Description

Technical Field

[0001] The present application relates to the technical field of mixing equipment, and in particular to a solid waste gelling material mixing equipment. Background Art

[0002] With growing awareness of environmental protection and resource recycling, the research and application of solid waste cementitious materials has become a hot topic in the building materials industry. By transforming various types of solid waste through specialized processes into new materials with cementitious properties, solid waste cementitious materials not only effectively address solid waste disposal issues but also provide a new source of raw materials for the building materials industry.

[0003] Mixing is crucial in the preparation of solid waste cementitious materials. Uneven mixing can easily lead to uneven distribution of the material's internal components, which in turn affects its overall performance, such as strength and durability. Existing mixing equipment is mainly divided into mechanical, pneumatic, and pneumatic mixing types. Pneumatic mixing mixers use a fan to inflate the mixing chamber, utilizing a compressed air source to generate pulsed airflow to agitate the material. This airflow lifts, moves, and flips the powdered material within the chamber, and then agitates it with the agitator shaft, rapidly mixing the material.

[0004] However, most existing mixing equipment sets the air source device at the bottom of the mixing bin. Once the mixing equipment stops due to an emergency, the high pressure in the mixing bin can easily pump the powder material into the air source device, causing the air source device to be blocked or worn, affecting the production efficiency and cost of solid waste cementitious materials. Utility Model Content

[0005] The purpose of the utility model is to provide a solid waste gelling material mixing device, which can effectively solve the problem of gas source device blockage during the mixing process, thereby improving the production efficiency of solid waste gelling materials and reducing production costs.

[0006] This application is achieved through the following technical solutions, specifically:

[0007] A solid waste cementitious material mixing equipment, comprising: a mixing bin, a feed port arranged at the top of the mixing bin, a mixing mechanism installed inside the mixing bin, an overflow mechanism arranged on one side of the mixing bin, an air source device installed below the mixing mechanism, and a discharge port arranged between the mixing bin and the overflow mechanism; the air source device comprises a first air inlet channel arranged at the bottom of the mixing bin, a plurality of air outlet nozzles arranged at the upper part of the first air inlet channel, a second air inlet channel horizontally arranged along the upper part of the outer side of the mixing bin, and a fan connected to the second air inlet channel; the air outlet nozzle is connected to the mixing bin, and the second air inlet channel extends downward from the upper part of the mixing bin to form a plurality of branch pipes, and the branch pipes pass through the bottom of the mixing bin and are connected to the first air inlet channel.

[0008] In this solution, a first air inlet channel located at the bottom of the mixing chamber and multiple air outlet nozzles located at the top create a bottom-up airflow, helping to lift and stir the materials during mixing, further promoting uniform mixing. Furthermore, this solution places a second air inlet channel at the upper outer portion of the mixing chamber. Even if there are pressure fluctuations within the mixing chamber, the higher and horizontally positioned second air inlet channel minimizes pressure fluctuations within the chamber, reducing the risk of material being pushed into the fan by pressure differences. This helps improve mixing efficiency, ensures equipment stability, and extends equipment life.

[0009] As an improvement to the branch pipe in the present application, the branch pipe is composed of a first vertical section, a curved section and a second vertical section. The curved section includes at least two identical bend units, and the bend units are interconnected to form an S-shaped pipe.

[0010] In this solution, by setting an S-shaped pipe on the branch pipe, the impact of air pressure changes in the mixing chamber caused by equipment shutdown on the fan can be reduced, thereby preventing powdered materials from being pumped into the fan due to air pressure fluctuations, further improving the stability and reliability of the equipment and reducing the maintenance cost of the equipment.

[0011] As an improvement to the air outlet nozzle in the solution of the present application, the top of the air outlet nozzle is closed, and the side of the air outlet nozzle is provided with an air outlet hole.

[0012] In this solution, sealing the top of the nozzle prevents material from falling directly into it, reducing the risk of nozzle blockage. Placing the outlet holes on the side of the nozzle not only prevents the nozzle from being blocked by material accumulation, but also optimizes airflow distribution, reducing the risk of powdered material being carried into the fan by the airflow.

[0013] As another improvement to the air outlet nozzle in the solution of the present application, an air intake control valve is provided at the bottom of the air outlet nozzle.

[0014] As another improvement to the air source device in the present application, the air source device is symmetrically arranged along both sides of the mixing bin.

[0015] Furthermore, the stirring mechanism includes: at least one stirring shaft connected to both ends of the stirring chamber and a motor connected to one end of the stirring shaft.

[0016] Furthermore, the overflow mechanism includes: an overflow plate arranged on the inner side of the discharge port, a movable plate installed above the overflow plate, and an electric push rod fixedly connected to the movable plate.

