[0030] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0031] Reference Figure 1-Figure 3The utility model provides an embodiment: an MVR concentrating evaporator for copper electrolyte purification, comprising a shell 1, which is the main body of the MVR concentrating evaporator for copper electrolyte purification, which is a prior art. The front end outer wall of the shell 1 is fixedly connected with a discharge port 5, and the concentrated and evaporated copper electrolyte can be discharged through the discharge port 5. The bottom outer wall of the shell 1 is fixedly connected with a slider 6, and the bottom outer wall of the slider 6 is provided with a buffer mechanism 3. When the shell 1 vibrates and generates noise during operation, the slider 6 and the buffer mechanism 3 can play a buffering effect to prevent the shell 1 from being damaged due to excessive vibration amplitude and reduce the noise generated by the vibration. The top outer wall of the shell 1 is provided with a mounting mechanism 2, and the top of the shell 1 is detachably mounted with a connecting pipe 4 through the mounting mechanism 2. The connecting pipe 4 is a copper electrolyte delivery pipe. The connecting pipe 4 can be conveniently and quickly disassembled and installed through the mounting mechanism 2, so that it can be cleaned or replaced.

[0032] Reference Figure 2 The mounting mechanism 2 includes a mounting base 201, which is fixedly connected to the top outer wall of the shell 1. The connecting pipe 4 can be fixed through the mounting base 201. The inner wall of the mounting base 201 is slidably connected with a trapezoidal block 202. The front end long side of the trapezoidal block 202 passes through the front end outer wall of the mounting base 201, so that the trapezoidal block 202 can be pressed. The inner wall of the mounting base 201 is slidably connected with a connecting rod 203. Two groups of connecting rods 203 are provided and are symmetrically distributed on the inner walls on both sides of the mounting base 201.

[0033] Reference Figure 2 One end of the connecting rod 203 is fixedly connected to the outer wall of the wedge block 205, and the other end of the connecting rod 203 is slidably connected to the outer wall of the trapezoidal block 202. When not affected by external force, the connecting rod 203 contacts the short side wall of the trapezoidal block 202. When the trapezoidal block 202 is pressed, the two sets of connecting rods 203 can be moved to the long side of the trapezoidal block 202, thereby moving to both sides. The inner wall of the mounting seat 201 is elastically connected to the wedge block 205 through the return spring 204. The wedge block 205 maintains the arc surface facing upward to facilitate the installation of the connecting pipe 4. Two sets of wedge blocks 205 and return springs 204 are provided.

[0034] Reference Figure 2 One end of the return spring 204 is fixedly connected to the outer wall of the wedge block 205, and the other end of the return spring 204 is fixedly connected to the inner wall of the mounting seat 201. When the connecting pipe 4 is installed, the arc surface of the wedge block 205 is squeezed, so that the wedge block 205 moves inward along the inner wall of the mounting seat 201. The return spring 204 is forced to shrink, and the outer wall of the wedge block 205 is slidably connected to the inner wall of the mounting seat 201. When the connecting pipe 4 is installed to the slot 207 corresponding to the position of the wedge block 205, the return spring 204 drives the wedge block 205 to pop out outward due to the elastic force and engages with the slot 207, thereby fixing the connecting pipe 4.

[0035] Reference Figure 2 The outer wall of the bottom end of the connecting pipe 4 is fixedly connected with a fixing block 206, and a card slot 207 is opened on the outer wall of the fixing block 206. The wedge block 205 is engaged with the card slot 207. By pressing the trapezoidal block 202 to make the connecting rod 203 drive the wedge block 205 to move outward, the limit of the fixing block 206 can be released, so that the connecting pipe 4 can be removed quickly and conveniently. The outer wall of the bottom end of the fixing block 206 is fixedly connected with a rubber pad 208. When the connecting pipe 4 is installed, the rubber pad 208 is deformed by the squeezing force of the fixing block 206 and the mounting seat 201, so that the two fit more closely, thereby improving the sealing effect.

[0036] Reference Figure 3 The buffer mechanism 3 includes a base 301, which can be placed on the ground to support the shell 1. The base 301 is slidably connected to the outer wall of the slider 6. When the shell 1 vibrates, the slider 6 moves up and down in the inner wall of the base 301. The base 301 is elastically connected to the bottom outer wall of the slider 6 through an elastic telescopic rod 302. The elastic telescopic rod 302 is provided with multiple groups, the bottom end of which is connected to the bottom inner wall of the base 301, and the movable end is fixedly connected to the bottom outer wall of the slider 6, which can support the shell 1 and have a certain buffering effect.

