Description

Technical Field

[0001] The invention belongs to the technical field of chemical production, in particular to a small reciprocating grease injection pump. Background Art

[0002] The pump body of a small reciprocating grease pump is the core component of the entire equipment, and is usually made of high-strength metal materials such as stainless steel. Its structure is compact and can withstand a certain amount of pressure. The pump body contains key parts such as the piston cavity, inlet and outlet channels, and the piston cavity has good sealing to ensure the normal delivery of grease during the reciprocating motion, and can adapt to the corrosion and wear in the chemical production environment.

[0003] Specifically, the small reciprocating grease pumps commonly found on the market currently have the following shortcomings:

[0004] On the one hand, the grease pump requires a stable placement platform to ensure its normal operation. During daily storage and use, if the placement platform is unstable, the grease pump may shake or shift during operation, which will not only affect the working efficiency of the grease pump, but may also cause damage to its internal structure.

[0005] On the other hand, the impact of dust and other impurities in the working environment on the grease pump cannot be underestimated. Dust and other impurities can easily enter the interior of the grease pump body. Over time, they may accumulate on the key components of the grease pump, interfering with its normal mechanical operation, thereby reducing the performance of the grease pump and shortening its service life.

[0006] In addition, the grease pump may be subject to external collisions during operation or storage. Since the internal structure of the grease pump is relatively precise, rigid collisions may cause irreversible damage to its internal components, thereby affecting the overall performance and service life of the grease pump.

[0036] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0037] A small reciprocating grease injection pump according to an embodiment of the present invention will be described below with reference to the accompanying drawings.

[0038] like Figures 1 to 11 As shown, an embodiment of the present invention provides a small reciprocating grease pump, comprising: an external protection box 1 and a grease pump body 24, the grease pump body 24 is arranged inside the external protection box 1, and also comprises a heat dissipation and ventilation mechanism 51, a pump body fixing and placement mechanism 52 and an operation control mechanism 54, the heat dissipation and ventilation mechanism 51, the pump body fixing and placement mechanism 52 and the operation control mechanism 54 are all arranged in the inner cavity of the external protection box 1, side wall limit mounting plates 47 are respectively provided on both sides of the inner wall of the external protection box 1, the inner cavities of the two side wall limit mounting plates 47 are both provided with internal pull-out auxiliary grooves 50, and circular heat dissipation holes 12 are respectively opened on the side walls on both sides of the external protection box 1.

[0039] The pump body fixing placement mechanism 52 includes an internal partition bearing plate 20, a universal electric telescopic rod 33, an L-shaped auxiliary dustproof baffle 34, an auxiliary connecting rotating shaft 35, an elastic buffer connecting rod 21, a winding buffer spring 22 and a circular fixed connecting rod 38. The two ends of the internal partition bearing plate 20 are arranged inside the internal pull-out auxiliary groove 50, the grease injection pump body 24 is arranged at the top of the internal partition bearing plate 20, the universal electric telescopic rod 33 is arranged at the top of the side wall limit mounting plate 47, the L-shaped auxiliary dustproof baffle 34 is arranged at the telescopic end of the universal electric telescopic rod 33, the top of the L-shaped auxiliary dustproof baffle 34 is fixedly connected to the side wall of the side wall limit mounting plate 47 through the auxiliary connecting rotating shaft 35, the inside of the bottom of the L-shaped auxiliary dustproof baffle 34 is provided with an elastic buffer connecting rod 21, the outer wall of the elastic buffer connecting rod 21 is provided with a matching winding buffer spring 22, and one end of the elastic buffer connecting rod 21 is provided with a circular fixed connecting rod 38, and the material of the circular fixed connecting rod 38 is sponge.

[0040] In a specific application of the embodiment of the present invention, the grease pump body 24 is placed on the internal partition support plate 20, and the two ends of the internal partition support plate 20 are located inside the internal pull-out auxiliary groove 50, so that the internal partition support plate 20 can stably support the grease pump body 24 in the internal pull-out auxiliary groove 50, and it is convenient to adjust the position of the grease pump body 24 as needed, such as pulling out or pushing. Circular heat dissipation holes 12 are provided on the side walls on both sides of the external protective box 1. When the grease pump is working, heat is generated, and the heat can be dissipated through the circular heat dissipation holes 12 to ensure that the grease pump works in a suitable temperature environment to prevent overheating from causing damage to components or reduced work efficiency.

