Description

Technical Field

[0001] The utility model relates to the field of molten petrolatum filtration, in particular to a raw material feeding device for petrolatum production. Background Technique

[0002] Petrolatum is a semi-liquid mixture of alkane hydrocarbons or saturated hydrocarbons, also called petrolatum jelly, which is obtained by fractional distillation of petroleum. Its state is between solid and liquid at normal temperature, and it has three colors: brown, yellow, and white for different uses.

[0003] In the process of petrolatum production, using petroleum as the raw material, the fatty acids in petroleum are removed through refining, then a sulfuric acid catalyst is added for acidification, and then petrolatum is separated from petroleum through distillation and filtration. After deodorization and decolorization, the pigments and odors in petrolatum are removed to obtain the petrolatum raw material.

[0004] Before the petrolatum raw material is filled, it needs to be heated and melted to make it in a molten state, and then the molten petrolatum is transported to the filling machine through feeding for filling operations. During the above heating process, the water contained in petrolatum can be effectively removed by stirring. However, during the heating and feeding processes, the impurities contained in the raw materials need to be filtered. Since the molten petrolatum is viscous, during the filtration process, it is easy to have a situation where the pressure above and below the filter is inconsistent, resulting in the interruption of feeding. Moreover, during the filtration process, the filter screen is prone to being blocked, and at this time, the filter screen needs to be replaced. The existing replacement method is not convenient enough during the replacement process and cannot further improve the working efficiency of filter screen replacement. Content of the Utility Model

Specific embodiments

[0023] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0024] Please refer to Figures 1 to 4 , in the embodiment of the present utility model, a raw material feeding device for vaseline production includes a tank body 1. A liquid inlet pipe 2 is integrally formed on the outer periphery of the tank body 1, and a liquid outlet pipe 3 is integrally formed at the bottom end of the tank body 1. The inner cavities of the liquid inlet pipe 2 and the liquid outlet pipe 3 are communicated with the inner cavity of the tank body 1. A support frame 6 is installed below the output end of the liquid inlet pipe 2 on the inner wall of the tank body 1. Connection grooves 7 are equidistantly opened inside the support frame 6. A connection head 8 is installed in the connection groove 7 through a connection mechanism. A filter screen 9 is fixedly connected to the bottom end of the connection head 8; the connection mechanism includes a lifting assembly, an extrusion assembly, a reset assembly, and a plug-in board 10; a plurality of plug-in boards 10 are integrally formed on the bottom end of the protruding part of the upper half of the connection groove 7 circumferentially and equidistantly, and the plug-in board 10 penetrates to the lower part of the support frame 6; the lifting mechanism is rotatably connected to the top end of the connection head 8 and extends downward into the inside of the plug-in board 10. The extrusion assembly is slidably connected to the inside of the plug-in board 10 and is located below the lifting assembly. The reset assembly is arranged inside the plug-in board 10 and is located below the extrusion assembly.

[0025] In this embodiment: The liquid inlet pipe 2 and the liquid outlet pipe 3 are respectively connected to a liquid inlet peristaltic pump and a liquid outlet peristaltic pump through pipelines. The liquid inlet peristaltic pump inputs vaseline into the tank body 1 through the liquid inlet pipe 2. The vaseline entering the tank body 1 is filtered by the filter screen 9. The solid particle impurities contained in the vaseline are intercepted by the filter screen 9, and the vaseline oozing out from the filter screen 9 enters the lower part of the tank body 1 and then enters the liquid outlet pipe 3. Starting the liquid outlet peristaltic pump can discharge the filtered vaseline.

[0026] Please refer specifically to Figure 2 and Figure 3 , the lifting assembly includes a sliding block 14 that is slidably connected up and down inside the plug-in board 10. A sliding groove 13 for the sliding block 14 to slide is formed inside the plug-in board 10. A rotating column 11 is threadedly connected to the inner wall of the sliding block 14. The rotating column 11 penetrates above the plug-in board 10 and extends to the top surface of the connection head 8, and the rotating column 11 is rotatably connected to the connection head 8 and the plug-in board 10.

