Description

Technical Field

[0001] This utility model relates to the field of algae filament production and processing technology, specifically a high-efficiency cleaning screen for harvesting and cleaning spirulina filaments. Background Technology

[0002] Spirulina powder, after being harvested and processed, can be categorized into feed grade, food grade, and special-purpose grades based on its intended use. Feed-grade spirulina powder is generally used in aquaculture and livestock farming, while food-grade spirulina powder is used in health foods and added to other foods for human consumption. During the cultivation and harvesting process, due to spirulina's strong adsorption capacity, impurities are adsorbed on its surface. Therefore, the algal filaments need to be cleaned and filtered after harvesting. Existing high-efficiency cleaning devices use a method of agitating the algal liquid while filtering the algal liquid. However, improper agitation speed can easily cause algal breakage. To address this issue, a high-efficiency cleaning sieve for harvesting spirulina filaments is proposed. Utility Model Content

[0003] The purpose of this invention is to provide a high-efficiency cleaning sieve for harvesting spirulina filaments, in order to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution:

[0005] A high-efficiency cleaning sieve for harvesting Spirulina filaments, comprising:

[0006] There are two support bases, and a water collection tank is fixedly installed between the two ends of the two support bases;

[0007] A sieve frame is rotatably mounted between two support seats. A sieve screen is installed inside the sieve frame, and the sieve screen is used to drain water from the algae filaments.

[0008] The feed hopper is fixedly installed on a support at one end of the screen frame, and the feed hopper is used to feed material into the screen frame;

[0009] An output module is installed at the other end of the screen frame, and the output module is used to output the material inside the screen frame to the outside.

[0010] A backwash module is installed above one end of the screen frame. The backwash module is used to spray water onto the screen below.

[0011] Furthermore, the recoil module includes a protective shell, one end of which is fixedly connected to two crossbars, one end of which is fixedly installed with a sleeve, and the top of one of the toothed rings in the two support seats is fixedly connected to two sliding rods. The crossbars are slidably sleeved on the sliding rods through the sleeves, and a fastening bolt is screwed onto one side of the sleeves. A water spray pipe is fixedly installed on the protective shell.

[0012] Furthermore, the output module includes a discharge pipe, one end of which is fixedly installed with a discharge hopper communicating with the discharge pipe, a scraper is fixedly installed on one side of the top of the discharge hopper, the other end of the discharge pipe has a discharge port, an auger is rotatably installed inside the discharge pipe, and the discharge pipe is rotatably installed with an adjacent support base.

[0013] Furthermore, a rocker arm is fixedly installed on the outer wall of the discharge pipe, and a hydraulic rod is rotatably installed between one end of the rocker arm and the adjacent support seat.

[0014] Furthermore, a gear ring is fixedly installed at the other end of the screen frame, a drive shaft is provided on one side of the gear ring, the drive shaft is rotatably mounted on an adjacent support, and a gear that meshes with the gear ring is fixedly installed at one end of the drive shaft.

[0016] Furthermore, both ends of the screen frame are fixedly equipped with support tiles, and the top of the support base is equipped with multiple support bearings, which are used to support the support tiles.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] 1. With the backwash module in place, water is sprayed downwards from the spray pipe. After the algae filaments move to the top of the screen, the clean water passes through the screen to wet the algae filaments, causing them to detach from the top of the screen and fall. The impact of the falling algae filaments mixed with clean water causes impurities attached to the algae filaments to enter the water. Subsequently, the wastewater leaks through the screen into the collection tank, achieving efficient cleaning of the algae filaments. When the algae filaments accumulate at the bottom of the screen frame, they automatically overflow to the other end of the screen frame. The output module outputs the algae filaments from the other end of the screen frame, thus achieving continuous cleaning and output of the algae filaments. Attached Figure Description

