Description

Technical Field

[0001] This utility model relates to the field of diaphragm pump chambers, specifically a self-cleaning disassembly chamber for removing diaphragm pump processing residues. Background Technology

[0002] In industrial production and many fluid transmission fields, diaphragm pumps play a vital role due to their unique structure and working principle. Diaphragm pumps change the volume of the pump chamber through the reciprocating motion of the diaphragm, thereby realizing the intake and discharge of fluids. They have advantages such as a wide range of transportable media, the ability to transport liquids containing solid particles, and good sealing performance, and are widely used in chemical, pharmaceutical, food, environmental protection and other industries.

[0003] However, in actual use, especially when handling fluids containing viscous substances, solid particles, or easily precipitated substances, traditional diaphragm pumps are prone to leaving processing residues inside the pump chamber. These residues accumulate over time, causing corrosion and wear on the inner wall of the pump chamber, shortening the service life of the diaphragm pump, and affecting the pump's delivery efficiency and accuracy. This leads to problems such as unstable flow and pressure fluctuations, which in turn affect the stability of the entire production process and product quality. Utility Model Content

[0004] Based on this, the purpose of this utility model is to provide a self-cleaning disassembly chamber for diaphragm pumps to remove processing residues. This solves the problem that when traditional diaphragm pumps handle fluids containing viscous substances, solid particles, or easily precipitated substances, processing residues easily remain inside the pump chamber. These residues accumulate over time, causing corrosion and wear on the inner wall of the pump chamber, shortening the service life of the diaphragm pump, and affecting the conveying efficiency and accuracy. This leads to unstable flow and pressure fluctuations, which in turn affect the stability of the entire production process and the quality of the products.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a self-cleaning disassembly chamber for processing residues of a diaphragm pump, comprising a mounting frame and two chambers, wherein a cleaning port is provided at one end of each of the two chambers, and a cleaning mechanism is installed on the cleaning port;

[0006] The cleaning mechanism includes a sealing cover, which is screwed to the cleaning port. The rubber gasket on the inner side of the sealing cover is adapted to the inner diameter of the cleaning port. A connecting pipe is provided at the center of one side of the sealing cover. A water inlet is provided at one end of the connecting pipe. A piston head is provided on the other side of the connecting pipe. A scraper is provided on the inner edge of the piston head, and the scraper abuts against the inner wall of the cavity.

[0007] By adopting the above technical solution, a cleaning port is provided at one end of the cavity and a cleaning mechanism is installed, which provides a basic structure for cleaning, facilitates the subsequent cleaning of processing residues in the cavity, and ensures the stable operation of the diaphragm pump.

[0008] Furthermore, a mounting groove is provided in the middle of the inner side of the piston head, and multiple water spray heads arranged in a ring array are installed in the mounting groove.

[0009] By adopting the above technical solution, an installation groove is opened in the middle of the inner side of the piston head and multiple water spray heads are installed in a ring array, which can evenly spray water onto the inner wall of the cavity to assist in cleaning and improve the cleaning effect on the residue on the inner wall of the cavity.

[0010] Furthermore, a pump body is provided at the top center of the mounting frame, and cavities are provided at the top, bottom and sides of the pump body. The outer surfaces of the two cavities are respectively provided with an inlet and an outlet.

[0011] By adopting the above technical solution, the pump body is located in the middle of the top of the mounting frame, and there are cavities at the top, bottom and sides of the pump body. The outer surface of the cavity has a feed inlet and a discharge outlet. The reasonable layout realizes fluid transportation and meets the basic functions of the diaphragm pump.

[0012] Furthermore, the spray direction of the water nozzle is towards the inner wall of the cavity.

[0013] By adopting the above technical solution, the water spray head is directed towards the inner wall of the cavity, ensuring that the water flow directly acts on the inner wall, effectively flushing away residues, improving cleaning efficiency, and enhancing the cleaning effect on the inner wall of the cavity.

[0014] Furthermore, the piston head is configured to reciprocate along the inner wall of the cavity, and the scraper moves with the piston head to scrape off residue.

