Description

[0002] Screening machine is a commonly used equipment in industrial production, which is used to screen materials and separate light materials and other impurities from heavy materials and aggregates.

[0033] Example 1

[0034] This embodiment provides a high-pressure air supply and sorting integrated sieve plate device, which uses the set sieve plates to control material screening in different areas, so that the materials in each area on the sieve plate are more reasonably exposed to the wind, thereby improving the screening efficiency.

[0035] like Figure 1 and Figure 2 As shown, the high-pressure air supply and sorting integrated sieve plate device includes multiple air chamber units, a connecting component, an air intake component 2 and an air pressure regulating mechanism 21, and the air intake component 2 is connected to the multiple air chamber units through the connecting component. Driven by the air intake component 2, the multiple air chamber units are blown through the connecting component. The air chamber unit is provided with a sieve hole 123, and the airflow in the air chamber unit is ejected through the sieve hole 123 to screen the materials placed on the air chamber unit. Among them, under the action of the airflow, the light material is separated from the heavy material, thereby achieving the effect of separation and screening. In the process of separation and screening, the light material moves along the ejection direction of the airflow, and the heavy material stays in place first. Multiple air chamber units are connected to the vibration disk 2, and the vibration disk 2 is connected to the vibration component (not shown in the figure). Under the vibration of the vibration component, the vibration disk 2 continues to vibrate, and the vibration disk 2 drives the air chamber unit to vibrate, so that the heavy material staying on the air chamber unit moves in the opposite direction to the light material, thereby achieving further screening and separation of the heavy material and the light material.

[0036] The air intake assembly 2 may include one or more high-pressure air compressors 25. The air intake assembly 2 of this embodiment includes a high-pressure air compressor 25, and the connecting assembly may include a main air intake pipe 22 and multiple branch air pipes 23. The two ends of the multiple branch air pipes 23 are respectively connected to one end of the main air intake pipe 22 and the corresponding multiple air chamber units, and the other end of the main air intake pipe 22 is connected to the high-pressure air compressor 25, so that the high-pressure air compressor 25 is connected to the multiple air chamber units. The high-pressure air compressor 25 blows air to the air chamber unit, and the air chamber unit blows air to the material through the set sieve holes 123 to separate and screen the material. An air pressure regulating mechanism 21 is set on each branch air pipe 23, and the air pressure regulating mechanism 21 is controlled to adjust the air intake pressure and air intake volume of each air chamber unit.

[0037] In some feasible embodiments, one end of each branch air pipe 23 away from the main air intake pipe 22 can also be connected to one end of multiple sub-bronchial pipes 24, and the other ends of the multiple sub-bronchial pipes 24 are respectively connected to the air cavity units. An air pressure regulating mechanism 21 can be installed on each sub-bronchial pipe 24, so that the air intake pressure and air intake volume of the corresponding multiple sub-bronchial pipes 24 can be adjusted simultaneously by controlling the air pressure regulating mechanism 21 on the branch air pipe 23, and the air intake pressure and air intake volume of the corresponding air cavity unit can also be adjusted separately by controlling the air pressure regulating mechanism 21 on each sub-bronchial pipe 24.

[0038] Example 2

[0039] The air intake assembly 2 of this embodiment includes a plurality of high-pressure air compressors 25, and the connection assembly may include a plurality of directly connected air pipes corresponding to the number of high-pressure air compressors 25, each high-pressure air compressor 25 is correspondingly connected to one end of each directly connected air pipe, and the other end of each directly connected air pipe is connected to the air cavity unit. Each air cavity unit is provided with a blasting power by a separate high-pressure air compressor 25, so that the blasting of the air cavity unit is larger, and a larger amount of materials can be blasted and screened. An air pressure regulating mechanism 21 may also be installed on each directly connected air pipe to control the air pressure regulating mechanism 21 and adjust the air intake pressure and air intake volume of the air cavity unit corresponding to the directly connected air pipe.

[0040] Each wind chamber unit can include one wind chamber or multiple wind chambers; this can be selected according to the volume of the material to be processed. When the volume of the material is small, one wind chamber unit can be selected to correspond to one wind chamber; when the volume of the material is large, one wind chamber unit can be selected to correspond to multiple wind chambers. In addition, the number of wind chambers corresponding to one wind chamber unit can be determined according to the fineness of the material to be screened. For materials with higher screening accuracy requirements, one wind chamber unit can be selected to correspond to one wind chamber; for materials with lower screening accuracy requirements, one wind chamber unit can be selected to correspond to multiple wind chambers.

