Description

Technical Field

[0001] This application belongs to the technical field of dairy processing equipment, and specifically relates to a treatment box assembly for thermal processing waste gas in the production of processed cheese. Background Technology

[0002] The production of processed cheese requires thermal processing steps such as melting, mixing, and homogenization, which generates waste gas containing milk fat particles, protein aerosols, and volatile organic compounds.

[0003] In existing technologies, insufficient attention is paid to the treatment of exhaust gas after hot air drying. In a technical solution for a rapid slurry and powder dryer (publication number CN222231095U), the inventors suggest that some agglomerates are vibrated and turned into powder, flowing with the airflow from the powder conveying pipe into the settling cylinder. Some humid gas is heated by a hot air blower and turned into steam, which is then discharged through the hot air conveying pipe. This technical solution uses a single filtration or settling chamber, but it is difficult to efficiently separate micron-sized milk fat particles, and the equipment is prone to clogging, resulting in high maintenance costs. Furthermore, existing dryers offer low exhaust gas treatment, leading to milk fat particles easily adhering to the inner walls of the equipment, increasing the risk of microbial contamination. Direct emission of protein aerosols may also affect workshop air quality and the health of operators; and unrecovered milk fat and protein components in the exhaust gas cause raw material losses. Utility Model Content

[0004] The purpose of this invention is to address the problem that existing powder drying equipment cannot completely remove powder from the exhaust gas, and to provide a multi-stage separation and high-efficiency recovery exhaust gas treatment box assembly.

[0005] To achieve the above-mentioned technical objectives, the following technical solution is provided: a waste gas treatment box assembly for processed cheese production, comprising a conveying pipe for waste gas collection, a sedimentation tank assembly connected to the conveying pipe, and an exhaust pipe disposed above the sedimentation tank assembly.

[0006] The settling tank assembly includes an exhaust gas collection chamber assembly, which has at least two exhaust gas collection chambers. The first inlet of the exhaust gas collection chamber is located on the main body and is connected to the conveying pipe after being connected by a flange. It has an exhaust gas outlet at the upper end and a funnel-shaped first outlet at the lower end.

[0007] The dust collection chamber is located below the exhaust gas collection chamber group. The dust collection chamber is funnel-shaped, with the first outlet of all exhaust gas collection chambers connected to the upper plane, and the second outlet set at the center of the lower axis.

[0008] The exhaust gas transfer chamber is located above the exhaust gas collection chamber group and is connected to all exhaust gas outlets; the exhaust gas transfer chamber is also connected to the exhaust pipe.

[0009] In one feasible embodiment, a dust trap is installed inside the exhaust gas collection chamber. The dust trap is located inside the straight section of the exhaust gas collection chamber and includes at least three layers of interception plates, which are riveted to the side walls of the straight section.

[0010] In one feasible configuration, the interceptor plate extends downwards and towards the center of the exhaust gas collection chamber, forming an angle of 30°–45° with the cross-section of the exhaust gas collection chamber.

[0011] In one feasible embodiment, an inlet pipe is provided inside the first inlet, extending inward to contact the inner wall of the exhaust gas collection chamber.

[0012] In one feasible embodiment, the exhaust gas collection chamber has a top cover that is located above and connected to the first inlet;

[0013] The top cover is a spiral surface surrounding the exhaust outlet, and it gradually descends from the inner wall of the exhaust gas collection chamber that is in contact with the inlet pipe along the exhaust outlet.

[0014] In an feasible embodiment, the height ratio of the straight section to the funnel section of the exhaust gas collection chamber is 1:1.

