Description

Technical Field

[0001] This utility model belongs to the field of sodium bicarbonate production technology, and in particular relates to a fabric device used in sodium bicarbonate production. Background Technology

[0002] In sodium bicarbonate production, the wet material after centrifugation and dehydration needs further drying to meet product standards. The thickness and uniformity of the material during drying are crucial. If the centrifuge directly feeds the material into the dryer, the feeding speed and material layer thickness are difficult to control, affecting the drying process. This is especially true for sodium bicarbonate; uneven material distribution leading to uneven heating may cause some product to decompose into sodium carbonate, reducing product quality. Furthermore, long-term uneven material distribution accelerates the breakage of the conveyor belt, and broken belt material mixed into the material poses a significant safety hazard. Currently, sodium bicarbonate production suffers from drawbacks such as difficulty in controlling the feeding speed after centrifugation and uneven material thickness, resulting in uneven drying and poor product quality. Designing a material distribution device for sodium bicarbonate production is a pressing technical problem that needs to be solved in this field. Utility Model Content

The utility model will now be described in detail with reference to the accompanying drawings. Example

[0034] A fabric feeding device for sodium bicarbonate production includes a centrifuge feeding structure 1, a vibrating material blocking structure 2, and a conveyor belt structure 3 arranged from top to bottom. The centrifuge feeding structure 1 and the vibrating material blocking structure 2 are inclined in opposite directions. Both the centrifuge feeding structure 1 and the vibrating material blocking structure 2 are equipped with a vibrating structure 4, which is a vibrating pump.

[0035] The centrifuge feeding structure 1 is provided with a trapezoidal, retractable feeding and discharging structure 5 at its bottom;

[0036] The vibrating material blocking structure 2 is provided with a material blocking component 6 for dispersing materials. The material blocking component 6 divides the vibrating material blocking structure 2 into a receiving area and a discharging area. The bottom of the discharging area is provided with a material blocking and discharge structure 7.

[0037] The conveyor belt structure 3 is equipped with a material leveling component for uniformly distributing material thickness.

[0038] In this embodiment, both the centrifuge feeding structure 1 and the vibrating baffle structure 2 are inclined to the horizontal plane, and their inclination directions are opposite. The bottom of the centrifuge feeding structure 1 is provided with a trapezoidal, converging feeding outlet structure 5. The feeding outlet is located at the bottom of the trapezoidal, converging feeding outlet structure. A vibration pump can cause the centrifuge feeding structure 1 to vibrate, which helps the material fall evenly through the feeding outlet. The material falls into the receiving area of ​​the vibrating baffle structure 2. A vibration pump can also cause the vibrating baffle structure 2 to vibrate, which helps the material fall evenly along the inclined surface of the vibrating baffle component. During the falling process, the material will pass through an open area... The open-type material blocking component 6, taking this embodiment as an example, includes a material blocking plate with an inclined "︿" shape. The material blocking plate is 1cm away from the bottom plate of the vibrating material blocking structure, so that the material can easily fall in the middle. The material blocking plate can disperse the material higher than the gap to both ends of the material blocking component, so that the material is more evenly distributed into the feeding area, and the feeding speed of the material after centrifugation can be controlled. The material falls to the conveyor belt structure 3 through the material blocking and discharge structure 7. The conveyor belt structure 3 is equipped with a material equalization brush that can move left and right, which plays a role in adjusting the material distribution and controlling the thickness of the material layer after centrifugation.

[0039] Furthermore, in this embodiment, the centrifuge feeding structure 1, the vibrating material blocking structure 2, and the conveyor belt structure 3 are installed within the overall frame 8. The centrifuge feeding structure 1 is installed within the overall frame 8 via a fixing frame 9, and the vibrating material blocking structure 2 is installed within the overall frame 8 via several sets of strong springs 10. Through the cooperation of the strong springs and the vibration pump, the distribution and falling can be made more uniform.

[0040] Furthermore, in this embodiment, the material discharge structure 5 can be considered as a trapezoidal structure with a tapered bottom, and the bottom of the material discharge structure 5 is provided with a strip-shaped material discharge port.

