Description

Technical Field

[0001] The invention relates to a liquid medicine pool circulation system, in particular to a roll-type film washing and developing liquid medicine pool circulation system, belonging to the field of photosensitive film washing and developing equipment. Background Art

[0002] The structure of existing roll-type photosensitive film processing machines generally includes a developing tank, a fixing tank, a washing tank, a drying tank, a blowing chamber, a heating chamber, etc. Generally, during the processing, the developing and fixing liquids are placed in the corresponding developing tank and fixing tank, and the film is developed and fixed by controlling the time and immersion depth of the film passing through the developing tank and the fixing tank. In this method, the liquid level of the developing tank and the fixing tank changes due to the entry and exit of the washing bracket and the film, and the film movement and adhesion of the liquid, resulting in inconsistent time periods for the continuously moving roll film to be immersed in the developing liquid and the fixing liquid, affecting the film processing and developing effect. At the same time, chemical reactions occur during the contact between the film and the liquid, which affects the performance of the local liquid.

[0003] Therefore, how to achieve consistency in the time when the film enters the developer tank and the fixer tank, and at the same time achieve uniform and stable performance of the chemical solution during the washing process is a problem that has always been solved in the roll film washing process. Summary of the invention

[0004] The technical problem to be solved by the present invention is to provide a roll-type film washing and developing liquid pool circulation system, which solves the problem in the prior art that the liquid in the developing tank or / and the fixing tank is lost due to the change in liquid level caused by the entry and exit of the washing bracket and the film, resulting in inconsistent liquid treatment time and uneven chemical reaction of the liquid.

[0005] The technical solution of the present invention to solve the above technical problems is as follows: a roll-type photosensitive film washing and developing liquid pool circulation system, comprising a main liquid tank body, an auxiliary liquid tank body, a main liquid outlet circulation pipe, an auxiliary liquid outlet circulation pipe, a circulation connecting pipe, a one-way valve and a circulation pump, wherein the upper end of the main liquid tank body is provided with an overflow port, and the overflow port is connected to the auxiliary liquid tank body;

[0006] The inlet end of the main medicine liquid outlet circulation pipe is connected to the bottom of the main medicine liquid tank body and is connected; the inlet end of the auxiliary medicine liquid outlet circulation pipe is connected to the bottom of the auxiliary main medicine liquid tank body and is connected; one end of the circulating connecting pipe is connected to the outlet ends of the main medicine liquid outlet circulation pipe and the auxiliary medicine liquid outlet circulation pipe, and the other end is connected to the upper part of the main medicine liquid tank body; the one-way valve is installed on the auxiliary medicine liquid outlet circulation pipe and its liquid flow direction is from the inlet end to the outlet end of the auxiliary medicine liquid outlet circulation pipe; the circulating pump is installed on the circulating connecting pipe.

[0007] The beneficial effects of the present invention are as follows: the present invention ensures that the liquid level of the main liquid tank body in contact with the film is kept constant during the movement of the roll-type photosensitive film through the liquid support at a uniform speed, because the main liquid outlet circulation pipe and the auxiliary liquid outlet circulation pipe are connected to the main liquid tank body and the bottom of the auxiliary liquid tank body at the same time, and the circulation pump only converges to the main liquid tank body, thereby ensuring that the liquid level of the main liquid tank body in contact with the film is kept constant, and ensuring that the time for each part of the continuously moving film to be immersed in the liquid is kept consistent. At the same time, the liquid is stirred by the flow of the liquid, thereby improving the uniform contact between the film and the liquid, and improving the stability of the chemical reaction between the liquid and the film.

[0008] Based on the above technical solution, the present invention can also be improved as follows.

[0009] Furthermore, it also includes a first solenoid valve, which is installed on the circulation connecting pipe between the main medicine liquid outlet circulation pipe and the circulation pump to simultaneously return the liquid in the main medicine liquid tank body and the auxiliary medicine liquid tank body from the bottom thereof to the top of the main medicine liquid tank body.

[0010] Furthermore, it also includes a liquid medicine tank, which is connected to the circulation connecting pipe between the circulation pump and the first solenoid valve through a connecting pipe.

[0011] Furthermore, it also includes a second solenoid valve, which is installed on the connecting pipe.

[0012] Furthermore, the liquid level of the medicine liquid tank is lower than the bottom of the main medicine liquid tank body and the auxiliary medicine liquid tank body.

