Description

Technical Field

[0001] This utility model relates to the field of filling machine technology, specifically a cement grinding aid filling machine. Background Technology

[0002] Cement grinding aids are chemical additives that improve the effect and performance of cement powder. They can improve the fluidity of cement, enhance the grinding effect of cement in the mill, and thus reduce grinding energy consumption. According to the state, they are divided into powder and liquid. Regardless of whether they are powder or liquid, they need to be filled by a filling machine after production for subsequent transportation and use.

[0003] However, when existing cement grinding aids are filled using filling machines, the liquid cement grinding aids are composed of various chemical substances and have a certain degree of corrosiveness. Therefore, during filling, the filling port of the container is usually blocked to prevent the grinding aid from splashing out. After the grinding aid is filled into the container, the air inside cannot be discharged from the filling port, which leads to an increase in pressure inside the container during filling. This can easily cause the container to rupture due to excessive pressure. In addition, since the grinding aid liquid is usually pressurized by a power device when it is filled into the container, the grinding aid is poured into the container at a relatively fast speed. Since the filling port of commonly used filling containers is located on one side of the top of the container, the container is prone to tipping to one side when impacted by the high-speed rush of grinding aid, which is not conducive to maintaining the stability of the container during filling. Utility Model Content

[0004] The purpose of this invention is to provide a cement grinding aid filling machine to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a cement grinding aid filling machine, comprising a base, a tray placed at the top of the base, a container barrel on the top of the tray, a filling hole on one side of the top of the container barrel, a vertical plate fixedly connected to one side of the top of the base, a horizontal plate fixedly connected to the top of the vertical plate, an electric push rod installed at the top of the horizontal plate, a vertical cylinder provided at the output end of the electric push rod, a cavity provided inside the vertical cylinder, an exhaust pipe penetrating one side wall of the cavity, a filling pipe penetrating one side wall of the vertical cylinder, a conveying hose provided at the top of the filling pipe, a connecting rod fixedly connected to the back of the vertical cylinder, a vertical rod fixedly connected to the end of the connecting rod, and a pressure plate provided at the bottom end of the vertical rod.

[0006] Preferably, a metering pump is installed inside the vertical plate, and the input end and output end of the metering pump are respectively provided with a feed pipe and a discharge pipe, and the inside of the conveying hose is connected to the inside of the discharge pipe.

[0007] Preferably, the vertical rod is movably inserted into the horizontal plate, and the pressure plate is attached to the top of the container barrel through the vertical rod and the connecting rod.

[0008] Preferably, the vertical cylinder is movably connected to the filling hole via an electric push rod, and the cavity is connected to the interior of the filling hole via the vertical cylinder.

[0009] Preferably, the top of the tray has a groove, and the container is movably connected to the tray through the groove.

[0010] Preferably, a solenoid valve is provided at the junction of the filling pipe and the delivery hose, and the filling pipe is movably connected to the filling hole through a vertical cylinder.

[0011] Preferably, the interior of the exhaust pipe communicates with the interior of the cavity.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. This cement grinding aid filling machine, through the cavity inside the vertical cylinder and the exhaust pipe connected to the cavity, as well as the filling pipe with an outer diameter smaller than the filling hole at the top of the container, allows air inside the filling barrel to enter the cavity through the filling hole at the top and then be discharged through the exhaust pipe when the filling machine fills the cement grinding aid liquid into the container barrel. This ensures that the pressure inside the filling barrel can be balanced with the outside, thereby reducing the probability of the container barrel breaking due to excessive pressure during filling.

[0014] 2. This cement grinding aid filling machine, through a vertical cylinder, connecting rod, vertical rod, and pressure plate, allows the container to slide down via the connecting rod after the container is placed on the base of the filling machine through the tray. This pushes the vertical cylinder with an electric push rod, which in turn drives the vertical rod and pressure plate to slide down. This allows the pressure plate and vertical cylinder to press firmly against both sides of the top of the container, making it less likely for the container to tip over to one side when subjected to the impact of the pressurized, high-speed cement grinding aid. This helps the container maintain a stable state during filling. Attached Figure Description

[0023] like Figures 1 to 4As shown, the cement grinding aid filling machine of this embodiment includes a base 1, a tray 15 placed on the top of the base 1, a container 14 on the top of the tray 15, a filling hole 13 on one side of the top of the container 14, a vertical plate 2 fixedly connected to one side of the top of the base 1, a horizontal plate 5 fixedly connected to the top of the vertical plate 2, an electric push rod 8 installed on the top of the horizontal plate 5, a vertical cylinder 10 provided at the output end of the electric push rod 8, a cavity 17 provided inside the vertical cylinder 10, an exhaust pipe 9 passing through one side wall of the cavity 17, a filling pipe 11 passing through one side wall of the vertical cylinder 10, a conveying hose 3 provided at the top of the filling pipe 11, a connecting rod 7 fixedly connected to the back of the vertical cylinder 10, a vertical rod 4 fixedly connected to the end of the connecting rod 7, and a pressure plate 6 provided at the bottom end of the vertical rod 4.

