Description

Technical Field

[0001] The utility model relates to the technical field of pressure tanks, in particular to a pressure grouting tank. Background Art

[0002] Currently, in pharmaceutical and food production, it is usually necessary to add water to the powder, heat it, and mix it, so as to complete the slurry preparation operation with a relatively high viscosity. After the slurry preparation is completed, the slurry is added to the slurry tank, and then transported and cooled through the slurry tank.

[0003] The adhesive is poured into the tank manually, and the pressure must be released before opening the lid. The lid needs to be tightened with auxiliary tools when installed, which may cause secondary pollution and air leakage that affect the slurry addition. The mouth of the 30-liter slurry adding tank is 1 meter from the ground, and the mouth of the 100-liter pressure slurry adding tank is 1.3 meters from the ground. It is inconvenient to add slurry and there is a risk of spillage. Utility Model Content

[0004] The purpose of the utility model is to provide a pressure grouting tank in order to overcome the shortcomings and deficiencies of the prior art.

[0005] The technical solution adopted by the utility model is as follows: a pressure grouting tank, comprising a tank body and a slurry outlet located at the bottom of the tank body, the tank body having a slurry inlet and an air port, and also comprising a three-way ball valve A and a three-way ball valve B,

[0006] The three flow channels of the three-way ball valve A are respectively connected to the vacuum generating device, the positive pressure device and the air port; the three flow channels of the three-way ball valve B are respectively connected to the pulp inlet, the pulp inlet channel and the safety valve.

The valve core of the three-way ball valve B rotates to have a first slurry suction position connected to the slurry inlet and the slurry inlet channel, and a first slurry discharge position connected to the slurry inlet and the safety valve.

[0008] When the valve core of the three-way ball valve A is located at the first negative pressure position, the valve core of the three-way ball valve B is located at the first slurry suction position, and the slurry outlet is in a closed state; when the valve core of the three-way ball valve A is located at the first positive pressure position, the valve core of the three-way ball valve B is located at the first slurry discharge position, and the slurry outlet is in a closed state or an open state.

[0011] Preferably, the outer wall of the tank body is fixedly connected with a plurality of mounting seats, the bottoms of the mounting seats are fixedly connected with a plurality of support rods, and the bottoms of the support rods are fixedly connected with moving wheels.

[0012] Preferably, a window is provided on one side of the tank body.

[0013] Preferably, a flip-up slurry adding port is provided on the top of the tank body.

[0014] Preferably, the three-way ball valve A is connected to the air port clamp.

[0015] Preferably, the three-way ball valve B is connected to the slurry inlet clamp.

This structure does not change the structure and configuration of the tank body; only two three-way valves need to be added to achieve negative pressure slurry suction and positive pressure slurry discharge. This structure greatly improves the efficiency of slurry addition, reduces the labor intensity of workshop operators, and reduces the risk of secondary contamination of the slurry.

[0022] In order to make the purpose, technical solutions and advantages of the present invention more clear, the present invention will be described in further detail below with reference to the accompanying drawings.

[0023] It should be noted that all expressions using "first" and "second" in the embodiments of the present invention are for the purpose of distinguishing two non-identical entities or non-identical parameters with the same name. It can be seen that "first" and "second" are only for the convenience of expression and should not be understood as limitations on the embodiments of the present invention. Subsequent embodiments will not explain this one by one.

[0024] The directional and positional terms used in this invention, such as "upper," "lower," "front," "back," "left," "right," "inner," "outer," "top," "bottom," and "side," are used solely to refer to the directions or positions in the accompanying drawings. Therefore, the directional and positional terms used are intended to illustrate and facilitate understanding of this invention and are not intended to limit the scope of protection of this invention.

[0025] like Figures 1 to 3 As shown in the figure, a pressure grouting tank in an embodiment of the present invention comprises a tank body 1 and a slurry outlet 13 at the bottom of the tank body 1. The tank body 1 has a slurry inlet 11 and an air outlet 12, and further comprises a three-way ball valve A and a three-way ball valve B.

