Description

Technical Field

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

[0002] The working process of the existing homogenizer plunger: After the homogenizer is started, the plunger is driven to reciprocate through a belt, gears, a crankshaft and a connecting rod. When the plunger moves backward and the tight fit between the plunger and the plunger seal forms a vacuum, the lower one-way valve is opened, the upper one-way valve is closed, and the plunger sucks materials. When the plunger moves forward, the lower one-way valve is closed, the upper one-way valve is opened, and the plunger feeds materials. Then it comes to the material conveying and processing process of homogenization and discharging. In this process, whether the plunger and the plunger seal fit tightly is the key to stable and sufficient material suction of the plunger.

[0003] The existing homogenizer plunger 3 is made of a solid metal rod, as shown in the attached Figure 1 figure. Its disadvantage is that the mass of the homogenizer plunger is relatively large. For some high-flow homogenizers, a large-diameter homogenizer plunger is often required, resulting in an increase in the sagging force of the homogenizer plunger due to its own weight. The pressure of the bottom of the homogenizer plunger on the plunger seal increases accordingly, which easily causes accelerated wear of the bottom of the homogenizer plunger on the plunger seal, and further leads to a significant reduction in the service life of the homogenizer plunger seal. Therefore, it is necessary to provide a homogenizer plunger that can solve the problem of the large self-weight of the homogenizer plunger in the prior art and the easy acceleration of the wear speed of the plunger seal. Summary of the Invention

[0004] The purpose of the utility model is to provide a homogenizer plunger that can solve the problem of the large self-weight of the homogenizer plunger in the prior art and the easy acceleration of the wear speed of the plunger seal.

[0005] The utility model is realized as follows:

[0006] A homogenizer plunger includes a plunger cylinder body and a plunger chuck; a hollow chamber is formed in the plunger cylinder body, and the hollow chamber penetrates one end of the plunger cylinder body, so that the plunger cylinder body forms a hollow cylindrical structure with one end open and the other end closed; one end of the plunger chuck is fixedly connected to the open end of the plunger cylinder body to form the homogenizer plunger.

[0007] Internal threads are formed on the inner wall of the open end of the plunger cylinder body, and external threads are formed at one end of the plunger chuck, which are matched with the internal threads, so that one end of the plunger chuck is screwed onto the open end of the plunger cylinder body.

[0008] A flange is formed at one end of the plunger chuck, and the outer diameter of the flange is the same as the outer diameter of the plunger cylinder body, so that after the plunger chuck is screwed onto the plunger cylinder body, the outer wall of the flange and the outer wall of the plunger cylinder body are located on the same cylindrical wall.

[0009] One end of the described plunger chuck is fixedly connected to the open end of the plunger cylinder body through welding material.

[0010] The described plunger cylinder body, hollow chamber, plunger chuck and flange are coaxially arranged.

[0011] Compared with the prior art, the present utility model has the following beneficial effects:

[0012] 1. Since the present utility model is provided with a plunger cylinder body with a hollow chamber, compared with the homogenizer plunger made of solid bar stock in the prior art, the hollow-form homogenizer plunger of the present utility model has a smaller self-weight, thus reducing the pressure of the bottom of the homogenizer plunger on the plunger seal, delaying the wear rate of the bottom of the homogenizer plunger on the plunger seal, and further extending the service life of the plunger seal.

[0013] 2. Since the present utility model is provided with a plunger cylinder body and a plunger chuck, and the homogenizer plunger is made of a split structure, it is convenient for processing the hollow chamber inside the plunger cylinder body. The integral property of the homogenizer plunger and the movement synchronization of the plunger cylinder body and the plunger chuck are ensured by means of threaded connection and welding reinforcement, so as to achieve the same quality and use effect as the homogenizer plunger in the prior art. Description of the Drawings

[0014] Figure 1 is the front view of the homogenizer plunger in the prior art;

[0015] Figure 2 is the cross-sectional view of the homogenizer plunger of the present utility model.

[0016] In the figure, 1 is the plunger cylinder body, 101 is the hollow chamber, 2 is the plunger chuck, 201 is the flange, and 3 is the homogenizer plunger (prior art). Detailed Embodiments

[0017] The present utility model will be further described below in conjunction with the drawings and specific embodiments.

