Description

[0002] The high frequency screen of automatic amplitude adjustment can automatically adjust the amplitude according to the amount of material, thereby ensuring that the material maintains a stable motion state on the screen surface.

[0026] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this utility model.

[0027] Example 1

[0028] like Figures 1-6 As shown, this embodiment proposes a high-frequency screen with automatic amplitude adjustment, including a support base 1, two angle adjustment mechanisms 2 installed on the top of the support base 1, a screen box 3 installed on the top of the two angle adjustment mechanisms 2, an excitation mechanism 4 installed on the left side of the screen box 3, a vibration mechanism 5 installed in front of the excitation mechanism 4 and located on the left side of the screen box 3, a water spray pipe 6 connected to the inside of the screen box 3, a water storage tank 7 fixedly connected to the right side of the support base 1, a pumping mechanism 8 installed on the right side of the water storage tank 7, an anti-blocking mechanism 9 installed on the outside of the water storage tank 7, a swing mechanism 10 installed on the top of the screen box 3, and rubber springs 11 installed around the bottom of the support base 1.

[0029] The anti-blocking mechanism 9 comprises two connecting pipes 91, a fixing box 92 and two storage boxes 911. The left side of the connecting pipe 91 is fixedly connected to the right side of the water storage box 7. The rear side of the fixing box 92 is fixedly connected to the front side of the water storage box 7. The right side of the storage box 911 is fixedly connected to the left side of the water storage box 7. The proximal end of the two connecting pipes 91 is fixedly connected with a mounting shell 93. The inner top wall of the mounting shell 93 is mounted with a positive electrode 94 of a power supply. The inner bottom wall of the mounting shell 93 is mounted with a negative electrode 95 of the power supply. A guide rod 96 is mounted between the positive electrode 94 and the negative electrode 95 of the power supply. The outer side of the guide rod 96 is slidingly connected with a conductive sheet 97. The right side inner wall of the fixing box 92 is fixedly connected with a motor 98. The output end of the motor 98 is fixedly connected with a gear 99. The upper and lower sides of the gear 99 are both meshingly connected with a rack 910. The bottom of the storage box 911 is fixedly connected with a fixing pipe 912. The end, away from the storage box 911, of the fixing pipe 912 is fixedly connected to the left side of the water storage box 7.

[0030] The pumping mechanism 8 comprises a water pump 81. The left side of the water pump 81 is fixedly connected to the right side of the water storage box 7. The input end of the water pump 81 is fixedly connected with a water pumping pipe 82. The end, away from the water pump 81, of the water pumping pipe 82 is fixedly connected to the outer side of the water storage box 7. The output end of the water pump 81 is fixedly connected with a conveying pipe 83. The end, away from the water pump 81, of the conveying pipe 83 is fixedly connected to the outer side of the fixing block 102.

[0031] The purpose of such a setting is that, in use, the material is poured from the feed bin to the discharge port and falls on the screening box, and the pressure sensor arranged at the bottom of the screening box monitors the amount of material in real time. When the amount of material increases, the pressure sensor detects the corresponding pressure change and transmits the data to the controller, which adjusts the amplitude of the vibration mechanism 4 according to the received data to adapt to the change in the amount of material. The water pump 81 is started to drive the water suction pipe 82 to suck the water in the water storage tank 7 and send it to the inside of the fixed block 102 through the delivery pipe 83. Since the fixed block 102 and the water inlet pipe 103 are connected, water flows into the water inlet pipe 103, and then flows to the water spray pipe 6 through the connecting pipe 104. The water is sprayed through the nozzles on the water spray pipe, and the swing mechanism 10 is started to drive the water spray pipe 6 to swing, expanding the spraying range. The combination of the water storage tank 7, the connecting pipe 91 and the mounting shell 93 forms a communicating vessel. Since the connecting pipe 91 and the water storage tank 7 are connected, the internal pH value changes, and the internal pH value of the external mounting shell 93 also changes. When the alkalinity of the sprayed water is greater, the buoyancy of the water is higher (at this time, the water in the water storage tank 7 is full, the pH value of the water is normal, the conductive sheet 97 is in the middle of the guide rod 96, the top storage tank 911 contains alkaline solution, and the bottom is acidic solution). At this time, the conductive sheet 97 will float up and abut against the positive electrode 94 of the power supply. Since the top of the conductive sheet 97 is negative, a closed circuit is formed, and the current flows from the positive electrode to the negative electrode, driving the motor 1 98 to rotate in the positive direction. The motor 1 98 rotates in the positive direction to drive the bottom rack 910 to move outward, thereby opening the bottom storage tank 911 to send the acidic solution to the inside of the water storage tank 7 through the fixed pipe 912, and mixing it more uniformly with the stirring mechanism arranged inside the water storage tank 7. When the pH value starts to recover, the conductive sheet 97 does not contact the positive electrode 94 of the power supply, and the starting is stopped. When the acidity of the water in the water storage tank 7 is higher, the buoyancy of the water will be smaller, that is, the motor 1 98 will work in the opposite direction.

[0032] Preferably, the rack 910 is slidably connected with the water storage tank 7 and the fixed tank 92, respectively. The purpose of such a setting is to enable the rack 910 to slide stably.

[0033] Preferably, the positive electrode 94 and the negative electrode 95 of the power supply are electrically connected with the motor 1 98 through power lines. The purpose of such a setting is to enable the positive and negative electrodes of the power supply and the conductive sheet 97 to abut against each other to start the motor 1 98.

[0034] Preferably, the top of the conductive sheet 97 is negative and the bottom is negative. The purpose of such a setting is to enable a closed circuit to be formed.

[0035] Preferably, the water storage tank 7 is connected with the connecting pipe 91 and the mounting shell 93. The purpose of such a setting is that the three are matched to form a communicating vessel.

[0038] The purpose of such a setting is that, in use, the rotating shaft 106 and the bent rod 107 are driven to rotate by the motor two 105, and then the bent rod 107 is rotated outside the U-shaped plate, and its movement is transmitted to the U-shaped plate to drive the U-shaped plate to rotate outside the mounting block 109, and then drive the mounting block 109 and the water inlet pipe 103 to rotate, so as to drive the water spraying pipe 6 to swing back and forth through the connecting pipes 104, thereby expanding the spraying range.

[0039] Preferably, the conveying pipe 83 is connected in communication between the fixed block 102 and the water inlet pipe 103, and the purpose of such a setting is to make the water source be conveyed into the water inlet pipe 103.
