Technical Field

[0001] This utility model belongs to the field of methanol technology, specifically relating to a methanol fuel valve assembly. Background Technology

[0002] Currently, the global shipping industry is accelerating its decarbonization process, entering a fuel transition phase and rapidly moving towards low-carbon development. Methanol, as a new type of alternative marine fuel, is receiving increasing attention, and the research and development and promotion of corresponding marine methanol engines and related products are progressing steadily. Our company is also actively collaborating with customers to develop related FVU methanol fuel valve assembly products. Engines use methanol supplied under specific temperature conditions, with a fixed supply pressure and flow rate depending on the engine load. The methanol fuel supply system must provide fuel to the engine while meeting temperature, flow rate, pressure, and performance requirements.

[0003] Chinese patent publication number CN 113711710 B discloses a valve group unit for a marine methanol boiler, including a first three-way valve, a second three-way valve, a third three-way valve, a first straight-through valve, a second straight-through valve, a second check valve, a first check valve, a flow regulating valve, a temperature sensor, a first pressure sensor, and a second pressure sensor; the valve group can realize the functions of operating flow control, nitrogen replacement, methanol fuel cut-off, and equipment shutdown through the logic control of valve positions.

[0004] However, the current valve group unit for marine methanol boilers has the following problems: the force-bearing block cannot use the force it receives to drive the movement of the separation plate, which makes it impossible to achieve the shaking of the separation plate, the screening of impurities, and the anti-clogging effect. Therefore, we propose a methanol fuel valve group. Utility Model Content

[0005] The purpose of this invention is to provide a methanol fuel valve assembly that can solve the problem in related technologies where the force-bearing block cannot use the force it receives to drive the movement of the separation plate, resulting in the inability to achieve the shaking of the separation plate, the inability to screen impurities, and the inability to achieve the anti-clogging effect.

[0006] The specific technical solution adopted by this utility model is as follows:

[0007] A methanol fuel valve assembly includes a base plate and a central box. The central box is located on top of the base plate. An inlet pipe and an outlet pipe are provided on the side of the central box. An anti-clogging device is provided inside the central box. The anti-clogging device includes a fixing plate, which is fixedly connected to the inner wall of the central box. A motor is located at the bottom of the fixing plate. A rotating shaft is fixedly connected to the end of the output shaft of the motor. A rotating plate is fixedly connected to the circumferential surface of the rotating shaft. A blocking block is fixedly connected to the circumferential surface of the rotating plate.

[0008] Preferably, the inner wall of the central box is provided with a rectangular groove, one end of a spring is fixedly connected to the inner wall of the rectangular groove, a separation plate is fixedly connected to the end of the spring away from the inner wall of the rectangular groove, and a force-bearing block is fixedly connected to the bottom of the separation plate. This design is beneficial for the separation plate to separate impurities.

[0009] Preferably, the rectangular groove is located on the movement trajectory of the separating plate, the separating plate is slidably connected to the inner wall of the rectangular groove, and one end of the force-bearing block is set as an arc surface. This design is beneficial for the force-bearing block to be able to receive force and drive the separating plate to move upward.

[0010] Preferably, the central box is provided with a feeding device, which includes a partition plate. The partition plate is fixedly connected to the inner wall of the central box. A through groove is formed on the top of the partition plate, and a sliding groove is formed on the top of the partition plate. One end of a force-bearing spring is fixedly connected to the inner wall of the sliding groove. A slider is fixedly connected to the end of the force-bearing spring away from the sliding groove. A baffle is fixedly connected to the side of the slider. This design is beneficial for the slider to slide on the inner wall of the sliding groove under force.

[0011] Preferably, a force-bearing ring is fixedly connected to the circumferential surface of the rotating shaft, and an action plate is fixedly connected to the circumferential surface of the force-bearing ring. This design is beneficial for the action plate to be able to bear force and move with the force-bearing ring.

[0012] Preferably, the force-bearing ring is located above the partition, the size of the baffle is adapted to the size of the through groove, and one end of the action plate is set as an arc surface. This design helps the baffle to block the through groove.

[0013] Preferably, one end of the blocking block is set as an arc surface, and the number of the blocking blocks is set to several and arranged in a circumferential array on the circumferential surface of the rotating plate. The rotating shaft passes through the bottom of the separation plate and the partition plate. This design is beneficial to the fact that the rotating shaft will not obstruct the separation plate and the partition plate when it moves.

[0014] The technical effects achieved by this utility model are as follows:

[0015] 1. This utility model, through the setting of the anti-blocking device, causes the force-bearing block to slide upward on the inner wall of the rectangular groove under the force, and when the blocking block continues to move until it no longer contacts the force-bearing block, the force-bearing block loses its force and causes the separation plate to reset by the elastic force of the spring, thereby realizing the shaking of the separation plate. This not only achieves the function of screening impurities, but also achieves the effect of anti-blocking.

