Description

Technical Field

[0001] This utility model relates to the field of urea-formaldehyde resin technology, and in particular to a urea-formaldehyde resin storage device. Background Technology

[0002] Urea-formaldehyde resin, also known as urea-formaldehyde resin, is a binder formed by the condensation of urea and formaldehyde under the action of a catalyst (alkaline or acidic catalyst) to form an initial urea-formaldehyde resin, which then forms an insoluble and infusible final thermosetting resin under the action of a curing agent or additives. Cured urea-formaldehyde resin is lighter in color than phenolic resin, semi-transparent, resistant to weak acids and alkalis, has good insulation properties, excellent wear resistance, and is inexpensive. It is the most widely used type of adhesive, especially in the manufacture of various engineered wood products in the wood processing industry.

[0003] Currently, storage devices are needed to store urea-formaldehyde resin during production or use. Since urea-formaldehyde resin has certain requirements for storage temperature, existing storage devices are equipped with heat preservation mechanisms to maintain temperature stability.

[0004] However, the above-mentioned insulation mechanisms are mostly located on the outside of the storage device, which can easily lead to uneven heat exchange or low heat exchange efficiency. Therefore, we propose a urea-formaldehyde resin storage device. Utility Model Content

[0005] The purpose of this utility model is to provide a urea-formaldehyde resin storage device. By setting up a heat preservation mechanism and utilizing the cooperation of heat preservation components and heat exchange components set inside the storage tank, not only can heat be exchanged more evenly, but the overall heat exchange efficiency is also high, which makes it easier to maintain the storage temperature of urea-formaldehyde resin.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a urea-formaldehyde resin storage device, comprising a storage tank and a tank cover connected to the top of the storage tank, wherein the storage tank is provided with a heat preservation mechanism, the heat preservation mechanism comprising:

[0007] A heat exchange assembly, which is fixedly connected to the inner wall of the storage tank;

[0008] A heat exchange component is provided on the heat exchange component, and the heat exchange component is used to contact urea-formaldehyde resin.

[0009] A connecting component is provided between the storage tank and the heat exchange component, and the connecting component is used to connect the heat exchange component;

[0010] A sealing component is provided at the bottom of the storage container, and the sealing component is used to seal the storage container.

[0011] Preferably, the heat exchange assembly includes;

[0012] Annular pipes, two annular pipes are sequentially arranged in the middle of the storage tank;

[0013] The cross-shaped tube, each of the annular tubes is fixedly connected to the cross-shaped tube inside;

[0014] Fixed sleeves are fixedly connected between the two annular pipes and between the two cross-shaped pipes. An upper ventilation duct is fixedly connected to the middle of the upper annular pipe, and a lower ventilation duct is fixedly connected to the middle of the lower annular pipe.

[0015] Preferably, the thermal insulation component includes:

[0016] A heating wire is fixedly connected inside each of the fixed sleeves;

[0017] The insulation sleeve is fixedly connected to the outside of the fixed sleeve, and the heat exchange fluid is installed inside the insulation sleeve.

[0018] Preferably, the connecting assembly includes a connecting cavity formed at the bottom of the storage tank, a connecting threaded rod fixedly connected to the bottom of the lower annular tube, a connecting ring inserted into the connecting threaded rod, and a connecting nut threadedly connected to one end of the connecting threaded rod.

[0020] Preferably, a feed pipe is fixedly connected to one side of the top of the storage tank, and a discharge pipe is fixedly connected to one side of the bottom of the storage tank.

[0021] The technical effects and advantages of this utility model are as follows:

[0022] The heat exchange components are connected to the storage tank via a connecting assembly. When urea-formaldehyde resin is stored in the storage tank, if the temperature is too high, cold air is introduced from the outside into the heat exchange components. The cold air flows inside the heat exchange components and exchanges heat with the urea-formaldehyde resin through the insulation components, thereby lowering the temperature of the urea-formaldehyde resin. If the temperature is too low, the heat exchange components start to heat, and the insulation components are used to heat the urea-formaldehyde resin, thus maintaining a stable temperature inside the storage tank. The evenly distributed heat exchange components and insulation components work together to achieve relatively uniform heat exchange and have good heat exchange efficiency.

[0028] 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.

[0029] This utility model provides, for example Figure 1-4 The diagram shows a urea-formaldehyde resin storage device.

