Description

Technical Field

[0001] This utility model relates to the field of pigment reaction vessel technology, and more specifically, to a pigment reaction vessel. Background Technology

[0002] A reaction vessel is a piece of equipment used in the production of pigments. It is a container for the reaction of raw materials. The reaction vessel includes a vessel body with a discharge port at the bottom. A sealing cover that closes the discharge port is hinged to the vessel body. Since the chemical reaction of pigments is sensitive to pH value, a pH testing device is usually installed in the reaction vessel to facilitate operators to monitor the pH value of the raw materials in real time.

[0003] The pH testing device includes a test head and a control box. The test head is used to directly contact the raw materials, while the control box is responsible for converting the signal read by the test head into a signal that can be read by the operator. Most existing pH testing devices are fixedly installed at the bottom of the reaction vessel. Some oily pigments tend to adhere to the test head, affecting the accuracy of the test head. Therefore, the test head needs to be cleaned after each pigment production. However, since the test head is located relatively deep inside the vessel, the operator usually needs to use tools such as a lamp or water gun to reach into the vessel to clean the test head, which makes cleaning inconvenient.

[0004] Therefore, a new solution is needed to address this problem. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a pigment reaction vessel.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a pigment reaction vessel, including a vessel body, a discharge port at the bottom of the vessel body, a sealing cover hinged to the vessel body for sealing the discharge port, a groove on the side wall of the sealing cover facing the vessel body, a control box detachably connected to the side wall of the sealing cover facing away from the vessel body, a stepped hole on the bottom wall of the groove, a test head fixed on the control box passing through the stepped hole, the end of the test head being completely embedded in the groove, a sealing ring abutting against the inner wall of the stepped hole on the outer peripheral wall of the test head, and a groove communicating with the stepped hole on the side wall of the groove.

[0007] The present invention is further configured such that: the stepped hole includes a countersunk hole and a round hole that are interconnected and coaxially arranged, the round hole is connected to the side wall of the sealing cover, the diameter of the countersunk hole is larger than the diameter of the round hole, and the longitudinal section of the sealing ring is T-shaped.

[0008] The present invention is further configured such that: an annular wall is fixed on the bottom wall of the countersunk hole along the edge of the circular hole, and an annular groove for embedding the annular wall is provided on the sealing ring.

[0009] The present invention is further configured such that the thickness at the connection between the ring wall and the bottom wall of the countersunk hole is less than the thickness of the ring wall at a location away from the bottom wall of the countersunk hole.

[0010] The present invention is further configured such that: the ring wall and the sealing cap are integrally formed, and a knife groove is provided on the top surface of the ring wall.

[0011] The present invention is further configured such that the inner peripheral walls of the countersunk hole and the round hole are both sandblasted.

[0012] In summary, this utility model has the following beneficial effects: After pigment processing is completed in the pigment reactor, the sealed cover is opened to drain the pigment from the reactor, fully exposing the test head to the operator. Once the pigment is drained, the operator can directly clean the test head. Compared to existing methods of cleaning test heads, this setup makes cleaning much more convenient and allows the operator to easily observe whether there is any pigment residue on the test head surface. This effectively avoids the impact of pigment residue on the accuracy of subsequent pigment production pH tests. Simultaneously, the operator needs to clean the grooves to prevent pigment residue from remaining. When the test head or control box malfunctions and requires repair, the control box can be removed from the sealed cover for cleaning. The box is inspected or replaced. During the operation of the reactor, the sealing ring set in the step hole can prevent the pigment in the reactor body from leaking out of the step hole. Specifically, the sealing ring is made of fluororubber material. Fluororubber has excellent chemical resistance. The sealing ring made of this material can adapt to the working environment of long-term contact with pigment, ensuring the sealing effect of the sealing ring on the sealing cover and the test head. The end of the test head is completely embedded in the groove. During the operation of the reactor, the pigment may form turbulence in the reactor body. The setting of completely embedding the test head in the groove can reduce the impact of pigment turbulence on the test head, reduce the possibility of damage to the test head caused by the impact of pigment turbulence, and improve the service life of the test head.

