[0002] Impurities often block the filter inside the external pressure circuit pipeline of the on-site giant tire vulcanizer, such as rubber edges, sludge, iron filings, etc. The blocked impurities in the filter will prevent the external pressure steam from being discharged, resulting in high external pressure, and the vulcanization process cannot be satisfied, leading to defective finished tires.

[0003] When the external pressure is high due to the blocked impurities in the filter, personnel usually open the bypass ball valve of the external pressure circuit to discharge the external pressure steam. However, the above method has the problem of steam waste and leakage, the energy cost of the department cannot be reduced, and the impurities in the filter need to be regularly cleaned by personnel, resulting in high labor intensity.

[0008] Furthermore, the air inlet is connected to an air inlet cavity. The air inlet cavity and the storage cavity are respectively located at both ends of the filter screen. The external pressure steam drives the impurities to enter the filter body from the air inlet, pass through the air inlet cavity and the outlet on the filter screen, and then enter the storage cavity.

[0009] Furthermore, a closed cavity is provided between the filter screen and the inner wall of the filter body. An air outlet is provided on the closed cavity to discharge the external pressure steam that has passed through the filter screen and entered the closed cavity.

[0020] Hereinafter, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative efforts fall within the protection scope of the present utility model.

[0021] In this document, terms such as "upper", "lower", "left", "right", "top", etc. that indicate orientations or positional relationships are based on the orientations or positional relationships shown in the accompanying drawings and are only for the convenience of describing the present invention and simplifying the description. They do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0022] like Figures 1 to 3 As shown, a self-cleaning device for a vulcanizing machine filter includes a storage chamber 1 for collecting impurities. The storage chamber 1 is located at one end of a filter body 2 away from an air inlet. The storage chamber 1 is connected to a discharge channel 3 extending to the outside of the filter body 2. A valve is provided on the discharge channel 3 to control the discharge of impurities in the storage chamber 1.

[0023] By setting a storage chamber 1 in the filter body 2, impurities in the external pressure steam entering from the air inlet are collected, thereby preventing impurities from clogging the filter body 2 and affecting the normal operation of the filter, making it difficult to discharge the external pressure steam and causing the external pressure to be too high to affect the vulcanization process. When it is necessary to clean the impurities, open the valve on the discharge channel 3 connected to the storage chamber 1, and the impurities are discharged along the discharge channel 3 under the pressure of the external pressure steam, which is convenient for cleaning and does not affect the normal discharge of steam from the filter outlet.

[0024] The self-cleaning state of the filter in this embodiment can make the filter meet the requirements of the on-site vulcanization process and prevent defective finished tires caused by high external pressure due to impurities blocking the filter. At the same time, compared with the prior art where only the bypass pipe can be opened for exhaust after the filter is blocked, a storage chamber 1 specifically for collecting impurities is provided, which does not affect the normal exhaust of the filter outlet, eliminates the waste of steam caused by opening the bypass of the external pressure circuit, and reduces the energy cost of the department.

[0025] The vulcanizer filter self-cleaning device of this embodiment further includes a filter screen 4 fixedly installed in the filter body 2 , and an outlet 5 is provided on a side of the filter screen 4 close to the storage chamber 1 to connect with the storage chamber 1 to facilitate impurities to enter the storage chamber 1 .

[0026] Specifically, a filter screen 4 is provided to filter the external pressure steam in the filter so that the steam discharged through the filter outlet meets the emission requirements. At the same time, an opening 5 is provided at the bottom of the filter screen 4 so that impurities can pass through the filter screen 4 driven by the external pressure steam and enter the storage chamber 1 for collection, thereby avoiding clogging of the filter.

[0027] Preferably, the filter screen 4 is in the shape of a hollow cylinder with openings at both the top and the bottom. It is vertically arranged inside the filter body 2. The air inlet is arranged above the filter screen 4. The external pressure steam enters the filter body 2 through the air inlet and flows downward. The impurities fall due to their own weight and pass through the opening at the bottom of the filter screen 4 to reach the storage cavity 1 for collection, thus preventing the impurities from clogging the mesh holes of the filter screen 4 and enabling the external pressure steam to pass through the filter screen 4 and the air outlet to discharge from the filter body 2.