[0030] Example 1

[0031] The system includes a storage tank 1 and a lid 2 connected to the top of the storage tank 1. The storage tank 1 has an internal insulation mechanism, which includes: a heat exchange component 3 fixedly connected to the inner wall of the storage tank 1; an insulation component 4 mounted on the heat exchange component 3 and used to contact urea-formaldehyde resin; a connecting component 5 between the storage tank 1 and the heat exchange component 3; and a sealing component 6 at the bottom of the storage tank 1 for sealing the storage tank 1. The heat exchange component 3 is connected to the storage tank 1 via the connecting component 5. The bottom of the storage tank 1 is then sealed using the encapsulation component 6. When urea-formaldehyde resin is stored in the storage tank 1, if the temperature is too high, the temperature sensor inside the storage tank 1 will detect the high temperature and transmit it to the controller. At this time, the heat exchange component 3 will receive cold air from the outside. The cold air will flow inside the heat exchange component 3 and exchange heat with the urea-formaldehyde resin through the insulation component 4, thereby reducing the temperature of the urea-formaldehyde resin. If the temperature is too low, the temperature sensor will detect the low temperature and transmit it to the controller, causing the heat exchange component 3 to start heating. The insulation component 4 will then be used to heat the urea-formaldehyde resin, thereby maintaining a stable temperature inside the storage tank 1.

[0032] Furthermore, the heat exchange assembly 3 includes: annular pipes 301, with two annular pipes 301 arranged sequentially in the middle of the storage tank 1; cross-shaped pipes 302, with each annular pipe 301 having a fixed connection to a cross-shaped pipe 302 inside; and fixed sleeves 303, with multiple fixed sleeves 303 fixedly connected between the two annular pipes 301 and between the two cross-shaped pipes 302. An upper ventilation duct 304 is fixedly connected to the middle of the upper annular pipe 301, and a lower ventilation duct 305 is fixedly connected to the middle of the lower annular pipe 301. By setting the heat exchange assembly 3 inside the storage tank 1 and evenly distributing the fixed sleeves 303, and with the annular pipes 301, fixed sleeves 303, and cross-shaped pipes 302 interconnected, heat exchange can be carried out more evenly, thereby improving heat exchange efficiency. The lower ventilation duct 305 can be connected to a cold air inlet port, which facilitates the entry of cold air into the fixed sleeves 303 for heat exchange. This is mainly achieved by opening the valve at the lower ventilation duct 305 and then introducing external cold air.

[0033] Furthermore, the heat insulation component 4 includes: a heating wire 403, which is fixedly connected inside each fixed sleeve 303; and a heat insulation sleeve 401, which is fixedly connected to the outside of the fixed sleeve 303, and a heat exchange fluid 402 is provided inside the heat insulation sleeve 401. Heat exchange is achieved by heating inside the fixed sleeve 303 through the heating wire 403. Through the cooperation of the heat insulation sleeve 401 and the heat exchange fluid 402, heat exchange can be performed on the urea-formaldehyde resin in a relatively uniform manner.

[0034] Furthermore, the connecting assembly 5 includes a connecting cavity 501 opened at the bottom end of the storage tank 1, a connecting threaded rod 502 fixedly connected to the bottom end of the lower annular tube 301, a connecting ring 503 inserted into the connecting threaded rod 502, and a connecting nut 504 threadedly connected to one end of the connecting threaded rod 502; by passing the connecting threaded rod 502 through the storage tank 1, then inserting the connecting ring 503 into the connecting threaded rod 502, and then rotating the connecting nut 504 to screw the connecting nut 504 into the connecting threaded rod 502, so that the connecting nut 504 presses against the connecting ring 503, thereby installing the heat exchange assembly 3 inside the storage tank 1.

[0035] Furthermore, the encapsulation assembly 6 includes an upper flange 602 fixedly connected to the outside of the storage tank 1, an encapsulation cover 601 located below the storage tank 1, a lower flange 603 fixedly connected to the outside of the encapsulation cover 601, encapsulation bolts inserted into the upper flange 602 and the lower flange 603, and encapsulation nuts threadedly connected to the encapsulation bolts; the encapsulation cover 601 is placed at the bottom of the storage tank 1, then the upper flange 602 and the lower flange 603 are aligned, and then the upper flange 602 and the lower flange 603 are connected by the cooperation of the mounting bolts and the mounting nuts, thereby encapsulating the bottom of the storage tank 1 with the encapsulation assembly 6 to prevent large heat loss from the heat exchange assembly 3.

[0036] Furthermore, a feed pipe is fixedly connected to one side of the top of storage tank 1, and a discharge pipe is fixedly connected to one side of the bottom of storage tank 1; urea-formaldehyde resin is fed into storage tank 1 through the feed pipe, and urea-formaldehyde resin is removed from storage tank 1 through the discharge pipe.

[0037] Example 2

[0038] Example 2 further discloses a sealing assembly based on Example 1. The sealing assembly includes a large sealing ring and a small sealing ring that are fixedly connected in sequence at the bottom of the lower annular tube 301. The large sealing ring and the small sealing ring are located on both sides of the connecting threaded rod 502. A rubber ring is also provided between the sealing cover 601 and the storage tank 1.
