DETAILED DESCRIPTION

[0021] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. The described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0022] Reference Figure 1-Figure 3A polyformaldehyde production and filling equipment includes a shell 1, a tank 3 and an electric butterfly valve 14. The top outer wall of the shell 1 is fixed with a support frame 2 by bolts. The tank 3 is fixed in the support frame 2 by bolts. A discharge pipe 17 is welded to the bottom of the tank 3, and the discharge pipe 17 extends into the shell 1. A first funnel 19 is fixed by bolts to the top inner wall of the shell 1 below the discharge pipe 17. The first funnel 19 is provided with a filter assembly for screening polyformaldehyde. The electric butterfly valve 14 is fixed to the bottom of the first funnel 19 by bolts to close the first funnel 19. A second funnel 20 is fixed to the housing 1 directly below the first funnel 19 by bolts. An electric push rod 12 is fixed to the bottom inner wall of the housing 1 by bolts. A baffle 21 is fixed to one end of the telescopic portion of the electric push rod 12 by bolts. A weighing sensor 13 is fixed to the bottom of the baffle 21 by bolts. The model of the weighing sensor 13 is NS-TH12. A relief opening is opened on one side of the second funnel 20. The baffle 21 extends into the second funnel 20 through the relief opening to seal the second funnel 20. A filling port 5 is fixed to the bottom outer wall of the housing 1 by bolts. The bottom of the shell 1 is provided with a discharge port that connects the second funnel 20 with the filling port 5. The polyformaldehyde in the tank body 3 enters the shell 1 through the discharge pipe 17. The polyformaldehyde entering the shell 1 will fall into the first funnel 19 and be screened by the filter assembly. Then, the electric butterfly valve 14 is opened to allow the polyformaldehyde in the first funnel 19 to fall into the second funnel 20. At this time, since the baffle 21 closes the second funnel 20, the polyformaldehyde will accumulate in the second funnel 20. At the same time, the weighing sensor 13 on the baffle 21 will weigh the polyformaldehyde in the second funnel 20. The weight of the polyformaldehyde is weighed. When the weight of the polyformaldehyde reaches the set standard, the electric butterfly valve 14 is closed, thereby closing the first funnel 19, so that the first funnel 19 no longer discharges material, and then the electric push rod 12 is started. The electric push rod 12 contracts and drives the baffle 21 to move, so that the baffle 21 no longer closes the second funnel 20, so that the polyformaldehyde in the second funnel 20 enters the filling port 5 for filling, thereby performing quantitative filling of the polyformaldehyde, avoiding errors in the filling amount, and eliminating the need for secondary filling or manual weight reduction weighing, thereby improving the filling efficiency.

[0023] In the present invention, the filter assembly includes a screen 18, which is fixed in a first funnel 19 by bolts. The screen 18 is tilted, and a vibration motor 15 for vibrating and screening the screen 18 is fixed to one side of the first funnel 19 by bolts. When polyformaldehyde falls into the first funnel 19, it will be located on the screen 18. When the vibration motor 15 is started, the vibration motor 15 will vibrate the first funnel 19 and the screen 18, thereby causing the screen 18 to vibrate and screen the polyformaldehyde, so that the screen 18 can better screen the polyformaldehyde. The first funnel 19 On one side, a discharge pipe 9 is welded below the downwardly inclined position of the screen 18, and the discharge pipe 9 passes through the shell 1. A T-shaped push rod 11 is provided in the discharge pipe 9 to close the discharge pipe 9. A fixing block 10 is welded to the outside of the T-shaped push rod 11. The fixing block 10 is detachably connected to the discharge pipe 9 by bolts. When the fixing block 10 is removed from the discharge pipe 9, the T-shaped push rod 11 can be taken out from the discharge pipe 9. At this time, the polyformaldehyde that has not been screened by the screen 18 will be discharged through the discharge pipe 9, thereby preventing the polyformaldehyde from remaining on the screen 18;

[0024] In particular, a motor is fixed to the top outer wall of the tank body 3 by bolts, and one end of the motor output shaft passes through the tank body 3 and is connected to a spiral feeding rod 8 through a coupling, and the spiral feeding rod 8 extends into the discharge pipe 17. When the motor is started, the motor will drive the spiral feeding rod 8 to rotate, and the spiral feeding rod 8 will assist in discharging the polyformaldehyde. The outer side of the spiral feeding rod 8 is located at the top and is fixed with two scrapers 7 that fit the tank body 3 by bolts. The spiral feeding rod 8 will drive the scrapers 7 to rotate, and the scrapers 7 will scrape and clean the inner wall of the tank body 3, thereby preventing polyformaldehyde from adhering to the tank body 3. A plurality of static elimination rods 6 are fixed to one side of the scraper 7 by bolts. The scraper 7 will drive the static elimination rod 6 to rotate during rotation, so that the static elimination rod 6 eliminates static electricity on the polyformaldehyde. A feeding port 4 is provided on the top of the tank body 3, and a cover plate is clamped in the feeding port 4.

[0025] Working principle: When it is needed, the produced polyformaldehyde is added into the tank body 3 through the feeding port 4, and then the motor is started. The motor will drive the spiral feeding rod 8 to rotate, and the spiral feeding rod 8 will discharge the polyformaldehyde in the tank body 3 through the discharge pipe 17 into the shell 1, thereby assisting the discharge of the polyformaldehyde. The polyformaldehyde entering the shell 1 will fall into the first funnel 19 and be located on the screen 18. Then start the vibration motor 15 and open the electric butterfly valve 14. The vibration motor 15 will vibrate the first funnel 19 and the screen 18, so that the screen 18 vibrates and screens the polyformaldehyde. The polyformaldehyde passing through the screen 18 will fall into the second funnel 20. At this time, due to the baffle 21 entering the second funnel 20, The first funnel 19 is closed, so the polyformaldehyde will accumulate in the second funnel 20. At the same time, the weighing sensor 13 on the baffle 21 will weigh the weight of the polyformaldehyde in the second funnel 20. When the weight of the polyformaldehyde reaches the set standard, the electric butterfly valve 14 is closed, thereby closing the first funnel 19, so that the first funnel 19 no longer discharges material. Subsequently, the electric push rod 12 is started, and the electric push rod 12 contracts and drives the baffle 21 to move, so that the baffle 21 no longer closes the second funnel 20, so that the polyformaldehyde in the second funnel 20 enters the filling port 5 for filling, thereby performing quantitative filling of the polyformaldehyde, avoiding errors in the filling amount, and eliminating the need for secondary filling or manual weight reduction weighing, thereby improving the filling efficiency.