[0041] Example 3

[0042] In this embodiment, one air chamber unit corresponds to one air chamber, and the air intake assembly 2 may include a high-pressure air compressor 25, and the connecting assembly may include a main air intake pipe 22 and multiple branch air pipes 23. One end of the main air intake pipe 22 is connected to the high-pressure air compressor 25, and the other end is connected to one end of multiple branch air pipes 23, and the other end of the multiple branch air pipes 23 is connected to the corresponding multiple air chambers. The high-pressure air compressor 25 is connected to the ventilation chamber through the main air intake pipe 22 and the branch air pipes 23 in turn, and blows air into the air chamber to form an airflow in the air chamber. The air chamber is provided with a sieve hole 123, and the airflow is blown out through the sieve hole 123 to perform air blowing and screening on the material. An air pressure regulating mechanism 21 corresponding to the air chamber can be provided on each branch air pipe 23, and the air pressure regulating mechanism 21 is controlled to adjust the air intake pressure and air intake volume of the corresponding air chamber.

[0043] In some feasible embodiments, the air intake assembly 2 may include multiple high-pressure air compressors 25, and the multiple high-pressure air compressors 25 may be simultaneously connected to a main air intake pipe 22, and the main air intake pipe 22 may be correspondingly connected to multiple air chambers through multiple branch air pipes 23. Under the simultaneous action of the multiple high-pressure air compressors 25, the air intake pressure and air intake volume of the air chamber are relatively large, which can be used in situations where there are more and heavier materials.

[0044] Example 4

[0045] One air chamber unit of this embodiment corresponds to multiple air chambers. Compared with Embodiment 3, in this embodiment, one end of the branch air pipe 23 away from the main air intake pipe 22 is connected to one end of multiple sub-bronches 24, and the other ends of the multiple sub-bronches 24 are connected to the corresponding multiple air chambers. An air pressure regulating mechanism 21 is installed on each branch air pipe 23, and the air pressure regulating mechanism 21 is controlled to adjust the air intake pressure and air intake volume of the multiple sub-bronches 24 connected to the branch air pipe 23; the air pressure regulating mechanism 21 can also be installed on all the sub-bronches 24 to separately adjust the air intake pressure and air intake volume of the air chamber corresponding to each sub-bronch 24.

[0046] Example 5

[0047] The present embodiment also includes a sieve plate assembly 1, which includes a plurality of sieve plates 12 and a vibration plate 2. A plurality of sieve plates 12 are placed on the vibration plate 2. The plurality of sieve plates 12 are sequentially connected end to end and arranged linearly on the vibration plate 2 to form a plurality of wind chambers with the vibration plate 2. One wind chamber may form a wind chamber unit, or a plurality of wind chambers may form a wind chamber unit. Figure 2 and Figure 4As shown, specifically, the sieve plate 12 includes a first panel 121 and a second panel 122 connected to each other, and a plurality of sieve holes 123 are arranged on the first panel 121, and the plurality of sieve holes 123 are evenly distributed in an array on the first panel 121, so that the airflow blown out of the wind chamber through the sieve holes 123 remains uniform. The aperture of the sieve holes 123 can be determined according to the fineness of the material screening, and the aperture can be set to 1mm-2mm.

[0048] One end of the first panel 121 is connected to one end of the second panel 122 to form a bending portion, and the bending portion can be formed by connecting one end of the first panel 121 and one end of the second panel 122 by welding or integral molding. In this embodiment, the first panel 121 and the second panel 122 are integrally formed, and the outer surface of the bending portion is arc-shaped, which is convenient for holding, and the sieve plate 12 is placed on the vibration disk 2. The end of the first panel 121 away from the second panel 122 is connected to the second panel 122 of the adjacent sieve plate 12, and the connection is away from the bending portion. Specifically, when the sieve plate 12 is placed on the vibration disk 2, the second panel 122 is in a vertical state with the vibration disk 2, and the upper surface of the second panel 122 is parallel to the vibration disk 2; the end of the first panel 121 away from the second panel 122 is provided with a flange 121a that matches the upper surface of the second panel 122, and the flange 121a is also parallel to the vibration disk 2, so that the connection between the two adjacent sieve plates 12 is sealed.

[0049] Sealing plates are arranged around the vibration disk 2 to ensure the sealing of the wind chamber. A front sealing plate 13 and a rear sealing plate 14 are respectively arranged at both ends of the connection of multiple parallel sieve plates 12. A through hole is opened on the front sealing plate 13, and the air supply component is connected to the wind chamber through the through hole to blow air into the wind chamber. The bending portion abuts against the surface of the vibration disk 2, and the closed space surrounded by the first panel 121, the bending portion, the vibration disk 2, the second panel 122 of the adjacent sieve plate 12, the front sealing plate 13 and the rear sealing plate 14 forms a wind chamber.

[0050] In order to further improve the sealing performance of the air chamber, sealant may be applied to the joints between the sieve plate 12 and the front sealing plate 13 and the rear sealing plate 14, so that the sieve plate 12 is tightly connected to the front sealing plate 13 and the rear sealing plate 14. Sealant may also be applied to the upper surface of the second panel 122, so that the upper surface of the second panel 122 is tightly connected to the flange 121a of the first panel 121, so as to improve the sealing performance of the air chamber.

