Description

Technical Field

[0001] This utility model relates to the field of water-cooled connector technology, and in particular to an anti-condensation partition water-cooled connector. Background Technology

[0002] Vacuum slurry dipping tanks are primarily used in the preparation of surface shells in precision casting mold shell manufacturing processes. They improve slurry wettability, remove air bubbles, and can coordinate with robots to produce high-quality, stable mold shells. During operation, cooling water needs to be circulated through the vacuum slurry tank to prevent overheating. The slurry is placed inside the tank, which is a vacuum environment. Cooling water is introduced from outside the tank through a partition joint into a water-cooled stirring paddle inside.

[0003] The existing method of directly welding steel joints to the wall of the slurry tank causes the temperature of the tank wall near the joint to be close to the temperature of the cooling water, resulting in a large amount of condensate forming on the surface of the tank wall.

[0004] Therefore, it is necessary to develop a partition water-cooled connector that can maintain the vacuum environment inside the vacuum slurry tank and prevent condensation from appearing on the surface of the tank wall. Utility Model Content

[0005] Based on the above analysis, this utility model aims to provide an anti-condensation partition water-cooled joint to solve the problem that the existing steel joints are directly welded to the wall of the slurry tank, resulting in excessively low tank wall temperature near the joint and the condensation of a large amount of condensate on the tank wall surface.

[0006] The objective of this utility model is mainly achieved through the following technical solutions:

[0007] A condensation-resistant partition water-cooled connector includes: a partition connector, a sealing ring, a partition sleeve, and an inner connector; the partition sleeve is fixedly installed on the wall of a vacuum slurry tank; the partition connector is inserted into the partition sleeve; the partition connector has an internal threaded hole, and the inner connector passes through the partition sleeve and is threaded into the internal threaded hole; a limit stop is provided on the outer side of the partition connector, and the limit stop is sealed to the outer end face of the partition sleeve by a sealing ring; the partition connector and the inner connector are respectively used to connect the external cooling water pipe and the internal cooling water pipe of the tank.

[0008] Furthermore, the partition joint is made of a material with low thermal conductivity.

[0009] Furthermore, a stepped hole is formed inside the partition sleeve, the stepped hole including a first insertion hole and a second insertion hole; the insertion part of the partition connector is inserted into the first insertion hole of the partition sleeve; the inner connector passes through the second insertion hole and is threadedly connected to the partition connector.

[0010] Furthermore, the first socket and the outer wall of the plug-in portion are in a transition fit.

[0011] Furthermore, the inner connector is provided with a rotation limiting part. When the inner connector is tightened with the internal threaded hole, the rotation limiting part abuts against the inner end face of the partition sleeve, and the limiting stop abuts against the outer end face of the partition sleeve and simultaneously presses the sealing ring.

[0012] Furthermore, an annular groove is machined on the outer end face of the partition sleeve, and the annular groove is used to install the sealing ring.

[0013] Furthermore, the limiting stop is a regular square or regular hexagonal structure.

[0014] Furthermore, the axial length of the first socket is greater than the length of the insertion portion of the partition connector.

[0015] Furthermore, when the partition joint and the partition sleeve are inserted into place, the distance between the end face of the partition joint and the stepped surface of the stepped hole of the partition sleeve is 1mm to 2mm.

[0016] Furthermore, the partition sleeve is fixed to the wall of the vacuum dipping tank by welding, and the inner wall of the partition sleeve and the outer wall of the partition joint are transition fit; the partition joint and the inner joint are made of nylon.

[0017] The technical solution of this utility model can achieve at least one of the following effects:

[0018] 1. The anti-condensation partition water-cooled connector of this utility model is achieved by embedding a partition connector and an inner connector inside the partition sleeve, and connecting the external cooling water pipe and the internal cooling water pipe of the tank through the threaded connection of the partition connector and the inner connector. Furthermore, the partition connector is made of a material with a low thermal conductivity, so that when the cooling water flows in the partition connector and the inner connector, the low temperature of the cooling water will not be conducted or will be conducted only slightly to the partition sleeve and the cylinder wall of the vacuum slurry tank, so that the temperature of the cylinder wall of the vacuum slurry tank is higher than the condensation temperature, thus avoiding a large amount of condensation on the cylinder wall of the vacuum slurry tank.

