Description

Technical Field

[0001] The utility model relates to the technical field of separators, in particular to a novel sealing groove structure for the cover of a dish machine bowl. Background Art

[0002] At present, disc separators have been widely used in industries such as medicine, chemical industry, beverage, and environmental protection. They have the characteristics of continuous, rapid, and good separation effect for liquid-liquid, liquid-solid, and liquid-liquid-solid separation and clarification. With the increasing automation degree of customers, higher requirements are also put forward for the automatic operation of disc separators. Obviously, automatic slag-discharging disc machines are increasingly favored by users. However, due to the frequent slag-discharging process of automatic slag-discharging disc machines, seal failure often occurs, which in turn causes problems such as non-slag-discharging and non-sealing. More seriously, it leads to excessive vibration in the overall operation of the disc machine, resulting in a reduction in the service life of the entire disc machine. The reasons for the above problems are basically centered around the seal failure of the sealing ring on the cover of the disc machine bowl. The reasons for the failure of this sealing ring are often due to the cyclic operation of separation and slag-discharging actions and the influence of gravity with the sealing groove opening downward, resulting in the dropping or deformation of the sealing ring. Obviously, the frequent occurrence of the above problems has a great impact on the use of the disc machine itself, increasing the maintenance cost of the disc machine and the additional cost of users. Therefore, a novel sealing groove structure for the cover of a disc machine bowl is proposed. Summary of the Utility Model

[0003] The purpose of the utility model is to propose a novel sealing groove structure for the cover of a disc machine bowl to solve the above problems.

[0004] To achieve the above purpose, the utility model provides the following technical solution: a novel sealing groove structure for the cover of a disc machine bowl, including a bowl cover and a sealing groove arranged on the bowl cover with an opening downward; it is characterized in that it further includes a sealing ring installed in the sealing groove, a sealing card slot for preventing the sealing ring from falling off is arranged on the sealing groove, and a sealing snap ring adapted to the sealing card slot is arranged on the sealing ring.

[0005] Further preferably, one side of the sealing snap ring is provided with a guiding inclined surface, and the other side is provided with a retaining surface; the lower side of the guiding inclined surface is attached to the outer circle of the sealing ring.

[0006] Further preferably, a retaining ring for positioning and buffering is also arranged on the sealing ring at one end protruding from the sealing groove.

[0007] The beneficial effects of the utility model: By arranging a sealing card slot in the sealing groove and a sealing snap ring adapted to the sealing groove on the sealing ring, the cooperation of the sealing snap ring and the sealing card slot limits the up and down position of the sealing ring in the sealing groove, avoiding the sealing ring from falling out of the sealing groove due to its own gravity, thereby avoiding the problem of seal failure.

[0012] Next, we will further explain a new sealing groove structure of the bowl cover of a dish machine according to the present utility model with reference to the accompanying drawings.

[0013] It should be noted that all directional indications such as up, down, left, right, front, back... in the embodiments of the present utility model are only used to explain the relative positional relationship and movement conditions between components in a specific posture as shown in the accompanying drawings. If this specific posture changes, then the directional indications will also change accordingly.

[0014] In the present utility model, unless otherwise clearly specified and defined, terms such as "connection" and "fixation" should be understood in a broad sense; for example, "fixation" can be a fixed connection, a detachable connection, or integrated; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the internal communication of 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 circumstances.

[0015] Referring to Figures 1-3 as shown in, a new sealing groove structure of the bowl cover of a dish machine includes a bowl cover 1 and a sealing groove 2 provided on the bowl cover 1 and opening downward; the feature is that it further includes a sealing ring 3 installed in the sealing groove 2, a sealing card slot 4 for preventing the sealing ring 3 from falling off is provided on the sealing groove 2, and a sealing snap ring 5 adapted to the sealing card slot 4 is provided on the sealing ring 3;

[0016] By providing a sealing card slot 4 in the sealing groove 2 and a sealing snap ring 5 adapted to the sealing groove 2 on the sealing ring 3, the cooperation of the sealing snap ring 5 and the sealing card slot 4 limits the up and down position of the sealing ring 3 in the sealing groove 2, avoiding the sealing ring 3 from falling out of the sealing groove 2 due to its own gravity, thereby avoiding the problem of sealing failure.

[0017] In one embodiment, a guiding inclined surface 6 is provided on one side of the sealing snap ring 5, and an anti-retreat surface 7 is provided on the other side; the lower side of the guiding inclined surface 6 is in contact with the outer circle of the sealing ring 3;

[0018] Through the setting of the guiding inclined surface 6, and its lower end being in contact with the outer circle of the sealing ring 3, when the sealing ring 3 is installed into the sealing groove 2, it forms an extrusion on the sealing snap ring 5 along the guiding inclined surface 6, enabling it to extend into the sealing groove 2 until it moves to the sealing snap groove 4 and is stuck in the sealing snap groove 4, avoiding interference of the sealing snap ring 5 with the installation of the sealing ring 3;

[0019] Through the setting of the anti-retreat surface 7, in cooperation with the sealing snap groove 4, it plays a role in blocking and interfering with the outward movement of the sealing ring 3, avoiding the sealing ring 3 from disengaging from the sealing groove 2.

[0020] In one embodiment, a retaining ring 8 for positioning and buffering is further provided on the sealing ring 3 at one end protruding from the sealing groove 2; through the setting of the retaining ring 8, when installing the sealing ring 3, when the retaining ring 8 is in contact with the bottom of the bowl cover 1, it indicates that the sealing ring 3 has been installed in place and the sealing snap ring 5 has been stuck in the sealing snap groove 4; during the process of the piston moving up and down during the automatic slag discharge of the dish machine, it contacts and forms an extrusion with the retaining ring 8, playing a buffering role and at the same time squeezing the sealing ring 3 through the extrusion force of the piston, further ensuring the sealing performance during the separation process, and thus ensuring the automatic slag discharge action of the dish machine, enabling the dish machine to operate stably.

[0021] The protection scope of the present utility model is not limited to the above embodiments and their variations. Routine modifications and replacements made by those skilled in the art based on the content of this embodiment all fall within the protection scope of the present utility model.