[0051] There are many angles formed by the bending part, and the angle determines the angle formed by the first panel 121 and the vibration disk 2; the sieve hole 123 is arranged on the first panel 121, so it also determines the angle of the airflow blown out of the wind chamber from the sieve hole 123. The angle of the bending part can be set to 30°-80°. After a large number of tests, it is found that the angle of the bending part is set to 70°. At this time, the second panel 122 is perpendicular to the vibration disk 2, the angle between the first panel 121 and the vibration disk 2 is 20°, and the ejection direction of the airflow blown out of the sieve hole 123 is 70° with the vibration disk 2. The airflow blown out of the sieve hole 123 in the wind chamber has the best screening effect on the material.

[0052] In some feasible embodiments, a total air pressure regulating valve may be provided on the total air intake pipe 22. By controlling the total air pressure regulating valve, the opening or closing of the air supply to all the air chambers may be controlled simultaneously.

[0053] In some feasible embodiments, the air pressure regulating mechanism 21 can be one or more of an air pressure regulating valve or an electromagnetic valve. For the convenience of control, the air pressure regulating mechanism 21 of this embodiment selects an air pressure regulating valve, and the air pressure regulating valve can be provided with a wireless module such as Bluetooth to be interconnected with a terminal device such as a mobile phone. The air pressure and switch of each air pressure regulating valve can be wirelessly controlled by operating the mobile phone to adjust the airflow size of the corresponding air chamber unit.

[0054] In the embodiment, the number of sieve plates 12 provided on the vibration disk 2 may be ten or twenty, etc. In the present embodiment, thirty sieve plates 12 are placed on the vibration disk 2, and the thirty sieve plates 12 are connected end to end in sequence in the length direction thereof, forming a total of thirty wind chambers. According to the volume of the material to be screened, different numbers of wind chambers can be selected to form a wind chamber unit. In the present embodiment, every five adjacent wind chambers are selected from the starting position as a wind chamber unit, and thirty wind chambers can form six wind chamber units. The five wind chambers of each wind chamber unit are respectively connected to one end of five sub-bronchial tubes 24, and the other ends of the five sub-bronchial tubes 24 are connected in series to one end of a branch air pipe 23, and the other ends of the six branch air pipes 23 are connected in series to one end of a main air intake pipe 22, and the other end of the main air intake pipe 22 is connected to a high-pressure air compressor 25. The high-pressure air compressor 25 directs the air flow from the main air inlet pipe 22 , the branch air pipe 23 , and the sub-branch pipe 24 to the wind chamber in sequence, blows air into the wind chamber, and screens the material through the sieve holes 123 on the sieve plate 12 .

[0055] like Figure 3As shown, in actual operation, the vibration plate 2 can be adjusted to an inclined state, the direction in which the first panel 121 and the second panel 122 of the screen plate 12 are connected is on the lower side, and the direction in which the first panel 121 and the adjacent second panel 122 are connected is on the higher side. Under the simultaneous action of the vibration plate 2 vibrating and the sieve holes 123 blowing, the light material moves toward the lower side of the vibration plate 2, and finally accumulates on the screen plate 12 near the right side of the vibration plate 2, and the heavier material moves toward the higher side of the vibration plate 2. A heavy material discharge port can be installed on the higher side of the vibration plate 2 for taking out the heavy material; and a light material discharge port can be installed on the lower side of the vibration plate 2 for taking out the light material.

[0056] like Figure 5 As shown, this embodiment is also provided with a recovery component 3. Since fine materials in the material will fall from the sieve hole 123 into the wind chamber during the screening process, the recovery component 3 is used to recover the remaining fine materials. The recovery component 3 includes a pneumatic ball valve 31, a discharge trough 32 and a recovery pipe 33. The pneumatic ball valve 31 is connected to the vibration plate 2 through the discharge trough 32. Specifically, the vibration plate 2 is connected with a discharge trough 32, and the discharge trough 32 is also connected to the recovery pipe 33. When the fine materials are recovered, the rear sealing plate 14 at the end of the sieve plate 12 can be removed first, so that the wind chamber on the vibration plate 2 is connected with the discharge trough 32. When the pneumatic ball valve 31 is opened, the fine aggregate moves from the wind chamber to the discharge trough, and then moves from the discharge trough to the recovery pipe. The recovery pipe is also connected to a recovery chute. After the fine materials flow into the recovery chute, they can be connected to a conveyor belt and transferred to the fine aggregate bin for recycling. A pneumatic valve is also installed on the pneumatic ball valve, which is used to adjust the air pressure of the pneumatic ball valve. When a large amount of material accumulates in the air chamber, the pneumatic valve can be adjusted to provide sufficient adsorption force to recover the material.
