Description

Technical Field

[0001] This utility model relates to the field of feeding device technology, and in particular to a feeding device for producing building gypsum powder. Background Technology

[0002] Construction gypsum powder is mainly made from natural gypsum or industrial waste. It sets and hardens quickly, and its volume expands slightly during hardening, which ensures that the surface of the product is smooth and the dimensions are accurate. When producing gypsum powder, a screw conveyor is needed to transport the raw materials of gypsum powder to other production equipment.

[0003] The above-mentioned and existing technologies have the following defects: When gypsum powder raw materials are piled up in the hopper of the screw conveyor during the use of the screw conveyor, the raw materials are easily squeezed and come into close contact. As a result, the raw materials cannot come into normal contact with the screw conveyor auger during the subsequent feeding process, which makes it impossible for the screw conveyor to transport the raw materials normally, thereby reducing the practicality of the screw conveyor.

[0004] Therefore, a feeding device for producing building gypsum powder is proposed. Utility Model Content

[0005] The purpose of this invention is to solve the problem that the raw materials cannot properly contact the auger of the screw conveyor, which causes the screw conveyor to be unable to properly transport the raw materials. Therefore, a feeding device for the production of building gypsum powder is proposed.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a feeding device for producing building gypsum powder, comprising a base, a hopper and a relay frame fixedly mounted on the upper surface of the base, a connecting pipe fixedly connected to the lower end of the hopper and the upper surface of the relay frame, a conveying pipe fixedly connected to the side wall of the relay frame, a discharge pipe fixedly connected to the circumferential surface of the conveying pipe, an auger rotatably connected to the inner wall of the relay frame and abutting against the inner wall of the conveying pipe, a feed pipe fixedly connected to the side wall of the hopper, a partition and a spacer ring fixedly mounted on the inner wall of the hopper, a rotating plate rotatably connected to the inner wall of the spacer ring, a connecting ring fixedly mounted between the partition and the spacer ring, a rotating shaft rotatably connected to the inner wall of the hopper, the rotating shaft being fixedly connected to the rotating plate, and a plurality of arch-breaking rods fixedly mounted on the upper surface of the rotating plate.

[0007] The effect achieved by the above components is as follows: by setting up components such as partitions, partition rings, connecting rings, arch-breaking rods and rotating plates, during the production of building gypsum powder, when it is necessary to feed other equipment, the arch-breaking rods can break up the raw materials, thereby facilitating the subsequent conveying of the raw materials and improving the practicality of the screw conveyor.

[0008] Preferably, a sealing plate is fixedly installed on the inner wall of the hopper, the sealing plate abuts against the lower surface of the rotating plate, and both the sealing plate and the rotating plate have material discharge holes.

[0009] The effect achieved by the above components is that when the material discharge holes on the surface of the rotating plate and the sealing plate are misaligned, the raw material will accumulate in the space formed by the rotating plate, the connecting ring and the partition.

[0010] Preferably, a support plate is fixedly mounted on the circumferential surface of the rotating shaft, and a scraper is fixedly mounted on the surface of the support plate, with the scraper abutting against the inner circumferential surface of the connecting ring.

[0011] The effect achieved by the above components is that the support plate rotates with the shaft, which drives the scraper to slide along the inner circumference of the connecting ring. The scraper can scrape off the residual gypsum powder raw material, ensuring clean discharge.

[0012] Preferably, a flange is fixedly mounted on the outer circumferential surface of the rotating plate, and the flange is rotatably connected to the spacer ring.

[0013] The effect achieved by the above components is that the flange can support the rotating plate, thereby ensuring that the rotating plate rotates stably within the spacer ring.

[0014] Preferably, a spiral plate is fixedly mounted on the circumferential surface of the rotating shaft, and the spiral plate abuts against the inner wall of the discharge pipe.

[0015] The effect achieved by the above components is that after the raw material enters the connecting pipe, the spiral plate will drive the raw material to move downward and enter the relay frame.

[0016] Preferably, the vertical cross-section of the connecting ring is trapezoidal.

[0017] The effect achieved by the above components is that, since the vertical cross-section of the connecting ring is trapezoidal, the gypsum powder raw material will not be squeezed against the inner wall of the connecting ring during the discharge process, thereby reducing the adhesion of the raw material.

[0018] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0019] 1. In this utility model, by setting up components such as partitions, partition rings, connecting rings, arch-breaking rods and rotating plates, the arch-breaking rods can break up the raw materials when feeding other equipment during the production of building gypsum powder, thereby facilitating the subsequent conveying of the raw materials and improving the practicality of the screw conveyor.

[0020] 2. In this utility model, by setting a connecting ring with a trapezoidal vertical cross-section, the gypsum powder raw material will not be squeezed against the inner wall of the connecting ring during the discharge process, thereby reducing the adhesion of the raw material.

