Description

Technical Field

[0001] The utility model relates to the technical field of microbial experiment equipment, in particular to a harmless treatment device for culture dishes. Background Art

[0002] When conducting microbial experiments, solid culture media are usually used. Generally, adding 1.5 - 2.5% of agar to the solid culture medium can make it solidify. For details, reference can be made to the Chinese patent "An anti-pollution electro-stimulated cell culture device" with the patent application number CN202120693677.3.

[0003] After experiments, culturing, counting, measuring and other operations, since the culture dishes after contacting microorganisms need to be harmlessly inactivated, experimental personnel need to manually pick out the solid culture medium and then throw it into a high-pressure sterilization bag, and separately sterilize the culture dishes and the culture medium.

[0004] However, for the above-mentioned manual separation method, first, during the process of picking out the culture medium, it takes a lot of time and effort for experimental personnel to operate, which is time-consuming and laborious; second, during the manual separation process, the staff is prone to scratching their hands, resulting in serious consequences such as infection, endangering the health of experimental personnel. Content of the Utility Model

[0005] The first technical problem to be solved by the utility model is to provide a harmless treatment device for culture dishes that is time-saving and labor-saving in operation according to the current situation of the prior art.

[0006] The second technical problem to be solved by the utility model is to provide a harmless treatment device for culture dishes with safe operation.

[0007] The technical solution adopted by the utility model to solve the above first technical problem is as follows: A harmless treatment device for culture dishes, characterized by comprising:

[0008] A frame;

[0009] Two belt pulleys arranged at intervals, each belt pulley is rotatably connected to the frame;

[0010] A conveyor belt, wound around the outer circumferences of the two belt pulleys and capable of running circuitously with the rotating belt pulleys, and having a plurality of positioning grooves on the surface for accommodating culture dishes; and

[0011] A heating body, used for heating the culture dishes so that the culture medium containing agar in the culture dishes melts and naturally falls under the action of gravity.

[0012] In order to heat the culture dishes, the heating body includes

[0013] The heat conducting column is suspended below the conveyor belt, extends along the advancing direction of the conveyor belt, and has a mounting hole extending along its length direction inside; and

[0014] The resistance wire is installed in the mounting hole described above.

[0015] In order to facilitate the suspension of the heat conducting column below the conveyor belt, the pulley is rotatably connected to the frame through a rotating shaft;

[0016] Both ends of the heat conducting column have first hanging brackets extending upward. The first hanging brackets correspond to the pulleys one by one, and each first hanging bracket is hung on the rotating shaft of the corresponding pulley.

[0017] In order to realize the automatic operation of the conveyor belt, a driving member is further included. The driving member is installed on the frame, and its power output shaft is coaxially connected to one of the pulleys to drive the pulley to rotate.

[0018] In order to facilitate the reception of the culture medium, a material receiving groove is further included. The material receiving groove is located directly below the conveyor belt and is used to receive the culture medium that falls naturally.

[0019] In order to facilitate the collection of the culture medium, the bottom surface inside the material receiving groove gradually decreases from back to front.

[0020] In order to facilitate the discharge of the culture medium, the front side of the material receiving groove has an opening to form an outlet of the material receiving groove.

[0021] In order to facilitate the suspension of the material receiving groove below the conveyor belt, the pulley is rotatably connected to the frame through a rotating shaft;

[0022] Both ends of the material receiving groove have second hanging brackets extending upward. The second hanging brackets correspond to the pulleys one by one, and each second hanging bracket is hung on the rotating shaft of the corresponding pulley.

[0023] In order to further solve the above-mentioned second technical problem, a flexible sleeve is provided in the positioning groove for the culture dish to be embedded therein.

[0024] In order to give the flexible sleeve enough deformation space, there is a gap between the outer peripheral wall of the flexible sleeve and the inner peripheral wall of the positioning groove.

[0025] Compared with the prior art, the advantages of the present utility model are as follows:

[0026] First, by placing the culture dish in the positioning groove of the conveyor belt and using a heating body to heat the culture dish, the solid culture medium containing agar in the culture dish is melted and naturally falls under the action of gravity, realizing the rapid separation of the culture medium and the culture dish. There is no need for manual scooping out, which saves time and effort. Moreover, the culture medium falls off automatically after being heated, which is cleaner than scooping out in the solid state of the culture medium manually;

[0027] Second, due to the setting of the flexible sleeve, when the experimenter places the petri dish without a lid into the positioning groove of the conveyor belt, it can be inserted with little force. And during the whole process of removing the solid culture medium in the petri dish, the experimenter only needs to pick it up and put it in, without causing an infection risk to the experimenter, thus ensuring the life and health of the experimenter.

