Technical Field

[0001] The utility model belongs to the technical field of filling equipment, in particular to a filling equipment for the processing of heavy calcium carbonate. Background Technique

[0002] Heavy calcium carbonate, abbreviated as heavy calcium, is ground from natural carbonate minerals such as calcite, marble and limestone; it is a commonly used powdery inorganic filler, with high chemical purity, large inertness, not easy to have chemical reactions, good thermal stability, not decomposing below 400 °C, high whiteness, low oil absorption rate, low refractive index, soft, dry, without crystal water, low hardness, small abrasion value, non-toxic, odorless, tasteless and good dispersibility, etc. During its production and processing, it needs to be filled by filling equipment.

[0003] When the existing filling equipment for heavy calcium carbonate fills heavy calcium carbonate, it needs manual assistance to open the filling pipe for filling. After a can is filled, it is manually closed, the can is replaced, and then the filling pipe is opened again for filling. This filling method greatly increases the labor intensity of workers and reduces the filling efficiency. Therefore, there is an urgent need for a filling equipment for the processing of heavy calcium carbonate to solve this problem. Content of the Utility Model

[0004] The purpose of the utility model is to provide a filling equipment for the processing of heavy calcium carbonate to solve the problems put forward in the background technique.

[0005] To achieve the above purpose, the utility model provides the following technical scheme: A filling equipment for the processing of heavy calcium carbonate, including a bottom plate for installing the heavy calcium carbonate filling equipment, a top plate and a hydraulic cylinder. The hydraulic cylinder is installed on the top surface of the top plate, and its telescopic end slides and extends below the top plate and is fixedly connected with a vertical pipe for filling heavy calcium carbonate. A sleeve is slidably sleeved outside the vertical pipe. An L-shaped rod is fixedly connected to the lower part of the inner wall of the sleeve. A fixed ring is fixedly connected inside the vertical pipe. The end of the L-shaped rod slides through the fixed ring and is fixedly connected with a sealing ball, and the sealing ball matches the inner hole of the fixed ring. A sealing ring is fixedly connected to the inner wall of the sleeve, and the sealing ring is located below the L-shaped rod;

[0006] Arc-shaped plates are symmetrically and fixedly connected to the outer wall of the vertical pipe and the inner wall of the sleeve. A limiting cylinder is fixedly connected to the top surface of the arc-shaped plate on the outer wall of the vertical pipe. A connecting rod is slidably connected inside the limiting cylinder. The top surface of the connecting rod is fixedly connected to the arc-shaped plate on the inner wall of the sleeve. A spring is fixedly connected to the inner wall of the limiting cylinder, and the end of the spring is fixedly connected to the connecting rod.

[0007] Preferably, limiting grooves are symmetrically opened on the inner wall of the limiting cylinder, and two limiting blocks are symmetrically and fixedly connected to the outer wall of the connecting rod.

[0008] Preferably, the two limiting blocks fixedly connected to the outer wall of the connecting rod are respectively slidably connected to the inside of two limiting grooves formed in the inner wall of the limiting cylinder.

[0009] Preferably, the inner diameter of the sealing ring on the inner wall of the sleeve is matched with that of the vertical pipe.

[0010] Preferably, a damping rod is fixedly connected between the arc-shaped plate fixedly connected to the outer wall of the vertical pipe and the arc-shaped plate fixedly connected to the inner wall of the sleeve.

[0011] Preferably, a vertical groove is formed in the side wall of the vertical pipe, and the L-shaped rod slidably extends into the inside of the vertical groove.

[0012] Compared with the prior art, the technical effects and advantages of the present utility model are as follows:

[0013] For the filling device for heavy calcium carbonate processing, by starting the hydraulic cylinder to drive the vertical pipe and the sleeve to move towards the can mouth on the bottom plate. At this time, since the bottom of the sleeve is lower than the bottom of the vertical pipe, the sleeve will contact the can mouth first. At this time, since a sealing ring is fixedly connected inside the sleeve and the inner diameter of the sealing ring is smaller than the inner diameter of the can mouth, the sealing ring will abut against the can mouth. Thanks to the setting of the sealing ring, as the vertical pipe continues to move downward, the sealing ring will be squeezed between the can mouth and the lower end of the vertical pipe and form a seal between the two.

