[0001] This utility model relates to the field of steam equipment technology, and more specifically, to a steam storage and flow control device. Background Technology

[0002] Tunnel steaming equipment is a common type of industrial steaming equipment that uses steam to continuously process food. During operation, the tunnel steaming equipment uses an automated conveying system to send food into a closed steam environment, where it is steamed at a set temperature, humidity, and time, utilizing the heat of the steam to cook the food.

[0003] Tunnel steaming equipment typically includes a tunnel chamber, conveying pipes, and a steam generator. The steam generator heats and evaporates water to produce steam, which is then conveyed through the pipes to the tunnel chamber to heat the food. However, existing tunnel steaming equipment is susceptible to the influence of the steam generator. Problems with the steam generator itself or untimely water replenishment may lead to unstable steam entering the tunnel chamber, thus affecting the steaming quality of the food.

[0004] Therefore, a new solution is needed to address this problem. Utility Model Content

A storage chamber is provided on one side of the tunnel chamber, and a first pressure gauge is provided on the storage chamber. The gas transmission pipeline is connected to the storage chamber, and a plurality of diversion pipes are provided on the storage chamber. A plurality of equally spaced air inlets are provided on the side wall of the tunnel chamber, and the diversion pipes are correspondingly engaged with the air inlets. An inclined first guide plate and a second guide plate are provided inside the storage chamber, and the length of the second guide plate is adjustable.

[0007] The present invention is further configured such that: the second guide plate includes a mother plate and a daughter plate that slides with the mother plate; the mother plate is fixedly connected to the inner wall of the storage cavity; a connecting plate is provided on the daughter plate; a protruding post is fixedly connected to one side of the connecting plate; a sliding groove that slides with the protruding post is provided in the mother plate; and a limiting mechanism is provided between the mother plate and the connecting plate.

[0008] The present invention is further configured such that: the limiting mechanism includes a limiting block that rotates with the connecting plate; the connecting plate has a slot that engages with the limiting block; and a spring is fixedly connected between the slot and the limiting block.

[0009] The present invention is further configured such that a force-applying groove is provided at the upper end of the connecting plate.

[0010] The present invention is further configured such that each of the diversion pipes is provided with a valve and a second pressure gauge, and a pressure relief valve is provided on one side of the storage cavity.

[0011] The present invention is further configured such that: the inner wall of the storage cavity is provided with a gradient insulation layer, the gradient insulation layer includes a vacuum interlayer and a heat insulation layer located outside the vacuum interlayer, and the heat insulation layer is filled with rock wool.

[0012] In summary, this utility model has the following beneficial effects:

[0013] By setting a storage chamber on one side of the tunnel chamber, the steam generated by the steam generator is first stored in the storage chamber and then distributed to various parts of the tunnel chamber. By storing the steam in the storage chamber first, the steam generator is not directly connected to the tunnel chamber. The storage chamber can collect and control the steam flow, so that the steam output from the storage chamber remains stable, thereby achieving a better cooking effect. The baffle plate in the storage chamber can guide and control the steam flow, prevent excessive air pressure in the storage chamber, and ensure the safe use of the storage chamber.

[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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0022] In one possible embodiment, please refer to Figure 1 and Figure 2 As shown, a steam storage and flow control device includes a tunnel chamber 1, a steam generator 2, and a gas supply pipe 3 connected to the steam generator 2. A storage chamber 4 is provided on one side of the tunnel chamber 1, and a first pressure gauge 5 is provided on the storage chamber 4. The gas supply pipe 3 is connected to the storage chamber 4. The steam generated by the steam generator 2 is input into the storage chamber 4 for storage. The pressure in the storage chamber 4 can be observed through the first pressure gauge 5. Several diversion pipes 6 are provided on the storage chamber 4, and several equally spaced air inlets 7 are provided on the side wall of the tunnel chamber 1. The diversion pipes 6 are connected to the air inlets 7 one by one. The steam stored in the storage chamber 4 is input into each air inlet 7 through the diversion pipes 6. The storage chamber 4 can collect and control the steam flow, so that the steam output from the storage chamber 4 remains stable, thereby obtaining a better cooking effect.