[0015] Compared with the prior art, the present invention has the following advantages:

[0016] This application incorporates a settling tank assembly in the exhaust gas pipeline. The combination of multiple components increases the complexity of the flow within the settling tank, obstructing the movement path of dust and ensuring its complete settling within the dust collection chamber. Furthermore, the combination of a spiral guide and interceptor plates achieves staged interception of milk fat particles, with a separation efficiency exceeding 95%. The interceptor plates prevent dust from escaping within the exhaust gas collection chamber, and their angle facilitates dust settling. Moreover, the similar height of the straight section and the funnel section of the exhaust gas collection chamber prevents dust in the funnel section from easily returning to the straight section. The collected milk fat can be directly reused in production, reducing raw material costs. Attached Figure Description

[0020] Figure 2 This is a side view of Embodiment 1;

[0021] Figure 3 for Figure 2 Sectional view at point AA; Detailed Implementation

[0022] like Figure 1 , Figure 2 and Figure 3 The illustrated embodiment 1 describes a waste gas treatment enclosure assembly for processed cheese production, comprising a waste gas collection and delivery pipe 1, a sedimentation tank assembly 2 connected to the delivery pipe 1, and an exhaust pipe 3 disposed above the sedimentation tank assembly 2. In this embodiment, the sedimentation tank assembly 2 includes a waste gas collection chamber assembly 21, which has two waste gas collection chambers arranged side by side. The first inlet of each waste gas collection chamber is located on the main body and is connected to the delivery pipe 1 via a flange. The first inlet has a waste gas outlet at the upper end and a funnel-shaped first outlet at the lower end.

[0023] In addition, the exhaust gas collection chamber group 21 also includes a dust collection chamber 22, which is located below the exhaust gas collection chamber group 21. The dust collection chamber is funnel-shaped, with the first outlet of all the exhaust gas collection chambers connected to the upper plane, and the second outlet is set at the center of the lower axis.

[0024] In addition, the exhaust gas collection chamber group 21 also includes an exhaust gas transfer chamber 23, which is located above the exhaust gas collection chamber group 21. The exhaust gas transfer chamber 23 is connected to all exhaust gas outlets and is connected to the exhaust pipe 3.

[0025] Furthermore, in this embodiment, a dust trap is installed inside the exhaust gas collection chamber. The dust trap is located inside the straight section of the exhaust gas collection chamber and includes three layers of intercepting plates 4, which are riveted to the side wall of the straight section. The intercepting plates 4 extend downwards to the center of the exhaust gas collection chamber and form a 30° angle with the cross-section of the exhaust gas collection chamber, making it suitable for low-viscosity emulsions.

[0026] In this embodiment, an inlet pipe is provided inside the first inlet, extending inward to contact the inner wall of the exhaust gas collection chamber. The exhaust gas collection chamber has a top cover 5, which is located above the first inlet and connected to it. The top cover 5 is a spiral surface that wraps around the exhaust gas outlet, gradually descending from the inner wall of the exhaust gas collection chamber where it contacts the inlet pipe along the exhaust gas outlet.

[0027] In this embodiment, the height ratio of the straight section to the funnel section of the exhaust gas collection chamber is 1:1.

[0028] In Example 2, the interceptor plate 4 forms a 45° angle with the cross-section of the exhaust gas collection chamber, which is suitable for exhaust gases with high fat content and provides better anti-adhesion effect. The rest is the same as in Example 1.

[0029] The working principle of both Embodiment 1 and Embodiment 2 is the same: the conveying pipe 1 evenly delivers the exhaust gas into each exhaust gas collection chamber, and each exhaust gas collection chamber performs sedimentation treatment on the exhaust gas. The dust during processing enters the funnel section of the exhaust gas collection chamber and is collected in the dust collection chamber 22 through the first outlet. After the segmented processing of this application, the dust collection chamber 22 is basically in a windless state. Once the amount is sufficient, the operator can manually collect and remove it through the second outlet. Meanwhile, the hot air containing dust enters the exhaust gas collection chamber through the inlet pipe and is fixed in direction by the top cover 5 and the inner wall of the exhaust gas collection chamber, moving downwards in a spiral shape. This facilitates the dust entering the interceptor plate 4, resulting in zero dust content at the exhaust gas outlet.

[0030] Moreover, the above-mentioned technical solution can also be applied to the treatment of waste gas from the thermal processing of other dairy products (such as butter and whey powder), by adjusting the angle and flow rate of the interceptor plate to adapt to the characteristics of different materials.