[0014] For the filling device for heavy calcium carbonate processing, pushing the vertical pipe downward will stretch the limiting cylinder, the connecting rod and the spring installed between the vertical pipe and the sleeve, and at the same time make the sleeve move upward relative to the vertical pipe, so that the L-shaped rod and the sealing ball in the vertical pipe move upward relatively, thereby opening the inner hole of the fixing ring in the vertical pipe. When the inner hole of the fixing ring is opened, the lower end of the vertical pipe will be communicated with and sealed with the can mouth, so as to fill the heavy calcium carbonate through the vertical pipe.

[0015] For the filling device for heavy calcium carbonate processing, after the filling is completed, the vertical pipe is lifted. At this time, the spring will pull the connecting rod and the limiting cylinder back to the initial state, so that the sleeve moves downward relative to the vertical pipe, and at the same time drives the L-shaped rod and the sealing ball to move downward until the sealing ball seals the inner hole of the fixing ring in the vertical pipe. Compared with the prior art, this device can automatically fill the heavy calcium carbonate, and can automatically close the filling pipe after the filling is completed, thus greatly improving the filling efficiency of the heavy calcium carbonate.

[0025] In the following description, a large number of specific details are given to provide a more thorough understanding of the present invention. However, it is obvious to those skilled in the art that the present invention can be implemented without one or more of these details. In other examples, in order to avoid confusion with the present invention, some well-known technical features in the art are not described.

[0026] Unless otherwise defined, the up, down, left, right, front, back, inner and outer directions involved in this article are based on the up, down, left, right, front, back, inner and outer directions in the figures shown in the present invention, and are hereby explained together.

[0027] The connection method can adopt existing methods such as bonding, welding, bolt connection, etc., according to actual needs.

[0028] Such asFigures 1 to 6 A filling device for heavy calcium carbonate processing shown in the figure includes a bottom plate 1 for installing the heavy calcium carbonate filling device, a top plate 2, and a hydraulic cylinder. The hydraulic cylinder is installed on the top surface of the top plate 2, and its telescopic end slides and extends below the top plate 2 and is fixedly connected to a vertical pipe 3 for filling heavy calcium carbonate. A hose for conveying heavy calcium carbonate is communicated with the side wall of the vertical pipe 3;

[0029] A sleeve 5 is slidably sleeved outside the vertical pipe 3. A L-shaped rod 8 is fixedly connected to the lower part of the inner wall of the sleeve 5. The connecting end of the L-shaped rod 8 with the inner wall of the sleeve 5 is horizontal, and the end extending into the vertical pipe 3 is vertical;

[0030] A fixed ring 9 is fixedly connected inside the vertical pipe 3. The end of the L-shaped rod 8 slides through the fixed ring 9 and is fixedly connected to a sealing ball 10, and the sealing ball 10 matches the inner hole of the fixed ring 9, so as to contact the inner hole of the fixed ring 9 through the sealing ball 10 and seal the inner hole of the fixed ring 9;

[0031] A sealing ring 4 is fixedly connected to the inner wall of the sleeve 5. The sealing ring 4 is located below the L-shaped rod 8. Since the sealing ring 4 is fixedly connected inside the sleeve 5 and the inner diameter of the sealing ring 4 is smaller than the inner diameter of the tank mouth, the sealing ring 4 will abut against the tank mouth. Thanks to the setting of the sealing ring 4, as the vertical pipe 3 continues to move downwards, the sealing ring 4 will be squeezed between the tank mouth and the lower end of the vertical pipe 3 and form a seal between the two, thereby preventing heavy calcium carbonate from leaking during filling;

[0032] Arc-shaped plates 11 are symmetrically and fixedly connected to the outer wall of the vertical pipe 3 and the inner wall of the sleeve 5. A limiting cylinder 12 is fixedly connected to the top surface of the arc-shaped plate 11 on the outer wall of the vertical pipe 3. A connecting rod 13 is slidably connected inside the limiting cylinder 12. The top surface of the connecting rod 13 is fixedly connected to the arc-shaped plate 11 on the inner wall of the sleeve 5. A spring 14 is fixedly connected to the inner wall of the limiting cylinder 12. The end of the spring 14 is fixedly connected to the connecting rod 13. The spring 14 will push the connecting rod 13 to extend outwards of the limiting cylinder 12. The arc-shaped plate 11 connected to the connecting rod 13 is fixedly connected to the vertical pipe 3, and the vertical pipe 3 is fixedly arranged. Therefore, the limiting cylinder 12 and the sleeve 5 will be pushed downwards below the vertical pipe 3, and the bottom of the sleeve 5 will be lower than the bottom of the vertical pipe 3.

