Description

Technical Field

[0001] The utility model belongs to the field of non-metallic mineral processing, and particularly relates to an environmentally friendly blanking column. Background Art

[0002] As the primary building material for structures like concrete and masonry, sand and gravel aggregate (hereafter referred to as aggregate) is an indispensable and irreplaceable raw material in construction. Aggregate production and processing involves multiple steps, including crushing, screening, storage, and transportation, and is subject to increasingly stringent environmental protection requirements.

[0003] Currently, bag dust removal systems, micro-mist dust suppression systems, fog cannon dust removal systems, etc. are used for dust removal. However, when it comes to the landing of aggregate products, direct landing is mostly used, which results in a lot of dust. The dust removal effect of micro-mist dust suppression, fog cannon dust removal, windproof dust suppression nets or a combination of these methods is poor. At the same time, the aggregate has a great impact and damage on the piled ground. Utility Model Content

[0004] The purpose of this utility model is to provide an environmentally friendly blanking column to overcome the above technical defects.

[0005] In order to solve the above technical problems, the utility model provides an environmentally friendly blanking column, comprising:

[0006] The column is a hollow column structure, the bottom of which is detachably fixed to the ground, and the top of which is open for receiving aggregate;

[0007] A discharge window is opened on the column wall of the column, and a discharge window cover is installed on the discharge window. The aggregate in the column is gradually piled up and the discharge window cover is pushed open, so that the aggregate in the column is scattered out of the discharge window cover.

[0008] According to an environmentally friendly drop column, a column foundation is fixed on the ground;

[0009] The column bottom of the column is detachably fixed to the column foundation.

[0010] According to an environmentally friendly drop column, the column foundation is cast using reinforced concrete;

[0011] The column bottom of the column is fixed to the column foundation through column foot bolts.

[0012] According to an environmentally friendly drop column, the top opening of the column body serves as a receiving port for receiving the aggregate transported by a belt;

[0013] The material receiving port is in the form of an inverted frustum trumpet.

[0014] According to an environmentally friendly blanking column, the receiving port and the column body are split structures;

[0015] The small-diameter end of the receiving port is mounted on the top of the column through a flange;

[0016] The large-diameter end of the material receiving port is located below the belt head wheel, the lower hopper of the belt head wheel is covered in the material receiving port, and the material receiving port does not contact the lower hopper.

[0017] According to an environmentally friendly drop column, the number of the column is at least one;

[0018] When the number of the columns is more than two, two upper and lower adjacent columns are firmly connected.

[0019] According to an environmentally friendly discharge column, a plurality of rows of discharge windows are provided on the column wall from top to bottom;

[0020] The number of the discharge windows in each row is at least one, and all the discharge windows in each row are arranged at equal intervals along the circumferential direction.

[0021] According to an environmentally friendly discharge column, the discharge window cover is installed on the column wall of the column through a latch connector to cover or expose the discharge window.

[0022] The utility model proposes an environmentally friendly drop column suitable for the landing of aggregate products. The environmentally friendly drop column mainly comprises a hollow column arranged below the outlet of the belt conveyor, and a discharge window is opened on the column wall of the hollow column. Aggregates conveyed by the belt fall into the hollow column through the receiving port. When the aggregates in the hollow column reach the discharge window, the discharge window cover is gradually opened, and the aggregates are dispersed out of the pile. Since the speed is close to 0, there is very little dust, which solves the problems of large dust and dust diffusion when the aggregates are dropped, and the significant impact and damage to the piled ground.

[0028] The following describes the implementation of the present invention through specific embodiments. Those skilled in the art can easily understand other advantages and effects of the present invention from the contents disclosed in this specification.

[0029] It should be noted that, in the present invention, the upper, lower, left and right in the figure are regarded as the upper, lower, left and right of the environmentally friendly blanking column described in this specification.

[0030] Exemplary embodiments of the present invention will now be described with reference to the accompanying drawings. However, the present invention may be implemented in many different forms and is not limited to the embodiments described herein. These embodiments are provided to provide a detailed and complete disclosure of the present invention and to fully convey the scope of the present invention to those skilled in the art. The terms used in the exemplary embodiments shown in the accompanying drawings are not intended to limit the present invention. In the accompanying drawings, identical elements are denoted by the same reference numerals.

[0031] Unless otherwise specified, the terms used herein (including technical and scientific terms) have the meanings commonly understood by those skilled in the art. Furthermore, it is understood that terms defined in commonly used dictionaries should be understood to have meanings consistent with the context of their relevant fields and should not be interpreted as idealized or overly formal.

[0032] This embodiment relates to an environmentally friendly drop column, which is suitable for the landing link of aggregate products and is arranged below the outlet of the belt conveyor. Figure 1 or Figure 2 The environmentally friendly blanking column includes a column body 20 and a discharge window.

[0033] The column 20 is a hollow column structure with a removable bottom fixed to the ground and an opening at the top for receiving aggregate. The column 20 is a cylindrical hollow steel column. Aggregates from the belt conveyor fall into the column 20 and gradually pile up inside the column 20.

[0034] It should be noted that after the first drop, the aggregate will form a buffer layer at 1m~1.2m at the bottom of the column 20, which can reduce the impact of subsequent drop on the ground; once formed, this cushion layer can be reused.

[0035] In some embodiments, as Figure 1 and Figure 2 As shown, a column foundation 10 is fixed on the ground, and the column base 20 is detachably fixed to the column foundation 10. The column foundation 10 is fixed on the ground to ensure the stability and reliability of the entire environmentally friendly blanking column.

[0036] In some embodiments, column foundation 10 is cast using reinforced concrete, and the base of column 20 is secured to column foundation 10 via high-strength bolts / column foot bolts. High-strength bolts are made of high-strength steel (e.g., Q235). Bolts with a performance grade of 8.8 or higher are considered high-strength bolts.

