Description

Technical Field

[0001] This utility model relates to fluidized beds, and more particularly to a fluidized bed that facilitates improved dust removal efficiency. Background Technology

[0002] A fluidized bed is a device based on the fluidization phenomenon, where when a fluid passes through a bed of particulate solid materials, if the fluid velocity is high enough, the particulate solid materials will be suspended. It is generally used for dust removal of particulate solid materials such as cross-linked polyethylene insulation or polyvinyl chloride insulation.

[0003] Because the granular solid materials are prone to generating static electricity during the production process, they can attract dust. In addition, the fluidized bed is generally a positive pressure type, and in order to prevent the granular solid materials from flying out during the fluidization process, the air outlet is usually equipped with an overflow cover. This can cause the purification air to swirl at the top of the fluidized bed, making it difficult for the purification air to carry the dust out of the fluidized bed, resulting in low dust removal efficiency. Utility Model Content

[0004] Purpose of the utility model: The purpose of this utility model is to provide a fluidized bed that facilitates improved dust removal efficiency.

[0029] Example 1

[0030] like Figure 1 This embodiment provides a fluidized bed that facilitates improved dust removal efficiency, comprising: a bed body 1, which has an air inlet 11, an air outlet 12, a feed inlet 13, and a discharge outlet 14; an ion generator 2, which is located at the air inlet 11 and / or the feed inlet 13; an overflow cover 3 connected to one side of the air outlet 12, which is located inside the bed body 1; and a negative pressure fan 4 connected to the other side of the air outlet 12.

[0031] Specifically, the bed body 1 is used to contain purified air and granular solid materials such as cross-linked polyethylene insulation material or polyvinyl chloride insulation material; the ion generator 2 is used to generate charged particles (i.e., ions) to facilitate the elimination of static electricity, thereby facilitating the separation of granular solid materials and dust. The ion generator 2 can be of the corona discharge type, ultraviolet type, etc.; the negative pressure fan 4 is used to create a negative pressure inside the bed body 1, that is, the amount of purified air entering through the air inlet 11 is less than the amount of purified air exiting through the air outlet 12, preventing the purified air and dust from swirling at the air outlet 12 of the bed body 1, thus facilitating the separation of granular solid materials and dust. The purified air carries the dust out of the bed body 1, thereby improving the dust removal efficiency. The air inlet 11 is preferably located at the bottom side of the bed body 1, so that the particulate solid materials in the bed body 1 can all boil. The number of air inlets 11 is preferably multiple, and the multiple air inlets 11 are preferably evenly distributed along the bottom side of the bed body 1 to ensure good uniformity of the purified air entering. The air outlet 12 is preferably located on the top surface of the bed body 1. The negative pressure fan 4 can be centrifugal, axial flow, etc. The overflow cover 3 is used to prevent the particulate solid materials from flying out during the boiling process.

[0032] Furthermore, such as Figure 1 It also includes: a feed pipe 5 passing through the feed inlet 13, at least part of which is located inside the bed body 1; and a dispersion hood 6 connected to one end of the feed pipe 5, which is located inside the bed body 1.

[0033] Specifically, the feed pipe 5 facilitates the entry of particulate solid materials into the bed body 1; the dispersion hood 6 facilitates the entry of particulate solid materials into the bed body 1 in a dispersed manner, thereby facilitating the boiling of particulate solid materials under the action of purification air. The dispersion hood 6 is conical in shape, and the small diameter end of the dispersion hood 6 is connected to one end of the feed pipe 5.

[0034] Furthermore, such as Figure 1 The feed pipe 5 includes a first pipe body 51 and a second pipe body 52 that are bent and connected to each other. The first pipe body 51 passes through the feed port 13. The second pipe body 52 and at least part of the first pipe body 51 are located inside the bed body 1. The end of the second pipe body 52 away from the first pipe body 51 is connected to the dispersion hood 6.

[0035] Specifically, both the first tube 51 and the second tube 52 facilitate the entry of particulate solid material into the bed body 1. Due to their mutual bending and connection, it is easy to adjust the transmission direction of the particulate solid material.

[0036] Furthermore, such as Figure 1 The first tube 51 is arranged horizontally, and the second tube 52 is arranged vertically. Specifically, the horizontally arranged first tube 51 facilitates the reception of particulate solid material from the dehydrator; the vertically arranged second tube 52 facilitates the entry of particulate solid material into the bed body 1 along the direction of gravity, while the purified air flows in the opposite direction to gravity, thereby facilitating the boiling of the particulate solid material.

[0037] Furthermore, such as Figure 1 It also includes: a discharge pipe 71 passing through the discharge port 14, at least part of which is located inside the bed body 1; and a regulating valve 72 connected to the discharge pipe 71. Specifically, the discharge pipe 71 facilitates the discharge of granular solid material from the bed body 1; the regulating valve 72 is used to regulate the discharge rate of granular solid material, and the regulating valve 72 can be a butterfly valve, ball valve, etc.

[0038] Furthermore, such as Figure 1 It also includes a discharge hopper 73 located inside the bed body 1, with the small-diameter end of the discharge hopper 73 connected to the discharge pipe 71. Specifically, the discharge hopper 73 is conical, which facilitates the guidance of granular solid materials, thereby allowing the granular solid materials to smoothly enter the discharge pipe 71.

[0039] Furthermore, such as Figure 1 It also includes several level sensors 8 at different heights, with the detection end of each level sensor 8 located inside the bed body 1. Specifically, the level sensors 8 are used to detect the height of the granular solid material inside the bed body 1. Preferably, there are two level sensors 8 at different heights. An alarm can be triggered when the height of the granular solid material is too low or too high. The level sensors 8 can be capacitive, ultrasonic, or other types.

[0040] Furthermore, such as Figure 1 It also includes several legs 9 connected to the bed body 1. Specifically, the legs 9 are used to support the bed body 1.

[0041] The above embodiments only illustrate several implementation methods of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
