Description

Technical Field

[0001] The utility model relates to the field of spiral sand washing equipment, in particular to a spiral sand washing device with automatic angle adjustment. Background Art

[0002] Spiral sand washers come in two types: single-spiral and double-spiral. They are primarily used for washing, grading, and removing impurities, as well as for washing fine and coarse materials in industries such as highways, hydropower, and construction. They feature low power consumption and high cleaning efficiency. Their well-sealed structure, fully enclosed transmission, and adjustable weir ensure high efficiency, durability, excellent cleaning and dehydration performance, and a stable fine-grained product.

[0003] At present, the sintering machine head ash becomes a slurry after adding water and stirring in the twin-shaft mixer. It then needs to be passed into the twin-shaft spiral sand washing machine for further processing. The main purpose of processing the sintering machine head ash with the twin-shaft spiral sand washing machine is to clean and separate the soil and impurities in the sand and gravel, and improve the quality of the sand and gravel.

[0004] However, there are differences in the average particle size of particles in different batches of sintering machine head ash, and the inclination angle of the spiral sand washing machine is fixed after it is initially installed, so the inclination angle cannot be automatically adjusted later, and manual adjustment is inconvenient. If the average particle size of the particles in the sintering machine head ash does not match the inclination angle, it will greatly affect the spiral sand washing effect. Utility Model Content

[0005] The purpose of the utility model is to solve the problems raised in the above background technology, and then proposes a spiral sand washing device with automatic angle adjustment.

[0006] The technical solution adopted by the utility model to solve its technical problems is:

[0007] A spiral sand washing device with automatic angle adjustment includes a double-axis spiral sand washing device, a mounting frame, a first hydraulic cylinder, a second hydraulic cylinder, a feed pipe, a detection component and a first solenoid valve.

[0008] The mounting frame is set on the ground;

[0009] The first hydraulic cylinder and the second hydraulic cylinder are both rotatably connected to the mounting frame, and the retractable rods of the first hydraulic cylinder and the second hydraulic cylinder are rotatably connected to the two ends of the double-axis spiral sand washing equipment respectively;

[0010] One end of the discharge pipe is located above the feed end of the twin-shaft spiral sand washing equipment and the other end of the discharge pipe is connected to the discharge port of the twin-shaft stirring equipment;

[0011] The detection component is arranged on the discharge pipe and a first electromagnetic valve is arranged on the discharge pipe.

[0012] Furthermore, the detection element is a visual sensor.

[0013] Furthermore, the double-axis spiral sand washing equipment is movably provided with a cover body, a feed hopper is provided on the cover body, the feed hopper is located below the discharge pipe and a second solenoid valve is provided on the feed hopper.

[0014] Furthermore, a vibration motor is provided on the discharge pipe.

[0015] The above scheme can reduce the probability of other impurities falling into the double-axis spiral sand washing equipment by setting a cover on the double-axis spiral sand washing equipment. At the same time, the sintering machine head ash is added to the double-axis spiral sand washing equipment through the feed hopper. The second solenoid valve has two functions: the first is to temporarily store a small amount of material for easy detection before the visual sensor takes the image, and the second is to close the second solenoid valve when the spiral sand washing process is not in progress to prevent other impurities from entering the double-axis spiral sand washing equipment; finally, the vibration motor can be used to reduce the probability of material accumulation and blockage in the discharge pipe.

[0016] Furthermore, a conveyor belt is provided below the discharge port of the double-axis spiral sand washing equipment and is spaced apart from the discharge port.

[0017] The above solution can transport the materials discharged from the double-axis spiral sand washing equipment to the next area for processing through the conveyor belt, and the conveyor belt does not hinder the double-axis spiral sand washing equipment during the process of adjusting the inclination angle.

[0018] Furthermore, the first hydraulic cylinder and the second hydraulic cylinder are symmetrically arranged on the mounting frame.

[0019] The above solution can effectively improve the support stability of the double-axis spiral sand washing equipment.

[0020] Compared with the prior art, the beneficial effects of the present invention are:

[0021] Compared with the existing technology, this device can automatically detect the average particle size of different batches of sintering machine head ash before spiral sand washing, and then automatically adjust the inclination angle of the double-axis spiral sand washing equipment according to the average particle size of the batch of materials to match the two, thereby making the spiral sand washing process more efficient, and the adjustment process does not require manual intervention.

[0026] 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 work are within the scope of protection of the present invention. The present invention is further described in conjunction with the drawings and embodiments:

[0027] like Figure 1 and Figure 2 As shown, a spiral sand washing device with automatic angle adjustment includes a double-axis spiral sand washing device 1, a mounting frame 2, a first hydraulic cylinder 21, a second hydraulic cylinder 22, a feed pipe 3, a detection member 4 and a first solenoid valve 5.

