Description

Technical Field

[0001] The present invention relates to a bulk loader for building materials, in particular to a bulk loader for building materials applied in the field of bulk loader. Background Art

[0002] Bulk material handling equipment is a mechanical equipment used to transport and process various bulk materials, and is widely used in ports, mines, chemicals and other industries. The design and application of these equipment are of great significance to improving logistics efficiency and reducing labor intensity. During the loading and unloading process, since cement clinker is mostly powder, dust will inevitably be generated during unloading, affecting the environment of the bulk site.

[0003] The specification of Chinese invention patent CN105819243B discloses a dust removal system for a mobile bulk bagged cement loader. This invention can prevent the escape of dust generated during the falling process of bagged cement, greatly improving the dust collection effect.

[0004] The above-mentioned bulk loader dust prevention equipment uses a flexible cover curtain to prevent the spread of dust. However, there is a gap between the size of the cover curtain and the size of the loading barrel. This results in a gap between the flexible cover curtain and the loading barrel during unloading, which makes it easy for dust to spread into the gap. After loading is completed, the flexible cover curtain is retracted, and the dust accumulated in the area near the loading barrel will be raised again as the loading truck moves, forming dust, which in turn affects the environment of the bulk loading site. Summary of the invention

[0005] In view of the above-mentioned prior art, the technical problem to be solved by the present invention is how to avoid the occurrence of dust before and after bulk loading operations, thereby protecting the bulk loading site environment.

[0006] In order to solve the above problems, the present invention provides a building material bulk loader, including a bulk platform, a Roots blower is installed on the top of the bulk platform, a feed port is installed through the top of the bulk platform, a discharge barrel with a top and a bottom of the feed port connected is installed at the bottom of the bulk platform, a conical bucket is installed at the bottom of the discharge barrel, a dust cover curtain located outside the conical bucket is installed at the bottom of the discharge barrel, a closing unit is installed on the inner side of the dust cover curtain, the closing unit includes a two-way electric telescopic rod, and the tail end of the two-way electric telescopic rod is fixedly connected to the inner wall of the dust cover curtain, a pull rope is connected to the tail end surface of the two-way electric telescopic rod, and the tail end of the pull rope is connected to a closing structure located outside the conical bucket, the closing structure includes a plurality of arc-shaped rubber covers, an electromagnetic film is installed inside the rubber cover, through grooves are provided on the two end surfaces of the rubber cover, a spring bar is connected inside one of the through grooves, and the tail end of the spring bar is connected to the inner wall of the through groove in the adjacent rubber cover, a surrounding hook ring is installed on the surface of the conical bucket, and the pull rope runs through the inside of the hook ring.

[0007] In the above-mentioned building material bulk loader, by installing a dust curtain and a sealing unit, the dust curtain restrictively seals the inside of the loading port, controls the dust range within the docked dust curtain, and prevents the occurrence of secondary dust accidents.

[0008] As a further improvement of the present application, the dust cover curtain is made of a flexible material, and a flexible filter screen is bonded to the inner wall of the dust cover curtain, and the height of the dust cover curtain is greater than the cross-sectional height of the conical bucket.

[0009] As a further improvement of the present application, the end of the bidirectional electric telescopic rod is located below the bottom of the conical bucket, a distance sensor is installed at the bottom of the rubber cover, and the distance sensor, the bidirectional electric telescopic rod and the electromagnetic film are electrically connected.

[0010] As a further improvement of the present application, the number of rubber covers is an even number, and there is a magnetic repulsion effect between the electromagnetic soft films in two rubber covers on the same central axis.

[0011] As a further improvement of the present application, the inner diameter of the closed structure is not greater than the radius at the half height position of the conical bucket, and the hook ring is located above the closed structure.

[0012] As a further improvement of the present application, the connection position between the two-way electric telescopic rod and the dust cover curtain is located near the bottom of the inner wall of the dust cover curtain, and the surface of the two-way electric telescopic rod is coated with an anti-stick coating.

[0013] As another improvement of the present application, the outer surface of the rubber cover is provided with a strip-shaped depression, and the inner wall of the strip-shaped depression is installed with an anti-slip magnetic rod through an axis rod, and an electromagnetic shielding soft board and an electromagnetic soft film 2 are installed inside the rubber cover, and the electromagnetic soft film 2 and the electromagnetic soft film 1 are symmetrically arranged about the electromagnetic shielding soft board, and there is a magnetic repulsion effect between the electromagnetic soft film 2 and the anti-slip magnetic rod.