[0024] Specifically, the pallet 15 is detachable, and a fork hole is provided on the front of the pallet 15 to facilitate the transfer of the container 14, which has been filled with grinding aid, by a forklift. The container 14 is a common chemical drum with good sealing performance. The top of the filling hole 13 protrudes from the top of the container 14, allowing the vertical cylinder 10 to engage with the filling hole 13, thereby reducing the probability of cement grinding aid liquid splashing out of the filling hole 13. The vertical plate 2 supports the horizontal plate 5, which in turn supports the electric push rod 8. The electric push rod 8 pushes the vertical cylinder 10 downward, allowing it to cover the filling hole 13 at the top of the container 14 before filling. A washer is also provided at the bottom of the vertical cylinder 10 to ensure that the vertical cylinder 10 fits tightly against the filling hole 13. The cavity 17 allows the air squeezed out of the container 14 to be discharged smoothly, thereby achieving pressure balance inside and outside the container 14 and reducing... The probability of container 14 rupturing due to excessive pressure is reduced. The function of the exhaust pipe 9 is to promptly discharge the gas squeezed into the cavity 17, thereby achieving pressure balance inside and outside container 14. The filling pipe 11 has an "L" shaped cross-section with its bottom opening facing downwards, allowing the bottom end of the filling pipe 11 to penetrate into the filling hole 13 after the vertical cylinder 10 covers it, thus enabling the cement grinding aid to smoothly pass through the filling hole 13 and enter the container 14. The function of the conveying hose 3 is to move the cement grinding aid into the filling pipe 11. The function of the connecting rod 7 is to achieve synchronous movement of the vertical rod 4 and the vertical cylinder 10. The function of the vertical rod 4 is to maintain the stability of the pressure plate 6. The pressure plate 6 is made of flexible silicone and can act synchronously with the vertical cylinder 10 on both sides of the top of container 14, thereby reducing the probability of container 14 tilting to one side during filling and helping container 14 maintain a stable state during filling.

[0025] Furthermore, a metering pump 18 is installed inside the vertical plate 2. The input end and output end of the metering pump 18 are respectively provided with a feed pipe 19 and a discharge pipe 20. The inside of the conveying hose 3 is connected to the inside of the discharge pipe 20. The metering pump 18 can quantitatively deliver cement grinding aid into the container 14, thereby reducing the probability of filling errors.

[0026] Furthermore, the vertical rod 4 and the horizontal plate 5 are movably interlocked, and the pressure plate 6 is attached to the top of the container barrel 14 through the vertical rod 4 and the connecting rod 7, so that the top of the vertical rod 4 can maintain better stability, thereby facilitating the pressure plate 6 to be pressed tightly against the top of the container barrel 14 through the vertical rod 4.

[0027] Furthermore, the vertical cylinder 10 is movably connected to the filling hole 13 via the electric push rod 8, and the cavity 17 is connected to the interior of the filling hole 13 via the vertical cylinder 10. Under the push of the electric push rod 8, the vertical cylinder 10 can be pressed against the top of the container 14, thereby fixing the container 14.

[0028] Furthermore, a groove 16 is provided at the top of the tray 15, and the container barrel 14 is movably connected to the tray 15 through the groove 16. The inner diameter of the groove 16 is adapted to the outer diameter of the container barrel 14, so that the container barrel 14 can sink into the top of the tray 15, which is more conducive to the stability of the container barrel 14 during filling.

[0029] Furthermore, a solenoid valve 12 is provided at the junction of the filling tube 11 and the delivery hose 3. The filling tube 11 is movably connected to the filling hole 13 through the vertical cylinder 10. The function of the solenoid valve 12 is to facilitate the control of the filling of the filling tube 11, thereby improving the filling control capability of the machine.

[0030] Furthermore, the interior of the exhaust pipe 9 is connected to the interior of the cavity 17, allowing the exhaust pipe 9 to smoothly discharge the gas inside the cavity 17, thereby achieving a balance of pressure inside and outside the container barrel 14.

[0031] The method of use in this embodiment is as follows: Before using this cement grinding aid filling machine, the end of the feed pipe 19 needs to be connected to the storage tank that provides the grinding aid raw materials. Then, the container 14 is placed on the base 1 via the tray 15, so that the filling hole 13 is aligned and placed below the filling pipe 11. Then, the filling machine is connected to the external power supply, and the electric push rod 8 is started, so that the electric push rod 8 drives the vertical cylinder 10 to slide down, causing the vertical cylinder 10 to drive the connecting rod 7 and the vertical rod 4 at the end of the connecting rod 7 to slide down until the bottom end of the vertical cylinder 10 covers the filling hole 13 and the filling pipe 11 is inserted into the filling hole 13. At the same time, after the pressure plate 6 at the bottom of the vertical rod 4 is pressed against the other side of the top of the container barrel 14, the metering pump 18 can be started. At this time, the metering pump 18 will pump the cement grinding aid into the delivery hose 3 in a metered amount. Then the cement grinding aid will enter the filling pipe 11 and enter the container barrel 14 through the filling pipe 11. As the cement grinding aid is poured into the container barrel 14, the air in the container barrel 14 will be squeezed into the cavity 17 of the vertical cylinder 10 through the filling hole 13, and then discharged to the outside air through the exhaust pipe 9 connected to the cavity 17, so that the pressure inside and outside the container barrel 14 can be kept balanced.

[0032] 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. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