[0028] The mounting frame 2 is set on the ground;

[0029] The first hydraulic cylinder 21 and the second hydraulic cylinder 22 are both rotatably connected to the mounting frame 2, and the retractable rods of the first hydraulic cylinder 21 and the second hydraulic cylinder 22 are respectively rotatably connected to the two ends of the double-axis spiral sand washing equipment 1 (specifically, the two first hydraulic cylinders 21 and the two second hydraulic cylinders 22 are symmetrically arranged on the mounting frame 2);

[0030] One end of the feed pipe 3 is located above the feed end of the twin-shaft spiral sand washing equipment 1 and the other end of the feed pipe 3 is connected to the discharge port of the twin-shaft stirring equipment;

[0031] The detection component 4 is arranged on the discharge pipe 3 and a first electromagnetic valve 5 is provided on the discharge pipe 3 (specifically, the detection component 4 adopts a visual sensor, and may also adopt a CCD industrial camera).

[0032] In a further refinement of the embodiment of the present invention, a conveyor belt is provided below the discharge port of the double-axis spiral sand washing equipment 1 and is spaced apart from it. The conveyor belt is not shown in the figure and is corrosion-resistant and impact-resistant. The conveyor belt can be used to transport the material discharged from the double-axis spiral sand washing equipment 1 to the next area for processing, and the conveyor belt does not hinder the double-axis spiral sand washing equipment 1 during the adjustment of the inclination angle.

[0033] It should be noted that the first hydraulic cylinder 21 , the second hydraulic cylinder 22 , the detection member 4 and the first solenoid valve 5 are all electrically connected to the controller, which is not shown in the figure.

[0034] The workflow of this utility model:

[0035] First, the controller controls the first solenoid valve 5 to open, and then the sintering machine head ash after stirring is injected into the double-axis spiral sand washing equipment 1 from the discharge pipe 3. After the injection is completed for a predetermined fixed time, the controller controls the first solenoid valve 5 to close. Then, the material can be imaged by the visual sensor. After the image is taken, the result is transmitted to the controller for analysis and calculation to obtain the average particle size of the internal particles. The visual sensor belongs to the prior art and its detection and analysis principle is not described here.

[0036] Then the controller drives the first hydraulic cylinder 21 and the second hydraulic cylinder 22 to move synchronously and in opposite directions according to the average particle size of the particles, that is, when the first hydraulic cylinder 21 contracts, the second hydraulic cylinder 22 extends at an equal distance, and when the first hydraulic cylinder 21 extends, the second hydraulic cylinder 22 contracts at an equal distance, at this time, the inclination angle of the double-axis spiral sand washing equipment 1 can be changed;

[0037] It should be noted that a standard particle size range is set in advance in the controller. If the average particle size of the material detected is larger than the range, the tilt angle of the twin-axis spiral sand washing equipment 1 is increased to the preset value; if the average particle size of the material detected is smaller than the range, the tilt angle of the twin-axis spiral sand washing equipment 1 is reduced to the preset value; then, an efficient spiral sand washing process can be carried out for different batches of sintering machine head ash;

[0038] Compared with the existing technology, this device can automatically detect the average particle size of different batches of sintering machine head ash before spiral sand washing, and then automatically adjust the inclination angle of the double-axis spiral sand washing equipment 1 according to the average particle size of the batch of materials to match the two, thereby making the spiral sand washing process more efficient, and the adjustment process does not require manual intervention.

[0039] In some embodiments, as Figure 2 As shown, a cover body 6 is movably provided on the double-shaft spiral sand washing equipment 1, and a feed hopper 7 is provided on the cover body 6. The feed hopper 7 is located below the discharge pipe 3 and a second solenoid valve 8 is provided on the feed hopper 7;

[0040] In a further optimization of the above embodiment, a vibration motor is provided on the discharge pipe 3, which is not shown in the figure; this embodiment can reduce the probability of other impurities falling into the double-axis spiral sand washing equipment 1 by providing a cover body 6 on the double-axis spiral sand washing equipment 1, and at the same time, the sintering head ash is added to the double-axis spiral sand washing equipment 1 through the feed hopper 7. The second solenoid valve 8 has two functions: the first is that a small amount of material can be temporarily stored for easy detection before the visual sensor takes the image, and the second is that closing the second solenoid valve 8 when the spiral sand washing process is not carried out can prevent other impurities from entering the double-axis spiral sand washing equipment 1; finally, the vibration motor can be used to reduce the probability of material accumulation and blockage in the discharge pipe 3.

[0041] The above shows and describes the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely illustrative of the principles of the present invention. Various changes and improvements may be made to the present invention without departing from the spirit and scope of the present invention. Such changes and improvements are intended to fall within the scope of the present invention.
