Description

Technical Field

[0001] This utility model relates to the technical field of drying equipment, specifically a drying equipment for seaweed fertilizer production. Background Technology

[0002] Seaweed fertilizer is an organic fertilizer formed by breaking the cell walls of fast-growing large seaweed using a special method to release its contents. Besides retaining the rich minerals and trace elements found in seaweed, it also contains many bioactive substances that promote crop growth and improve crop yield and quality. In the production process of seaweed fertilizer, the natural seaweed is first dried after removing impurities and foreign matter. Then, the dried seaweed undergoes a series of treatments, including high-temperature salt removal, crushing, stirring, and centrifugation, to finally obtain the seaweed fertilizer.

[0003] For example, the utility model patent with patent application number 202321635611.4 provides a drying device for seaweed fertilizer production, including a base, a plurality of pulleys fixedly connected to the lower end of the base, a pad fixedly connected to the upper end of the base, a shell fixedly connected to the upper end of the pad, an inner bottom layer provided in the shell, a heat pipe fixedly connected inside the inner layer, a discharge port fixedly connected to the front end of the shell, and a plurality of servo motors fixedly connected to the left side of the shell. This drying equipment for seaweed fertilizer production features an inclined outer shell. After the seaweed fertilizer is introduced into the shell through the feed pipe, it spreads at the bottom of the shell under gravity, facilitating uniform heating and drying. When the servo motor drives the stirring blades to stir the seaweed fertilizer, the air pump is activated to generate airflow, which is introduced from the upper front of the shell through the connecting pipe. The airflow enters from the upper front of the shell and exits through the feed pipe, accelerating the airflow on the surface of the seaweed fertilizer and carrying away the evaporated water vapor, resulting in good drying effect. However, the above technical solution still has the following shortcomings in actual use: the airflow exiting from the feed pipe inevitably carries dust, and direct discharge will pollute the atmospheric environment. Using dust removal equipment such as bag filters for treatment will increase equipment costs. Utility Model Content

[0012] The beneficial effects of this utility model are:

[0013] 1. This drying equipment for seaweed fertilizer production generates airflow through a blower and guides the airflow into a heating box through a pipeline. The airflow exchanges heat with an electric heater, and the hot air passes through a vibrating screen to dry the seaweed fertilizer. The induced draft fan is then activated to guide the airflow out through the outlet pipe. The airflow passes through a filter screen to filter the dust-laden gas, preventing it from being directly discharged into the atmosphere. This eliminates the need for dust collection equipment such as bag filters, which helps reduce production costs.

[0014] 2. This drying equipment for seaweed fertilizer production uses a telescopic rod to move a movable plate, which in turn moves a scraping assembly via a movable rod. The moving scraper scrapes off the dust adhering to the filter screen, effectively preventing filter screen blockage and reducing waste. The anti-clogging spring ensures that even worn scrapers remain firmly against the filter screen, which not only helps remove dust but also extends the service life of individual scrapers.

[0021] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0022] Example: Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, this utility model discloses a drying device for seaweed fertilizer production, including a vibrating conveyor 1, a blower 8, and an induced draft fan 9. The vibrating conveyor 1 is equipped with a vibrating screen 12. A heating box 10 is connected to the bottom of the vibrating conveyor 1, and an electric heater 101 is installed inside the heating box 10. A dust cover 2 is installed on the top of the vibrating conveyor 1, and several air outlet pipes are connected to the top of the dust cover 2. A filter screen 22 is installed at one end of each air outlet pipe and is located inside the dust cover 2. An induced draft pipe 3 is provided above the dust cover 2 and is connected to the air outlet pipes through a pipe. A scraping mechanism is provided below the induced draft pipe 3. The blower 8 and the induced draft fan 9 are both installed on the frame of the vibrating conveyor 1. The air inlet of the induced draft fan 9 is connected to the induced draft pipe 3 through a pipe. The filter screen 22 can be made of stainless steel.

[0023] The electric heater 101 is started, and the airflow generated by the blower 8 is introduced into the heating box 10 through the pipe to exchange heat with the electric heater 101. The hot air passes through the vibrating screen 12 to dry the seaweed fertilizer. The induced draft fan 9 is started to lead the airflow out from the air outlet pipe. The dust-laden gas is filtered through the filter screen 22 to prevent the dust-laden gas from being directly discharged into the atmosphere. It does not require the use of dust removal equipment such as bag filters, which helps to reduce production costs.

[0024] The scraping mechanism consists of a movable rod 4, a movable plate 5, a telescopic rod 6, and several scraping components 7. The telescopic rod 6 is installed on the top of the dust cover 2, and its piston end is connected to the movable plate 5. The scraping components 7 are located at the bottom of the filter screen 22 and include a scraper 71 that abuts against the filter screen 22 and a support box 72. The support box 72 has at least one through hole, and a sliding rod 74 is slidably installed in the through hole. One end of the sliding rod 74 is connected to the scraper 71, and the other end is equipped with a baffle. A retaining spring 73 is also sleeved on the outside of the sliding rod 74. The retaining spring 73 is clamped between the inner wall of the support box 72 and the baffle. The two ends of the movable rod 4 are respectively connected to the movable plate 5 and the support box 72. The telescopic rod 6 can be an electric push rod.

[0025] The telescopic rod 6 drives the movable plate 5 to move, and the movable plate 5 drives the scraper assembly 7 to move via the movable rod 4. The moving scraper 71 scrapes off the dust attached to the filter screen 22, which can effectively prevent the filter screen 22 from clogging and reduce waste. The set clamping spring 73 can make the worn scraper 71 press firmly against the filter screen 22, which not only helps to scrape off the dust attached to the filter screen 22, but also extends the service life of a single scraper 71.

[0026] The air inlet of the blower 8 is equipped with an air filter, and the air outlet of the blower 8 is connected to the heating box 10 through a pipe. The air filter can prevent external dust and other particles from entering the drying equipment.

[0027] The dust cover 2 has a mounting through hole that slides with the movable rod 4. The top of the dust cover 2 is connected to a feed inlet 21.

[0029] The electric heater 101 is one of the following: heating wire, heating tube, or heating rod. Heating can be performed by selecting heating wire, heating tube, or heating rod as needed.

[0030] During operation, the seaweed fertilizer to be dried is fed into the equipment through the feed inlet 21. The seaweed fertilizer falls onto the vibrating screen 12. Then, the cover is closed, and the electric heater 101, blower 8, induced draft fan 9, and vibrating machine 1 are started. The excitation force generated by the vibrating motor causes the seaweed fertilizer on the vibrating screen 12 to move towards the discharge port 11. The blower 8 generates airflow, which is then guided through pipes into the heating box 10 for heat exchange with the electric heater 101. The hot air passes through the vibrating screen 12. The seaweed fertilizer is dried by starting the induced draft fan 9 and directing the airflow from the outlet pipe. The airflow is filtered through the filter screen 22 to remove dust. The dried seaweed fertilizer is then discharged through the discharge port 11. The blower 8 and the induced draft fan 9 are then turned off. The moving plate 5 is moved by the telescopic rod 6. The moving plate 5 moves the scraper assembly 7 by means of the movable rod 4. The moving scraper 71 scrapes off the dust attached to the filter screen 22. The scraped dust falls onto the vibrating conveyor belt 12 and is transported out along with the seaweed fertilizer on the vibrating conveyor belt 12.

[0031] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model.