[0019] 2. The anti-condensation partition water-cooled connector of this utility model, by setting a limiting stop on the outside of the partition connector and a rotating limiting part on the outside of the inner connector, ensures that when the partition connector and the inner connector are screwed into place, the limiting stop and the rotating limiting part abut against the outer end face and the inner end face of the partition sleeve, respectively. Furthermore, a sealing ring is set between the limiting stop and the partition sleeve to achieve vacuum sealing installation of the partition water-cooled connector on the vacuum slurry tank, which can maintain the vacuum environment inside the vacuum slurry tank.

[0020] In this invention, the above-described technical solutions can be combined with each other to achieve more preferred combinations. Other features and advantages of this invention will be set forth in the following description, and some advantages will become apparent from the description or be learned by practicing the invention. The objectives and other advantages of this invention can be realized and obtained from the description and accompanying drawings, which are particularly pointed out. Attached Figure Description

Detailed Implementation

[0029] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, which constitute a part of the present invention and are used together with the embodiments of the present invention to illustrate the principles of the present invention, but are not intended to limit the scope of the present invention.

[0030] Example 1

[0031] A specific embodiment of this utility model discloses an anti-condensation partition water-cooled connector, such as... Figure 1 , Figure 2As shown, it includes: a partition joint 2, a sealing ring 3, a partition sleeve 4, and an inner joint 6; the partition sleeve 4 is fixedly installed on the wall 5 of the vacuum slurry tank; the partition joint 2 is inserted into the partition sleeve 4; the partition joint 2 has an internal threaded hole 21 inside, and the inner joint 6 passes through the partition sleeve 4 and is screwed into the internal threaded hole 21; a limit stop 22 is provided on the outside of the partition joint 2, and the limit stop 22 is sealed to the outer end face of the partition sleeve 4 by the sealing ring 3; the partition joint 2 is made of a material with low thermal conductivity; the partition joint 2 and the inner joint 6 are respectively used to connect the external cooling water pipe 1 and the internal cooling water pipe 7, which can allow cooling water to flow from the outside of the vacuum slurry tank into the tank.

[0032] In this embodiment, the connection between the external cooling water pipe 1 and the internal cooling water pipe 7 is achieved by embedding the partition joint 2 and the inner joint 6 inside the partition sleeve and threading the partition joint 2 and the inner joint 6 together. By setting a sealing ring and setting the partition joint 2 to be made of a material with low thermal conductivity, the vacuum environment inside the vacuum slurry tank can be maintained when the cooling water flows through the partition joint 2 and the inner joint 6. At the same time, the low temperature of the cooling water will not be conducted or will be conducted only slightly to the partition sleeve 4 and the cylinder wall of the vacuum slurry tank, so that the temperature of the cylinder wall of the vacuum slurry tank is higher than the condensation temperature, thus avoiding the formation of condensate on the cylinder wall of the vacuum slurry tank.

[0033] Furthermore, in order to avoid or reduce condensation on the wall 5 of the vacuum slurry dipping tank, both the partition joint 2 and the inner joint 6 are made of nylon material with low thermal conductivity, which reduces heat transfer between the wall 5 of the vacuum slurry dipping tank and the anti-condensation partition water-cooled joint, and prevents the wall 5 of the vacuum slurry dipping tank from becoming too cold and condensing.

[0034] In this embodiment, as Figure 3 As shown, the partition connector 2 has an internal threaded hole 21 for threaded connection with the internal connector 6, and a limiting stop 22 is provided on the outside of the partition connector 2. The part of the partition connector from one end face of the limiting stop 22 to one end face of the partition connector 2 is the insertion part 23. When the partition connector 2 is inserted into the partition sleeve 4, the insertion part 23 is inserted into the inner wall surface of the partition sleeve 4, and the limiting stop 22 is attached to the outer end face of the partition sleeve 4.

