Description

Technical Field

[0001] This utility model relates to the technical field of formaldehyde solution storage equipment, specifically a formaldehyde solution purification storage tank equipped with a filtration structure. Background Technology

[0002] Formaldehyde solution has a wide range of applications in chemical, pharmaceutical and other fields, and its storage usually requires special storage tanks. However, most existing formaldehyde solution storage tanks only have storage functions. During the formaldehyde solution storage process, impurities may be mixed into the solution. If these impurities are not treated in time, they will affect the purity and effectiveness of the formaldehyde solution. An existing patent, CN222698749U, describes a formaldehyde solution dispensing tank with precise volume control. First, the dispensing tank body is placed on a fixed base, which limits the position of the dispensing tank body to enhance its stability. The lower end of the support frame is equipped with rollers, which facilitates quick and easy movement of the device to a designated position, improving the ease of use of the formaldehyde solution dispensing tank. After the formaldehyde solution fills the control tank, the valve is closed. By pulling the pull ring upward, the connecting piece simultaneously moves the moving block and connecting rod upward. The sealing plugs one and two move upward simultaneously, opening the vent and dispensing port, thereby achieving precise volume control dispensing and avoiding errors in the dispensing of formaldehyde solution. This helps to optimize the precise dispensing performance of the formaldehyde solution dispensing tank.

[0003] Regarding the aforementioned technologies, the inventors believe that the following defects exist: Although some storage tanks are equipped with simple filtration devices at the inlet or outlet, the filtration effect is poor, and the filtration structure is inconvenient to clean and replace. After long-term use, the filtration capacity will decrease significantly, failing to meet the demand for high-quality storage of formaldehyde solution. Therefore, we propose a formaldehyde solution purification storage tank equipped with a filtration structure to solve the above-mentioned problems. Utility Model Content

[0023] 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.

[0024] Please see Figures 1-6 This utility model provides a technical solution: a formaldehyde solution purification storage tank equipped with a filter structure, including a tank body 1, a fixed pipe 3 fixedly connected to the right side of the outer peripheral surface of the tank body 1, the fixed pipe 3 communicating with the tank body 1, and a fixed connector 301 fixedly connected to the side of the fixed pipe 3 away from the tank body 1, the fixed connector 301 communicating with the fixed pipe 3, and a plug ring assembly 3011 fixedly connected to the side of the fixed connector 301 away from the fixed pipe 3.

[0025] The insert ring assembly 3011 has a ring structure, and a guide rail assembly 3012 is fixedly connected to the right side of the outer periphery of the tank mechanism 1. The main body of the guide rail assembly 3012 is arranged horizontally, and a horizontal groove is opened inside the guide rail assembly 3012. A filter assembly 3013 is installed on the right side of the fixed joint 301 and the insert ring assembly 3011. An annular groove is opened on the outer side of the filter assembly 3013. The annular groove is a positioning slot 3014. There are two positioning slots 3014.

[0026] By setting up the tank body mechanism 1, fixed pipe 3, fixed joint 301, plug ring assembly 3011, guide rail assembly 3012 and filter assembly 3013 with positioning slot 3014, the initial connection and positioning of the filter structure and the storage tank are realized, laying the foundation for subsequent filtration operations.

[0027] See Figures 1-2 Two positioning slots 3014 are respectively opened on the left and right sides of the filter assembly 3013, and a filter screen assembly 3015 is embedded in the inner side of the filter assembly 3013. The filter assembly 3013 and the filter screen assembly 3015 together form a filter structure.

[0028] The positioning slots 3014 on both sides of the filter assembly 3013 and the filter screen assembly 3015 on the inner side form a complete filter structure, which improves the filtration effect and clarifies the composition and positional relationship of the filter components.

[0029] See Figures 5-6An adjusting push rod 3016 is fixedly connected inside the transverse groove opened in the guide rail assembly 3012. The adjusting push rod 3016 is arranged horizontally, and a movable bracket 3017 is fixedly connected to the left side of the adjusting push rod 3016. The movable bracket 3017 is slidably connected inside the guide rail assembly 3012.

[0030] By setting an adjusting push rod 3016 and a movable bracket 3017 in the transverse groove of the guide rail assembly 3012, and with the movable bracket 3017 slidably connected in the guide rail assembly 3012, the transverse position adjustment function of the movable bracket 3017 is realized.

[0031] See Figures 1-2 The movable support 3017 is fixedly connected to the inner side of the movable support 3017, and the movable support 3018 is fixedly connected to the right side of the movable support 3018. The liquid inlet flange 3019 and the movable support 3018 together form the liquid inlet structure.

