[0001] This utility model relates to a liquid feeding device, and more particularly to a digitally intelligent modular mobile feeding device, which is applicable to fields such as chemical industry, pharmaceutical industry, and environmental protection. Background Technology

[0002] The pharmaceutical and chemical industry involves many liquid drummed materials. To feed these materials into the reactor, the following steps are required: first, the liquid material in the drum is transferred to a fixed container for metering by a pump, and then the metered liquid material is added to the reactor.

[0003] The mobile feeding devices disclosed in the technology basically follow the original feeding method. For example, patent publication number CN206838028U describes a mobile slurry liquid feeding device, which includes a movable storage tank, a liquid inlet pipe and a solid inlet pipe at the upper end of the tank, a stirring device inside the tank, and a feeding pipe at the lower end of the tank. A first valve is installed on the liquid inlet pipe, a second valve on the solid inlet pipe, and a third valve on the feeding pipe. This design simply adds a stirring device.

[0004] Existing mobile feeding methods all suffer from low metering accuracy or require a dedicated metering platform, are complex in operation, have cumbersome feeding procedures, require multiple material transfers, are inefficient to meet the requirements of modern production, and also pose a risk of leakage. Summary of the Invention

[0005] The purpose of this invention is to solve the above-mentioned problems and provide a digitally intelligent modular mobile feeding device. Through modular assembly and system integration, it organically combines raw material barrels or mobile containers with metering and discharging systems on a mobile vehicle, enabling materials to be directly fed into the reactor. It features reduced transfer containers and operation steps in the workshop, saving investment, reducing leakage risks, and precise feeding.

[0006] The above-mentioned technical problems of this utility model are mainly solved by the following technical solution: a digital modular assembly mobile feeding device, including a mobile vehicle, characterized in that a digital operation area, a storage bin and a discharge system area are provided on the mobile vehicle by modular assembly; the modular assembly includes a chute located on the chassis of the mobile vehicle, and the bottom of the digital operation area, the storage bin and the discharge system area are all provided with slide rails that cooperate with the chute, and the chute is provided with a limiting device.

[0007] The intelligent operation area, storage bin, and discharge system area are all equipped with an outer shell, and the outer shell has T-shaped strips on the edges. The T-shaped strips between adjacent modules are connected by plug-in symmetrical I-beam profiles.

[0008] The intelligent operation area includes a DCS control system; the storage silo is equipped with a weighing device; the discharge system area includes a discharge drive device, several quick-connect pipes, and is equipped with a pressure gauge and a flow controller.

[0009] In the aforementioned digital modular mobile feeding device, preferably, the digital operation area, storage bin, and discharge system area are respectively equipped with wire and pipe quick-connect modules; the wire and pipe quick-connect modules include elastic winding devices for coiling wires and pipes.

[0010] In the aforementioned modular mobile feeding device, preferably, the discharge drive device is a pneumatic pump, an electric pump, or an external pressure nitrogen input device; the discharge system area has several quick-connect pipes, including a first functional pipe and a second functional pipe.

[0011] In the aforementioned modular mobile feeding device, preferably, the pneumatic pump or electric pump is connected to the storage silo via a first regulating valve and an extraction pipe, and the pneumatic pump or electric pump is connected to the discharge port via a check valve, a flow controller and an output pipe; and the extraction pipe is connected to the output pipe after the check valve via a second regulating valve.

[0012] In the aforementioned modular mobile feeding device, preferably, the discharge port is connected to a first functional pipe, which is connected to a storage bin; one end of the second functional pipe is connected to the storage bin, and the other end of the second functional pipe is connected to an external venting system.

[0013] In the aforementioned digital intelligent modular assembly mobile feeding device, preferably, the symmetrical I-beam profile has constriction grooves on both sides of the "I" shape, and the constriction of the constriction grooves eliminates the degree of freedom of the T-shaped strip on the edge of the outer shell along the radial direction of the symmetrical I-beam profile.

[0014] In the aforementioned digital modular mobile feeding device, preferably, the limiting device on the chute has a rubber shock absorber that matches the depth of the chute and a handle located above the plane of the chute.