[0041] A universal electric telescopic rod 33 is arranged on the top of the side wall limit mounting plate 47, and its telescopic end is connected to the L-shaped auxiliary dustproof baffle 34. When the grease pump body 24 does not need to be operated, the universal electric telescopic rod 33 can be extended to push the L-shaped auxiliary dustproof baffle 34 to rotate around the auxiliary connection rotating shaft 35, so that the L-shaped auxiliary dustproof baffle 34 covers the top of the grease pump body 24. The elastic buffer connecting rod 21, the winding buffer spring 22 and the circular fixed connecting rod 38 inside the bottom of the L-shaped auxiliary dustproof baffle 34 play the role of auxiliary fixing and buffering. When the L-shaped auxiliary dustproof baffle 34 covers, the circular fixed connecting rod 38 (made of sponge) can gently contact the surface of the grease pump body 24, which not only plays a certain fixing role to prevent the baffle from shaking, but also avoids hard collision with the grease pump body 24, because the sponge material is soft and elastic. At the same time, the winding buffer spring 22 can provide buffering during the contact process to adapt to different contact situations.

[0042] The operation control mechanism 54 can be used to control the working parameter operation of the grease pump body 24, and when the grease pump body 24 needs to be operated, the universal electric telescopic rod 33 can be controlled to retract through the operation control mechanism 54 to remove the L-shaped auxiliary dust baffle 34, thereby facilitating the operation of the grease pump body 24.

[0043] In one embodiment, the heat dissipation and ventilation mechanism 51 includes a filtering heat sink 13, an inner wall placement groove 14, an elastic buffer connecting rod 15, a winding buffer spring 16, an L-shaped auxiliary mounting plate 17, an L-shaped auxiliary mounting plate 2 18 and a fixed connecting pin 19. The filtering heat sink 13 is arranged inside the circular heat dissipation hole 12, and the inner wall placement grooves 14 are respectively arranged on both sides of the side wall of the filtering heat sink 13. The inner wall placement grooves 14 are arranged inside the inner wall placement grooves 14. The outer wall of the elastic buffer connecting rod 15 is provided with a matching winding buffer spring 16. The top of one of the elastic buffer connecting rods 15 is provided with an L-shaped auxiliary mounting plate 17, and the top of the other elastic buffer connecting rod 15 is provided with an L-shaped auxiliary mounting plate 2 18. A fixed connecting pin 19 is arranged between the L-shaped auxiliary mounting plate 17 and the L-shaped auxiliary mounting plate 2 18.

[0044] In the specific application of the embodiment of the present invention, the filtering and heat dissipation plate 13 is arranged inside the circular heat dissipation hole 12, which plays the dual role of filtering and heat dissipation. Its two side walls are provided with inner wall placement grooves 14, which provide space for the installation of subsequent components. An elastic buffer connecting rod 15 is installed inside each inner wall placement groove 14. The elastic buffer connecting rod 15 can be extended and retracted within a certain range during the working process, and its outer wall is provided with a winding buffer spring 16. The function of the winding buffer spring 16 is to provide elastic buffering force.

[0045] An L-shaped auxiliary mounting plate 17 and an L-shaped auxiliary mounting plate 2 18 are respectively arranged at the top of the elastic buffer connecting rod 15. The two L-shaped auxiliary mounting plates are connected by a fixed connecting pin 19, which can make the entire structure more stable and ensure the stability of the filter heat sink 13 during operation. When the heat dissipation and ventilation mechanism 51 is impacted by external force or expands and contracts due to temperature changes, the elastic buffer connecting rod 15 will expand and contract under the action of the winding buffer spring 16. For example, when subjected to an outward impact force, the elastic buffer connecting rod 15 will be compressed, and the winding buffer spring 16 will be compressed to store elastic potential energy, thereby buffering the direct impact of the external force on the filter heat sink 13 and preventing the filter heat sink 13 from being damaged due to excessive external force.

[0046] Similarly, in the case of thermal expansion and contraction, due to the different thermal expansion coefficients of different components, the combination of the elastic buffer connecting rod 15 and the winding buffer spring 16 can allow the filtering heat sink 13 to have a certain expansion and contraction space to ensure the integrity of the entire structure, and the L-shaped auxiliary mounting plate 17 and the L-shaped auxiliary mounting plate 2 18 are connected by a fixed connecting pin 19, which can adapt to such expansion and contraction changes while ensuring a stable connection.

