Description

Technical Field

[0001] This utility model belongs to the field of formaldehyde solution technology, specifically relating to a formaldehyde production and storage device. Background Technology

[0002] Formaldehyde is an organic compound that has a wide range of applications in daily life and industry, but it also poses certain risks to human health. Formaldehyde usually appears in the form of an aqueous solution and is easily soluble in water and ethanol. A 35-40% aqueous solution of formaldehyde is called formalin.

[0003] As disclosed in the publication (announcement) number CN220885337U, this utility model provides a storage device for formaldehyde solution production, relating to the field of formaldehyde solution production technology. It includes a base, pulleys, a protective railing, and a storage tank. The top of the storage tank is connected to an inlet / outlet pipe, and a light-shielding mechanism is provided between the protective railing and the storage tank. This utility model fixes the light-shielding plate to the inside of the protective railing by inserting a light-shielding plate into the gap between the storage tank and the protective railing, and clamping the bottom end of the locking plate to the threaded rod using a threaded rod, a locking plate, and a nut. Then, a top plate is fixed to the top of the storage tank using a locking block and a locking groove. This allows the light-shielding plate and the top plate to cooperate in enclosing the storage tank, preventing direct sunlight from causing changes in its internal temperature. This solves the problem in existing technologies where the lack of a light-shielding mechanism leads to the formaldehyde solution being exposed to light for a long time, causing the temperature to rise and deteriorate into formic acid, affecting its normal use.

[0004] Analysis revealed that the solution completely isolates the liquid storage tank with a light-shielding plate, resulting in poor internal ventilation. The storage area must maintain good ventilation to prevent the accumulation of formaldehyde gas, which poses certain hazards to human health and the storage environment. To address these issues, the solution needs to be optimized and improved. Utility Model Content

[0005] To address the problems existing in the background technology, this utility model provides a formaldehyde production and storage device; it has a better ventilation environment and can effectively improve the fire safety of the storage site.

[0006] This utility model provides a formaldehyde production and storage device, including a protective shell, a plurality of storage tanks evenly arranged inside the protective shell, a sealing mechanism corresponding to each storage tank in the protective shell, and a high-efficiency ventilation component corresponding to each storage tank in the protective shell; the high-efficiency ventilation component includes a fan located on one side of the protective shell, the air outlet of the fan being interconnected with the interior of the protective shell, a branch pipe connected to the side of the protective shell away from the fan, a main exhaust pipe connecting the branch pipes, and a groove provided on the inner bottom surface of the protective shell, with the branch pipes communicating with the groove.

[0007] Furthermore, the sealing mechanism includes a connecting pipe corresponding to the storage tank, a sealing cap is hinged to the connecting pipe, and a rubber plug is fixedly installed on the sealing cap corresponding to the connecting pipe.

[0008] Furthermore, a corrugated pipe is fixedly installed at the outlet end of the main exhaust pipe.

[0009] Furthermore, a thermometer is fixedly installed on one side of the protective shell.

[0010] Furthermore, an observation window is provided on one side of the protective shell, and a sliding groove is fixedly installed on the protective shell corresponding to the observation window. A light shield is slidably connected in the sliding groove, and a control plate is fixedly installed on the light shield.

[0011] Furthermore, the storage bucket is made of borosilicate glass.

[0012] The beneficial effects of this utility model are:

[0013] This invention features a highly efficient ventilation component designed through structural improvements and optimizations. This component can periodically release formaldehyde released from inside the protective shell. Since formaldehyde is slightly denser than air, even a small amount of formaldehyde leakage will accumulate at lower levels. The designed grooves effectively remove formaldehyde from these lower levels, keeping the inside of the protective shell clean, ensuring the safety of workers, and reducing the risk of fire.

[0019] 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.

[0020] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed," "equipped with," and "connected," etc., should be interpreted broadly. For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0021] Please refer to the accompanying diagrams in all instruction manuals:

[0022] A formaldehyde production and storage device includes a protective shell 1, a plurality of storage tanks 2 evenly arranged inside the protective shell 1, a sealing mechanism corresponding to each storage tank 2 in the protective shell 1, and a high-efficiency ventilation component corresponding to each storage tank 2 inside the protective shell 1.