[0023] For further details, please refer to Figure 1 , Figure 2 and Figure 3 As shown, a pressure relief valve 20 is provided on one side of the storage chamber 4. When the pressure inside the storage chamber 4 is too high as observed by the first pressure gauge 5, the pressure relief valve 20 can be used to relieve the pressure in the storage chamber 4, thereby preventing damage to the storage chamber 4 due to excessive pressure. Each diversion pipe 6 is equipped with a valve 18 and a second pressure gauge 19. The flow of air is controlled by the valve 18, and the air pressure inside the tunnel chamber 1 can be observed by the second pressure gauge 19. The valve 18 is adjusted according to the second pressure gauge 19.

[0024] For further details, please refer to Figure 3 and Figure 4As shown, the inner wall of the storage cavity 4 is provided with a gradient insulation layer. The gradient insulation layer can effectively isolate heat transfer and provide excellent heat insulation effect. The gradient insulation layer includes a vacuum interlayer 22 and a heat insulation layer 23 located outside the vacuum interlayer 22. The heat insulation layer 23 is filled with rock wool. Rock wool has the characteristics of low thermal conductivity and high thermal resistance, which can effectively prevent heat transfer and ensure the temperature of the steam in the storage cavity 4. Together with the vacuum interlayer 22, it ensures the overall heat insulation efficiency of the storage cavity 4. The storage cavity 4 is provided with an inclined first guide plate 8 and a second guide plate 9. The first guide plate 8 and the second guide plate 9 are staggered. The first guide plate 8 and the second guide plate 9 can guide the steam, improve the stability of the steam flow, and avoid the direct impact of high-speed flowing steam on the inner wall of the storage cavity 4, thereby enhancing the service life of the storage cavity 4. At the same time, the inclined first guide plate 8 and the second guide plate 9 can block the steam, prevent the steam backflow, and ensure the stability of the steam pressure in the storage cavity 4.

[0025] For further details, please refer to Figure 1 , Figure 2 , Figure 3 and Figure 5 As shown, in another feasible embodiment, the length of the second guide plate 9 is adjustable. When the pressure in the storage cavity 4 is too high as observed by the first pressure gauge 5, the length of the second guide plate 9 is adjusted so that the second baffle plate abuts against the inner wall of the storage cavity 4, thereby blocking the steam and preventing the problem of excessive pressure caused by too much steam flowing into the storage cavity 4.

[0026] For further details, please refer to Figure 3 , Figure 5 and Figure 6As shown, the second guide plate 9 includes a mother plate 10 and a daughter plate 11 that slides with the mother plate 10. The mother plate 10 is fixedly connected to the inner wall of the storage cavity 4. A connecting plate 12 is provided on the daughter plate 11, and a protrusion 13 is fixedly connected to one side of the connecting plate 12. A sliding groove 21 that slides with the protrusion 13 is provided in the mother plate 10. Through the sliding engagement of the protrusion 13 and the sliding groove 21, the mother plate 10 can limit the daughter plate 11 to a certain extent, thereby preventing the daughter plate 11 from falling off the mother plate 10. The mother plate 10 slides out into the groove 21, allowing the daughter plate 11 to slide only along the groove 21. A limit mechanism is provided between the mother plate 10 and the daughter plate 11. The limit mechanism includes a limit block 14 that rotates with the connecting plate 12. A slot 15 is provided in the connecting plate 12 to engage with the limit block 14. A spring 16 is fixedly connected between the slot 15 and the limit block 14. A force groove 17 is provided at the upper end of the connecting plate 12. During normal use, the limit block 14 separates from the slot 15, at which point the daughter plate 11... Located within the mother plate 10, the lower surface of the limiting block 14 abuts against the surface of the storage cavity 4, thus limiting the sub-block within the storage cavity 4. At this time, steam can flow normally into the storage cavity 4. When the pressure inside the storage cavity 4 is too high as observed by the first pressure gauge 5, force is applied to the limiting block 14, causing it to engage in the slot 15. Simultaneously, the sub-plate 11 is pressed downwards. At this point, the lower end of the sub-plate 11 slides out of the mother plate 10 and abuts against the inner wall of the storage cavity 4, thus preventing steam from entering the storage cavity. The function of blocking steam: When the pressure in the storage chamber 4 decreases as observed by the first pressure gauge 5, the sub-plate 11 is pulled outward through the force groove 17. When the sub-plate 11 is pulled to a certain height, the limiting block 14 will rebound under the action of the spring 16, so that the lower end of the limiting block 14 abuts against the surface of the storage chamber 4 again, so that the storage chamber 4 re-limits the sub-plate 11, thereby ensuring the stability of the installation of the sub-plate 11 and allowing steam to pass smoothly into the storage chamber 4.
