Description

Technical Field

[0001] The utility model relates to the technical field of dosing equipment, in particular to a material unloading weighing device in a dosing room. Background Art

[0002] With the continuous development of society, the amount of various sewage is increasing. If it is discharged directly without treatment, it will seriously pollute the environment. In the sewage treatment process, dry powder medicines need to be added. Generally, in the process of adding a large amount, the medicines to be added are weighed with a floor scale first, and the medicines are completely placed on the floor scale. Each weighing requires lifting or moving the medicines for weighing, which is inconvenient to operate and has certain safety hazards.

[0003] A Chinese patent discloses a weighing device for dosing room (authorization announcement number CN208898133U). The patent technology has a simple structure and low cost. It effectively solves the problem that weighing in the dosing room requires constant lifting or diversion of drugs, which is inconvenient to operate and has certain safety hazards. It has high operational safety, is more environmentally friendly, and is convenient for measurement. It can display the latest weighing results in real time.

[0004] However, it has certain disadvantages: it uses a buffer funnel to prevent excessive addition of medicine at one time and cause waste. The dry powder medicine needs to pass through the buffer funnel during the falling process, which will cause collisions with the buffer funnel. The raised powder adheres to the inner wall of the buffer funnel and causes waste. Over time, too much powder accumulates and is difficult to clean. Utility Model Content

[0005] The utility model aims to provide a weighing device for feeding materials in a dosing room to solve the problems raised in the above-mentioned background technology.

[0006] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0007] A weighing device for unloading materials in a dosing room comprises a weighing scale, a silo is installed above the weighing scale, a valve is installed at the lower end of the silo, and support plates are installed on the front and rear surfaces of the silo, a buffer funnel is installed between the two support plates and below the silo, a conveyor belt is installed between the weighing scale and the buffer funnel, a fixed gear is installed on the outer surface of the buffer funnel, and a support ring is installed on the outer surface of the buffer funnel above the fixed gear, a slide groove is opened on the outer surface of the support ring, a slide plate is slidably connected to the inside of the slide groove, a cleaning mechanism is provided on the upper surface of the slide plate, and a driving mechanism is provided at the front end of the slide plate.

DETAILED DESCRIPTION

[0021] See also Figure 1 In an embodiment of the utility model, a weighing device for unloading materials in a dosing room includes a weighing scale 1, a silo 2 is installed above the weighing scale 1, a valve 3 is installed at the lower end of the silo 2, and support plates 4 are installed on the front and rear surfaces of the silo 2, the lower end of the support plate 4 is installed on the upper surface of the weighing scale 1, a buffer funnel 5 is installed between the two support plates 4 and below the silo 2, the valve 3 is directly opposite to the buffer funnel 5, and a conveyor belt 6 is installed between the weighing scale 1 and the buffer funnel 5;

[0022] Powdered medicine is placed in silo 2;

[0023] The valve 3 is preferably an electric valve. The weighing scale 1, the valve 3, and the conveyor belt 6 are all electrically connected to the external control system. When the valve 3 is opened to release the material, the powder medicine in the silo 2 will decrease, and the weight pressed on the weighing scale 1 will decrease. When the reduction amount reaches the required dosing material, the external control system will control the valve 3 to close.

[0024] The conveyor belt 6 is used to convey the container for receiving materials. When the valve 3 is opened, the powder medicine will fall into the container.

[0025] The buffer funnel 5 is preferably conical in shape, and is used to buffer the powder medicine below to reduce the impact force of the falling powder medicine. The lower end opening of the buffer funnel 5 is smaller than the lower end discharge port of the valve 3.

[0026] exist Figures 1 to 4 Middle: A fixed gear 7 is installed on the outer surface of the buffer funnel 5, and a support ring 8 is installed on the outer surface of the buffer funnel 5 above the fixed gear 7. A slide groove 9 is opened on the outer surface of the support ring 8, and a slide plate 10 is slidably connected inside the slide groove 9. A cleaning mechanism 11 is arranged on the upper surface of the slide plate 10. The cleaning mechanism 11 includes a connecting plate 12. A connecting rod 13 is installed on the upper end of the connecting plate 12. The lower end of the connecting rod 13 is installed on the upper surface of the slide plate 10. A cleaning pad 14 is installed on one side surface of the connecting plate 12. The cleaning pad 14 fits the inner surface of the buffer funnel 5. A driving mechanism 15 is arranged at the front end of the slide plate 10. The driving mechanism 15 includes a motor 16. The motor 16 is installed on the upper surface of the slide plate 10. A mounting rod 17 is installed on the output end of the motor 16. The mounting rod 17 movably penetrates the slide plate 10. A moving gear 18 is installed on the lower end of the mounting rod 17. The fixed gear 7 is meshed and connected to the moving gear 18.

[0027] The cleaning pad 14 is preferably made of sponge and rubber;

[0028] The motor 16 drives the moving gear 18 to rotate. Since the fixed gear 7 is meshed and connected to the moving gear 18, the moving gear 18 drives the slide plate 10 to rotate around the support ring 8, and the cleaning pad 14 cleans the inner wall of the buffer funnel 5, so that the adhered powder medicine is scraped off;

[0029] The motor 16 is a variable frequency motor, and the rotation speed can be adjusted to avoid dust caused by excessive rotation speed.

[0030] The working principle of the utility model is: when in use, the container is placed on the conveyor belt 6, and after the conveyor belt 6 drives the container to move to the bottom of the valve 3, the external control system controls the conveyor belt 6 to close, the valve 3 to open, and the powder medicine falls into the container. When the weighing scale 1 detects that the reduced weight reaches the set value, the valve 3 is closed, and the conveyor belt 6 is started to drive another container to move to the bottom of the valve 3, and the medicine is added repeatedly in this way; during the medicine adding process, the motor 16 drives the moving gear 18 to rotate through the mounting rod 17. Since the moving gear 18 is meshed and connected with the fixed gear 7, the moving gear 18 will drive the slide plate 10 to rotate around the support ring 8, and the connecting plate 12 will drive the cleaning pad 14 to clean the inside of the buffer funnel 5, and scrape the powder medicine on the inner wall of the buffer funnel 5.