[0037] In some embodiments, as Figure 1 and Figure 2 As shown, the top opening of the column 20 serves as a receiving port 50 for receiving aggregates transported by the belt. The receiving port 50 is in the form of an inverted frustum trumpet to ensure smooth discharge of aggregates. Specifically:

[0038] The aggregate is transported by the belt and falls to the receiving port 50. Before hitting the receiving port 50, it hits the belt head wheel cover and is decelerated once. After hitting the receiving port 50, it is decelerated twice. After the second deceleration, the aggregate is guided by the receiving port 50 and all changes to vertical falling motion and falls into the inside of the column 20.

[0039] In some embodiments, as Figure 1 and Figure 2 As shown, the receiving port 50 and the column 20 are split structures. The small-diameter end of the receiving port 50 is installed on the top of the column 20 through a flange, and the large-diameter end of the receiving port 50 is located below the belt head pulley. The lower hopper of the belt head pulley is covered in the receiving port 50, and the receiving port 50 does not contact the lower hopper. The purpose is to ensure that the aggregate in the lower hopper falls completely into the receiving port 50, while also reducing dust.

[0040] The discharge window is opened on the column wall of the column 20, and a discharge window cover 30 is installed on the discharge window. The aggregate in the column 20 gradually piles up and pushes the discharge window cover 30 open, so that the aggregate in the column 20 is dispersed out of the discharge window cover 30.

[0041] When the height of the aggregate inside the column 20 reaches the lower edge of the discharge window, the discharge window cover 30 is gradually opened, and the aggregate is scattered outward in an extrusion-type manner with a speed close to 0 and very little dust, forming the first layer of aggregate through this discharge window.

[0042] According to the height of the belt outlet, the number of the columns 20 is at least one. When the number of the columns 20 is two or more, the two upper and lower adjacent columns 20 are firmly connected, which can be connected by flange, welding, or other connection methods.

[0043] In some embodiments, multiple rows of unloading windows are opened on the column wall of the column 20 from top to bottom, the number of unloading windows in each row is at least one, and all unloading windows in each row are arranged at equal intervals along the circumferential direction, such as opening three unloading windows at the same height and equal circumferential distance.

[0044] From bottom to top, each row of unloading windows is numbered as the first row of unloading windows, the second row of unloading windows, etc.

[0045] When the aggregate pile inside the column 20 reaches a certain amount, the first row of discharge windows will no longer discharge aggregate, and the pile inside the column 20 will gradually increase in height until it reaches the lower edge of the second row of discharge windows, and then continue to disperse the aggregate to form the second layer of aggregate. This process continues in this way, gradually forming the third layer of aggregate until it reaches the highest row of discharge windows.

[0046] The pile descends: when the front end belt stops conveying aggregate and the aggregate is gradually transported out of the yard, the height of the external conical pile gradually decreases, the unloading window gradually becomes exposed, and the unloading window cover 30 gradually closes and returns to normal.

[0047] In some embodiments, the discharge window cover 30 is mounted on the column wall of the column 20 via a latch connector 40 to cover or expose the discharge window. That is, the discharge window cover 30 can be flipped around the latch connector 40. The installation position of the latch connector 40 is shown in FIG. Figure 1 and Figure 2 .

[0048] In summary, the process of processing aggregates with environmentally friendly drop columns is as follows:

[0049] (100) Secondary deceleration and change of direction: The aggregate is transported by the belt and falls to the receiving port 50. Before hitting the receiving port 50, it hits the belt head wheel cover and is decelerated once. After hitting the receiving port 50, it is decelerated twice. After the second deceleration, the aggregate is guided by the receiving port 50 and changes direction to vertical falling motion, falling into the inside of the column 20.

[0050] (200) Formation of a cushion layer: After the first drop of material, the aggregate will form a cushion layer at 1m~1.2m at the bottom of the column 20. This cushion layer can reduce the impact of subsequent drop of material on the ground; once formed, this cushion layer can be reused.

[0051] (300) The first layer of material stacking: When the height of the aggregate inside the column 20 reaches the lower edge of the first row of unloading windows, the unloading window cover 30 is gradually opened, and the aggregate is scattered outward in an extrusion-type manner with a speed close to 0 and very little dust, forming the first layer of material stacking through this unloading window.

[0052] (400) Second layer of material: When the aggregate material inside the column 20 reaches a certain amount, the first row of discharge windows will no longer discharge material. The material inside the column 20 will gradually increase in height until it reaches the lower edge of the second row of discharge windows. Then, the material will continue to disperse outwards, forming the second layer of material. This process will continue until the third layer of material is formed, reaching the highest row of discharge windows.

[0053] (500) Material pile descent: When the front end belt stops conveying aggregate and the aggregate in the yard is gradually transported out, the height of the external conical material pile gradually decreases, the unloading window gradually becomes exposed, and the unloading window cover 30 gradually closes and returns to normal.

[0054] Environmentally friendly drop columns are suitable for the dropping of aggregate products. They primarily consist of a hollow column positioned below the conveyor belt outlet, with a discharge window defined in its wall. Aggregate conveyed by the belt falls through the receiving port into the hollow column. When the aggregate inside the hollow column reaches the discharge window, the window cover gradually opens, allowing the aggregate to disperse. Because the velocity is close to zero, dust is minimal, eliminating the issues of high dust levels, dust diffusion, and significant impact damage to the piled floor.

[0055] Those skilled in the art will appreciate that the above-mentioned embodiments are specific examples for implementing the present invention, and in actual applications, various changes may be made thereto in form and detail without departing from the spirit and scope of the present invention.