[0041] Furthermore, in this embodiment, the vibrating material-blocking structure 2 includes a base plate and side plates surrounding the base plate. The material-blocking component 6 includes at least one set of inclined material-blocking plates, which are "︿" shaped plates with their bottoms 1 cm from the base plate. By adjusting the feeding speed and uniformity of the centrifuged material using a vibrating pump, and coordinating with the inclined material-blocking plates within the material-blocking component 6 to disperse the material, further adjustments are made by the material-leveling brush on the conveyor belt, achieving precise control of the material thickness and distribution. This design solves the problems of difficult-to-control feeding speed and uneven material layer, providing a continuous and uniform material input for the drying process.

[0042] Furthermore, in this embodiment, the material blocking plate can be installed on the side plate of the vibrating material blocking structure 2 via a height adjustment frame 11. The height adjustment frame 11 may include, but is not limited to, a height adjustment screw, an adjustment bolt, etc., to adjust the distance between the material blocking plate and the bottom plate.

[0043] Furthermore, in this embodiment, the bottom of the material blocking and discharge structure 7 is provided with a rectangular material blocking and discharge port, and a baffle 12 is provided around the material blocking and discharge port. The material falling from the material blocking and discharge port falls onto the conveyor belt under the obstruction of the baffle.

[0044] Furthermore, in this embodiment, the conveyor belt structure 3 includes a conveyor belt and a conveyor roller for driving the conveyor belt. The conveyor belt is provided with an edge binding fabric and guide strips. The edge binding fabric is a Tevlar fiber woven fabric coated with polytetrafluoroethylene (PTFE), and the guide strips are silicone rubber guide strips. The original edge binding fabric was made of glass fiber woven fabric with a PTFE coating, and the guide strips were also made using a glass fiber woven process. In production practice, it was found that the tensile strength of the materials was insufficient, causing the edge binding fabric and guide strips to break, exposing the glass fibers, and even contaminating the materials. Using Tevlar fiber woven fabric with a PTFE coating instead of the original edge binding material greatly improves the tensile strength; the original guide strips are changed to silicone rubber, extending their lifespan and preventing the contamination of the materials with the belt material.

[0045] Furthermore, in this embodiment, the material leveling component includes a material leveling bracket 13 and a material leveling brush 14. The material leveling bracket 13 is installed within the overall frame 8 via a position adjustment frame 15. The material leveling bracket 13 is equipped with a left-right moving mechanism for driving the material leveling brush 14 to move left and right. The position adjustment frame 15 may include, but is not limited to, corner brackets slidably mounted on the overall frame and bolts for mounting the corner brackets, used to adjust the position and height of the material leveling brush 14. The left-right moving mechanism may include, but is not limited to, a slider, a slide rail, a connecting rod, and a camshaft motor to achieve the left-right swinging of the material leveling brush. Through the cooperation of the vibration pump, the material discharge structure, the material blocking component, the material blocking and discharge structure, and the material leveling component, a uniform material layer can be formed on the conveyor belt, ensuring consistent heat conduction and preventing the decomposition of sodium bicarbonate due to uneven heating. This increases the product purity to over 99%, while simultaneously improving the dryer's heat utilization rate by 25% and equipment capacity by 30%. It combines multiple advantages of energy saving, cost reduction, and quality assurance, and is suitable for the production of various powder materials and the upgrading of existing production lines.

[0046] Working principle: The centrifuge feeding structure 1 is connected to the centrifuge. After the material is centrifuged and dehydrated, it reaches the centrifuge feeding port. The feeding speed and uniformity are adjusted by the vibration pump. Then the material reaches the material blocking component. The material blocking plate is inclinedly set inside the component. The material blocking plate is 1cm away from the bottom plate, so the material can fall in the middle. The material blocking plate can disperse the material above the gap to both ends of the material blocking component, so that the material distribution is more uniform. At the same time, two vibration pumps adjust the material distribution, so that the material falls evenly. The material reaches the conveyor belt from the feeding port. At this time, the material thickness is relatively uniform. After being further adjusted by the left and right swinging of the uniform brush, the material enters the dryer.

[0047] The above embodiments have provided a detailed description of the present invention, but the content described is only a preferred embodiment of the present invention and should not be considered as limiting the scope of the present invention. All equivalent changes and improvements made in accordance with the claims of the present invention should still fall within the patent coverage of the present invention.
