Description

Technical Field

[0002] The plunger pump is an important device in the hydraulic system. It mainly relies on the reciprocating motion of the plunger rod in the plunger barrel to change the volume in the sealed chamber to achieve liquid suction and discharge. At present, plunger pumps are often used in beverage and dairy production equipment for liquid transportation and filling operations.

[0003] In order to meet the cleanliness requirements of beverages, dairy products and other beverages, the plunger barrel of the plunger pump currently used in beverage production equipment is mainly made of stainless steel. During the operation of the plunger pump, due to the limited flatness of the inner wall of the plunger barrel, the plunger rod and the inner wall of the plunger barrel will continue to rub for a long time, resulting in poor sealing of the inner cavity of the plunger pump. In addition, due to the good thermal conductivity of stainless steel, the cold drink inside will cause the outer wall temperature of the plunger barrel to be lower than the indoor temperature, thereby generating condensed water on the outer wall of the plunger barrel. The condensed water will drip into the product as the equipment runs, affecting the product quality and taste. Utility Model Content

In this way, when the plunger pump is working, the friction between the plunger rod and the plunger barrel can be reduced, the service life of the plunger barrel can be extended, and when the inner liner is severely worn, the inner liner can be easily replaced. Moreover, by replacing the single-layer plunger barrel in the related art with the double-layer plunger barrel in this embodiment, the inner liner can be used to play a certain heat insulation role.

[0034] In order to make the above-mentioned purposes, features and advantages of the embodiments of the present application more obvious and understandable, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work belong to the scope of protection of this application.

[0035] The plunger pump is an important device in the hydraulic system. It mainly relies on the reciprocating motion of the plunger rod in the plunger barrel to change the volume in the sealed chamber to achieve liquid suction and discharge. At present, plunger pumps are often used in the production equipment of beverages such as beverages and dairy products for the transportation and filling of liquids. In order to meet the cleanliness requirements of production equipment for beverages such as beverages and dairy products, the plunger pumps currently used in beverage production equipment mainly use stainless steel as the plunger barrel. During the operation of the plunger pump, due to the limited flatness of the inner wall of the plunger barrel, the plunger rod and the inner wall of the plunger barrel will continue to rub for a long time, resulting in poor sealing of the inner cavity of the plunger pump. In addition, due to the good thermal conductivity of stainless steel, the cold drink inside will cause the outer wall temperature of the plunger barrel to be lower than the indoor temperature, thereby generating condensed water on the outer wall of the plunger barrel. The condensed water will drip into the product as the equipment runs, affecting the product quality and taste.

[0036] In view of this, the utility model provides a plunger barrel, a plunger pump and production equipment, in which the inner liner as a wear-resistant part is detachably embedded in the inner side of the outer barrel, and the inner liner and the outer barrel are limitedly matched by a limit structure and a limit matching structure, so that when the plunger pump is working, the friction between the plunger rod and the plunger barrel can be reduced, the service life of the plunger barrel can be extended, and when the inner liner is severely worn, the inner liner can be easily replaced. Moreover, by replacing the single-layer plunger barrel of the related technology with the double-layer plunger barrel in this embodiment, the inner liner can be used to play a certain heat insulation role. In this way, when the plunger pump is used for the production of cold drinks, it can prevent the cold drink in the plunger barrel from absorbing the heat of the outer barrel and causing condensation water to be generated on the outer barrel, thereby preventing the condensation water from flowing into the product and affecting the product quality.

[0037] Reference below Figure 1-Figure 5 A plunger cartridge 10 according to an embodiment of the present invention is described.

[0038] Combination Figure 1-Figure 3 The plunger barrel 10 of this embodiment is used for a plunger pump 100. The plunger pump 100 may include a plunger barrel 10 and a plunger rod 20, wherein the plunger rod 20 is adapted to move along the axial direction of the plunger barrel 10, and a sealing ring (not shown) is provided between the plunger rod 20 and the plunger barrel 10. For example, the sealing ring may be sleeved on the outer side of the plunger rod 20 to ensure the sealing between the plunger rod 20 and the plunger barrel 10.

[0039] Among them, combined Figure 4 and Figure 5The plunger cylinder 10 may include: an outer cylinder 11 and an inner liner 12. The outer cylinder 11 has an inner cavity with openings at both ends. For example, the outer cylinder 11 is a cylindrical shape with openings at both ends. The inner liner 12 is embedded in the inner side of the outer cylinder 11. The inner liner 12 is a wear-resistant part. For example, the inner liner 12 may be a cylindrical structural part with a wear-resistant coating on the surface; or, the inner liner 12 is made of a wear-resistant material as a whole. The inner liner 12 and the outer cylinder 11 may be detachably matched. In this way, after the inner liner 12 is worn to a certain extent, the inner liner 12 can be disassembled and replaced.

