Description

Technical Field

[0001] The utility model relates to the field of hoppers of fluidized bed dryers, and particularly relates to a hopper of a fluidized bed dryer. Background Technique

[0002] A fluidized bed dryer is a device for efficiently drying solid particles or powders. Its working principle is to create a strong boiling state inside the machine, that is, to use hot air or hot gas to make the material particles present a boiling-like state in the fluidized bed to achieve a fast and uniform drying effect.

[0003] However, in practical applications, especially when there are multiple layers of filter screens distributed in the hopper and the upper layer of filter screen is far from the wall vibrator of the bin, the existing method of realizing the vibration of the layer filter screen through the wall vibrator of the bin has significant deficiencies.

[0004] First of all, when the vibration wave generated by the wall vibrator is transmitted to the upper layer of filter screen, due to the increase in distance, the influence of the material, and the damping effect of the layer filter screen itself, its intensity will be significantly weakened. This results in the vibration effect of the upper layer of filter screen being far inferior to that of the lower layer of filter screen.

[0005] Secondly, the main function of the layer filter screen in the fluidized bed dryer is to ensure the uniform screening of the particle size of the material to ensure the consistency of the drying effect. If the vibration effect of the upper layer of filter screen is insufficient, the fluidity of the material on it will be restricted, and blockage or accumulation is likely to occur. This will not only reduce the screening efficiency, but may also have a negative impact on the efficiency and quality of the entire drying process.

[0006] Furthermore, due to the obstruction of the material fluidity, caking or blockage is likely to form on the layer filter screen. This not only requires the operator to stop the machine regularly for cleaning, but also accelerates the damage of the layer filter screen, resulting in an increased replacement frequency, thereby increasing the maintenance cost of the equipment. Content of the Utility Model

[0007] The main purpose of the utility model is to provide a hopper of a fluidized bed dryer, which can effectively solve the problems put forward in the background technique.

[0008] To achieve the above purpose, the technical solution adopted by the utility model is as follows:

[0009] A hopper of a fluidized bed dryer includes a support seat, a drying fan, a drying box, a connecting pipe, a base, a layered hopper, a wall vibrator, and a vibration connecting cylinder. The drying fan and the drying box are installed on the support seat, and the drying fan blows air into the drying box to dry the material. The base is located beside the support seat, the vibration connecting cylinder is installed on the base and is communicated with the drying box through the connecting pipe. The layered hopper is installed at the upper end of the vibration connecting cylinder, and the wall vibrator is installed on the layered hopper;

[0010] A sealing cover is installed at the upper end of the stratified hopper, and a maintenance cover is installed at the end opening of the sealing cover. A first layer of filter screen and a second layer of filter screen are arranged in the stratified hopper;

[0011] The inner end of the maintenance cover is connected with a spiral vibration pipe, and the lower end of the spiral vibration pipe is provided with an arc-shaped bent pipe, and the arc-shaped bent pipe is connected to the warehouse wall vibrator through a vibration rod.

[0012] In a further preferred embodiment, the spiral vibration tube is of spiral design, the diameter of the spiral vibration tube increases from top to bottom, and the spiral vibration tube is fixed to the maintenance cover by bolts;

[0013] In a further preferred embodiment, the spiral vibration tube and the arc-shaped curved tube are designed as one body, and the arc-shaped curved tube is designed in a "丿" shape, and the arc-shaped curved tube passes through the opening at the end of the vibration rod;

[0014] In a further preferred embodiment, the vibrating rod is fixed to the stratified hopper aligned with the silo wall vibrator by bolts, and the vibrating rod is a rigid rod, which vibrates the stratified hopper through the silo wall vibrator, thereby intensifying the vibration of the spiral vibrating tube, the first layer filter screen and the second layer filter screen;

[0015] In a further preferred embodiment, the spiral vibration tube passes through the first filter screen layer and the second filter screen layer and extends to the central axis of the vibration connection cylinder. The first filter screen layer and the second filter screen layer are fixed to the layered hopper through a ring and bolts, and a buffer rubber ring is provided between the first filter screen layer and the second filter screen layer and the ring.

[0016] In a further preferred embodiment, a feed pipe is provided at the upper end of the sealing cover, and materials enter through the feed pipe. A protective mesh cover is installed on the support seat, and the drying box is covered with the protective mesh cover.

[0017] Compared with the prior art, the utility model has the following beneficial effects:

[0018] In the utility model, the vibration rod, as a typical rigid structure, plays a vital role in the entire vibration transmission system. It can accurately and efficiently transmit the subtle and strong vibrations generated by the warehouse wall vibrator to the spiral vibration tube closely connected to it. This vibration transmission method not only ensures the maximum utilization of energy, but also ensures the stability and reliability of the vibration effect.

[0019] The design of the spiral vibration tube is ingenious. Its spiral shape and gradually increasing diameter design make the vibration show more complex and intense characteristics during the transmission process. This design not only enhances the intensity of the vibration but also enables the material in the stratified hopper to be vibrated and stirred more comprehensively and deeply. Under this vibration effect, the material can be stirred and dispersed more evenly, thereby improving the efficiency and effect of the entire treatment process.

[0020] The contact between the spiral vibration tube and the first-layer filter screen and the second-layer filter screen not only realizes the transmission of vibration but also cleverly plays its auxiliary function. When the vibration is transmitted to the filter screen through the spiral vibration tube, the material on the screen will be subjected to more frequent vibration impacts. This vibration impact can effectively prevent the material from accumulating and blocking on the screen, keeping the screen always in an unobstructed state. At the same time, this vibration also helps the material to be evenly distributed and stratified on the screen, further improving the screening efficiency and accuracy of the screen.

