Description

Technical Field

[0001] This utility model relates to the field of pressure relief valve technology, and in particular to a pressure relief silencer for ultra-high pressure sterilization. Background Technology

[0002] Ultra-high pressure sterilization equipment refers to equipment that uses ultra-high pressure (400-600 MPa) technology to sterilize food. The process of releasing pressure from the ultra-high pressure state in an ultra-high pressure sterilization equipment in a short time is called pressure relief. Ultra-high pressure sterilization equipment is equipped with a pressure relief device. The main function of the pressure relief device is to keep it closed when the ultra-high pressure sterilizer needs to increase or maintain pressure, and to open it when the pressure holding ends or in case of an emergency, so that the ultra-high pressure sterilizer can release pressure quickly.

[0003] Existing ultra-high pressure sterilization equipment typically releases pressure by directly discharging into the water tank. Due to the high pressure of the ultra-high pressure sterilizer, the water flow rate is extremely fast during pressure release. The high-speed water jet carries enormous energy, impacting the water tank and the water inside. Even if the pressure relief water pipe is below the water surface in the tank, it will still generate tremendous noise.

[0004] Therefore, how to reduce the flow rate of high-pressure water to achieve noise reduction is a technical problem that needs to be solved by those skilled in the art. Utility Model Content

[0005] The purpose of this invention is to provide a pressure relief silencer for ultra-high pressure sterilization, which can reduce the flow rate of high-pressure water and thus reduce noise.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A pressure relief silencer for ultra-high pressure sterilization includes:

[0008] The muffler body is a columnar structure with an inlet chamber inside. The opening of the inlet chamber is provided with an internal thread for connection with a threaded sleeve on the pressure relief pipeline. The side wall of the muffler body is provided with several pressure relief outlet holes, which are connected to the pressure relief pipeline through the inlet chamber.

[0009] Preferably, the first end of the muffler body is provided with a clamping plane, which is used to facilitate the installation and fastening of the muffler body.

[0010] Preferably, the first end of the muffler body is provided with two clamping planes, and the two clamping planes are symmetrical about the axis of the muffler body.

[0011] Preferably, the water inlet chamber has a columnar structure, and its axis coincides with the axis of the muffler body;

[0012] The pressure relief outlet is a through hole with a circular cross-section, and its axis is perpendicular to the axis of the water inlet cavity.

[0013] Preferably, the intervals between the pressure relief outlet holes are equal along the axial direction of the silencer body.

[0014] Preferably, several of the pressure relief devices are evenly distributed on the periphery of the muffler body.

[0015] Preferably, the first end of the muffler body is provided with a connecting groove communicating with the water inlet cavity. The connecting groove has a columnar structure and its diameter is larger than the diameter of the water inlet cavity. The internal thread is provided on the inner wall of the connecting groove.

[0016] Preferably, the water inlet cavity is formed by drilling.

[0017] Preferably, the main body material of the muffler is stainless steel.

[0018] Compared with the above background technology, the present invention provides a pressure relief silencer for ultra-high pressure sterilization, comprising: a silencer body with a columnar structure, wherein a water inlet chamber is provided inside, the opening of the water inlet chamber is provided with an internal thread, the internal thread is used to connect with a threaded sleeve on the pressure relief pipeline, and the side wall of the silencer body is provided with a plurality of pressure relief outlet holes, the pressure relief outlet holes being connected to the pressure relief pipeline through the water inlet chamber.

[0019] Specifically, the pressure relief pipeline is connected to the internal thread of the silencer body of this application through the pipe cap and threaded sleeve at its outlet end. After the connection is completed, the pressure relief pipeline will be connected to the water inlet chamber and then to the pressure relief outlet. When the pressure is released, the ultra-high pressure water passes through the water inlet chamber of the silencer body, the flow rate decreases and the energy is reduced, and then it flows out from the pressure relief outlet and is quickly absorbed by the water in the water tank, thereby achieving the function of reducing noise.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] To enable those skilled in the art to better understand the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0033] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left" and "right" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the indicated position or element must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations of this utility model.

