The first wax collecting groove 2 is arranged in the second chamber 20, a first wax collecting opening 21 is arranged on the first wax collecting groove 2, the first wax collecting opening 21 is located at the upper part of the cavity, the first wax collecting opening 21 is communicated with a first wax collecting pipeline 212, and the first wax collecting pipeline 212 penetrates through the cavity and then is connected with an external wax collecting device.

As an alternative embodiment, the second partition plate 201 is provided with a first through hole, the first through hole is used for penetrating through the first communicating pipe 302, and the first communicating pipe 302 communicates the second chamber 20 and the third chamber 30; wherein the outlet position of the first communicating pipe 302 is higher than the inlet position thereof.

Further, the wax removing device further comprises: the third partition plate 301, the second wax collecting groove 3 and the second communicating pipeline 401; the first partition plate 101, the third partition plate 301 and the second partition plate 201 are vertically disposed in the cavity, and collectively divide the cavity into the first chamber 10, the second chamber 20, the fourth chamber 40 and the third chamber 30.

In a preferred embodiment, the height of the first partition 101, the third partition 301 and the second partition 201 is no more than four fifths of the height of the wax removal tank 100.

The second wax collecting groove 3 can be arranged in the following two possible implementation modes:

one possible implementation is: as shown in fig. 3 and 4, the second wax collecting groove 2 is arranged in the fourth chamber 40, and the second wax collecting groove 3 is provided with a second wax collecting opening 31; the third partition plate 301 is provided with a second through hole, the second through hole is used for penetrating through the converging pipeline 211, and the second wax receiving opening 31 and the first wax receiving pipeline 212 are communicated through the converging pipeline 211.

Specifically, as shown in fig. 7, the first wax collecting port 21 of the first wax collecting groove 2 is communicated with the second wax collecting port 31 of the second wax collecting groove 3 through a merging pipe 211, and is communicated with a first wax collecting pipe 212.

Another possible implementation is: the second wax collecting groove 2 is arranged in the fourth cavity 40, and a second wax collecting opening 31 is formed in the second wax collecting groove 3; the second wax collecting port 31 is located at the upper part of the cavity, and the second wax collecting port 31 is communicated with the external wax collecting device in the same way as the first wax collecting port 21 is communicated with the external wax collecting device (not shown in the figure).

As an optional implementation manner, the third partition plate 301 is further provided with a third through hole, the third through hole is used for penetrating through a second communicating pipeline 401, and the second communicating pipeline 401 communicates the second chamber 20 and the fourth chamber 40; the outlet position of the second communicating pipe 401 is higher than the inlet position thereof.

It should be noted that the outlet positions of the first communicating channel 302 and the second communicating channel 401 are higher than the inlet positions thereof in order to increase the static stratification effect of the solution in the fourth chamber 40 and the second chamber 20 communicated with the inlet of the first communicating channel 302 and the inlet of the second communicating channel 401. Taking the second communicating pipe 401 as an example, the inlet of the second communicating pipe 401 is communicated with the second chamber 20, and the outlet is communicated with the fourth chamber 40, so that the solution moves upward in the second communicating pipe 401 from the second chamber 20 to the fourth chamber 40, that is, when the liquid level of the solution in the second chamber 20 is higher than the outlet of the second communicating pipe 401, the solution can be discharged from the outlet of the second communicating pipe 401, and before the liquid level of the solution in the second chamber 20 does not reach the outlet of the second communicating pipe 401, the solution cannot enter the fourth chamber 40 in the second chamber 20, so that the residence time of the solution in the second chamber 20 is increased, and the wax and the precipitated impurities in the solution can be fully layered, this facilitates the passage of the centrally located solution containing the least impurities from the second communication channel 401 into the fourth chamber 40.

It should be noted that, as shown in fig. 4, the first communicating pipe 302 and the second communicating pipe 401 may be arranged at opposite angles, so as to increase the flow path of the solution, prolong the settling separation time, and further promote the layering effect of the solution. For example, when the first communicating pipe 302 is disposed near one side of the wax collecting pipe 100, the first communicating pipe 302 is disposed near the other side of the wax collecting pipe 100.

In addition, in order to detect the temperature and the liquid level in the dewaxing tank 100, a plurality of temperature monitoring devices such as thermometers and liquid level monitoring devices such as liquid level meters (not shown in the figure) can be arranged, and the number and the specific types of the temperature monitoring devices and the liquid level monitoring devices are not limited in the embodiment.

