Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of flotation machines, and particularly relates to a screen assembly for a flotation machine. BACKGROUND BACKGROUND

[0003] In the application of the flotation machine, the screen assembly plays a crucial role, and its performance directly affects the flotation efficiency and product quality. However, the traditional screen assembly design has obvious shortcomings, mainly in the following two aspects: 1. The traditional screen assembly often only uses the middle part of the screen plate for material screening, while the edge part of the screen plate is idle, which not only limits the effective working area of the screen plate, but also leads to the reduction of the overall screening efficiency, affecting the overall efficiency of the production line. 2. The screen plate material is seriously wasted: when the middle part of the screen plate is damaged due to long-term use or wear, the entire screen plate needs to be replaced according to the traditional method. However, in actual situations, the edge part of the screen plate often remains in good condition and has value for continued use. This "one-size-fits-all" replacement method not only increases production costs, but also causes serious waste of screen plate materials.

[0004] In order to improve the utilization rate of the screen plate and reduce the waste of the screen plate material, it is necessary to improve the existing screen assembly design. CONTENT OF THE INVENTION

[0005] The purpose of the present application is to provide a screen assembly for a flotation machine that can solve the above problems.

[0006] The purpose of the present application is to provide a screen assembly for a flotation machine, comprising:

[0007] The screen plate is used for separating impurities.

[0008] The support is arranged on both sides of the screen plate and is used for fixing the screen plate.

[0009] The connecting piece has one end connected with the support and the other end extending upward and connected with the fluid outlet.

[0010] The connecting piece has one end connected with the support and the other end extending upward and connected with the fluid outlet.

[0011] The screen plate is fixed by the cooperation of the connecting piece and the support, the fluid enters through the connecting piece and flows out through the screen plate, and the separation of impurities is completed.

[0012] The above-mentioned optimization screen assembly for the flotation machine, the screen plate as the core component of separating impurities is made of high-efficiency screening material, and has excellent wear resistance and corrosion resistance. The support is arranged on both sides of the screen plate, which can effectively withstand the impact of the fluid and the weight of the screen plate. One end of the connecting piece is firmly connected with the support, and the other end extends upward and is connected with the fluid outlet, which not only ensures the stability of the screen plate, but also enables the fluid to flow smoothly out of the screen plate, avoiding the accumulation and blockage of the fluid on the screen plate. The connecting pipe is arranged on the support and is connected with the inside of the screen plate, so that the fluid can enter the screen plate uniformly and stably, thereby improving the screening effect and efficiency.

[0013] By reducing the size of the screen plate, the area of the screen plate is maximized, the waste of materials is reduced, and the screening efficiency is improved, so that more impurities can be effectively separated. Through the clever cooperation of the support and the connecting piece, the screen plate can maintain stability under the impact of the fluid, avoiding the risk of falling off or damage, which not only improves the durability of the screen assembly, but also reduces the maintenance cost. The support is also convenient for installation and disassembly, so that when the screen plate needs to be replaced or repaired, it can be easily operated.

[0014] Further, the support comprises:

[0015] The support plate is arranged at the bottom of the screen plate, and a first through hole for the fluid to pass through is formed on the surface of the support plate;

[0016] The pressing plate is arranged at the top of the support plate, and a second through hole for the fluid to pass through is formed on the surface of the pressing plate;

[0017] The pressing plate is welded with the connecting pipe, and the connecting pipe is in communication with the second through hole.

[0018] The support plate is arranged at the bottom of the screen plate, and a first through hole for the fluid to pass through is formed on the surface of the support plate;

[0019] Further, the connecting piece comprises:

[0020] Screws, provided with multiple;

[0021] Nuts, used to fix the screws;

[0022] Among them, the nuts are arranged on the lower part of the support plate and the upper part of the pressing plate, and through the cooperation of the screws and the nuts, the pressing plate and the support plate are fixed on both sides of the screen plate.

[0023] The screws, as the main component of the connecting piece, are provided with multiple to ensure that the support plate and the pressing plate can be uniformly and firmly fixed on both sides of the screen plate, and the position distribution of the screws needs to consider the position of other components to avoid interference. The nuts are used to fix the screws, and through the thread cooperation with the screws, the support plate and the pressing plate are tightly fixed on both sides of the screen plate. The nuts are arranged on the lower part of the support plate and the upper part of the pressing plate, which not only enhances the stability of the screen plate, but also ensures that the fluid will not leak due to the shaking of the screen plate during the screening process. At the same time, by adjusting the fastening degree of the nuts, the control of the fixing force of the screen plate can be realized, so as to ensure the stability and durability of the screen assembly during the screening process. Through the ingenious cooperation of the screws and the nuts, the firm fixation and stable installation of the screen plate are realized, which not only improves the screening efficiency, but also ensures the durability and reliability of the screen assembly.

[0024] Further, flat washers are arranged between the support plate and the nut, and between the pressing plate and the nut.

[0025] The flat washers are arranged between the support plate and the nut, and between the pressing plate and the nut, which are used to increase the contact area between the nut and the support plate or the pressing plate, so as to disperse the pressure generated by the nut and prevent the connecting parts from being damaged due to excessive pressure. The flat washers can also provide additional friction to help prevent the nut from loosening under vibration or external force.

[0026] Further, spring washers are arranged between the nut and the flat washer.

[0027] The spring washers are arranged between the nut and the flat washer, which are used to provide additional elastic pre-tightening force to compensate for the loosening of the nut due to vibration, temperature change or long-term load. When the nut is subjected to external force, the spring washer will be elastically deformed, thereby absorbing part of the impact force and protecting the connecting parts from being damaged.

[0028] The beneficial effects of the present application are:

[0029] 1. By reducing the size of the screen plate, the area of the screen plate is maximized, the waste of materials is reduced, and the screening efficiency is improved, so that more impurities can be effectively separated;

[0030] 2、Through the ingenious cooperation of the support and the connecting piece, the screen plate can be kept stable under fluid impact, avoiding the risk of falling off or damage, not only improving the durability of the screen assembly, but also reducing the maintenance cost;

[0031] 3、By setting the spring washer between the nut and the flat washer, additional elastic pre-tightening force can be provided to compensate for nut loosening caused by vibration, temperature changes or long-term load. BRIEF DESCRIPTION OF DRAWINGS
