TECHNICAL FIELD

[0001] The utility model relates to water treatment technical field, especially to a dosing head of hard water catalytic softening equipment. BACKGROUND

[0002] Hard water as the cooling water of industrial production can make the heat exchanger scale, and seriously hinder the water flow passage, greatly reduce the heat exchange effect, affect the smooth production, even forced to stop production, and reducing the hardness of industrial water not only is favorable to the normal operation of equipment, but also can improve the utilization rate of water.

[0003] At present, there are many industrial water softening technologies, and the catalytic softening equipment has the advantages of small equipment occupation, low investment cost, good treatment effect, no waste water and harmful waste, and is widely used in industrial water softening, such as the hard water softening tank based on parent body multiplication disclosed in the existing patent announcement No.

[0004] Since the hard water softening tank needs to continuously add reaction reagent during operation, and the second buffer cap and the third buffer cap are used as the dosing head, and the drain port is directly arranged on the second buffer cap and the third buffer cap, the crystal seed is easy to be blocked and the liquid backflow occurs, causing the dosing head to be blocked.

[0005] In summary, the above-mentioned existing dosing head is easy to be blocked due to liquid backflow. UTILITY MODEL CONTENT

[0006] The utility model provides a dosing head of hard water catalytic softening equipment, aims at solving the technical problem that the dosing head of existing hard water catalytic softening equipment is easy to be blocked due to liquid backflow.

[0007] In order to solve the above technical problem, the utility model adopts the following technical scheme:

[0008] A dosing head of hard water catalytic softening equipment, comprising a nozzle cap and a nozzle, the first end of the nozzle cap is connected and fixed with the nozzle, the second end of the nozzle cap is used for being connected with a liquid inlet pipe, the nozzle is an elastic conical table, the conical table seals the port of the first end of the nozzle cap, the conical surface of the conical table is elastically deformed under the liquid extrusion force in the nozzle cap, forcing the conical surface of the conical table and the inner wall of the port of the first end of the nozzle cap to generate a liquid gap.

[0009] Further, the port of the first end of the nozzle cap is a conical port matched and sealed with the taper of the conical table.

[0010] Furthermore, the inner cavity of the nozzle cap includes a first inner cavity and a second inner cavity that are interconnected. The first inner cavity is in communication with the conical orifice and is located between the conical orifice and the second inner cavity. The second inner cavity is used to connect with the liquid inlet pipe. The inner diameter of the first inner cavity is smaller than the inner diameter of the second inner cavity.

[0011] Furthermore, the end of the conical platform facing away from the conical opening is located within the first inner cavity, and the diameter of the end of the conical platform facing away from the conical opening is smaller than the diameter of the end of the conical platform closer to the conical opening.

[0012] Furthermore, a fixing seat is fixed inside the nozzle cap, the fixing seat is located between the nozzle and the liquid inlet pipe, and a liquid inlet channel is provided between the fixing seat and the inner wall of the nozzle cap, and the conical platform is fixed on the fixing seat.

[0013] Furthermore, the conical platform is fixed to the fixed base by bolts.

[0014] Furthermore, the fixed base has a threaded hole that extends through the fixed base along the axial direction of the nozzle cap. The cone has a through hole at its center. The bolt extends through the through hole from one end of the cone along the axial direction of the nozzle cap and is threadedly connected to the threaded hole. The bolt is also sealed with a first sealing gasket between the cone and the fixed base and a second sealing gasket between the cone and the end of the bolt.

[0015] Furthermore, the inner wall of the nozzle cap is provided with an annular mounting groove for mounting the fixing seat in the circumferential direction.

[0016] Furthermore, the annular mounting groove is detachably connected to the fixing base.

[0017] Furthermore, the inner or outer wall of the second end of the nozzle cap is provided with a thread for connection to the liquid inlet pipe.

[0018] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0019] The dosing head of this invention designs the nozzle as an elastic conical platform. During the dosing process, after the liquid medicine enters the nozzle cap through the inlet pipe, the pressure of the liquid medicine will squeeze the conical surface of the platform to undergo elastic deformation, forcing a liquid outlet gap to be created between the conical surface of the platform and the inner wall of the first end of the nozzle cap. In this way, the liquid medicine will spray out from the liquid outlet gap. When the dosing stops, the liquid medicine pressure decreases, and the conical platform recovers its deformation under its own elastic force, so that the conical platform returns to the state of closing the first end of the nozzle cap. In this way, external water flow and seed crystals cannot flow back into the nozzle cap through the nozzle, thereby avoiding the seed crystals and water flow flowing back into the nozzle cap and reacting with the liquid medicine inside the nozzle cap, which would cause blockage of the dosing head.