[0035] In this embodiment, for ease of installation and clamping, the limiting stop 22 (the outer part of the partition connector 2) is machined into a regular square or a regular hexagon; in use, a wrench is used to clamp the limiting stop 22 of the partition connector 2, and then the inner connector 6 is rotated to achieve thread engagement between the two. Figure 2 As shown, the limiting stop 22 has a regular hexagonal structure.

[0036] In this embodiment, as Figure 4As shown, a stepped hole is formed inside the partition sleeve 4, the stepped hole including a first insertion hole 41 and a second insertion hole 42; and the diameter of the first insertion hole 41 is larger than the diameter of the second insertion hole 42.

[0037] Furthermore, the insertion part 23 of the partition connector 2 is inserted into the first insertion hole 41 of the partition sleeve 4; preferably, in order to ensure the overall rigidity of the water-cooled connector, the first insertion hole 41 and the outer wall of the insertion part 23 are in transition fit.

[0038] Furthermore, the inner connector 6 passes through the second insertion hole 42 and is threadedly connected to the partition connector 2. Preferably, the diameter of the inner connector 6 is smaller than the diameter of the second insertion hole 42, so that the inner connector 6 and the partition sleeve 4 do not come into contact, avoiding temperature transfer between the two, thereby ensuring that the temperature of the inner wall surface of the vacuum slurry tank 5 does not decrease.

[0039] In this embodiment, as Figure 5 As shown, the inner connector 6 is provided with an external thread 61 and a rotation limiting part 62 protruding from the external thread 61, and the diameter of the rotation limiting part 62 is larger than the diameter of the second insertion hole 42. Preferably, the rotation limiting part 62 is a regular polygonal structure, which facilitates the rotation of the inner connector 6 when it is screwed into the partition connector 2.

[0040] During implementation, since the inner connector 6 and the partition connector 2 are connected by a thread, as they gradually screw together, the distance between the rotation limiting part 62 on the outside of the inner connector 6 and the limiting stop part 22 on the outside of the partition connector 2 gradually decreases until they can no longer screw together. Figure 1 As shown, when the inner connector 6 is tightened with the inner threaded hole 21, the rotation limiting part 62 abuts against the inner end face of the partition sleeve 4, and the limiting stop part 22 abuts against the outer end face of the partition sleeve 4 and simultaneously presses against the sealing ring 3.

[0041] Furthermore, in order to ensure the vacuum sealing performance of the water-cooled joint, the sealing ring 3 is an O-ring; an annular groove 43 is machined on the outer end face of the partition sleeve 4, and the annular groove 43 is used to install the sealing ring 3.

[0042] Furthermore, the axial length of the first socket 41 is greater than the length of the insertion portion 23 of the partition connector 2.

[0043] Preferably, in order to ensure that the end face of the limiting stop 22 of the partition joint 2 is tightly fitted with the outer end face of the partition sleeve 4, when the partition joint 2 and the partition sleeve 4 are inserted into place, the distance between the end face of the partition joint 2 and the stepped surface of the stepped hole of the partition sleeve 4 is 1mm to 2mm.

[0044] Furthermore, the partition sleeve 4 is fixed to the wall 5 of the vacuum slurry dipping tank by welding. To facilitate connection with the external cooling water pipe 1, the internal threaded hole 21 on the inner wall of the partition joint 2 is a through hole.

[0045] See Figures 1-5 The installation method of the anti-condensation partition water-cooled joint of this utility model is as follows:

[0046] First, an appropriate opening is made in the wall 5 of the vacuum slurry tank. Then, the partition sleeve 4 is sealed and welded at the opening position in the wall 5 of the vacuum slurry tank. Next, the partition connector 2 is inserted into the partition sleeve 4 from outside the tank, and the inner connector 6 is screwed into the internal threaded hole 21 of the partition connector 2 inside the tank; until the end face of the partition connector 2 is tightly fitted with the end face of the partition sleeve 4, and the sealing ring 3 is fully compressed to achieve a vacuum seal.

[0047] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present utility model should be included within the protection scope of the present utility model.
