the actual amount used, which can ensure the mixing quality of grout, accurately control the grout batching, and use mechanical mixing to maintain a constant mixing rate and ensure mixing time. This avoids the problem of using grout before it is fully slurried due to human factors, which would result in a significant reduction in the strength of the grout layer. Attached Figure Description

Detailed Implementation

[0018] The technical solution of this utility model will be described below with reference to the accompanying drawings and implementation methods.

[0019] like Figure 1 and 2 As shown, a grout mixing device includes a support 2, with several frames 1 on the side of the support 2 and the two are vertically connected; the support 2 is horizontally arranged, and a reducer 3 and a motor 5 are provided on its top, and the two are connected by a belt 4.

[0020] The bottom of the support 2 is provided with a primary hopper 7 and a secondary hopper 11. Specifically, the primary hopper 7 is cylindrical; the upper section of the secondary hopper 11 is a frustum with an increasing radius, the middle section is cylindrical, and the lower section is a cone with a decreasing radius.

[0021] The bottom wall of the primary silo 7 is equipped with a primary discharge valve 9 and a feeding port 13 on the side. The bottom wall of the secondary silo 11 is equipped with a secondary discharge valve 12. The stirring shaft 6 is located below the motor 5. The stirring shaft 6 is vertically arranged and passes through the support 2, the primary silo 7 and the secondary silo 11 in sequence.

[0022] The stirring shaft 6 is provided with a primary stirring paddle 8 on the side wall of the primary silo 7, and the two are vertically connected; the stirring shaft 6 is provided with a secondary stirring paddle 10 on the side wall of the secondary silo 11.

[0023] Specifically, the secondary mixing impeller 10 includes a first impeller 10a, which is arranged parallel to the bottom wall of the secondary hopper 11, and a second impeller 10b is provided above it. One end of the second impeller 10b is connected to the mixing shaft 6, and the other end is connected to the middle of the first impeller 10a.

[0024] The usage process of this utility model is as follows:

[0025] First, 25kg / bag of CGM grout is added to the primary silo 7 through the feeding port 13. For each bag of grout added, 3kg of water is added to the primary silo 7. The motor 5 drives the reducer 3 to rotate through the belt 4. The reducer 3 is connected to the mixing shaft 6. The primary mixing paddle 8 performs the initial slurrying of the grout and water in the primary silo 7.

[0026] Secondly, after the initial slurrying is completed, the first-level discharge valve 9 releases the solution to the second-level silo 11. The grouting material after initial slurrying is then stirred a second time in the second-level silo 11 by the second-level stirring paddle 10 to achieve secondary slurrying of the grouting material. At this time, the first-level discharge valve 9 is closed, and the first-level silo 7 can be refilled with material and water for the first slurrying.

[0027] Finally, after the secondary pulping is completed, the pulped liquid is released through the secondary discharge valve 12.
