Description

Technical Field

[0001] The utility model relates to the technical field of skid-mounted material mixing, in particular to a skid-mounted material mixing system. Background Art

[0002] The skid-mounted mixing system is an integrated, mobile equipment combination that is widely used in the material mixing and preparation process in the fields of petrochemicals, fine chemicals, and pharmaceutical chemicals. In the field of oil development, the skid-mounted acid continuous mixing device is used in the process technology of improving the permeability of oil layers or removing oil layer blockages; the large-scale fracturing fluid continuous mixing device is used in the fracturing construction of oil and gas fields, and can quickly prepare a large amount of fracturing fluid on site to achieve "mix and use" and "prepare and use"; in the fine chemical and pharmaceutical manufacturing process, the skid-mounted mixing system can be used for small-batch, multi-variety, high-quality chemical product production; in modern chemical production, the skid-mounted mixing system is valued for its high efficiency, flexibility and mobility.

[0003] At present, if the existing skid-mounted mixing system only relies on a single material level monitoring point during use, the system will not trigger a response until the material is consumed to the monitoring point, causing the production line to suddenly stop due to material depletion, resulting in production interruption. In addition, when the feeding system is started, it may cause overfilling of material due to the lack of accurate judgment of the actual material amount in the silo. The single material level monitoring point cannot provide sufficient warning time, making it impossible for the operator or the automation system to take remedial measures in time, which not only affects production continuity, but also increases additional cleaning and restart costs. Therefore, the present application provides a skid-mounted mixing system to meet the needs. Utility Model Content

DETAILED DESCRIPTION

[0026] The following is a detailed description of a polymer material injection molding device provided by the utility model in combination with the accompanying drawings and specific embodiments. At the same time, it is explained here that in order to make the embodiments more detailed, the following embodiments are the best and preferred embodiments, and those skilled in the art may also adopt other alternative methods to implement some known technologies; and the accompanying drawings are only for more specific description of the embodiments, and are not intended to specifically limit the utility model.

[0027] like Figure 1 , Figure 2 and Figure 4 As shown, an embodiment of the utility model provides a skid-mounted mixing system, comprising: a box body 1; a silo 10, arranged in the box body 1; a grading part 13, arranged on the silo 10, the grading part 13 comprising: a high-level sensor 131, arranged on the top of the silo 10, for preventing excessive filling of materials; a low-level sensor 133, arranged at the bottom of the silo 10, for triggering emergency refilling of the system; a middle-level sensor 132, arranged on the silo 10, for issuing an alarm when the material level drops to a certain level; and located between the high-level sensor 131 and the low-level sensor 133.

[0028] By setting a high-level material level sensor 131, the high-level material level sensor 131 monitors the highest level of the material inside the silo 10. Once the material reaches a preset high level, the sensor will trigger a signal to prevent the silo 10 from being overfilled, avoiding material overflow or system overload operation; by setting a low-level material level sensor 133, the low-level material level sensor 133 monitors the lowest level of the material inside the silo 10. When the material drops to a preset low level, the sensor will sound an alarm to ensure that there is enough material in the silo 10 for the system to use, avoiding production interruptions due to material shortages, and starting an emergency refilling procedure when the material level is too low to ensure production continuity; by setting a middle-level material level sensor 132, the middle-level material level sensor 132 detects the state of the material in the silo 10 at an intermediate level. As a supplement between the high-level material level sensor 131 and the low-level material level sensor 133, it provides more detailed material level information, which helps to better control material inventory. When the material level drops to the middle level, it can issue an early warning to remind the operator to pay attention to the material status and adjust the material replenishment strategy in time.

[0029] like Figure 1 , Figure 2 and Figure 3 As shown, it also includes: a first material tank 5, which is arranged on the box body 1; a storage box 3, which is arranged on the box body 1 and is located on the front side of the first material tank 5; a feeding screw conveyor 6, one end of which is connected to the bottom of the first material tank 5 and the other end is connected to the storage box 3.

[0030] By setting up a feeding screw conveyor 6, the main function is to transport materials from the first material tank 5 to the storage box 3, and can transport bulk materials from one position to another. It is particularly suitable for horizontal or inclined material transportation, ensuring that the material is stably and continuously transported from the first material tank 5 to the storage box 3, providing sufficient raw material supply for the subsequent mixing process, and realizing the automation and continuous transportation of materials, thereby improving material processing efficiency and reducing labor costs.