[0021] The combined use of the bin wall vibrator and the spiral vibration tube enables the material in the entire stratified hopper to be fully vibrated and stirred. Under this vibration effect, the material can flow and distribute more smoothly, avoiding the accumulation and caking of the material in the hopper. This not only provides good conditions for the subsequent drying treatment but also ensures the uniformity and consistency of the drying effect. During the drying treatment process, the material can be evenly subjected to the action of heat, thus avoiding the phenomenon of local overheating or overcooling and ensuring the quality and stability of the product.

[0022] The vibration rod and the spiral vibration tube play a crucial role in the stratified hopper vibration system. Through efficient and stable vibration transmission and unique structural design, they achieve the full vibration and stirring of the material in the stratified hopper, providing good conditions for the subsequent drying treatment and ensuring the quality and stability of the product.

DETAILED DESCRIPTION

[0028] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0029] like Figures 1 to 4 As shown, a well-designed boiling dryer hopper is mainly composed of the following key parts: a support base 1, a drying fan 2, a drying box 3, a connecting pipe 5, a base 6, a layered hopper 7, a bin wall vibrator 8, a vibration connecting tube 9, etc.

[0030] The drying fan 2 and the drying box 3 are firmly mounted on the support base 1. The main function of the drying fan 2 is to introduce the wind into the drying box 3 by blowing air to achieve the drying effect of the material. At the same time, the base 6 is placed next to the support base 1, and the vibration connecting tube 9 is installed on the base 6 and is closely connected to the drying box 3 through the connecting pipe 5 to ensure the smooth transmission of the material between the two.

[0031] At the upper end of the vibrating connecting cylinder 9, we installed a stratified hopper 7. The design of this hopper is unique, not only in its stratification function, but also in the installation of a silo wall vibrator 8 on it to ensure the uniform distribution and smooth flow of materials in the hopper.

[0032] The upper end of the stratified hopper 7 is equipped with a sealing cover 10, which not only ensures the sealing of the hopper, but also has a maintenance cover 12 installed on its end surface to facilitate future repair and maintenance. Inside the stratified hopper 7, we specially set a first layer of filter screen 13 and a second layer of filter screen 14 for screening and separating materials.

[0033] In order to further enhance the vibration effect, a spiral vibration tube 16 is connected to the inner end of the maintenance cover 12. The vibration tube has a unique design, is spiral-shaped, and its diameter gradually increases from top to bottom. The spiral vibration tube 16 is fixed to the maintenance cover 12 by bolts to ensure its stability.

[0034] The spiral vibrating tube 16 and the arc-shaped curved tube 17 are designed as one body. The arc-shaped curved tube 17 is in the shape of a Chinese character "丿", passes through the opening at the end of the vibrating rod 15, and forms a stable connection with the vibrating rod 15. The vibrating rod 15 is fixed to the stratified hopper 7 aligned with the silo wall vibrator 8 by bolts. It is a rigid rod. When the silo wall vibrator 8 is working, the vibration will be transmitted to the stratified hopper 7, thereby intensifying the vibration of the spiral vibrating tube 16, the first layer of filter screen 13 and the second layer of filter screen 14.

[0035] The spiral vibration tube 16 not only passes through the first filter screen 13 and the second filter screen 14, but also extends to the central axis of the vibration connection cylinder 9. The first filter screen 13 and the second filter screen 14 are fixed to the layer hopper 7 by a ring and bolts, and a buffer rubber ring is provided between them and the ring to reduce the impact of vibration on the layer filter screen.

[0036] At the upper end of the sealing cover 10, we set a feed pipe 11, through which the material can smoothly enter the layering hopper 7. At the same time, we also installed a protective mesh cover 4 on the support base 1, its main function is to cover the drying box 3 and protect it from external influences.

[0037] The working process is as follows: When the material enters the stratification hopper 7, in order to ensure the uniform distribution and smooth flow of the material in the hopper, the silo wall vibrator 8 is started. The vibration generated by the silo wall vibrator 8 is first transmitted to the vibration rod 15 in direct contact with it. As a rigid rod, the vibration rod 15 effectively transmits the vibration to the components connected to it.

[0038] The vibration is transmitted to the spiral vibration tube 16 through the vibration rod 15. The spiral vibration tube 16 can produce a more complex and strong vibration effect due to its unique spiral shape and gradually increasing diameter. The spiral vibration tube 16 not only generates vibration itself, but also transmits the vibration to the layer filter screen through its contact with the first layer filter screen 13 and the second layer filter screen 14. This vibration helps the layer filter screen to screen and separate materials, while preventing materials from accumulating on the layer filter screen.

[0039] The buffer rubber ring arranged between the layer filter screen and the ring can reduce the direct impact of vibration on the layer filter screen, protect the layer filter screen from damage, and extend its service life. Under the joint action of the bin wall vibrator 8 and the spiral vibration tube 16, the material is fully vibrated and stirred in the layered hopper 7, achieving uniform distribution and smooth flow. At the same time, the material is screened by the first layer filter screen 13 and the second layer filter screen 14, achieving separation of different particle sizes.

[0040] The screened materials enter the drying oven 3 through the vibrating connection cylinder 9 and the connecting pipe 5 for subsequent drying treatment. The combined use of the bin wall vibrator 8 and the spiral vibrating pipe 16 not only improves the vibration effect of the layer filter screen, but also ensures the uniform distribution and smooth flow of the materials in the hopper, providing good conditions for the subsequent drying treatment.
