Description

Technical Field

[0001] This utility model belongs to the technical field of water treatment equipment accessories, specifically relating to an adjustable filter head. Background Technology

[0002] Backwashing is the most critical step in filter operation, and the water and air distribution system is essential for ensuring its successful implementation. Current technology lacks adjustable filter head height. Filter heads consist of filter rods and embedded bases. The inability to adjust the filter head height means the position of the filter rods relative to the embedded base cannot be adjusted. This necessitates the use of cumbersome and complex prefabricated templates with precise horizontal alignment requirements, which is not only labor-intensive and time-consuming but also costly. Utility Model Content

[0003] This invention provides an adjustable filter head, which aims to solve the problem that the position of the filter head pre-embedded seat relative to the filter rod cannot be adjusted in the prior art.

[0004] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0005] An adjustable filter head includes a filter rod, the upper end of which is provided with a filter head embedding seat, and a filter cap is provided on the filter head embedding seat;

[0006] The filter rod is threaded onto the filter head pre-embedded seat. The filter rod has an external thread, and the filter head pre-embedded seat has an internal thread that mates with the external thread on the filter rod. The filter head pre-embedded seat is cylindrical and is coaxially arranged with the filter rod.

[0007] An anti-loosening component is provided between the filter head pre-embedded seat and the filter rod to prevent the filter rod from rotating accidentally relative to the filter head pre-embedded seat.

[0008] A further improved solution: The anti-loosening component includes an anti-loosening cylinder, the lower end of which abuts against the upper end of the filter rod, and the anti-loosening cylinder is threaded onto the filter head pre-embedded seat.

[0009] Based on the above technical solution: the anti-loosening sleeve is threaded onto the filter head pre-embedded seat, with its lower end abutting against the upper end of the filter rod. During normal operation of the filter, water and air flow will generate impact forces on the filter rod in various directions, which tend to cause the filter rod to rotate. The presence of the anti-loosening sleeve increases the resistance to the rotation of the filter rod. When the filter rod tends to rotate, the friction between the anti-loosening sleeve and the upper end of the filter rod, as well as the connection between the anti-loosening sleeve and the filter head pre-embedded seat through the thread, will prevent the filter rod from rotating, thus ensuring the stability of the filter rod's position relative to the filter head pre-embedded seat. This ensures that the filter head height will not change arbitrarily due to external factors, maintaining the stability of the filter's backwashing effect. The anti-loosening sleeve and the filter head pre-embedded seat are connected by threads, and this connection method forms a relatively stable integrated structure between the anti-loosening sleeve, the filter head pre-embedded seat, and the filter rod. Under the vibration and impact environment of the filter operation, this stable structure can better withstand external forces, reduce loosening and displacement between various components, improve the structural strength and reliability of the entire adjustable filter head, and extend its service life.

[0010] A further improved solution: the anti-loosening cylinder is provided with an external thread, and the filter head pre-embedded seat is also provided with an internal thread that mates with the external thread on the anti-loosening cylinder.

[0011] Based on the above technical solution: the anti-loosening sleeve has an external thread, and the filter head pre-embedded seat has a matching internal thread. This threaded connection provides a precise and reliable connection mechanism to prevent the filter rod from rotating accidentally. After the filter rod is adjusted to the appropriate height, the anti-loosening sleeve is screwed into the filter head pre-embedded seat through the thread. As the anti-loosening sleeve is screwed in, its lower end gradually presses tightly against the upper end of the filter rod. The precise thread fit allows the anti-loosening sleeve to be stably fixed on the filter head pre-embedded seat, thereby generating continuous and stable pressure on the filter rod, effectively preventing the filter rod from rotating under the action of external forces such as water flow and airflow, ensuring that the filter head height always remains at the set value, and guaranteeing the stability and consistency of the filter tank backwashing effect. This threaded connection design makes the installation and removal of the anti-loosening sleeve very flexible. When it is necessary to adjust the filter head height, the anti-loosening sleeve can be unscrewed from the filter head pre-embedded seat to release the filter rod, and then the filter rod can be rotated to adjust the height. After adjustment, the anti-loosening sleeve is screwed back into the filter head pre-embedded seat, so that its lower end presses against the upper end of the filter rod to complete the fixation. The entire process is simple and convenient, requiring no complicated tools or professional skills. It can quickly adjust and fix the height of the filter head, improving work efficiency and reducing operational difficulty and cost.

