The invention discloses an odor purification and feather collection recycling system and method. The invention discloses an odor purification and feather collection recycling method. The method comprises the following steps: step 1, a feather concentration and attachment step: blowing feathers of a pasture to a feather blocking net through a fan; and 2, feather positioning and preparation: selecting one of a centralized cleaning mode and a global cleaning mode, responding to the selected cleaning mode by a controller so as to plan a dynamic movement track of a sucking disc relative to a feather blocking net, and controlling a longitudinal guide rail and a transverse guide rail to cooperatively move by the controller. The odor purification and feather collection recycling system and method disclosed by the invention have the beneficial effects that two cleaning modes and two planning modes are provided, different feather distribution scenes of a pasture are flexibly adapted, accurate cleaning can be carried out on key areas, the efficiency can be improved, full-area coverage can be realized, dead angles can be avoided, and the requirements of automation and manual intervention are considered.

The invention relates to a sludge concentration tank, a sludge concentration system and an application method.The sludge concentration tank comprises a tank body (1), the interior of the tank body is composed of a gas collecting area (4), a settling area (5) and a sludge storage area (6) from top to bottom, the gas collecting area is provided with a gas outlet (7), the side wall of the settling area is provided with a sludge feeding pipe (8), and the upper portion of the settling area is provided with a liquid discharging pipe (12); a sludge discharge pipe (9) is arranged at the bottom of the sludge storage area; the rotational flow inner part (2) is arranged in the settling area, the rotational flow inner part is a cylinder with the pipe diameter reduced from top to bottom, an opening in the bottom of the rotational flow inner part is a mud outlet, the top of the rotational flow inner part is closed, a clear liquid outlet (16) is formed in the rotational flow inner part, and a feeding opening is formed in the side wall of the rotational flow inner part and communicated with the sludge feeding pipe. The sludge concentration tank and the sludge concentration system can realize efficient separation of sludge and water, and the subsequent sludge treatment energy consumption is reduced; meanwhile, gas is collected, and the deodorization effect is achieved. The working efficiency and the separation efficiency are relatively high.

The utility model relates to the technical field of closestool deodorization, and disclose a deodorization device for closestool, the back of closestool body is provided with filter assembly, exhaust component includes a plurality of support blocks and annular pipeline, a plurality of support blocks fixedly connected in the bottom of seat ring, the bottom of a plurality of support blocks is provided with the clamping groove, the annular pipeline is clamped in the inside of clamping groove, the inside of annular pipeline is provided with a plurality of air inlets, and the annular pipeline is connected with air inlet pipeline, the back of closestool body is provided with box, and the fan is installed on the box, and the top of box is provided with fixed component, when using the closestool body, the gas is introduced into the inside of box through air inlet pipeline, the activated carbon filter plate arranged in the inside of box can carry out deodorization to the gas that enters the inside of box, and the gas after deodorization is discharged through the fan, thereby reaching the effect of deodorization to the closestool body, and improving the comfort degree of closestool body use.

An odor-removing insole and its preparation method are disclosed. The odor-removing insole includes an upper and lower layer that can be interlocked, and odor-removing particles disposed between the upper and lower layers. The lower layer has an installation groove for installing the odor-removing particles, and the upper layer has ventilation holes opposite to the installation groove. The odor-removing particles are composed of the following raw materials: diatomaceous earth, zeolite powder, epoxy resin, lemon eucalyptus oil, zinc oxide, and magnesium stearate. By defining the specific structure of the insole, the invention provides ventilation holes in the upper layer opposite to the odor-removing particles. Volatile odorous gases generated inside the shoe enter the lower layer through the ventilation holes and are adsorbed by the odor-removing particles, thus keeping the air inside the shoe fresh.

The invention discloses a refrigerator and an odor removal control method. The method comprises the following steps: acquiring historical opening data of opening the refrigerator by a user; according to the historical opening data, refrigerator opening probabilities corresponding to the time intervals are predicted; determining a target time interval according to the refrigerator opening probability; determining a starting moment corresponding to the target time interval; based on the refrigerator opening probability corresponding to the adjacent time interval of the target time interval, the starting moment corresponding to the target time interval is corrected; and when the current moment reaches the corrected starting moment, starting the peculiar smell purification device. According to the method and the device, the starting time can adaptively follow the daily fluctuation of the door opening time when the user uses the refrigerator daily, so that the starting time of the peculiar smell purification device better fits the actual use habit of the user, and the peculiar smell purification device runs in the time interval when the user does not open the refrigerator as much as possible; and energy waste caused by invalid starting is avoided while the odor removal effect is guaranteed.

The utility model relates to the technical field of food additive waste gas treatment, and provides a food additive waste gas purification device which comprises a purification box and an air inlet pipe, a blow-off pipe is fixed on one side of the bottom of the purification box, a water storage tank is fixed on the other side of the bottom of the purification box, and a delivery pump is installed at the bottom of the water storage tank. An air inlet pipe is fixed on the outer wall of the purifying box above the blow-off pipe, and a door body is arranged on one side of the purifying box. The air suction structure is arranged, the air blower is started, purified air in the purification box enters the flow dividing air box through the air inlet pipe, then enters the air blower through the connecting air pipe and is exhausted from the output end of the air blower, and under the cooperation of the air blower and the air inlet pipe, the air flow speed in the purification box is increased; according to the food additive waste gas purification device, waste gas can be effectively collected and treated, the function of facilitating air suction of the device is achieved, and therefore the working efficiency of the food additive waste gas purification device in use is improved.
