Description

Technical Field

[0001] This utility model relates to a pressure kneading device for producing a calcium bromide-resistant sheath for drilling cables. Background Technology

[0002] In some drilling environments, cables may come into contact with solutions containing calcium bromide or other chemicals. Calcium bromide is a commonly used drilling fluid treatment agent and is corrosive. If the cable sheath does not have resistance to calcium bromide corrosion, it may cause damage to the sheath, affecting the normal use of the cable and even leading to safety accidents. Therefore, resistance to calcium bromide corrosion is one of the essential characteristics that drilling cable sheath materials must possess.

[0003] In the production process of drilling cables, the kneading process of the sheath material is crucial. Existing kneading devices have poor heat dissipation and are difficult to control the temperature during the kneading process, thus affecting the performance and quality of the sheath material. In view of this, this utility model proposes a pressure kneading device for the production of calcium bromide resistant sheaths for drilling cables to solve the above problems. Utility Model Content

[0013] As an improvement to the above technical solution, a pump body is provided on the top plate, the pump body is connected to the inner cavity of the storage shell, and the connecting hose is connected to the pump body.

[0014] As an improvement to the above technical solution, the two sets of storage housings are matched with the positions of the two sets of guide rods, and the guide rods are disposed in the inner cavity of the storage housing;

Detailed Implementation

[0028] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] Example:

[0030] like Figure 1-6 As shown, this embodiment proposes a pressure kneading device for producing a calcium bromide resistant sheath for drilling cables, including a pressure kneading machine 10, wherein the pressure kneading machine 10 is provided with a kneading shell 11, and a sealing cover 50 is provided on the kneading shell 11.

[0031] The pressure kneading machine 10 is provided with a base plate 14, on which two sets of support plates 12 are provided. The kneading shell 11 is located between the two sets of support plates 12. A top plate 13 is provided on the two sets of support plates 12. A lifting assembly 40 is provided on the top plate 13. The lifting assembly 40 is connected to a sealing cover 50. A heat dissipation cavity 51 for coolant flow is provided inside the sealing cover 50. The lifting assembly 40 drives the sealing cover 50 to close onto the kneading shell 11, so that the heat dissipation cavity 51 contacts the kneading shell 11 to perform the heat dissipation process.

[0032] In this embodiment, when the drilling cable calcium bromide resistant sheath material is produced, the material is introduced into the kneading shell 11. Then, the lifting component 40 drives the sealing cover 50 to descend until the sealing cover 50 seals the top opening of the kneading shell 11. Then, coolant is introduced into the heat dissipation cavity 51. During the meshing process, heat dissipation is carried out through the heat dissipation cavity 51.

[0033] By setting up a pressure kneader 10, a kneading shell 11, a sealing cover 50, a bottom plate 14, a support plate 12, a top plate 13, a lifting assembly 40, and a heat dissipation cavity 51 inside the sealing cover 50, the material can be effectively kneaded during the production of calcium bromide resistant sheathing material for drilling cables. At the same time, the heat dissipation cavity 51 can dissipate heat from the kneading shell 11, preventing the material from being damaged due to excessive temperature. This ensures the performance and quality of the sheathing material, thereby improving production efficiency and product quality.

[0034] Specifically, the lifting assembly 40 includes a drive cylinder 41, and the piston rod of the drive cylinder 41 is connected to the sealing cover 50;

[0035] The sealing cover 50 is also provided with two sets of guide rods 42, which are slidably mounted on the top plate 13.

[0036] In this embodiment, the guide rod 42 and the top plate 13 are slidably sealed together.

[0037] In this embodiment, the drive cylinder 41 facilitates the lifting and lowering of the sealing cover 50 to seal and dissipate heat from the kneading housing 11.

[0038] Specifically, the top plate 13 is provided with two sets of storage housings 30, and the storage housings 30 are provided with connecting hoses 21. The two sets of connecting hoses 21 are respectively connected to the two ends of the sealing cover 50.

[0039] The connecting hose 21 is connected to the inner cavity of the heat dissipation cavity 51.

[0040] In this embodiment, coolant is provided in the storage housing 30 and introduced into the heat dissipation cavity 51 through the connecting hose 21, so that the coolant in the heat dissipation cavity 51 flows continuously to dissipate heat.

[0041] Specifically, the top of the heat dissipation cavity 51 is provided with multiple sets of first baffles 52, and the bottom of the heat dissipation cavity 51 is provided with multiple sets of second baffles 53, with the first baffles 52 and the second baffles 53 being arranged alternately.

[0042] In this embodiment, the first baffle 52 does not contact the bottom end of the heat dissipation cavity 51, and the second baffle 53 does not contact the top end of the heat dissipation cavity 51.

[0043] By setting multiple sets of first baffles 52 at the top end and multiple sets of second baffles 53 at the bottom end of the heat dissipation cavity 51, and by staggering the first baffles 52 and the second baffles 53, the flow path and residence time of the coolant in the heat dissipation cavity 51 can be effectively increased, thereby improving the heat dissipation efficiency.

[0044] Moreover, this staggered structure allows the coolant to form a complex flow path within the heat dissipation cavity 51, enhancing the heat exchange effect between the coolant and the wall of the heat dissipation cavity 51, and further improving the heat dissipation capacity of the kneading shell 11.

[0045] Specifically, a pump body 20 is provided on the top plate 13, the pump body 20 is connected to the inner cavity of the storage housing 30, and the connecting hose 21 is connected to the pump body 20.

[0046] In this embodiment, the pump body 20 facilitates the flow of coolant, allowing it to be introduced into the heat dissipation cavity 51 for heat dissipation.

[0047] Specifically, the two sets of storage housings 30 are matched with the two sets of guide rods 42, and the guide rods 42 are disposed in the inner cavity of the storage housing 30;

[0048] The outer wall of the guide rod 42 is provided with a toggle plate 60, which is slidably disposed in the inner cavity of the storage housing 30;

[0049] Multiple sets of actuation slots 61 are evenly provided on the actuation plate 60.

[0050] In this embodiment, during the lifting and lowering of the sealing cover 50, the guide rod 42 is lifted and lowered, thereby driving the actuating plate 60 to lift and lower within the storage housing 30. The sliding of the actuating plate 60 promotes the flow of coolant or other media within the storage housing 30, thereby enhancing the heat dissipation effect or achieving fluid control for other process requirements.

[0051] Specifically, the sealing cover 50 is provided with a sealing groove 54, which matches the top opening of the pinch housing 11;

[0052] The sealing cap 50 descends, so that the top opening of the pinch housing 11 is placed in the sealing groove 54.

[0053] In this embodiment, the sealing performance can be further improved by the sealing groove 54.

[0054] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