[0034] Please refer to Figure 1 - Figure 8 The utility model provides a kind of dosing head of hard water catalytic softening equipment, including nozzle cap 1 and nozzle 2, the first end of nozzle cap 1 is connected with nozzle 2 and is fixed, the second end of nozzle cap 1 is used to connect with inlet tube 4, nozzle 2 is elastic conical table, that is, conical table is made of elastic material.

[0035] Refer to Figure 3 And Figure 6 Conical table closes the port of the first end of nozzle cap 1, specifically can be understood, the first end of conical table is inserted into nozzle cap 1, the second end of conical table closes the port of the first end of nozzle cap 1, so that the liquid medicine in nozzle cap 1 can be contacted with the conical surface of conical table. In the process of dosing, after liquid medicine enters nozzle cap 1 by inlet tube 4, the pressure of liquid medicine will extrude the conical surface of conical table and be elastically deformed, force the conical surface of conical table and the inner wall between the port of the first end of nozzle cap 1 produce liquid gap, so liquid medicine will be sprayed from liquid gap;When stopping dosing, liquid pressure decreases, conical table restores deformation under the action of its own elasticity, so that conical table restores to the state of closing the port of the first end of nozzle cap 1, so that external water flow and seed cannot flow back into nozzle cap 1 through nozzle 2, to avoid that seed and water flow back into nozzle cap 1 and react with liquid medicine in nozzle cap 1 to cause dosing head to be blocked.

[0036] Refer to Figure 3The port of the first end of the nozzle cap is a tapered port 12 which is sealed by matching the taper of the conical surface of the conical platform, so that the sealing performance between the nozzle 2 and the nozzle cap 1 can be improved.

[0037] With reference to Figure 3 and Figure 4 , the inner cavity of the nozzle cap 1 includes a first inner cavity 3 and a second inner cavity 31 which are in communication with each other. The first end inner cavity of the nozzle cap 1 is the first inner cavity 3, and the second end inner cavity of the nozzle cap 1 is the second inner cavity 31. The first inner cavity 3 penetrates the tapered port 12, and is located between the tapered port 12 and the second inner cavity 31. The second inner cavity 31 is used to connect with the liquid inlet pipe 4. The inner diameter of the first inner cavity 3 is smaller than that of the second inner cavity 31. Therefore, it can be understood that after the liquid medicine enters the second inner cavity 31 through the liquid inlet pipe 4, it enters the first inner cavity 3. Since the inner diameter of the first inner cavity 3 is smaller than that of the second inner cavity 31, the liquid medicine can be pressurized, and the thrust of the liquid medicine can push the nozzle 2 away. In addition, the end of the conical platform away from the tapered port is located in the first inner cavity 3, and the diameter of the end of the conical platform away from the tapered port 12 is smaller than that of the end of the conical platform close to the tapered port 12. Therefore, the liquid medicine entering the first inner cavity 3 from the second inner cavity 31 can further open the nozzle 2.

In this way, the fixed seat 6 can avoid blocking the liquid medicine from entering the nozzle 2 from the liquid inlet pipe 4.

[0039] In an embodiment, with reference to Figure 4 , Figure 6 , Figure 7 and Figure 8 , the conical platform is fixed on the fixed seat 6 by a bolt 5. Specifically, a threaded hole 60 is formed on the fixed seat 6, the threaded hole 60 penetrates the fixed seat 6 along the axial direction of the nozzle cap 1, a through hole 20 is formed in the center of the conical platform, the bolt 5 penetrates the through hole 20 from one end of the conical platform along the axial direction of the nozzle cap 1 and is threadedly connected with the threaded hole 60, and the bolt 5 is sealingly connected with a first sealing gasket 50 located between the conical platform and the fixed seat 6 and a second sealing gasket 51 located between the conical platform and the end of the bolt 5. The first sealing gasket 50 and the second sealing gasket 51 are mainly used to block the liquid from entering the nozzle cap 1 from the through hole 20 on the conical platform. Of course, in other embodiments, the conical platform can also be fixed on the inner wall of the nozzle cap 1 by a cantilever, which is not limited here.

[0040] In an embodiment, with reference to Figure 3 , Figure 6 andFigure 8 The inner wall of the nozzle cap 1 is circumferentially provided with an annular mounting groove 11 for mounting the fixing seat 6, and the fixing seat 6 can be conveniently mounted through the annular mounting groove 11. Specifically, one end of the fixing seat 6 is located in the annular mounting groove 11, and the other end of the fixing seat 6 is located in the first inner cavity 3; the annular mounting groove 11 is detachably connected with the fixing seat 6, so that the fixing seat 6 can be conveniently detached from the nozzle cap 1. The fixing seat 6 can be fixed on the annular mounting groove 11 by screws.