[0047] When the filtering heat sink 13 is working normally, it filters the incoming or outgoing air to prevent dust and other impurities from entering or blocking the heat dissipation channel. At the same time, it also participates in the heat dissipation process. For example, if it is a heat sink in the heat dissipation channel, it will dissipate the heat. The structure composed of the elastic buffer connecting rod 1 15, the winding buffer spring 1 16, the L-shaped auxiliary mounting plate 1 17, the L-shaped auxiliary mounting plate 2 18 and the fixed connecting pin 19 provides a stable working environment for the filtering heat sink 13, ensuring that its filtering and heat dissipation functions can be continuously and effectively performed.

[0048] In one embodiment, the operation control mechanism 54 includes a bottom mounted control box 39, a built-in side wall slot 40, an elastic buffer connecting rod 36, a winding buffer spring 37, a built-in moving block 43, a side connection limit plate 44, a universal electric telescopic rod control button 45 and an auxiliary buffer rod 46. The bottom mounted control box 39 is arranged at the bottom of the side wall limit mounting plate 47, and the inner sides of the inner cavity of the bottom mounted control box 39 are respectively provided with built-in side wall slots 40, and the inner part of the built-in side wall slots 40 is provided with elastic buffer connecting rods. Three 36, the outer wall of the elastic buffer connecting rod three 36 is provided with a matching winding buffer spring three 37, the built-in moving block 43 is arranged inside the bottom mounted control box 39, and the two sides of the built-in moving block 43 are respectively provided with side connecting limit plates 44, the universal electric telescopic rod control button 45 is arranged at one end of the inner cavity of the bottom mounted control box 39, the auxiliary buffer rod 46 is arranged on both sides of the universal electric telescopic rod control button 45, and the universal electric telescopic rod control button 45 is electrically connected to the universal electric telescopic rod 33 through a conductive line.

[0049] In a specific application of the embodiment of the present invention, the universal electric telescopic rod control button 45 is electrically connected to the universal electric telescopic rod 33 through a conductive line. When the universal electric telescopic rod control button 45 is operated, an electrical signal can be sent to the universal electric telescopic rod 33 to control its movement. The bottom mounted control box 39 is located at the bottom of the side wall limit mounting plate 47, and the built-in side wall through grooves 40 opened on both sides of its inner cavity are important structural parts. The elastic buffer connecting rod 3 36 arranged in the built-in side wall through groove 40 and the winding buffer spring 3 37 on its outer wall play a role of buffering and limiting. When an external force acts on the built-in moving block 43, these components can buffer the impact force and limit the excessive movement of the built-in moving block 43.

[0050] The built-in moving block 43 is located inside the bottom mounted control box 39, and the side connecting limit plates 44 on both sides can limit its excessive displacement in the horizontal direction, ensuring its stable movement within a certain range. When the universal electric telescopic rod control button 45 is operated, a certain vibration or reaction force will be generated. The auxiliary buffer rod 46 is located on both sides of the universal electric telescopic rod control button 45, which can buffer the vibration generated when the button is operated. At the same time, the transmission of this vibration or force will affect other components inside the bottom mounted control box 39, such as the built-in moving block 43, but due to the presence of the elastic buffer connecting rod three 36 and the winding buffer spring three 37, the built-in moving block 43 can work in a relatively stable environment.

[0051] Assuming that during the operation of the grease pump, the telescopic action of the universal electric telescopic rod 33 will affect the operating stability of the entire equipment, the various components in the operation control mechanism 54 can ensure the stability of the operation control mechanism 54 itself when controlling the action of the universal electric telescopic rod 33 through the above-mentioned connection and buffering methods, and reduce the interference of the adverse effects of the control operation on the operation of the entire grease pump.

[0052] In one embodiment, a plurality of groups of ventilation and heat dissipation holes 25 of the same size are provided at both ends of the surface of the internal partition supporting plate 20, a pump body placement groove 53 is provided in the middle of the surface of the internal partition supporting plate 20, elastic buffer connecting rods four 41 are provided on both sides of the pump body placement groove 53, the outer wall of the elastic buffer connecting rod four 41 is provided with a matching winding buffer spring four 42, one end of the elastic buffer connecting rod four 41 is provided with a concave clamping fixing plate 23, ferrite magnets one 48 are provided at both ends of one side of the internal partition supporting plate 20, and a matching ferrite magnet two 49 is provided on one side of the inner wall of the internal pull-out auxiliary groove 50.

