Description

Technical Field

[0001] This utility model relates to the field of fluidized bed technology, specifically to a clogging-resistant fluidized bed drying device. Background Technology

[0002] Fluidized bed dryer is a new type of high-efficiency fluidized bed drying equipment suitable for drying granular and powdery materials. Its working method is as follows: the material enters the equipment from the feed inlet. Under the action of vibration, the material is thrown forward continuously in the horizontal direction. The hot air in the drying air box passes through the distribution plate of the fluidized bed and exchanges heat with the wet material. After the humid air is dusted by the cyclone separator, it is discharged from the exhaust port. The dried material is discharged from the discharge port.

[0003] Existing fluidized beds still have some shortcomings in use. Some materials that become more viscous after being heated are prone to sticking or clumping, causing sieve plate blockage, which in turn reduces the gas throughput, thus affecting drying efficiency and making cleaning difficult.

[0004] To solve the above problems, a vibrating fluidized bed drying device disclosed in the prior art (application number: CN202420335096.6, publication date: 2024-09-20) can be referred to. As the rollers roll, multiple rows of spaced shovels scoop the agglomerated lumps in multiple stages and positions, thereby achieving the cleaning of agglomerated lumps while also dispersing and crushing them. This avoids clogging of the vibrating screen plate and improves the drying efficiency of the material.

[0005] Although the above-mentioned device can solve the purpose of preventing blockage during use, there are still some problems during operation. For example, during vibration, some material will leak through the inlet and outlet, causing material to fall and making the collection process inconvenient.

[0006] Therefore, we proposed that anti-clogging fluidized bed drying equipment can effectively solve the above problems. Utility Model Content

[0007] The purpose of this invention is to provide a clog-resistant fluidized bed drying device to solve the problem mentioned in the background art where some material leaks through the inlet and outlet positions during vibration of the fluidized bed on the market, resulting in material falling and causing inconvenience in collection.

[0008] To achieve the above objectives, the present invention provides the following technical solution: a clog-resistant fluidized bed drying device, comprising a support frame, a fluidized bed body installed at the upper end of the support frame, an inlet and an outlet respectively opened at the left and right ends of the fluidized bed body, an air outlet opened at the top of the fluidized bed body, and an air pump for conveying drying gas installed at the bottom of the support frame.

[0009] The output end of the gas pump is connected to the bottom of the jet assembly via a hose. A locking mechanism is provided on the outside of the support frame. The locking mechanism allows the fluidized bed body to rotate in different directions at the top of the support frame to facilitate feeding and discharging.

[0010] Two sets of electric push rods are also fixedly installed at the bottom of the fluidized bed body. The output end of the electric push rod is connected to the closing mechanism. The two sets of closing mechanisms can realize the independent closing and opening of the closing plates rotated on the outside of the inlet and outlet of the fluidized bed body.

[0011] A drying plate is slidably installed inside the support frame. An anti-clogging mechanism is installed at the bottom of the drying plate. The anti-clogging mechanism allows the drying plate to shake up and down, which can prevent the material on the top of the drying plate from clogging.

[0012] As a preferred technical solution of this application, the locking mechanism includes a foot pedal that is slidably disposed on the outside of the support frame. The outside of the foot pedal is connected to the outer wall of the support frame through a return spring. The top of the foot pedal is engaged in a slot opened on the outer edge of the chuck to achieve the purpose of locking the chuck. A turntable is also fixed at the outer end of the chuck. One end of the chuck is fixed at the outer side of the fluidized bed body.

[0013] As a preferred technical solution of this application, the slot is opened at an angle relative to the center position of the chuck, and the top of the foot pedal forms an engaging structure with the chuck through the slot, and the rotation range of the fluidized bed body is -45 degrees to 45 degrees.

[0014] As a preferred technical solution of this application, the closing mechanism includes a receiving plate fixed at the bottom of the electric push rod, and a connecting shaft is rotatably connected to the top of the receiving plate. The top protrusion of the connecting shaft is slidably disposed on the inner wall of the slide groove. The slide groove is opened at the bottom of the closing plate, and the bottom side of the closing plate is rotatably disposed on the left and right sides of the support frame.