[0028] In the self-cleaning device of the vulcanizer filter of this embodiment, the air inlet is communicated with the air inlet cavity 6. The air inlet cavity 6 and the storage cavity 1 are respectively located at both ends of the filter screen 4. The external pressure steam drives the impurities to enter the filter body 2 from the air inlet, pass through the air inlet cavity 6 and the outlet 5 on the filter screen 4, and enter the storage cavity 1.

[0029] Specifically, an air inlet pipe 11 is arranged outside the air inlet. The external pressure steam enters the air inlet cavity 6 at the top inside the filter body 2 through the air inlet pipe 11 for buffering. The air inlet cavity 6 guides the air flow downward through the filter screen 4 and facilitates the impurities to fall into the storage cavity 1.

[0030] In the self-cleaning device of the vulcanizer filter of this embodiment, a closed cavity 7 is arranged between the filter screen 4 and the inner wall of the filter body 2. An air outlet is arranged on the closed cavity 7 to discharge the external pressure steam that has passed through the filtration of the filter screen 4 and entered the closed cavity 7.

[0031] Specifically, the closed cavity 7 surrounding the side surface of the filter screen 4 is set to separate the external pressure steam filtered by the filter screen 4 from the external pressure steam with impurities, so that the filtered air flow enters the closed cavity 7 and is smoothly guided to discharge through the air outlet, thus ensuring the filtering effect of the filter screen 4.

[0032] Preferably, an air outlet pipe 12 is arranged outside the air outlet. The air outlet pipe 12 and the air inlet pipe 11 are respectively arranged on the left and right sides of the filter body 2 and have a certain height difference, which is convenient for the installation of the filter screen 4 inside the filter body 2, thereby guiding the air flow to flow inside the filter body 2 and enabling the impurities to fall.

[0033] Specifically, in this embodiment, the discharge channel 3 is arranged perpendicular to the air inlet pipe 11 and the air outlet pipe 12. Additionally, it can also be as Figure 3 described, the discharge channel 3 is arranged parallel to the air inlet pipe 11 and the air outlet pipe 12. The setting of the discharge channel 3 is selected according to the laying requirements of the pipeline in specific situations.

[0034] In addition, a cover plate 10 is detachably installed on the top of the filter body 2. The cover plate 10 is set to seal the inside of the filter body 2 to prevent the leakage of the external pressure steam. At the same time, it is convenient to open the cover plate 10 to inspect and repair the inside of the filter body 2.

[0035] In the self-cleaning device of the vulcanizer filter of this embodiment, a first sealing ring 8 and a second sealing ring 9 are respectively arranged between the two ends of the filter screen 4 and the filter body 2, and the closed cavity 7 is located between the first sealing ring 8 and the second sealing ring 9.

[0036] Specifically, the upper surface of the first sealing ring 8 is close to the lower edge of the air inlet to prevent the external pressure steam with impurities from entering and accumulating between the inner wall of the filter body 2 and the filter screen 4. The second sealing ring 9 is close to the bottom end of the filter body 2, which is convenient for impurities to concentrate in the storage cavity 1 and makes full use of the space inside the filter screen, making the overall structure of the filter more compact.

[0037] In the self-cleaning device of the vulcanizer filter of this embodiment, the bottom of the filter body 2 is in a conical structure, so that the storage cavity 1 is in a funnel shape, and a discharge port communicating with the discharge channel 3 is opened at the center of the bottom of the storage cavity 1.

[0038] Through the above settings, it is convenient for impurities to converge towards the discharge port in the storage cavity 1. Thus, when the valve is opened, the impurities can move along the inclined surface towards the discharge channel 3, making the discharge more thorough and improving the self-cleaning effect of the filter.

[0039] In the self-cleaning device of the vulcanizer filter of this embodiment, the valve is signal-connected to the control unit, and the control unit controls the opening time interval and duration of the valve according to the setting.

[0040] Controlling the opening and closing of the valve through the PLC reduces the burden on the staff, reduces the risk of scalding the operators, and reduces the labor intensity of the personnel.

[0041] In the present utility model, unless otherwise clearly defined and limited, terms such as "installation", "setting", "connection", "fixation", "rotation" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or integrated; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, and it can be the communication inside two components or the interaction relationship between two components. Unless otherwise clearly defined, for those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific situations.

[0042] Although the embodiments of the present utility model have been shown and described in detail, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and deformations can be made to these embodiments without departing from the principles and spirits of the present utility model. The scope of the present utility model is defined by the appended claims and their equivalents.
