Description

Technical Field

[0001] This utility model belongs to the field of linear vibrating screen technology, specifically relating to a linear vibrating screen feeding and dispersing device. Background Technology

[0002] In a linear vibrating screen, material enters from one end and is screened by the vibrating motor as it is propelled forward and upward. The screened material exits from the other end, thus completing the screening process.

[0003] Linear vibrating screens are an important component of the slag removal system in the calcium carbonate production process. They are mainly used in the pulping and carbonation units of the calcium carbonate industry. The operating status of this equipment directly affects key indicators such as calcium carbonate screen residue, whiteness, and hydrochloric acid insoluble matter, thereby affecting the output and quality of the product.

[0004] Currently, in existing linear vibrating screens, the feed slurry flows directly onto the screening belt through the feed pipe during the feeding process. At this point, the calcium carbonate slurry concentrates at the front end of the screening belt, where the impact is greater, leading to easy clogging or damage to the screen mesh. This necessitates frequent screen replacements, affecting the continuous and stable operation of the production equipment. Furthermore, this phenomenon directly results in uneven screening across the entire linear vibrating screen, leading to low screening efficiency.

[0005] In view of this, it is indeed necessary to provide a linear vibrating screen feeding and dispersing device that can solve the above problems. Utility Model Content

[0006] The purpose of this utility model is to overcome the defects of the prior art and provide a linear vibrating screen feeding and dispersing device that can reduce screen clogging and damage, reduce screen replacement frequency, and enable continuous and stable operation of production equipment.

[0007] To achieve the above objectives, this utility model provides a linear vibrating screen feeding and dispersing device, including a distributor and a feed pipe connected to the distributor. The distributor has a discharge port at its bottom and a cleaning port on its side. The discharge port has an umbrella-shaped liquid disperser at its bottom. The liquid disperser is welded and fixed to the bottom of the discharge port by steel or iron bars. The flared end of the liquid disperser is away from the end face of the discharge port and forms a gap with the end face of the discharge port.

[0008] Furthermore, the steel or iron bar is in the shape of a straight line, a cross, an X, or a Y.

[0009] Furthermore, there are at least four discharge ports, evenly distributed at both ends of the bottom of the distributor.

[0010] Furthermore, the diameter of the dispenser is equal to the diameter of the cleaning port.

[0011] Furthermore, the distributor is connected to the feed pipe via a flange.

[0012] Furthermore, a pressure gauge is provided on the feed pipe.

[0013] Compared with the prior art, the linear vibrating screen feeding and dispersing device of this utility model has at least the following advantages:

[0014] 1. By installing a feeding dispersion device above the front end of the vibrating screen mesh, the material is dispersed onto the vibrating screen surface at atmospheric pressure through at least four evenly distributed discharge ports at the bottom of the distributor and an umbrella-shaped liquid disperser. The liquid covers the entire width of the front end of the screen, effectively dispersing the impact force of the material, protecting the vibrating screen surface, reducing equipment wear and the frequency of screen replacement, extending the service life of the equipment, and significantly improving the dispersion effect of the material on the screen surface, increasing the screen filtration efficiency, and enabling the vibrating screen to operate stably at full load.

[0015] 2. By setting a cleaning port on the distributor, when internal cleaning is required, it is only necessary to remove the flange cover or blind plate to remove the feeding and dispersing device from the production system, open the cleaning port to clean the internal accumulated material, making cleaning more efficient and convenient, reducing labor intensity and improving production efficiency.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figure 1 and Figure 2 As shown, this utility model provides a linear vibrating screen feeding and dispersing device, including a distributor 8 and a feed pipe 5 connected to the distributor 8. When removing slag from calcium carbonate slurry, the feeding and dispersing device is installed directly above the front end of the vibrating screen surface 1. The calcium carbonate slurry is distributed across the entire width of the vibrating screen surface 1 through the feeding and dispersing device. The vibrating screen is a commercially available vibrating screen, or it can be a vibrating screen with a modified design according to production needs. The vibrating screen includes a vibrating screen surface 1, a vibrating screen shell 2, a vibrating screen liquid outlet 3, and a vibrating screen slag outlet 4. The distributor 8 is usually a columnar structure, but it can also be a cubic structure, a cuboid structure, a trapezoidal structure, or other shapes depending on the installation space. It has a discharge port 9 at the bottom and a cleaning port 11 on the side. When put into use, the cleaning port 11 is sealed with a flange cover or a blind plate and fixed to the end of the cleaning port 11 with bolts. A liquid disperser 10 is provided at the bottom of the discharge port 9.

