Embodiment 1

[0032] Such as figure 1 As shown, in this embodiment, the food high-pressure pump pulsation reduction device includes a housing 1 with a housing space, an air bag 2, an inflator 3 and a connecting device 4. The housing 1 is a cylindrical structure, and both ends are provided with There are connecting devices 4, respectively connected to the inlet and outlet of the material of the production system, the airbag 2 is arranged in the housing 1, and its two ends communicate with the connecting devices 4 at the two ends of the housing 1 respectively A closed air chamber 5 is formed between the inner wall of the housing 1 and the air bag 2 , the inflator 3 is arranged on the side wall of the housing 1 , and the air chamber 5 communicates with the inflator 3 .

[0033] In this embodiment, in order to ensure the pressure bearing capacity and service life of the high-pressure pulsation buffer, the aspect ratio of the housing 1 is greater than 5, and the ratio of the outer diameter to th...

Embodiment 2

[0037] Such as figure 2 As shown, in this embodiment, the inflation device 3 includes an inflation valve 3-1 and a pressure gauge 3-2, and the inflation valve 3-1 is fixedly arranged on the side wall of the housing 1 and connected to the 5, the other end of the inflation valve 3-1 communicates with the gas source through the inflation tube, and the pressure gauge 3-2 is arranged on the inflation tube.

[0038]In this embodiment, the connection device 4 includes an infusion tube 4-1 and a flange 4-2, one end of the infusion tube 4-1 is fixedly connected to the end of the housing 1 and connected to the airbag 2 communicates internally, and its other end is fixedly connected to the mounting hole provided at the center of the flange 4-2 and passing through the flange 4-2.

[0039] In this embodiment, the housing 1 is further provided with a safety valve 6 connected to the air chamber 5 .

[0040] In this embodiment, the connecting device 4 is connected in a way of flange butt j...

Embodiment 3

[0045] Such as Figure 3 to Figure 4 As shown, in this embodiment, the airbag 2 is sleeved with a flow stabilizer 7, and the flow stabilizer 7 includes a cylinder body 7-1 with a straight structure, and the two ends of the cylinder body 7-1 are respectively connected to the The infusion tube 4-1 at both ends of the housing 1 is fixedly connected, and the side wall of the cylinder body 7-1 is evenly distributed with a number of through holes penetrating the cylinder wall, and the inner middle position of the cylinder body 7-1 is transversely perpendicular to the cylinder wall. The wall is fixedly provided with a stabilizing plate 7-2, and several through holes are uniformly arranged on the stabilizing plate 7-2.

[0046] In this embodiment, the flow stabilizer 7 is set so that when the airbag 2 expands and contracts, the liquid material needs to pass through the through hole on the cylinder wall of the cylinder 7-1, so as to achieve the effect of slowing down the flow rate, and...

Abstract

The invention relates to the technical field of food processing equipment, in particular to a pulsation reducing device of a food high-pressure pump. The pulsation reducing device comprises a shell with an accommodating space, a gasbag, a gas filling device and connecting devices, wherein the shell is of a barrel-shaped structure, and the two ends of the shell are equipped with connecting deviceswhich are separately connected with a material inlet and a material outlet of a production system; the gasbag is arranged in the shell, and the two ends of the gasbag separately communicate with the connecting devices at the two ends of the shell; a sealed gas chamber is formed between the inner wall of the shell and the gasbag; the gas filling device is arranged on the side wall of the shell; andthe gas chamber communicates with the gas filling device. The pulsation reducing device adopts an independent inlet and outlet channel, is free of a dead corner inside, enables materials to not stayfor a long time in the gasbag to avoid colony breeding, and is safe and reliable.

Description

technical field [0001] The invention relates to the technical field of food processing equipment, in particular to a pulsation reducing device for a high-pressure food pump. Background technique [0002] At present, in the food high-pressure pulse system, the pressure pulsation caused by the pressure difference at the moment of liquid absorption by the plunger of the high-pressure pump can cause pressure fluctuations in front of the high-pressure spray nozzle, resulting in instability of the pressure spray system, resulting in changes in the spray particle size, affecting Product granularity and performance. Therefore, it is necessary to connect a pulsation damper between the pump outlet and the pressure nozzle. The purpose is to eliminate pressure pulsations at the outlet of the high pressure pump. [0003] At present, the high-pressure pump pulsation buffers produced by various companies include resonant cavity type, adjustable spring type, online metal ring type and T-s...