Detailed Implementation

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Please see Figures 1-4 In this embodiment of the invention, a high-efficiency cleaning sieve for harvesting spirulina filaments includes a sieve frame 200, a support base 300, a backflushing module 400, an output module 500, and a feed hopper 600. There are two support bases 300, and a water collection trough 100 is fixedly installed between the two ends of each support base 300. The sieve frame 200 is rotatably mounted between the two support bases 300. A screen 210 is installed inside the sieve frame 200 for draining the spirulina filaments. The feed hopper 600 is fixedly installed on the support base 300 at one end of the sieve frame 200 and is used to feed material into the sieve frame 200. The output module 500 is installed on the other end of the sieve frame 200. At one end, the output module 500 is used to output the material inside the screen frame 200 outward. The backflushing module 400 is installed above one end of the screen frame 200. The backflushing module 400 is used to spray water onto the screen 210 below. The backflushing module 400 includes a protective shell 420. Two crossbars 410 are fixedly connected to one end of the protective shell 420. A sleeve 440 is fixedly installed at one end of the crossbar 410. Two sliding rods 320 are fixedly connected to the top of one of the toothed rings 330 in the two support seats 300. The crossbar 410 is slidably sleeved on the sliding rod 320 through the sleeve 440. A fastening bolt 450 is screwed onto one side of the sleeve 440. A water spray pipe 430 is fixedly installed on the protective shell 420.

[0029] Specifically, the algae filament mixture is poured into the feed hopper 600 and slides into the screen 210. Wastewater in the mixture flows out through the screen 210, while the algae filaments are intercepted and retained within the screen 210. The wastewater is collected by the collection tank 100. The screen frame 200 rotates, causing the algae filaments to tumble. After draining, the algae filaments adhere to the inner wall of the screen 210, causing them to tumble along with the screen. A water pump is connected to the spray pipe 430 to supply clean water, which sprays downwards. After the algae filaments move to the top of the screen 210, the clean water passes through... The algae filaments are moistened by the screen 210, causing them to detach from the top of the screen 210 and fall. The impact of the falling algae filaments mixed with clean water causes impurities attached to the algae filaments to enter the water. Subsequently, the wastewater leaks through the screen 210 into the water collection tank 100, achieving efficient cleaning of the algae filaments. When the algae filaments accumulate at the bottom of the screen frame 200, they automatically overflow to the other end of the screen frame 200. The output module 500 outputs the algae filaments from the other end of the screen frame 200, thereby achieving continuous cleaning and output of the algae filaments. The natural falling impact of the moistened algae filaments can effectively reduce the breakage of the algae.

[0030] Example 1

[0031] like Figures 2-7 As shown, in this embodiment, the output module 500 includes a discharge pipe 510. A discharge hopper 520 communicating with the discharge pipe 510 is fixedly installed at one end of the discharge pipe 510. A scraper 521 is fixedly installed on one side of the top of the discharge hopper 520. A discharge port 540 is opened at the other end of the discharge pipe 510. An auger 550 is rotatably installed inside the discharge pipe 510. The discharge pipe 510 is rotatably installed with an adjacent support base 300. A rocker arm 530 is fixedly installed on the outer wall of the discharge pipe 510. One end of the rocker arm 530 is rotatably installed with the adjacent support base 300. A hydraulic rod 230 is installed, and a gear ring 330 is fixedly installed at the other end of the screen frame 200. A drive shaft 340 is provided on one side of the gear ring 330. The drive shaft 340 is rotatably mounted on the adjacent support base 300. A gear 350 that meshes with the gear ring 330 is fixedly installed at one end of the drive shaft 340. The axis of the discharge pipe 510 is located above the axis of the screen frame 200. Support tiles 220 are fixedly installed at both ends of the screen frame 200. Multiple support bearings 310 are installed at the top of the support base 300. The support bearings 310 are used to support the support tiles 220.

[0032] In this embodiment, an external motor drives the auger 550 and drive shaft 340 to rotate. The drive shaft 340 drives the screen frame 200 to rotate via gear 350 and gear ring 330. Due to the eccentric setting between the discharge pipe 510 and the screen frame 200, the hydraulic rod 230 drives the discharge pipe 510 to rotate. The discharge pipe 510 drives the discharge hopper 520 to deflect, thereby controlling the gap between the scraper 521 and the screen 210. When it is necessary to output outward, the scraper 521 contacts the screen 210, the screen frame 200 rotates, so that the algae fibers are scraped off by the scraper 521 and flow into the discharge pipe 510. The auger 550 rotates to output the algae fibers in the discharge pipe 510 outward.