[0053] In a specific application of the embodiment of the present invention, a plurality of groups of ventilation and heat dissipation holes 25 of the same size are provided at both ends of the surface of the internal partition support plate 20. When the grease pump is working, heat will be generated inside. The ventilation and heat dissipation holes 25 provide a channel for the heat dissipation. The air can convect through these heat dissipation holes to bring out the heat inside the grease pump, thereby preventing the internal temperature from being too high and causing damage to the pump body and other components. The pump body placement groove 53 in the middle of the surface of the internal partition support plate 20 is used to place the pump body. The elastic buffer connecting rods 441 on both sides of the pump body placement groove 53 and the winding buffer springs 442 on its outer wall play an important buffering role. When the grease pump vibrates during operation, the pump body will shake or displace. The elastic buffer connecting rods 441 and the winding buffer springs 442 can absorb the vibration energy and reduce the shaking amplitude of the pump body.

[0054] The concave clamping and fixing plate 23 at one end of the elastic buffer connecting rod 41 can clamp and fix the pump body, and the concave shape can better fit the shape of the pump body and increase the stability of the fixation. When the grease injection pump is working, this fixing method is combined with the buffer structure, which can not only ensure that the pump body is in the normal working position, but also be effectively protected when it is impacted by external forces or self-vibration. The ferrite magnets 1 48 at both ends of one side of the internal partition bearing plate 20 and the ferrite magnets 2 49 on one side of the inner wall of the internal pull-out auxiliary groove 50 cooperate with each other. This magnetic connection method can be used to connect the internal partition bearing plate 20 and other components (such as components related to the internal pull-out auxiliary groove 50). The magnetic connection has the characteristics of convenient installation and disassembly, and can also ensure the tightness of the connection, playing a role in stabilizing the structure and facilitating assembly and maintenance in the overall structure of the grease injection pump.

[0055] In one embodiment, a fixed air guide bottom plate 29 is provided at the bottom of the inner wall of the external protection box body 1, a bottom placement groove 30 is opened inside the fixed air guide bottom plate 29, a chemical waste liquid receiving plate 31 is provided inside the bottom placement groove 30, a fixed connecting handle 10 is provided on the outer wall on one side of the chemical waste liquid receiving plate 31, and a protective pattern is provided on the outer wall of the fixed connecting handle 10, and universal drive motors 26 are respectively provided on both sides of the bottom of the inner wall of the external protection box body 1, and auxiliary threaded connecting plates 27 are provided at the output ends of the two universal drive motors 26, and a plurality of groups of rectangular exhaust fan blades 28 of the same size are provided on the outer walls of the two auxiliary threaded connecting plates 27.

[0056] In the specific application of the embodiment of the present invention, for this small reciprocating grease injection pump, the external protective box 1 plays the role of protecting the internal components, and a fixed air guide bottom plate 29 is set at the bottom of the inner wall of the protective box 1. A groove 30 is placed at the bottom of the fixed air guide bottom plate 29 to place a chemical waste liquid receiving plate 31. The chemical waste liquid receiving plate 31 is used to receive the chemical waste liquid generated during the operation of the grease injection pump (for example, some impurities, residual grease or waste liquid related to the chemical environment will drip onto the receiving plate during the grease injection process). A fixed connection handle 10 is provided on one side of the chemical waste liquid receiving plate 31, and the protective pattern on its outer wall makes it easy for the operator to hold the handle, so as to facilitate the regular cleaning or replacement of the waste liquid receiving plate.

[0057] The output end of the universal drive motor 26 is connected to the auxiliary threaded connecting plate 27, and the outer wall of the auxiliary threaded connecting plate 27 is provided with a plurality of groups of rectangular exhaust fan blades 28 of the same size. When the universal drive motor 26 is started, it drives the auxiliary threaded connecting plate 27 to rotate, so that the rectangular exhaust fan blades 28 start to rotate, and the rotation of the rectangular exhaust fan blades 28 can play a variety of roles. On the one hand, it can form air flow in the protective box, take away the heat generated when the grease injection pump works, and prevent the grease injection pump from malfunctioning or affecting its working performance due to overheating. On the other hand, this air flow helps to keep the air in the protective box dry, and avoids corrosion or damage to the grease injection pump and other components due to environmental factors such as humidity. Moreover, the flow direction of the air can be designed to pass through the chemical waste liquid receiving plate 31, which can accelerate the air flow on the surface of the waste liquid, promote the volatilization of some volatile components in the waste liquid, and reduce the accumulation of odor and harmful gases in the box.

[0058] When the grease pump is working, the universal drive motor 26 drives the exhaust fan blades 28 to maintain a suitable temperature, humidity and air quality environment in the protective box 1. The chemical waste liquid receiving plate 31 receives the waste liquid generated during the operation of the grease pump. The fixed air guide bottom plate 29 at the bottom of the inner wall of the protective box 1 positions and supports the chemical waste liquid receiving plate 31. The various components work together to ensure that the small reciprocating grease pump works in a relatively stable, safe and clean environment.