[0013] Furthermore, the main medicine liquid tank body and the auxiliary medicine liquid tank body are integrally formed and share a wall plate, and the upper end of the wall plate is the overflow port.

[0014] Furthermore, it also includes a filter box, which is installed at the upper end of the main liquid medicine tank and the inlet of which is connected to the other end of the circulation connecting pipe.

DETAILED DESCRIPTION

[0022] The principles and features of the present invention are described below in conjunction with the accompanying drawings. The examples given are only used to explain the present invention and are not used to limit the scope of the present invention.

[0023] like Figure 1-2 As shown, according to an embodiment of the present invention, a roll-type photosensitive film washing and developing liquid pool circulation system comprises a main liquid tank body 1, an auxiliary liquid tank body 2, a main liquid outlet circulation pipe 3, an auxiliary liquid outlet circulation pipe 4, a circulation connecting pipe 6, a one-way valve 5 and a circulation pump 7. An overflow port 131 is provided at the upper end of the main liquid tank body 1, and the overflow port 131 is connected to the auxiliary liquid tank body 2;

[0024] The inlet end of the main liquid medicine outlet circulation pipe 3 is connected to the bottom of the main liquid medicine tank body 1 and is connected; the inlet end of the auxiliary liquid medicine outlet circulation pipe 4 is connected to the bottom of the auxiliary main liquid medicine tank body 1 and is connected; one end of the circulation connecting pipe 6 is connected to the outlet ends of the main liquid medicine outlet circulation pipe 3 and the auxiliary liquid medicine outlet circulation pipe 4, and the other end is connected to the upper part of the main liquid medicine tank body 1; the one-way valve 5 is installed on the auxiliary liquid medicine outlet circulation pipe 4 and its liquid flow direction is from the inlet end to the outlet end of the auxiliary liquid medicine outlet circulation pipe 4; the circulation pump 7 is installed on the circulation connecting pipe 6.

[0025] Therefore, the medicine in the main medicine liquid outlet circulation pipe 3 and the auxiliary medicine liquid outlet circulation pipe 4 of the embodiment of the present invention can be collected through two ways through the circulation pump 7 and enter the main medicine liquid tank body 1. At the same time, the one-way valve ensures that the medicine in the main medicine liquid tank body 1 will not enter the auxiliary medicine liquid tank body 2 through the main medicine liquid outlet circulation pipe 3 and the auxiliary medicine liquid outlet circulation pipe 4, and ensures that the amount of medicine entering the main medicine liquid tank body 1 is the sum of the amount of liquid flowing out of the main medicine liquid outlet circulation pipe 3 and the auxiliary medicine liquid outlet circulation pipe 4. In this way, it is fully guaranteed that the medicine level in the main medicine liquid tank body 1 is stable at the highest position. At the same time, when the medicine is drawn out through the main medicine liquid outlet circulation pipe 3 and the auxiliary medicine liquid outlet circulation pipe 4 and converged above the main medicine liquid tank body 1 into the main medicine liquid tank body 1, the uniformity of the medicine performance is ensured, and the time for the uniformity of the medicine mixing is shortest.

[0026] Specifically, it can also include a first solenoid valve 8, which is installed on the circulation connecting pipe 6 between the main medicine liquid outlet circulation pipe 3 and the circulation pump 7 to simultaneously return the liquid in the main medicine liquid tank body 1 and the auxiliary medicine liquid tank body 2 from the bottom to the top of the main medicine liquid tank body 1. Therefore, the first solenoid valve 8 can switch the connection between the main medicine liquid tank body 1, the auxiliary medicine liquid tank body 2 and the circulation pump 7 to control the circulation time of the medicine liquid.

[0027] In some specific embodiments, a liquid medicine tank 10 is included, and the liquid medicine tank 10 is connected to the circulation connecting pipe 6 between the circulation pump 7 and the first electromagnetic valve 8 through a connecting pipe 11. Specifically, a second electromagnetic valve 9 is also included, and the second electromagnetic valve 9 is installed on the connecting pipe 11.

[0028] Specifically, the liquid level of the liquid medicine tank 10 is lower than the bottom of the main liquid medicine tank 1 and the auxiliary liquid medicine tank 2. Thus, the liquid medicine in the main liquid medicine tank 1 and the auxiliary liquid medicine tank 2 can be recovered into the liquid medicine tank 10 by gravity, which has a simple structure and is easy to operate.