[0012] A further improved solution: An anti-loosening spring is also provided between the anti-loosening cylinder and the filter head pre-embedded seat to prevent the anti-loosening cylinder from rotating erroneously relative to the filter head pre-embedded seat.

[0013] Based on the above technical solution: the threaded connection between the anti-loosening cylinder and the filter head pre-embedded seat already provides a certain degree of anti-loosening capability, while the addition of the anti-loosening spring forms a double anti-loosening mechanism. During the operation of the filter bed, the impact force generated by water flow and airflow may cause the anti-loosening cylinder to tend to rotate. At this time, the anti-loosening spring will exert a reverse resistance on the anti-loosening cylinder with its own elastic force, preventing it from rotating relative to the filter head pre-embedded seat. This double anti-loosening guarantee greatly improves the stability of the filter rod position, ensuring that the filter head height will not easily change due to external factors, thereby ensuring the stable and reliable backwashing effect of the filter bed.

[0014] A further improved solution: The anti-loosening cylinder includes a cylinder body and a positioning ring disposed on the cylinder body. The cylinder body and the positioning ring are an integral structure. The diameter of the cylinder body is smaller than the diameter of the positioning ring. The cylinder body and the positioning ring are coaxially arranged. The external thread on the anti-loosening cylinder is disposed on the positioning ring.

[0015] Based on the above technical solution, the cylinder and positioning ring adopt an integrated structural design, which greatly enhances the overall structural strength of the anti-loosening cylinder. During the operation of the filter, the anti-loosening cylinder is subjected to various forces from the filter rod and external water flow, airflow, etc. The integrated structure can effectively prevent loosening or separation between the cylinder and positioning ring due to weak connection, ensuring that the anti-loosening cylinder always maintains a stable structural shape, thus more reliably performing its anti-loosening function.

[0016] A further improved solution: The filter head pre-embedded seat is also provided with a connecting ring that cooperates with the filter rod. The connecting ring and the filter head pre-embedded seat are an integral structure. The internal thread on the filter head pre-embedded seat that cooperates with the external thread on the filter rod is provided on the connecting ring.

[0017] Based on the above technical solution: the connecting ring and the filter head pre-embedded seat adopt an integrated structure, which significantly improves the overall structural stability. During the operation of the filter tank, the filter rod is subjected to various dynamic forces such as water flow, air flow, and backwashing, which are transmitted to the filter head pre-embedded seat through the filter rod. The integrated connecting ring and filter head pre-embedded seat can better withstand these forces, avoiding structural failure caused by loosening or separation of the connection parts. When installing the filter rod, the operator can accurately align the external thread of the filter rod with the internal thread on the connecting ring, and then rotate it for installation. Since the size and position of the connecting ring are relatively fixed, this positioning method can ensure the installation accuracy of the filter rod, enabling the filter rod to accurately reach the designed height and position, ensuring the filtration and backwashing effects of the filter head.

[0018] A further improved solution: the connecting ring is coaxially arranged with the filter head pre-embedded seat, the upper end of the anti-loosening spring contacts the lower end of the positioning ring, and the lower end of the anti-loosening spring contacts the upper end of the connecting ring.

[0019] Based on the above technical solution, the connecting ring and the filter head pre-embedded seat are coaxially arranged, laying a precise axial positioning foundation for the entire adjustable filter head structure. Under this design, when the filter rod rotates or moves up and down within the connecting ring, it can always maintain movement along the central axis of the filter head pre-embedded seat, avoiding problems such as filter rod jamming and uneven wear caused by axial deviation.

[0020] A further improved solution: air holes are provided on the filter rod, the air holes are evenly distributed along the circumference of the filter rod, and the air holes communicate with the inner cavity of the filter rod.

