Problems solved by technology

[0005] The above three filling methods have disadvantages: plunger filling cannot realize in-place cleaning (SIP for short); peristaltic pumps are expensive and difficult to use for multi-head filling; The characteristics of filling are fast filling speed and simple device structure. However, due to the difficulty of micro-pressure control, and the fluctuation of filling pressure has a great influence on the stability of filling volume, the filling accuracy of small doses is low, and the current time pressure Filling method is mainly used for large-dose filling

Embodiment Construction

[0023] In order to make the present invention more comprehensible, preferred embodiments are described in detail below with accompanying drawings.

[0024] like Figure 1 to Figure 3 As shown, a constant pressure device provided by the present invention includes a buffer tank and pressure supplement and discharge components connected thereto. The buffer tank includes a lower tank body 1 and an upper tank body 2 arranged up and down, and the lower tank body 1 and the upper tank body 2 After docking, the tank body is formed by the clamp 4, and a sealing ring 3 is provided on the butt joint surface of the lower tank body 1 and the upper tank body 2. One end of the liquid replenishment pipe 11 stretches into the tank body. After passing through the upper tank body 2, it extends into the lower tank body 1. The liquid replenishment pipe 11 goes deep into the tank body to prevent splashing and foam generation in the liquid replenishment process. The other end of the liquid replenishm...

Abstract

The invention relates to a constant pressure device, and the device comprises a buffer tank and a pressure-supplementing and pressure-discharging component. The constant pressure device is characterized in that, the buffer tank comprises a lower tank arranged below and an upper tank arranged above, and the lower tank and the upper tank are connected together in a butt joint way, forming a tank body via a lathedog; a sealing ring is disposed on the butt joint surface of the lower tank and the upper tank; one end of a fluid-supplementing tube is inserted into the tank body, and the other end sticks out of the tank body; a spray apparatus is disposed in the upper tank, and an inlet of the spray apparatus sticks out of the tank body; the upper tank is communicated with the pressure-supplementing and pressure-discharging component, and the bottom of the lower tank is communicated with a filling tube; and a filling pressure transducer for obtaining filling pressure is disposed at the filling tube. The constant pressure device of the invention has the advantages of: simple structure, easy disassembly and assembly, high stability, and SOP / SIP compatibility.

Description

technical field [0001] The invention relates to a constant pressure device used in a filling linkage line, belonging to the technical field of packaging equipment for food, medicine and cosmetics. Background technique [0002] In the existing filling structure, three filling methods are generally adopted: plunger filling, peristaltic pump filling, and time pressure filling. For example, the application number is CN200720110152, and the Chinese patent titled "Plunger Type Quantitative Filling Device" discloses a device that adopts plunger type filling, including a stepping motor fixed in the frame and driven by the stepping motor. The mechanism drives the rotating turntable. The turntable is equipped with an adjustable bottom block. The bottom block is connected to the plunger. The rotation of the turntable drives the plunger to make a reciprocating linear motion. Pipe and discharge pipe, the discharge pipe is connected to the injection nozzle, the filling material enters th...
