Description

Technical Field

[0001] This utility model relates to the field of water treatment equipment technology, and in particular to a water softening treatment device. Background Technology

[0002] With the improvement of people's living standards and the increasingly stringent requirements for water quality in industrial production, water softening equipment is widely used in domestic water supply, boiler feedwater, and industrial cooling circulating water applications. The core working principle of water softening equipment is to use ion exchange resin to adsorb calcium and magnesium ions in the raw water, reducing water hardness. When the resin becomes saturated, a high-concentration brine (sodium chloride solution) must be introduced to backwash and regenerate the resin to restore its exchange capacity. Therefore, the brine tank, as a key component in the preparation of the regenerated solution, directly determines the softening effect of the entire system.

[0003] However, in practical applications of existing technologies, brine tanks typically employ static storage, meaning a large amount of salt is directly piled up inside the tank. Due to salt's strong hygroscopic properties, during prolonged static storage, the accumulated salt particles are prone to caking due to changes in ambient humidity or the dissolution of the underlying brine solution. This caking often forms a hard, arched structure within the salt layer, commonly known as a "salt bridge." Once a salt bridge forms, even if supplemental water is added to the bottom of the brine tank, the salt blocks above are unlikely to fall naturally and come into contact with the water, making it difficult for the bottom water to form a saturated brine solution, and sometimes even resulting in an "empty shelf" phenomenon where there is only water and no salt.

[0004] The existence of this "salt bridge" phenomenon directly leads to a severe deficiency in the concentration of regenerated liquid drawn into the control valve during the salt absorption process. This makes it difficult to effectively replace calcium and magnesium ions in the resin, resulting in resin regeneration failure and the production of substandard hard water by the softening water equipment. Currently, most equipment on the market lacks an effective automatic bridge-breaking mechanism, often requiring manual periodic inspection and manual breaking of salt blocks with tools. This not only increases the maintenance burden on users but also makes it difficult to guarantee the stability of the equipment during long-term unattended operation. Therefore, a softening water treatment device is proposed to solve the above problems. Utility Model Content

[0005] In view of the problems in the existing water softening treatment device, such as the salt particles inside the brine tank easily forming salt bridges due to moisture and hardening, resulting in insufficient salt concentration during resin regeneration and affecting the water treatment effect, and the filter screen at the inlet end being fixed and difficult to disassemble and clean quickly, causing easy blockage of the pipeline, this utility model aims to provide a water softening treatment device with an improved structure that can effectively solve the above problems.

[0006] This utility model provides a water softening treatment device, including a resin tank and a brine tank. The control valve is installed on the top of the resin tank. The control valve is connected to a sewage pipe, a brine pipe, a raw water pipe, and a softened water pipe. The central pipe passes through the inside of the resin tank. The water softening treatment device also includes a vibration mechanism installed inside the brine tank and a quick disassembly mechanism installed at the bottom of the control valve.

[0007] The vibration mechanism includes the connecting plate, the first connecting rod, the rotating shaft, the second connecting rod, the buffer spring, the slide rail, the eccentric wheel, the motor, and the salt tank. The motor drives the eccentric wheel to rotate, the eccentric wheel drives the rotating shaft to perform eccentric motion, the rotating shaft drives the slide rail to perform reciprocating motion, the upper and lower ends of the slide rail are respectively connected to the first connecting rod and the second connecting rod and drive them to move up and down, the connecting plate is installed on the top of the first connecting rod, the connecting plate vibrates the bottom of the salt tank, and the lower part of the second connecting rod is connected to the buffer spring.

[0008] The quick-release mechanism includes a first connecting block, a second connecting block, a knob, a rotating wheel, a locking groove, a flexible caliper, a locking block, a mounting hole, and a filter screen. The second connecting block is fixed to the bottom of the control valve, the first connecting block is inserted into the second connecting block, and the filter screen is disposed inside the first connecting block. The first connecting block is connected to the raw water pipe via the second connecting block. The vibration mechanism physically disrupts the salt bridge, and the quick-release mechanism solves the problem of convenient filter screen cleaning.

[0009] Preferably, the rotating wheel is rotatably installed inside the connecting block two. The elastic caliper is fixedly installed on the rotating wheel along the radial direction of the circumference. The elastic caliper that cooperates with the rotating wheel is fixedly installed inside the mounting hole of the connecting block two. The elastic calipers can provide a clear damping feel and positioning feedback for the rotation operation of the rotating wheel through elastic compression and locking, and prevent the locking mechanism from being accidentally loosened due to vibration during equipment operation.