[0014] As another improved supplement of the present application, the length of the strip-shaped depression is smaller than the length of the rubber cover, and the length of the anti-slip magnetic rod is larger than the length of the rubber cover, the tail end of the strip-shaped depression passes through the bottom of the rubber cover, and the surface of the anti-slip magnetic rod is provided with anti-slip grooves.

[0015] To summarize, the present invention is equipped with a dust curtain and a sealing unit. When performing bulk loading operations, the two-way electric telescopic rod is first started to shrink the tail end of the dust curtain so that the tail end of the dust curtain can be inserted into the interior of the loading port. At the same time, as the two-way electric telescopic rod is retracted, the sealing structure rises to a position near the top of the loading port. Subsequently, the electromagnetic soft film is started to use the outward expansion deformation to drive the rubber cover to squeeze the dust curtain, so that the dust curtain restricts the interior of the loading port and seals it, thereby preventing dust from spreading during the unloading of cement clinker. At the same time, the dust range is controlled within the interior of the docked dust curtain to prevent secondary dust accidents. BRIEF DESCRIPTION OF THE DRAWINGS

[0030] Two embodiments of the present application are described in detail below with reference to the accompanying drawings.

[0031] Embodiment 1

[0032] Figure 1-Figure 9 A building material bulk loader is shown, comprising a bulk platform 1, a Roots blower 3 is installed on the top of the bulk platform 1, a feed port 2 is installed through the top of the bulk platform 1, a discharge barrel 4 whose top and the bottom of the feed port 2 are connected is installed at the bottom of the bulk platform 1, a conical bucket 41 is installed at the bottom of the discharge barrel 4, a dust curtain 5 located outside the conical bucket 41 is installed at the bottom of the discharge barrel 4, a closed unit 6 is installed on the inner side of the dust curtain 5, the closed unit 6 comprises a bidirectional electric telescopic rod 61, and the tail end of the bidirectional electric telescopic rod 61 is fixedly connected to the inner wall of the dust curtain 5, and the bidirectional electric telescopic rod 61 is fixedly connected to the inner wall of the dust curtain 5. A pulling rope 62 is connected to the tail end surface of the electric telescopic rod 61, and the tail end of the pulling rope 62 is connected to a closed structure 63 located on the outside of the conical bucket 41. The closed structure 63 includes a plurality of arc-shaped rubber covers 631. An electromagnetic soft film 633 is installed inside the rubber cover 631. Through grooves are provided on the surfaces of both ends of the rubber cover 631. A spring bar 632 is connected to the inside of one of the through grooves, and the tail end of the spring bar 632 is connected to the inner wall of the through groove in the adjacent rubber cover 631. A surrounding hook ring 7 is installed on the surface of the conical bucket 41, and the pulling rope 62 passes through the inside of the hook ring 7.

[0033] The dust-proof curtain 5 is made of a flexible material, and a flexible filter screen is bonded to the inner wall of the dust-proof curtain 5 . The height of the dust-proof curtain 5 is greater than the cross-sectional height of the conical bucket 41 .

[0034] The end of the bidirectional electric telescopic rod 61 is located below the bottom of the conical bucket 41, and a distance sensor is installed at the bottom of the rubber cover 631, and the distance sensor, the bidirectional electric telescopic rod 61 and the electromagnetic film 633 are electrically connected.

[0035] The number of the rubber covers 631 is an even number, and there is magnetic repulsion between the electromagnetic soft films 1 633 in two rubber covers 631 on the same central axis.

[0036] The inner diameter of the closed structure 63 is not greater than the radius of the conical bucket 41 at half the height, and the hook ring 7 is located above the closed structure 63 .

[0037] The connection position between the bidirectional electric telescopic rod 61 and the dust cover curtain 5 is located at a position of the inner wall of the dust cover curtain 5 close to the bottom end, and the surface of the bidirectional electric telescopic rod 61 is coated with an anti-stick coating.

