Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of nitrocellulose production equipment, in particular to an automatic water intake mechanism and a nitrocellulose washing device. Background Art
[0002] At present, the conveying and processing of nitrocellulose is mostly pulp conveying and processing. The fine washing process of nitrocellulose is to wash the nitrocellulose pulp with water, let it stand for a period of time after washing, discharge the washing water, and wash the nitrocellulose pulp with water again. The existing graded water intake device is used for water intake, which has the problems of long production time, large material loss, cumbersome operation and easy error. In addition, it needs to be operated in sections for many times, and the automation and continuity are poor, which affects the production efficiency. On the one hand, because the nitrocellulose fiber is light and has a low density, it is difficult to precipitate in water and the precipitation time is long; on the other hand, the precipitation speed is affected by the fineness of the nitrocellulose. The lower the fineness of the nitrocellulose, the faster the precipitation speed, and vice versa.
[0003] The existing water intake method is to manually open the drain valve switch to take water after the slurry has settled for one hour. There are three drainage pipes in total, each of which is separated by a certain distance. The drainage pipes are equipped with separate manual switch valves. When taking water, the valve needs to be opened manually, and the next level of water intake valve is opened when the liquid level drops to the next level of drainage pipe. This method is cumbersome to operate and takes a long time to take water. It is difficult to control and is prone to material loss. It increases production costs, labor intensity, and reduces production efficiency.
[0004] Therefore, there is an urgent need for an automatic water intake mechanism and a nitrocellulose washing device to solve the above problems. Utility Model Content

[0036] like Figure 1 and Figure 2As shown, this embodiment provides an automatic water intake mechanism, which is used for draining water when washing nitrocellulose slurry. The nitrocellulose slurry and washing water are located in a cleaning machine 1. Specifically, the automatic water intake mechanism includes a telescopic tube 2 and a buoyancy assembly 3. The bottom end of the telescopic tube 2 is connected to the drain port at the bottom of the cleaning machine 1 and can be telescoped along the height direction of the cleaning machine 1. A water intake port 20 is provided on the side wall of the telescopic tube 2. The buoyancy assembly 3 includes a float 31 and a float plate 32. The float 31 is connected to the upper end of the telescopic tube 2 and can float on the surface of the washing water. The float plate 32 is connected to the side wall of the telescopic tube 2 and is located below the surface of the washing water. The water intake port 20 is located between the float 31 and the float plate 32, so that the washing water can flow into the telescopic tube 2 and then be discharged. As the water level of the washing water drops, the float plate 32 can float on the liquid surface of the nitrocellulose slurry. When washing nitrocellulose slurry in the cleaning machine 1, during the process of settling the nitrocellulose slurry, the float 31 floats on the surface of the washing water (the dotted line at the top in the figure), so that the water inlet 20 located on the telescopic tube 2 between the float 31 and the floating plate 32 is in the washing water, so that the washing water automatically flows into the telescopic tube 2 from the water inlet 20 and is discharged from the drainage port at the bottom of the cleaning machine 1, achieving drainage while settling, saving cleaning time, improving production efficiency, and no manual drainage, which is conducive to reducing labor intensity and production costs. And as the washing water is discharged, the water level drops until the floating plate 32 touches the liquid surface of the nitrocellulose slurry and floats on the liquid surface (the dotted line at the bottom in the figure), which can prevent the water inlet 20 from contacting the nitrocellulose slurry, thereby avoiding the loss of materials, which is conducive to reducing production costs.
[0037] Specifically, the telescopic tube 2 is a corrugated elastic tube. Washing water enters the telescopic tube 2 through the water inlet 20 and is discharged. The float 31 drops with the water level, and the corrugated elastic tube contracts accordingly, so that the float 31 can drop smoothly and also facilitate the float 31 to rise with the water level; at the same time, the float 31 can also be lifted and the corrugated elastic tube can be stretched for easy cleaning.
[0038] More specifically, a mounting hole is provided on the floating plate 32, and the telescopic tube 2 passes through the mounting hole and is fixedly connected to the floating plate 32. That is, the floating plate 32 is sleeved on the outer periphery of the telescopic tube 2, so that the force between the floating plate 32 and the telescopic tube 2 is relatively uniform, avoiding tilting that affects the drainage stability.