[0015] In the aforementioned digital modular mobile feeding device, preferably, the digital operation area is equipped with feeding time, feeding amount, and real-time temperature, pressure, liquid level, and weight parameters of the material in the storage bin, and is also equipped with a rechargeable battery.

[0016] In the aforementioned digital modular mobile feeding device, preferably, the storage silo is equipped with a temperature, pressure, and liquid level data collection device connected to the digital operation area.

[0017] This technical solution, based on the characteristics of reactor feeding in the pharmaceutical and chemical industry, uses a mobile vehicle as a carrier and incorporates a digital operation module. Raw material drums or movable containers are quickly and securely placed in the storage silo on the mobile vehicle. The storage silo is equipped with a weighing device and displays real-time parameters such as material temperature, pressure, level, and weight. The digital operation module then displays these parameters and enables efficient operation. Simultaneously, a discharge system is installed on the mobile vehicle, facilitating the feeding of material drums or movable containers.

[0018] The main functional areas of this device—the intelligent operation area, storage silos, and discharging system area—are rapidly assembled on a mobile vehicle using modular assembly. This allows for material transfer to storage silos of different capacities, facilitating device maintenance. Each modular assembly is equipped with quick-connect modules for electrical wires and pipes, which allow for easy storage and withdrawal of the pipes through flexible coiling.

[0019] This device is also equipped with a multi-functional quick-connect pipe assembly, which can perform various material transfer processes, such as transferring materials from an external raw material tank to a movable container, or feeding materials from a movable container to a reactor, or directly feeding materials from a raw material tank to a reactor. Different process operations can be performed simply by pulling out the quick-connect fitting and connecting or disconnecting it to the pipe opening provided in the storage silo or the point of use.

[0020] Furthermore, during operation of this device, whether the raw material tank or the movable metering container is feeding the reactor, the connection method of the extraction pipe remains unchanged. As long as the pump output pipe is connected to the first functional pipe, the first functional pipe is connected to the inlet of the raw material tank or the movable metering container, and then the exhaust port of the raw material tank or the movable metering container is connected to the second functional pipe, which is connected to the external venting system, the storage silo can be sealed for loading without exhaust gas discharge, which is environmentally friendly and pollution-free.

[0021] The discharge system of this device consists of a discharge drive unit—a pump—and a multi-functional quick-connect pipe. The discharge drive unit can be a power pump or, depending on the available energy supply, directly connected to pressurized nitrogen. The pump's pressure, flow rate, and other parameters are displayed and controlled by a digital operation module. Directional feeding can also be controlled directly by the weighing system of the storage silo, making operation flexible, convenient, and easy to understand.

[0022] Compared with existing technologies, the advantages of this utility model are as follows: it integrates various functions of feeding the reactor, such as storage, transfer, feeding, and metering, into a mobile vehicle, realizing fixed-point, quantitative, and one-stop feeding operations. It can move and position quickly to adapt to different production scenarios; it automates the feeding process, reduces manual intervention, and improves production efficiency; the weighing device and flow controller ensure the accuracy of material addition, meeting the needs of high-precision production; the modular assembly method meets the needs of different raw material usage, and the quick-connect module design simplifies the installation and disassembly process of the equipment, improving work efficiency and ensuring safety and reliability.

Detailed Implementation

[0033] The technical solution of this utility model will be further described in detail below through embodiments and with reference to the accompanying drawings. This embodiment provides a digital intelligent modular assembled mobile feeding device, such as... Figure 1 As shown, a four-wheeled mobile vehicle 1 is provided. The mobile vehicle 1 consists of a push handle, a push chassis, omnidirectional push wheels, etc. The push handle uses an existing brake switch mechanism. During operation, the operator pushes the mobile vehicle 1 to the designated position by pressing down to unlock the push brake. After reaching the designated position, the operator releases the handle to automatically brake and lock the wheels.

[0034] Three main functional areas are set up on the mobile vehicle 1 using a modular assembly method, such as Figure 3 As shown: Digitalized operation area 2, storage bin 3, and discharge system area 4. The modular assembly method includes a chute 102 located on the mobile vehicle chassis 101, see [reference needed]. Figure 5 , Figure 6 , Figure 7 The bottom of the digital operation area 2, storage bin 3, and discharge system area 4 are all equipped with slide rails 302 that cooperate with the chute 102. The chute 102 is a double smooth groove that is sunken into the plane of the mobile vehicle chassis 101. The slide rails 302 are double rails with smooth surfaces that protrude from the bottom of each functional area. The double rails have high stability and do not affect the disassembly and placement of individual functional areas.