[0029] Specifically, the main liquid medicine tank body 1 and the auxiliary liquid medicine tank body 2 are integrally formed and share a wall plate 13, and the upper end of the wall plate 13 is an overflow port 131. Therefore, the flux of the overflow port 131 can be set larger, ensuring that the liquid with the highest liquid level quickly overflows into the auxiliary liquid medicine tank body 2, ensuring that the highest liquid level in the main liquid medicine tank body 1 is accurate and consistent.

[0030] In some examples, a filter box 12 is further included. The filter box 12 is installed at the upper end of the main liquid medicine tank 1 and the inlet of the filter box 12 is connected to the other end of the circulation connecting pipe 6.

[0031] Specifically, the circulation pump 7 is a peristaltic pump. Thus, the function of circulating and recovering the liquid medicine can be realized during the forward and reverse switching of the peristaltic pump.

[0032] The present invention also provides a roll-type photosensitive film developing and imaging processing machine, which comprises the above-mentioned roll-type photosensitive film developing and imaging liquid pool circulation system.

[0033] Furthermore, the roll-type photosensitive film washing and developing liquid tank circulation system is composed of multiple groups; the main liquid tank body and the auxiliary liquid tank body 2 in each group can be the main liquid tank body 1 and the auxiliary liquid tank body 2 of the developing tank; the main liquid tank body 1 and the auxiliary liquid tank body 2 of the fixing tank.

[0034] The working process of the roll-type photosensitive film washing and developing liquid medicine pool circulation system of the present invention is as follows:

[0035] The main medicine liquid tank body of the present invention and the auxiliary medicine liquid tank body 2 are connected at the bottom with a main medicine liquid outlet circulation pipe 3 and an auxiliary medicine liquid outlet circulation pipe 4. A one-way flow valve is provided on the auxiliary medicine liquid outlet circulation pipe 4. It is connected to the top of the main medicine liquid tank body through a circulation connecting pipe 6 and a peristaltic pump is installed thereon to form a medicine liquid circulation. The main medicine liquid tank body is connected to the bottom of the auxiliary medicine liquid tank body 2 through the inlet of the peristaltic pump.

[0036] The second path can be connected to the medicine liquid tank 10 at a lower position below the main medicine liquid tank body and the auxiliary medicine liquid tank body 2, so as to realize the absorption and release of the medicine liquid in the medicine liquid tank 10 and return to the medicine liquid tank 10.

[0037] When the second valve is opened, the first valve is closed, and the peristaltic pump moves to form water absorption; the liquid medicine can be drawn from the liquid medicine tank 10 to the main liquid medicine tank; when the inner cavity of the main liquid medicine tank body 1 is filled, the liquid medicine overflows through the partition to the inner cavity of the auxiliary liquid medicine tank body 2. The flow rate and flow velocity of the peristaltic pump can control the time of liquid medicine extraction, thereby controlling the dosage of liquid medicine extraction.

[0038] When the liquid medicine extraction reaches the preset amount, the second valve is closed, the first valve is opened, and the peristaltic pump continues to move, so that the liquid medicine flowing from the main liquid medicine tank body 1 to the auxiliary liquid medicine tank body 2 forms a loop through the peristaltic pump, and the liquid medicine flowing from the main liquid medicine tank body 1 to the auxiliary liquid medicine tank body 2 is extracted into the main liquid medicine tank body 1, and the overflow port 131 is used to ensure that the liquid medicine level of the main liquid medicine tank body is kept at the same level as the overflow port 131, that is, the liquid medicine in the main liquid medicine tank body 1 is always fully loaded. By controlling the liquid level of the main liquid medicine tank body 1, it is ensured that the time for each unit length of the roll-type photosensitive film to be released in the liquid medicine is consistent during the uniform speed movement through the liquid medicine bracket. At the same time, the liquid medicine is stirred by the flow of the liquid medicine, which improves the uniform contact between the film and the liquid medicine, and improves the stability of the chemical reaction between the liquid medicine and the film.

[0039] When the film is developed, the second valve is opened, the first valve is opened, and the peristaltic pump moves in the reverse direction. Natural gravity can be used to naturally return the liquid medicine in the liquid medicine tank to the liquid medicine tank 10 at a lower position below, completing the recovery of the liquid medicine. The reverse movement of the water pump can promote the reflux of all the residual liquid medicine in the pipeline.

[0040] After all the liquid medicine is recovered, the nozzle of the liquid medicine tank 10 is inserted into the sewer pipe to cooperate with the flushing and cleaning work of the liquid medicine tank and the liquid medicine pipeline after the film washing work is completed.

[0041] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