[0010] Preferably, the bottom of the rotating wheel is connected to the locking block, and the second connecting block is provided with the locking groove. The locking block can rotate with the rotating wheel and rotate inside the locking groove to the locked or unlocked state. This groove and locking block cooperation structure can withstand large axial water pressure, ensuring the sealing and connection reliability of the first connecting block in the locked state.

[0011] Preferably, the knob is connected to the rotating wheel to drive the rotating wheel to rotate. The outer surface of the knob may be provided with anti-slip texture, so that the operator can operate reliably even when the hands are wet or oily, thus improving the convenience of maintenance.

[0012] Preferably, the brine tank has a guide groove on its inner wall, and the salt box is slidably disposed in the guide groove. The guide groove provides precise guidance and limiting for the salt box, ensuring that when the salt box is vibrated by the connecting plate, it only reciprocates in the vertical direction, avoiding unnecessary horizontal shaking and friction, and ensuring the stability of the vibration effect.

[0013] Preferably, the water distributor is connected to the upper and lower ends of the central pipe, the central pipe passes through the quick-release mechanism and is connected to the control valve, and the lower water distributor is connected to the soft water pipe. This pipeline arrangement ensures that the raw water, after being treated by the filter screen and resin tank, can be evenly collected by the lower water distributor and discharged through the central pipe to form a complete circulating water circuit.

[0014] Preferably, the filter screen is located inside the connecting block 1, and is used to effectively filter the silt and suspended solids in the raw water before it enters the resin tank, so as to protect the subsequent resin from being contaminated or blocked by particulate matter, and ensure the service life and exchange efficiency of the resin.

[0015] This utility model has the following beneficial effects:

[0016] 1. This utility model, by setting a vibration mechanism inside the brine tank, uses a motor to drive an eccentric wheel in conjunction with a slide rail and connecting rod assembly to convert rotational motion into vibration force that drives the brine tank to move vertically back and forth. This solves the problem in the prior art where the brine tank of a water softening device is prone to salt bridges due to moisture and caking of salt particles, resulting in difficulty for salt to fall and dissolve and insufficient concentration of regenerated liquid. It achieves the technical effect of effectively destroying the salt bridge structure, ensuring smooth falling and dissolving of salt particles, ensuring resin regeneration effect and equipment operation stability.

[0017] 2. This utility model solves the problems of cumbersome disassembly of the inlet filter assembly in the prior art, which often requires professional tools and is difficult to clean and maintain regularly, by setting a quick disassembly mechanism at the water inlet end of the control valve and using the plug-in cooperation of connecting block one and connecting block two and the fixing of the rotation locking component. It achieves the technical effect of quickly pulling out the filter screen for cleaning without tools, effectively preventing the pipeline and resin tank from being blocked by the accumulation of mud and sand, extending the service life of the equipment, and greatly improving the convenience of user maintenance.

[0018] 3. This utility model solves the problem that existing locking structures are prone to loosening due to equipment vibration or lack of clear feedback when locked in place by setting mutually cooperating elastic calipers on the inner wall of the rotating locking component's wheel and mounting hole. It utilizes the damping and locking effect generated by elastic deformation to achieve the technical effects of providing clear "click" audible feedback and tactile confirmation during rotation locking, using elastic damping to achieve anti-loosening self-locking, ensuring reliable sealing of the water inlet connection and operational safety.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Detailed Implementation

[0026] See Figures 1 to 4 This utility model provides a water softening treatment device, which aims to solve the technical problems in existing water softening equipment, such as the salt tank being prone to moisture and caking, forming salt bridges and resulting in poor regeneration effect, and the inlet filter screen being fixed and locked, making it difficult to quickly disassemble and clean, leading to easy pipe blockage.

[0027] The main structure of the water softening treatment device includes a resin tank 1 and a brine tank 2 located on one side of the resin tank 1. The resin tank 1 serves as the core reaction vessel for containing ion exchange resin, while the brine tank 2 stores the regeneration brine and salt blocks. A control valve 4 is fixedly installed on the top of the resin tank 1. The control valve 4 serves as the fluid control center for switching between operation, backwashing, brine suction, and forward washing processes. The outer periphery of the control valve 4 is connected to a sewage pipe 3, a brine pipe 7, a raw water pipe 8, and a soft water pipe 9, respectively. The sewage pipe 3 extends to the sewer outlet to discharge the sewage generated during backwashing. The brine pipe 7 extends into the brine tank 2 to draw in the regeneration brine. The raw water pipe 8 is used to introduce external hard water to be treated, and the soft water pipe 9 is used to transport the treated soft water to the point of use.