[0039] Preferably, the distance between the water inlet 20 and the bottom of the float 31 is 10mm-150mm, for example, the distance between the water inlet 20 and the bottom of the float 31 is 10mm, 40mm, 80mm, 120mm or 150mm, etc., which is set according to actual needs. The water inlet 20 is close to the water surface, so that the discharged washing water is always the washing water close to the water surface, which can effectively reduce the loss of materials, and at the same time can discharge impurities floating on the water surface, thereby improving product quality.
[0040] In this embodiment, the average density of the float 31, the telescopic tube 2 and the float plate 32 is 0.3 g / cm 3 -0.7g / cm 3 For example, the average density of the float 31, the telescopic tube 2 and the float plate 32 is 0.3 g / cm 3 , 0.5g / cm 3 or 0.7g / cm 3 The average density of the float 31, the telescopic tube 2 and the floating plate 32 is less than the density of water, so that the float 31 can always float on the water surface, ensuring smooth drainage. It should be noted that the density of the float 31, the telescopic tube 2 and the floating plate 32 can be set according to actual needs, so that the floating plate 32 is always located under the water surface, ensuring that the water intake 20 is located under the water surface, and realizing full-process automatic drainage.
[0041] Optionally, the water intake 20 can be provided in multiple numbers, for example, two water intakes 20 are provided, and the two water intakes 20 are symmetrically arranged on the side wall of the telescopic tube 2 to improve the drainage rate.
[0042] Optionally, the water intake 20 is square, round or irregular in shape. For example, the water intake 20 is square, and the size of the square water intake 20 is 80 mm×100 mm. Of course, the shape and size of the water intake 20 are not limited here and are set according to actual needs.
[0043] During drainage, the float 31 descends as the water level drops, the washing water in the upper layer is discharged through the water inlet 20, and the nitrocellulose slurry in the lower layer is precipitated at the same time. In order to match the drainage speed with the nitrocellulose slurry precipitation speed, the drainage rate is controlled by controlling the diameter of the telescopic tube 2. For example, the diameter of the telescopic tube 2 is 100mm-250mm, for example, the diameter of the telescopic tube 2 is 100mm, 200mm or 250mm, etc.; the diameter of the float 31 is 200mm-300mm, for example, the diameter of the float 31 is 200mm, 250mm or 300mm, and the diameter of the float 31 is larger than the diameter of the telescopic tube 2. The working temperature of the float 31 is less than 200°C.
[0044] Furthermore, the automatic water extraction mechanism further includes a guide rod 4, which is extended along the height direction of the cleaning machine 1 and is arranged inside the cleaning machine 1, and is sleeved in the telescopic tube 2, and the floating ball 31 is slidably sealed and sleeved on the guide rod 4. The guide rod 4 provides a guide and support function for the floating ball 31 and the telescopic tube 2, so as to prevent the telescopic tube 2 from tilting and bending during the telescopic process, resulting in unstable drainage. Exemplarily, the upper end of the guide rod 4 is connected to the top of the cleaning machine 1.
[0045] The present embodiment also provides a nitrocellulose washing device, which includes a cleaning machine 1 and the above-mentioned automatic water intake mechanism arranged in the cleaning machine 1. By adopting the above-mentioned automatic water intake mechanism, it is possible to achieve simultaneous sedimentation and drainage when cleaning the nitrocellulose slurry, thereby saving production time and cost and improving production efficiency.
[0046] Preferably, a stirring paddle 5 is further provided in the cleaning machine 1 , and the nitrocellulose slurry and washing water in the cleaning machine 1 are stirred by the stirring paddle 5 to wash the nitrocellulose slurry.
[0047] The nitrocellulose washing device provided in this embodiment can realize automatic water intake, which is beneficial to reducing labor intensity and improving production efficiency. It can also reduce material loss and discharge impurities, reduce production costs and improve product quality.

Those skilled in the art will understand that the present invention is not limited to the specific embodiments described herein, and that various obvious changes, readjustments and substitutions can be made by those skilled in the art without departing from the scope of protection of the present invention. Therefore, although the present invention is described in more detail through the above embodiments, the present invention is not limited to the above embodiments, and may include more other equivalent embodiments without departing from the concept of the present invention, and the scope of the present invention is determined by the scope of the appended claims.
