Description

Technical Field

[0001] This utility model relates to the field of steam preparation technology, and specifically to a large-capacity steam generator. Background Technology

[0002] A large-capacity steam generator is a device that can generate steam by heating. It has a wide range of applications in manufacturing, daily life, medical equipment and other technical fields.

[0003] Large-capacity steam generators typically consist of a vertical tubular structure comprising a water tank, a heater, and a steam chamber. The heater is vertically installed inside the water tank, while the steam chamber is located above and connected to the water tank. Because the heater is vertically installed, to avoid compromising the overall strength of the steam evaporator, the heater's inlet is usually located at the bottom of the water tank. During maintenance and replacement, the water tank must be laid horizontally before the heater can be removed, making maintenance and replacement inconvenient. Furthermore, due to the vertical tubular structure and the relatively long length of the heater, the steam chamber of large-capacity steam generators is often smaller to accommodate equipment, workshops, or indoor environments with limited height. This results in a rapid pressure rise during operation, requiring frequent depressurization or shutdown to prevent the large-capacity steam generator from bursting. Utility Model Content

[0004] To overcome the shortcomings of the existing technology, the purpose of this utility model is to invent a large-capacity steam generator that is easy to install, has a large steam capacity, and can be adapted to complete equipment, factories, or indoor spaces with insufficient height space.

[0005] The present invention adopts the following technical solution:

[0006] A large-capacity steam generator, comprising:

[0007] A water tank, wherein a receiving cavity is provided inside the water tank;

[0008] A plurality of heaters are placed horizontally within the receiving cavity and are parallel to each other;

[0009] Several mounting joints are provided at the same end of the water tank for mounting the heater;

[0010] The water inlet is located at the other end of the water tank and communicates with the receiving cavity;

[0011] A steam cylinder is located at the upper end of the water tank and communicates with the receiving cavity. A steam outlet is provided at the upper end of the steam cylinder.

[0012] Furthermore, a fixing plate is provided at intervals inside the receiving cavity, and an opening is provided on the fixing plate for the heater to pass through, and the outer wall of the heater is in contact with the inner wall of the opening.

[0013] Furthermore, the steam cylinder consists of a cylinder body and a hemispherical cap disposed at the upper end of the cylinder body, and the steam outlet is disposed at the upper end of the cap.

[0014] Furthermore, the water tank includes a circular tube and hemispherical circular tube caps disposed at both ends of the circular tube, the two circular tube caps being sealed to the circular tube.

[0015] Furthermore, it also includes a temperature detector for detecting the temperature inside the steam cylinder, and the upper end of the steam cylinder is provided with a temperature detection connector for installing the temperature detector.

[0016] Furthermore, it also includes a water level detection sensor for detecting the water level in the steam cylinder and the water tank, and a water level detection connector for installing the water level detection sensor is also provided on the outside of the steam cylinder and the water tank.

[0017] Furthermore, it also includes a drain outlet, which is located at the lower end of the water tank and communicates with the receiving cavity.

[0018] Furthermore, it also includes two support frames, which are spaced apart at the lower end of the water tank.

[0019] Furthermore, it also includes a protection device, which includes a pressure relief valve and a negative pressure valve.

[0032] like Figure 1-3 As shown, a large-capacity steam generator includes:

[0033] Water tank 10, wherein a receiving cavity 103 is provided inside the water tank 10;

[0034] A plurality of heaters are placed horizontally within the receiving cavity 103 and are parallel to each other;

[0035] Several mounting joints 20 are provided at the same end of the water tank 10 for mounting the heater;

[0036] The water inlet 30 is located at the other end of the water tank 10 and is connected to the receiving cavity 103;

[0037] A steam cylinder 40 is disposed at the upper end of the water tank 10 and communicates with the receiving cavity 103. A steam outlet 403 is provided at the upper end of the steam cylinder 40.

[0038] During operation, water enters the receiving cavity 103 through the inlet 30. At this time, the heater installed in the receiving cavity 103 will heat the water in the receiving cavity 103. After the water is heated, it turns into steam and enters the steam cylinder 40 and is discharged from the steam outlet 403.

[0039] This invention places the heater horizontally within the receiving cavity 103 and positions the steam cylinder 40 above the water tank 10. This design facilitates heater installation and maintenance while reducing the vertical space required by the heater. This allows for increased steam capacity without increasing the overall height of the device, making it suitable for equipment, factories, or indoor spaces with limited height. Furthermore, by centrally positioning several mounting connectors 20 at the same end of the water tank 10, the invention facilitates unified replacement and maintenance by staff. This also reduces the required operating space, eliminating the need to reserve space at the other end of the water tank 10 for replacement and maintenance. If the mounting connectors 20 were installed at both ends of the water tank 10, operating space would be required for installing and replacing the heating elements, increasing the working space of the large-capacity steam generator. Therefore, to reduce the working space occupied by the large-capacity steam generator, all mounting connectors 20 are installed at the same end of the water tank 10. Staff only need to provide operating space at the end of the water tank 10 with the mounting connectors 20; the other end can be used to install other equipment or be placed against a wall.

