Description

Technical Field

[0001] The utility model relates to the field of feeding equipment, in particular to an automatic feeding equipment for powdery materials. Background Art

[0002] Currently, for powdered materials (such as lime powder, powdered feed, etc.), after the materials are prepared, they need to be placed in containers for subsequent processing or transportation.

[0003] In existing technologies, when powdered materials are placed in containers, a large amount of dust is generated. These fine dust particles easily enter the lungs through breathing. Long-term inhalation of dust can lead to pulmonary fibrosis and pneumoconiosis, such as silicosis and coal worker's pneumoconiosis. These diseases can gradually reduce lung function, causing symptoms such as coughing, sputum production, shortness of breath, and chest tightness, seriously affecting patients' quality of life and ability to work, and even leading to respiratory failure. Furthermore, when dust from powdered materials reaches a certain concentration in the air, it can cause a dust explosion when it encounters an ignition source such as fire or static electricity. Dust explosions are instantaneous and highly destructive, generating enormous impact force and heat, causing severe damage to production equipment and factory buildings, and even causing fires, resulting in casualties and significant property losses. For example, dust explosions have occurred in flour mills, coal mines, and metal processing plants. Utility Model Content

The terms used in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0026] In addition, the technical features involved in different embodiments of the present application described below can be combined with each other as long as they do not conflict with each other.

[0027] The preferred embodiments of the present invention will now be further described with reference to the accompanying drawings. Figure 1 As shown, an automatic feeding device for powdered materials includes a first conveying track 100 and a feeding channel 200. Support covers 500 are provided on both sides of the first conveying track 100. The feeding channels 200 are provided on the support covers 500. The number of the feeding channels 200 is four and they are arranged in a rectangular shape. A supporting plate 300 is provided on the first conveying track 100. The supporting plate 300 is in sliding contact with the first conveying track 100, that is, the supporting plate 300 can slide along the first conveying track 100. A material barrel 400 for filling powdered materials is placed on the top of the supporting plate 300. The feeding channel 20 0 is provided with a discharge port 210 at the bottom, and the discharge port 210 is provided above the material barrel 400. The number of the material barrels 400 is four and they are distributed on the support plate 300 corresponding to the feed channel 200, that is, when the material barrel 400 moves to the bottom of the feed channel 200 through the first conveying track 100, the feed barrel and the feed channel 200 form a one-to-one correspondence from top to bottom, and an electrically connected exhaust device 600 and a dust detection device 610 are provided on the top of the support cover 500, the exhaust device 600 is communicated with the inside of the support cover 500, and an exhaust port 620 is provided on the top of the exhaust device 600.

[0028] In the initial state of this embodiment, the support plate 300 with the material barrel 400 is first placed on the first conveying track 100 outside the conveying channel 200 by a forklift, and then the first conveying track 100 is started to move the support plate 300 to the bottom of the conveying channel 200, so that the material barrel 400 forms a one-to-one correspondence under the conveying channel 200, and then the conveying channel 200 is started to pour the external powdered material into the material barrel 400, thereby completing the entire feeding and loading process. During the loading process, when the dust detector When the device 610 detects that the dust pressure inside the support cover 500 is too high, it sends an electrical signal to the exhaust device 600, starts the exhaust device 600 to extract the dust inside the support cover 500 and discharge it through the exhaust port 620. It should be noted that the sliding contact between the support plate 300 and the first conveying track 100 described in this application can be achieved by rollers provided on the first conveying track 100, or other components that can allow the support plate 300 to roll on the first conveying track 100. This is an existing conventional structure and will not be further described here.

[0029] It can be seen from the above embodiments that compared with the prior art, the present application sets four feeding channels 200 above the first conveying track 100, and places material barrels 400 corresponding to their positions on the support plate 300, so that the material feeding efficiency is improved several times compared with the efficiency of the previous single material barrel 400. In addition, the present application uses the exhaust device 600 and the dust detection device 610 to extract the accumulated dust in the support cover 500 in time to prevent the feeding channel 200 from pouring external powdered materials into the material barrel 400 during the loading process, and prevents dust from accumulating in the support cover 500 and causing dust explosions.

[0030] Further to the above embodiment, Figure 1 As shown, a limiting assembly 310 for fixing the material barrel 400 is provided on the supporting plate 300 , and the limiting assembly 310 is used to prevent the material barrel 400 from falling from the supporting plate 300 when the material barrel 400 moves on the first conveying track 100 .

[0031] Further to the above embodiment, Figure 2 As shown, the limiting assembly 310 includes limiting plates 311 arranged around the material barrel 400 at intervals of 90 degrees, and surface contact is formed between the limiting plates 311 and the outer wall of the material barrel 400. In this way, when the material barrel 400 moves on the first conveying track 100, it is clamped on all sides by the limiting plates 311, so it can be prevented from falling from the support plate 300. In addition, the number of limiting plates 311 is four, which can also avoid the problem of too many limiting plates 311 being set, which makes it difficult to place the material barrel 400 between the limiting plates 311.

[0032] Further to the above embodiment, Figure 3 As shown, the limiting plate 311 includes a contact portion 311a and a buffer portion 311b. The contact portion 311a is directly perpendicularly arranged to the support plate 300 and forms a surface contact with the outer wall of the material barrel 400. The buffer portion 311b is offset along the contact portion 311a in a direction away from the material barrel 400, thereby forming a certain angle with the outer wall of the material barrel 400. When the material barrel 400 tilts during its movement on the first conveying track 100, the buffer portion 311b can form a surface contact with the outer wall of the material barrel 400, thereby reducing the pressure on the contact portion 311a.

[0033] Further to the above embodiment, Figure 4 As shown, a reinforcement portion 311c is provided on the back of the contact portion 311a of the limiting plate 311 in the middle of the material barrel 400, and the reinforcement portions 311c are connected to each other. In this way, when the material barrels 400 tilt toward each other during movement, the reinforcement portion 311c can provide reinforcement support for the surface contact formed between the contact portion 311a and the outer wall of the material barrel 400.

[0034] In some implementations, such as Figure 2 As shown, a pair of through slots 312 are opened on the side of the bottom of the support plate 300. The opening direction of the through slots 312 is perpendicular to the laying direction of the first conveying track 100. The through slots 312 are used to facilitate the insertion of forklift forks when the support plate 300 is transported by a forklift.

[0035] In some implementations, such as Figure 2 As shown, a groove 313 is provided at the bottom of the supporting plate 300. When the supporting plate 300 is placed on the first conveying track 100, the first conveying track 100 is embedded in the groove 313 to form a sliding contact therewith, thereby facilitating the supporting plate 300 to slide on the first conveying track 100.

[0036] Further to the above embodiment, Figure 5 As shown, a second conveying track 110 is further provided outside the first conveying track 100. When the support plate 300 is used to place the heavy material drum 400, since the second conveying track 110 is provided outside the first conveying track 100, the spacing between the second conveying tracks 110 is larger, so that the support plate 300 can move more stably when placed thereon.

[0037] The above exemplary embodiments are detailed, and the present invention may be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the present invention is defined by the appended claims rather than the foregoing description, and it is intended that all changes that come within the meaning and range of equivalents of the claims be included within the present invention.