[0015] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0016] A pigment reaction vessel, such as Figure 1 and Figure 2 As shown, the device includes a vessel body 1, with a discharge port 2 at the bottom. A sealing cover 3 for sealing the discharge port 2 is hinged to the vessel body 1. A groove 4 is provided on the side wall of the sealing cover 3 facing the vessel body 1. A control box 5 is detachably connected to the side wall of the sealing cover 3 facing away from the vessel body 1 by screws. A stepped hole is provided on the bottom wall of the groove 4. A test head 6 passing through the stepped hole is fixed on the control box 5. A sealing ring 7 is detachably connected to the outer peripheral wall of the test head 6 and abuts against the inner peripheral wall of the stepped hole. The inner peripheral wall of the sealing ring 7 abuts against the outer peripheral wall of the test head 6. A slot 13 communicating with the stepped hole is provided on the side wall of the groove 4. There are two slots 13, symmetrically arranged around the center of the stepped hole. After the pigment processing is completed in the pigment reactor, the operator opens the sealing cover 3 along its hinged position to discharge the pigment from the reactor body 1. At this time, the test head 6 set on the sealing cover 3 is fully exposed to the operator. After the pigment is discharged, the operator can directly clean the test head 6. Compared with the existing cleaning method of the test head 6, the above arrangement makes the cleaning of the test head 6 very convenient, and also makes it easier for the operator to observe whether there is pigment residue on the surface of the test head 6, which can effectively avoid the test head... 6. The impact of pigment residue on the accuracy of pH value testing in subsequent pigment production. Simultaneously, operators need to clean groove 4 to prevent pigment residue from remaining in groove 4. When the test head 6 or control box 5 malfunctions and requires repair, the sealing ring 7 is removed from the stepped hole by inserting it into the slot 13. The slot 13 provides a good position for applying force to remove the sealing ring 7. The control box 5 is removed from the sealing cover 3 for inspection or replacement. During reactor operation, the sealing ring 7 in the stepped hole prevents pigment in the reactor body 1 from leaking out through the stepped hole. The leakage is specifically addressed by the fact that the sealing ring 7 is made of fluororubber, which has excellent chemical resistance. The sealing ring 7 made of this material can adapt to working environments where it is in contact with pigments for a long time, ensuring the sealing effect of the sealing ring 7 on the sealing cover 3 and the test head 6. The end of the test head 6 is completely embedded in the groove 4. During the operation of the reactor, the pigment may form turbulence in the reactor body 1. The setting of completely embedding the test head 6 in the groove 4 can reduce the impact of pigment turbulence on the test head 6, reduce the possibility of damage to the test head 6 caused by the impact of pigment turbulence, and improve the service life of the test head 6.

[0017] like Figure 2As shown, the stepped hole includes a countersunk hole 8 and a circular hole 9 that are interconnected and coaxially arranged. The aforementioned groove 13 communicates only with the countersunk hole 8, and the circular hole 9 communicates with the side wall of the sealing cap 3 away from the vessel body 1. The diameter of the countersunk hole 8 is larger than the diameter of the circular hole 9. The longitudinal section of the sealing ring 7 is T-shaped. This arrangement allows the bottom wall of the countersunk hole 8 to provide a supporting force for the sealing ring 7 when it is subjected to pigment pressure. This keeps the sealing ring 7 in a balanced state under the pressure of the pigment and the supporting force of the bottom wall of the countersunk hole 8, preventing the sealing ring 7 from being forced open by the pigment pressure. This ensures the sealing effect of the sealing ring 7 on the sealing cap 3 and the test head 6. A ring is fixed on the bottom wall of the countersunk hole 8 along the edge of the circular hole 9. Along the provided annular wall 10, which is integrally formed on the bottom wall of the countersunk hole 8, the sealing ring 7 has an annular groove 11 for embedding the annular wall 10. When using the sealing ring 7, the annular wall 10 needs to be embedded in the annular groove 11. This arrangement allows the annular wall 10 to provide good radial support for the sealing ring 7, enabling the outer peripheral wall of the sealing ring 7 to abut against the inner peripheral wall of the countersunk hole 8. This reduces the possibility of gaps forming between the sealing ring 7 and the inner peripheral wall of the countersunk hole 8 under pigment pressure, improving the sealing performance between the sealing ring 7 and the inner peripheral wall of the countersunk hole 8. At the same time, the annular wall 10 will abut against the side wall of the annular groove 11, allowing the annular wall 10 to also provide a seal. Ring 7 provides support, further reducing the amount of deformation of sealing ring 7 under pigment pressure, ensuring the sealing performance between sealing ring 7 and the inner peripheral wall of counterbore 8. The thickness of the connection between ring wall 10 and the bottom wall of counterbore 8 is less than the thickness of ring wall 10 away from the bottom wall of counterbore 8. When not in use, the width of the annular groove 11 of sealing ring 7 is equal to the width of the thinnest part of ring wall 10. After the operator fully installs sealing ring 7 into the stepped hole, the thicker end of ring wall 10 will abut against the outer peripheral wall of annular groove 11 and cause sealing ring 7 to press tightly against the inner peripheral wall of counterbore 8, improving the sealing performance between sealing ring 7 and the inner peripheral wall of counterbore 8. At the same time, this setting... This also makes it difficult for the sealing ring 7 to detach from the countersunk hole 8 on its own. The ring wall 10 and the sealing cover 3 are integrally formed. A cutting groove 12 is provided on the top surface of the ring wall 10. During the process of forming the ring wall 10 using a milling cutter, the cutting groove 12 facilitates the milling cutter to process the outer peripheral wall of the ring wall 10. The inner peripheral walls of the countersunk hole 8 and the round hole 9 are both sandblasted. The surface roughness of the inner peripheral walls of the countersunk hole 8 and the round hole 9 after sandblasting is significantly improved, which can increase the friction when the outer peripheral wall of the sealing ring 7 comes into contact with the inner peripheral walls of the countersunk hole 8 and the round hole 9, ensuring the stability of the sealing ring 7 installed in the stepped hole, so that the sealing ring 7 can better adapt to the high-pressure working environment of the vessel body 1.

All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