[0037] Reference Figure 3 The inner wall of the base 301 is rotatably connected to a rotating wheel 303. Two groups of rotating wheels 303 are symmetrically distributed on the inner walls on both sides of the base 301. A traction rope 304 is wound around the outer wall of the rotating wheel 303. The rotating wheel 303 can change the pulling direction of the traction rope 304. One end of the traction rope 304 is fixedly connected to the outer wall of the slider 6, and the other end of the traction rope 304 is fixedly connected to the top outer wall of the counterweight block 307. When the slider 6 moves downward due to vibration, the traction rope 304 is pulled and the counterweight block 307 can be driven to move upward under the action of the rotating wheel 303. Since the counterweight block 307 has a heavier gravity itself, the amplitude of the up and down movement of the slider 6 can be reduced.

[0038] Reference Figure 3 The inner wall of the bottom end of the base 301 is elastically connected to the counterweight block 307 through a buffer spring 308. When the counterweight block 307 moves upward, the buffer spring 308 is stretched. One end of the buffer spring 308 is fixedly connected to the outer wall of the bottom end of the counterweight block 307, and the other end of the buffer spring 308 is fixedly connected to the inner wall of the bottom end of the base 301. The outer wall of the counterweight block 307 contacts the inner wall of the base 301. When the slider 6 moves up and down due to vibration, the counterweight block 307 moves upward under tension, and can move downward and reset through the elastic force of the buffer spring 308.

[0039] Reference Figure 3The outer wall of the counterweight block 307 is fixedly connected to a rubber ring 306, and a groove 305 is opened on the inner wall of the base 301. The rubber ring 306 contacts the inner wall of the groove 305. When the counterweight block 307 moves, the rubber ring 306 continuously contacts the inner wall of the groove 305, thereby increasing the friction force, making the movement resistance of the counterweight block 307 greater, thereby improving the buffering effect.

[0040] Working principle: When in use, the fixing block 206 below the connecting pipe 4 can be aligned with the opening position above the mounting seat 201 and moved downward to squeeze the arc surface of the wedge block 205, so that the wedge block 205 moves inward along the inner wall of the mounting seat 201. When the fixing block 206 moves to the position corresponding to the slot 207 and the wedge block 205, the return spring 204 drives the wedge block 205 to pop out due to the elastic force, and the straight surface of the wedge block 205 contacts the inner wall of the slot 207, which can limit the connecting pipe 4 and prevent the connecting pipe 4 from falling off, thereby completing the installation of the connecting pipe 4.

[0041] Then the copper electrolyte can be input into the shell 1 from the connecting pipe 4, and the concentration and evaporation operation can be carried out through the shell 1. The evaporated copper electrolyte can be discharged through the discharge port 5. Vibration and noise will be generated during the operation of the shell 1. When the shell 1 vibrates, the slider 6 moves downward in the inner wall of the base 301, the elastic telescopic rod 302 is forced to shrink, and the traction rope 304 drives the counterweight block 307 to move upward under the rotation of the rotating wheel 303. The buffer spring 308 is forced to stretch, and the rubber ring 306 continuously contacts the inner wall of the groove 305, increasing the friction of the counterweight block 307, thereby increasing the resistance of the counterweight block 307, which can reduce the downward movement of the slider 6. Then the buffer spring 308 drives the counterweight block 307 to move downward and reset due to the elastic force. The movable end of the elastic telescopic rod 302 pops up due to the elastic force, which can have a good buffering effect on the slider 6 and the shell 1, reducing the damage that the vibration may cause to the shell 1 and the connecting pipe 4, and reducing noise pollution to a certain extent.

[0042] When the inner wall of the connecting tube 4 needs to be cleaned or replaced after a long period of use, the trapezoidal block 202 can be pressed inward to squeeze the connecting rod 203, so that the two sets of connecting rods 203 drive the corresponding wedge blocks 205 to move outward and disengage from the slots 207, thereby releasing the limit of the connecting tube 4 and allowing the connecting tube 4 to be taken out quickly and conveniently. There is no need to disassemble and install the connecting tube 4 by turning the bolts multiple times, which saves time and effort.

[0043] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
