Description

Technical Field

[0001] The utility model relates to the technical field of mixed slurries, and specifically relates to a slurry feeding device. Background Art

[0002] Slurries are required in occasions such as building construction and floor construction. After the slurries solidify, they become the main body of the construction or serve as adhesives to connect components and the construction main body. The slurries are output after mixing various raw materials in a certain proportion and then stirring or grinding.

[0003] The existing common slurry mixing production process is as follows: Pour each raw material into a mixing hopper. After being stirred by the mixing hopper, it is sent out from the discharge port at the bottom, and then the slurry is filled into a drum for sealing on the production line through a pipeline. In this mixing production process, the common problem is that for slurries with higher viscosity or faster solidification speed, they will adhere to the mixing hopper or the filling pipeline. Since almost all mixing hoppers are vertical mixing hoppers, it will directly cause the discharge port to be blocked. The solution to this problem is to increase the power of the slurry pump pressure or the mixing power. However, this method will inevitably increase the energy consumption and cannot substantially solve the blockage problem, ultimately resulting in a reduction in the production efficiency of the mixed slurry.

[0004] In the prior art, there is also another method to balance and improve the production efficiency of mixed slurries, that is, to use multiple mixing hoppers and form multiple filling production lines respectively. In this way, the overall production rate of the mixed slurry is relatively increased. However, this method will greatly increase the cost of production equipment investment, and in fact, the production efficiency of each production line is still low.

[0005] A Chinese invention patent (Patent Application No.: 202111499946.3) discloses a slurry preparation system. The slurry preparation system includes a slurry production line, a sand and gravel production line, and a slurry mixing device. The slurry production line and the sand and powder production line respectively prepare slurry and sand powder. The slurry mixing device mixes the slurry and the sand powder to obtain slurry. The slurry and the sand powder are separately prepared and then mixed, which is beneficial to reducing the energy consumption of the slurry preparation system. It can be seen that the solution disclosed in this patent also produces various raw materials through different equipment and then mixes them. This mixing production process will inevitably increase the investment in the equipment conveying production line, and it is necessary to accurately grasp the viscosity and solidification rate of the slurry. In fact, the overall energy consumption is not reduced, the efficiency of a single production line is low, the conveying cost and conveying time of the slurry between equipment are too high, and it is restricted by the beat rate of each processing link and it is difficult to achieve high-efficiency production. Content of the Utility Model

[0006] In order to overcome the deficiencies of the prior art, the purpose of the utility model is to provide a slurry feeding device, which can smoothly and efficiently feed slurries with various viscosities and solidification speeds and avoid blockage.

[0023] The following describes the preferred embodiments of the utility model with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are only for the purpose of illustration and explanation of the utility model, and are not used to limit the utility model.

[0024] As Figure 1-2 shown, a slurry feeding device includes a stirring equipment 1, an emulsifying pump 2 and a filling output head 3. The stirring equipment 1 includes a cylinder body 101 and a slurry pushing mechanism arranged at the bottom of the cylinder body 101. The slurry pushing mechanism is arranged horizontally, and a slurry outlet is formed at the bottom of the cylinder body 101. The slurry outlet is connected to the inlet of the emulsifying pump 2 through a pipeline 4. There is more than one filling output head 3. The outlet of the emulsifying pump 2 is respectively connected to each filling output head 3 through a pipeline 4. Specifically, in Figure 1 , 2 , a part of the pipeline 4 connected to the filling output head 3 is shown at the outlet of the emulsifying pump 2. The outlet of the emulsifying pump 2 is also connected to the cylinder body 101 through a return pipe 5.

[0025] The slurry pushing mechanism arranged horizontally can reduce the funnel plugging effect of vertical discharging, avoid the slurry coagulation and blockage at the slurry outlet. At the same time, combined with the strong shearing force of the emulsifying pump 2, the slurry is further homogenized, crushed and emulsified. After passing through the emulsifying pump 2, the slurry will heat up, thus effectively preventing the solidification and viscosity effect caused by flowing and cooling, improving the slurry transportation rate. The slurry pumped out by the emulsifying pump 2 can quickly fill the slurry into the bucket through the filling output head 3. The process of feeding the slurry is smooth, and it can adapt to slurries with various viscosities and solidification speeds. Since the assembly line production is abandoned, the production cost is also greatly reduced, and at the same time, the slurry is efficiently fed and filled.

[0026] Among them, the stirring device 1 is a device that can mix and stir raw materials. As a preferred embodiment, a stirring mechanism 8 is provided in the cylinder body 101. The stirring mechanism 8 is horizontally arranged above the slurry pushing mechanism, so that the raw materials are fully stirred by the stirring mechanism 8 first, and then part of them fall due to their own weight and gather at the slurry pushing mechanism at the bottom of the cylinder body 101. The horizontally arranged stirring mechanism 8 makes the whole stirring device form a horizontal stirring cylinder, which is beneficial to discharging and can prevent blockage or slow discharging.

[0027] The emulsifying pump 2 in this embodiment adopts a three-stage emulsifying pump, specifically a pipeline three-stage emulsifying pump. It drives the rotor to rotate at a high speed through a motor, and makes the particle size of the slurry narrower by means of mechanical external force, achieving the effects of refining, homogenizing, dispersing and emulsifying, and at the same time increasing the temperature. After being processed by the emulsifying pump 2, the temperature of the slurry can be increased to 50°C - 85°C, thus forming a stable emulsion state, avoiding solidification blockage or viscosity reduction of the discharging speed, and being applicable to medium and high viscosity slurries.

[0028] Of course, for the case where slurry reaction stirring is required, a heating element and a temperature controller for assisting slurry reaction are provided in the cylinder body of this embodiment. The temperature controller is electrically connected to the heating element, and the heating element is controlled by the temperature controller. Its heating and temperature control make the stirring device form a reaction kettle.