[0018] Please refer to the attached Figure 2 , a homogenizer plunger, comprising a plunger cylinder body 1 and a plunger chuck 2; a hollow chamber 101 is formed inside the plunger cylinder body 1, and the hollow chamber 101 penetrates one end of the plunger cylinder body 1, so that the plunger cylinder body 1 forms a hollow cylindrical structure with one end open and the other end closed; one end of the plunger chuck 2 is fixedly connected to the open end of the plunger cylinder body 1 to form a homogenizer plunger.

[0019] By providing the hollow chamber 101, the self-weight of the homogenizer plunger can be significantly reduced, thus avoiding the problem that the large-diameter homogenizer plunger accelerates the wear of the plunger seal due to its large self-weight, and the service life of the plunger seal can be extended. The size of the hollow chamber 101 can be adaptively set according to the diameter, weight of the homogenizer plunger, the pressure on the plunger seal and the wear condition, and it is necessary to ensure that the homogenizer plunger has sufficient strength to avoid bending deformation or even fracture during use.

[0020] To facilitate the provision of the hollow chamber 101, a split structure of the plunger cylinder 1 and the plunger chuck 2 is adopted. After the hollow chamber 101 is formed, the open end of the plunger cylinder 1 is closed by the plunger chuck 2, which also facilitates the installation of the plunger cylinder 1 on the homogenizer through the plunger chuck 2.

[0021] Internal threads are formed on the inner wall of the open end of the plunger cylinder 1, and external threads matching the internal threads are formed at one end of the plunger chuck 2, so that one end of the plunger chuck 2 is screwed onto the open end of the plunger cylinder 1.

[0022] The reliable connection and integrity between the plunger cylinder 1 and the plunger chuck 2 are ensured by the screw connection, which is convenient for assembly, forming an integral homogenizer plunger, and also facilitating the assembly connection between the homogenizer plunger and the homogenizer.

[0023] A flange 201 is formed at one end of the plunger chuck 2, and the outer diameter of the flange 201 is the same as the outer diameter of the plunger cylinder 1, so that after the plunger chuck 2 is screwed onto the plunger cylinder 1, the outer wall of the flange 201 and the outer wall of the plunger cylinder 1 are on the same cylindrical wall.

[0024] By providing the flange 201, it is beneficial to improve the screwing stability between the plunger chuck 2 and the plunger cylinder 1, and also convenient for subsequent welding reinforcement. At the same time, by using the abutting limit between the flange 201 and the end of the plunger cylinder 1, it is beneficial to improve the assembly accuracy between the plunger chuck 2 and the plunger cylinder 1.

[0025] One end of the plunger chuck 2 and the open end of the plunger cylinder 1 are fixedly connected by welding material to reinforce the connection strength between the plunger chuck 2 and the plunger cylinder 1, prevent the relative movement between the plunger chuck 2 and the plunger cylinder 1, and ensure the integrity of the entire homogenizer plunger and the movement synchronization between the plunger chuck 2 and the plunger cylinder 1.

[0026] The plunger cylinder 1, the hollow chamber 101, the plunger chuck 2 and the flange 201 are coaxially arranged to ensure the uniform force on each part of the homogenizer plunger during movement, thereby ensuring the movement stability of the homogenizer plunger.

[0027] Please refer to the appendix Figure 2 , the processing method of the present utility model is:

[0028] The plunger cylinder body 1 and the plunger chuck 2 are made of the materials of the homogenizer plunger in the prior art, and the plunger cylinder body 1 and the plunger chuck 2 are made according to the dimensions of the homogenizer plunger in the prior art. A hollow chamber 101 is reserved in the plunger cylinder body 1 to reduce the weight of the plunger cylinder body 1 while ensuring that the plunger cylinder body 1 has sufficient strength and will not be deformed or damaged.

[0029] A section of internal thread is machined on the inner wall of the open end of the plunger cylinder body 1, and a section of external thread is machined at one end of the plunger chuck 2. Through the mutual matching and screwing of the internal and external threads, it is convenient for the positioning and assembly of the plunger chuck 2 on the plunger cylinder body 1. The connection between one end of the plunger chuck 2 and the open end of the plunger cylinder body 1 is welded and reinforced to avoid relative rotation and movement between the plunger chuck 2 and the plunger cylinder body 1.

[0030] After the plunger chuck 2 and the plunger cylinder body 1 are assembled, they form a homogenizer plunger. The weight of the homogenizer plunger of the present invention is about 30% lighter than that of the traditional homogenizer plunger. The installation and use methods of the homogenizer plunger of the present invention in the homogenizer are the same as those in the prior art and will not be elaborated here.

[0031] The above are only the preferred embodiments of the present invention and are not used 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 in the protection scope of the present invention.
