Technical Field

[0001] The utility model relates to the technical field of sewage treatment, in particular to a low-pressure reverse osmosis sewage treatment device. Background Art

[0002] Reverse osmosis technology is a technology used to separate water from a solution through a reverse osmosis membrane. Because the direction of osmosis in this technology is opposite to the direction of natural osmosis, it is called reverse osmosis.

[0003] The existing processing device still has the following problems when in use:

[0004] The reverse osmosis device in the device needs to be cleaned or replaced with the reverse osmosis membrane in daily use. However, the treatment device needs to be stopped during the cleaning, and the sewage treatment cannot be continued. Utility Model Content

[0005] The purpose of the utility model is to solve the problem in the prior art that the reverse osmosis device in the device needs to be cleaned or replaced with the reverse osmosis membrane inside during daily use, but the treatment device needs to be stopped during cleaning, which makes it impossible to continue sewage treatment, and a low-pressure reverse osmosis sewage treatment device is proposed.

[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0007] A low-pressure reverse osmosis sewage treatment device, comprising two sets of reverse osmosis devices, for purifying sewage;

[0008] A shell, one side of the shell is provided with an input end, and the water inlet ends of the two reverse osmosis devices are respectively connected to the two sides of the input end through two connecting pipes;

[0009] A blocking component is used to block one of the connecting pipes. The blocking component is arranged inside the housing. The blocking component includes a limiting cylinder. A first water outlet is opened on a side of the limiting cylinder surface close to one of the connecting pipes. A second water outlet is opened on a side of the limiting cylinder surface close to the other connecting pipe. The first water outlet and the second water outlet are matched with the two connecting pipes respectively.

[0010] The transposition component is used to block another connecting pipe, and the transposition component is arranged inside the shell.

[0011] In a possible design, the inner wall of the shell is provided with two symmetrically arranged rectangular slide grooves, the outer wall of the limiting cylinder is fixedly provided with a slider, and the slider is slidably arranged inside one of the rectangular slide grooves.

[0012] In a possible design, the transposition assembly includes an annular chute opened on the inner wall of the shell near the reverse osmosis device, and one end of the two rectangular chute near the reverse osmosis device is connected to one side of the annular chute.

[0013] In a possible design, the inner wall of the annular slide groove is provided with two symmetrically arranged slots, a baffle is slidably provided on the inner wall of the slot, and a same compression spring is fixedly provided between one side of the baffle and the inner wall of the side close to the slot.

[0014] In a possible design, one side of the two baffles is configured as an inclined surface, and the two baffles are matched with the sliding block.

[0015] In a possible design, a threaded cylinder is fixedly provided on one side of the limiting cylinder close to the reverse osmosis device, a threaded rod is provided on the internal thread of the threaded cylinder, and one end of the threaded rod is rotated to penetrate the outside of the shell.

[0016] In the present application, during specific use, when sewage enters the interior of the shell through the input end, the sewage enters the two reverse osmosis devices through the No. 1 water outlet and the No. 2 water outlet respectively connected to the two connecting pipes for purification. When the reverse osmosis membrane inside the reverse osmosis device needs to be cleaned or replaced due to daily use, the threaded rod is turned counterclockwise, and the threaded rod drives the limit cylinder to move through the threaded cylinder (the slider at the bottom of the limit cylinder slides from the rectangular slide groove to the inside of the annular slide groove). At this time, the No. 2 water outlet is no longer connected to one of the connecting pipes, and all the sewage is temporarily passed through the No. 1 water outlet to enter the other reverse osmosis device for purification. At this time, the closed The reverse osmosis device on the upper part is cleaned and other operations are carried out. When it is finished, the threaded rod is rotated 180 degrees counterclockwise (when the slider at the bottom of the limit cylinder touches the baffle, the baffle is squeezed into the inside of the slot, and then the baffle is reset by the compression spring). At this time, the No. 1 water outlet and the No. 2 water outlet will be swapped, so that the sewage can enter the cleaned reverse osmosis device for purification, and the other group of reverse osmosis devices will become closed and can be cleaned and other operations. When everything is finished, the threaded rod is rotated in the opposite direction. Since the threaded rod touches the baffle, the limit cylinder becomes a sliding state and moves to the inside of another rectangular chute. At this time, the two connecting pipes will be reconnected.

[0017] In the utility model, the low-pressure reverse osmosis sewage treatment device can achieve the goal of blocking one of the reverse osmosis devices by rotating the threaded rod through the blocking component, and then it can be cleaned and operated. At this time, the sewage can temporarily pass through another set of reverse osmosis devices to ensure that the purification work can continue;

[0018] In the utility model, the low-pressure reverse osmosis sewage treatment device can achieve the purpose of exchanging two reverse osmosis devices that were originally in a disconnected state and a connected state by means of a transposition component, so that the other reverse osmosis device can continue to be cleaned without hindering the use of the device;

[0019] In the utility model, when in use, sewage enters two sets of reverse osmosis devices through two connecting pipes for purification operation. When it is necessary to clean the reverse osmosis device or replace the reverse osmosis membrane, one of the reverse osmosis devices can be blocked and cleaned by the blocking component;

[0020] After completion, the same operation can be continued on another set of reverse osmosis devices by means of a transposition assembly without interfering with the operation of the device. BRIEF DESCRIPTION OF THE DRAWINGS

[0034] In the above technical solution, during specific use, when the reverse osmosis membrane inside the reverse osmosis device 4 needs to be cleaned or replaced due to daily use, the threaded rod 5 is turned counterclockwise, and the threaded rod 5 drives the limiting cylinder 7 to move through the threaded cylinder 6 (the slider 10 at the bottom of the limiting cylinder 7 slides from the rectangular slide groove 11 to the inside of the annular slide groove 12). At this time, the No. 2 water outlet 9 is no longer connected to one of the connecting pipes 3, and all the sewage is temporarily passed through the No. 1 water outlet 8 to enter another reverse osmosis device 4 for purification. At this time, the closed reverse osmosis device 4 can be cleaned and other operations can be performed, and the sewage can temporarily pass through another set of reverse osmosis devices 4 to ensure that the purification work can continue.