[0038] Specifically, when the bulk loader is used to unload cement clinker in bulk, the loading truck and the loading port on the top of the loading truck travel to the bottom of the conical bucket 41, and the cement clinker enters the inside of the unloading barrel 4 through the feeding port 2 and then enters the loading port through the conical bucket 41, completing the corresponding bulk unloading operation;

[0039] The electromagnetic film 633 is an electromagnetic structure made of elastic material;

[0040] After the loading port is aligned with the bottom of the conical bucket 41, since the diameter of the dust curtain 5 is larger than that of the loading port, it is necessary to start the two-way electric telescopic rod 61 to retract its two ends inward, thereby shortening the ends of the dust curtain 5 so as to enter the interior of the loading port. At the same time, as the length of the two-way electric telescopic rod 61 shortens, the pull rope 62 is pulled accordingly, thereby driving the closed structure 63 that follows the loading port to move up to a position near the top of the loading port. At this time, the distance sensor is used to test the distance between the rubber cover 631 and the two-way electric telescopic rod 61. When the distance value between the bottoms is not less than half of the height value of the loading port, the electromagnetic soft film 633 is activated, and the magnetic repulsion from the electromagnetic soft film 633 at the other end on the same central axis causes the rubber covers 631 in the original closed structure 63 to move away from each other. At the same time, the magnetic repulsion causes the rubber covers 631 to squeeze the dust curtain 5 so that it can better fit the inner wall of the loading port, thereby forming an effective dust protection for the inner wall of the loading port, and preventing the dust from spreading to the surface of the area near the loading port of the loading truck, thereby preventing the occurrence of secondary dust.

[0041] In the above process, the rubber cover 631 has a certain deformable property. When it is squeezed, it can fit the inner wall of the loading port (assuming that the inner wall of the loading port is provided with a depression, the rubber material is convenient for better extrusion and fitting). At the same time, the rubber cover 631 in the diffused and separated state is constrained and connected by the spring bar 632, and can subsequently realize the reset and fitting state of the rubber cover 631.

[0042] In addition, after the loading is completed, the bidirectional electric telescopic rod 61 is started back and forth with a small amplitude, driving the bottom end of the dust cover curtain 5 to shake, thereby shaking the dust adhering to the inner wall of the dust cover curtain 5 and causing it to fall into the inside of the loading port, thereby achieving the corresponding dust removal effect and preventing the waste of cement clinker.

[0043] Embodiment 2

[0044] Figure 10-12 It is shown that the outer surface of the rubber cover 631 is provided with a strip-shaped depression, and the inner wall of the strip-shaped depression is installed with an anti-slip magnetic rod 636 through an axis rod, and the inside of the rubber cover 631 is installed with an electromagnetic shielding soft board 634 and an electromagnetic soft film 2 635, and the electromagnetic soft film 2 635 and the electromagnetic soft film 1 633 are symmetrically arranged about the electromagnetic shielding soft board 634, and there is a magnetic repulsion effect between the electromagnetic soft film 2 635 and the anti-slip magnetic rod 636.

[0045] The length of the strip-shaped depression is smaller than the length of the rubber cover 631 , and the length of the anti-slip magnetic bar 636 is larger than the length of the rubber cover 631 . The tail end of the strip-shaped depression passes through the bottom of the rubber cover 631 , and the surface of the anti-slip magnetic bar 636 is provided with anti-slip grooves.

[0046] Specifically, in order to enhance the dust removal effect inside the dust curtain 5, when dust removal is needed, the electromagnetic film 2 635 made of the same material as the electromagnetic film 1 633 is activated, and the magnetic repulsion effect generated causes the anti-skid magnetic rod 636 with anti-skid patterns on the surface to tilt outward. By intermittently activating the electromagnetic film 2 635, the anti-skid magnetic rod 636 continuously hits the inner surface of the dust curtain 5, and cooperates with the bidirectional electric telescopic rod 61, which can achieve a more comprehensive shaking dust removal effect on the inside of the dust curtain 5.

[0047] Since the length of the anti-slip magnetic bar 636 is greater than that of the rubber cover 631 , the anti-slip magnetic bar 636 has sufficient length to support when it tilts outward and hits the dust cover curtain 5 .

[0048] In view of current practical needs, the protection scope of the above-mentioned embodiments adopted in this application is not limited thereto. Various changes made within the knowledge scope of technical personnel in this field without departing from the concept of this application still fall within the protection scope of the present invention.