[0021] Based on the above technical solution: The pores are evenly distributed along the circumference of the filter rod, which helps to disperse the stress borne by the filter rod during operation. During the operation of the filter bed, the filter rod is subjected to various forces such as water flow, the gravity of the filter media, and backwashing. These forces may cause stress concentration in the filter rod, thus affecting its structural strength and service life. The evenly distributed pores can disperse stress throughout the entire circumference of the filter rod, reducing damage caused by excessive local stress and enhancing the filter rod's resistance to deformation and fracture. Simultaneously, the design of the pores communicating with the inner cavity of the filter rod allows the air pressure inside and outside the filter rod to maintain a relative balance. During the operation of the filter bed, changes in air pressure inside and outside the filter rod may generate additional pressure. The presence of pores can promptly regulate the internal and external air pressure, preventing deformation or damage to the filter rod due to excessive pressure difference, further improving the durability of the filter rod.

[0022] A further improved solution: an air slit is provided at the end of the filter rod away from the air hole, the air slit is connected to the inner cavity of the filter rod, and the air slit is evenly distributed along the circumference of the filter rod.

[0023] Based on the above technical solution: During operation, the filter rod is subjected to various forces, such as water flow impact and the weight of the filter media. The air gaps are evenly distributed along the circumference of the filter rod, distributing these forces throughout the entire circumference and reducing localized stress concentration. This stress dispersion reduces the risk of deformation or breakage due to excessive stress, thus improving the structural stability of the filter rod.

[0024] A further improved solution: The filter cap is fixed to the filter head pre-embedded seat by bolts. The filter head pre-embedded seat is provided with a lower flange for installing the bolts, and the filter cap is provided with an upper flange for installing the bolts. Both the upper flange and the lower flange are provided with through holes for the bolts to pass through. The upper flange and the filter cap are an integral structure, and the lower flange and the filter head pre-embedded seat are an integral structure.

[0025] Based on the above technical solution: the filter cap is fixed to the filter head pre-embedded seat with bolts. This connection method can provide strong connection force. The pre-tightening force of the bolts can tightly press the filter cap and the filter head pre-embedded seat together, making them a whole, effectively resisting various external forces generated during the operation of the filter bed, such as water flow impact force and filter media pressure.

[0026] The beneficial effects of this utility model are as follows:

[0027] This invention features a filter rod with an external thread and a filter head pre-embedded seat with an internal thread that mates with the external thread of the filter rod. The filter rod is threaded onto the filter head pre-embedded seat. This threaded connection allows the filter rod to rotate relative to the filter head pre-embedded seat. During rotation, the filter rod moves up and down along the axial direction, thereby adjusting the height of the filter head.

[0028] An anti-loosening component is installed between the filter head pre-embedded seat and the filter rod to prevent the filter rod from rotating accidentally relative to the filter head pre-embedded seat. During the operation of the filter tank, water flow and air flow will exert a certain impact force on the filter head. Without the anti-loosening component, the filter rod may rotate under the action of these forces, causing changes in the height of the filter head and affecting the backwashing effect of the filter tank. The anti-loosening component ensures that the filter rod remains stable during normal use and will not rotate arbitrarily due to external factors, ensuring that the filter head height is always in the set position.

[0029] Adjustable filter heads solve the problem of non-adjustable filter head height in existing technologies, eliminating the need for fabricating and installing prefabricated templates with high horizontal precision requirements, thus greatly saving labor time and reducing costs. At the same time, by adjusting the position of the filter rod relative to the filter head's embedded seat, it can more flexibly adapt to different backwashing scenarios and requirements of the filter bed, improving the stability and reliability of the filter bed's operation.

[0038] The filter rod 1 is threaded onto the filter head pre-embedded seat 2. The filter rod 1 has an external thread, and the filter head pre-embedded seat 2 has an internal thread that mates with the external thread on the filter rod 1. The filter head pre-embedded seat 2 is cylindrical and is coaxially arranged with the filter rod 1.

[0039] An anti-loosening component is provided between the filter head pre-embedded seat 2 and the filter rod 1 to prevent the filter rod 1 from rotating accidentally relative to the filter head pre-embedded seat 2.

