Description

Technical Field

[0001] This utility model relates to a device for removing impurities, and more particularly to a device for screening iron filings and impurities in cable insulation materials. Background Technology

[0002] Cable insulation is a key material used to wrap cable conductors, prevent current leakage, and ensure safe power transmission. It includes cross-linked polyethylene, etc.

[0003] The production process of related cable insulation materials requires mixing, plasticizing, extrusion and granulation. Iron filings are inevitably introduced into these processes. The main reasons for the introduction of iron filings include: falling in from the outside, being carried by the raw materials themselves, and falling in due to screw collisions during mixing or being broken by the cutter during pelletizing. However, the screening of related iron filings removal devices is not thorough and has low screening efficiency. Utility Model Content

[0042] Example 1

[0043] like Figure 1 This embodiment provides a cable insulation material iron filings impurity screening device, including a first screening component 1, a second screening component 2 and a third screening component 3 connected in sequence along the gravity direction; the first screening component 1 includes: a buffer chamber 11 with an inlet 111 at one end, the other end of the buffer chamber 11 being connected to the second screening component 2; a buffer diversion screen 12, a tower-shaped magnetic frame 13 and a valve 14 connected in sequence along the gravity direction inside the buffer chamber 11.

[0044] Specifically, during operation, cable insulation material containing iron filings (hereinafter referred to as the material to be screened) enters the buffer chamber 11 through inlet 111 and flows sequentially through the buffer diversion screen 12, the tower-shaped magnetic frame 13, the valve 14, the second screening component 2, and the third screening component 3 under the action of gravity.

[0045] The buffer chamber 11 has a removable top cover, which facilitates the disassembly and cleaning of the buffer diversion screen 12 and the tower-shaped magnetic frame 13. The buffer diversion screen 12 is convenient for screening large iron filings and impurities, and it also helps to reduce the speed of the material to be screened, preventing the subsequent material to be screened from washing away the iron filings and impurities adsorbed on the tower-shaped magnetic frame 13, thereby preventing the iron filings and impurities from falling off again, and thus making the screening more thorough. The buffer diversion screen 12 is preferably connected to the buffer chamber 11 by a retaining ring. The tower-shaped magnetic frame 13 is used to adsorb iron filings and impurities in the material to be screened. The valve 14 is used to control the flow rate of the material to be screened. The first screening component 1, the second screening component 2, and the third screening component 3 perform triple screening, which further facilitates the screening to be more thorough. At the same time, it also has the advantage of high screening efficiency compared to manual screening.

[0046] Furthermore, such as Figure 2 The tower-shaped magnetic frame 13 includes: a frame 131 connected to the buffer chamber 11; and a plurality of magnetic units 132 arranged sequentially along the direction of gravity, wherein the magnetic units 132 are connected to the frame 131.

[0047] Specifically, the frame 131 is used to support the magnetic unit 132; the magnetic unit 132 is used to adsorb iron filings and impurities in the material to be screened. The number of magnetic units 132 is not limited and can be three, four, etc.

[0048] Furthermore, such as Figure 2 Each magnetic unit 132 includes several parallel magnetic rods 1321, which are connected to the frame 131.

[0049] Specifically, the magnetic rod 1321 is used to adsorb iron filings and impurities in the material to be screened. The number of magnetic rods 1321 is not limited and can be three, four, etc. When connecting, two mounting holes can be opened on both sides of the frame 131, and the magnetic rods 1321 can be passed through the two mounting holes to ensure installation stability.

[0050] Furthermore, such as Figure 1 It also includes: a feeder 42; a feed pipe 41 connected to one end of the feeder 42; and several branch pipes 43, all connected between the other end of the feeder 42 and the inlet 111.

[0051] Specifically, during material feeding, the feeder 42 is activated, allowing the material to be screened to pass sequentially through the feed pipe 41, the feeder 42, the diversion pipe 43, and the inlet 111 into the buffer chamber 11. The feeder 42 can be a vacuum type, a pneumatic conveying type, etc. Several diversion pipes 43 facilitate the uniform entry of the material to be screened into the buffer chamber 11. The number of diversion pipes 43 is not limited and can be three, four, etc.

[0052] Furthermore, such as Figure 1It also includes: a vent 112 located in the buffer chamber 11; and a material level observation window 15 connected to the buffer chamber 11.

[0053] Specifically, the vent 112 facilitates the balance of internal and external air pressure in the buffer chamber 11; the material level observation window 15 facilitates the observation of material level.

[0054] Furthermore, such as Figure 1 The second screening component 2 includes: an intermediate compartment 21 connected between the other end of the buffer compartment 11 and the third screening component 3; a plurality of limiting pins 22 all connected to the intermediate compartment 21; a conical magnetic frame 23, the large-diameter end of the conical magnetic frame 23 cooperating with the limiting pins 22; a plurality of magnetic rods 24 all connected to the conical magnetic frame 23; and a lifting ring 25 connected to the small-diameter end of the conical magnetic frame 23.

[0055] Specifically, the limiting pin 22 is used to support the conical magnetic frame 23 and facilitates the formation of a gap between the large-diameter end of the conical magnetic frame 23 and the intermediate chamber 21, thereby facilitating the flow of the material to be screened; the conical magnetic frame 23 is equipped with several magnetic rods 24 to increase the contact area between the material to be screened and the magnetic rods 24, thereby facilitating thorough screening; the lifting ring 25 facilitates the disassembly and assembly of the conical magnetic frame 23.

[0056] Furthermore, such as Figure 1 The other ends of the intermediate compartment 21 and the buffer compartment 11 are detachably connected by a clamp 5.

[0057] Specifically, the detachable connection facilitates timely disassembly and cleaning of the conical magnetic frame 23 and the magnetic rod 24.

[0058] Furthermore, such as Figure 1 The third screening component 3 includes: a funnel-shaped flow-gathering chamber 31, one end of which is connected to the second screening component 2, and the other end of which is provided with an outlet 311; and several magnetic blocks 32 connected to the funnel-shaped flow-gathering chamber 31.

[0059] Specifically, the funnel-shaped flow-gathering chamber 31 facilitates the collection of the material to be screened, and, together with several magnetic blocks 32, further adsorbs iron filings and impurities in the material to be screened; the outlet 311 facilitates the discharge of the material to be screened.

[0060] Furthermore, such as Figure 1 One end of the funnel-shaped flow collection chamber 31 and the second screening component 2 are detachably connected via the flange assembly 6.

[0061] Specifically, the detachable connection facilitates timely disassembly and cleaning of the funnel-shaped flow-gathering chamber 31 and the magnetic block 32.

[0062] Furthermore, such as Figure 1The valve 14 includes: an airbag-type flow restrictor valve 143 located at the other end of the buffer chamber 11; an inlet valve 141 and an exhaust valve 142 respectively connected to the two ends of the airbag-type flow restrictor valve 143.

[0063] Specifically, the smaller the expansion degree, the larger the gap between the airbag-type flow limiting valve 143 and the other end of the buffer chamber 11, and the faster the feeding speed. The larger the expansion degree, the smaller the gap and the slower the feeding speed, which makes it easier to control the feeding speed of the material to be screened.

[0064] The above embodiments only illustrate several implementation methods of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