[0059] In one embodiment, the outer walls on both sides of the external protection box 1 are located above the circular heat dissipation holes 12 and are provided with oblique side protection plates 11, one end of the top of the external protection box 1 is provided with a matching oblique top protection plate 2, and the surface of the top of the external protection box 1 is provided with a matching sloped buffer plate 3.

[0060] The side walls on both sides of the external protection box body 1 are respectively provided with circular side fixing plates 4, and the other side of the circular side fixing plates 4 is provided with a matching L-shaped supporting connecting rod 5, and the bottom end of the L-shaped supporting connecting rod 5 is provided with a matching bottom bearing plate 6, and the bottom of the bottom bearing plate 6 is provided with anti-slip grooves.

[0061] In a specific application of the embodiment of the present invention, a small reciprocating grease pump is placed in an external protective box, and the outer walls on both sides of the external protective box 1 are provided with oblique side protection plates 11 above the circular heat dissipation holes 12, an oblique top protection plate 2 is provided at one end of the top, and an inclined buffer plate 3 is provided on the top surface. The oblique side protection plates 11 can prevent foreign objects or collision forces from the side from directly acting on the area of ​​the external protective box 1 close to the circular heat dissipation holes 12, and avoid blockage or damage to the heat dissipation holes due to accidental collisions, etc. The oblique top protection plate 2 can protect the grease pump and the box at one end of the top, and prevent objects in a specific direction from falling from the top and damaging the equipment or rainwater from directly flowing in. The inclined buffer plate 3 is on the top surface of the box. When an object falls, the inclined buffer plate 3 can make the object slide down the slope, reducing the direct damage to the top of the box by the impact force, thereby protecting the grease pump in the box from interference from physical factors in the external environment.

[0062] The circular side fixing plates 4 on the side walls of the external protection box 1 serve to connect the external protection box 1 and the L-shaped supporting connecting rod 5. The circular side fixing plates 4 cooperate with the L-shaped supporting connecting rod 5. Through this connection method, the L-shaped supporting connecting rod 5 can support the external protection box 1 from the side. The bottom end of the L-shaped supporting connecting rod 5 is connected to the bottom supporting plate 6. The anti-slip grooves on the bottom of the bottom supporting plate 6 increase the friction with the supporting surface, so that when the entire device is placed on the working surface, it can stably support the external protection box 1 and the internal reciprocating grease pump, and prevent shaking, tipping, etc. due to vibrations generated by its own reciprocating motion or external force interference during the operation of the grease pump.

[0063] The circular heat dissipation hole 12 is used to dissipate the heat generated when the grease pump is working, and the oblique side protection plate 11 protects the heat dissipation hole without affecting the heat dissipation (because it is located above the heat dissipation hole), thereby ensuring the normal operation of the heat dissipation function. It takes into account the heat dissipation needs of the grease pump and the protection of heat dissipation-related components, so that the grease pump can work stably in a suitable temperature environment.

[0064] When the grease pump is working, the internal reciprocating parts operate normally, the external protective box 1 and its attached protection and support parts work together, the protective plate prevents external physical damage, the support structure ensures the overall stability, and the heat dissipation holes ensure heat dissipation, so that the grease pump can continuously and stably pump grease according to the law of reciprocating motion.

[0065] In one embodiment, a side inspection door 7 is hinged on the surface of one side of the external protection box 1, and a built-in visual window 8 is provided on the surface of the side inspection door 7. An electrical control operation panel 9 is provided on the surface of the side inspection door 7 below the built-in visual window 8. A fixed connection handle 2 32 is welded on one side of the electrical control operation panel 9 and located on the surface of the side inspection door 7. The outer wall of the fixed connection handle 2 32 is provided with a protective pattern, and the universal drive motor 26 and the universal electric telescopic rod 33 are electrically connected to the electrical control operation panel 9 through conduction lines.

[0066] In the specific application of the embodiment of the present invention, the operation panel 9, the universal drive motor 26 and the universal electric telescopic rod 33 used in the device are all mature existing technologies, and the working principles of the operation panel 9, the universal drive motor 26 and the universal electric telescopic rod 33 are also well known to people in this technical field and will not be described in detail here.

Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.

[0068] The present invention and its embodiments are described above, and such description is not restrictive. The drawings show only one embodiment of the present invention, and the actual structure is not limited thereto. In short, if ordinary technicians in the field are inspired by it, without departing from the purpose of the invention, they can design a structure and embodiment similar to the technical solution without creativity, which should belong to the protection scope of the present invention.
