Description

Technical Field

[0001] This utility model belongs to the field of formaldehyde production technology, specifically relating to a hot water circulation and oxidation furnace water replenishment tank. Background Technology

[0002] In traditional formaldehyde production processes, the hot water circulation system and the oxidation furnace water replenishment system are constructed as two separate tanks, resulting in a large space occupation and high manufacturing costs. To address this, a composite hot water circulation and oxidation furnace water replenishment system is adopted, which integrates the two tanks into one unit and separates them with a partition in the middle, thereby reducing the space occupation and lowering the manufacturing costs.

[0003] The existing hot water circulation and oxidizer makeup water tank uses a single tank, with a baffle plate inside to divide it into two spaces to provide hot water circulation and oxidizer makeup water. However, it has the following drawbacks:

[0004] (1) When using the composite hot water circulation and oxidation furnace water replenishment tank, the liquid is loaded into the corresponding composite hot water circulation and oxidation furnace water replenishment tank respectively, and discharged through the outlet pipe for water circulation and replenishment. However, when storing water, the existing water tank only controls the water injection manually through the water injection pipe. It requires a dedicated person to continuously monitor the liquid level, which not only increases labor costs, but also has problems such as delayed response and misjudgment in manual operation, resulting in extremely low protection reliability. When manual monitoring is not timely, the liquid is continuously injected into the tank cavity through the water injection pipe, and the liquid level exceeds the safe bearing height of the tank body, causing a sudden increase in internal pressure of the tank body. This may cause the weld of the tank body to crack, the partition to deform, or even the overall tank structure to be damaged. Excessive liquid overflows from the top of the tank body, which on the one hand wastes water resources, and on the other hand makes the ground slippery, increasing the risk of people falling. If the overflowing liquid comes into contact with electrical equipment, it may also cause safety accidents such as short circuits. Therefore, we propose a hot water circulation and oxidation furnace water replenishment tank. Utility Model Content

[0005] The purpose of this utility model is to provide a hot water circulation and oxidation furnace water supply tank to solve the problem mentioned in the background art that the water injection height of the hot water circulation and oxidation furnace water supply tank cannot be controlled in a timely manner.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a hot water circulation and oxidation furnace water replenishment tank, comprising a tank body, wherein a hot water circulation chamber and an oxidation furnace water replenishment chamber are respectively provided inside the tank body, and a water injection pipe and a water outlet pipe are respectively installed on the hot water circulation chamber and the oxidation furnace water replenishment chamber. A mounting bracket is fixed to the end of the water injection pipe by welding, and a blocking plate is slidably connected to the mounting bracket. Two connecting rods are symmetrically fixed to the surface of the blocking plate, and a buoyancy plate is fixed to the connecting rod.

[0007] Preferably, the end face of the mounting bracket and the end face of the water injection pipe are flush with each other, and the surface of the blocking plate and the end face of the mounting bracket are in contact with each other.

[0008] Preferably, the connecting rod has an L-shaped cross-section, and the blocking plate has a rectangular cross-section.

[0009] Preferably, the surface of the blocking plate is provided with a guide hole, and a guide rod passes through the inside of the guide hole. The guide rod is fixed to the end face of the mounting bracket by welding.

[0010] Preferably, the side of the mounting bracket is fixed with a stop block by inlay, and one end of the stop block extends into the interior of the side end of the mounting bracket.

[0011] Preferably, a sealing groove is provided on the end face of the water injection pipe, and a rubber ring is fixed inside the sealing groove by adhesive bonding.

[0012] Preferably, the end of the buoyancy plate is equipped with a convex panel, and the cross-section of the convex panel is an arc-shaped structure.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] (1) Through the designed buoyancy plate, mounting bracket, connecting rod, and blocking plate, when liquid is injected into the tank through the water injection pipe, the liquid rises in the tank, causing it to contact the buoyancy plate and generate buoyancy, making the buoyancy plate rise with the liquid. At the same time, it drives the blocking plate to rise and slide on the mounting bracket, so that the blocking plate blocks the end of the water injection pipe in time, preventing the water from overflowing and damaging the tank due to continuous liquid injection and failure to close in time, as well as causing liquid to overflow. Through the designed guide rod and guide hole, The guide rod is inserted into the guide hole of the blocking plate to support the movement of the blocking plate and prevent it from tilting and affecting the lifting. The designed stop block limits the movement of the blocking plate and prevents it from falling out of the slide groove of the mounting bracket. The designed rubber ring is set at the end of the water injection pipe. When the blocking plate blocks the water injection pipe end, the rubber ring is pressed tightly against the surface of the blocking plate, further improving the sealing and water-stopping effect of the water injection pipe. The designed convex panel is installed on the top of the buoyancy plate to prevent liquid from remaining on the buoyancy plate and affecting its buoyancy effect. Attached Figure Description

[0021] 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.