[0040] Since the liner 12 and the outer tube 11 are detachably matched, and there is friction between the liner 12 and the plunger rod 20 of the plunger pump 100 during the operation of the plunger pump 100, in order to prevent the liner 12 from moving relative to the outer tube 11 with the plunger rod 20, the position of the liner 12 is ensured to be stable. In this embodiment, one of the liner 12 and the outer tube 11 is provided with a limiting structure 111, and the other is provided with a limiting matching structure 121. The limiting structure 111 is limitedly matched with the limiting matching structure 121. For example, the limiting structure 111 can be a groove structure, a hole structure, a buckle structure, etc., and the limiting matching structure 121 can be a protruding structure, a plug-in structure adapted to the groove structure or the hole structure, or a snap-fit ​​structure matched with the buckle structure, etc.

[0041] It can be understood that the liner 12 can be used as a wear-resistant part to provide a low-resistance movement environment for the plunger rod 20 and reduce the wear on the sealing ring and the liner 12, and can also be used as a heat insulating part to insulate the outer tube 11.

[0042] According to the plunger barrel 10 of the embodiment of the utility model, the inner liner 12 as a wear-resistant part is detachably embedded in the inner side of the outer barrel 11, and the inner liner 12 and the outer barrel 11 are limited and matched by the limiting structure 111 and the limiting matching structure 121. In this way, when the plunger pump 100 is working, the friction between the plunger rod 20 and the plunger barrel 10 can be reduced, and the service life of the plunger barrel 10 can be extended. In addition, when the inner liner 12 is severely worn, the inner liner 12 can be easily replaced. Moreover, by replacing the single-layer plunger barrel 10 of the related art with the double-layer plunger barrel 10 in this embodiment, the inner liner 12 can be used to play a certain heat insulation role. In this way, when the plunger pump 100 is used for the production of cold drinks, it can prevent the cold drink in the plunger barrel 10 from absorbing the heat of the outer barrel 11 and causing condensation water to be generated on the outer barrel 11, thereby preventing the condensation water from flowing into the product and affecting the product quality.

[0043] In some embodiments, the lining 12 may be a ceramic part. In this way, the lining 12 has good wear resistance. In addition, it can also play a good heat insulation role, thereby preventing heat transfer between the inside and outside of the plunger barrel 10.

[0044] In some embodiments, the outer cylinder 11 may be a metal part. For example, the outer cylinder 11 may be stainless steel, such as 316 stainless steel, so that the outer cylinder 11 has sufficient strength to better support the liner 12 and the plunger rod 20 and withstand a certain pressure, thereby improving the reliability of the plunger pump 100.

[0045] In summary, the outer cylinder 11 of the metal part can provide bump protection for the inner lining 12 of the ceramic part, ensuring that external impact will not cause damage to the inner lining 12. The inner lining 12 can provide a low-resistance environment for the movement of the plunger rod 20, reducing the wear of the sealing ring on the plunger rod 20 and the plunger cylinder 10, while isolating the internal liquid from the outer cylinder to prevent condensation water from forming on the surface of the outer cylinder 11.

[0046] In some embodiments, in combination Figure 4 and Figure 5 The side wall of the outer cylinder 11 is formed with a limiting groove, and the limiting groove constitutes a limiting structure 111. The limiting groove can penetrate the side wall of the outer cylinder 11 along the radial direction of the outer cylinder 11, or can also be formed by the inner wall of the outer cylinder 11 being recessed outward. The side wall (i.e., the outer wall) of the liner 12 is provided with a limiting protrusion, and the limiting protrusion constitutes a limiting matching structure 121. In this way, when the liner 12 and the outer cylinder 11 are assembled, the limiting protrusion can be inserted into the limiting groove, thereby realizing the limiting matching of the outer cylinder 11 and the liner 12, ensuring the stable position of the liner 12 during the operation of the plunger pump 100. In addition, the matching structure of the outer cylinder 11 and the liner 12 is relatively simple, and easy to manufacture and assemble.

