Description

Technical Field

[0001] The invention relates to the field of waste sample treatment, in particular to a clinical medical waste sample treatment device. Background Art

[0002] In the prior art, the common method for treating waste samples in clinical medicine is incineration. The incineration method is mature in technology and can disinfect and sterilize thoroughly, but it has the following disadvantages:

[0003] 1. Since there are many types of waste samples and they are of different sizes, it is not easy to burn large-volume waste samples fully when they are directly thrown into the incinerator for incineration, and the incineration efficiency is low. Therefore, relevant technologies have made improvements to this. For example, patents such as CN202111284851.X and CN202010522513.4 all choose to crush the waste samples before proceeding to the next step. However, although the crushed waste samples are easier to incinerate, different types of waste samples have different degrees of dryness and wetness. Wet waste samples are also not easy to incinerate. Wet waste samples cannot be dried simply by crushing;

[0004] 2. Incineration of waste samples will produce high-temperature exhaust gas, which is currently mostly discharged directly, so the heat in the exhaust gas is directly wasted. Moreover, these exhaust gases are often mixed with ashes and some odors, which can easily cause certain pollution to the atmospheric environment. Summary of the invention

[0039] In the description of the present invention, "first feature" and "second feature" may include one or more of the features. In addition, the terms "first" and "second" are used for descriptive purposes only and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features.

[0040] like Figure 1-Figure 6 The clinical medical waste sample treatment device shown comprises: a base 1, a treatment box, a crushing mechanism, a spiral conveying mechanism, an incineration mechanism, a waste heat drying mechanism and a purification mechanism.

[0041] A universal wheel 2 is provided at the bottom of the base 1, that is, the base 1 in the device is a mobile base 1, thereby improving the position flexibility of the device.

[0042] like Figure 1-Figure 4 As shown, the processing box is fixed on the base 1 by a bracket, and the processing box includes a crushing box 3 on the upper side and a conveying box 4 on the lower side. The crushing box 3 is provided with an addition port, and the bottom of the conveying box 4 is provided with a discharge port; the crushing mechanism includes a first driving member and a crushing wheel 5, and there are two crushing wheels 5 which are arranged side by side in the crushing box 3. The first driving member is connected to the two crushing wheels 5 to drive the two crushing wheels 5 to rotate in opposite directions; the spiral conveying mechanism includes a second driving member and a spiral conveying shaft 6, and the spiral conveying shaft 6 is rotatably arranged in the conveying box 4, and the second driving member is connected to the spiral conveying shaft 6.

[0043] Specifically, considering that the waste samples in clinical medicine are large and small, in order to facilitate the subsequent sufficient incineration treatment, the pulverizing mechanism first pulverizes these waste samples uniformly and pulverizes them into particles of similar size, so that the subsequent incineration will be more sufficient. Then the pulverized waste samples will fall into the conveying box 4 below, and then the spiral conveying mechanism will convey the waste samples to the discharge port and discharge the treatment box, thereby completing the preliminary treatment of the waste samples before incineration.

[0044] Since waste samples in clinical medicine are of different types, many of which are wet, the use of a spiral conveying mechanism can effectively convey all types of dry and wet waste samples. In addition, the spiral conveying mechanism has a simple and compact structure and occupies little space.

[0045] like Figure 1-Figure 4 As shown, the incineration mechanism includes an incinerator 7 fixed on a base 1, a discharge pipe 8 is provided at the discharge port, and the discharge pipe 8 is connected to the incinerator 7; the waste heat drying mechanism includes an exhaust pipe 9, which is connected to the incinerator 7 and is bent into a spiral shape and wound around the conveying box 4.

[0046] Specifically, the device still adopts the incineration method to destroy clinical medical waste samples, but the high-temperature exhaust gas in the incineration process is not discharged directly, but flows into the spiral exhaust pipe 9 wrapped around the conveying box 4. In the process of flowing along the exhaust pipe 9, the heat of the high-temperature exhaust gas can be transferred to the waste samples being transported in the conveying box 4, thereby achieving drying and preheating of the waste samples, helping to reduce the humidity of the waste samples and making the waste samples dry. Such dry waste samples will be easier to be incinerated in the incinerator 7, reducing the energy consumption of the incinerator 7.

[0047] Since the exhaust pipe 9 is spirally wound around the conveying box 4, the flow path of the high-temperature exhaust gas is extended, thereby increasing the heat exchange time between the high-temperature exhaust gas and the waste sample, helping to improve the utilization efficiency of the heat in the high-temperature exhaust gas and reduce heat waste.

[0048] like Figure 4 and Figure 6 As shown, the purification mechanism includes a water washing component and a purification component. The exhaust pipe 9 is connected to the water washing component. The water washing component is used to wash and clean the exhaust gas. The purification component is connected to the downstream side of the water washing component. The purification component is used to then dry and purify the exhaust gas.

[0049] Specifically, in addition to carrying a lot of heat, the above-mentioned high-temperature exhaust gas is often mixed with a lot of ashes and unpleasant odors. Direct discharge will pollute the environment. Therefore, when the waste heat of the high-temperature exhaust gas is utilized and the temperature drops, the device is also equipped with a purification mechanism to further process the exhaust gas.