[0028] The water softening device also integrates a vibration mechanism 5 installed inside the brine tank 2 and a quick-release mechanism 6 installed at the bottom of the inlet of the control valve 4. The vibration mechanism 5 is used to generate a vertical reciprocating motion to break the internal structure of the brine tank 59. The quick-release mechanism 6 is connected in series on the inlet path of the raw water pipe 8 and the resin tank 1. The central pipe 10 is vertically inserted into the internal cavity of the resin tank 1. The upper end of the central pipe 10 passes through the quick-release mechanism 6 and is sealed and connected to the internal flow channel of the control valve 4. The lower end of the central pipe 10 is connected to a lower water distributor. The resin tank 1 is filled with a large amount of resin. After the raw water is initially filtered by the quick-release mechanism 6, it enters the resin tank 1 and undergoes an ion exchange reaction with the resin. The converted soft water is collected by the lower water distributor and flows upward along the central pipe 10 to the soft water pipe 9 for discharge.

[0029] The vibration mechanism 5 mainly consists of a motor 58, an eccentric wheel 57, a slide rail 56, and a connecting rod assembly. The motor 58, as the power source, is fixedly installed on the internal support or side wall of the brine tank 2. The output shaft of the motor 58 is fixedly connected to the center of the eccentric wheel 57 and drives the eccentric wheel 57 to rotate. A rotating shaft 53 is fixedly installed at a non-center position on the disc surface of the eccentric wheel 57. The rotating shaft 53 performs eccentric circular motion as the eccentric wheel 57 rotates. The slide rail 56 is horizontally opened in the middle of the connecting rod assembly. The rotating shaft 53 is slidably fitted in the internal groove of the slide rail 56. When the rotating shaft 53 rotates with the eccentric wheel 57, the rotating shaft 53 slides back and forth in the horizontal direction in the slide rail 56. At the same time, the vertical component force drives the slide rail 56 and the connecting rod assembly to perform reciprocating lifting and lowering motion in the vertical direction, thereby converting the rotational motion of the motor 58 into the linear reciprocating vibration of the connecting rod assembly.

[0030] The linkage assembly includes a first linkage 52 located above the slide rail 56 and a second linkage 54 located below the slide rail 56. The bottom end of the first linkage 52 is fixedly connected to the top end of the slide rail 56. A connecting plate 51 is fixedly installed on the top end of the first linkage 52. The connecting plate 51 has a flat plate structure and its top surface directly abuts against the bottom plane of the salt tank 59. It is used to apply the impact force transmitted by the first linkage 52 to the salt tank 59 to generate a vibration effect. The top end of the second linkage 54 is fixedly connected to the bottom end of the slide rail 56. A buffer spring 55 is connected to the bottom end of the second linkage 54. The bottom end of the buffer spring 55 is fixed to the bottom wall of the brine tank 2. The buffer spring 55 plays a role in bottom support and energy buffering during vibration, preventing excessive vibration amplitude from damaging the salt tank 59 and reducing mechanical damage caused by hard impact.

[0031] The salt tank 59 is slidably fitted inside the brine tank 2. The inner wall of the brine tank 2 is provided with a guide groove or limiting structure that matches the outer wall of the salt tank 59. This is used to limit the horizontal displacement of the salt tank 59 and guide the salt tank 59 to move up and down with a limited stroke only in the vertical direction. Driven by the motor 58, the connecting plate 51 continuously rises and falls to impact the bottom of the salt tank 59. Combined with the elastic action of the buffer spring 55, the salt tank 59 generates high-frequency vibration, thereby effectively destroying the internal salt bridge and preventing salt residue from depositing.

[0032] The quick disassembly mechanism 6 is mainly composed of connecting block 1 61 and connecting block 2 62. Connecting block 2 62 serves as a fixed base and is fixedly connected to the water inlet port of control valve 4 by threads or flanges. Connecting block 2 62 has a receiving cavity that matches the shape of connecting block 1 61. Connecting block 1 61 is constructed as a pluggable slider structure and is inserted into the receiving cavity of connecting block 2 62. A filter screen 69 is fixedly installed in the flow channel inside connecting block 1 61. The filter screen 69 is transverse to the water flow direction to intercept the mud and suspended impurities carried in the raw water. The outer end face of connecting block 1 61 is designed with a handle structure for hand gripping. When cleaning is required, connecting block 1 61 and filter screen 69 can be pulled out horizontally from connecting block 2 62.