[0040] The anti-loosening component includes an anti-loosening cylinder 4, the lower end of which abuts against the upper end of the filter rod 1. The anti-loosening cylinder 4 is threaded onto the filter head pre-embedded seat 2. The anti-loosening cylinder 4 has an external thread, and the filter head pre-embedded seat 2 has an internal thread that mates with the external thread on the anti-loosening cylinder 4. An anti-loosening spring 5 is also provided between the anti-loosening cylinder 4 and the filter head pre-embedded seat 2 to prevent the anti-loosening cylinder 4 from rotating accidentally relative to the filter head pre-embedded seat 2. The anti-loosening cylinder 4 includes a cylinder body 7 and a positioning ring 6 disposed on the cylinder body 7. The cylinder body 7 and the positioning ring 6 are an integral structure. The diameter of the cylinder body 7 is smaller than the diameter of the positioning ring 6. The cylinder body 7 and the positioning ring 6 are coaxially arranged, and the external thread on the anti-loosening cylinder 4 is disposed on the positioning ring 6. The filter head pre-embedded seat 2 is also provided with a connecting ring 8 that mates with the filter rod 1. The connecting ring 8 and the filter head pre-embedded seat 2 are an integral structure. The internal thread on the filter head pre-embedded seat 2, which mates with the external thread on the filter rod 1, is provided on the connecting ring 8. The connecting ring 8 and the filter head pre-embedded seat 2 are coaxially arranged. The upper end of the anti-loosening spring 5 contacts the lower end of the positioning ring 6, and the lower end of the anti-loosening spring 5 contacts the upper end of the connecting ring 8. When installing the adjustable filter head, the operator can first fix the filter head pre-embedded seat 2, then coaxially install the connecting ring 8 into the filter head pre-embedded seat 2, then install the filter rod 1, and then screw the anti-loosening sleeve 4 into the filter head pre-embedded seat 2 so that the positioning ring 6 contacts the anti-loosening spring 5. Because the axial positioning between each component is clear, it is easier to ensure the correct position and fitting accuracy of each component during installation, reducing the time and difficulty of installation and debugging.

[0041] Specifically: Air holes 9 are provided on the filter rod 1, and the air holes 9 are evenly distributed along the circumference of the filter rod 1, communicating with the inner cavity of the filter rod 1. An air slit 10 is also provided at the end of the filter rod 1 away from the air holes 9, and the air slit 10 communicates with the inner cavity of the filter rod 1, also being evenly distributed along the circumference of the filter rod 1. The filter cap 3 is fixed to the filter head pre-embedded seat 2 by bolts. The filter head pre-embedded seat 2 is provided with a lower flange 11 for mounting the bolts, and the filter cap 3 is provided with an upper flange 12 for mounting the bolts. Both the upper flange 12 and the lower flange 11 are provided with through holes for the bolts to pass through. The upper flange 12 and the filter cap 3 are an integral structure, and the lower flange 11 and the filter head pre-embedded seat 2 are an integral structure. When installing the filter cap 3, the operator only needs to place the filter cap 3 on the filter head pre-embedded seat 2, align the through holes of the upper and lower flanges 11, then insert the bolts and tighten the nuts to complete the installation. This installation method is simple and quick, requiring no complicated tools or operating procedures, greatly shortening the installation time and improving installation efficiency.

[0042] The working principle of this embodiment:

[0043] During initial installation, the filter head can be adjusted to a suitable height according to the design requirements and actual operating conditions of the filter tank. After the filter tank has been running for a period of time, if the backwashing effect is not ideal, it may be due to an unsuitable filter head height. In this case, the filter rod 1 can be rotated again to adjust the filter head height to achieve the best backwashing effect. During adjustment, care should be taken to apply moderate force to avoid damaging the threads due to excessive force. Simultaneously, because an anti-loosening component is installed between the filter head pre-embedded seat 2 and the filter rod 1, after adjusting to the appropriate height, the anti-loosening component will prevent the filter rod 1 from rotating accidentally, ensuring the stability of the filter head height.

[0044] This utility model is not limited to the above-mentioned optional embodiments. Under the premise of non-contradiction, the various solutions can be combined arbitrarily. Anyone can derive other forms of products under the guidance of this utility model.
