Description

Technical Field

[0001] This utility model relates to the field of feeding device technology, and in particular to a caustic soda flake feeding device. Background Technology

[0002] In chemical production, caustic soda (sodium hydroxide) is widely used as a basic raw material in industries such as papermaking, printing and dyeing, and water treatment. Its dissolution process is typically completed in a solvent tank. Traditional caustic soda feeding devices often employ a single-point fixed feeding method, continuously adding caustic soda to the same area of ​​the solvent tank. However, the dissolution of caustic soda releases a large amount of heat, and its strong alkalinity is corrosive to equipment. This design leads to several problems: firstly, localized high solution concentrations cannot dissipate heat in time, easily forming localized high-temperature zones that exacerbate corrosion of the tank and equipment, and may even cause solvent boiling and splashing, threatening operator safety; secondly, untimely mixing of high-concentration solutions with low-concentration areas can also result in low dissolution efficiency. Furthermore, if the solvent tank is large, single-point feeding cannot cover the entire tank space, affecting the uniformity of subsequent reactions and product quality. While using multiple fixed feed inlets simultaneously can alleviate the problem of excessively high local concentrations, the feeding amount at each inlet is difficult to precisely synchronize, potentially leading to fluctuations in solution concentration. Therefore, a new caustic soda feeding device needs to be designed to solve these problems. Utility Model Content

[0003] This utility model provides a caustic soda flake feeding device. Its feeding structure can achieve reciprocating motion in two dimensions under the coordinated driving action of the first driving component and the second driving component, so as to distribute the caustic soda flakes relatively evenly into each area of ​​the solvent tank, thereby avoiding local overheating and uneven concentration.

[0004] The technical problem solved by this utility model is achieved by the following technical solution: This utility model relates to the field of feeding device technology, and in particular to a caustic soda flake feeding device, including a feeding structure and a solvent tank located below the feeding structure. The feeding structure is connected to a gantry structure. The top of the gantry structure is provided with a first driving member that drives the feeding structure to reciprocate along a first direction, and the bottom of the gantry structure is provided with a second driving member that drives the feeding structure to reciprocate along a second direction perpendicular to the first direction. With the cooperation of the first driving member and the second driving member, the feeding structure can perform reciprocating motion in all directions to achieve feeding at different positions in the solvent tank.

[0005] Preferably, the first driving component includes a first motor, a first lead screw at the output end of the first motor, a first guide rod parallel to the first lead screw and fixed to the top of the gantry structure, and a first slider. The first slider is threadedly connected to the first lead screw, and the first guide rod is slidably connected to the first slider.

[0006] Preferably, the second driving component includes a second motor, a second lead screw located at the output end of the second motor, a second guide rod parallel to the second lead screw and fixed to the top of the gantry structure, and a second slider sleeved on the second lead screw and the second guide rod. The second slider is threadedly connected to the second lead screw, and the second guide rod is slidably connected to the second slider.

[0007] Preferably, the feeding structure includes an outer tube of the feeding machine, a motor located on the outer tube of the feeding machine, a rotating shaft located at the output end of the motor, spiral blades located around the rotating shaft, and a feeding hopper and a discharging port located on the outer tube of the feeding machine.

[0008] Preferably, the feeding structure is fixedly connected to the first slider in the first direction at the top of the gantry structure via a hanger rod and is suspended above the solvent tank.

[0009] Preferably, the movement stroke of the feeding structure under the cooperation of the first driving member and the second driving member satisfies the length of the solvent tank in the first direction and the width of the solvent tank in the second direction.

[0010] The beneficial effects of this invention are as follows: Through the coordinated operation of the first and second driving components on the gantry structure, the feeding structure achieves omnidirectional reciprocating motion above the solvent tank, and its stroke can completely cover the length and width of the solvent tank, solving the problem of caustic soda accumulation caused by traditional single-point fixed feeding. Simultaneously, the stable feeding of the screw feeder, combined with the dynamic feeding position, can relatively evenly disperse the caustic soda into various areas of the solvent tank, effectively avoiding excessively high local concentrations and heat accumulation, reducing corrosion of the tank and equipment, and lowering the safety risk of solution boiling and splashing. Furthermore, full-range feeding eliminates the need for multiple fixed feed inlets. Attached Figure Description

[0013] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below with reference to specific illustrations.

[0014] This utility model provides a caustic soda flake feeding device. To enable those skilled in the art to more clearly understand the improvements of this utility model compared to the prior art, the existing caustic soda flake feeding devices are first described. Existing caustic soda flake feeding devices on the market are mainly fixed-point feeding devices. They generally include a feeding structure 1 for adding caustic soda flakes and a solvent tank 2 located below. The feeding structure 1 is installed above the solvent tank 2 via a fixed bracket. The discharge port 106 is always aligned with a fixed area within the solvent tank 2. The caustic soda flakes are continuously transported to this area through a conveying component to complete the feeding process. Since caustic soda needs to be evenly dispersed during dissolution to avoid localized overheating and excessively high concentrations, and solvent tanks 2 of different sizes need to cover the entire tank for feeding, existing fixed-point feeding devices have the following drawbacks: First, the feeding position is fixed, and caustic soda flakes continuously accumulate in the same area, preventing the heat released from localized dissolution from dissipating, forming a high-temperature zone that exacerbates equipment corrosion and may even cause solution splashing; second, the fixed point cannot cover the edge area of ​​large-sized solvent tanks 2, resulting in uneven concentration distribution within the tank and affecting production efficiency. Based on the above problems, this utility model adopts the following technical solution to address them.

