Description

Technical Field

[0001] This utility model relates to a leaching device, and more particularly to a flat-rotating leaching device for preventing material blockage, belonging to the field of mechanical equipment technology. Background Technology

[0002] In the production processes of industries such as chemicals and plant extraction, rotary extractors are often used to dissolve and extract materials. However, rotary extractors on the market generally suffer from problems such as material blockage and uneven material discharge. The traditional solution is to stop the machine and have workers use tools at the top of the rotary extractor to break up the accumulated material so that it can fall smoothly. However, this method has certain drawbacks, such as: it is easy to introduce impurities into the rotary extractor, it is easy to cause solvent evaporation and waste, and it is labor-intensive and inefficient.

[0003] To overcome the problems of ordinary rotary leaching machines, technicians have made some improvements to the existing rotary leaching machines. Chinese utility model patent application dated April 15, 1992, and publication number CN2122047U discloses a hydraulic push-out device for a rotary leaching machine. This device is a hydraulic system located on the outer shell of the rotary leaching machine directly above the discharge port. The material is pushed towards the discharge port by the downward movement of the piston. However, this method still has certain drawbacks: regardless of whether there is material accumulation in the material compartment, the piston is always pushing the material downward, and the hydraulic system is always working, resulting in a large amount of resource waste. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a flat rotary leachator that prevents material blockage. When material accumulates in the hopper, the cylinder is activated to squeeze the material downwards, allowing the accumulated material to fall smoothly and avoiding waste of resources. Furthermore, the hopper baffle of this utility model is connected to the outer shell and the rotating shaft by an arc shape, which makes it easier for material to fall compared to the traditional hopper shape.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows: a flat rotary leachator for preventing material blockage, comprising an outer shell with a material grid that can rotate around a rotating shaft inside, a screen connected to the discharge chamber of the discharge mechanism is provided below the material grid inside the outer shell, and a discharge port is opened on the screen corresponding to the position of the discharge mechanism, and an oil storage tank is located below other positions of the screen; a cylinder is provided on the top of the outer shell corresponding to the position of the discharge port to push the material in the material grid toward the discharge port; the discharge mechanism is connected to a control mechanism for controlling the extension and retraction of the cylinder, the control mechanism including a current sensor for detecting the motor current in the discharge mechanism, and the current sensor is connected to a PLC controller for controlling the extension and retraction of the cylinder; the material grid baffle between the two material grids is connected to the outer shell and the rotating shaft in an arc shape, and the shape and size of the discharge port are consistent with the cross-section of the material grid.

[0006] A further improvement of this utility model is that the PLC controller is connected to an air source switch that controls the extension and retraction of the cylinder via a lead wire.

[0007] A further improvement of the present invention is that the rotating shaft vertically penetrates the outer shell and is hinged to the outer shell, and multiple material compartments are evenly arranged circumferentially around the rotating shaft and fixedly connected to the rotating shaft.

[0008] A further improvement of this utility model is that the cylinder is fixed to the top outer wall of the housing by a fixing rod.

[0009] A further improvement of this utility model is that the PLC controller is connected to an alarm device fixed on the side wall of the housing via a lead wire.

[0010] A further improvement of this utility model is that a support leg is installed at the bottom of the outer shell.

[0011] The technological advancements achieved by this utility model due to the adoption of the above technical solution are as follows:

[0012] This invention features a cylinder at the top of the outer casing, corresponding to the discharge port, that pushes the material in the material compartments towards the discharge port. The discharge mechanism is connected to a control mechanism that controls the extension and retraction of the cylinder. The control mechanism includes a current sensor for detecting the motor current in the discharge structure. The current sensor is connected to a PLC controller that controls the extension and retraction of the cylinder. When material accumulates in the material compartments, the current sensor detects that the current inside the motor is less than a set range and transmits a signal to the PLC controller. The PLC controller then controls the cylinder to extend and press the material downwards, allowing the accumulated material to fall smoothly. Furthermore, the material compartment baffle between the two material compartments is connected to the outer casing and the rotating shaft in an arc shape. The shape and size of the discharge port and the cross-section of the material compartments are consistent. This shape of the material compartment and the discharge port makes it easier for material to fall compared to the traditional shape. This invention saves resources while ensuring continuous production.