[0035] The chute 102 is equipped with a limiting device 7 that works in conjunction with it, such as... Figure 9 As shown, the limiting device 7 has a rubber shock absorber that fits the depth of the groove 102 and a handle located above the plane of the chute 102. The rubber shock absorber can increase friction and prevent the functional areas after positioning from moving along the length of the chute 102. The handle is used for assembly personnel to operate.

[0036] The intelligent operation area 2, storage silo 3, and discharging system area 4 are all equipped with outer shells, such as Figure 3 , Figure 4 As shown, the outer shell has T-shaped strips on its edges, which are arranged laterally along each functional module (i.e., laterally along the mobile chassis 101). Each functional module has one side at the top, bottom, front, and rear, for a total of four sides. The T-shaped strips between adjacent functional modules are connected by insert-type symmetrical I-beam profiles 6. The symmetrical I-beam profile 6 has a structure with constricted grooves on both sides of the "I" shape. The constriction of the grooves eliminates the degree of freedom of the T-shaped strips on the outer shell edges along the radial (lateral) direction of the symmetrical I-beam profile 6, ensuring that the T-shaped strips of adjacent functional modules are completely connected into one piece through the symmetrical I-beam profile 6.

[0037] The intelligent operation area 2, storage silo 3, and discharging system area 4 are each equipped with quick-connect modules 5 for electrical wires and pipes, such as... Figure 8 As shown, the quick-connect module 5 for wires and pipes includes an elastic winding device for coiling wires and pipes. The quick-connect module 5 performs the winding and pulling operations of the wires and pipes through elastic coiling.

[0038] The intelligent digital operation area 2 includes a DCS control system, or distributed control system, which can achieve centralized monitoring and decentralized control through network connection, reducing human intervention, improving production efficiency, lowering operating costs, and facilitating maintenance. The intelligent digital operation area includes settings for parameters such as feeding time, feeding amount, and real-time temperature, pressure, level, and weight of materials in the storage silo, and is equipped with rechargeable batteries. The intelligent digital operation area 2 has an operation panel 201 that centrally displays various parameter information, including temperature, pressure, level, and weight displays required by each functional area, such as pump outlet pressure display. If an electric pump is used, it will display start, stop, running, and fault signal displays; if a pneumatic pump is used, it will also display the inlet air pressure, etc.

[0039] The storage bin 3 is equipped with a weighing device. The storage bin 3 can hold raw material barrels or movable containers 301. Raw material barrels can be directly placed into the storage bin 3. The inlet and outlet of the raw material barrels or movable containers 301 are connected by wires and pipe quick-connect modules 5. It is also equipped with data sensing devices such as temperature, pressure and liquid level that are connected to the intelligent operation area 2.

[0040] The discharge system area includes a discharge drive unit and is equipped with a pressure gauge and flow controller, such as... Figure 2 As shown, the quick-connect fitting includes a first functional pipe 403 and a second functional pipe 404. The discharge drive device is a pneumatic pump 401 or an electric pump, or it can be directly connected to a pressure nitrogen input device from the outside, allowing for flexible use. The pneumatic pump 401 or electric pump can be supplied with a gas source or a specific explosion-proof power socket at the location of use. When operating the raw material drum or movable container 301, the pressure gauge and flow control system are connected to the intelligent operation area 2 for display and operation. When transferring material from a raw material drum other than the mobile vehicle 1 to the movable container 301, the weighing device equipped in the storage bin 3 can be directly controlled to complete the directional feeding.

[0041] Furthermore, the pneumatic pump 401 or electric pump in the discharge system area is connected to the raw material barrel or movable container 301 placed in the storage bin 3 via the first regulating valve 407 and the extraction pipe 408. The pneumatic pump 401 or electric pump is led to the discharge port via the check valve 406, the flow controller and the output pipe 402. At the same time, the extraction pipe 408 is connected to the output pipe 402 after the check valve 406 via the second regulating valve 405.