[0015] refer to Figures 1-5As shown, this utility model provides a caustic soda flake feeding device. Its improvement over existing technologies mainly lies in achieving the dispersed feeding of the feeding structure 1 across the entire range of the solvent tank 2 through the synergistic driving action of two driving components. This utility model includes a feeding structure 1 and a solvent tank 2 located below it. The feeding structure 1 is connected to a gantry structure 3 (the gantry structure 3 is composed of a first driving component 4 and a second driving component 5). The first driving component 4 is located at the top of the gantry structure 3, driving the feeding structure 1 to reciprocate along a first direction (e.g., the length direction of the solvent tank 2). The second driving component 5 is located at the bottom of the gantry structure 3, driving the feeding structure 1 to reciprocate along a second direction perpendicular to the first direction (e.g., the width direction of the solvent tank 2). Specifically, the first driving component 4 includes a first motor 401, a first lead screw 402, a first guide rod 403, and a first slider 404. The first lead screw 402 is connected to the output end of the first motor 401. The first guide rod 403 is parallel to the first lead screw 402 and fixed to the top of the gantry structure 3. The first slider 404 is threadedly connected to the first lead screw 402 and slidably connected to the first guide rod 403. The motion principle is based on the transmission between the first lead screw 402 and the first slider 404: when the first motor 401 drives the first lead screw 402 to rotate, the helical raceway on the surface of the first lead screw 402 forms a rolling friction pair with the balls in the first slider 404, converting the rotational motion into linear motion; the parallel first guide rod 403 provides precise guidance for the first slider 404, restricts its degrees of freedom, and bears radial force, ensuring that the first slider 404 moves smoothly only along the axial direction of the first lead screw 402. The second driving component 5 is similar in composition to the first driving component 4, including a second motor 501, a second lead screw 502, a second guide rod 503, and a second slider 504. The second lead screw 502 is connected to the output end of the second motor 501. The second guide rod 503 is parallel to the second lead screw 502 and fixed to the bottom of the gantry structure 3. The second slider 504 is sleeved on the second lead screw 502 and the second guide rod 503, threadedly connected to the second lead screw 502 and slidably connected to the second guide rod 503. The second motor 501 drives the lead screw to rotate, causing the overall structure to move along the second direction. The specific motion principle is the same as that of the first driving component 4, and will not be described in detail here. The two components work together to enable the feeding structure 1 to perform two-dimensional reciprocating motion in all directions, realizing feeding at different positions in the solvent tank 2. This avoids the local problems caused by concentrated accumulation of caustic soda flakes and can cover the entire range of solvent tanks 2 of different sizes.

[0016] To enable those skilled in the art to clearly understand the specific implementation of the feeding structure 1 of this utility model, this utility model provides one embodiment. The outer tube 101 of the feeding structure 1 is made of stainless steel. The feed hopper 105 at the top of the outer tube has a bucket-shaped structure to facilitate the smooth entry of caustic soda flakes. A motor 102 is installed on one side of the outer tube, and the output end of the motor is connected to a rotating shaft 103 that passes through the inside of the outer tube. The spiral blades 104 welded around the rotating shaft 103 have a full-surface design and the gap between them and the inner wall of the outer tube is controlled at 1-2 mm. A discharge port 106 is opened at the bottom of the outer tube. During operation, the motor 102 drives the rotating shaft 103 to rotate the spiral blades 104. After the caustic soda flakes enter from the feed hopper 105, they are continuously pushed to the discharge port 106 by the spiral blades 104, avoiding jamming or accumulation. This design can achieve continuous and stable feeding, and is especially suitable for conveying caustic soda flakes with low moisture content. Of course, the above is only one embodiment of this utility model, and other structural forms can also be adopted. The specific choice can be made according to actual production and living needs.

[0017] Furthermore, to prevent the feeding structure 1 of this utility model from swaying during reciprocating motion (since the feeding structure 1 needs to move frequently under the drive of the first driving member 4 and the second driving member 5, unstable connection methods can easily lead to feeding position deviation or equipment vibration), it is fixedly connected to the first slider 404 in the first direction at the top of the gantry structure 3 via a hanger 6. Specifically, the hanger 6 is made of stainless steel, with its upper end fixedly connected to the bottom of the first slider 404 at the top of the gantry via a flange, and its lower end rigidly connected to the feed hopper 105 via a clamp, ensuring a stable and secure connection. A triangular reinforcing rib is added to the middle of the hanger 6, forming a triangular support structure with the hanger 6 and the outer tube 101 of the feeding machine, improving overall rigidity. This allows the feeding structure 1 to remain stable in the suspended state, avoiding feeding position deviation caused by swaying. Of course, the above is only provided as a reference idea and is not a rigid requirement.

[0018] Furthermore, to ensure that the feeding structure 1 of this invention can cover the entire area of ​​the solvent tank 2 for feeding, the invention further optimizes the motion stroke: Under the cooperation of the first driving member 4 and the second driving member 5, the motion stroke of the feeding structure 1 meets the length of the solvent tank 2 in the first direction and the width of the solvent tank 2 in the second direction (of course, it can also meet the width of the solvent tank 2 in the first direction and the length of the solvent tank 2 in the second direction, as long as the motion in the two directions can cover the length and width of the solvent tank 2 respectively). This allows the feeding point to cover the entire planar area of ​​the solvent tank 2, enabling the caustic soda flakes to be relatively evenly distributed in the solvent tank 2 and improving the consistency of the solution concentration.

[0019] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above-described embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
