Description

Technical Field

[0001] The utility model relates to the technical field of homogenizer accessories, in particular to a cooling spray pipe for a homogenizer. Background Art

[0002] When the homogenizer is working, the plunger in the homogenizer makes a reciprocating linear motion to push the material to flow in a specified direction. Due to the work done by the linear motion of the plunger and the repeated friction between the plunger and the plunger seal, the plunger generates serious heat. Since the plunger will transfer heat to the material, the temperature of the material will increase, and this increase in the material temperature is not allowed by the process in most cases.

[0003] At present, an indirect spray cooling is usually adopted for the material by using a cooling spray pipe, that is, a medium with a large specific heat capacity such as water is used to reduce the material temperature through heat exchange. Please refer to the attached Figure 1 . The existing cooling spray pipe 1 is made of a steel pipe with an inner diameter of d. Small holes with apertures of d1, d2, and d3 are respectively set on the cooling spray pipe 1 as spray nozzles 2 according to the pressure drops caused by the frictional resistance along the way and the local resistance. Although the three spray nozzles 2 can make the output of the medium flow more uniform, its cooling effect is not ideal. The reasons are as follows:

[0004] 1. The phase intersection line formed by the spray nozzle 2 axially opened on the cooling spray pipe 1 and the cutting of the cooling spray pipe 1 is a three-dimensional line and surface intersection, and the curvatures of each point are different. For the fluid ejected from the spray nozzles 2 with different apertures, the normal direction of its particles is not consistent, and the direction of the fluid at the outlet is disordered and has no regular pattern to follow, resulting in an unstable cooling effect.

[0005] 2. In the heat exchange process, according to the heat balance equation, when the temperature difference is certain, the heat exchange effect is proportional to the mass of the fluid participating in the heat exchange. The more the mass of the fluid participating in the heat exchange per unit time, the more obvious the heat exchange effect and the higher the heat exchange efficiency. However, the existing cooling spray pipe cannot control the fluid beam, and the utilization rate of the fluid in the heat exchange process is very low, resulting in a poor actual cooling effect and often not meeting the use requirements.

[0006] Therefore, it is necessary to provide a cooling spray pipe for a homogenizer, which can solve the problem of poor cooling effect of the existing cooling spray pipe for a homogenizer. Summary of the Invention

[0007] The purpose of the utility model is to provide a cooling spray pipe for a homogenizer, which can solve the problem of poor cooling effect of the existing cooling spray pipe for a homogenizer.

[0008] The utility model is realized as follows:

[0009] A homogenizer cooling nozzle, comprising a main cooling spray pipe for the homogenizer and a cooling diversion branch pipe; one end of the main cooling spray pipe for the homogenizer is externally connected to a water supply source, and the other end of the main cooling spray pipe for the homogenizer is closed by a sealing plug; a number of communication holes are formed on the side wall of the main cooling spray pipe for the homogenizer, one end of each of the number of cooling diversion branch pipes is respectively connected to the main cooling spray pipe for the homogenizer through the communication holes, and the other ends of the number of cooling diversion branch pipes extend radially along the main cooling spray pipe for the homogenizer to the spray cooling position of the homogenizer.

[0010] The inner diameter of the main cooling spray pipe for the homogenizer is D, and D is greater than the inner diameter d of the cooling nozzle.

[0011] As a preferred embodiment, three communication holes are provided, the centers of the three communication holes respectively coincide with the centers of three nozzles on the cooling nozzle, and three cooling diversion branch pipes are correspondingly connected to the three communication holes.

[0012] The lengths of the three cooling diversion branch pipes are the same and are perpendicularly and fixedly connected to the main cooling spray pipe for the homogenizer.

[0013] The calibers of the ends of the three cooling diversion branch pipes far from the main cooling spray pipe for the homogenizer are D1, D2 and D3 respectively, and D1 is greater than the aperture d1 of the nozzle at its corresponding position, D2 is greater than the aperture d2 of the nozzle at its corresponding position, and D3 is greater than the aperture d3 of the nozzle at its corresponding position.

[0014] Compared with the prior art, the utility model has the following beneficial effects:

[0015] 1. Since the main cooling spray pipe for the homogenizer is provided in the utility model, the pipe diameter of the main cooling spray pipe for the homogenizer is larger than that of the traditional cooling nozzle. When the outlet pressure and flow rate of the output pump of the homogenizer are certain, the flow velocity and outlet pressure of the fluid medium can be reduced, the kinetic energy can be reduced, the spray effect and the sufficient heat exchange process can be ensured, which is beneficial to improving the heat exchange efficiency, thereby improving the cooling effect, and further reducing the equipment energy consumption while meeting the material cooling requirements.

[0016] 2. Since the cooling diversion branch pipe is provided in the utility model, the cooling diversion branch pipe plays a role in guiding the fluid medium, effectively constrains the fluid beam, enables the fluid medium to participate in the actual energy exchange process to the greatest extent, thereby maximizing the utilization rate of the fluid medium, and further being beneficial to improving the spray cooling effect.

[0017] 3. Since the present utility model is provided with cooling diversion branch pipes, the diameters of the three cooling diversion branch pipes are respectively larger than the apertures of the three nozzles at the same position in the traditional one. When the outlet pressure and flow rate of the output pump of the homogenizer are certain, it can reduce the flow velocity and outlet pressure of the fluid medium, reduce the kinetic energy, ensure the spraying effect and sufficient heat exchange process, which is conducive to improving the efficiency of heat exchange, thereby improving the cooling effect, and further can reduce the equipment energy consumption while meeting the requirements of material cooling.

