[0022] In view of this, the core of the present invention is to provide a hydraulic plug-in mechanism, improve the sealing performance of the hydraulic plug-in mechanism, and extend the service life of the hydraulic plug-in mechanism.

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] like Figures 1 to 3 As shown, an embodiment of the utility model discloses a dosing device for a belt filter press, which is characterized by comprising a sludge pipe 20 and a sleeve 10.

[0025] Among them, the sludge pipe 20, the first connecting piece 50 and the second connecting piece 60 are respectively arranged at both ends of the sludge pipe 20, the first connecting piece 50 and the second connecting piece 60 are respectively connected to the sludge inlet pipe of the belt filter press, and the sludge pipe 20 is provided with a plurality of dosing holes 21; the sleeve 10 is sleeved on the outside of the sludge pipe 20, and a dosing space is formed between the sleeve 10 and the sludge pipe 20, and the sleeve is provided with a dosing port 30.

[0026] The above-mentioned medicine adding space can be of annular or square type, and as long as it is a space that allows the medicine to circulate in the medicine adding space, it belongs to the protection scope of the utility model; optionally, the medicine adding space provided by the utility model is an annular space.

[0027] In addition, the above-mentioned first connecting member and the second connecting member can both be connecting members of the type of flanges, clamps or connecting plates. As long as the type of connecting member can meet the use requirements, it belongs to the protection scope of the present utility model; optionally, the first connecting member and the second connecting member provided by the present utility model are the first flange and the second flange respectively.

[0028] The beneficial effects of the belt filter press dosing device provided by the utility model are as follows:

[0029] When the agent enters the agent adding space formed by the sleeve 10 and the sludge pipe 20 through the agent adding port 30, it enters the interior of the sludge pipe through the multiple agent adding holes 21 arranged on the sludge pipe 20, and is fully mixed with the sludge flowing in the sludge pipe 20. It can be seen that the agent adding device for the belt filter press provided by the utility model is convenient and quick to operate in practical applications, and can effectively improve the mixing efficiency of the agent and the sludge.

[0030] like Figure 3 As shown, the plurality of dosing holes 21 are evenly distributed along the circumferential direction of the sludge pipe 20, so that the agent can be evenly distributed in the sludge pipe, increase the contact area with the sludge, and be fully mixed with the sludge inside the sludge pipe.

[0031] The above-mentioned dosing hole 21 can be of circular or square type, and as long as it is a hole that can allow the agent to enter the sludge pipe, it belongs to the protection scope of the present utility model; optionally, the dosing hole provided by the present utility model is a circular hole.

[0032] Furthermore, the dosing port 30 is provided with a first flow detection element and a valve, and the belt filter press dosing device also includes a second flow detection element for detecting the sludge conveying flow rate, and the first flow detection element and the valve and the second flow detection element are all connected to the central controller signal, so that when the second flow detection element detects an increase in the sludge flow rate, the central controller controls the valve opening to increase, so that the flow rate of the agent increases, and when the first flow detection element detects that the flow rate of the agent reaches a preset flow value, the central controller controls the valve opening to maintain, so that the agent flow rate is adapted to the sludge conveying flow rate, so that the agent can be mixed with the sludge more evenly, and the degree of automation of the device is also enhanced.

[0033] Furthermore, the first connecting member 50 is a first flange, and the second connecting member 60 is a second flange. The first flange and the second flange are respectively welded to the two ends of the sludge pipe. On the one hand, based on the welding form, the connection strength between the flange and the sludge pipe is enhanced, ensuring the safety and reliability of the structure; on the other hand, the sludge pipe is connected by the flange, the structure is simple, and it is easy to assemble.

[0034] In addition, a third connecting member 40 is also included, and the third connecting member 40 is connected to the drug adding port 30, so that the connection structure is simple and easy to assemble.

[0035] Furthermore, the third connecting member 40 is a third flange, and the third flange is welded to the dosing port 30. The welding form enhances the connection strength between the flange and the dosing port, thereby ensuring the safety and reliability of the structure.

[0036] Furthermore, the diameter of the dosing port 30 is not less than the diameter of the dosing pipe of the belt filter press, ensuring that the agent is not obstructed in the pipeline and can flow quickly.

[0037] Furthermore, the size and number of the dosing holes 21 are related to the dosing amount, and are not specifically limited. The present solution proposes an embodiment in which the size of the dosing holes 21 is 5-10 mm, and the number of the dosing holes 21 is 4-16.

[0038] Furthermore, the sludge pipe 20 and the casing 10 are both made of carbon steel or stainless steel, which has the advantages of corrosion resistance and long service life.

[0039] The working principle of the belt filter press dosing device provided by the utility model is as follows:

[0040] When the agent in the dosing pipe of the belt filter press is controlled by the central controller to control the valve opening, the agent enters the annular dosing space formed by the casing 10 and the sludge pipe 20 through the dosing port 40. The dosing space is used to circulate the agent. The agent passes through a plurality of dosing holes 21 evenly arranged along the circumferential direction on the sludge pipe 20 to the inside of the sludge pipe 20, thereby being evenly distributed in the sludge pipe 20 to increase the contact area with the sludge. At this time, the sludge passes through the inlet end of the mud inlet pipe of the belt filter press to the inside of the sludge pipe 20. At the same time, the central controller controls the first flow detection element to detect the amount of the agent entering the dosing space. The second flow detection element detects the conveying flow of the sludge entering the sludge pipe. When the central controller controls the valve opening to increase, the flow of the agent detected by the first flow detection element also increases. Then the central controller controls the second flow detection element to detect the conveying flow of the sludge. When the first flow detection element detects that the flow of the agent reaches the preset flow value, the central controller controls the valve opening to maintain the flow of the agent to match the sludge conveying flow. Then, the agent and the sludge are fully mixed inside the sludge pipe 20, thereby improving the mixing efficiency of the agent and the sludge and enhancing the degree of automation of the device.