However, these terms are used here only for the convenience of description and are determined based on the example orientations shown in the drawings. Since the embodiments disclosed by the present utility model can be arranged in different directions, these terms indicating directions are only for illustration and should not be regarded as limitations. For example, "upper" and "lower" are not necessarily limited to the directions opposite to or consistent with the direction of gravity.

[0033] As Figures 1 to 3 shown, it is a preferred embodiment of the device for harmless treatment of petri dishes of the present utility model. The device for harmless treatment of petri dishes includes a frame 1, belt pulleys 2, a conveyor belt 3, a heating element 4, a driving member 5, and a receiving trough 6.

[0034] Among them, the number of belt pulleys 2 is two, and they are arranged at intervals in the left - right direction. Each belt pulley 2 is rotatably connected to the frame 1 through a rotating shaft 21;

[0035] The conveyor belt 3 is wound around the outer peripheries of the two belt pulleys 2 and can run circuitously with the rotating belt pulleys 2. Specifically, the surface of the conveyor belt 3 has a plurality of positioning grooves 31; a flexible sleeve 32 is provided in each positioning groove 31 for a petri dish to be embedded therein, and there is a gap 320 between the outer peripheral wall of the flexible sleeve 32 and the inner peripheral wall of the positioning groove 31. In this embodiment, the flexible sleeve 32 is made of rubber material.

[0036] The heating element 4 is used to heat the petri dish so that the agar-containing culture medium in the petri dish melts and naturally falls under the action of gravity. In this embodiment, the heating element 4 includes a heat conducting column 41 and a resistance wire 42. Specifically, the heat conducting column 41 extends in the left-right direction; the interior of the heat conducting column 41 has a mounting hole 411 extending along its length direction; both ends of the heat conducting column 41 have first hanging brackets 412 extending upward, and the first hanging brackets 412 correspond to the above-mentioned pulleys 2 one by one, and each first hanging bracket 412 is hung on the rotating shaft 21 of the corresponding pulley 2, so as to realize the suspension of the heat conducting column 42 below the conveyor belt 3; the resistance wire 42 is installed in the mounting hole 411 to generate heat.

[0037] The driving member 5 is a motor, which is installed on the frame 1, and its power output shaft is coaxially connected to the rotating shaft 21 of the pulley 2 on the right side to drive the pulley 2 to rotate.

[0038] The material receiving groove 6 is located directly below the conveyor belt 3 and is used to receive the naturally falling culture medium. In this embodiment, the bottom surface inside the material receiving groove 6 gradually decreases from back to front, and the front side of the material receiving groove 6 has an opening 61 to form the outlet of the material receiving groove 6; both ends of the material receiving groove 6 have second hanging brackets 62 extending upward, and the second hanging brackets 62 correspond to the above-mentioned pulleys 2 one by one, and each second hanging bracket 62 is hung on the rotating shaft 21 of the corresponding pulley 2, so as to realize the suspension of the material receiving groove 6 below the conveyor belt 3.

[0039] The working principle of this embodiment is as follows: During operation, the experimenter first inserts the petri dish to be processed into the flexible sleeve 32 inside each positioning groove 31, and then starts the heating element 4 and the driving member 5. The driving member 5 drives the pulley 2 to rotate, and then drives the conveyor belt 3 to run circuitously. During this process, the heating element 4 heats the petri dish (the melting point of agar is 96 °C and the freezing point is 40 °C. By setting the heating element 4, the solid culture medium in the petri dish is heated to the melting point of agar), so that the culture medium in the petri dish melts and naturally falls into the material receiving groove 6 under the action of gravity, and finally slides into the set trash can through the opening 61 on the front side of the material receiving groove 6, realizing the rapid separation of the culture medium and the petri dish; in addition, due to the setting of the flexible sleeve 32, when the experimenter places the lidless petri dish in the positioning groove 31 of the conveyor belt 3, it can be inserted with little force, and during the whole process of removing the solid culture medium from the petri dish, the experimenter only needs to pick it up and put it in, without posing an infection risk to the experimenter, ensuring the life and health of the experimenter.
