[0002] A salt mud pump is a key piece of equipment used for transporting brine to an electrolytic cell under high pressure. The mechanical seal pipe of the salt mud pump is a water pipe used to seal the mechanical seal device of the salt mud pump, and has functions such as cooling, lubrication and preventing leakage.

[0003] However, the existing mechanical seal water pipe of the salt mud pump, which is equipped with a circulating water pipe with an inner diameter of 7mm, is prone to scaling or blockage during the salt mud injection process. This results in poor or blocked circulating water flow in the mechanical seal of the salt mud pump, continuous increase in mechanical seal temperature, damage to the dynamic and static rings of the mechanical seal, and reduced working efficiency of the salt mud pump due to poor sealing. Furthermore, it is inconvenient to install and position the pump, and subsequent replacement operations are cumbersome. The sealing effect at the connection needs to be improved.

[0004] To address this issue, we propose a sealing pipe structure for a salt mud pump. Utility Model Content

[0005] The purpose of this utility model is to provide a structure for the mechanical seal water pipe of a salt mud pump, in order to solve the problems mentioned in the background art. The mechanical seal circulating water pipe of the salt mud pump has an inner diameter of 7mm. During the salt mud injection process, scaling or blockage of the circulating water pipe can easily occur, resulting in poor or blocked circulating water flow of the mechanical seal of the salt mud pump. The temperature of the mechanical seal will continue to rise, leading to damage to the dynamic and static rings of the mechanical seal. The working efficiency of the salt mud pump will decrease due to poor sealing. Moreover, it is inconvenient to install and position the pump, and the subsequent replacement operation is cumbersome. The sealing effect at the connection needs to be improved.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a mechanical seal water pipe structure for a salt mud pump, comprising a salt mud pump body, a mechanical seal pipe interface, and a mechanical seal pipe body that is connected to the mechanical seal pipe body;

[0007] Also includes:

[0008] The limiting mechanism is located at the lower end of the mechanical seal tube body, and the limiting mechanism drives the mechanical seal tube body and the mechanical seal tube interface to form a disassembly structure. The limiting mechanism consists of a limiting sleeve sleeved at the lower end of the mechanical seal tube body, a fixing rod fixed at the front and rear ends of the limiting sleeve, a protrusion for positioning, a support plate fixed at the upper right end of the salt mud pump body, and a fixing groove opened in the support plate.

[0009] The upper end of the fixed rod is fitted with a movable pressure plate for pressing and limiting.

[0010] Preferably, the inner diameter of the mechanical seal tube body is 13mm.

[0011] Preferably, the lower end of the mechanical seal tube body is inserted into the mechanical seal tube interface, and a first sealing ring is provided between the mechanical seal tube body and the mechanical seal tube interface.

[0012] Preferably, the limiting sleeve is fitted onto the outer surface of the mechanical seal tube interface, and the limiting sleeve presses the mechanical seal tube body tightly onto the mechanical seal tube interface. At the same time, a second sealing ring is provided between the lower end of the limiting sleeve and the mechanical seal tube interface.

[0013] Preferably, the limiting sleeve drives the fixing rod to engage in the support plate, and the upper end of the fixing rod is fixedly connected to a protrusion, which engages in the connecting groove opened on the upper end of the movable pressure plate.

[0014] Preferably, a connecting rod is inserted into the lower end of the movable pressure plate, and the connecting rod is fixedly connected to the side of the support plate, and the movable pressure plate is sleeved on the outside of the support plate.

[0015] Preferably, the outer surface of the connecting rod is threaded with a fixing cap for locking and limiting, and the fixing cap is fitted to the side of the movable pressure plate.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows: The mechanical seal water pipe structure of this salt mud pump expands the inner diameter of the mechanical seal pipe body to 13mm, reducing the probability of scaling or clogging of the circulating water pipe, greatly reducing the probability of poor flow or blockage of the mechanical seal circulating water, ensuring the efficiency of salt mud injection while reducing material consumption costs, and changing the parts provided by the manufacturer to self-made parts, thus reducing procurement costs. The setting of the first sealing ring and the second sealing ring can achieve a good sealing effect at the joint between the mechanical seal pipe interface and the mechanical seal pipe body. Combined with the setting of the limiting mechanism and the movable pressure plate, the limiting sleeve and the mechanical seal pipe interface can be limited very stably and conveniently, making it easy to disassemble and replace the mechanical seal pipe body.