[0033] Limiting grooves are symmetrically formed on the inner wall of the limiting cylinder 12. Two limiting blocks 15 are symmetrically and fixedly connected to the outer wall of the connecting rod 13. The two limiting blocks 15 fixedly connected to the outer wall of the connecting rod 13 are respectively slidably connected inside the two limiting grooves formed on the inner wall of the limiting cylinder 12. For the two limiting blocks 15 fixedly connected to the outer wall of the connecting rod 13 are respectively slidably connected inside the two limiting grooves formed on the inner wall of the limiting cylinder 12, so as to effectively limit the sliding direction of the connecting rod 13.

[0034] The inner diameter of the sealing ring 4 on the inner wall of the sleeve 5 matches that of the vertical pipe 3, and the diameter of the vertical pipe 3 is the same as that of the mouth of the can. Therefore, as the vertical pipe 3 moves downward, the sealing ring 4 will be squeezed between the vertical pipe 3 and the mouth of the can to form a seal.

[0035] A damping rod 6 is fixedly connected between the arc-shaped plate 11 fixedly connected to the outer wall of the vertical pipe 3 and the arc-shaped plate 11 fixedly connected to the inner wall of the sleeve 5. Thanks to the setting of the damping rod 6, it can effectively prevent the vibration generated during the operation of the device from being transmitted to the spring 14, causing the spring 14 to vibrate, and driving the sleeve 5 to vibrate through the spring 14.

[0036] A vertical groove 7 is formed on the side wall of the vertical pipe 3, and the L-shaped rod 8 slides and extends into the interior of the vertical groove 7. Thanks to the setting of the vertical groove 7, the relative moving stroke of the L-shaped rod 8 can be increased, so that the inner hole of the fixing ring 9 in the vertical pipe 3 can be opened more thoroughly.

[0037] Working principle

[0038] When the filling equipment for heavy calcium carbonate processing is in use, first place the can to be filled on the top surface of the bottom plate 1, and then start the hydraulic cylinder. The hydraulic cylinder drives the vertical pipe 3 fixedly connected to its telescopic end to move towards the mouth of the can. At this time, since the bottom of the sleeve 5 outside the vertical pipe 3 is lower than the bottom of the vertical pipe 3, the sleeve 5 will be sleeved on the mouth of the can first. At the same time, since a sealing ring 4 is fixedly sleeved in the sleeve 5, the sealing ring 4 will abut against the mouth of the can to stop the movement of the sleeve 5. At this time, continue to push the vertical pipe 3 downward through the hydraulic cylinder. At this time, the limiting cylinder 12, the connecting rod 13 installed between the arc-shaped plates 11 fixedly connected to the inner wall of the sleeve 5 outside the vertical pipe 3 and the spring 14 inside the limiting cylinder 12 will be stretched as the vertical pipe 3 moves downward. At this time, the sleeve 5 is stationary and the downward movement of the vertical pipe 3 will cause the L-shaped rod 8 fixedly connected inside the sleeve 5 and the sealing ball 10 fixedly connected to the end of the L-shaped rod 8 to move relatively upward. As the sealing ball 10 moves upward, it will move away from the inner wall of the fixing ring 9 fixedly connected inside the vertical pipe 3, thereby opening the inner hole of the fixing ring 9 to allow the heavy calcium carbonate to flow out. At the same time as the inner hole of the fixing ring 9 is opened, the lower end of the vertical pipe 3 will be in pressing contact with the sealing ring 4 installed on the inner wall of the sleeve 5. Thus, the vertical pipe 3 and the mouth of the can are sealed through the sealing ring 4, and the heavy calcium carbonate is filled at the same time. When the filling is completed, reverse the hydraulic cylinder to drive the vertical pipe 3 to move upward. Similarly, when the vertical pipe 3 moves upward and the sleeve 5 is stationary, the L-shaped rod 8 fixedly connected inside the sleeve 5 and the sealing ball 10 will move relatively downward until the sealing ball 10 seals the inner hole of the fixing ring 9 on the inner wall of the vertical pipe 3. At the same time, when the vertical pipe 3 moves upward, the spring 14, the limiting cylinder 12 and the connecting rod 13 will return to their initial states.