[0033] The top of the second connecting block 62 has a mounting hole 68, and the bottom of the mounting hole 68 is connected to a locking groove 65 extending to the receiving cavity. A rotating wheel 64 is rotatably installed inside the mounting hole 68. The top of the rotating wheel 64 extends out of the surface of the second connecting block 62 and is fixedly connected to a knob 63. The surface of the knob 63 is provided with anti-slip texture for the operator to rotate. A locking block 67 is fixedly connected to the bottom of the rotating wheel 64. The locking block 67 is located in the locking groove 65. When the first connecting block 61 is fully inserted into the second connecting block 62, rotating the knob 63 drives the rotating wheel 64 and the locking block 67 to rotate. The locking block 67 is screwed into the corresponding slot or limiting step on the first connecting block 61, thereby locking the first connecting block 61 in the axial direction.

[0034] Several elastic calipers 66 are fixedly installed radially on the outer circumferential wall of the rotating wheel 64, and several elastic calipers 66 are also correspondingly installed on the inner wall of the mounting hole 68. The elastic calipers 66 here adopt a pawl or elastic tooth structure with elastic restoring force. When the knob 63 drives the rotating wheel 64 to rotate, the elastic calipers 66 on the rotating wheel 64 and the elastic calipers 66 in the mounting hole 68 come into contact with each other, squeeze and undergo elastic deformation, generating a damping sensation and mechanical positioning effect during rotation. When rotated to the predetermined locking position, the elastic calipers 66 lock together with the rebound force, making a clear clicking sound to indicate that the operation is in place, and using elastic damping to prevent the rotating wheel 64 from rotating back and unlocking due to vibration.

[0035] The implementation principle of this application embodiment is as follows: After the operator completes the equipment installation and connects the raw water pipe 8, the soft water pipe 9 and the sewage pipe 3, the control valve 4 controls the device to enter the softening working state. Under the action of water pressure, the raw water enters the quick disassembly mechanism 6 through the raw water pipe 8. The water flow first passes through the internal filter screen 69 of the connecting block 61. The filter screen 69 intercepts mud and sand and large suspended particles. The raw water after preliminary purification enters the resin tank 1 and fully contacts and reacts with the ion exchange resin. The calcium and magnesium ions that are replaced are adsorbed by the resin. The generated soft water is collected by the bottom water distributor and flows upward along the central pipe 10. Finally, it is discharged from the soft water pipe 9 for the user to use.

[0036] When the resin adsorption reaches saturation and regeneration is required, control valve 4 initiates the regeneration program. Before the brine pipe 7 draws in the brine solution, control valve 4 first controls motor 58 to start. Motor 58 drives eccentric wheel 57 to rotate, which in turn drives eccentrically mounted rotating shaft 53 to perform circular motion. Rotating shaft 53 slides inside slide rail 56 and drives slide rail 56 and connecting rod assembly to perform vertical reciprocating motion. Connecting plate 51 at the top of connecting rod 52 is then lifted and lowered at high frequency and impacts the bottom of salt tank 59. With the elastic buffering effect of buffer spring 55, salt tank 59 vibrates within the stroke groove limited by brine tank 2. Physical vibration effectively destroys the salt bridge structure formed inside salt tank 59 due to moisture, allowing the salt block above to fall and dissolve smoothly. Subsequently, control valve 4 opens the brine suction channel, and brine pipe 7 draws in high-concentration brine solution to backwash and reduce the resin.

[0037] When the water flow decreases after a period of use or routine maintenance is required, the operator manually rotates knob 63. Knob 63 drives wheel 64 to rotate within connecting block 2 62. The elastic caliper 66 on wheel 64 slides through the elastic caliper 66 in mounting hole 68 and undergoes elastic deformation, producing mechanical damping and a clear positioning sound. At the same time, locking block 67 rotates with wheel 64 and disengages from locking groove 65 into unlocked position. The operator holds connecting block 1 61 and pulls it horizontally out of connecting block 2 62 to clean the internal filter screen 69. After cleaning, connecting block 1 61 is pushed back to its original position, and knob 63 is rotated in the opposite direction. Locking block 67 re-engages into locking groove 65 to complete the locking. The elastic calipers 66 interlock under the action of elasticity to achieve anti-loosening self-locking, preventing connecting block 1 61 from accidentally coming off due to equipment vibration.

[0038] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