[0047] In some embodiments, the limiting groove may include a first section and a second section. The first section extends along the axial direction of the outer cylinder 11, and an angle is formed between the second section and the first section, and the angle is 90°-135°. For example, the angle may be 90°, 100°, 110°, 120°, 130°, or 135°. Of course, the utility model does not limit this, and the angle between the second section and the first section may be reasonably selected within the above range according to actual needs. When the angle is greater than 90°, the second section may extend obliquely toward a side away from the first section relative to the radial direction of the outer cylinder 11, and when the angle is 90°, the second section and the first section may be perpendicular to each other. In this way, the structure of the limiting groove is more diverse and easy to implement, and the first section may limit the limiting protrusion in the circumferential direction, and the second section may achieve a certain limiting effect on the limiting protrusion in the axial direction.

[0048] In some embodiments, the second section extends along the circumference of the outer cylinder 11. That is, the angle between the second section and the first section is 90°, so that the first section can limit the limiting protrusion in the circumferential direction, and the second section can limit the limiting protrusion in the axial direction, and the overall structure of the limiting groove is relatively simple and easy to implement.

[0049] In some embodiments, in combination Figure 4 and Figure 5 At least one positioning structure 112 is provided on the circumference of one end of the outer cylinder 11 provided with the limiting structure 111, and at least one positioning matching structure 122 is provided on the circumference of one end of the liner 12 provided with the limiting matching structure 121. For example, the positioning structure 112 and the positioning matching structure 122 can both be positioning grooves. In this way, when the liner 12 and the outer cylinder 11 are assembled, when the limiting matching structure 121 enters the limiting structure 111 and any one of the positioning structures 112 is aligned with the positioning matching structure 122, it means that the liner 12 has been installed in place.

[0050] In some embodiments, in combination Figure 4 and Figure 5 , a connection structure 113 is provided at one end of the outer cylinder 11 along the axial direction, and the connection structure 113 is configured to be connected to the mounting bracket 200 of the production equipment 400. For example, a mounting port 2011 may be provided on the mounting bracket 200, and one end of the outer cylinder 11 provided with the connection structure 113 may be inserted into the mounting port 2011, and the connection structure 113 may be connected with a thread, and the inner wall of the mounting port 2011 may be provided with a matching thread, so that the outer cylinder 11 and the mounting bracket 200 are threadedly connected. Of course, the utility model is not limited to this, and the connection structure 113 can be designed according to the specific structure of the mounting bracket 200 of the production equipment 400. In this way, the installation of the plunger pump 100 on the production equipment 400 can be facilitated.

[0051] Optional, combined Figure 4 and Figure 5 Since the plunger tube 10 will be subjected to a certain pressure when the plunger rod 20 moves axially relative to the plunger tube 10 and toward the mounting bracket 200, in order to make the installation of the plunger tube 10 on the mounting bracket 200 more stable, an abutting boss 114 can be provided on the side of the connecting structure 113 facing away from the mounting bracket 200. The abutting boss 114 can abut against the upper surface of the mounting bracket 200. The abutting boss 114 can be formed into a ring extending along the circumference of the outer tube 11, or can be formed into an arc segment. In this way, the mounting bracket 200 can better support the plunger tube 10 and prevent the plunger tube 10 from swinging.

[0052] The following describes a plunger pump 100 according to a second embodiment of the present invention.

[0053] Combination Figure 1-Figure 5 The plunger pump 100 of this embodiment may include: the plunger barrel 10 and the plunger rod 20 in the above embodiment. Specifically, the plunger rod 20 is arranged on the inner side of the liner 12 and is suitable for axial movement along the outer barrel 11 relative to the liner 12. Through the movement of the plunger rod 20 relative to the liner 12, the suction and discharge of the feed liquid can be achieved.

[0054] According to the plunger pump 100 of the embodiment of the utility model, by providing the plunger barrel 10 in the above embodiment, the friction between the plunger rod 20 and the plunger barrel 10 can be reduced, the service life of the plunger barrel 10 can be extended, and when the liner 12 is severely worn, the liner 12 can be easily replaced. Moreover, by replacing the single-layer plunger barrel 10 of the related art with the double-layer plunger barrel 10 in this embodiment, the liner 12 can be used to play a certain heat insulation role. In this way, when the plunger pump 100 is used for the production of cold drinks, the cold drink in the plunger barrel 10 can be prevented from absorbing the heat of the outer barrel 11 and causing condensation water to be generated on the outer barrel 11, thereby preventing the condensation water from flowing into the product and affecting the product quality.