[0027] Please see Figure 3 and Figure 4 As shown, the liquid disperser 10 has an umbrella-shaped structure. The top of the liquid disperser 10 is welded and fixed to the bottom of the discharge port 9 by steel or iron bars. The opening of the liquid disperser 10 is far away from the end face of the discharge port 9, which facilitates the dispersion of the material impact force after the material flows from the discharge port 9 to the umbrella surface of the umbrella-shaped liquid disperser 10.

[0028] The feed pipe 5 and the distributor 8 are fixedly connected by a flange 7. In this embodiment of the utility model, the flange 7 is preferably a quick-release flange, which is easy to disassemble and convenient to maintain. A pressure gauge 6 is installed on the feed pipe 5 to control the feed within the normal range.

[0029] In this embodiment of the utility model, four discharge ports 9 are evenly distributed at the bottom of the distributor 8, and a liquid disperser 10 with an umbrella-shaped structure is provided at the bottom of each discharge port 9. The discharge port 9 and the liquid disperser 10 are fixedly connected by welding with a straight steel bar.

[0030] When removing slag from calcium carbonate slurry, the linear vibrating screen feeding and dispersing device of this utility model is installed directly above the front end of the screen surface 1 of the vibrating screen. After the material is dispersed by the umbrella-shaped liquid disperser 10 at the bottom of the discharge port 9, it is evenly distributed on the entire screen surface 1 of the vibrating screen, which increases the material dispersion area and reduces the impact force. The side of the distributor 8 is provided with a cleaning port 11 of the same diameter as the distributor 8, which makes it easier to clean the dispersing device.

[0031] Refer to the instruction manual appendix Figure 1-7 In other embodiments of this utility model, the discharge port 9 and the liquid disperser 10 can be fixedly connected by welding a straight iron bar, or by welding a cross-shaped, X-shaped or Y-shaped steel bar or iron bar.

[0032] In other embodiments of this utility model, the number of discharge ports 9 at the bottom of the distributor 8 can be 5, 6, 7, 8 or even more, and can be evenly distributed at both ends of the bottom of the distributor 8, or the position of the discharge ports 9 can be adjusted as needed.

[0033] Working principle: When removing slag from calcium carbonate products, the linear vibrating screen feeding and dispersing device of this utility model is installed directly above the front end of the vibrating screen surface 1. The slurry enters the distributor 8 through the feed pipe 5. The feed valve (not shown) installed on the feed pipe 5 is adjusted, and the feed is controlled within the normal range by the pressure gauge 6. After the slurry enters the distributor 8, the material passes through the four evenly distributed discharge ports 9 at the bottom of the distributor 8, and the pressure is reduced. Then, it is sprayed onto the umbrella-shaped liquid disperser 10 directly below to continue dispersing the impact force of the material. After the material is distributed in an umbrella shape, it is dispersed onto the vibrating screen surface 1 at normal pressure. The slurry covers the entire width of the front end of the vibrating screen surface 1, with the slurry dispersion area being the largest and the impact force being the smallest. The upper part of the vibrating screen shell 2 is equipped with a baffle. When the slurry falls onto the vibrating screen surface 1, the baffle prevents the slurry from flowing out. After the slurry is separated by the vibration of the vibrating screen mesh 1, solid impurities are discharged from the slag outlet 4 at the rear end of the vibrating screen, and qualified slurry is discharged from the liquid outlet 3 of the vibrating screen to enter the next production unit. When the feeding and dispersing device of the linear vibrating screen needs internal cleaning, the feeding and dispersing device can be removed from the production system by removing flange 7, opening the flange cover or blind plate of cleaning port 11, and cleaning the accumulated material inside distributor 8. This is convenient, efficient, and can achieve a high-efficiency cleaning function.

[0034] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
