Description

Technical Field

[0001] This utility model relates to the field of analyzer technology, and in particular to a high-efficiency horizontal analyzer. Background Technology

[0002] As a gas-solid separation device, the separator is widely used in material handling systems in chemical, metallurgical, energy, and pharmaceutical industries. Its core function is to separate fine powder from materials using airflow, thereby improving the purity and quality of the product. With the continuous improvement of environmental standards, energy efficiency, and production process stability requirements in modern industry, the shortcomings of traditional separators in terms of separation efficiency, energy consumption control, and equipment structure have become increasingly apparent. In some application scenarios, the limited installation space at the top of the silo makes it impossible to directly install a traditional vertical separator at the end of the pneumatic conveying system. To achieve efficient powder removal in limited spaces, horizontal separators are often installed at the silo outlet in confined spaces, thus alleviating the space problem to some extent. However, in actual use, horizontal separators also have certain problems. For example, the material and gas in existing horizontal separators do not come into sufficient contact, which directly weakens the airflow's ability to carry and separate fine dust from the material, resulting in low powder removal efficiency and potentially causing some fine dust to remain inside the separator, affecting the quality of the final product. Utility Model Content

[0003] This invention provides a highly efficient horizontal analyzer to solve the above-mentioned problems.

[0004] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0005] A high-efficiency horizontal separator includes a separator body with a hollow material chamber inside. An inlet pipe and an outlet pipe are installed on both sides of the top of the separator body, and an outlet pipe is installed on one side of the bottom of the separator body. All three pipes are connected to the material chamber. An air inlet chamber is fixedly connected to the lower part of the separator body, and an air inlet is provided in the air inlet. Two spaced-apart sieve plates are installed vertically inside the separator body. An air storage chamber is installed below each sieve plate, and both air storage chambers are connected to the air inlet chamber. The two sieve plates divide the material chamber into an upper material chamber and a lower material chamber, which are connected to each other.

[0006] Preferably, the air inlet chamber is located on one side of the lower part of the analyzer body, and the side of the air inlet chamber near the analyzer body has ventilation openings that correspond one-to-one with the two air storage chambers.

[0007] Preferably, the sieve plate located at the upper part of the analyzer body is called the upper sieve plate, the air storage chamber corresponding to the upper sieve plate is called the upper air storage chamber, the other sieve plate is called the lower sieve plate, and the air storage chamber corresponding to the lower sieve plate is called the lower air storage chamber. The upper sieve plate and the lower sieve plate are both inclined, and the high end of the upper sieve plate is close to the feed pipe, and the low end of the lower sieve plate is close to the discharge pipe.

[0008] Preferably, the discharge pipe and the feed pipe are located on the same side of the analyzer body, the top of the lower screen plate is spaced apart from the upper air storage chamber, and the end of the upper screen plate away from the feed pipe is spaced apart from the inner wall of the material chamber.

[0009] Preferably, the upper screen plate includes a plate body, and a guide plate fixedly connected to the top of the plate body at intervals. An airflow channel is opened in the guide plate, one end of the airflow channel passes through the guide plate, and the other end of the airflow channel passes through the plate body.

[0010] Preferably, the end of the airflow channel is located on the side wall of the guide plate, and the airflow channel is arranged in an arc shape.

[0011] Preferably, the structure of the lower screen plate is the same as that of the upper screen plate; the air inlet is located at the end of the air inlet chamber away from the discharge port.

[0012] Preferably, the guide plates on the upper screen plate are arranged in several rows, each row including multiple guide plates spaced apart, and the guide plates in adjacent rows are staggered, and the facade of the guide plates on the upper screen plate is located on the side of the guide plates closer to the feed pipe; the guide plates on the lower screen plate include several rows of symmetrically arranged guide plates, and the facade of the guide plates on the lower screen plate is located on the side of the guide plates away from the discharge pipe.

[0013] Preferably, a downwardly inclined guide plate is fixedly connected below the feed pipe, and a conductive coil is sleeved on the outer side wall of the upper part of the feed pipe. The conductive coil is fixedly connected to the feed pipe through a metal bracket.

[0014] Preferably, the air outlet pipe is horizontally arranged, the material chamber is shaped like a ">", and one end of the top of the material chamber is connected to the feed pipe. The air outlet pipe is horizontally arranged and the end of the air outlet pipe near the feed pipe is closed. A connecting hole connected to the material chamber is opened at the bottom of the end of the air outlet pipe near the feed pipe.