[0017] 1. It is equipped with a mechanical seal pipe interface and a mechanical seal pipe body. The lower end of the mechanical seal pipe body is inserted into the mechanical seal pipe interface, which expands the inner diameter of the traditional mechanical seal pipe body from 7mm to 13mm, reducing the probability of poor flow or blockage of mechanical seal circulating water.

[0018] 2. It is provided with a first sealing ring, a limiting sleeve and a second sealing ring. The first sealing ring is fitted between the mechanical seal tube body and the mechanical seal tube interface, and the second sealing ring is fitted between the limiting sleeve and the mechanical seal tube interface, which can effectively ensure the sealing effect of the connection and prevent leakage.

Detailed Implementation

[0027] 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.

[0028] Please see Figures 1-6 .

[0029] To address the existing problems in the mechanical seal water pipe of a salt mud pump, where the inner diameter of the circulating water pipe is 7mm and it is prone to scaling or blockage during salt mud injection, resulting in poor or blocked circulating water flow, continuously rising mechanical seal temperature, damage to the dynamic and static rings, reduced pump efficiency due to poor sealing, inconvenient installation and positioning, cumbersome replacement operations, and inadequate sealing at the connection points, this solution proposes a salt mud pump mechanical seal water pipe structure. This structure includes a salt mud pump body 1, a mechanical seal pipe interface 3, and a mechanical seal pipe body 4 that connects to the mechanical seal pipe body 4. A limiting mechanism 6 is located at the lower end of the mechanical seal pipe body 4, and the limiting mechanism 6 enables a disassembly structure between the mechanical seal pipe body 4 and the mechanical seal pipe interface 3.

[0030] like Figure 1 and Figure 2 As shown, a fixing plate 2 is fixed at the lower end of the salt mud pump body 1, and an organic seal pipe interface 3 is provided at the upper right end of the salt mud pump body 1. The inner diameter of the organic seal pipe body 4 is expanded from the traditional 7mm to 13mm. In actual use, due to the increased inner diameter, the probability of scaling or clogging of the circulating water pipe is reduced, which reduces the probability of poor flow or blockage. Moreover, the parts provided by the manufacturer are replaced by self-made parts, which reduces the procurement cost while ensuring the efficiency of salt mud injection and reducing material consumption costs.

[0031] When installing the mechanical seal pipe body 4 and the mechanical seal pipe interface 3, a limiting mechanism 6 is used. This limiting mechanism consists of a limiting sleeve 7 fitted onto the lower end of the mechanical seal pipe body 4, fixing rods 8 fixed to the front and rear ends of the limiting sleeve 7, a positioning protrusion 9, a support plate 10 fixed to the upper right end of the salt mud pump body 1, and a fixing groove 11 formed in the support plate 10. A movable pressure plate 13 for pressing and limiting is fitted abutting the upper end of the fixing rod 8. Figure 3 , Figure 4 , Figure 5 and Figure 6As shown, the limiting sleeve 7 is fitted onto the lower end of the mechanical seal tube body 4. The limiting sleeve 7 drives the mechanical seal tube body 4 to be inserted into the mechanical seal tube interface 3. A first sealing ring 5 is fitted between the mechanical seal tube body 4 and the mechanical seal tube interface 3. The limiting sleeve 7 is fitted onto the outside of the mechanical seal tube interface 3, and a second sealing ring 16 is fitted between the lower end of the limiting sleeve 7 and the mechanical seal tube interface 3 to ensure the sealing effect at the connection. The limiting sleeve 7 drives the fixing rod 8 to engage in the fixing groove 11. Then, the movable pressure plate 13 is moved. The movable pressure plate 13 slides between itself and the connecting rod 12, and the movable pressure plate 13 moves to the outside of the support plate 10. The movable pressure plate 13 is moved so that it fits against the upper end of the fixed rod 8, and the protrusion 9 engages in the connecting groove 14 at the upper end of the movable pressure plate 13. Then, the fixing cap 15, which is threaded to the outer surface of the connecting rod 12, is rotated. The fixing cap 15 fits against the side of the movable pressure plate 13, which facilitates the limiting of the fixed rod 8 and the support plate 10, and fixes the limiting sleeve 7. The limiting sleeve 7 is used to press and fix the mechanical seal tube body 4, which facilitates the stable limiting of the mechanical seal tube body 4 and the mechanical seal tube interface 3. Moreover, the mechanical seal tube body 4 can be disassembled and replaced by reversing the above operation.

[0032] 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.
