[0023] The following detailed description will further explain the present application with reference to the above-mentioned drawings. DETAILED DESCRIPTION

[0024] In order to facilitate the understanding of the present application, the present application will be described more fully below with reference to the accompanying drawings. The drawings show several embodiments of the present application. However, the present application can be realized in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the present application more thorough and comprehensive.

[0025] It should be noted that when an element is referred to as being "fixedly attached" to another element, it can be directly on the other element or there can be intervening elements. When an element is referred to as being "connected" to another element, it can be directly connected to the other element or intervening elements can be present. The terms "vertical", "horizontal", "left", "right", and the like as used herein are for purposes of illustration only.

[0026] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used in the description of the application herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the application. As used herein, the term "and / or" includes any and all combinations of one or more of the associated listed items.

[0027] Please refer to Figures 1 to 3 A hollow fiber membrane silk drying rack is provided, which comprises a base 100, a worm 200, two parallel rotating shafts 300, two turbines 400 with the same number of teeth, and four lifting rods 500.

[0028] Specifically, the worm 200 is rotatably arranged on the base 100. Optionally, a driver can be arranged on the base 100 to drive the worm 200 to rotate. Alternatively, the worm 200 can be driven to rotate by manual force. Two parallel arranged rotating shafts 300 are rotatably arranged on the base 100, and the two rotating shafts 300 are arranged on opposite sides of the worm 200. Two same-toothed turbines 400 are arranged on the two rotating shafts 300, and the two turbines 400 are engaged with the worm 200. When the worm 200 rotates, the worm 200 simultaneously drives the two turbines 400 to rotate, and then the rotation of the turbines 400 drives the rotating shafts 300 to rotate. Since the two turbines 400 have the same number of teeth, the rotating speeds of the two rotating shafts 300 are consistent at this time. Four lifting rods 500 are slidingly arranged on the base 100, and the top of the four lifting rods 500 is used to support the hollow fiber membrane to be dried. The top of the four lifting rods 500 is arranged in a flush manner to prevent the hollow fiber membrane from being tilted when being hung. When the lifting rod 500 slides up and down on the base 100, the top of the lifting rod 500 moves up and down relative to the base 100. The bottom end of the four lifting rods 500 is respectively connected to the end of the two rotating shafts 300 through a transmission mechanism 600. Since the rotating speeds of the two rotating shafts 300 are the same, when the rotating shaft 300 rotates, each lifting rod 500 moves up and down relative to the base 100 synchronously, thereby ensuring that the top of the four lifting rods 500 is always at the same height, so that the hollow fiber membrane supported by the lifting rod 500 is kept in a horizontal state as a whole, avoiding tilting and causing the hollow fiber membrane to slide off the hollow fiber membrane drying rack.

[0029] In some optional embodiments, as shown in Figure 3 The lifting rod 500 is provided with a row of teeth 510, and the base 100 is provided with a sleeve 110. The lower end of the lifting rod 500 is partially arranged in the sleeve 110, and the lower end is arranged outside the sleeve 110. A gear 111 engaged with the row of teeth 510 is rotatably arranged in the sleeve 110. The gear 111 is connected to the rotating shaft 300 through the transmission mechanism 600. When the rotating shaft 300 drives the gear 111 to rotate through the transmission mechanism 600, the gear 111 drives the lifting rod 500 to slide up and down in the sleeve 110, thereby achieving the purpose of moving the lifting rod 500 up and down.

[0030] In some optional embodiments, as shown in Figure 1 The transmission mechanism 600 is a chain wheel mechanism. The driving wheel 610 of the chain wheel mechanism is sleeved with the rotating shaft 300, and at this time the rotating shaft 300 is synchronous with the driving wheel 610. The driven wheel 620 of the chain wheel mechanism 600 is rotatably arranged on the sleeve 110, and the driving wheel 610 drives the driven wheel 620 to rotate through the chain 630. The driven wheel 620 is coaxially arranged with the gear 111, so that the gear 111 rotates synchronously when the driven wheel 620 rotates.

[0031] In order to prevent the pressure applied by the hollow fiber membrane mounted on the lifting rod 500 from moving the lifting rod 500 downward, in some optional embodiments, as shown in Figure 3 the part of the lifting rod 500 outside the sleeve 110 is provided with a plurality of pin holes 520 at intervals, and the height of the pin hole 520 corresponds to the required position height. When the lifting rod 500 is raised to the required height, the pin 530 at the height is inserted into the pin hole 520.

[0032] In some optional embodiments, in order to facilitate the mounting of the hollow fiber membrane, as shown in Figure 1 four lifting rods 500 are provided with a beam frame 640, and the beam frame 640 is provided with a hook 641, and the hollow fiber membrane is fixed on the hook 641 during use.

[0033] In some optional embodiments, in order to facilitate the movement of the position of the silk drying rack, as shown in Figure 1 , Figure 2 a universal wheel 700 is arranged at the bottom of the base 100.

[0034] In some optional embodiments, in order to stably maintain the position unchanged after moving the silk drying rack, the universal wheel 700 is preferably a self-locking universal wheel.

[0035] In some optional embodiments, as shown in Figure 1 in order to prevent the sewage dropped by the hollow fiber membrane during hanging from directly polluting the base 100, a partition plate 120 is arranged on the base 100, and specifically, the partition plate 120 is arranged above the sleeve 110, and cannot hinder the upward and downward movement of the lifting rod 500.

[0036] In some optional embodiments, in order to prevent the sewage dropped by the hollow fiber membrane during hanging from flowing along the partition plate 120 to the ground of the drying place and causing great pollution to the environment, a drainage channel is arranged on the partition plate 120. Alternatively, the middle part of the partition plate 120 can be arranged in a concave shape, or water grooves are uniformly distributed in the partition plate 120.