[0015] The beneficial effects of this utility model are as follows: (1) By setting two sieve plates spaced apart in the body of the separator, it is convenient to perform multiple separation processes on the material, thereby improving the efficiency of the separator in processing the material; (2) By setting the air inlet chamber at the bottom of the separator body and connecting the air inlet chamber with the two air storage chambers through two ventilation ports, the airflow in the air inlet chamber can directly enter the air storage chamber, thereby ensuring that the airflow in the two air storage chambers is relatively clean, so that the airflow that processes the material on the two sieve plates is clean airflow without carrying dust, thereby ensuring the airflow processing capacity to a certain extent; (3) By setting the guide plate, it is convenient to slow down the falling speed of the material on the upper and lower sieve plates, which relatively prolongs the contact time between the airflow and the material, thereby improving the dust removal efficiency to a certain extent.

[0025] The present invention will now be further described with reference to the accompanying drawings.

[0026] A high-efficiency horizontal analyzer, such as Figure 1 and Figure 2 As shown, the analyzer includes an analyzer body 1, with a hollow material chamber 16 inside. A feed pipe 2 and an air outlet pipe 3 are installed on both sides of the top of the analyzer body 1, and a discharge pipe 4 is installed on one side of the bottom of the analyzer body 1. The feed pipe 2, air outlet pipe 3, and discharge pipe 4 are all connected to the material chamber 16. An air inlet chamber 5 is fixedly connected to the lower part of the analyzer body 1, and an air inlet 6 is provided on the air inlet chamber 5. Two spaced-apart sieve plates are installed vertically inside the analyzer body 1. An air storage chamber is installed below each sieve plate in the analyzer body 1, and both air storage chambers are connected to the air inlet chamber 5. The two sieve plates divide the material chamber 16 into an upper material chamber and a lower material chamber, which are connected to each other. In operation, the material to be processed enters the material chamber 16 through the feed pipe 2, and falls onto the sieve plate located in the upper material chamber. Air entering the air inlet 6 and then the air in the air inlet 5 enters two air storage chambers. The airflow in the air storage chambers then passes through the sieve holes on the sieve plate from bottom to top, facilitating the washing and rinsing of the material on the sieve plate. The material, after initial dust removal by the airflow, falls onto the sieve plate located in the lower material chamber. Airflow in the air storage chamber below this sieve plate passes through the sieve holes on the sieve plate, further rinsing the material on this sieve plate to improve dust removal efficiency. The dust-removed material is discharged from the analyzer through the discharge pipe 4, while the airflow carrying dust is discharged from the material chamber 16 through the air outlet pipe 3 and enters the subsequent dust treatment system (this is prior art and will not be described further). By setting two spaced sieve plates inside the analyzer body 1, multiple washing processes are facilitated, improving the analyzer's material processing efficiency.

[0027] In another embodiment, such as Figures 1-3 As shown, the air inlet chamber 5 is located on one side of the lower part of the analyzer body 1. The side of the air inlet chamber 5 closest to the analyzer body 1 has ventilation openings 18 that correspond one-to-one with the two air storage chambers. By placing the air inlet chamber 5 at the lower part of the analyzer body 1 and connecting it to the two air storage chambers through the two ventilation openings 18, the airflow in the air inlet chamber 5 directly enters the air storage chambers. This ensures that the airflow in both air storage chambers is relatively clean, resulting in clean airflow that does not carry dust when processing the material on the two sieve plates. This, to a certain extent, guarantees the airflow processing capacity and improves the processing efficiency of the analyzer.

[0028] In another embodiment, such as Figure 1 and Figure 2As shown, the sieve plate located at the upper part of the analyzer body 1 is designated as the upper sieve plate 7, i.e., the sieve plate located in the upper material chamber is the upper sieve plate 7. The air storage chamber corresponding to the upper sieve plate 7 is designated as the upper air storage chamber 8. The other sieve plate is designated as the lower sieve plate 9, i.e., the sieve plate located in the lower material chamber is the lower sieve plate 9. The air storage chamber corresponding to the lower sieve plate 9 is designated as the lower air storage chamber 10. Both the upper sieve plate 7 and the lower sieve plate 9 are inclined, with the high end of the upper sieve plate 7 positioned close to the feed pipe 2, and the low end of the lower sieve plate 9 positioned close to the discharge pipe 4. The inclined arrangement of the upper sieve plate 7 and its high end being close to the feed pipe 2 allows the material entering the upper sieve plate 7 through the feed pipe 2 to fall onto the lower sieve plate 9 under the guidance of the inclined upper sieve plate 7. The inclined lower sieve plate 9 then allows the material to be discharged through the discharge pipe 4 under the guidance of the lower sieve plate 9, thereby improving the material discharge efficiency to a certain extent and reducing the material residue on the sieve plate.