[0040] Meanwhile, in order to prevent the heater from shaking in the receiving cavity 103 and improve the stability of the heater, in this embodiment, fixing plates 104 are provided at intervals in the receiving cavity 103. The fixing plates 104 have openings for the heater to pass through, and the outer wall of the heater is in contact with the inner wall of the opening.

[0041] In order to prevent the fixing plate 104 from scratching the heater, a rubber pad is provided on the inner wall of the opening in this embodiment, so that the fixing plate 104 and the heater can make soft contact, thereby effectively preventing the fixing plate 104 from scratching or damaging the heater.

[0042] In addition, to enhance the compressive strength of the steam cylinder 40, in this embodiment, the steam cylinder 40 is composed of a cylinder body 401 and a hemispherical cap 402 disposed on the upper end of the cylinder body 401. The steam outlet 403 is disposed on the upper end of the cap 402. The hemispherical cap 402 has strong compressive strength and can effectively reduce the probability of deformation of the steam cylinder 40 during operation.

[0043] Meanwhile, in order to enhance the overall strength of the water tank 10, in this embodiment, the water tank 10 includes a circular tube 101 and a circular tube cover 102 disposed at both ends of the circular tube 101 and in a hemispherical shape. The two circular tube covers 102 are sealed to the circular tube 101. The hemispherical circular tube cover 102 has strong compressive strength and can effectively reduce the probability of the water tank 10 deforming under pressure.

[0044] In order to facilitate the staff to obtain the internal temperature of the large-capacity steam generator in real time, this embodiment also includes a temperature detector for detecting the temperature inside the steam cylinder 40, and a temperature detection connector 50 for installing the temperature detector is provided at the upper end of the steam cylinder 40.

[0045] In addition, to prevent the water level in the water tank 10 from being too high and to prevent a large amount of water from entering the steam cylinder 40, which would cause the pressure inside the large-capacity steam generator to be too high, this embodiment also includes a water level detection sensor for detecting the water level in the steam cylinder 40 and the water tank 10. A water level detection connector 60 for installing the water level detection sensor is also provided on the outside of the steam cylinder 40 and the water tank 10.

[0046] In order to facilitate the discharge of scale and dirt accumulated in the water tank 10, a drain outlet 70 is also provided in this embodiment. The drain outlet 70 is located at the lower end of the water tank 10 and communicates with the receiving cavity 103.

[0047] Meanwhile, to facilitate the connection of the sewage pipe to the sewage outlet 70 by the staff, two support frames 80 are also provided in this embodiment. The two support frames 80 are spaced apart at the lower end of the water tank 10, thereby lifting the water tank 10 to provide space for the installation of the sewage pipe.

[0048] In addition, to prevent the steam cylinder 40 and water tank 10 from rupturing due to excessive internal pressure during operation, the large-capacity steam generator in this embodiment is also equipped with a protection device 90. This protection device 90 includes a pressure relief valve and a negative pressure valve connected to an external water pump. A pressure relief valve connector 901 and a negative pressure valve connector 902 for installing the pressure relief valve are provided at the upper end of the water tank 10. When the pressure inside the steam cylinder 40 and water tank 10 exceeds a preset value, the negative pressure valve operates, and water vapor is discharged from the steam cylinder 40 and water tank 10 to reduce the pressure inside the steam cylinder 40 and water tank 10. At the same time, the external water pump will draw water vapor discharged from the negative pressure valve to prevent pipe blockage. When the negative pressure valve fails to reduce the pressure inside the steam cylinder 40 and water tank 10 normally or completely, the pressure inside the steam cylinder 40 and water tank 10 continues to rise until it reaches the maximum pressure value. At this point, the pressure relief valve operates to release the pressure inside the steam cylinder 40 and water tank 10.

[0049] Furthermore, to facilitate real-time monitoring of the pressure inside the steam cylinder 40 and water tank 10, and to ensure timely notification when the pressure exceeds preset values, this embodiment also includes a pressure gauge for detecting the pressure inside the steam cylinder 40 and water tank 10, and a pressure switch for communicating with an external alarm. The outer side of the steam cylinder 40 is also equipped with a pressure gauge connector 110 for installing the pressure gauge and a pressure switch connector 120 for installing the pressure switch. During use, staff can observe the pressure gauge reading to obtain the real-time pressure inside the steam cylinder 40 and water tank 10. When the pressure inside the steam cylinder 40 and water tank 10 exceeds the preset value, the pressure switch will control the external alarm to sound, alerting the staff.

[0050] The above description, in conjunction with specific embodiments, provides a further detailed explanation of the present utility model. It should not be construed that the specific implementation of the present utility model is limited to these descriptions. For those skilled in the art, several simple deductions or substitutions can be made without departing from the concept of the present utility model, and all such deductions or substitutions should be considered to fall within the scope of protection defined by the claims submitted by the present utility model.
