Description

Technical Field

[0001] This utility model belongs to the field of mud treatment, specifically an automatic mixing device for mud and chemicals in mud treatment processes. Background Technology

[0002] Slurry treatment is a process that uses physical, chemical, and mechanical methods to separate solids and liquids in engineering slurry. Its core objective is to improve the efficiency of pile foundation construction and reduce environmental impact. Due to the characteristics of slurry, large-scale slurry treatment cannot be achieved through natural sedimentation. In actual construction, chemicals are typically added to the slurry to initiate a chemical reaction and achieve the desired effect.

[0003] In the existing mud treatment process, the agent is added by mixing the agent in a special mixing device and then pumping it to the mud tank for further mixing and action. The method of adding mud by pumping has many drawbacks: (1) Pumping requires the investment of equipment such as pumps, pipelines, valves, containers, and pressure gauges, which is relatively complex. Controlling the amount of agent used requires a control system or a device that matches the pump. The initial investment in purchasing a complete set of pumping equipment is large. Moreover, pumping relies on power drive (such as motors and hydraulic systems). Continuous operation will consume a lot of electricity or fuel. For scenarios with large flow and long distance transportation, the energy consumption cost is particularly significant and may increase the overall operating cost of the treatment process.

[0004] (2) Difficult to maintain: Mud treatment agents often contain corrosive and abrasive components (such as acids, alkalis, solid particles, etc.). Long-term pumping will cause wear or corrosion of internal parts of the pump body (such as impellers, seals, and inner walls of pipes), requiring regular replacement of parts and high maintenance frequency; moreover, the complex pipeline system may be blocked by problems such as agent precipitation and crystallization, and the cleaning process is cumbersome, time-consuming and labor-intensive.

[0005] (3) If the viscosity of the agent is extremely high (such as polymer flocculant solution), the pump efficiency may decrease due to excessive resistance during pumping, or even "pumping difficulty" may occur. It is necessary to add an additional stirring device or dilute the agent, which will affect the stability of the process. If some agents are subjected to shear force during pumping (such as high-speed rotation of centrifugal pump impeller), it may cause the molecular structure of the agent to be destroyed, reducing its performance (such as weakening the flocculation effect of flocculant).

[0006] (4) The pump body will generate a lot of noise when it is running (especially centrifugal pumps, plunger pumps, etc.). If the processing workshop does not take sound insulation measures, it may affect the surrounding working environment. Long-term exposure to noise may also damage the hearing of operators.

[0007] (5) If the pumping system malfunctions (such as pump shaft breakage, motor burnout, pipeline rupture, etc.), it may lead to interruption of reagent dosing, or even require suspension of the entire treatment process for maintenance, affecting the continuity of mud treatment.

[0032] The embodiment provides an automatic mixing device for mud and chemicals, such as Figures 1 to 6 As shown, the mixing device includes a mud trough 1 and a reagent addition tank 2. The mud trough 1 is an elongated groove with open ends, and it is arranged at an angle, with its inlet higher than its outlet. From the inlet to the outlet, the mud trough 1 is sequentially provided with a reagent addition area 100, a reagent mixing area 101, and a discharge area 102. A variable diameter section 103 is provided between the outlet end of the reagent mixing area and the inlet end of the discharge area of ​​the mud trough 1, and the width of the variable diameter section 103 is smaller than that of the reagent mixing area 101 and the discharge area 102. The mud trough of this invention is designed with an irregular shape, and the variable diameter section 103 in the downstream direction better adjusts the flow rate of the mud and increases the degree of reagent mixing. The reagent addition box 2 is mounted above the reagent delivery area 100 of the mud flow channel 1. A reagent delivery port 200 is located at the bottom of the reagent addition box 2, and a reagent addition adjustment plate 3 is located at the reagent delivery port 200. The reagent mixing area of ​​the mud flow channel 1 is equipped with a mixing baffle 4, a slurry mixing rod 5, and slurry surging vanes 6. A row of slurry surging vanes 6 is arranged along the width of the mud flow channel 1. Each slurry surging vane 6 is V-shaped, with the V-shaped opening of each vane 6 facing the discharge direction. The slurry mixing rods 5 are arranged in multiple parallel directions along the width of the slurry flow channel 1, with their diameters increasing sequentially from the inlet to the outlet. The mixing baffles 4 are also arranged in the width direction of the slurry flow channel 1, and multiple slurry inlets 7 are provided on the upper, lower, or both sides of the mixing baffles 4. At least two mixing baffles 4 are provided, arranged in parallel, with the slurry inlets 7 on adjacent mixing baffles 4 located at different positions. In this embodiment, the slurry surging flange 6, the slurry mixing rods 5, and the mixing baffles 4 are arranged in parallel sequentially from the inlet to the outlet. Two mixing baffles 4 are provided; one mixing baffle 4 has multiple slurry inlets 7 on its upper part, while the other mixing baffle 4 has slurry inlets 7 distributed on both its upper and lower parts, with the upper slurry inlets 7 staggered from those on the first mixing baffle 4.