[0017] The beneficial effects of this application are:

[0018] 1. This application solution, through the first air inlet channel set at the bottom of the mixing chamber and the multiple air outlet nozzles at the top, can form an airflow from bottom to top, which helps to lift and turn the materials during the mixing process, further promoting the uniform mixing of the materials. In addition, this solution sets the second air inlet channel at the upper outer part of the mixing chamber. Even if there is a change in air pressure in the mixing chamber, the air pressure change inside the mixing chamber is relatively small due to the high position and horizontal setting of the second air inlet channel, thereby reducing the risk of the material being pushed into the fan by the air pressure difference, helping to improve mixing efficiency, ensure equipment stability and extend equipment life.

[0019] 2. This application solution can reduce the impact of air pressure changes in the mixing chamber caused by equipment shutdown on the fan by setting an S-shaped pipe on the branch pipe, thereby preventing powdered materials from being pumped into the fan due to air pressure fluctuations, further improving the stability and reliability of the equipment, and reducing the maintenance cost of the equipment.

[0020] 3. This application solution can prevent materials from falling directly into the air outlet nozzle by sealing the top of the air outlet nozzle, thereby reducing the risk of materials blocking the nozzle. Setting the air outlet hole on the side of the air outlet nozzle can not only prevent the air outlet nozzle from being blocked by material accumulation, but also optimize the distribution of air flow, reducing the risk of powdered materials being carried into the fan by the air flow.

[0021] In addition to the technical problems solved by the present invention, the technical features that constitute the technical solutions, and the advantages brought about by the technical features of these technical solutions described above, other technical problems that can be solved by the present invention, other technical features included in the technical solutions, and the advantages brought about by these technical features will be further described in detail in conjunction with the accompanying drawings.

[0029] The following will be combined with the Figures 1 to 5 The embodiments of the technical solution of the present application are described in detail. The following embodiments are only used to more clearly illustrate the technical solution of the present application and are therefore only examples and are not intended to limit the scope of protection of the present application. In addition, the technical features involved in the various embodiments of the present invention described below may be combined with each other as long as they do not conflict with each other.

[0030] Figure 1 The figure shows a structural diagram of a solid waste cementitious material mixing device. Figure 3 The schematic cross-sectional view of a part of the structure of a solid waste cementitious material mixing device is shown. Figure 1 and 3 As shown, the embodiment of the present application provides a solid waste cementitious material mixing device, comprising: a mixing chamber 1, a feed port 11 provided at the top of the mixing chamber 1, a mixing mechanism 2 installed inside the mixing chamber 1, an overflow mechanism 3 provided on one side of the mixing chamber 1, an air source device 4 installed below the mixing mechanism 2, and a discharge port 5 provided between the mixing chamber 1 and the overflow mechanism 3;

[0031] The air source device 4 includes a first air inlet channel 41 arranged at the bottom of the mixing chamber 1, a plurality of air outlet nozzles 42 arranged on the upper part of the first air inlet channel 41, a second air inlet channel 43 horizontally arranged along the upper outer part of the mixing chamber 1 and a fan 44 connected to the second air inlet channel 43; the air outlet nozzle 42 is connected to the mixing chamber 1, and the second air inlet channel 43 extends downward from the upper part of the mixing chamber 1 to form a plurality of branch pipes 45, and the branch pipes 45 pass through the bottom of the mixing chamber 1 and are connected to the first air inlet channel 41.

[0032] Specifically, the air source device 4 operates as follows: after the fan 44 is activated, air is drawn into the second air inlet channel 43. From the second air inlet channel 43, the air is transported downward through multiple branch pipes 45 to the first air inlet channel 41. The air in the first air inlet channel 41 is then ejected into the interior of the mixing chamber 1, which is connected to the mixing chamber 1, through multiple air outlet nozzles 42 evenly distributed at the bottom of the mixing chamber 1. The coordinated use of the stirring mechanism 2 and the air source device 4 enables efficient mixing of solid waste cementitious materials.

[0033] It should be understood that due to the action of the fan 44, during the mixing process, the air pressure inside the mixing chamber 1 is greater than the air pressure outside the equipment. When the mixing equipment unexpectedly stops, due to the difference in air pressure inside and outside the equipment, the powdered material inside the mixing chamber 1 may be accidentally pumped into the air outlet nozzle 42 and the air inlet channel, or even enter the fan 44, causing damage to the fan or more serious safety accidents. Therefore, in order to solve this problem, the second air inlet channel 43 is set at the upper part of the outer side of the mixing chamber 1. In this way, even if there is an air pressure change in the mixing chamber 1, since the second air inlet channel 43 is located higher and is set horizontally, the air pressure change inside it is relatively small, thereby reducing the risk of material being pushed into the fan 44 by the air pressure difference.