[0015] As a preferred technical solution of this application, the closing plate forms a rotating structure with the left and right ends of the support frame via a connecting shaft, and the outer side of the closing plate is fitted to the side wall groove of the support frame.

[0016] As a preferred technical solution of this application, the anti-clogging mechanism includes a drive rod rotatably disposed inside the support frame, and a cam is fixed on the outer side of the drive rod. The top of the cam is attached to the bottom of the drying plate. The corner of the drying plate is slidably disposed on the outer side of the guide rod. The bottom of the guide rod is connected to one end of a connecting spring. The bottom of the connecting spring is fixed inside the support frame.

[0017] As a preferred technical solution of this application, the drying plate forms a sliding structure between the cam and the outer side of the guide rod, and the drying plate is located directly above the jet assembly.

[0018] Compared with the prior art, the beneficial effects of this utility model are as follows: This anti-clogging fluidized bed drying equipment is equipped with a locking mechanism. The locking mechanism facilitates the loading and unloading of materials at the inlet and outlet of the fluidized bed body. In addition, the closing mechanism prevents leakage during the drying process, and the anti-clogging mechanism ensures that no residue remains on the top of the drying plate. The specific details are as follows:

[0019] 1. A foot pedal is provided. By separating and engaging the foot pedal with the slot, the turntable can be switched between rotating and engaging states, allowing the fluidized bed body to rotate in different directions, which facilitates subsequent feeding and discharging processes.

[0020] Furthermore, an electric push rod is installed, which allows the receiving plate to be positioned below the fluidized bed body. Additionally, the connecting shaft allows the chute to slide inside the closure plate, enabling the closure plate to close and open on the side wall of the fluidized bed body. After closing, this effectively prevents material leakage.

[0021] 2. A cam is provided. The rotation of the cam allows the bottom of the drying plate to slide on the outside of the guide rod, which in turn allows the drying plate to shake up and down via the connecting spring. This shakes the material at the top of the drying plate, thus preventing blockage.

[0022] Furthermore, a drying plate is installed directly above the air pump to ensure that the material at the top of the drying plate is fully dried. Attached Figure Description

Detailed Implementation

[0030] 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.

[0031] Please see Figures 1-6 The present invention provides the following technical solution:

[0032] Example 1: To facilitate the loading and unloading of materials inside the fluidized bed body 2, please refer to the attached document. Figure 1 - Appendix Figure 3A fluidized bed body 2 is installed at the upper end of the support frame 1. Inlet and outlet are respectively located at the left and right ends of the fluidized bed body 2. An air outlet 3 is also located at the top of the fluidized bed body 2. A gas pump 4 for conveying dry gas is installed at the bottom of the support frame 1. The output end of the gas pump 4 is connected to the bottom of the jet assembly 5 via a hose. A locking mechanism is provided on the outside of the support frame 1. This locking mechanism allows the fluidized bed body 2 to rotate in different directions at the top of the support frame 1, facilitating feeding and discharging. The locking mechanism includes a support... A foot pedal 6 is slidably mounted on the outer side of the support frame 1. The outer side of the foot pedal 6 is connected to the outer wall of the support frame 1 through a return spring 7. The top of the foot pedal 6 is engaged in a slot 9 opened on the outer edge of the chuck 8 to achieve the purpose of locking the chuck 8. A turntable 10 is also fixed at the outer end of the chuck 8. One end of the chuck 8 is fixed on the outer side of the fluidized bed body 2. The slot 9 is opened at an equal angle with respect to the center of the chuck 8, and the top of the foot pedal 6 forms an engaging structure with the chuck 8 through the slot 9. The rotation range of the fluidized bed body 2 is -45 degrees to 45 degrees.