[0023] The high-efficiency ventilation component includes a fan 3 located on one side of the protective shell 1. The air outlet of the fan 3 is connected to the interior of the protective shell 1. A branch pipe 4 is connected to the side of the protective shell 1 away from the fan 3. A main exhaust pipe 5 is connected between the branch pipes 4. A groove 6 is provided on the inner bottom surface of the protective shell 1. The branch pipes 4 and the groove 6 are connected to each other.

[0024] As can be seen from the above description, when the power supply of the ventilation fan 3 is connected, the operation of the fan 3 brings clean outside air into the protective shell 1, and the airflow carries out the leaked formaldehyde gas, which enters the branch pipe 4 through the groove 6 and is finally discharged through the main exhaust pipe 5. The main exhaust pipe 5 is connected to the corresponding exhaust pipe to facilitate the centralized treatment of polluted gas.

[0025] Formaldehyde has a flash point of 50℃ (37% aqueous solution). At room temperature, it is easily ignited when exposed to a source of ignition or heat. The flame spreads quickly and can cause a fire. Formaldehyde can effectively reduce the risk of fire.

[0026] As a technical optimization of this utility model, the sealing mechanism includes a connecting pipe 7 corresponding to the storage tank 2, a sealing cover 8 hinged to the connecting pipe 7, and a rubber plug 9 fixedly installed on the sealing cover 8 corresponding to the connecting pipe 7.

[0027] As can be seen from the above description, the rubber stopper 9 on the sealing cap 8 can seal the connecting pipe 7, improve the sealing performance of the storage tank 2, and reduce formaldehyde leakage.

[0028] As a technical optimization of this utility model, a corrugated pipe 10 is fixedly installed at the outlet end of the main exhaust pipe 5.

[0029] As can be seen from the above description, the bellows 10 has the ability to change its shape arbitrarily, which can meet the requirements of gas transportation in various locations and makes it more flexible to use.

[0030] As a technical optimization of this utility model, a thermometer 11 is fixedly installed on one side of the protective shell 1;

[0031] As described above, the recommended storage temperature for formaldehyde solution is generally between 10℃ and 25℃. If the temperature is too low, the formaldehyde solution may undergo a polymerization reaction, leading to turbidity or precipitation; if the temperature is too high, it will accelerate the volatilization of formaldehyde, reduce the solution concentration, and may also increase safety risks such as explosion. Therefore, a thermometer is needed for visual monitoring.

[0032] As a technical optimization of this utility model, an observation window 12 is provided on one side of the protective shell 1, and a sliding groove 13 is fixedly installed on the protective shell 1 corresponding to the observation window 12. A light shield 14 is slidably connected in the sliding groove 13, and a control plate 15 is fixedly installed on the light shield 14.

[0033] As can be seen from the above description, the control panel 15 can control the light shield 14 to slide in the slide groove 13, and the observation window 12 can facilitate workers to inspect the storage tank 2 inside the protective shell 1 and eliminate potential hazards in a timely manner.

[0034] As a technical optimization of this utility model, the material of the storage bucket 2 is borosilicate glass;

[0035] As can be seen from the above description, the borosilicate glass storage tank 2 has good chemical stability and can effectively prevent the formaldehyde solution from corroding the container and the container components from contaminating the formaldehyde solution.

[0036] The working process of this utility model is as follows:

[0037] Formaldehyde solution can be stored or extracted from storage tank 2 through connecting pipe 7. The fan 3 is operated periodically, and waste is centrally discharged and recycled through branch pipe 4 and main exhaust pipe 5. Workers can observe the storage tank 2 inside the protective shell 1 in a timely manner by controlling the opening and closing of the observation window 12 through the light shield 14. The overall safety is higher, the fire hazard is reduced, and the health of workers is protected.

[0038] The present invention and its embodiments have been described above. This description is not restrictive, and the specific embodiments shown are only one of the embodiments of the present invention. The actual structure is not limited to this. In short, if a person skilled in the art is inspired by this description and designs a similar structure and embodiment without departing from the inventive spirit of the present invention, such design should fall within the protection scope of the present invention.
