Description

Technical Field

[0001] The utility model belongs to the field of filling equipment, and in particular relates to industrial-grade anhydrous ferrous sulfate quantitative filling equipment. Background Art

[0002] Anhydrous ferrous sulfate is commonly used in different fields such as water treatment, electroplating, agriculture and medicine. In water treatment, it can be used as an oxidant and disinfectant; in electroplating, it is used as a catalyst for electroplating primer and iron plating process; in agriculture, it can be used as a fertilizer and pesticide component. Anhydrous ferrous sulfate is generally powdery or granular at room temperature.

[0003] When anhydrous ferrous sulfate is in powder form and quantitative filling is performed, the equipment is usually equipped with a metering device and a filling head. The metering device controls the amount of powder. Since the weight of powdered anhydrous ferrous sulfate is relatively light, during the filling process, the powder is prevented from being lifted up, and the filling head is extended into the tank to achieve quantitative filling of the powdered anhydrous ferrous sulfate.

[0004] However, during the filling process of the above-mentioned filling equipment, in order to prevent the can mouth from being misaligned due to the suspended filling, the filling head is inserted into the can for filling. In order to allow the filling head to smoothly extend into the can, a relatively wide mouth of the carbon can is set, so that the gap between the filling head and the can mouth is larger. During the filling, the powdered anhydrous ferrous sulfate falls due to the height difference, and some flying powder will be raised from the gap between the filling head and the can mouth of the carbon can to form dust, polluting the surrounding environment.

[0022] The technical solution of the utility model will be described clearly and completely in conjunction with the embodiments below. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of them. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] like Figures 1 to 3 As shown, an industrial-grade anhydrous ferrous sulfate quantitative filling equipment includes a support frame 1 and a quantitative feeding structure 2 for storing anhydrous ferrous sulfate. The quantitative feeding structure 2 is arranged on the top of the support frame 1. The filling equipment also includes a lifting structure and a protective component:

[0024] The lifting structure is arranged on the support frame 1, and the top of the support frame 1 is movably connected with a storage box 5 through the lifting structure. A feeding pipe 3 for conveying anhydrous ferrous sulfate is fixedly connected between the quantitative feeding structure 2 and the storage box 5, so that the quantitative feeding structure 2 can convey a certain amount of anhydrous ferrous sulfate to the storage box 5 through the feeding pipe 3. The feeding pipe 3 is a hose, and a discharge pipe 6 is fixedly connected to the bottom of the storage box 5. The discharge pipe 6 is provided with a solenoid valve 7, and the solenoid valve 7 is used to control the opening and closing of the filling process;

[0025] The protection component includes an anti-splash component and a dust-proof component. The anti-splash component is movably arranged at the bottom of the material storage box 5 and cooperates with the discharge pipe 6. The dust-proof component is slidably arranged with the discharge pipe 6.

[0026] In some specific embodiments, such as Figure 1 As shown, in order to facilitate driving the material storage box 5 to drive the discharge pipe 6 to move, the lifting structure includes a lifting cylinder 4, the lifting cylinder 4 is fixedly connected to the lower surface of the top plate of the support frame 1, and the driving end of the lifting cylinder 4 is fixedly connected to the top of the material storage box 5. The lifting cylinder 4 can drive the material storage box 5 and the discharge pipe 6 to rise and fall synchronously, so that the discharge port of the discharge pipe 6 can be extended into the can to be filled.

[0027] In some specific embodiments, such as Figure 3 As shown, in order to facilitate the shielding of flying powder of anhydrous ferrous sulfate, the anti-splash component includes a sealing cover 8, a fixed sleeve 9 and a pressure sensor 11. The sealing cover 8 is sleeved on the outside of the discharge pipe 6 and is slidably connected to the discharge pipe 6. A sealing gasket 16 is fixed on the inside of the sealing cover 8 by glue. The discharge pipe 6 passes through the sealing gasket 16. A spring 12 is connected between the storage box 5 and the sealing cover 8. The top of the sealing cover 8 is connected to the bottom of the storage box 5 through the spring 12. A slide bar 10 is fixed to the top of the sealing cover 8. One end of the fixed sleeve 9 is slidably sleeved on the outside of the slide bar 10, and the other end is fixedly connected to the bottom of the storage box 5. An induction component is provided inside the fixed sleeve 9, and the induction component cooperates with the slide bar 10. The bottom of the sealing cover 8 is cooperated with the dustproof component.

[0028] The lifting cylinder 4 is operated to push the storage box 5 and the discharge pipe 6 to move downward synchronously. The discharge pipe 6 can drive the sealing cover 8 to move downward until it contacts the bottle mouth. When the protective cover sealing cover 8 and the bottle mouth gradually generate pressure, the position of the sealing cover 8 is fixed, and the discharge pipe 6 moves downward relative to the sealing cover 8 until the discharge port of the discharge pipe 6 extends into the can to be filled. At the same time, the spring 12 is deformed and the slide rod 10 slides upward.