[0034] In one implementation, the stirring mechanism 2 includes: at least one stirring shaft 21 connected to both ends of the stirring chamber 1 and a motor 22 connected to one end of the stirring shaft 21. Preferably, the stirring shaft 21 is a stirring shaft 21 with opposite stirring directions.

[0035] In one implementation, the overflow mechanism 3 includes: an overflow plate 31 arranged inside the discharge port 5 , a movable plate 32 installed above the overflow plate 31 , and an electric push rod 33 fixedly connected to the movable plate 32 .

[0036] Specifically, the overflow plate 31 is used to guide the mixed materials to pass through. After the materials are mixed, they are pushed to the overflow plate 31 by the blades of the stirring shaft 21 in the stirring mechanism 2. If the amount of materials is insufficient, the stirring shaft 21 continues to stir until the materials are piled up to a sufficient height to pass over the overflow plate 31 and are discharged from the discharge port 5. Figure 3 A movable plate 32 is positioned above the overflow plate 31 and is driven by a motorized push rod 33 located outside the mixing chamber 1. Its movable end is fixed to the movable plate 32, while its fixed end is connected to the outer shell of the mixing chamber 1. The motorized push rod 33 controls the horizontal movement of the movable plate 32 to adjust the gap above the overflow plate 31 to connect with the discharge port 5 for discharging. If the material is not mixed enough, the movable plate 32 prevents overflow, thereby extending the mixing time.

[0037] Figure 2 The schematic diagram of another solid waste cementitious material mixing equipment is shown, which aims to solve the problems existing in the prior art, such as Figure 2 As shown, in one implementation, the branch pipe 45 is composed of a first vertical section 451, a curved section 452 and a second vertical section 453, and the curved section 452 includes at least two identical curved pipe units, which are interconnected to form an S-shaped pipe.

[0038] Specifically, the branch pipe 45 is a key component connecting the fan 44 and the inside of the mixing bin 1, and its design is directly related to the smoothness and operating efficiency of the airflow in the mixing equipment. This embodiment can effectively absorb and disperse air pressure fluctuations by introducing an S-shaped pipe structure in the branch pipe 45. When the air pressure inside the mixing bin 1 changes, the airflow in the S-shaped pipe will be diverted and buffered multiple times, thereby reducing the direct impact of the air pressure fluctuation on the fan 44. The S-shaped pipe can also intercept part of the material pumped into the branch pipe 45. Even if the equipment is in a shutdown or adjustment state, it can ensure that the fan 44 maintains a relatively stable operating environment, avoiding the risk of powdered materials being pumped in due to air pressure fluctuations.

[0039] Figure 4 The figure shows a schematic structural diagram of the first air inlet channel in a solid waste cementitious material mixing device of the present application. Figure 5 Schematic diagram of the cross-sectional structure of the first air inlet channel is shown. Figures 4-5 As shown, in one implementation, the top of the air outlet nozzle 42 is closed, and the side of the air outlet nozzle 42 is provided with an air outlet hole 421.

[0040] Specifically, the air outlet holes 421 are provided on the side of the air outlet nozzle 42. Preferably, at least two air outlet holes 421 are symmetrically provided on the side of the air outlet nozzle 42. The provision of the air outlet holes 421 allows the air outlet nozzle 42 to blow air in all directions during mixing. On the one hand, the air in the first air inlet channel 41 can be evenly distributed and sprayed into the mixing chamber 1. On the other hand, it can prevent the material from being deposited at the bottom of the mixing chamber 1.

[0041] Continue to read Figure 5 In order to adjust the amount of gas entering the gas outlet nozzle 42, in one implementation, an air intake control valve 422 is provided at the bottom of the gas outlet nozzle 42. Specifically, during the mixing process, the operator can adjust the opening of the air intake control valve 422 according to the properties of the materials, the requirements of the mixing process, and the actual situation in the mixing chamber 1 to change the flow rate and flow rate of the gas entering the mixing chamber 1 to achieve the best mixing effect.

[0042] On the basis of the above embodiments, continue to refer to Figure 1 In one implementation, the air source device 4 is symmetrically arranged along both sides of the mixing chamber 1.

[0043] Specifically, the air source device 4 is symmetrically arranged along both sides of the mixing bin 1, and the second air inlet channels 43 on both sides can be connected to a fan 44. Inside the mixing bin 1, two groups of first air inlet channels 41 are symmetrically arranged below the stirring mechanism 2. Preferably, the air outlet holes 421 of the air outlet nozzles 42 on the two groups of first air inlet channels 41 are arranged relative to each other. This design can ensure the uniform distribution of gas in the mixing bin 1. When the air source devices 4 on both sides work at the same time, they will inject gas into the interior from both sides of the mixing bin 1 at the same time, forming a symmetrical airflow. This airflow can more effectively penetrate and stir the material layer, so that the material and gas can be more fully contacted and mixed, thereby improving the mixing efficiency.