[0026] The three flow channels of the three-way ball valve A are respectively connected to the vacuum generating device, the positive pressure device, and the air port 12; the three flow channels of the three-way ball valve B are respectively connected to the pulp inlet 11, the pulp inlet channel, and the safety valve.

[0027] The valve core of the three-way ball valve A rotates to have a first negative pressure position connected to the vacuum generating device and the air port 12, and a first positive pressure position connected to the positive pressure device and the air port 12. The valve core of the three-way ball valve B rotates to have a first slurry suction position connected to the slurry inlet 11 and the slurry inlet channel, and a first slurry discharge position connected to the slurry inlet 11 and the safety valve.

[0028] When the valve core of the three-way ball valve A is located at the first negative pressure position, the valve core of the three-way ball valve B is located at the first slurry suction position, and the slurry outlet 13 is in a closed state; when the valve core of the three-way ball valve A is located at the first positive pressure position, the valve core of the three-way ball valve B is located at the first slurry discharge position, and the slurry outlet 13 is in a closed state or an open state.

[0029] With this setting, when feeding slurry, the slurry outlet is closed, the three-way ball valve A is turned to the vacuum generating device to communicate with the tank body, and the three-way ball valve B is turned to the slurry inlet channel to communicate with the tank body; when discharging slurry, the three-way ball valve A is turned to the positive pressure device to communicate with the tank body, and the three-way ball valve B is turned to the safety valve to communicate with the tank body, and the slurry outlet is opened to realize slurry discharge. This structure does not change the structure and configuration of the tank body. It only needs to add two three-way valves to realize negative pressure slurry suction and positive pressure slurry discharge. This structure greatly improves the efficiency of slurry addition, reduces the labor intensity of workshop operators, and reduces the risk of secondary contamination of slurry. In this embodiment, the positive pressure device can specifically adopt a safety valve or a pressure pump, and one end of the slurry inlet channel is connected to the slurry barrel.

[0030] The three-way ball valve A is a T-type three-way ball valve, and the three-way ball valve B is an L-type three-way ball valve.

[0031] The T-type can interconnect three orthogonal pipelines and cut off the third channel, playing the role of diversion and merging, thereby adjusting the pressure value of the tank; the L three-way ball valve type can connect two orthogonal pipelines without keeping the third pipeline connected to each other, only playing a distribution role, and improving the stability of the on-off at the slurry inlet.

[0032] The three-way ball valve A is a manual ball valve.

[0033] The air port is controlled by a manual ball valve, and the fluid channel can be opened or closed by rotating the operating lever. This operation method is more convenient when the operation is complicated and is more flexible and effective than electric operation.

[0034] A plurality of mounting seats 21 are fixedly connected to the outer wall of the tank body 1 , a plurality of support rods 22 are fixedly connected to the bottom of the mounting seats 21 , and a moving wheel 23 is fixedly connected to the bottom of the support rods.

[0035] By arranging the mounting base, the support rod and the moving wheels, the device can be placed in a state that is easy to move and can be conveniently applied to different situations.

[0036] A window 3 is provided on one side of the tank body 1 .

[0037] The setting of the viewing window can quickly understand the amount of slurry inside the tank, making it easier to add material in time.

[0038] The top of the tank body 1 is provided with a flip cover slurry adding port 4.

[0039] The setting of the flip cover slurry adding port can be used for maintenance of the device and can also be used in emergency situations.

[0040] The three-way ball valve A is connected to the air port 12 by a clamp.

[0041] The three-way ball valve B is connected to the slurry inlet 11 by a clamp.

[0042] With this arrangement, without changing the structure and configuration of the tank body, the two three-way valves can be detachably connected to the tank body through the clamp, which is convenient and reliable.

[0043] The above disclosure is only a preferred embodiment of the present invention, and certainly cannot be used to limit the scope of rights of the present invention. Therefore, equivalent changes made according to the claims of the present invention are still within the scope covered by the present invention.