[0029] In some specific embodiments, such as Figure 2 As shown, in order to facilitate shielding of cans with different diameters of bottle mouths, the sealing cover 8 is in the shape of an inverted funnel, and the outer side of the bottle mouth can fit with the inner wall of the sealing cover 8.

[0030] In some specific embodiments, such as Figure 2 As shown, in order to facilitate the control of the lifting cylinder 4 and the solenoid valve 7, the sensing component includes a pressure sensor 11, and the pressure sensor 11 is connected to the controller. The controller is provided with a fixed threshold value. The pressure sensor 11 is fixedly arranged at the inner bottom of the fixed sleeve 9, and the pressure sensor 11 is aligned above the slide rod 10. When the slide rod 10 moves upward to fit the pressure sensor 11, the pressure sensor 11 will generate a pressure value. The pressure sensor 11 is electrically connected to the lifting cylinder 4 and the solenoid valve 7 respectively. After exceeding the fixed threshold value, the pressure sensor 11 controls the opening and closing of the lifting cylinder 4 and the solenoid valve 7.

[0031] The slide bar 10 slides upward to apply pressure to the pressure sensor 11. When the appropriate pressure is reached, the controller stops the lifting cylinder 4 from descending. The elastic action of the spring 12 can push the sealing cover 8 to be in close contact with the bottle mouth, and a sealing gasket 16 is arranged on the inner side of the sealing cover 8, so that the sealing gasket 16 is in close contact with the outer wall of the bottle mouth, thereby sealing the bottle mouth. At this time, the controller opens the solenoid valve 7 to transport anhydrous ferrous sulfate for output filling. Since the sealing cover 8 is in the shape of an inverted funnel, the sealing cover 8 can seal bottle mouths of different diameters.

[0032] In some specific embodiments, such as Figure 3 As shown, in order to prevent a large amount of dust from entering the discharge pipe 6, the dust-proof component includes a straight cylinder 13 and a dust-proof pad 14. The straight cylinder 13 is fixed on the inner side of the sealing cover 8, and the straight cylinder 13 is located on the outer side of the discharge pipe 6. A dust-proof pad 14 is fixed on the bottom of the straight cylinder 13. A cross hole 15 is opened on the dust-proof pad 14. The cross hole 15 cooperates with the discharge pipe 6. The discharge pipe 6 can extend through the cross hole 15, and can also be retracted to between the straight cylinder 13 and the dust-proof pad 14.

[0033] When the filling is completed, the lifting cylinder 4 is driven in reverse, and the elastic action of the discharge pipe 6 can exert a downward force on the sealing cover 8, so that the sealing cover 8 slides downward along the discharge pipe 6, and the discharge pipe 6 moves upward relative to the sealing cover 8, thereby causing the discharge port of the discharge pipe 6 to shrink into the straight tube 13 and the dustproof pad 14, thereby preventing most dust from entering the discharge pipe 6.

[0034] In order for those skilled in the art to better understand the working principle of the embodiments of the present invention, the following is an explanation in conjunction with specific application scenarios:

[0035] When the bottle is in the bottle, the sealing cover 8 is moved downwards, and the bottle mouth is sealed. When the sealing cover 8 and the bottle mouth are gradually pressurized, the sealing cover 8 is fixed, and the discharge pipe 6 moves downwards relative to the sealing cover 8 until the discharge port of the discharge pipe 6 extends into the can to be filled. At the same time, the spring 12 is deformed, and the slide bar 10 slides upwards. The slide bar 10 slides upwards to apply pressure to the pressure sensor 11. After reaching the appropriate pressure, the controller stops the lifting cylinder 4 from descending. The elastic action of the spring 12 can push the sealing cover 8 to contact closely with the bottle mouth, and a sealing gasket 16 is arranged on the inner side of the sealing cover 8, so that the sealing gasket 16 is tightly fitted with the outer wall of the bottle mouth, thereby sealing the bottle mouth. At this time, the controller opens the solenoid valve 7 to transport anhydrous ferrous sulfate for output filling. Since the sealing cover 8 is in the shape of an inverted funnel, the sealing cover 8 can seal bottle mouths of different diameters.

[0036] When the filling is completed, the lifting cylinder 4 is driven in reverse, and the elastic action of the discharge pipe 6 can exert a downward force on the sealing cover 8, so that the sealing cover 8 slides downward along the discharge pipe 6, and the discharge pipe 6 moves upward relative to the sealing cover 8, thereby causing the discharge port of the discharge pipe 6 to shrink into the straight tube 13 and the dustproof pad 14, thereby preventing most dust from entering the discharge pipe 6.

[0037] The above embodiments are only used to illustrate the technical method of the utility model rather than to limit it. Although the utility model is described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical method of the utility model can be modified or replaced by equivalents without departing from the spirit and scope of the technical method of the utility model.
