[0002] With the development of the times, people are using insulation materials more and more widely. As an important component, hemp fiber requires the use of pickling equipment in the production process to remove internal impurities and demold.

[0003] To this end, patent CN204625794U discloses an acid pickling device, which includes a container (10), a drain pipe (20) for discharging acid, and a set of rollers (30). The container has a plurality of side walls (12) and a base (14), which can enclose a holding space for holding acid. The drain pipe (20) is located at the bottom of the side walls (12) along the depth direction of the container (10). The rollers are located on the ground-facing end face of the base (14). The acid pickling device is easy to move and facilitates acid replacement;

[0004] The pickling device described above requires constant replacement of the acid solution during use, but it is difficult to conveniently filter and recycle the acid solution after pickling, which will result in a large loss of acid solution, making it difficult to meet the actual use requirements. Utility Model Content

[0005] The purpose of this invention is to provide a hemp fiber acid washing device to solve the shortcomings of existing hemp fiber acid washing devices that are not convenient for filtering and recycling the acid washing solution.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a hemp fiber acid washing device, comprising an acid washing body and a support column;

[0007] A support column is fixed at the bottom of the pickling body, and a pickling structure is installed at the bottom of the pickling body.

[0008] The pickling structure includes a collection box installed at the bottom of the pickling body. The top of the collection box has a chute, and a pull-out plate is installed inside the chute. A filter plate is installed inside the pull-out plate. A micro water pump is installed on one side of the collection box. A water pumping pipe is installed on one side of the micro water pump. A connecting pipe is installed on one side of the micro water pump. A flow divider is installed on one side of the connecting pipe. A nozzle is installed at the bottom of the flow divider.

[0009] A drive motor is installed on one side of the pickling body, and a stirring shaft is provided on one side of the drive motor. A limit cylinder is installed on the inner wall of the pickling body, a feed inlet is installed on one side of the pickling body, and a discharge structure is provided on the far side of the pickling body.

[0010] Preferably, the pull-out plate is slidably connected inside the chute, and the water pump extends into the collection box from the side away from the pull-out plate.

[0011] Preferably, one side of the connecting pipe extends into the interior of the pickling body, and the diverter seat is installed at the top inside the pickling body.

[0012] Preferably, the nozzles are evenly distributed at the bottom of the flow divider, and one side of the stirring shaft is located inside the limiting cylinder.

[0013] Preferably, the discharge structure includes a discharge port located on the side of the pickling body away from the inlet. A baffle is provided inside the discharge port, and a snap-fit ​​groove is provided at the bottom end of the baffle. An internal groove is provided inside the pickling body below the discharge port, and a snap-fit ​​block is provided inside the internal groove. A return spring is fixed at the bottom end of the snap-fit ​​block, and a fixing block is fixed on one side of the return spring.

[0014] Preferably, the side of the reset spring away from the snap-fit ​​block is fixedly connected to the bottom end inside the built-in groove, and the side of the fixing block away from the reset spring extends to the outside of the pickling body.

[0015] Preferably, the snap-fit ​​block is disposed inside the snap-fit ​​groove, and the snap-fit ​​block and the baffle form an engaging structure through the snap-fit ​​groove.

[0016] The advantages of the hemp fiber acid washing device provided by this utility model are as follows:

[0017] By incorporating an acid washing structure, the collection box and the distribution seat are interconnected via a micro water pump, a water extraction pipe, and a connecting pipe. This allows the acidic solution inside the collection box to be drawn into the distribution seat by activating the micro water pump and then discharged through a nozzle. The sprayed liquid is filtered through a filter plate as it falls into the collection box, facilitating its subsequent reuse. This achieves the goal of facilitating the acid washing of hemp fibers while simultaneously recycling the acid washing solution.

[0018] By incorporating a discharge structure, when the baffle is rotated into the discharge port, the inclined edge of the snap-fit ​​block is pressed, causing it to move into the interior groove. Once the snap-fit ​​groove moves to the snap-fit ​​block's side, the return spring pushes the snap-fit ​​block to move into its interior, thus engaging and positioning the baffle. This prevents the baffle from shifting position and facilitates pulling the fixing block after pickling, moving the snap-fit ​​block away from the interior of the snap-fit ​​groove and engaging it in position. This achieves the purpose of easily blocking and discharging the pickled hemp fibers. Attached Figure Description

A water pumping pipe 306 is provided on one side of the miniature water pump 305. A connecting pipe is provided on one side of the miniature water pump 305. 307, a diversion seat 308 is provided on one side of the connecting pipe 307, a nozzle 309 is installed at the bottom of the diversion seat 308, the pull plate 303 is slidably connected inside the slide groove 302, the water pumping pipe 306 extends to the inside of the collection box 301 on the side away from the pull plate 303, the connecting pipe 307 extends to the inside of the pickling body 1 on one side, the diversion seat 308 is installed at the top inside the pickling body 1, the nozzles 309 are evenly distributed at the bottom of the diversion seat 308, and one side of the stirring shaft 5 is provided inside the limiting cylinder 6.

[0028] In the production process of hemp fiber, it is necessary to remove the impurities and degumme the fiber. This requires acid washing, and the addition of bio-enzymes to the acidic solution to improve the degumming effect. The acid washing structure 3 stores the acidic solution in the collection tank 301. The liquid is pumped into the diversion seat 308 by a micro water pump 305 and pipes on both sides, and then sprayed into the acid washing body 1 through the nozzle 309 at the bottom. During the acid washing process, impurities in the hemp fiber are carried out and discharged. The impurities are then filtered by the filter plate 304 inside the pull-out plate 303, and the filtered liquid falls into the collection tank 301 for recycling, thus greatly increasing the functionality of the device.

[0029] Reference Figure 4 and Figure 5As shown, a drive motor 4 is installed on one side of the pickling body 1, and a stirring shaft 5 is provided on one side of the drive motor 4. A limit cylinder 6 is installed on the inner wall of the pickling body 1.

The snap-fit ​​block 805 and the baffle 802 form a snap-fit ​​structure through the snap-fit ​​groove 803.

[0030] During the acid washing process of hemp fibers, the hemp fibers are added into the limiting cylinder 6 through the feed port 7. The outer wall of the limiting cylinder 6 is evenly provided with through grooves to prevent the hemp fibers from leaking out while facilitating the passage of acidic solution. In order to improve the efficiency and quality of acid washing of hemp fibers, the drive motor 4 is started to make the stirring shaft 5 rotate inside the limiting cylinder 6 to stir the hemp fibers, thereby increasing the contact area with the acidic solution and improving the acid washing effect. In order to prevent the hemp fibers from being discharged during the acid washing process, a discharge structure 8 is provided. A baffle 802 is provided inside the discharge port 801.