[0029] In another embodiment, such as Figure 1 and Figure 2 As shown, the discharge pipe 4 and the feed pipe 2 are located on the same side of the analyzer body 1. The top of the lower screen plate 9 is spaced apart from the upper air chamber 8. The end of the upper screen plate 7 away from the feed pipe 2 is spaced apart from the inner wall of the material chamber 16. In use, the material falls onto the upper screen plate 7 through the feed pipe 2, and then falls onto the lower screen plate 9 through the gap between the upper screen plate 7 and the material chamber 16. Finally, it falls into the discharge pipe 4 through the lower screen plate 9 for discharge.

[0030] In another embodiment, such as Figure 4 and Figure 5 As shown, the upper screen plate 7 includes a plate body, with guide plates 11 fixedly connected to the top of the plate body at intervals. Airflow channels 12 are formed within the guide plates 11, with one end of the airflow channels 12 penetrating through the guide plates 11 and the other end penetrating through the plate body. The guide plates 11 help to slow down the falling speed of the material on the upper screen plate 7. Simultaneously, airflow travels from the air storage chamber through the airflow channels 12 to the upper screen plate 7, contacting the material on the upper screen plate 7 to achieve a dust removal effect. The slowing down of the material's falling speed by the guide plates 11 relatively prolongs the contact time between the airflow and the material, thus improving the dust removal efficiency to a certain extent.

[0031] In another embodiment, such as Figure 8As shown, the end of the airflow channel 12 is located on the side wall of the guide plate 11, and the airflow channel 12 is arc-shaped. After the material falls onto the upper screen plate 7 through the feed pipe 2, it is decelerated by the guide plate 11. The airflow channel 12 is opened on the side, allowing the airflow to directly contact the material, thus improving the material washing effect. At the same time, in order to ensure the smooth flow of the airflow channel 12, the airflow channel 12 is smaller than the particle size of the material, so as to prevent the material from falling into the air storage chamber through the airflow channel 12. The presence of airflow in the airflow channel 12 reduces the amount of material remaining on the vertical side of the guide plate 11, thereby reducing material residue on the upper screen plate 7 and reducing the occurrence of material blockage in the airflow channel 12.

[0032] In another embodiment, such as Figure 6 and Figure 7 As shown, the structure of the lower screen plate 9 is the same as that of the upper screen plate 7; the air inlet 6 is located at the end of the air inlet chamber 5 away from the discharge port. By setting the lower screen plate 9 and the upper screen plate 7 to have the same structure, that is, the top of the lower screen plate 9 is also provided with a guide plate 11, and the guide plate 11 includes a vertically arranged surface. The airflow channel 12 is located on one side of the surface of the guide plate 11, so as to reduce the flow rate of the material on the lower screen plate 9 through the guide plate 11 and improve the washing effect. However, it should be noted that the structure of the lower screen plate 9 is the same as that of the upper screen plate 7, which means that the upper guide plate 11 of the upper screen plate 7 and the upper guide plate 11 of the lower screen plate 9 have the same structure, but the inclination directions of the upper screen plate 7 and the lower screen plate 9 are not the same.