As an alternative embodiment, the outlet positions of the first communication channel 302 or/and the second communication channel 401 may be respectively provided with a limiting mechanism 6; the limiting mechanism 6 comprises a driving member 601 and a blocking piece 602, the blocking piece 602 is disposed inside the first communicating pipe 302 or/and the second communicating pipe 401, and the driving member 601 is connected with the blocking piece 602 and drives the blocking piece 602 to rotate in the horizontal direction by using the driving member 601 as a rotating shaft.

Specifically, taking the first communicating pipe 302 and the limiting mechanism 6 as an example, as shown in fig. 5 and 6, the limiting mechanism 6 is detachably connected inside the first communicating pipe 302 at the outlet position, for example, by hinge, screw connection, pin connection or snap connection, wherein the present embodiment does not limit the specific structure of the detachable connection.

It should be noted that the blocking plate 602 may be a semi-circular thin plate structure, and the diameter of the blocking plate 602 is slightly smaller than the diameter of the first communicating pipe 302, so that the liquid passing flow rate in the first communicating pipe 302 can be adjusted to the maximum. However, the present invention is not limited to the specific shape and size of the baffle 602, and is not limited to the above examples.

Because the first wax receiving groove 2 and the second wax receiving groove 3 are fixed in position, when the wax content in the wax removing tank 100 is high, in order to prevent a part of wax from overflowing into the first wax receiving groove 2 or/and the second wax receiving groove 3, the driving member 601 drives the blocking piece 602 to rotate in the horizontal direction by using the driving member 601 as a rotating shaft, and when the position relationship between the blocking piece 602 and the first communicating pipeline 302 is shown in fig. 6, the blocking piece 602 blocks a part of liquid flow at the outlet of the first communicating pipeline 302, so that the liquid level in the second chamber 20 and the fourth chamber 40 rises, the wax overflows into the first wax receiving groove 2 or/and the second wax receiving groove 3, and the wax receiving effect is improved.

The working principle of the connection of the second communicating channel 401 and the limiting mechanism 6 is the same as that of the first communicating channel 302, and the same technical effect can be achieved, and the detailed description is omitted here.

It should be noted that, according to the requirements of the practical application scenario, the limiting mechanism 6 may be disposed only on the first communicating pipe 302, only on the second communicating pipe 401, or both the first communicating pipe 302 and the second communicating pipe 401, as long as the effect of increasing the liquid level is achieved, which is not limited in the present invention.

In addition, a limiting portion (not shown in the drawings) may be further disposed in the limiting mechanism 6, and the limiting portion may be a positioning pin or a blocking protrusion disposed on an inner wall of the first communicating pipe 302 and close to the blocking piece 602, as long as the limiting portion can function to limit the rotation angle of the blocking piece 602, and the invention is not limited to this, and is not limited to the above example.

It should be noted that the second end of inlet channel 1 is the form of buckling upwards and can make solution not straight inflow when getting into first cavity through inlet channel 1, and the form of buckling upwards through the setting can make the flow velocity when solution gets into first cavity slow down, avoids causing great disturbance to the solution in the first cavity, and has reduced thereby to produce the corruption to the inner wall that the wax removal jar body 1 causes the impact.

In addition, this wax removal device still includes: a liquid outlet pipeline 5; the liquid outlet pipe 5 is communicated with the liquid outlet of the third chamber 30, the first end of the liquid outlet pipe 5 is positioned in the third chamber 30 of the wax removal tank 100, and the second end of the liquid outlet pipe 5 is positioned outside the wax removal tank 100.

Normally, the first outlet pipe 501 is closed, the second outlet pipe 502 is opened, and the lower second outlet pipe 502 can prevent the problem that the un-cleaned wax is discharged from the outlet pipe 5 together and blocks the outlet pipe.

It should be noted that when one of the first liquid outlet pipe 501 and the second liquid outlet pipe 502 fails, the other one can be used as a spare liquid outlet pipe to work normally, so as to avoid the situation that the solution in the dewaxing tank 100 cannot flow out.

As an alternative embodiment, the first outlet pipe 501 and the second outlet pipe 502 are respectively provided with a first control valve 5011 and a second control valve 5021. It should be noted that the first control valve 5011 and the second control valve 5021 can adjust the flow rate of the solution in the first outlet pipe 501 and the second outlet pipe 502, and can also open and close the first outlet pipe 501 and the second outlet pipe 502, and the specific functions of the first control valve 5011 and the second control valve 5021 are not limited, and are not limited to the above examples.