[0013] The PLC controller of this utility model is also connected to an alarm fixed on the side wall of the outer casing via a lead wire. When material accumulates in the hopper, the current sensor detects that the current inside the motor is less than the set range and transmits a signal to the PLC controller. The PLC controller then activates the alarm and signals the relevant personnel to check the situation inside the horizontal leaching tank, thereby improving the overall safety of the utility model.

[0014] The bottom of the outer shell of this utility model is equipped with support legs, which improves the stability of this utility model in use. Attached Figure Description

[0020] The present invention will be further described in detail below with reference to embodiments:

[0021] like Figure 1 As shown, a non-clogging rotary leaching device has a cylindrical outer shell 14 as its main body. Inside the outer shell 14, there is a ring of material compartments 2 that can rotate around a rotating shaft 15. The rotating shaft 15 vertically penetrates the outer shell 14 and is hinged to two bearings 16 on the upper and lower outer surfaces of the outer shell 14. Multiple material compartments 2 are evenly arranged circumferentially around the rotating shaft 15 and fixedly connected to it. A screen 13 is also provided below the material compartments 2 inside the outer shell 14. The screen 13 has a discharge port, which corresponds to the discharge chamber 5 of the discharge mechanism. Below other locations on the screen 13 is an oil storage chamber 17. A cylinder 4 is located at the top of the outer shell 14, corresponding to the discharge port, to push the material in the material compartments 2 towards the discharge port. The discharge mechanism is connected to a control mechanism that controls the extension and retraction of the cylinder 4. The control mechanism includes a current sensor 7 for detecting the current of the motor 6 in the discharge mechanism, and the current sensor 7 is connected to a PLC controller 8 for controlling the extension and retraction of the cylinder 4. Figure 2 As shown, the baffle 18 between the two material compartments is connected to the outer shell 14 and the rotating shaft 15 in an arc shape, and the shape and size of the discharge port are the same as those of the cross-section of the material compartment 2. This shape of the material compartment 2 and the discharge port makes it easier for material to fall than the traditional shape of the material compartment and the discharge port.

[0022] When material accumulates in the material compartment 2, the current sensor 7 detects that the current inside the motor 6 is less than the set range and transmits a signal to the PLC controller 8. The PLC controller 8 turns on the air source switch 10 and fills the air inlet 19 on the top side wall of the cylinder 4 with gas, controlling the piston 1 of the cylinder 4 to extend and squeeze the material downward, so that the accumulated material can fall smoothly. When the material falls smoothly in the material compartment 2, the current sensor 7 detects that the current inside the motor 6 is within the set range and no longer transmits a signal to the PLC controller 8. The top of the piston 1 of the cylinder 4 is metal, and it contracts under the attraction of the magnet 11 on the top of the inner wall of the cylinder 4. This utility model saves resources while ensuring continuous production.

[0023] In one embodiment of the present invention, the cylinder 4 is fixed to the top outer wall of the housing 14 by a fixing rod 3.

[0024] In another embodiment of this utility model, the PLC controller 8 is connected to an alarm 9 fixed on the side wall of the housing 14 via a lead wire. When material accumulates in the material compartment 2, the current sensor 7 detects that the current inside the motor 6 is less than the set range and transmits a signal to the PLC controller 8. The PLC controller 8 then activates the alarm 9 to sound an alarm, indicating to the relevant personnel to check the situation inside the horizontal leaching tank, thereby improving the overall safety of the utility model.

[0025] In another embodiment of this utility model, a support leg 12 is installed at the bottom of the outer shell 14, which improves the stability of the utility model during use.