[0021] The present utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0022] Please refer to the attached Figure 2 , a cooling nozzle of a homogenizer, comprising a main cooling spray pipe 3 of the homogenizer and a cooling diversion branch pipe 4; one end of the main cooling spray pipe 3 of the homogenizer is externally connected to a water supply source, and the other end of the main cooling spray pipe 3 of the homogenizer is closed by a closing plug 301; a plurality of communication holes 302 are formed on the side wall of the main cooling spray pipe 3 of the homogenizer, one ends of a plurality of cooling diversion branch pipes 4 are respectively communicated with the main cooling spray pipe 3 of the homogenizer through the communication holes 302, and the other ends of the plurality of cooling diversion branch pipes 4 extend radially along the main cooling spray pipe 3 of the homogenizer to the spray cooling position of the homogenizer.

[0023] Through the arrangement of the cooling diversion branch pipe 4, it avoids the problem that the nozzles formed by directly opening holes make the spraying direction of the ejected fluid disorderly and irregular, which is conducive to improving the stability of the cooling effect; at the same time, through the arrangement of the cooling diversion branch pipe 4, it has a good diversion effect on the fluid medium, so as to achieve the purpose of constraining the fluid beam, which is conducive to improving the utilization rate of the fluid medium, and further conducive to improving the effect of spray cooling.

[0024] The length of the cooling diversion branch pipe 4 can be adaptively set according to actual use requirements.

[0025] The inner diameter of the main cooling spray pipe 3 of the homogenizer is D, and D is larger than the inner diameter d of the traditional cooling nozzle 1.

[0026] The inner diameter D of the homogenizer cooling spray main pipe 3 of the present utility model is larger than the inner diameter d of the traditional cooling spray pipe 1. The homogenizer cooling spray main pipe 3 can also be made of steel pipe. By expanding the inner diameter of the pipe, when the outlet pressure and flow rate of the output pump of the homogenizer are certain, the flow velocity and outlet pressure of the fluid medium can be reduced, which is beneficial to improving the heat exchange effect and thus improving the cooling effect.

[0027] Please refer to the appendix Figure 2 There are three communication holes 302 provided, and the centers of the three communication holes 302 respectively coincide with the centers of the three nozzles 2 on the traditional cooling spray pipe 1. Three cooling diversion branch pipes 4 are correspondingly connected to the three communication holes 302.

[0028] At the traditional three nozzles 2, three communication holes 302 are concentrically opened and three cooling diversion branch pipes 4 are correspondingly installed, so that the fluid medium directly ejected from the three nozzles 2 is ejected after being diverted by the three cooling diversion branch pipes 4, achieving the purpose of restricting the fluid beam, thereby improving the utilization rate of the fluid medium and further being beneficial to improving the spray cooling effect.

[0029] The lengths of the three cooling diversion branch pipes 4 are the same and are perpendicularly fixedly connected to the homogenizer cooling spray main pipe 3.

[0030] The homogenizer cooling spray main pipe 3 is perpendicular to the three cooling diversion branch pipes 4, that is, the three cooling diversion branch pipes 4 are all arranged along the radial direction of the homogenizer cooling spray main pipe 3 with equal length, ensuring that the restraint effects of the three fluid beams are the same, thereby ensuring a uniform spray cooling effect.

[0031] The diameters of the ends of the three cooling diversion branch pipes 4 far from the homogenizer cooling spray main pipe 3 are D1, D2, and D3 respectively, and D1 is larger than the aperture d1 of the nozzle 2 at its corresponding position, D2 is larger than the aperture d2 of the nozzle 2 at its corresponding position, and D3 is larger than the aperture d3 of the nozzle 2 at its corresponding position.

[0032] The diameters of the three cooling diversion branch pipes 4 are respectively larger than the apertures of the three nozzles 2 at the same position in the traditional one. By expanding the outlet through-diameter of the three fluid beams, when the outlet pressure and flow rate of the output pump of the homogenizer are certain, the flow velocity and outlet pressure of the fluid medium can be reduced, which is beneficial to improving the heat exchange effect and thus improving the cooling effect.

[0033] Please refer to the appendix Figure 2 The working principle of the present utility model is as follows:

[0034] Through the arrangement of the three cooling diversion branch pipes 4, the fluid medium is guided, so that the fluid medium flows out along the three cooling diversion branch pipes 4 to the spray cooling position of the homogenizer, and the flow direction of the fluid beam can be effectively controlled, thereby being able to improve the utilization rate of the fluid medium and further achieving a better spray cooling effect.

[0035] When the outlet pressure and flow rate of the output pump (positive displacement type) of the homogenizer are constant, by providing a homogenizer cooling spray main pipe 3 with a diameter larger than that of the traditional cooling nozzle 1 and a cooling diversion branch pipe 4 with a diameter larger than that of the traditional nozzle 2, the flow velocity and outlet pressure of the fluid medium can be effectively reduced, which is beneficial to further controlling the fluid beam. During the heat exchange process, the utilization rate of the fluid medium can be effectively improved, thereby enhancing the actual cooling effect and meeting the cooling requirements of the material.

[0036] The diameters of the homogenizer cooling spray main pipe 3 and the cooling diversion branch pipe 4 can be determined based on the heat balance equation according to the cooling requirements of the material.

[0037] The above is only a preferred embodiment of the present invention and is not intended to limit the protection scope of the present invention. Therefore, any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