[0027] In this embodiment: After the plug-in board 10 is docked with the groove on the support frame 6, at this time the connection head 8 is completely located inside the connection groove 7. At this time, a tool is used to dock with the top end of the rotating column 11. The top end of the rotating column 11 has a cross slot or a flat slot. The tool drives the rotating column 11 to rotate. At this time, the sliding block 14 is driven to move up or down under the action of its internal thread. The downward moving sliding block 14 squeezes the squeezing assembly.

[0028] Please refer specifically to Figure 3 Figure 4 , the squeezing assembly includes a limiting plate 12. The limiting plate 12 is axially slidably connected to the lower part inside the plug-in board 10, and square slots for the limiting plate 12 to slide outwards are formed at both ends of the lower part of the plug-in board 10; pressing inclined surfaces 15 are formed at both ends of the lower part of the sliding block 14, and pressing inclined surfaces 16 that coincide with the pressing inclined surfaces 15 are formed at one ends of the two limiting plates 12 that are close to each other.

[0029] In this embodiment: The pressing inclined surface 15 of the downward moving sliding block 14 contacts and presses the pressed inclined surface 16. The pressed inclined surface 16 is forced to drive the two limiting plates 12 to move outwards. The limiting plates 12 move out through the square slots. At this time, the top surface of the limiting plates 12 abuts against the bottom surface of the support frame 6. At this time, the connection head 8 is installed.

[0030] Please refer specifically to Figure 3 and Figure 4 , the reset assembly includes a slider 18 integrally formed with the bottom end of the limiting plate 12. A sliding groove 17 for the slider 18 to slide is formed at the lower part of the inner wall of the plug-in board 10. A partition protruding upwards is formed at the center of the bottom end of the inner wall of the sliding groove 17. A spring 19 is fixedly connected between the partition and the slider 18.

[0031] In this embodiment: When the two limit plates 12 move towards each other, the limit plates 12 drive the sliders 18 to slide along the sliding grooves 17 during the movement. At this time, the spring 19 is stretched. On the contrary, when the rotating column 11 rotates in the reverse direction, as the sliding block 14 moves upward, the spring 19 resets, and the limit plates 12 can be reset to cancel the limit function, and then the filter screen 9 can be taken out for cleaning.

[0032] Please refer specifically to Figure 2 and Figure 3 , the cross-section of the connecting head 8 and the inner wall cross-section of the connecting groove 7 are both in an inverted "convex" shape structure of 180 degrees.

[0033] In this embodiment: With this design method, the connecting groove 7 can support the connecting head 8, and the connecting head 8 can be quickly placed.

[0034] Please refer specifically to Figure 1 , an installation pipe 4 is integrally formed above the outer circumference of the liquid inlet pipe 2 and the liquid outlet pipe 3. The inner cavities of the two installation pipes 4 are respectively communicated with the inner cavities of the liquid inlet pipe 2 and the liquid outlet pipe 3, and hydraulic sensors 5 are installed on the inner walls of the two installation pipes 4.

[0035] In this embodiment: As the filter screen 9 filters, the impurities intercepted inside it gradually increase. At this time, if the liquid inlet peristaltic pump maintains the input pressure, the impurities will be hard-pressed against the filter holes of the filter screen 9 under higher pressure, causing breakage. The broken impurities will enter the lower part of the filter screen 9. By setting two hydraulic sensors 5 to monitor the inlet pressure and the outlet pressure in real time, when the pressure received by the hydraulic sensor 5 sensing the inlet pressure reaches the threshold value, an electric signal is sent to the controller at this time, and the controller controls the liquid inlet peristaltic pump to reduce the input pressure;

[0036] Similarly, after the pressure of the liquid inlet peristaltic pump is reduced, the hydraulic sensor 5 below monitors the discharge pressure of the liquid outlet pipe 3, and the monitored pressure is transmitted to the controller. The controller compares and calculates this signal with the signal transmitted by the hydraulic sensor 5 above to obtain whether the pressure difference between the inlet and the outlet is within the preset range. If the pressure above is smaller and the pressure below is larger, and the difference exceeds the preset range, the controller controls the liquid outlet peristaltic pump to reduce the operating speed to keep the upper and lower pressure differences within the preset range and achieve the constant pressure filtration effect.

[0037] The above-mentioned is only the preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent substitutions or changes, and all should be covered within the protection scope of the present invention.