[0015] By adopting the above technical solution, the piston head can reciprocate along the inner wall of the cavity, and the scraper blade scrapes away the residue as it moves, which can thoroughly clean the inner wall of the cavity, effectively solve the problem of residue accumulation, and ensure stable production.

[0016] Furthermore, the spray paths of the multiple water nozzles cover the annular area in front of the piston head.

[0017] By adopting the above technical solution, the spray paths of multiple water nozzles cover the annular area in front of the piston head, expanding the cleaning range, ensuring that there is no residue in the area in front of the piston head, and improving the overall cleaning effect.

[0018] Furthermore, the scraper is made of an elastic material to maintain contact with the inner wall of the cavity.

[0019] By adopting the above technical solution, the scraper is made of elastic material, which can maintain contact with the inner wall of the cavity, effectively scrape off residues, adapt to the inner wall in different conditions, and improve cleaning reliability.

[0020] In summary, the present invention has the following main advantages:

[0021] 1. This utility model features a piston head with a scraper and a loosely connected sealing cap. The scraper is made of elastic material to maintain contact with the inner wall of the cavity. When cleaning the cavity is required, the sealing cap is loosened, and the sealing cap moves outward along with the piston head through the connecting pipe. During this process, the scraper can directly scrape off the processing residue remaining on the inner wall of the cavity, solving the problem that residues in the pump cavity of traditional diaphragm pumps are difficult to remove effectively by conventional methods. The accumulation of residues will corrode and wear the inner wall of the pump cavity, affecting the conveying efficiency and accuracy, and thus affecting the stability of the production process and product quality.

[0022] 2. This utility model involves creating an installation groove in the middle of the inner side of the piston head and installing multiple water spray heads arranged in a circular array with their spray direction facing the inner wall of the cavity. The spray paths of these multiple water spray heads cover the annular area in front of the piston head. When the sealing cover is loosened to move the piston head outward for cleaning, the water spray heads spray water simultaneously. The water flow, combined with the scraping action of the scraper, can more efficiently and thoroughly remove residues from the inner wall of the cavity, solving the problem that traditional cleaning methods are unable to thoroughly clean residues in hidden parts of the pump cavity.

[0028] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0029] A self-cleaning disassembly chamber for processing residues in a diaphragm pump, such as Figure 1-4As shown, it includes a mounting bracket 1 and two cavities 2. One end of each cavity 2 is provided with a cleaning port 5, and a cleaning mechanism 7 is installed on the cleaning port 5.

[0030] The cleaning mechanism 7 includes a sealing cover 701, which is screwed onto the cleaning port 5. The rubber gasket inside the sealing cover 701 is compatible with the inner diameter of the cleaning port 5. A connecting pipe 702 is located at the axial center of one side of the sealing cover 701. One end of the connecting pipe 702 has a water inlet 703, and the other side has a piston head 704. A scraper 705 is located on the inner edge of the piston head 704, and the scraper 705 abuts against the inner wall of the cavity 2. The mounting bracket 1 and the two cavities 2 provide a stable support frame for the entire diaphragm pump. The cleaning port 5 at one end of each of the two cavities 2, where the cleaning mechanism 7 is installed, provides a dedicated inlet and operating component for cleaning processing residues inside the cavities 2, providing a foundation for subsequent cleaning work and ensuring the long-term stable operation of the diaphragm pump.

[0031] See Figure 1 , Figure 4 The piston head 704 has a mounting groove 706 in the middle of its inner side. Multiple water spray heads 707 arranged in a circular array are installed in the mounting groove 706. This structural design allows the water spray heads 707 to evenly spray water onto the inner wall of the cavity 2 during cleaning. The circular array arrangement of the multiple water spray heads 707 ensures the coverage of the water spray, effectively assisting other cleaning components and improving the cleaning effect on residues on the inner wall of the cavity 2.