[0055] Combine the following Figure 1-Figure 5 The production equipment 400 according to the third aspect of the embodiment of the utility model is described.

[0056] The production equipment 400 of this embodiment may be a filling equipment or other intermediate process equipment for food such as beverages and dairy products. The production equipment 400 may include: a mounting bracket 200 and the plunger pump 100 in the above embodiment.

[0057] Specifically, combined Figure 1-Figure 3 The mounting bracket 200 may include a bracket body 201 and an adjusting member 202. The cross section of the bracket body 201 may be square, circular or other shapes. Taking the bracket body 201 having a square cross section as an example, the bracket body 201 may define a perfusion cavity, and the perfusion cavity extends along the long side direction of the bracket body 201.

[0058] The support body 201 includes a first side surface, a second side surface, a third side surface and a fourth side surface arranged in sequence along its circumference. The first side surface is provided with a plurality of mounting ports 2011 connected to the perfusion cavity, and the plurality of mounting ports 2011 are arranged along the long side direction of the support body 201, for example, arranged at intervals. The second side surface is provided with a plurality of suction ports 2012 connected to the perfusion cavity, and the plurality of suction ports 2012 are arranged along the long side direction of the support body 201. The suction ports 2012 are used to connect to a feeding device, and the feeding device may store cold drinks such as beverages, dairy products, ice cream, or other foods. The third side surface is provided with a plurality of filling ports 2013 connected to the perfusion cavity, and the plurality of filling ports 2013 are arranged along the long side direction of the support body 201.

[0059] The infusion port 2013, the suction port 2012 and the installation port 2011 are all in one-to-one correspondence with each other. At least part of the structure of the adjusting member 202 is movably arranged in the infusion cavity, and the adjusting member 202 is used to connect the infusion cavity with one of the suction port 2012 and the infusion port 2013. For example, the adjusting member 202 can rotate between a first position and a second position along the circumference of the support body 201. When the adjusting member 202 rotates to the first position, the infusion cavity is connected with the suction port 2012. When the adjusting member 202 rotates to the second position, the infusion cavity is connected with the infusion port 2013. Alternatively, the adjusting member 202 can also perform translational motion along the length direction of the support body 201. In other words, the adjusting member 202 can open and close any one of the suction port 2012 and the infusion port 2013.

[0060] There are multiple plunger pumps 100 corresponding one to one with the mounting ports 2011. The outer tube 11 of the plunger pump 100 is arranged at the corresponding mounting port 2011 and is fixedly connected to the mounting bracket 200. Specifically, a connecting structure 113 can be provided at one end of the outer tube 11 of the plunger pump 100 facing the bracket body 201. The connecting structure 113 can be a connecting thread. The outer tube 11 is inserted into the mounting port 2011 and is threadedly matched with the bracket body 201.

[0061] The working principle of the production equipment 400 of this embodiment is as follows: the movement of the regulating member 202 is controlled so that the suction port 2012 and the infusion chamber are connected, and the infusion chamber and the infusion port 2013 are isolated, and the plunger rod 20 in the plunger pump 100 moves outward along the axial direction of the plunger barrel 10, and the material in the feeding device is drawn into the infusion chamber through the suction port 2012; then the movement of the regulating member 202 is controlled so that the infusion port 2013 and the infusion chamber are connected, and the suction port 2012 and the infusion chamber are isolated, and the plunger rod 20 in the plunger pump 100 moves inward along the axial direction of the plunger barrel 10, and the material in the infusion chamber is infused into the external container through the infusion port 2013. The external container can be a food container or food packaging such as a cup or bowl, thereby completing the food infusion production.

[0062] According to the production equipment 400 of the embodiment of the utility model, the infusion production of foods such as beverages and dairy products can be reliably realized, and large-scale production can be realized. In addition, since the inner lining 12 of the plunger cylinder 10 plays a certain heat insulating role, during the production process, it can prevent the cold drink in the plunger cylinder 10 from absorbing the heat of the outer cylinder 11 and causing condensation water to be generated on the outer cylinder 11, thereby preventing the condensation water from flowing into the product and affecting the product quality.

[0063] In some embodiments, the production equipment 400 may further include a discharge nozzle 300. Specifically, there are multiple discharge nozzles 300 corresponding to the filling ports 2013, and the discharge nozzles 300 are arranged at the corresponding filling ports 2013. The discharge nozzles 300 can guide food and beverages into an external container to prevent splashing of the liquid, which is conducive to better filling.