[0034] The purpose of this utility model is to provide a silencer for ultra-high pressure sterilization. It is designed in combination with the characteristics of the pressure relief pipeline and the compatibility with the silencer to solve the problem of high noise when the ultra-high pressure sterilizer is depressurized in the prior art. The silencer in this application is connected to the original pressure relief pipeline. After the ultra-high pressure water flowing out of the pressure relief pipeline passes through the silencer, the flow rate of the high pressure water can be significantly reduced, the energy of the water flow can be released, and the noise can be reduced.

[0035] To achieve the above objectives, the present invention provides the following technical solution:

[0036] Please see Figures 1 to 3This embodiment provides a pressure relief silencer for ultra-high pressure sterilization, comprising: a silencer body 100 with a columnar structure, wherein a water inlet chamber 200 is provided inside, and an internal thread 310 is provided at the opening of the water inlet chamber 200. The internal thread 310 is used to connect with a threaded sleeve 02 on the pressure relief pipeline 01. A plurality of pressure relief water outlet holes 400 are provided on the side wall of the silencer body 100, and the pressure relief water outlet holes 400 are connected to the pressure relief pipeline 01 through the water inlet chamber 200.

[0037] Specifically, the silencer body 100 is a cylindrical structure with an inlet chamber 200 inside. The inlet chamber 200 has only one inlet with an internal thread 310. It should be noted that the internal thread 310 is used to connect with the threaded sleeve 02 on the pressure relief pipe 01. Therefore, the size of the internal thread 310 can be adjusted appropriately according to actual needs. The internal thread 310 allows operators to quickly connect or disconnect the silencer body 100 and the pressure relief pipe 01. This allows the silencer to be installed at the outlet of the pressure relief pipe 01 when silence is needed, and the two can be disassembled and stored separately when not needed.

[0038] In this embodiment, the silencer body 100 is placed inside a water tank during use. Several pressure relief outlet holes 400 are provided on its side wall. The distribution, spacing, and cross-sectional shape of these pressure relief outlet holes 400 can be adjusted appropriately according to actual conditions. The pressure relief outlet holes 400 are connected to the water inlet chamber 200. In this way, the high-speed water discharged from the pressure relief pipe 01 can first enter the water inlet chamber 200 and then be discharged through the pressure relief outlet holes 400, and quickly absorbed by the water in the water tank.

[0039] like Figure 3 As shown, in the installed state, the outlet end of the pressure relief pipe 01 is connected to the threaded sleeve 02 through the pipe cap 03, and the threaded sleeve 02 is threaded to the internal thread 310, thereby realizing the quick connection and disassembly of the pressure relief pipe 01.

[0040] In other words, the pressure relief pipe 01 is connected to the internal thread 310 of the silencer body 100 of this application through the screw sleeve 02 at its outlet end. After the connection is completed, the pressure relief pipe 01 will be connected to the water inlet chamber 200 and then to the pressure relief outlet 400. When the pressure is released, the ultra-high pressure water passes through the water inlet chamber 200 of the silencer body 100, the flow rate decreases and the energy decreases, and then flows out from the pressure relief outlet 400 on the side wall of the silencer body 100 and is quickly absorbed by the water in the water tank, thereby achieving the function of reducing noise.

[0041] Preferably, the first end 110 of the muffler body 100 is provided with a clamping plane 500, which is used to facilitate the installation and fastening of the muffler body 100.

[0042] Understandably, the muffler body 100 is a cylindrical structure with an arc-shaped circumference, which makes it inconvenient to clamp the muffler body 100. Therefore, in this embodiment, the first end 110 of the muffler body 100 is provided with a clamping plane 500; specifically, as shown... Figure 1 and Figure 2 As shown, the clamping plane 500 is the plane created by cutting off a portion of the end of the muffler body 100. This design allows the muffler body 100 to be easily clamped with a wrench when it is installed, preventing relative sliding between the muffler body 100 and the wrench, and also avoiding damage to the muffler body 100 due to excessive wrench tightening force.

[0043] In addition, to make the installation of the muffler body 100 easier and more convenient, in this embodiment, the first end 110 of the muffler body 100 is the end where the water inlet chamber 200 is set. In this way, the clamping plane 500 serves as the force-bearing surface, and its proximity to the internal thread 310 makes it easier to install the connection between the internal thread 310 and the nut.

[0044] Preferably, the first end 110 of the muffler body 100 is provided with two clamping planes 500, which are symmetrical about the axis of the muffler body 100.