[0033] First, after a certain amount of material is added to the inside of the fluidized bed body 2, and the inlet and outlet positions of the fluidized bed body 2 are closed, the bottom position of the foot pedal 6 is stepped on, which allows the foot pedal 6 to slide on the outside of the support frame 1 via the return spring 7. This allows the top position of the foot pedal 6 to disengage from the slot 9 opened in the chuck 8. At this time, the turntable 10 can be rotated, which can drive the chuck 8 to rotate, causing the turntable 10, chuck 8 and fluidized bed body 2 to rotate. This allows the material inside the fluidized bed body 2 to be leveled, so that the material inside the fluidized bed body 2 can be fully filled on the inside of the drying plate 16, which is convenient for subsequent drying. In addition, when discharging material, a set of closing mechanisms is opened to make the fluidized bed body 2 tilt downwards, which facilitates the material discharge process.

[0034] Example 2: To address the issue of material leakage at the inlet and outlet points during vibration in current fluidized beds, leading to material falling and inconvenient collection, please refer to the attached... Figure 1 Appendix Figure 2 and attached Figure 4 - Appendix Figure 6Two sets of electric push rods 11 are fixedly installed at the bottom of the fluidized bed body 2. The output end of the electric push rod 11 is connected to the closing mechanism. The two sets of closing mechanisms can realize the independent closing and opening of the closing plate 15 rotatably set on the outside of the inlet and outlet of the fluidized bed body 2. The closing mechanism includes a receiving plate 12 fixed at the bottom of the electric push rod 11. The top of the receiving plate 12 is rotatably connected to a connecting shaft 13. The top protrusion of the connecting shaft 13 is slidably set on the inner wall of the slide groove 14. The slide groove 14 is opened at the bottom of the closing plate 15. The bottom side of the closing plate 15 is rotatably set on the left and right sides of the support frame 1. The closing plate 15 forms a rotating structure with the left and right ends of the support frame 1 through the connecting shaft 13. The outer side of the closing plate 15 is fitted with the side wall groove of the support frame 1.

[0035] By activating the electric push rod 11, the output end of the electric push rod 11 can drive the receiving plate 12 to adjust its position, and the receiving plate 12 can drive the connecting shaft 13 to change its position, so that the connecting shaft 13 can slide inside the slide groove 14. During the sliding process, the closing plate 15 can rotate at the side wall of the fluidized bed body 2, thereby realizing the closing and opening of the inlet and outlet of the fluidized bed body 2. When opening, it is convenient for material feeding, and during the closing process, leakage is prevented during the drying process.

[0036] Example 3: To address the issue of material blockage inside the fluidized bed body 2, please refer to the attached document. Figure 4 - Appendix Figure 6 A drying plate 16 is slidably disposed inside the support frame 1. An anti-clogging mechanism is provided at the bottom of the drying plate 16. The anti-clogging mechanism enables the drying plate 16 to vibrate up and down, thereby preventing the material on the top of the drying plate 16 from clogging. The anti-clogging mechanism includes a drive rod 19 rotatably disposed inside the support frame 1. A cam 20 is fixed to the outer side of the drive rod 19. The top of the cam 20 is attached to the bottom of the drying plate 16. The corner of the drying plate 16 is slidably disposed on the outer side of a guide rod 17. The bottom of the guide rod 17 is connected to one end of a connecting spring 18. The bottom of the connecting spring 18 is fixed inside the support frame 1. The drying plate 16 forms a sliding structure between the cam 20 and the outer side of the guide rod 17, and the drying plate 16 is located directly above the jet assembly 5.

[0037] By rotating the drive rod 19, the drive rod 19 rotates inside the fluidized bed body 2, causing the cam 20 fixed on the outside of the drive rod 19 to press the bottom of the drying plate 16. This allows the drying plate 16 to slide stably through the guide rod 17, and the guide rod 17 slides elastically through the connecting spring 18. Through the above settings, the material placed on the top of the drying plate 16 can be prevented from clogging.

[0038] The contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0039] 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.
