Air injector for milking plants

Abstract

Air injector (10) for milking plants comprising a lower body (11) having an air inlet opening (12) for inletting air into the milking plant; a membrane (14) supportedly mounted on the air inlet opening (12); a tight-sealed lower chamber (25) inferiorly delimited by the membrane (14) and superiorly delimited by an upper body (15); a coil (23) housed in the upper body (15) and comprising a mobile core (24) and a coil hole (26) connected to the outside; a tight- sealed upper chamber (35) which is formed in the upper body (15), is superiorly delimited by the coil (23) and is connected to the outside through the coil hole (26), wherein the upper body (15) comprises a first hole (29) communicating the upper chamber (35) with a vacuum duct (36) connected to a vacuum pipe of the milking plant, and wherein the upper body (15) comprises a second hole (30) formed in the upper chamber (35), wherein said second hole (30) leads into an annular connecting chamber (31) connected to the lower chamber (25), said mobile core being adapted to move from a rest position, in which it closes the first hole (29) and opens the coil hole (26), to a position in which the mobile core (24) is lifted and opens the first hole (29) while closing the coil hole (26), so as to let air flow into or create vacuum in the upper chamber (35) and in the lower chamber (25) connected thereto in order to generate a movement of the membrane (14).

Description

technical field [0001] The invention relates to an air injector for a milking equipment for injecting air into the milking equipment during washing of said equipment. [0002] More specifically, the air injectors are arranged to cause a controlled amount of air to flow into the milking equipment to create turbulence in the wash liquor for the equipment. Background technique [0003] In the field of milking equipment technology it is known to use air jets to obtain a thorough cleaning of milking equipment. [0004] In dairy farms, thorough cleaning of the equipment after its use is considered fundamental for the protection of equipment components, milking hygiene and the health of animals that come into contact with parts of the equipment. [0005] In order to be able to properly and effectively wash the equipment, in addition to using a washing solution having the appropriate characteristics in terms of the concentration of detergent or acid and the temperature of the water...

AI Technical Summary

Problems solved by technology

[0009] However, devices of the type described above have various drawbacks

[0010] One of the disadvantages is that it is difficult to obtain a fast movement of the membrane, for example, during its cyclic washing, periodically injecting small amounts of air into the pipes of the equipment at a high frequency, thus creating a high concentration of the washing liquid for the equipment. turbulent motion

[0011] Another drawback is the high energy consumption required for the rapid movement of the film

[0012] A further disadvantage is that the device has large external dimensions, which complicate its installation, especially on particularly compact devices