[0033] The mud flow channel 1 of this utility model is equipped with a mixing baffle 4, a slurry mixing rod 5, and a slurry surging wing plate 6. By changing the slurry flow path through these three mechanical devices, the free mixing of the slurry can be achieved, which can greatly reduce equipment investment and energy consumption. The slurry surging wing plate 6 is located at one end near the reagent delivery area 100 to adjust the horizontal movement trajectory of the slurry flow. The slurry mixing rod 5 is distributed in the middle area of ​​the reagent mixing area 101, and the vertical movement trajectory of the slurry flow can be adjusted by adjusting its height and diameter. The mixing baffle 4 is located at one end away from the reagent delivery area 100, and the staggered mud inlets 7 further mix the slurry and reagent.

[0034] In the embodiments, such as Figures 1 to 6 As shown, a chemical storage tank 8 is also provided above the chemical delivery area 100 of the mud flow channel 1. The chemical storage tank 8 is mounted on the opening of the mud flow channel 1. Both the chemical storage tank 8 and the chemical addition tank 2 are open-top boxes, and a hoisting mechanism 9 is provided between the chemical storage tank 8 and the chemical addition tank 2. The agent addition tank 2 is installed at one end of the agent delivery area 100 of the mud flow channel 1, near the slurry inlet. The agent storage tank 8 is installed at one end of the agent delivery area 100 of the mud flow channel 1, near the agent mixing area 101. The hoisting mechanism 9 includes a support rod and a hoisting slide. One end of the hoisting slide is located above the opening of the agent storage tank 8, and the other end is located above the opening of the agent addition tank 2. A hoisting assembly is installed on the hoisting slide. The hoisting assembly can be a conventional hoisting assembly with its own walking mechanism that can move along the hoisting slide to hoist the agent packs in the agent storage tank 8 to the top of the agent addition tank 2. The agent packs can be manually cut open and the agent can be added into the agent addition tank 2, or they can be cut open and added using existing mechanical methods. The hoisting mechanism 9 is equipped with a matching lifting device and corresponding safety devices.

[0035] In this embodiment, the medicine dispensing port 200 at the bottom of the medicine dispensing box 2 is an elongated opening with a grid at the opening. The medicine dispensing adjustment plate 3 is a plug-in pull plate structure, including a pull plate 300. Push-pull grooves 301 are symmetrically provided on both sides of the medicine dispensing port 200 along its length. The two sides of the pull plate 300 are inserted into the push-pull grooves 301 respectively, and slide along the push-pull grooves 301 to adjust the opening size of the medicine dispensing port 200 during the pulling process. After the pull-out plate 300 is moved, the agent can fall from the agent inlet 200. The opening can be adjusted to verify the number of grids at the agent inlet 200 position, thereby determining the agent dosage. For example, 50 parts of slurry require 1 part of agent. Calculate the volume of slurry flowing through the tank per unit time, adjust the opening size, and calculate the volume of agent falling per unit time. The slurry outlet area 102 of the mud flow channel 1 is equipped with a slurry detector 10 near the slurry outlet, and a slurry detector is installed at the end of the mud tank to monitor the slurry composition and verify relevant indicators of subsequent mud treatment.

[0036] In use, this invention involves installing a mud flow channel 1 on a mud conveying channel. During the natural flow of the mud, chemicals are added into the mud flow channel 1. After entering the mud flow channel 1, the chemicals facilitate the natural flow of the mud forward. During this flow, the flow path of the mud is altered by three mechanical devices: a mixing baffle 4 in the mud mixing zone, a slurry mixing rod 5, and a slurry surging wing plate 6. This achieves free mixing of the slurry, significantly reducing equipment investment and energy consumption. Combined with the downstream diameter-changing zone 103, the flow rate of the mud is better adjusted, increasing the degree of chemical mixing. The mud flow channel 1 in this invention can be set horizontally or inclined; a slight inclination is acceptable to ensure mud fluidity.

[0037] The above description is merely one embodiment of this utility model, and while it is quite specific and detailed, it should not be construed as limiting the scope of this utility model. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the appended claims.
