Technical Field

[0001] This utility model relates to the technical field of liquid addition equipment in industrial production processes, specifically a portable liquid dispensing device. Background Technology

[0002] Currently known liquid filling devices consist of fixed pumps and tanks to complete the liquid filling needs. These devices have drawbacks such as low load capacity, inflexible movement, short service life, and poor mechanical performance, making it difficult to meet the liquid filling needs of modern industrial production processes. Summary of the Invention

[0003] To overcome the shortcomings of the existing technology, the purpose of this invention is to provide a mobile liquid filling device to achieve flexible movement and transportation during the liquid filling process, as well as a long lifting range.

[0004] To achieve the above-mentioned objectives, the present invention provides a portable liquid filling device comprising a liquid tank and a movable base. The liquid tank is divided into two compartments by a partition. The larger compartment is a sealed space that can hold liquid, and the smaller compartment is equipped with a single-phase jet pump. A fire hose reel is located on the back of the rear door. The top of the liquid tank has a liquid inlet. The liquid inlet of the single-phase jet pump is connected to the liquid suction port of the liquid tank, and the liquid outlet of the single-phase jet pump is connected to the liquid inlet of the fire hose reel.

[0005] Furthermore, the liquid tank is made of stainless steel plate; the upper flange of the filter mesh 1.3 is positioned on the liquid inlet 1.2, which faces the large chamber of the liquid tank; the large sealing cover is connected to the external threaded post of the liquid inlet through the threaded hole at its lower end, and a large sealing ring is provided on the upper end face of the threaded hole of the large sealing cover; the threaded hole of the small sealing cover is connected to the external threaded post at the upper end of the large sealing cover, and a small sealing ring is provided on the upper end face of the threaded hole of the small sealing cover; lifting rings are welded at the four corners of the upper part of the liquid tank; a suction port is opened at the bottom of the liquid tank near the partition; a pair of rear doors are installed on the rear side of the liquid tank, which are connected to the side plate of the liquid tank by hinges and are closed by locks; a handle is installed on the front side of the liquid tank; an observation window is provided on the side of the liquid tank, which is sealed to the liquid tank by plexiglass and a sealing ring.

[0006] Furthermore, the single-phase jet pump is connected to the bottom of the rear side of the liquid tank via a base. The inlet of the single-phase jet pump is connected to the suction port of the liquid tank via a hose, and the outlet of the single-phase jet pump is connected to the inlet of the hose of the fire hose reel via a quick-connect adapter. The model of the single-phase jet pump is JET1100A.

[0007] Furthermore, the threaded hole at one end of the inlet pipe of the quick-connect adapter is threadedly connected to the outlet connector of the single-phase jet electric pump, and the two outlets of the inlet pipe are respectively connected to outlet pipe one and outlet pipe two of different diameters. Outlet pipe one or outlet pipe two is connected to the inlet port of the hose that is compatible with it.

[0008] Furthermore, the center of the fire hose reel is mounted on the back of the rear door via a hollow shaft and locked with a lock nut. The rotary joint is threadedly connected to the middle pipe opening of the fire hose reel. The rotary joint is connected to the outlet of the single-phase jet pump via a hose. The hose is wound around the fire hose reel and extends outward through the outlet of the fire hose reel. Four rollers are provided at the outlet of the fire hose reel. The model of the fire hose reel is JPS0.8-19 / 25.

[0009] Furthermore, the movable base includes a base frame with four legs mounted on its lower side. Two fixed wheels are mounted on the lower front of the base frame via a fixed seat. The fixed side of the flip hinge is mounted on the fixed seat, and the movable side is fixedly connected to the inner side bracket of the fixed wheels. A locking device is provided between the bracket above the fixed wheels and the fixed seat. The movable side of the flip hinge is also fixedly connected to one end of a tension spring via a hook mounted on the inner side bracket of the fixed wheels. The other end of the tension spring is fixedly connected to a hook located in the lower center of the base frame. Two omnidirectional wheels are mounted on the lower rear of the base frame via a fixed seat. The fixed side of the flip hinge is mounted on the fixed seat, and the movable side is connected to the inner side bracket of the omnidirectional wheels. A locking device is provided between the bracket above the omnidirectional wheels and the fixed seat. The movable side of the flip hinge is also connected to one end of a tension spring via a hook mounted on the inner side bracket of the omnidirectional wheels. The other end of the tension spring is connected to a hook located in the lower center of the base frame.

A spring is fitted on the locking rod, with one end of the spring pressing against the upper end face of the inner hole of the sleeve and the other end pressing against the stepped shaft of the locking rod. The locking rod is adapted to the hole on the outer side of the fixing wheel and swivel wheel bracket.

[0011] Compared with existing technologies, this invention, in its transport state, involves lifting the locking lever upwards and moving the four wheels inwards, causing them to rotate 90° inwards. The four wheels automatically retract, and the four outriggers land on the ground, ensuring the device is stable and resistant to shaking during transport. When the device needs to operate, the four wheels are moved outwards, and the locking lever is pressed down, locking the wheel brackets to the fixed base. The entire device can then be manually moved, making it flexible for movement and transport. It employs a single-phase jet pump with a head of up to 48m. When used in conjunction with a fire hose reel, the head fully meets the liquid filling requirements. This invention has a simple structure, long service life, and good mechanical properties, and can be widely used in industrial production processes for water or other liquid filling, agricultural and planting irrigation, and other applications.
