Description

Technical Field

[0001] This utility model relates to the field of coating device technology, and in particular to an injection pump for coating calcium peptide minerals. Background Technology

[0002] In the research and production of perovskite materials, it is necessary to uniformly coat the perovskite precursor solution onto a substrate to prepare high-quality perovskite films. Existing injection pumps have some shortcomings when used for perovskite coating: their complex structure leads to high costs, their operation is not simple enough, affecting work efficiency, and their compatibility with perovskite precursor solutions and coating precision need improvement, making it difficult to meet the practical needs of scientific research and small-scale production. Utility Model Content

[0003] The purpose of this invention is to provide an injection pump for coating calcium peptide minerals, so as to solve the problems existing in the prior art.

[0004] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0005] An injection pump for coating calcium peptide minerals includes an injection pump and a rectangular frame. The injection pump has at least two observation windows, each with a high-strength transparent cover plate for completely sealing the observation window. The cover plate has graduation lines and is composed of alternating layers of PE film and transparent glass. The bottom inner end of the observation window has a concentric extension edge, which is integrally formed with the injection pump. The rectangular frame is bolted to the outside of the injection pump and is used to cooperate with the extension edge to snap the cover plate into the observation window. Sealing strips are provided at the bottom, periphery, and top of the cover plate.

[0006] By adopting the above technical solution, the outer shell of the injection pump used in this device is made of engineering plastic and the internal structure is a screw drive; the cover plate is composed of a layer of transparent glass and a layer of PE film stacked on top of each other and then laminated. This method makes the cover plate have high transparency and higher pressure resistance.

[0007] In a further embodiment, the top of the rectangular frame is provided with crisscrossing grooves, and the grooves are filled with structural adhesive.

[0008] By adopting the above technical solution, the crisscrossing grooves form a structure similar to reinforcing ribs at the top of the rectangular frame, making its resistance to deformation more prominent and better able to withstand the outward protrusion force of the cover plate. The reason why the cover plate exerts an outward protrusion force on the rectangular frame is that pressure will appear inside the injection pump during use, and this pressure will push the cover plate out. At the same time, in order to avoid the rectangular frame surface being unsightly and difficult to clean, it is filled with structural adhesive.

[0009] In a further embodiment, the scale lines are stickers, and the scale lines are disposed on the outer surface of the cover plate.

[0010] By adopting the above technical solution, the scale lines are set on the outer surface and can be replaced after the scale lines wear out, which facilitates maintenance and maintains the internal cleanliness of the injection pump.

[0011] In a further embodiment, the rectangular frame is made of aluminum alloy.

[0012] In a further embodiment, the syringe pump is provided with a receiving groove for accommodating the rectangular frame at the mounting position, and the outer surface of the rectangular frame is coplanar with the outer surface of the syringe pump.

[0013] By adopting the above technical solution, the inner surface of the injection pump needs to be thickened at the location where the receiving groove is set, which makes the outer surface of the injection pump smoother.

[0014] In summary, this utility model has the following beneficial effects:

[0015] 1. Simple structure: Utilizing an engineering plastic pump body and screw-type drive mechanism, it reduces manufacturing costs and is suitable for small-scale production in research institutions and SMEs. 2. Easy operation: The injection flow rate can be easily adjusted via a speed controller, and the observation window facilitates monitoring of the remaining solution level, lowering the technical barrier for operators. 3. Possesses basic functions such as good solution compatibility and a one-way valve to prevent backflow, meeting common requirements for perovskite coating and ensuring smooth coating operations.