[0032] See Figure 3 , Figure 4 The pump body 6 is located at the top center of the mounting frame 1, and cavities 2 are located at the top, bottom, and sides of the pump body 6. The outer surfaces of the two cavities 2 are respectively provided with inlet 3 and outlet 4. This layout makes full use of space. The inlet 3 and outlet 4 on the outer surfaces of the cavities 2 provide channels for fluid input and output. This reasonable structural layout enables the diaphragm pump to smoothly transport fluid and meet its basic functional requirements.

[0033] See Figure 1 , Figure 2 The water spray head 707 is directed towards the inner wall of the cavity 2. This design allows the water flow to directly act on the inner wall of the cavity 2 during the cleaning process. This effectively washes away processing residues on the inner wall, avoids water waste and ineffective spraying, improves cleaning efficiency, and enhances the overall cleaning effect of the structure on the inner wall of the cavity 2.

[0034] See Figure 4 The piston head 704 is configured to reciprocate along the inner wall of the cavity 2. The scraper 705 moves with the piston head 704 to scrape away residue. This movement allows the scraper 705 to thoroughly clean the inner wall of the cavity 2, covering every part of the inner wall, effectively solving the problem of residue accumulation and ensuring production stability and product quality.

[0035] See Figure 3 , Figure 4 The spray paths of multiple water nozzles 707 cover the annular area in front of the piston head 704, thus expanding the cleaning range. During the cleaning process, the annular area in front of the piston head 704 is covered by water flow, ensuring no residue remains in this area and improving the overall cleaning effect of the entire structure on the inner wall of the cavity 2.

[0036] See Figure 1 The scraper blade 705 is made of an elastic material to maintain contact with the inner wall of the cavity 2. The properties of the elastic material allow the scraper blade 705 to adapt to different conditions of the inner wall of the cavity 2. Whether it is a minor deformation of the inner wall or an uneven surface, it can maintain a tight contact, thereby effectively scraping away residues and improving the reliability and stability of cleaning.

[0037] The implementation principle of this embodiment is as follows: First, when the diaphragm pump is in normal use, the mounting frame 1 provides a stable support structure for the pump body 6 and the two cavities 2. The inlet 3 and outlet 4 on the cavity 2 are used for fluid input and output, respectively, thereby realizing the basic function of the diaphragm pump.

[0038] When cleaning of processing residues inside cavity 2 is required, the sealing cover 701 is screwed to the cleaning port 5, and the rubber gasket on the inner side of the sealing cover 701 is compatible with the inner diameter of the cleaning port 5, ensuring a good seal. Loosening the sealing cover 701 at this time allows the connecting pipe 702, located at the axial center of one side of the sealing cover 701, and the piston head 704 on the other side, to move the sealing cover 701 outward via the connecting pipe 702. The piston head 704 has a scraper 705 made of elastic material on its inner edge, which abuts against the inner wall of cavity 2. During the movement of the piston head 704, the scraper 705 directly scrapes away the processing residues remaining on the inner wall of cavity 2, effectively solving the problem that residues in the pump cavity of traditional diaphragm pumps are difficult to remove using conventional methods. The accumulation of residues corrodes and wears the inner wall of the pump cavity, affecting conveying efficiency and accuracy, and consequently impacting production process stability and product quality.

[0039] Meanwhile, an installation groove 706 is provided in the middle of the inner side of the piston head 704. Multiple water spray heads 707 arranged in a ring array and spraying direction toward the inner wall of the cavity 2 are installed in the installation groove 706. The spray path of the multiple water spray heads 707 covers the ring area in front of the piston head 704.

[0040] When the piston head 704 is moved outward by loosening the sealing cover 701 for cleaning, water is injected into the connecting pipe 702 through the water inlet 703. The water flows through the connecting pipe 702 and is sprayed out from the spray head 707. In conjunction with the scraping action of the scraper 705, the residue on the inner wall of the cavity 2 can be removed more efficiently and thoroughly, solving the problem that traditional cleaning methods are unable to thoroughly clean the residue in the hidden parts of the pump cavity.