[0045] Furthermore, in order to ensure that the muffler body 100 fits better with wrenches or other fastening tools during installation, two clamping planes 500 are symmetrically provided at the first end 110 of the muffler body 100. This can prevent uneven force on the muffler body 100 during clamping.

[0046] Preferably, the water inlet chamber 200 has a columnar structure, and its axis coincides with the axis of the muffler body 100; the pressure relief outlet 400 is a through hole with a circular cross-section, and its axis is perpendicular to the axis of the water inlet chamber 200.

[0047] Specifically, such as Figure 2 As shown, in this embodiment, the water inlet cavity 200 is a cylindrical cavity structure with a closed lower end and an open upper end, and its axis coincides with that of the muffler body 100, thereby reducing the processing difficulty. In addition, in this embodiment, the pressure relief outlet hole 400 is also set as a through hole with a circular cross-section. This setting can reduce the processing and manufacturing difficulty of the pressure relief outlet hole 400, thereby reducing the overall processing and manufacturing difficulty and cost of the muffler. At the same time, for the overall aesthetics of the muffler and to facilitate the drainage of the water inlet cavity 200, the pressure relief outlet holes 400 in this embodiment are all opened perpendicular to the axis of the muffler body 100. This setting can avoid interference between the pressure relief outlet holes 400 when processing them, and can reduce the processing and manufacturing difficulty of the muffler body 100.

[0048] Preferably, the intervals between several pressure relief outlet holes 400 in the axial direction of the silencer body 100 are equal.

[0049] Specifically, such as Figure 1 and Figure 2 As shown, in this embodiment, a plurality of pressure discharge holes 400 are provided on the circumferential surface of the silencer body 100, and the interval between each adjacent row is the same.

[0050] Furthermore, several pressure relief devices are evenly distributed on the circumference of the muffler body 100.

[0051] Furthermore, in this embodiment, the spacing between the pressure relief outlet holes 400 arranged in each row on the circumference of the silencer body 100 is also the same.

[0052] This design ensures that the pressure relief outlet holes 400 are evenly distributed both axially and circumferentially, which not only improves the aesthetics of the silencer body 100 but also enhances the noise reduction effect.

[0053] Preferably, the first end 110 of the muffler body 100 is provided with a connecting groove 300 communicating with the water inlet chamber 200. The connecting groove 300 has a columnar structure and its diameter is larger than the diameter of the water inlet chamber 200. An internal thread 310 is provided on the inner wall of the connecting groove 300.

[0054] In this embodiment, in order to more conveniently connect the muffler body 100 and the pressure relief pipe 01, a stepped connecting groove 300 relative to the water inlet chamber 200 is provided at the first end 110 of the muffler body 100, that is, at the opening of the water inlet chamber 200. The size of the connecting groove 300 can fit the size of the threaded sleeve 02 of the pressure relief pipe 01. In this embodiment, the internal thread 310 is provided on the inner wall of the connecting groove 300.

[0055] Preferably, the water inlet cavity 200 is formed by drilling.

[0056] In one embodiment, in order to reduce the processing difficulty, production time cost and economic cost of the muffler body 100, the water inlet cavity 200 can be directly formed by drilling.

[0057] Preferably, the muffler body 100 is made of stainless steel.

[0058] Understandably, in order to ensure the overall structural strength of the muffler, the muffler body 100 is preferably made of high-strength stainless steel, which also has corrosion resistance. Of course, other materials can be selected according to the actual situation, and this article does not limit them.

[0059] In summary, the silencer for ultra-high pressure sterilization provided in this paper is designed based on the existing high noise levels during pressure relief in ultra-high pressure sterilizers, combined with the characteristics of the pressure relief pipeline 01 and its compatibility with the silencer. The silencer body 100 is made of high-strength stainless steel and is connected to the internal thread 310 in the connecting groove 300 through the cap 03 and threaded sleeve 02 at the outlet end of the pressure relief pipeline 01. During connection, a wrench can be used to clamp the silencer on the clamping plane 500 at the top for easy tightening. During pressure relief, the ultra-high pressure water passes through the inlet chamber 200 in the silencer, where the flow rate decreases and the energy is reduced. Then, it flows out from the pressure relief outlet 400 and is quickly absorbed by the water in the water tank, thereby achieving the function of reducing noise.