Detailed Implementation

[0027] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0028] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0029] like Figures 1-5As shown, this utility model provides a feeding device for producing building gypsum powder, including a base 1. A hopper 2 and a relay frame 3 are fixedly mounted on the upper surface of the base 1. A connecting pipe 8 is fixedly connected to the lower end of the hopper 2 and the upper surface of the relay frame 3. A conveying pipe 4 is fixedly connected to the side wall of the relay frame 3. A discharge pipe 5 is fixedly connected to the circumferential surface of the conveying pipe 4. An auger 6 is rotatably connected to the inner wall of the relay frame 3 and abuts against the inner wall of the conveying pipe. A feed pipe 9 is fixedly connected to the side wall of the hopper 2. A partition 10 and a spacer ring 11 are fixedly mounted on the inner wall of the hopper 2. The inner wall of the spacer ring 11 rotates... The screw conveyor is connected to a rotating plate 13. A connecting ring 12 is fixedly assembled between the partition plate 10 and the partition ring 11. A rotating shaft 16 is rotatably connected to the inner wall of the hopper 2. The rotating shaft 16 is fixedly connected to the rotating plate 13. Several anti-arch rods 17 are fixedly assembled on the upper surface of the rotating plate 13. By setting up components such as the partition plate 10, partition ring 11, connecting ring 12, anti-arch rods 17 and rotating plate 13, during the production of building gypsum powder, when it is necessary to feed other equipment, the anti-arch rods 17 can break up the raw materials, thereby facilitating the subsequent conveying of the raw materials and improving the practicality of the screw conveyor.

[0030] A sealing plate 14 is fixedly installed on the inner wall of the hopper 2. The sealing plate 14 abuts against the lower surface of the rotating plate 13. Both the sealing plate 14 and the rotating plate 13 have material discharge holes on their surfaces. When the material discharge holes on the surfaces of the rotating plate 13 and the sealing plate 14 are misaligned, the raw material will accumulate in the space formed by the rotating plate 13, the connecting ring 12, and the partition plate 10. A support plate 20 is fixedly installed on the circumferential surface of the rotating shaft 16. A scraper 21 is fixedly installed on the surface of the support plate 20. The scraper 21 abuts against the inner circumferential surface of the connecting ring 12. When the support plate 20 rotates with the rotating shaft 16, it will drive the scraper 21 to slide along the inner circumferential surface of the connecting ring 12. The scraper 21 can scrape off the residual gypsum powder raw material to ensure... The material is discharged cleanly. A flange 18 is fixedly mounted on the outer circumference of the rotating plate 13. The flange 18 is rotatably connected to the spacer ring 11. The flange 18 can support the rotating plate 13, thereby ensuring that the rotating plate 13 rotates stably within the spacer ring 11. A spiral plate 19 is fixedly mounted on the circumference of the rotating shaft 16. The spiral plate 19 abuts against the inner wall of the discharge pipe 5. After the raw material enters the connecting pipe 8, the spiral plate 19 will drive the raw material to move downward and enter the relay frame 3. The vertical cross section of the connecting ring 12 is trapezoidal. Because the vertical cross section of the connecting ring 12 is trapezoidal, the gypsum powder raw material will not be squeezed against the inner wall of the connecting ring 12 during the discharge process, thereby reducing the adhesion of the raw material.

[0031] The overall working principle is as follows: During the production of building gypsum powder, the gypsum powder raw material is discharged into the hopper 2 through the feed pipe 9. When the discharge holes on the surface of the rotating plate 13 and the sealing plate 14 are misaligned, the raw material will accumulate in the space formed by the rotating plate 13, the connecting ring 12, and the partition plate 10. When it is necessary to feed other equipment, the first motor 7 and the second motor 15 are turned on. The first motor 7 will drive the auger 6 to rotate, and the second motor 15 will drive the rotating shaft 16 to rotate. The rotating shaft 16 will drive the rotating plate 13 to rotate. At this time, the discharge holes on the surface of the rotating plate 13 and the sealing plate 14 will gradually align, and the raw material will enter the connecting pipe 8 through the discharge holes. During this process, the rotating plate 13 will drive the anti-arch rod 17 to rotate. The anti-arch rod 17 can break up the raw material, thereby facilitating the normal passage of the raw material through the discharge hole. The flange 18 supports the rotating plate 13, ensuring that the rotating plate 13 rotates stably within the spacer ring 11. The support plate 20 rotates with the rotating shaft 16, causing the scraper 21 to slide along the inner circumference of the connecting ring 12. The scraper 21 can scrape off the residual gypsum powder material, ensuring clean discharge. At the same time, since the vertical cross-section of the connecting ring 12 is trapezoidal, the gypsum powder material will not be squeezed against the inner wall of the connecting ring 12 during the discharge process, thereby reducing the adhesion of the material. After the material enters the connecting pipe 8, the spiral plate 19 will drive the material to move downward and enter the relay frame 3. At this time, the auger 6 will contact the material and discharge the material into the conveying pipe 4. Afterward, the material will be discharged through the discharge pipe 5, thereby realizing the feeding of other equipment and facilitating the production of gypsum powder.

[0032] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