[0021] Example 1:

[0022] like Figures 1-2 As shown, an injection pump for coating calcium peptide minerals includes an injection pump 1 and a rectangular frame 2. The injection pump 1 has at least two observation windows, each with a high-strength transparent cover plate 3 for completely sealing the observation window. The cover plate 3 has scale lines and is composed of alternating layers of PE film and transparent glass. The bottom inner end of the observation window has a concentric extension edge, which is integrally formed with the injection pump 1. The rectangular frame 2 is bolted to the outside of the injection pump 1 and is used to cooperate with the extension edge to snap the cover plate 3 into the observation window. Sealing strips 4 are provided at the bottom, periphery, and top of the cover plate 3. The top of the rectangular frame 2 has crisscrossing grooves filled with structural adhesive. The scale lines are stickers and are located on the outer surface of the cover plate 3. The rectangular frame 2 is made of aluminum alloy. The injection pump 1 has a receiving groove for accommodating the rectangular frame 2, and the outer surface of the rectangular frame 2 is coplanar with the outer surface of the injection pump 1. The cover is made by repeatedly stacking and laminating a layer of transparent glass onto a layer of PE film. This method gives the cover both high transparency and higher pressure resistance.

[0023] Specific implementation process: The present invention aims to provide a practical 380CC injection pump that is simple in structure, easy to operate, low in cost, and can meet the basic requirements of perovskite coating.

[0024] Pump Body Structure Design: The pump body is made of corrosion-resistant engineering plastic, a low-cost material with excellent chemical stability, effectively preventing chemical reactions with the perovskite precursor solution and ensuring solution purity. The pump body's internal design features a smooth cylindrical cavity, facilitating smooth piston movement and reducing frictional resistance. The piston is made of nitrile rubber, which has good oil resistance and chemical stability, and good compatibility with the perovskite precursor solution. The piston surface undergoes a special lubrication treatment to further reduce friction with the pump body's inner wall, ensuring stable solution delivery during injection.

[0025] Drive mechanism: A screw-type drive is adopted. The motor drives the screw to rotate through a reducer. The screw cooperates with a nut mounted on the piston to convert the rotational motion into the linear motion of the piston. This drive method has a simple structure, is easy to manufacture and maintain, and has a relatively low cost. A DC motor is used, equipped with a simple speed controller. The operator can easily adjust the motor speed through the speed controller, thereby controlling the piston's movement speed and achieving preliminary control of the perovskite precursor solution injection flow rate.

[0026] Auxiliary devices: A transparent observation window with clear graduations is installed on the pump body, allowing operators to easily monitor the remaining solution level in the pump and accurately control the injection volume. A one-way valve is installed at the pump outlet to prevent backflow of the perovskite precursor solution, ensuring smooth injection and improving coating stability and accuracy.

[0027] Pump body manufacturing and assembly: Engineering plastics are used to form the pump body shell and internal cavity using injection molding, ensuring dimensional accuracy and surface smoothness. Interfaces for installing an observation window, one-way valve, and drive mechanism are provided on the pump body. The nitrile rubber piston is installed on the matching piston rod, ensuring a tight connection between the piston and piston rod. The piston assembly is then installed into the pump body cavity, and the initial piston position is adjusted.

[0028] Drive mechanism installation: Assemble the DC motor, reducer, and screw together, ensuring coaxiality between the motor and screw. Then, install the assembled drive mechanism onto the pump body using the connecting components, ensuring proper engagement between the screw and the nut on the piston. Connect the motor's power cord and speed controller, and perform initial adjustments to the speed controller to ensure normal motor operation and speed regulation functionality.

[0029] Auxiliary device installation and commissioning: Install the transparent observation window in the corresponding position on the pump body, ensuring the window is well-sealed and the scale is clearly visible. Install the check valve at the pump outlet, check its installation direction and sealing performance, ensuring it functions properly and prevents solution backflow. Perform overall commissioning on the assembled syringe pump, checking the working status of each component to ensure smooth piston movement, normal flow rate regulation, and proper functioning of the observation window and check valve.

Those skilled in the art can understand the specific meaning of the above terms in the embodiments disclosed in this utility model according to the specific circumstances.

[0031] This specific embodiment is merely an explanation of the present utility model and is not intended to limit the present utility model. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but as long as they are within the scope of the claims of the present utility model, they are protected by patent law.