[0042] To further enable multiple material transfer and feeding functions, the discharge port and one end of the first functional pipe 403 are connected via quick-connect couplings provided by the wire and pipe quick-connect module 5. Similarly, the other end of the first functional pipe 403 and the storage silo 3, as well as one end of the second functional pipe 404 and the storage silo 3, are connected via quick-connect couplings. The other end of the second functional pipe 404 is connected to an external venting system. The first functional pipe 403 and the second functional pipe 404 have the same function and are interchangeable.

[0043] Working principle and specific implementation methods:

[0044] Example 1: Assembly and installation of functional area modules. Using the chute 102 on the mobile vehicle chassis 101, align the bottom slide rail 302 of the intelligent operation area 2 module with the chute 102, positioning the intelligent operation area 2 module at the end of the mobile vehicle 1 near the handrail. Note: The end of the chute 102 near the handrail is a blind end. Then, using the same method, position the storage bin 3 in the middle of the mobile vehicle 1. Next, position the discharge system area 4 adjacent to the storage bin 3 on the mobile vehicle 1, and insert the upper limit device 7 at the end of the chute 102. Then, use symmetrical I-beams 6 to connect the T-shaped strips between adjacent modules into a single unit. The ends of the assembled symmetrical I-beams 6 and T-shaped strips can be secured with soft rubber plugs. In this example, if a different specification of storage bin 3 is to be replaced, simply remove the upper limit device 7, then move the discharge system area 4, leaving the corresponding length of the storage bin 3, and replace it with the storage bin 3.

[0045] Because of the quick-connect module 5 for wires and pipes, after each functional area is located, the corresponding pipes and wires can be pulled out for connection when in use, and the pipes and wires can be unplugged and returned to their original positions when stored.

[0046] Example 2: When transferring material directly from the raw material barrel to the movable container 301, the extraction pipe 408 is quickly connected to the raw material barrel with material outside the device, and the discharge port of the output pipe 402 is connected to the first functional pipe 403 or the second functional pipe 404. The first functional pipe 403 or the second functional pipe 404 is connected to the empty raw material barrel or the empty movable container 301 placed in the storage bin 3. The weighing device in the storage bin 3, combined with the DCS control system of the digital operation area 2, performs directional and quantitative feeding.

[0047] Example 3: When transferring materials from the raw material barrel outside the device to the movable container 301 in a sealed manner without exhaust gas discharge, the extraction pipe 408 is connected to the source of the raw material, the discharge port of the output pipe 402 is connected to the first functional pipe 403, the first functional pipe 403 is connected to the first interface on the top of the movable container 301 inside the storage bin 3, the second interface on the top of the movable container 301 is connected to the second functional pipe 404, and the second functional pipe 404 is connected to the external venting system. This achieves sealed loading of materials into the movable container 301 without exhaust gas discharge, which is environmentally friendly and pollution-free.

[0048] Example 4: When feeding material from the raw material barrel or movable container 301 into the reactor, the extraction pipe 408l is connected to the raw material barrel or the movable container 301 with raw material in the storage bin 3. The mobile vehicle 1 is moved to the designated feeding location. The discharge port of the output pipe 402 is connected to the reactor feed pipe. The feeding amount, feeding speed and other parameters are controlled by the DCS control system of the intelligent operation area 2.

[0049] Additionally, in the event of a malfunction of the configured pneumatic pump 401 or electric pump, one end of the external nitrogen gas supply pipe is connected to one end of the first functional pipe 403 via a quick-connect coupling, and the other end of the first functional pipe 403 is connected to the storage silo 3 via a quick-connect coupling. The extraction pipe 408 is connected to the raw material barrel or movable container 301 placed inside the storage silo 3. By closing the first regulating valve 407 and opening the second regulating valve 405, normal feeding can be achieved through the output pipe 402.

[0050] The above embodiments are illustrative of the present invention and not intended to limit it. Although the present invention has been described in conjunction with preferred embodiments, it should be understood that the present invention is not limited to the preferred embodiments. Those skilled in the art can make various equivalent modifications and substitutions to the technical solutions of the present invention based on its teachings. Therefore, the scope of the present invention should be defined by the claims, and all such equivalent modifications and substitutions fall within the protection scope of the present invention.