[0050] The purification mechanism first uses a water washing component to wash the exhaust gas to mainly remove the ash in the exhaust gas. This water washing method is simple, low-cost and easy to implement. The exhaust gas is then dried and purified through the purification component to dry the gas and remove the odor of the exhaust gas. After the exhaust gas is purified, the pollution to the atmospheric environment can be reduced when it is discharged.

[0051] The use of this device is as follows:

[0052] The clinical medical waste samples to be processed are placed in the crushing box 3 for crushing, and then fall into the conveying box 4. The waste samples are conveyed to the discharge port by the spiral conveying mechanism and fall into the incinerator 7 for incineration. The high-temperature waste gas generated during incineration will flow into the spiral exhaust pipe 9 wound around the conveying box 4 to dry and preheat the waste samples being conveyed in the conveying box 4.

[0053] After heat exchange and cooling, the exhaust gas finally passes through a water washing component to remove ash, and then passes through a purification component to dry and purify it before being discharged.

[0054] In further settings, such as Figure 3 and Figure 4 As shown, the first driving member includes a first motor 12 and a transmission gear 13. The first motor 12 is fixedly arranged outside the crushing box 3. The axle of each crushing wheel 5 extends outward from the processing box and is respectively fixed with a transmission gear 13. The two transmission gears 13 are meshed, and the first motor 12 is connected to one of the transmission gears 13. Therefore, the first motor 12 can drive the two crushing wheels 5 to rotate in opposite directions through the transmission gear 13 to crush the waste sample.

[0055] like Figure 4 and Figure 5As shown, the second driving member includes a second motor 14, which is fixedly arranged outside the conveying box 4 and connected to the screw conveying shaft 6. The screw conveying shaft 6 is a conveying shaft with spiral blades. The first motor 12 and the second motor 14 can be speed-adjustable motors, and the motor speed can be adjusted according to actual working conditions.

[0056] like Figure 1-Figure 4 As shown, the conveying box 4 is a horizontally arranged cylindrical box, a crushing box 3 is provided on the upper left side of the conveying box 4, a discharge pipe 8 is provided on the lower right side, and an exhaust pipe 9 is spirally wound around the portion of the conveying box 4 located between the crushing box 3 and the discharge pipe 8, thereby facilitating the exhaust pipe 9 and the conveying box 4 to have as large a heat exchange area as possible.

[0057] like Figure 1-Figure 4 As shown, a blower 15 is integrated on the incinerator 7 to facilitate the introduction of fresh air into the incinerator 7 to assist in incineration.

[0058] like Figure 6 As shown, the water washing assembly includes a water washing box 10, which is filled with a certain amount of water. The exhaust pipe 9 is inserted downward into the water washing box 10 and extends below the liquid surface. The water washing box 10 is provided with a ventilation pipe 16 connected to the purification assembly, and the pipe mouth of the ventilation pipe 16 is located above the liquid surface. Therefore, when the exhaust gas floats up, it will be washed and cleaned to remove impurities such as ash mixed in it.

[0059] The purification assembly includes a purification box 11, in which a drying layer 17 and a purification layer 18 located at the downstream side of the drying layer 17 are arranged. The drying layer 17 is composed of two first air-permeable nets arranged oppositely and a desiccant filled between the two first air-permeable nets. The desiccant can be a silica gel desiccant. The purification layer 18 is composed of two second air-permeable nets arranged oppositely and an adsorbent filled between the two second air-permeable nets. The adsorbent can be activated carbon. The purification box 11 is provided with a discharge pipe 19, which is located at the downstream side of the purification layer 18. Therefore, after the gas is washed with water, it will first pass through the drying layer 17 for drying, and then pass through the purification layer 18 for adsorption and purification.

[0060] In summary, this device has the following characteristics:

[0061] 1. This device uses incineration to treat waste samples harmlessly. This treatment method is mature in technology and can disinfect and sterilize thoroughly;

[0062] 2. Before burning the waste samples, the device first uses a crushing mechanism to crush the waste samples uniformly and crush them into particles of similar size, so that the subsequent incineration will be more complete;

[0063] 3. The high-temperature exhaust gas generated by incineration will exchange heat with the waste sample being transported in the conveying box 4 through the spiral exhaust pipe 9 wound around the conveying box 4, thereby achieving drying and preheating of the waste sample, which helps to reduce the humidity of the waste sample and make the waste sample dry. In this way, the dry waste sample will be easier to be incinerated in the incinerator 7, reducing the energy consumption of the incinerator 7;

[0064] 4. After heat exchange and cooling, the exhaust gas will finally pass through the water washing component to remove the ash, and then pass through the purification component to dry and purify the odor before being discharged, which can reduce the pollution to the atmospheric environment;

[0065] 5. This device integrates the crushing, incineration, waste heat recovery and waste gas purification of waste samples. It can dispose of waste samples efficiently and harmlessly, with low energy consumption and low environmental pollution, and is easy to promote and use.