[0033] In another embodiment, such as Figures 4-7As shown, the guide plates 11 on the upper sieve plate 7 are arranged in several rows, each row including multiple guide plates 11 spaced apart, and adjacent rows of guide plates 11 are staggered. The vertical surfaces of the guide plates 11 on the upper sieve plate 7 are located on the side of the guide plates 11 closest to the feed pipe 2. The guide plates 11 on the lower sieve plate 9 include several rows of symmetrically arranged guide plates 11, and the vertical surfaces of the guide plates 11 on the lower sieve plate 9 are located on the side of the guide plates 11 away from the discharge pipe 4. Since the material first reaches the upper sieve plate 7 after entering the material chamber 16 through the feed pipe 2, the material on the upper sieve plate 7 has a higher dust content. The staggered guide plates 11 can further reduce the flow rate of the material on the upper sieve plate 7, thereby prolonging the contact time between the airflow and the material and improving the efficiency of the washing process. The amount of dust in the material after washing by the upper sieve plate 7 is reduced. Therefore, the material on the lower sieve plate 9 can pass through the lower sieve plate 9 at a relatively fast speed, thereby reducing the washing time to a certain extent. Furthermore, if the material has a high dust content, the two adjacent rows of guide plates 11 on the lower sieve plate 9 can be staggered to ensure the quality of the washing process. The guide plates 11 on the upper sieve plate 7 are positioned close to the feed pipe 2, and the airflow channels 12 are located on this surface. On one hand, this vertical arrangement facilitates extending the material's residence time and reducing its flow rate. On the other hand, the gas in the airflow channels 12 is blown out horizontally, allowing for direct contact with the downward-moving material, ensuring a large contact area between the gas and the material, and improving the quality and efficiency of the washing process.

[0034] In another embodiment, such as Figure 2 As shown, a downwardly inclined guide plate 13 is fixedly connected below the feed pipe 2. The lower end of the guide plate 13 is spaced apart from the side wall of the feed pipe 2. The channel between the feed pipe 2 and the guide plate 13 is the material channel. By adjusting the inclination angle of the guide plate 13, the size of the material channel can be adjusted, thereby adjusting the material feeding speed so that the material on the upper screen plate 7 is spread in a uniform thin layer.

[0035] In another embodiment, such as Figure 1 and Figure 2As shown, a conductive coil 14 is sleeved on the outer wall of the upper part of the feed pipe 2, and the conductive coil 14 is fixedly connected to the feed pipe 2 through a metal bracket 15. During the material conveying process, the surface of the pipe often carries static electricity. When the material comes into contact with the pipe, the surface of the material will also carry static electricity. The material with static electricity will cause micro dust to adhere tightly to the surface of the material particles, thereby affecting the solid-powder separation work and reducing the powder removal efficiency. Therefore, a conductive coil 14 is sleeved on the outer wall of the feed pipe 2. The conductive coil 14 is grounded to ground the charge on the surface of the pipe, reduce the static electricity on the surface of the pipe, and thus reduce the static electricity carried by the material during the collision with the pipe to a certain extent, thereby reducing the impact of static electricity on the subsequent solid-powder separation work. Meanwhile, the conductive coil 14 can also be selected as an electromagnetic coil. The electromagnetic coil can be sleeved on the outer wall of the feed pipe 2 or located in the groove on the inner wall of the feed pipe 2 (the case of being located in the inner wall is not shown in the figure. When it is located in the groove on the inner wall of the feed pipe 2, the electromagnetic coil does not protrude from the inner wall of the feed pipe 2 to ensure smooth feeding). The electromagnetic coil generates an alternating electromagnetic field. In the electromagnetic field, the dynamic electrostatic adsorption phenomenon between material particles and between material particles and dust will be destroyed, thereby reducing the adhesion between dust and material particles. The effect is particularly significant for tiny dust impurities, thus providing the possibility for subsequent solid-powder separation and improving the quality and efficiency of dust removal.

[0036] In another embodiment, such as Figure 1 and Figure 2 As shown, the air outlet pipe 3 is horizontally arranged, and the material chamber 16 is shaped like a ">", with one end of the top of the material chamber 16 connected to the feed pipe 2. The air outlet pipe 3 is horizontally arranged, and the end of the air outlet pipe 3 near the feed pipe 2 is closed. A connecting hole 17 connected to the material chamber 16 is opened at the bottom of the end of the air outlet pipe 3 near the feed pipe 2. With this arrangement, the airflow carrying dust after passing through the lower screen plate 9 and the upper screen plate 7 is guided by the material chamber 16 and enters the air outlet pipe 3 through the connecting hole 17, thereby guiding the airflow carrying dust. The airflow is discharged through the air outlet pipe 3 along a fixed path, avoiding disordered turbulence in the material chamber 16, ensuring sufficient contact between the material and the airflow, avoiding the defect of airflow short circuit, and greatly improving the dust carrying and separation efficiency of the airflow.

[0037] The above embodiments are not intended to limit the shape, material, structure, etc. of this utility model in any way. Any simple modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of this utility model shall fall within the protection scope of this utility model.