[0016] 2. By setting up a feeding device, this utility model allows the action plate to rotate continuously until it no longer contacts the slider. When the slider loses its thrust, it can be reset by the elastic force of the force spring, so that the baffle no longer blocks the passage. This allows the baffle to open the passage intermittently, allowing the material to enter the next layer intermittently, and enabling the material to be screened evenly. Attached Figure Description

[0024] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.

[0025] like Figure 1-3As shown, a methanol fuel valve assembly includes a base plate 1 and a central box 2. The central box 2 is located on the top of the base plate 1. A feed pipe 3 and a discharge pipe 4 are provided on the side of the central box 2. An anti-blocking device 5 is provided inside the central box 2. The anti-blocking device 5 includes a fixing plate 51, which is fixedly connected to the inner wall of the central box 2. A motor 52 is provided at the bottom of the fixing plate 51. A rotating shaft 53 is fixedly connected to the end of the output shaft of the motor 52. A rotating plate 54 is fixedly connected to the circumferential surface of the rotating shaft 53. A blocking block 55 is fixedly connected to the circumferential surface of the rotating plate 54.

[0026] A rectangular groove 56 is provided on the inner wall of the central box 2. One end of a spring 57 is fixedly connected to the inner wall of the rectangular groove 56. A separation plate 58 is fixedly connected to the end of the spring 57 away from the inner wall of the rectangular groove 56. A force-bearing block 59 is fixedly connected to the bottom of the separation plate 58. This design is beneficial for the separation plate 58 to separate impurities.

[0027] The rectangular groove 56 is located on the movement trajectory of the separating plate 58. The separating plate 58 is slidably connected to the inner wall of the rectangular groove 56. One end of the force block 59 is set as an arc surface. This design is conducive to the force block 59 being able to receive force and drive the separating plate 58 to move upward.

[0028] Based on the above structure, when methanol material is transported and flows, it needs to be screened to remove impurities and ensure that the material transport is not blocked. When the operator turns on the external power, the motor 52 is started, which makes the rotating shaft 53 rotate, causing the rotating plate 54 to rotate under force, and driving the block 55 fixed on the top of the rotating plate 54 to rotate under force, forcing the block 55 to come into contact with the force block 59. The force block 59 then drives the separation plate 58 to slide upward on the inner wall of the rectangular groove 56. When the block 55 continues to move until it no longer comes into contact with the force block 59, the force block 59 loses force and drives the separation plate 58 to reset using the elastic force of the spring 57, realizing the shaking of the separation plate 58. This not only achieves the function of screening impurities, but also achieves the effect of preventing blockage.

[0029] like Figure 4-5 As shown, a feeding device 6 is provided inside the central box 2. The feeding device 6 includes a partition 61, which is fixedly connected to the inner wall of the central box 2. A through groove 62 is provided on the top of the partition 61, and a sliding groove 63 is provided on the top of the partition 61. One end of a force spring 64 is fixedly connected to the inner wall of the sliding groove 63. A slider 65 is fixedly connected to the end of the force spring 64 away from the sliding groove 63. A baffle 66 is fixedly connected to the side of the slider 65. This design is beneficial for the slider 65 to slide on the inner wall of the sliding groove 63 under force.

[0030] A force-bearing ring 67 is fixedly connected to the circumferential surface of the rotating shaft 53, and an action plate 68 is fixedly connected to the circumferential surface of the force-bearing ring 67. This design is beneficial to the action plate 68 being able to receive force and move with the force-bearing ring 67.

[0031] The force-bearing ring 67 is located above the partition plate 61. The size of the baffle 66 is adapted to the size of the through groove 62. One end of the action plate 68 is set as an arc surface. This design is conducive to the baffle 66 blocking the through groove 62.

[0032] One end of the block 55 is set as an arc surface. There are several blocks 55, which are arranged in a circumferential array on the circumferential surface of the rotating plate 54. The rotating shaft 53 passes through the bottom of the separating plate 58 and the partition plate 61. This design is beneficial to the fact that the rotating shaft 53 will not obstruct the separating plate 58 and the partition plate 61 when it moves.

[0033] According to the above structure, when methanol material enters the central box 2, in order to enable the separation plate 58 to screen the material evenly, when the rotating shaft 53 rotates, the force ring 67 fixed on the circumferential surface of the rotating shaft 53 also rotates. The force ring 67 can drive the action plate 68 to move, forcing the action plate 68 to contact one end of the slider 65, forcing the slider 65 to drive the baffle 66 to slide on the inner wall of the chute 63, so that the baffle 66 blocks the through groove 62. When the action plate 68 continues to rotate until it no longer contacts the slider 65, the slider 65 loses its thrust and can be reset by the elastic force of the force spring 64, so that the baffle 66 no longer blocks the through groove 62, which allows the baffle 66 to open the through groove intermittently, allowing the material to enter the next layer intermittently, and enabling the material to be screened evenly.

[0034] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the field.