[0032] The formaldehyde solution is stably introduced by the liquid inlet structure formed by the movable pipe 3018 inside the movable bracket 3017 and the liquid inlet flange 3019 on its right side.

[0033] See Figures 3-5 A movable joint 3020 is fixedly connected to the side of the movable pipe 3018 away from the liquid inlet flange 3019. A ring assembly 3011 is also fixedly connected to the outside of the movable joint 3020. A support leg assembly 101 is fixedly connected to the bottom end face of the tank body mechanism 1.

[0034] By providing a movable joint 3020 and an outer ring assembly 3011 on the side of the movable pipe 3018 away from the liquid inlet flange 3019, and by providing a support leg assembly 101 at the bottom of the tank body mechanism 1, the connection flexibility between the liquid inlet part and the filter structure is enhanced, while providing support for the tank body mechanism 1.

[0035] See Figures 1-2 There are three support leg assemblies 101, and the three support leg assemblies 101 are fixedly connected to the bottom end face of the tank body mechanism 1 in a ring array. The outer side of each of the three support leg assemblies 101 is fixedly connected to a foot assembly 1011, and the foot assembly 1011 has a mounting hole 1012 inside.

[0036] The three outrigger assemblies 101 arranged in a ring and the foot assemblies 1011 with mounting holes 1012 on their outer sides provide stable support for the tank mechanism 1 and facilitate convenient installation and fixing.

[0037] See Figures 2-5A bearing seat 2 is installed at the top of the tank body mechanism 1, a servo motor 201 is installed at the top of the bearing seat 2, a connecting component 2011 is installed on the bottom output shaft of the servo motor 201, a blade assembly 2012 is fixedly connected to the outer side of the connecting component 2011 in a ring array, and a drain pipe 2013 is fixedly connected to the bottom of the tank body mechanism 1, and a drain flange 2014 is fixedly connected to the bottom of the drain pipe 2013.

[0038] By setting a bearing seat 2, a servo motor 201, a connecting component 2011 and a blade assembly 2012 at the top of the tank body mechanism 1, and setting a drain pipe 2013 and a drain flange 2014 at the bottom, the stirring function of the solution inside the tank and the convenient discharge function of the solution are realized.

[0039] During operation, firstly, the tank body mechanism 1 is fixedly installed in the designated position through the support leg assembly 101 and the outer support foot assembly 1011, using the mounting holes 1012 inside the support foot assembly 1011 to ensure the overall stability of the storage tank. The formaldehyde solution enters the movable pipe 3018 through the liquid inlet flange 3019. The liquid inlet structure composed of the movable pipe 3018 and the liquid inlet flange 3019 guides the solution to flow to the movable joint 3020.

[0040] The adjustment push rod 3016 inside the guide rail assembly 3012 is activated, pushing the movable bracket 3017 to move laterally in the transverse groove of the guide rail assembly 3012. The movable bracket 3017 drives the movable tube 3018 and the movable connector 3020 to move synchronously, so that the insertion ring assembly 3011 on the outside of the movable connector 3020 is inserted into the positioning slot 3014 on the right side of the filter assembly 3013.

[0041] At this time, the insertion ring assembly 3011 on the outside of the fixed connector 301 has been inserted into the positioning slot 3014 on the left side of the filter assembly 3013, realizing the positioning and installation of the filter assembly 3013. The filter assembly 3013 and the filter screen assembly 3015 embedded inside form a filter structure.

[0042] Formaldehyde solution flows into filter assembly 3013 from movable connector 3020. After being filtered by filter screen assembly 3015, impurities in the solution are removed. The filtered solution enters fixed pipe 3 through fixed connector 301 and then flows into tank mechanism 1 for storage.

[0043] When it is necessary to stir the formaldehyde solution in the tank, the servo motor 201 at the top of the bearing seat 2 is started. The output shaft of the servo motor 201 drives the blade assembly 2012 to rotate through the connecting assembly 2011, thereby stirring the solution in the tank mechanism 1.

[0044] When it is necessary to discharge the formaldehyde solution, the solution is discharged from the storage tank through the drain pipe 2013 at the bottom of the tank body mechanism 1 and the drain flange 2014.

[0045] When the filter structure needs to be cleaned or replaced, adjust the push rod 3016 to move the movable bracket 3017 and the movable joint 3020 to the right, so that the insertion ring assembly 3011 on the outside of the movable joint 3020 disengages from the positioning slot 3014 on the right side of the filter assembly 3013, and the filter assembly 3013 can be removed. The filter screen assembly 3015 can then be cleaned or replaced. After replacement, the filter assembly 3013 can be reinstalled according to the above steps.

[0046] In summary, this device, equipped with the paddle assembly 2012, can achieve rapid mixing operations.

[0047] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.