[0029] As an embodiment of the stirring mechanism 8 with a specific structure, the stirring mechanism 8 includes a stirring shaft 81 and a double spiral belt 82 wound around the outer periphery of the stirring shaft 81. The stirring shaft 81 and the double spiral belt 82 are connected by a fixing frame 1383 to stir the slurry more fully.

[0030] The mixed slurry is then sent out to the emulsifying pump 2 through the slurry pushing mechanism at the bottom of the cylinder body 101. Due to the shearing force of the emulsifying pump 2, the slurry can be further homogenized and emulsified, and the temperature of the slurry can be increased. The horizontal slurry pushing mechanism can adopt a piston-type pushing mechanism or a pump pressure method to push the slurry. In a preferred embodiment, the slurry pushing mechanism is a screw propelling mechanism, which is arranged horizontally at the bottom of the cylinder body 101. With such a configuration, the slurry at the bottom of the cylinder body 101 will not sink to the bottom and cause blockage. In addition, the filling output head 3 can adopt devices such as a valve body or a nozzle, and its quantity is configured according to needs. With more filling output heads 3, when the pressure of the slurry pushing mechanism and the emulsifying pump 2 is sufficient, a parallel multi-channel slurry feeding and filling output can be formed, which is more conducive to improving production efficiency.

[0031] To further make full use of the filling time and improve production efficiency, a first pneumatic valve 6 for pressure holding is provided on the return pipe 5 in this embodiment. In this way, when the filling of the bucket is completed, during the time gap between the full bucket being sent out and the empty bucket being sent in, the first pneumatic valve 6 can be controlled to close. Since the filling output head 3 is in the closed state, a pressure holding of the slurry will be formed in the pipeline 4 output by the slurry pushing mechanism and in the pipeline 4 where the emulsifying pump 2 sends the slurry to the filling output head 3. The slurry is squeezed by the conveying pressure in the pipeline 4 and stored temporarily. When the empty bucket arrives and is ready for filling, when the filling output head 3 works again to output the slurry, the conveying pressure in the pipeline 4 is released, and the slurry is sent out at high speed, realizing efficient conveying and energy saving. At this time, the first pneumatic valve 6 can be controlled to open, and part of the slurry will flow back to the cylinder body 101 through the return pipe 5 to coordinate the control of the amount of filling slurry.

[0032] In another embodiment, a second pneumatic valve 7 for controlling the filling feed is provided on the pipeline 4 between the slurry outlet and the inlet of the emulsifying pump 2. The opening and closing of the second pneumatic valve 7 can overall control the opening and closing of all the filling output heads 3. In addition, when the pipeline 4 can be arranged and configured, the slurry in different pipelines 4 can also be selected to enter the filling output head 3, so the flexibility is higher.

[0033] When configuring the slurry pushing mechanism, to further reduce the blockage at the bottom of the cylinder, a pushing groove 102 for accommodating the slurry pushing mechanism is provided at the bottom of the cylinder body 101. The pushing groove 102 protrudes downward from the bottom of the cylinder body 101, so that the slurry will fall into the pushing groove 102 more fully. The notch of the pushing groove 102 straddles the bottom of the cylinder body 101 and is communicated with the inside of the cylinder body 101, which is also conducive to the slurry at various parts of the cylinder body 101 entering the pushing groove 102 more evenly. One end of the pushing groove 102 is closed, and the other end of the pushing groove 102 is used as the slurry outlet. This configuration of the pushing groove 102 can better adapt to the slurry pushing mechanism and is also more conducive to forming a piston-type slurry feeding, extremely effectively reducing the slurry blockage, and is more suitable for the situation of producing slurries with higher viscosities.

[0034] The slurry feeding device of this embodiment further comprises a filling bracket 9, and each filling output head 3 is fixedly mounted on the filling bracket 9. Figure 1 、 2 The general schematic diagram of the filling bracket 9 is shown in the figure, which can be installed on the body of the device. The filling bracket 9 is connected to a moving mechanism 10 in a transmission manner. A plurality of filling output heads 3 are integrated and installed through the filling bracket 9, and can be driven to move by the moving mechanism 10 at the same time, so that the filling output head 3 can better avoid the barrel entry action and align with the filling inlet of the barrel, which is conducive to a more consistent filling action. Specifically, the moving mechanism 10 is a cylinder 11, and the cylinder 11 is installed on a sliding plate 12. The sliding plate 12 is slidably connected to a fixed frame 1383. The sliding plate 12 is fixedly connected to the filling bracket 9. The piston rod of the cylinder 11 is connected to the fixed frame 1383, and the cylinder body 101 of the cylinder 11 is fixed to the sliding plate 12. When the piston rod of the cylinder 11 is extended, it pushes to the fixed frame 1383, reacts on itself and drives the sliding plate 12 to extend out of the fixed frame 1383. The movement of the sliding plate 12 will drive the filling bracket 9 to drive the filling output head 3 to move as a whole.

[0035] To better control the amount of slurry filled into the barrel and achieve automatic filling control, a flow control valve 14 is provided on the filling output head 3 for detecting the slurry filling flow rate. The flow control valve 14 can control the flow rate output by the filling output head 3 to facilitate controlling the amount of slurry filled into the barrel. Of course, the filling time can be controlled or a flow sensor can be added to achieve intelligent control of the slurry filling.

[0036] The implementation methods of the present invention are not limited to these. According to the above-mentioned embodiments of the present invention, by utilizing conventional technical knowledge and customary means in this field, without departing from the above-mentioned basic technical ideas of the present invention and without conflict, the above-mentioned preferred embodiments can also be modified, replaced or combined in various other forms. The other embodiments obtained all fall within the scope of protection of the present invention.