[0031] like Figure 2 , Figure 3 and Figure 5 As shown, it also includes: a second material tank 12, which is arranged on the box body 1 and is located on one side of the storage box 3; a first conveying pipe 8, one end of which is connected to the second material tank 12; a weighing screw conveyor 7, which is arranged on the storage box 3 and is connected to the first conveying pipe 8; a vertical screw conveyor 4, one end of which is arranged on the top of the storage box 3, and the other end is connected to the weighing screw conveyor 7.

[0032] By setting up a weighing screw conveyor 7, not only can the material be conveyed, but the material can also be accurately weighed during the conveying process. Usually, it includes a spiral blade shaft and a weighing sensor. The material moves forward under the push of the spiral blade, and the weighing sensor records the weight of the material. In the mixing system, the purpose of the weighing screw conveyor 7 is to ensure that the material can be added to the mixing process in an accurate weight or volume ratio. This is particularly important for industrial production that requires strict control of the formula ratio. For example, in the chemical, pharmaceutical, food and other industries, by using the weighing screw conveyor 7, the accuracy and consistency of the mixing can be greatly improved, and product quality problems caused by improper material ratios can be reduced.

[0034] The water pump 17 is provided to be mainly responsible for conveying liquid, and is connected to external equipment to pump the liquid to a designated position in the mixing process when the system is in use; the mixing pump 16 is provided to promote the flow of materials in the mixing process to ensure that all components are fully mixed.

[0035] like Figure 2 and Figure 5 As shown, it also includes: a main flow meter 18, which is arranged on the first delivery pipe 8; a sub-flow meter 19, which is arranged on the first delivery pipe 8; a sub-valve 20, which is arranged on the first delivery pipe 8; and the sub-valve 20, the sub-flow meter 19 and the main flow meter 18 are distributed in sequence from left to right; a second delivery pipe 14, one end of which is connected to the bottom of the second material tank 12, and the other end is connected to the mixing pump 16.

[0036] By setting up the main flow meter 18, its main function is to measure and monitor the total flow of materials through the first conveying pipe 8. It can provide continuous and real-time flow data to ensure that the mixing system can accurately grasp the material delivery volume; the function of the branch flow meter 19 is to monitor the flow of specific branches or components through the first conveying pipe 8, and is usually used in conjunction with the branch valve 20 to achieve independent control of the flow of different materials or components.

[0037] like Figure 2 and Figure 5 As shown, it also includes: a shunt pipe 15, one end of which is connected to the second delivery pipe 14, and the other end is connected to the first delivery pipe 8; and the other end of the shunt pipe 15 is located between the main flow meter 18 and the sub-flow meter 19. By setting the shunt pipe 15, a main valve is set on the shunt pipe 15 to control the opening or closing of the shunt pipe 15; the second delivery pipe 14 is also provided with a control valve to control the opening or closing of the second delivery pipe 14.

[0038] like Figure 2 , Figure 3 and Figure 5 As shown, it also includes: a feed pipe 9, one end of which is connected to the mixing pump 16, and the other end is connected to the silo 10; a discharge part 2, which is arranged on the box body 1, and the discharge part 2 includes: a flow pipe 21, one end of which is connected to the bottom of the silo 10, and the other end is U-shaped; two discharge pumps 22, which are arranged on the box body 1, and the other ends of the flow pipe 21 are respectively connected to the two discharge pumps 22; two discharge pipes 23, which are respectively connected to the two discharge pumps 22, and the two discharge pipes 23 are both provided with a discharge flow meter.

[0039] like Figure 2 As shown, it also includes: a control cabinet 11, which is arranged on the box body 1. The control cabinet 11 is the central nervous system of the mixing system, which includes various control circuits, computer systems and human-machine interfaces, and is used to monitor and control the operation of the entire mixing system, and is connected to all devices in the system for control.

[0040] The technical solution provided by the utility model uses the control cabinet 11 to start the system operation. The material is first sent from the first material tank 5 to the storage box 3 through the feeding screw conveyor 6, and then the material in the storage box 3 is transported to the weighing screw conveyor 7 for weighing through the vertical screw conveyor 4. The fully weighed material is sent to the second material tank 12 through the first conveying pipe 8. When water needs to be transported, it is divided into two situations through the external water pump 17. Situation 1: The water flows into the first conveying pipe 8, passes through the main flow meter 18 and the diverter pipe 15, and enters the second conveying pipe 14. The material in the second material tank 12 also enters the mixing pump 16 through the second conveying pipe 14; Situation 2: The water flows into the first conveying pipe 8, and enters the second conveying pipe 14 through the main flow meter 18 and the diverter pipe 15 ...