[0022] Example

[0023] Please see Figures 1 to 5 This utility model provides a technical solution: a hot water circulation and oxidation furnace water supply tank, including a tank body 1. The tank body 1 has a hot water circulation chamber 2 and an oxidation furnace water supply chamber 3 respectively. A water injection pipe 4 and a water outlet pipe 6 are respectively installed on the hot water circulation chamber 2 and the oxidation furnace water supply chamber 3. A mounting bracket 5 is welded to the end of the water injection pipe 4. A blocking plate 10 is slidably connected to the mounting bracket 5. Two connecting rods 9 are symmetrically fixed to the surface of the blocking plate 10. A buoyancy plate 12 is fixed to the connecting rods 9. Through the designed buoyancy plate 12, mounting bracket 5, connecting rods 9, and blocking plate 10, water is injected into the tank body 1 through the water injection pipe 4. When liquid is injected, the liquid rises within the tank 1, causing it to contact the buoyancy plate 12 and generate buoyancy. This causes the buoyancy plate 12 to rise along with the liquid, simultaneously pulling the blocking plate 10 up and sliding on the mounting bracket 5. The blocking plate 10 then blocks the end of the water injection pipe 4, promptly sealing the water injection pipe 4 to prevent the liquid from continuously being injected and failing to close in time, which could lead to overfilling of the tank 1 and damage to the tank body, as well as liquid overflow. The end face of the mounting bracket 5 and the end face of the water injection pipe 4 are flush with each other, and the surface of the blocking plate 10 and the end face of the mounting bracket 5 are in close contact with each other. The connecting rod 9 has an L-shaped cross-section, and the blocking plate 10 has a rectangular cross-section.

[0024] In this embodiment, preferably, the surface of the blocking plate 10 is provided with a guide hole 14, and a guide rod 13 passes through the inside of the guide hole 14. Through the designed guide rod 13 and guide hole 14, the guide rod 13 is inserted into the guide hole 14 of the blocking plate 10 to support the movement of the blocking plate 10 and prevent the blocking plate 10 from tilting and affecting the lifting. The guide rod 13 is fixed to the end face of the mounting bracket 5 by welding.

[0025] In this embodiment, preferably, the side of the mounting bracket 5 is fixed with a stop 8 by embedding, and one end of the stop 8 extends into the inside of the side end of the mounting bracket 5. The stop 8 is designed to limit the movement of the blocking plate 10 and prevent the blocking plate 10 from falling out of the groove of the mounting bracket 5.

[0026] In this embodiment, preferably, a sealing groove is provided on the end face of the water injection pipe 4, and a rubber ring 7 is fixed inside the sealing groove by adhesive bonding. With the design of the rubber ring 7, the rubber ring 7 is set at the port of the water injection pipe 4, so that when the blocking plate 10 blocks at the port of the water injection pipe 4, the rubber ring 7 is close to the surface of the blocking plate 10, which further improves the sealing and water-stopping effect of the water injection pipe 4.

[0027] In this embodiment, preferably, a convex panel 11 is installed at the end of the buoyancy plate 12. The convex panel 11 is designed to be installed on the top of the buoyancy plate 12 so that liquid will not remain on the buoyancy plate 12 and affect the buoyancy effect of the buoyancy plate 12. The cross-section of the convex panel 11 is an arc-shaped structure.

[0028] The working principle and usage process of this utility model are as follows: A partition is installed in the middle of a circular tank 1 to divide the tank 1 into two chambers: a hot water circulation chamber 2 and an oxidation furnace water supply chamber 3. This avoids the need for traditional installation of two tanks, saving space and reducing manufacturing costs. When liquid is injected into the hot water circulation chamber 2 and the oxidation furnace water supply chamber 3 through the water injection pipe 4, the liquid rises in these chambers, contacting the buoyancy plate 12 and generating buoyancy. This causes the buoyancy plate 12 to rise with the liquid, simultaneously causing the blocking plate 10 to slide upwards on the mounting frame 5, blocking the end of the water injection pipe 4. At this time, the position is blocked by the stop block 8, so that the blocking plate 10 stays at the end of the water injection pipe 4, and the water injection pipe 4 is sealed in time to prevent the liquid from being continuously injected and not being closed in time, which would cause the liquid to be overfilled in the tank and damage the tank body 1, and cause the liquid to overflow. This utility model opens the outlet pipe 6 of the corresponding cavity, and the hot water in the hot water circulation tank 2 or the water in the oxidation furnace water replenishment tank 3 is discharged through the outlet pipe 6 to supply the corresponding production process. The liquid level in the tank gradually drops, and the buoyancy of the buoyancy plate 12 decreases synchronously. Under the action of the weight of the buoyancy plate 12, the connecting rod 9 and the blocking plate 10, the blocking plate 10 slides down along the guide rod 13 and disengages from the end of the water injection pipe 4, and the water injection pipe 4 resumes the water inlet channel.

[0029] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
